Abstract
BACKGROUND Although early-onset group B β-hemolytic streptococcus (GBS) infection is rare, it accounts for approximately 30% of neonatal infections, has a high mortality rate, and is acquired through vertical transmission from colonized mothers. Several trials have demonstrated the efficacy of intrapartum antibiotic prophylaxis (IAP) for preventing early-onset disease (EOD). Vaginal disinfection with chlorhexidine during labour has been proposed as another strategy for preventing GBS EOD in the preterm and term neonate. Chlorhexidine has been found to have no impact on antibiotic resistance, is inexpensive, and applicable to poorly equipped delivery sites. OBJECTIVES To determine the effectiveness of vaginal disinfection with chlorhexidine during labour in women who are colonized with GBS for preventing early-onset GBS infection in preterm and term neonates. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 October 2014) and reference lists of retrieved studies. SELECTION CRITERIA Randomized and quasi-randomized trials comparing vaginal disinfection with chlorhexidine (vaginal wash or gel/cream) versus placebo, or no treatment. DATA COLLECTION AND ANALYSIS Three review authors independently assessed the trials for inclusion and risk of bias, extracted the data and checked them for accuracy. MAIN RESULTS We identified no new trials eligible for inclusion in this update. One study was moved from included to excluded studies from the previous version of the review. Four studies, including 1125 preterm and term infants, met the inclusion criteria and reported on at least one of the outcomes of interest. For the comparison chlorhexidine (vaginal wash or gel) versus placebo or no treatment, two studies (n = 987) were pooled. There was no statistically significant difference in early-onset GBS disease (sepsis and/or meningitis) comparing chlorhexidine (vaginal wash or gel/cream) versus placebo or no treatment; risk ratio (RR), 2.32 (95% confidence interval (CI) 0.34 to 15.63); I-squared (I²) = 0% or in GBS pneumonia; RR 0.35 (95% CI 0.01 to 8.6); test for heterogeneity not applicable. The outcome of colonization of the neonate with GBS was reported in three studies (n = 328); RR 0.64 (95% CI 0.40 to 1.01; there was substantial between-study heterogeneity (Chi² = 3.19; P = 0.20; I² = 37%). Maternal mild side effects (stinging or local irritation) (three trials, 1066 women) were more commonly seen in women treated with chlorhexidine (RR 8.50 (95% CI 1.60 to 45.28); there was no heterogeneity (Chi² = 0.01, df = 1 (P = 0.91); I² = 0%). No side effects were reported among the neonates.For the comparison chlorhexidine vaginal wash verus mechanical washing with placebo or no treatment (one study, n = 79), there was a significant reduction in neonatal colonization with GBS; RR 0.32 (95% CI 0.12 to 0.90). Tests for heterogeneity not applicable. There were no other significant results for this comparison.For the comparison chlorhexidine gel or cream versus placebo or no treatment, there were no statistically significant results for the outcomes reported on.The quality of the trials varied and the overall risk of bias was rated as unclear or high. The quality of the evidence using GRADE was very low for the outcomes of the comparison chlorhexidine (vaginal wash or gel/cream) versus placebo or no treatment. These outcomes included: early-onset GBS disease (sepsis and/or meningitis), GBS pneumonia, neonatal colonization with GBS, neonatal mortality due to early-onset GBS infection and adverse (mild) effects in the mother and the neonate. AUTHORS' CONCLUSIONS The quality of the four included trials varied as did the risk of bias and the quality of the evidence using GRADE was very low. Vaginal chlorhexidine was not associated with reductions in any of the primary outcomes of early-onset GBS disease (sepsis and/or meningitis) or GBS pneumonia. Vaginal chlorhexidine may reduce GBS colonization of neonates. The intervention was associated with an increased risk of maternal mild adverse effects. The review currently does not support the use of vaginal disinfection with chlorhexidine in labour for preventing early-onset disease. Results should be interpreted with caution as the methodological quality of the studies was poor. As early-onset GBS disease is a rare condition trials with very large sample sizes are needed to assess the effectiveness of vaginal chlorhexidine to reduce its occurrence. In the era of intrapartum antibiotic prophylaxis, such trials may be difficult to justify especially in developed countries.

Abstract
BACKGROUND Surfactant replacement therapy has been proven beneficial in the prevention and treatment of neonatal respiratory distress syndrome (RDS). The deficiency of surfactant or surfactant dysfunction may contribute to respiratory failure in a broader group of disorders, including meconium aspiration syndrome (MAS). OBJECTIVES To evaluate the effect of surfactant administration in the treatment of late preterm and term infants with meconium aspiration syndrome. SEARCH METHODS We searched The Cochrane Library (Issue 4, 2006), MEDLINE and EMBASE (1985 to December 2006), previous reviews including cross-references, abstracts, conference and symposia proceedings, expert informants, and journal handsearching, without language restrictions. We contacted study authors for additional data.We ran an updated search in November 2014 and searched the following sites for ongoing or recently completed trials: www.clinicaltrials.gov; www.controlled-trials.com; and www.who.int/ictrp. SELECTION CRITERIA Randomised controlled trials which evaluated the effect of surfactant administration in late preterm and term infants with meconium aspiration syndrome are included in the analyses. DATA COLLECTION AND ANALYSIS We extracted data on clinical outcomes including mortality, treatment with extracorporeal membrane oxygenation (ECMO), pneumothorax, duration of assisted ventilation, duration of supplemental oxygen, intraventricular haemorrhage (any grade and severe IVH), and chronic lung disease. We conducted data analyses in accordance with the standards of the Cochrane Neonatal Review Group. MAIN RESULTS Four randomised controlled trials met our inclusion criteria. The meta-analysis of four trials (326 infants) showed no statistically significant effect on mortality [typical risk ratio (RR) 0.98, 95% confidence interval (CI) 0.41 to 2.39; typical risk difference (RD) -0.00, 95% CI -0.05 to 0.05]. There was no heterogeneity for this outcome (I² = 0% for both RR and RD). The risk of requiring extracorporeal membrane oxygenation was significantly reduced in a meta-analysis of two trials (n = 208); [typical RR 0.64, 95% CI 0.46 to 0.91; typical RD -0.17, 95% CI -0.30 to -0.04; number needed to treat for an additional beneficial outcome (NNTB) 6, 95% CI 3 to 25]. There was no heterogeneity for RR (1² = 0%) but moderate heterogeneity for RD (I² = 50%). One trial (n = 40) reported a statistically significant reduction in the length of hospital stay (mean difference -8 days, 95% CI -14 to -3 days; test for heterogeneity not applicable). There were no statistically significant reductions in any other outcomes studied (duration of assisted ventilation, duration of supplemental oxygen, pneumothorax, pulmonary interstitial emphysema, air leaks, chronic lung disease, need for oxygen at discharge or intraventricular haemorrhage). AUTHORS' CONCLUSIONS In infants with MAS, surfactant administration may reduce the severity of respiratory illness and decrease the number of infants with progressive respiratory failure requiring support with ECMO. The relative efficacy of surfactant therapy compared to, or in conjunction with, other approaches to treatment including inhaled nitric oxide, liquid ventilation, surfactant lavage and high frequency ventilation remains to be tested.

Abstract
BACKGROUND Maternal colonization with group B streptococcus (GBS) during pregnancy increases the risk of neonatal infection by vertical transmission. Administration of intrapartum antibiotic prophylaxis (IAP) during labor has been associated with a reduction in early onset GBS disease (EOGBSD). However, treating all colonized women during labor exposes a large number of women and infants to possible adverse effects without benefit. OBJECTIVES To assess the effect of intrapartum antibiotics for maternal Group B haemolytic streptococci (GBS) colonization on mortality from any cause, from GBS infection and from organisms other than GBS. SEARCH METHODS We updated the search of the Cochrane Pregnancy and Childbirth Group's Trials Register on 11 March 2014. SELECTION CRITERIA Randomized trials assessing the impact of maternal IAP on neonatal GBS infections were included. DATA COLLECTION AND ANALYSIS We independently assessed eligibility and quality of the studies. MAIN RESULTS We did not identify any new trials from the updated search so the results remain unchanged as follows.We included four trials involving 852 women.Three trials (involving 500 women) evaluating the effects of IAP versus no treatment were included. The use of IAP did not significantly reduce the incidence of all cause mortality, mortality from GBS infection or from infections caused by bacteria other than GBS. The incidence of early GBS infection was reduced with IAP compared to no treatment (risk ratio (RR) 0.17, 95% confidence interval (CI) 0.04 to 0.74, three trials, 488 infants; risk difference -0.04, 95% CI -0.07 to -0.01; number needed to treat to benefit 25, 95% CI 14 to 100, I² 0%). The incidence of LOD or sepsis from organisms other than GBS and puerperal infection was not significantly different between groups.One trial (involving 352 women) compared intrapartum ampicillin versus penicillin and reported no significant difference in neonatal or maternal outcomes.We found a high risk of bias for one or more key domains in the study methodology and execution. AUTHORS' CONCLUSIONS Intrapartum antibiotic prophylaxis appeared to reduce EOGBSD, but this result may well be due to bias as we found a high risk of bias for one or more key domains in the study methodology and execution. There is lack of evidence from well designed and conducted trials to recommend IAP to reduce neonatal EOGBSD.Ideally the effectiveness of IAP to reduce neonatal GBS infections should be studied in adequately sized double-blind controlled trials. The opportunity to conduct such trials has likely been lost, as practice guidelines (albeit without good evidence) have been introduced in many jurisdictions.

Abstract
BACKGROUND Low plasma levels of erythropoietin (EPO) in preterm infants provide a rationale for the use of EPO to prevent or treat anaemia. OBJECTIVES To assess the effectiveness and safety of early initiation of EPO or darepoetin (initiated before eight days after birth) in reducing red blood cell (RBC) transfusions in preterm and/orlow birth weight infants. SEARCH METHODS The Cochrane Library, MEDLINE, EMBASE, CINAHL, reference lists of identified trials and reviews, Pediatric Academic Societies Annual meetings 2000 to 2013 (Abstracts2View(TM)) and clinical trials registries (clinicaltrials.gov; controlled-trials.com; and who.int/ictrp) were searched in July 2013. SELECTION CRITERIA Randomised or quasi-randomised controlled trials of early (< eight days of age) initiation of EPO treatment versus placebo or no intervention in preterm and/or low birth weightinfants. DATA COLLECTION AND ANALYSIS The methods of the Neonatal Cochrane Review Group were used. MAIN RESULTS The updated review includes 27 studies enrolling 2209 infants. One study enrolling infants at a mean age of > eight days and one duplicate publication were excluded. One new study using darepoetin was identified.Early EPO reduced the risk of the 'use of one or more RBC transfusions' (typical risk ratio (RR) 0.79, 95% confidence interval (CI) 0.73 to 0.85; typical risk difference (RD) -0.14, 95% CI -0.18 to -0.10; I(2) = 54% for both; number needed to treat to benefit (NNTB) 7, 95% CI 6 to 10; 16 studies, 1661 infants).The total volume of RBCs transfused per infant was reduced (typical mean difference (MD) 7 mL/kg, 95% CI -12 to - 2; I(2) = 63%; 7 studies, 581 infants). The number of RBC transfusions per infant was minimally reduced (typical MD -0.27, 95% CI -0.42 to -0.12; I(2) = 64%; 13 studies, 951 infants). The number of donors to whom the infants were exposed was significantly reduced (MD-0.54, 95% CI -0.89 to -0.20; I(2) = 0%; 3 studies, 254 infants).There was a non-significant increase in the risk of stage ≥ 3 retinopathy of prematurity (ROP) with early EPO (typical RR 1.37, 95% CI 0.87 to 2.17; I(2) = 0%; typical RD 0.03, 95% CI -0.01 to 0.06; I(2) = 29%; 7 studies, 801 infants). A post hoc analysis including all studies that reported on ROP stage ≥ 3, regardless of the age of the infant when EPO treatment was started, showed a significantly increased typical RR of 1.48 (95% CI 1.02 to 2.13; P = 0.04; I(2) = 0%) and typical RD of 0.03 (95% CI 0.00 to 0.06; P = 0.03; I(2) = 50%; 10 studies, 1303 infants) with a number needed to treat to harm (NNTH) of 33 (95% CI 17 to infinity). In an Italian study in which the authors compared the use of early intravenous EPO with subcutaneous EPO the overall incidence of stage ≥ 3 was 15%, similar to the incidence of 17% in the study by Romagnoli and co-workers.The rates for mortality and morbidities including intraventricular haemorrhage and necrotizing enterocolitis were not significantly changed by early EPO treatment. Neurodevelopmental outcomes at 18 to 22 months varied. AUTHORS' CONCLUSIONS Early administration of EPO reduces the use of RBC transfusions, the volume of RBCs transfused, and donor exposure after study entry. The small reductions are likely to be of limited clinical importance. Donor exposure is probably not avoided since all but one study included infants who had received RBC transfusions prior to trial entry. In this update there was no significant increase in the rate of ROP (stage ≥ 3) for studies that initiated EPO treatment at less than eight days of age. In a post hoc analysis including all studies that reported on ROP stage ≥ 3 regardless of age at initiation of treatment there was an increased risk of ROP. The rates for mortality and morbidities including intraventricular haemorrhage and necrotizing enterocolitis were not significantly changed by early EPO treatment. Neurodevelopmental outcomes at 18 to 22 months vary in the studies published to date. Ongoing research should deal with the issue of ROP and evaluate current clinical practice that will limit donor exposure. Due to the limited benefits and the possibly increased risk of ROP, administration of EPO is not recommended. Darbepoetin requires further study. The possible neuroprotective role of EPO in neonates will be reviewed in separate Cochrane reviews.

Abstract
BACKGROUND Low plasma levels of erythropoietin (EPO) in preterm infants provide a rationale for the use of EPO to prevent or treat anaemia. OBJECTIVES To assess the effectiveness and safety of late initiation of erythropoietin (EPO) between eight and 28 days after birth, in reducing the use of red blood cell (RBC) transfusions in preterm and/or low birth weight infants. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and CINAHL in July 2013. Additional searches included the Pediatric Academic Societies Annual Meetings from 2000 to 2013 (Abstracts2View™) and clinical trials registries (www.clinicaltrials.gov; www.controlled-trials.com; and who.int/ictrp/en). For this update we moved one study from the early EPO review to this late EPO review. SELECTION CRITERIA Randomised or quasi-randomised controlled trials of late initiation of EPO treatment (started at ≥ eight days of age) versus placebo or no intervention in preterm (< 37 weeks) and/or low birth weight (< 2500 g) neonates. DATA COLLECTION AND ANALYSIS We performed data collection and analyses in accordance with the methods of the Cochrane Neonatal Review Group. MAIN RESULTS We include 30 studies (31 comparisons) randomising 1591 preterm infants. Literature searches in 2013 did not identify any new study for inclusion. For this update we moved one study enrolling 230 infants from the early EPO review to this late EPO review.Most included trials were of small sample size. The meta-analysis showed a significant effect of the use of one or more RBC transfusions (20 studies (n = 1142); typical risk ratio (RR) 0.71, 95% confidence interval (CI) 0.64 to 0.79; typical risk difference (RD) -0.17, 95% CI -0.22 to -0.12; typical number needed to treat for an additional beneficial outcome (NNTB) 6, 95% CI 5 to 8). There was moderate heterogeneity for this outcome (RR I² = 68%; RD I² = 60%). We obtained similar results in secondary analyses based on different combinations of high/low doses of EPO and iron supplementation. There was no significant reduction in the total volume (mL/kg) of blood transfused per infant [typical mean difference (MD) -1.6 mL/kg, 95% CI -5.8 to 2.6); 5 studies, 197 infants]. There was high heterogeneity for this outcome (I² = 92%). There was a significant reduction in the number of transfusions per infant (11 studies enrolling 817 infants; typical MD -0.22, 95% CI -0.38 to -0.06). There was high heterogeneity for this outcome (I² = 94%).Three studies including 404 infants reported on retinopathy of prematurity (ROP) (all stages or stage not reported), with a typical RR 1.27 (95% CI 0.99 to 1.64) and a typical RD of 0.09 (95% CI -0.00 to 0.18). There was high heterogeneity for this outcome for both RR (I² = 83%) and RD (I² = 82%). Three trials enrolling 442 infants reported on ROP (stage ≥ 3). The typical RR was 1.73 (95% CI 0.92 to 3.24) and the typical RD was 0.05 (95% CI -0.01 to 0.10). There was minimal heterogeneity for this outcome for RR (I² = 18%) but high heterogeneity for RD (I² = 79%). There were no significant differences in other clinical outcomes. There was no reduction in necrotizing enterocolitis in spite of a reduction in the use of RBC transfusions. Long-term neurodevelopmental outcomes were not reported. AUTHORS' CONCLUSIONS Late administration of EPO reduces the use of one or more RBC transfusions, the number of RBC transfusions per infant (< 1 transfusion per infant) but not the total volume (ml/kg) of RBCs transfused per infant. Any donor exposure is likely not avoided as most studies included infants who had received RBC transfusions prior to trial entry. Late EPO does not significantly reduce or increase any clinically important adverse outcomes except for a trend in increased risk for ROP. Further research of the use of late EPO treatment to prevent donor exposure is not indicated. Research efforts should focus on limiting donor exposure during the first few days of life in sick neonates, when RBC requirements are most likely to be required and cannot be prevented by late EPO treatment. The use of satellite packs (dividing one unit of donor blood into many smaller aliquots) may reduce donor exposure.

Abstract
IMPORTANCE A single course of antenatal corticosteroid therapy is recommended for pregnant women at risk of preterm birth between 24 and 33 weeks' gestational age. However, 50% of women remain pregnant 7 to 14 days later, leading to the question of whether additional courses should be given to women remaining at risk for preterm birth. The Multiple Courses of Antenatal Corticosteroids for Preterm Birth Study (MACS) was an international randomized clinical trial that compared multiple courses of antenatal corticosteroids with a single course in women at risk of preterm birth. OBJECTIVE To determine the effects of single vs multiple courses of antenatal corticosteroid therapy on death or neurodevelopmental disability (neuromotor, neurosensory, or neurocognitive/neurobehavioral function) at 5 years of age in children whose mothers participated in MACS. Our secondary aims were to determine the effect on height, weight, head circumference, blood pressure, intelligence, and specific cognitive (visual, spatial, and language) skills. DESIGN, SETTING, AND PARTICIPANTS Cohort follow-up study of children seen between June 2006 and May 2012 at 55 centers. In total, 1724 women (2141 children) were eligible for the study, of whom 1728 children (80.7% of the 2141 eligible children) participated and 1719 children contributed to the primary outcome. INTERVENTION Single and multiple courses of antenatal corticosteroid therapy. MAIN OUTCOMES AND MEASURES The primary outcome was death or survival with a neurodevelopmental disability in 1 of the following domains: neuromotor (nonambulatory cerebral palsy), neurosensory (blindness, deafness, or need for visual/hearing aids), or neurocognitive/neurobehavioral function (abnormal attention, memory, or behavior). RESULTS There was no significant difference between the groups in the risk of death or neurodevelopmental disability: 217 of 871 children (24.9%) in the multiple-courses group vs 210 of 848 children (24.8%) in the single-course group (odds ratio, 1.02 [95% CI, 0.81 to 1.29]; P = .84). CONCLUSIONS AND RELEVANCE Multiple courses, compared with a single course, of antenatal corticosteroid therapy did not increase or decrease the risk of death or disability at 5 years of age. Because of a lack of strong conclusive evidence of short-term or long-term benefits, it remains our opinion that multiple courses not be recommended in women with ongoing risk of preterm birth.

Abstract
BACKGROUND Acute hypoxaemic respiratory failure (AHRF) is an important cause of mortality and morbidity in children. Positive pressure ventilation is currently the standard care, however, it does have complications. Continuous negative extrathoracic pressure (CNEP) ventilation or continuous positive airway pressure (CPAP) ventilation delivered via non-invasive approaches (Ni-CPAP) have shown certain beneficial effects in animal and uncontrolled human studies. OBJECTIVES To assess the effectiveness of CNEP or Ni-CPAP compared to conventional ventilation in children (at least one month old and less than 18 years of age) with AHRF due to non-cardiogenic causes for improving the mortality or morbidity associated with AHRF. SEARCH METHODS We searched CENTRAL 2013, Issue 6, MEDLINE (January 1966 to June week 3, 2013), EMBASE (1980 to July 2013) and CINAHL (1982 to July 2013). SELECTION CRITERIA Randomised or quasi-randomised clinical trials of CNEP or Ni-CPAP versus standard therapy (including positive pressure ventilation) involving children (from one month old to less than 18 years at time of randomisation) who met the criteria for diagnosis of AHRF with at least one of the outcomes reported. DATA COLLECTION AND ANALYSIS We assessed risk of bias of the included studies using allocation concealment, blinding of intervention, completeness of follow-up and blinding of outcome measurements. We abstracted data on relevant outcomes and estimated the effect size by calculating risk ratio (RR) and risk difference (RD) with 95% confidence intervals (CI). MAIN RESULTS We identified two eligible studies: one of CPAP and one of CNEP (published as an abstract). Both were unblinded studies with mainly unclear risk of bias due to lack of adequate information to assess this. The CPAP study enrolled 37 children to oxygen mask and CPAP and reported improvement in respiratory rate and oxygen saturation in both arms after 30 minutes of application. The CNEP study was published as an abstract and included 33 infants with bronchiolitis. In the CNEP study there was a reduction in the fraction of inspired oxygen (FiO2) (less than 30% within one hour of initiation of therapy) in four participants in the CNEP group compared to none in the control group (RR 10.7, 95% CI 0.6 to 183.9). One infant required CPAP and mechanical ventilation in the control group while all infants in the CNEP group were managed without intubation (RR for both outcomes 0.40, 95% CI 0.02 to 9.06). None of the trials reported on mortality. No adverse events were reported in ether of the included trials. AUTHORS' CONCLUSIONS There is a lack of well-designed, controlled trials of non-invasive modes of respiratory support in children with AHRF. Studies assessing the outcomes mortality, avoidance of intubation and its associated complications, hospital stay and patient comfort are needed.

Abstract
BACKGROUND Twin birth is associated with a higher risk of adverse perinatal outcomes than singleton birth. It is unclear whether planned cesarean section results in a lower risk of adverse outcomes than planned vaginal delivery in twin pregnancy. METHODS We randomly assigned women between 32 weeks 0 days and 38 weeks 6 days of gestation with twin pregnancy and with the first twin in the cephalic presentation to planned cesarean section or planned vaginal delivery with cesarean only if indicated. Elective delivery was planned between 37 weeks 5 days and 38 weeks 6 days of gestation. The primary outcome was a composite of fetal or neonatal death or serious neonatal morbidity, with the fetus or infant as the unit of analysis for the statistical comparison. RESULTS A total of 1398 women (2795 fetuses) were randomly assigned to planned cesarean delivery and 1406 women (2812 fetuses) to planned vaginal delivery. The rate of cesarean delivery was 90.7% in the planned-cesarean-delivery group and 43.8% in the planned-vaginal-delivery group. Women in the planned-cesarean-delivery group delivered earlier than did those in the planned-vaginal-delivery group (mean number of days from randomization to delivery, 12.4 vs. 13.3; P=0.04). There was no significant difference in the composite primary outcome between the planned-cesarean-delivery group and the planned-vaginal-delivery group (2.2% and 1.9%, respectively; odds ratio with planned cesarean delivery, 1.16; 95% confidence interval, 0.77 to 1.74; P=0.49). CONCLUSIONS In twin pregnancy between 32 weeks 0 days and 38 weeks 6 days of gestation, with the first twin in the cephalic presentation, planned cesarean delivery did not significantly decrease or increase the risk of fetal or neonatal death or serious neonatal morbidity, as compared with planned vaginal delivery.

Abstract
BACKGROUND The potential benefits and harms of different lighting in neonatal units have not been quantified. OBJECTIVES To compare the effectiveness of cycled lighting (CL) (approximately 12 hours of light on and 12 hours of light off) with irregularly dimmed light (DL) or near darkness (ND) and with continuous bright light (CBL) on growth in preterm infants at three and six months of age. SEARCH METHODS We conducted electronic searches of the literature (in January 2013) of the Cochrane Central Register of Controlled Trials, Issue 12, 2012 (CENTRAL), MEDLINE, EMBASE, CINAHL and abstracts from Pediatric Academic Societies' annual meetings. We searched Controlled-trials.com and Clinicaltrials.gov for ongoing trials and abstracts from the Pediatric Academic Societies (PAS) Annual Meetings (2000 to 2013) using the Abstracts2view website on 10 May 2013. SELECTION CRITERIA Randomized or quasi-randomised trials of CL versus ND or CBL in preterm and low birth weight infants. DATA COLLECTION AND ANALYSIS We performed data collection and analyses according to the methods of the Cochrane Neonatal Review Group. MAIN RESULTS Six studies enrolling 424 infants compared CL versus ND (including one additional trial identified in this update that enrolled 37 infants). No study reported on weight at three or six months. In one study (n = 40), there was no statistically significant difference in weight at four months between the CL and ND groups. In another study (n = 62), the ratio of day-night activity prior to discharge favoured the CL group (mean difference (MD) 0.18, 95% confidence interval (CI) 0.17 to 0.19) indicating 18% more activity during the day than during the night in the CL group compared with the ND group. Two studies (n = 189) reported on retinopathy of prematurity (stage ≥ 3). There was no statistically significant difference between the CL and ND groups (typical risk ratio (RR) 0.53, 95% CI 0.25 to 1.11, I(2) = 0%; typical risk difference (RD) -0.09, 95% CI -0.19 to 0.01, I(2) = 0%). Two studies (n = 77) reported on length of hospital stay (days). There was a significant reduction in the length of stay between the CL and the ND groups favouring the CL group (MD -13 days, 95% CI -2 to -23). One study (n = 37) reported on less crying at 11 weeks' corrected age (CA) in the CL group compared with the ND group (MD -0.57 hours/24 hours, 95% CI -1.09 to -0.05).There was no heterogeneity for this outcome (I(2) = 0%).Two studies enrolling 82 infants compared CL versus CBL. One study (n = 41) reported higher mean weight at three months' CA in infants cared for in the CL nursery (P value < 0.02) and lower mean number of hours spent awake in 24 hours at three months of age (P value < 0.005). One study (n = 41) reported shorter time on ventilator in the CL compared with the CBL group (MD -18.2 days, 95% CI -31.40 to -5.0). One study (n = 41) reported a shorter time to first oral feeding in the CL group (MD -6.8 days, 95% CI -13.29 to -0.31).For many outcomes, the trends favoured CL versus ND as well as CL versus CBL.We identified no safety issues. AUTHORS' CONCLUSIONS Trials assessing the effect of CL have enrolled 506 infants. Trends for many outcomes favoured CL compared with ND and CL compared with CBL. The studies may have lacked significance due to a lack of statistical power. Future research should focus on comparing CL to ND.

Abstract
BACKGROUND Neonates are at higher risk of infection due to immuno-incompetence. Maternal transport of immunoglobulins to the fetus mainly occurs after 32 weeks' gestation, and endogenous synthesis begins several months after birth. Administration of intravenous immunoglobulin (IVIG) provides immunoglobulin G (IgG) that can bind to cell surface receptors, provide opsonic activity, activate complement, promote antibody-dependent cytotoxicity and improve neutrophilic chemo-luminescence. Theoretically, infectious morbidity and mortality could be reduced by the administration of IVIG. OBJECTIVES To assess the effects of IVIG on mortality/morbidity caused by suspected or proven infection at study entry in neonates. To assess in a subgroup analysis the effects of IgM-enriched IVIG on mortality from suspected infection. SEARCH METHODS For this update, MEDLINE, EMBASE, The Cochrane Library, CINAHL, trial registries, Web of Science, reference lists of identified studies, meta-analyses and personal files were searched in 2013. No language restrictions were applied. SELECTION CRITERIA Randomised or quasi-randomised controlled trials; newborn infants (< 28 days old); IVIG for treatment of suspected or proven bacterial/fungal infection compared with placebo or no intervention; one of the following outcomes was reported: mortality, length of hospital stay or psychomotor development at follow-up. DATA COLLECTION AND ANALYSIS Statistical analyses included typical risk ratio (RR), risk difference (RD), weighted mean difference (WMD), number needed to treat for an additional beneficial outcome (NNTB) or an additional harmful outcome (NNTH) (all with 95% confidence intervals (CIs) and the I-squared (I(2)) statistic to examine for statistical heterogeneity). MAIN RESULTS The updated search identified one published study and one ongoing study. A total of eight studies evaluating 3871 infants are included in this review.Mortality during hospital stay in infants with clinically suspected infection at trial entry was not significantly different after IVIG treatment (8 studies (n = 2425); typical RR 0.94, 95% CI 0.80 to 1.12; typical RD -0.01, 95% CI - 0.04 to 0.02 I(2) = 28% for RR and 32% for RD). Death or major disability at 2 years corrected age was not significantly different in infants with suspected infection after IVIG treatment (one study (n = 1985); RR 0.98, 95% CI 0.88 to 1.09 RD -0.01, 95% CI -0.05 to 0.03). Mortality during hospital stay was not significantly different after IVIG treatment in infants with proven infection at trial entry (RR 0.95, 95% CI 0.74 to 1.21 RD -0.01, 95% CI -0.04 to 0.03). Death or major disability at 2 years corrected age was not significantly different after IVIG treatment in infants with proven infection at trial entry (RR 1.03, 95% CI 0.91 to 1.18; RD 0.01, 95% CI -0.04 to 0.06). Mortality during hospital stay in infants with clinically suspected or proven infection at trial entry was not significantly different after IVIG treatment (1 study (n = 3493); RR 1.00, 95% CI 0.86 to 1.16; RD 0.00, 95% CI - 0.02 to 0.03). Death or major disability at 2 years corrected age was not significantly different after IVIG treatment in infants with suspected or proven infection at trial entry (1 study (n = 3493); RR 1.00, 95% CI 0.92 to 1.09; RD -0.00, 95% CI -0.03 to 0.03). Length of hospital stay was not reduced for infants with suspected/proven infection at trial entry (1 study (n = 3493); mean difference (MD) 0.00 days, 95% CI -0.61 to 0.61). No significant difference in mortality during hospital stay after IgM-enriched IVIG treatment for suspected infection was reported at trial entry (3 studies (n = 164); typical RR 0.57, 95% CI 0.31 to 1.04; RD -0.12, 95% CI -0.24 to 0.00 ; P = 0.06); I(2) = 2% for RR and 0% for RD). AUTHORS' CONCLUSIONS In previous reviews, we encouraged researchers to undertake well-designed trials to confirm or refute the effectiveness of IVIG in reducing adverse outcomes in neonates with suspected infection. Such a trial has been undertaken. Results of the INIS trial, which enrolled 3493 infants, carry a heavy weight in the current update of this review, and the undisputed results show no reduction in death or major disability at 2 years of age. Routine administration of IVIG to prevent mortality in infants with suspected or proven neonatal infection is not recommended.

Abstract
BACKGROUND Nosocomial infections continue to be a significant cause of morbidity and mortality among preterm and/or low birth weight (LBW) infants. Preterm infants are deficient in immunoglobulin G (IgG); therefore, administration of intravenous immunoglobulin (IVIG) may have the potential of preventing or altering the course of nosocomial infections. OBJECTIVES To use systematic review/meta-analytical techniques to determine whether IVIG administration (compared with placebo or no intervention) to preterm (< 37 weeks' postmenstrual age (PMA) at birth) or LBW (< 2500 g birth weight) infants or both is effective/safe in preventing nosocomial infection. SEARCH METHODS For this update, MEDLINE, EMBASE, CINAHL, The Cochrane Library, Controlled Trials, ClinicalTrials.gov and PAS Abstracts2view were searched in May 2013. SELECTION CRITERIA We selected randomised controlled trials (RCTs) in which a group of participants to whom IVIG was given was compared with a control group that received a placebo or no intervention for preterm (< 37 weeks' gestational age) and/or LBW (< 2500 g) infants. Studies that were primarily designed to assess the effect of IVIG on humoral immune markers were excluded, as were studies in which the follow-up period was one week or less. DATA COLLECTION AND ANALYSIS Data collection and analysis was performed in accordance with the methods of the Cochrane Neonatal Review Group. MAIN RESULTS Nineteen studies enrolling approximately 5000 preterm and/or LBW infants met inclusion criteria. No new trials were identified in May 2013.When all studies were combined, a significant reduction in sepsis was noted (typical risk ratio (RR) 0.85, 95% confidence interval (CI) 0.74 to 0.98; typical risk difference (RD) -0.03, 95% CI 0.00 to -0.05; number needed to treat for an additional beneficial outcome (NNTB) 33, 95% CI 20 to infinity), and moderate between-study heterogeneity was reported (I(2) 54% for RR, 55% for RD). A significant reduction of one or more episodes was found for any serious infection when all studies were combined (typical RR 0.82, 95% CI 0.74 to 0.92; typical RD -0.04, 95% CI -0.02 to -0.06; NNTB 25, 95% CI 17 to 50), and moderate between-study heterogeneity was observed (I(2) 50% for RR, 62% for RD). No statistically significant differences in mortality from all causes were noted (typical RR 0.89, 95% CI 0.75 to 1.05; typical RD -0.01, 95% CI -0.03 to 0.01), and no heterogeneity for RR (I(2) = 21%) or low heterogeneity for RD was documented (I(2) = 28%). No statistically significant difference was seen in mortality from infection; in incidence of necrotizing enterocolitis (NEC), bronchopulmonary dysplasia (BPD) or intraventricular haemorrhage (IVH) or in length of hospital stay. No major adverse effects of IVIG were reported in any of these studies. AUTHORS' CONCLUSIONS IVIG administration results in a 3% reduction in sepsis and a 4% reduction in one or more episodes of any serious infection but is not associated with reductions in other clinically important outcomes, including mortality. Prophylactic use of IVIG is not associated with any short-term serious side effects.The decision to use prophylactic IVIG will depend on the costs and the values assigned to the clinical outcomes. There is no justification for conducting additional RCTs to test the efficacy of previously studied IVIG preparations in reducing nosocomial infections in preterm and/or LBW infants.

Abstract
BACKGROUND Indomethacin is used as standard therapy to close a patent ductus arteriosus (PDA) but is associated with reduced blood flow to several organs. Ibuprofen, another cyclo-oxygenase inhibitor, may be as effective as indomethacin with fewer side effects. OBJECTIVES To determine the efficacy and safety of ibuprofen for closing a PDA in preterm and/or low birth weight infants. Seperate comparisons are presented for 1. ibuprofen (iv) compared with placebo; 2. ibuprofen (oral) compared with placebo; 3. ibuprofen (oral or iv) compared with other cyclo-oxygenase inhibitors (given iv or orally); 4. ibuprofen (oral) versus indomethacin (given iv or orally); 5. ibuprofen (oral) versus iv ibuprofen; 6. high dose versus standard dose of iv ibuprofen; 7. early versus expectant administration of iv ibuprofen. SEARCH METHODS We searched The Cochrane Library, MEDLINE, EMBASE, Clincialtrials.gov, Controlled-trials.com, www.abstracts2view.com/pas, and personal files in July 2012. SELECTION CRITERIA Randomised or quasi-randomised controlled trials of ibuprofen for the treatment of a PDA in newborn infants. DATA COLLECTION AND ANALYSIS Data collection and analysis conformed to the methods of the Cochrane Neonatal Review Group. MAIN RESULTS Twenty-seven studies are included in this review. One study (n = 136) compared iv ibuprofen versus placebo. Ibuprofen reduced the composite outcome of infant deaths, infants who dropped out or required rescue treatment; risk ratio (RR) 0.58 (95% confidence interval (CI) 0.38 to 0.89); risk difference (RD) -0.22 (95% CI -0.38 to -06); number needed to benefit (NNTB) 5 (95% CI 3 to 17). One study (n = 64) compared oral ibuprofen with placebo. There was a significant reduction in the failure rate to close a PDA; RR 0.26 (95% CI 0.11 to 0.62); RD -0.44 (95% CI -0.65 to -0.23); NNTB 2 (95% CI 2 to 4). Failure rates for PDA closure with ibuprofen (oral or iv) compared with indomethacin (oral or iv) was reported in 20 studies (n = 1019 infants). There was no significant difference between the groups; typical RR 0.98 (95% CI 0.80 to 1.20) I(2) = 0%; typical RD -0.01 (95% CI -0.06 to 0.05); I(2) = 0%. The risk of developing necrotising enterocolitis (NEC) was reduced for ibuprofen (15 studies (n = 865); typical RR 0.68 (95% CI 0.47 to 0.99); typical RD -0.04 (95% CI -0.08 to -0.00; (P = 0.04); NNTB 25 (95% CI 13, infinity); I(2) = 0%). The duration of ventilatory support was reduced with ibuprofen (oral or iv) compared with iv or oral indomethacin (six studies, n = 471) mean difference (MD) -2.35 days (95% CI -3.71 to -0.99); I(2) = 19%. Failure rates for PDA closure with oral ibuprofen compared with indomethacin (oral or iv) were reported in seven studies (n = 189 infants). There was no significant difference between the groups; typical RR 0.82 (95% CI 0.52 to 1.29); typical RD -0.06 (95% CI -0.18 to 0.06). The risk of NEC was reduced with oral ibuprofen compared with indomethacin (oral or iv) six studies (n = 166); typical RR 0.44 (95% CI 0.23 to 0.82); RD -0.15 (95% CI -0.25 to -0.04); NNTB 7 (95% CI 4 to 25). There was no heterogeneity for this outcome. There was a decreased risk of failure to close a PDA with oral ibuprofen compared with iv ibuprofen, three studies (n = 236) typical RR 0.37 (95% CI 0.23 to 0.61); typical RD -0.24 (95% CI -0.35 to -0.13); NNTB 4 (95% CI 3 to 8). There was less evidence of transient renal insufficiency in infants who received ibuprofen compared with indomethacin. High dose versus standard dose of iv ibuprofen and early versus expectant administration of iv ibuprofen have only been studied in two trials. AUTHORS' CONCLUSIONS Ibuprofen is as effective as indomethacin in closing a PDA and reduces the risk of NEC and transient renal insufficiency. Given the reduction in NEC ibuprofen currently appears to be the drug of choice. Oro-gastric administration of ibuprofen appears at least as effective as iv administration. Too few patients have been enrolled in studies assessing the effectiveness of a high dose of ibuprofen versus the standard dose and early versus expectant administration of ibuprofen to make recommendations. Studies are needed to evaluate the effect of ibuprofen compared with indomethacin treatment on longer-term outcomes in infants with PDA.

Abstract
BACKGROUND A patent ductus arteriosus (PDA) with significant left to right shunt increases morbidity and mortality in preterm infants. Early closure of the ductus arteriosus may be achieved pharmacologically or by surgery. The preferred initial treatment of a symptomatic PDA, surgical ligation or treatment with indomethacin, is not clear. OBJECTIVES To compare the effect of surgical ligation of PDA versus medical treatment with cyclooxygenase inhibitors (indomethacin, ibuprofen or mefenamic acid), each used as the initial treatment, on neonatal mortality in preterm infants with a symptomatic PDA. SEARCH METHODS For this update we searched The Cochrane Library 2012, Issue 2, MEDLINE, EMBASE, CINAHL, Clinicaltrials.gov, Controlled-trials.com, Proceedings of the Annual Meetings of the Pediatric Academic Societies (2000 to 2011) (Abstracts2View(TM)) and Web of Science on 8 February 2012. SELECTION CRITERIA Randomised or quasi-randomised trials in preterm or low birth weight neonates with symptomatic PDA and comparing surgical ligation with medical treatment with cyclooxygenase inhibitors, each used as the initial treatment for closure of PDA. DATA COLLECTION AND ANALYSIS The authors independently assessed methodological quality and extracted data for the included trial. We used RevMan 5.1 for analyses of the data. MAIN RESULTS One study reporting on 154 neonates was found eligible. No significant difference between surgical closure and indomethacin treatment was found for in-hospital mortality, chronic lung disease, necrotising enterocolitis, sepsis, creatinine level or intraventricular haemorrhage. There was a significant increase in the surgical group in the incidence of pneumothorax (risk ratio (RR) 2.68; 95% confidence interval (CI) 1.45 to 4.93; risk difference (RD) 0.25; 95% CI 0.11 to 0.38; number needed to treat to harm (NNTH) 4 (95% CI 3 to 9)) and retinopathy of prematurity stage III and IV (RR 3.80; 95% CI 1.12 to 12.93; RD 0.11; 95% CI 0.02 to 0.20; NNTH 9 (95% CI 5 to 50)) compared to the indomethacin group. There was a statistically significant decrease in failure of ductal closure rate in the surgical group as compared to the indomethacin group (RR 0.04; 95% CI 0.01 to 0.27; RD -0.32; 95% CI -0.43 to -0.21, number needed to treat to benefit (NNTB) 3 (95% CI 2 to 4)). No new trials were identified for inclusion in the 2012 update. AUTHORS' CONCLUSIONS There are insufficient data to conclude whether surgical ligation or medical treatment with indomethacin is preferred as the initial treatment for symptomatic PDA in preterm infants.

Abstract
BACKGROUND Successful transition from parenteral nutrition to full enteral feedings during the immediate neonatal period is associated with improved growth in preterm infants. Lactase is the last of the major intestinal disaccharidases to develop in preterm infants. Because of inadequate lactase activity, preterm infants are unable to digest lactose. Lactase preparations could potentially be used to hydrolyse lactose in formulas and breast milk to minimize lactose malabsorption in preterm infants. OBJECTIVES To assess the effectiveness and safety of the addition of lactase to milk compared to placebo or no intervention for the promotion of growth and feeding tolerance in preterm infants. PRIMARY OUTCOMES weight gain expressed as grams/kg/day, growth expressed as weight, length and head circumference percentile for postmenstrual age (PMA), assessed at birth and at 40 weeks PMA, days to achieve full enteral feeds. SECONDARY OUTCOMES several common outcomes associated with preterm birth, and adverse effects. SEARCH METHODS Electronic and manual searches were conducted in January 2005 of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, 2004, Issue 4), MEDLINE (1966 to Jan 2005), EMBASE (1980 to Jan 2005) and CINAHL (1982 to Jan 2005), personal files, bibliographies of identified trials and abstracts by the Pediatric Academic Societies' Meetings and the European Society of Pediatric Research Meetings published in Pediatric Research. The searches were repeated in May 2012 of The Cochrane Library, MEDLINE, EMBASE and CINAHL and abstracts from the Pediatric Academic Societies' Annual Meetings from 2000 to 2012 (Abstracts2View). The Web of Science was searched using the only previously identified trial by Erasmus 2002 as the starting point to search for additional trials that cited this trial. SELECTION CRITERIA Types of studies: randomized or quasi-randomized controlled trials. PARTICIPANTS preterm infants < 37 weeks PMA. INTERVENTION addition of lactase to milk versus placebo or no intervention. DATA COLLECTION AND ANALYSIS The standard methods of the Cochrane Neonatal Review Group were followed independently by the review authors to assess study quality and report outcomes. Treatment effects, calculated using Review Manager 5, included risk ratio (RR), risk difference (RD) and mean difference (MD), all with 95% confidence intervals (CI). A fixed-effect model was used for meta-analyses. We did not perform heterogeneity tests as only one study was identified. MAIN RESULTS The repeat searches conducted in May 2012 did not identify any additional studies for inclusion. One study enrolling 130 infants of 26 to 34 weeks PMA (mean postnatal age at entry 11 days) was identified and no identified study was excluded. The study was a double blind randomized controlled trial of high quality. Lactase treated feeds were initiated when enteral feedings provided > 75% of daily intake. None of the primary outcomes outlined in the protocol for this review and only one of the secondary outcomes, necrotizing enterocolitis (NEC) were reported on. The RR for NEC was 0.32 (95% CI 0.01 to 7.79); the RD was -0.02 (95% CI -0.06 to 0.03) (a reduction which was not statistically significant). There was a statistically significant increase in weight gain at study day 10 in the lactase treated feeds group but not at any other time points. Overall, there was not a statistically significant effect on weight gain. No adverse effects were noted. AUTHORS' CONCLUSIONS The only randomized trial to date provides no evidence of significant benefit to preterm infants from adding lactase to their feeds. Further research regarding effectiveness and safety are required before practice recommendations can be made. Randomized controlled trials comparing lactase versus placebo treated feeds and enrolling infants when enteral feeds are introduced are required. The primary and secondary outcomes for effectiveness and safety should include those identified in this review.

Abstract
BACKGROUND AND OBJECTIVE The "synactive" theory of neurobehavioral development forms the basis of the Newborn Individualized Developmental Care and Assessment Program (NIDCAP). Our objective was to assess the effectiveness of NIDCAP in improving outcomes in preterm infants. METHODS Medline, CINAHL, Embase, PsychInfo, The Cochrane Library, Pediatric Academic Societies' Abstracts and Web of Science were searched in July 2010 and February 2012. The studies selected were randomized controlled trials testing the effectiveness of NIDCAP on medical and neurodevelopmental outcomes. The authors abstracted baseline characteristics of infants and outcomes. The risk of bias was assessed by using Cochrane criteria. RevMan 5.1 was used to synthesize data by the use of relative risk and risk difference for dichotomous outcomes and mean or standardized mean difference for continuous outcomes. RESULTS Eleven primary and 7 secondary studies enrolling 627 neonates were included, with 2 of high quality. The composite primary outcomes of death or major sensorineural disability at 18 months corrected age or later in childhood (3 trials, 302 children; relative risk 0.89 [95% confidence interval 0.61 to 1.29]) and survival free of disability at 18 months corrected age or later in childhood (2 trials, 192 infants; relative risk 0.97 [95% confidence interval 0.69 to 1.35]), were not significantly different between the NIDCAP and control groups. With the sensitivity analysis that excluded the 2 statistically heterogeneous outlying studies, there were no significant differences between groups for short-term medical outcomes. CONCLUSIONS This systematic review including 627 preterm infants did not find any evidence that NIDCAP improves long-term neurodevelopmental or short-term medical outcomes.

Abstract
BACKGROUND Maternal colonization with group B streptococcus (GBS) during pregnancy increases the risk of neonatal infection by vertical transmission. Administration of intrapartum antibiotic prophylaxis (IAP) during labor has been associated with a reduction in early onset GBS disease (EOGBSD). However, treating all colonized women during labor exposes a large number of women and infants to possible adverse effects without benefit. OBJECTIVES To assess the effect of IAP for maternal GBS colonization on neonatal: 1) all cause mortality and 2) morbidity from proven and probable EOGBSD, late onset GBS disease (LOD), maternal infectious outcomes and allergic reactions to antibiotics. SEARCH METHODS We updated the search of the Cochrane Pregnancy and Childbirth Group's Trials Register on 10 November 2012. SELECTION CRITERIA Randomized trials assessing the impact of maternal IAP on neonatal GBS infections were included. DATA COLLECTION AND ANALYSIS We independently assessed eligibility and quality of the studies. MAIN RESULTS We did not identify any new trials from the updated search so the results remain unchanged as follows.Three trials (involving 852 women) evaluating the effects of IAP versus no treatment were included. The risk of bias was high. The use of IAP did not significantly reduce the incidence of all cause mortality, mortality from GBS infection or from infections caused by bacteria other than GBS. The incidence of early GBS infection was reduced with IAP compared to no treatment (risk ratio 0.17, 95% confidence interval (CI) 0.04 to 0.74, three trials, 488 infants; risk difference -0.04, 95% CI -0.07 to -0.01; number needed to treat to benefit 25, 95% CI 14 to 100, I(2) 0%). The incidence of LOD or sepsis from organisms other than GBS and puerperal infection was not significantly different between groups.One trial (involving 352 women) compared intrapartum ampicillin versus penicillin and reported no significant difference in neonatal or maternal outcomes. AUTHORS' CONCLUSIONS Intrapartum antibiotic prophylaxis appeared to reduce EOGBSD, but this result may well be a result of bias as we found a high risk of bias for one or more key domains in the study methodology and execution. There is lack of evidence from well designed and conducted trials to recommend IAP to reduce neonatal EOGBSD.Ideally the effectiveness of IAP to reduce neonatal GBS infections should be studied in adequately sized double-blind controlled trials. The opportunity to conduct such trials has likely been lost, as practice guidelines (albeit without good evidence) have been introduced in many jurisdictions.

Abstract
BACKGROUND Administration of oral sucrose with and without non-nutritive sucking is the most frequently studied non-pharmacological intervention for procedural pain relief in neonates. OBJECTIVES To determine the efficacy, effect of dose and safety of oral sucrose for relieving procedural pain in neonates. SEARCH METHODS We used the standard methods of the Cochrane Neonatal Review Group. Electronic and manual searches were performed in November 2011 for published randomised controlled trials (RCTs) in MEDLINE (1950 to November 2011), EMBASE (1980 to 2011), CINAHL (1982 to November 2011) and the Cochrane Central Register of Controlled Trials (The Cochrane Library). We did not impose language restrictions. SELECTION CRITERIA RCTs in which term, preterm, or both term and preterm neonates (postnatal age maximum of 28 days after reaching 40 weeks' postmenstrual age) received sucrose for procedural pain. Control conditions included no treatment, water, pacifier, positioning/containing or breastfeeding. DATA COLLECTION AND ANALYSIS Main outcome measures were physiological, behavioural, or both pain indicators with or without composite pain scores. A mean difference (MD) with 95% confidence intervals (CI) using the fixed-effect model was reported for continuous outcome measures. Trial quality was assessed as per The Cochrane Collaboration MAIN RESULTS Fifty-seven studies enrolling 4730 infants were included. Results from only a few studies could be combined in meta-analyses. When Premature Infant Pain Profile (PIPP) scores were pooled, sucrose groups had significantly lower scores at 30 seconds (weighted mean difference (WMD) -1.76; 95% CI -2.54 to - 0.97; 4 trials; 264 neonates] and 60 seconds (WMD -2.05; 95% CI -3.08 to -1.02; 3 trials' 195 neonates) post-heel lance. For retinopathy of prematurity (ROP) examinations, sucrose did not significantly reduce PIPP scores (WMD -0.65; 95% CI -1.88 to 0.59; 3 trials; 82 neonates). There were no differences in adverse effects between sucrose and control groups. Sucrose significantly reduced duration of total crying time (WMD -39 seconds; 95% CI -44 to -34; 2 trials; 88 neonates), but did not reduce duration of first cry during heel lance (WMD -9 seconds; 95% CI -20 to 2; 3 trials; 192 neonates). Oxygen saturation (%) was significantly lower in infants given sucrose during ROP examination compared to controls (WMD -2.6; 95% CI -4.9 to - 0.2; 2 trials; 62 neonates). Results of individual trials that could not be incorporated in meta-analyses supported these findings. The effects of sucrose on long-term neurodevelopmental outcomes are unknown. AUTHORS' CONCLUSIONS Sucrose is safe and effective for reducing procedural pain from single events. An optimal dose could not be identified due to inconsistency in effective sucrose dosage among studies. Further investigation on repeated administration of sucrose in neonates and the use of sucrose in combination with other non-pharmacological and pharmacological interventions is needed. Sucrose use in extremely preterm, unstable, ventilated (or a combination of these) neonates needs to be addressed. Additional research is needed to determine the minimally effective dose of sucrose during a single painful procedure and the effect of repeated sucrose administration on immediate (pain intensity) and long-term (neurodevelopmental) outcomes.

Abstract
BACKGROUND Low plasma levels of erythropoietin (EPO) in preterm infants provide a rationale for the use of EPO to prevent or treat anaemia. OBJECTIVES To assess the effectiveness and safety of early versus late initiation of EPO in reducing red blood cell (RBC) transfusions in preterm and/or low birth weight (LBW) infants. SEARCH METHODS The standard search of the Cochrane Neonatal Review Group (CNRG) was performed in 2006 and updated in 2009. Updated search in September 2009 as follows: The Cochrane Library, MEDLINE (search via PubMed), CINAHL and EMBASE were searched from 2005 to September 2009. The searches were repeated in March 2012. The Pediatric Academic Societies' Annual meetings were searched electronically from 2000 to 2012 at Abstracts2View(TM) as were clinical trials registries (clinicaltrials.gov; controlled-trials.com; and who.int/ictrp). SELECTION CRITERIA Randomised or quasi-randomised controlled trials enrolling preterm or LBW infants less than eight days of age. INTERVENTION Early initiation of EPO (initiated at less than eight days of age) versus late initiation of EPO (initiated at eight to 28 days of age). DATA COLLECTION AND ANALYSIS The standard methods of the CNRG were followed. Weighted treatment effects included typical risk ratio (RR), typical risk difference (RD), number needed to treat to benefit (NNTB), number needed to treat to harm (NNTH) and mean difference (MD), all with 95% confidence intervals (CI). A fixed-effect model was used for meta-analyses and heterogeneity was evaluated using the I-squared (I(2)) test. MAIN RESULTS No new trials were identified in March of 2012. Two high quality randomised double-blind controlled studies enrolling 262 infants were identified. A non-significant reduction in the 'Use of one or more RBC transfusions' [two studies 262 infants; typical RR 0.91 (95% CI 0.78 to 1.06); typical RD -0.07 (95% CI -0.18 to 0.04; I(2) = 0% for both RR and RD] favouring early EPO was noted. Early EPO administration resulted in a non-significant reduction in the "number of transfusions per infant" compared with late EPO [typical MD - 0.32 (95% CI -0.92 to 0.29)]. There was no significant reduction in total volume of blood transfused per infant or in the number of donors to whom the infant was exposed. Early EPO led to a significant increase in the risk of retinopathy of prematurity (ROP) (all stages) [two studies, 191 infants; typical RR 1.40 (95% CI 1.05 to 1.86); typical RD 0.16 (95% CI 0.03 to 0.29); NNTH 6 (95% CI 3 to 33)]. There was high heterogeneity for this outcome (I(2) = 86% for RR and 81% for RD). Both studies (191 infants) reported on ROP stage ≥ 3. No statistically significant increase in risk was noted [typical RR 1.56 (95% CI 0.71 to 3.41); typical RD 0.05 (-0.04 to 0.14)] There was no heterogeneity for this outcome (0% for both RR and RD). No other important favourable or adverse neonatal outcomes or side effects were reported. AUTHORS' CONCLUSIONS The use of early EPO did not significantly reduce the 'Use of one or more RBC transfusions' or the 'Number of transfusions per infant" compared with late EPO administration. The finding of a statistically significant increased risk of ROP (any grade) and a similar trend for ROP stage ≥ 3 with early EPO treatment is of great concern.

Abstract
OBJECTIVE To examine the association between treatment for patent ductus arteriosus (PDA) and neonatal outcomes in preterm infants, after adjustment for treatment selection bias. STUDY DESIGN Secondary analyses were conducted using data collected by the Canadian Neonatal Network for neonates born at a gestational age ≤ 32 weeks and admitted to neonatal intensive care units in Canada between 2004 and 2008. Infants who had PDA and survived beyond 72 hours were included in multivariable logistic regression analyses that compared mortality or any severe neonatal morbidity (intraventricular hemorrhage grades ≥ 3, retinopathy of prematurity stages ≥ 3, bronchopulmonary dysplasia, or necrotizing enterocolitis stages ≥ 2) between treatment groups (conservative management, indomethacin only, surgical ligation only, or both indomethacin and ligation). Propensity scores (PS) were estimated for each pair of treatment comparisons, and used in PS-adjusted and PS-matched analyses. RESULTS Among 3556 eligible infants with a diagnosis of PDA, 577 (16%) were conservatively managed, 2026 (57%) received indomethacin only, 327 (9%) underwent ligation only, and 626 (18%) were treated with both indomethacin and ligation. All multivariable and PS-based analyses detected significantly higher mortality/morbidities for surgically ligated infants, irrespective of prior indomethacin treatment (OR ranged from 1.25-2.35) compared with infants managed conservatively or those who received only indomethacin. No significant differences were detected between infants treated with only indomethacin and those managed conservatively. CONCLUSIONS Surgical ligation of PDA in preterm neonates was associated with increased neonatal mortality/morbidity in all analyses adjusted for measured confounders that attempt to account for treatment selection bias.

Abstract
BACKGROUND Low plasma levels of erythropoietin (EPO) in preterm infants provide a rationale for the use of EPO to prevent or treat anaemia. OBJECTIVES To assess the effectiveness and safety of late initiation of EPO (initiated at eight days after birth or later) in reducing the use of red blood cell (RBC) transfusions in preterm and/or low birth weight infants. SEARCH METHODS For this update MEDLINE, EMBASE, CINAHL, and The Cochrane Library were searched in March 2012. Additional searches included the Pediatric Academic Societies Annual Meetings from 2000 to 2012 (Abstracts2 View(TM)) and clinical trials registries (clinicaltrials.gov; controlled-trials.com; and who.int/ictrp). SELECTION CRITERIA Randomised or quasi-randomised controlled trials of late initiation of EPO treatment (started at ≥ eight days of age) versus placebo or no intervention in preterm (< 37 weeks) and/or low birth weight (< 2500 g) neonates. DATA COLLECTION AND ANALYSIS Data collection and analyses were performed in accordance with the methods of the Cochrane Neonatal Review Group. MAIN RESULTS In this 2012 update one new study for inclusion was identified. Twenty-eight studies enrolling 1361 preterm infants in 21 countries were included. Most trials were of small sample size. The meta-analysis showed a significant effect on the use of one or more RBC transfusions [typical risk ratio (RR); 0.66 (95% confidence interval (CI); 0.59 to 0.74); typical risk difference (RD) -0.21 (95% CI; -0.26 to -0.16); typical number needed to benefit (NNTB) of 5 (95% CI 4 to 6) 19 studies, 912 infants]. There was moderate heterogeneity for this outcome [for RR (P < 0.00001; I(2) = 74.0%); for RD (P = 0.0006; I(2) = 58.9%)]. Similar results were obtained in secondary analyses based on different combinations of high/low doses of EPO and iron supplementation. In this update there was no significant reduction in the total volume (mL/kg) of blood transfused per infant [typical MD -1.61mL/kg (95% CI -5.78 to 2.57); 5 studies, 197 infants] There was high heterogeneity for this outcome (P = 0.00001, I(2) = 92%). There was a significant reduction in the number of transfusions per infant (nine studies enrolling 567 infants); [typical MD -0.78 (-0.97 to -0.59)]. Three studies including 331 patients reported on retinopathy of prematurity (ROP) (all stages), with a typical RR 0.79 (95% CI 0.57 to 1.10) and a typical RD of -0.05 (95% CI -0.13 to 0.02). This outcome was not statistically significantly different between the groups. There was no heterogeneity for this outcome for either RR (P = 0.41; I(2) = 0%) or RD (P = 0.43; I(2) = 0%). Two trials enrolling 212 patients reported on severe ROP (stage 3 or greater). The typical RR was 0.83 (95% CI 0.23 to 2.98) and the typical RD was -0.01 (95% CI -0.06 to 0.05); neither were statistically significant. There was no heterogeneity for this outcome for either RR (P = 0.29; I(2) = 9.3%) or RD (P = 0.36; I(2) = 0%).There were no significant differences in other clinical outcomes. Long-term neurodevelopmental outcomes were not reported. AUTHORS' CONCLUSIONS Late administration of EPO reduces the use of one or more RBC transfusions, the number of RBC transfusions per infant but not the total volume of RBCs transfused per infant. Any donor exposure is likely not avoided as most studies included infants who had received RBC transfusions prior to trial entry. Late EPO does not significantly reduce or increase any clinically important adverse outcomes. Further research of the use of late EPO treatment to prevent donor exposure is not indicated. Research efforts should focus on limiting donor exposure during the first few days of life in sick neonates, when RBC requirements are most likely to be required and cannot be prevented by late EPO treatment.

Abstract
BACKGROUND Low plasma levels of erythropoietin (EPO) in preterm infants provide a rationale for the use of EPO to prevent or treat anaemia. OBJECTIVES To assess the effectiveness and safety of early initiation of EPO in reducing red blood cell (RBC) transfusions in preterm and/or low birth weight infants. SEARCH METHODS The Cochrane Central Register of Controlled Trials (The Cochrane Library), MEDLINE, EMBASE, CINAHL, abstracts from scientific meetings published in Pediatric Research and reference lists of identified trials and reviews were searched through July 2009. Searches were repeated in March 2012 including searches of Pediatric Academic Societies Annual meetings 2000 to 2012 (Abstracts2View(TM)) and clinical trials registries (clinicaltrials.gov; controlled-trials.com; and who.int/ictrp). SELECTION CRITERIA Randomised or quasi-randomised controlled trials of early (< eight days of age) initiation of EPO treatment versus placebo or no intervention in preterm and/or low birth weight neonates. DATA COLLECTION AND ANALYSIS Data collection and analysis were accomplished using the methods of the Neonatal Cochrane Review Group. MAIN RESULTS The May 2012 update did not identify any new studies for inclusion. A number of randomised controlled trials were excluded as they compared one EPO dosing regimen with another, did not provide the numbers of infants randomised to the EPO and the placebo group, or the dose of EPO was not stated. The update includes 27 studies that enrolled 2293 preterm infants. Early EPO reduced the risk of the "use of one or more RBC transfusions" [typical risk ratio (RR); 0.80 (95% confidence interval (CI) 0.75 to 0.86); typical risk difference (RD) -0.13, (95% CI -0.17 to -0.09); number needed to benefit (NNTB) = eight, (95% CI 6 to 11); 16 studies, 1,825 infants].There was moderate heterogeneity for this outcome [RR (P = 0.004; I(2) = 56.7%); RD (P = 0.003; I(2) = 56.0%)].A total of six studies enrolling 515 infants reported on the total volume of red blood cells transfused per infant. The significant typical mean difference (MD) was a reduction of 6 mL/kg of blood transfused (mL/kg) per infant (95% CI -11 to - 1). There was moderate heterogeneity for this outcome (P = 0.02; I(2) = 63.0%). The results from 14 studies enrolling 1131 infants reported on the number of red blood cell transfusions per infant. The significant typical MD for number of red blood cell transfusions per infant was -0.33, (95% CI -0.48 to -0.18). There was high heterogeneity for this outcome (P = 0.00001, I(2) = 78%). Two studies enrolling 188 infants reported on the number of donors to whom the infant was exposed; the MD was significantly reduced -0.63, (-1.07 to -0.19). There was no heterogeneity for this outcome (P = 0.59; I(2) = 0%).There was a significant increase in the risk of stage ≥ 3 retinopathy of prematurity (ROP) in the early EPO group [typical RR; 1.65, (95% CI 1.12 to 2.43); typical RD; 0.05 (95% CI 0.01 to 0.08); number needed to harm (NNTH); 20, (95% CI 13 to 100); eight studies, 984 infants]. There was no heterogeneity for this outcome for RR (P = 0.87; I(2) = 0%), but there was moderate heterogeneity for RD (P = 0.006; I(2) = 65%). The rates for mortality and other neonatal morbidities were not significantly changed by early EPO treatment nor were neurodevelopmental outcomes at 18 to 22 months in the small number of infants tested to-date. AUTHORS' CONCLUSIONS Early administration of EPO reduces the use of RBC transfusions and the volume of RBCs transfused. These small reductions are of limited clinical importance. Donor exposure is probably not avoided since most studies included infants who had received RBC transfusions prior to trial entry. There was a significant increase in the rate of ROP (stage ≥ 3). Early EPO does not significantly decrease or increase any of the other important adverse outcomes. Ongoing research should deal with the issue of ROP and evaluate the current clinical practice that will limit donor exposure. Due to the limited benefits and the increased risk of ROP, early administration of EPO is not recommended. Evidence is lacking for the possible neuro protective role of EPO in preterm infants. This topic will be reviewed in separate Cochrane reviews for preterm and term and late preterm infants.

Abstract
BACKGROUND Neonatal meningitis may be caused by bacteria, especially gram-negative bacteria, which are difficult to eradicate from the cerebrospinal fluid (CSF) using safe doses of antibiotics. In theory, intraventricular administration of antibiotics would produce higher antibiotic concentrations in the CSF than intravenous administration alone, and eliminate the bacteria more quickly. However, ventricular taps may cause harm. OBJECTIVES To assess the effectiveness and safety of intraventricular antibiotics (with or without intravenous antibiotics) in neonates with meningitis (with or without ventriculitis) as compared to treatment with intravenous antibiotics alone. SEARCH METHODS The Cochrane Library, Issue 2, 2007; MEDLINE; EMBASE; CINAHL and Science Citation Index were searched in June 2007. The Oxford Database of Perinatal Trials was searched in June 2004. Pediatric Research (abstracts of proceedings) were searched (1990 to April 2007) as were reference lists of identified trials and personal files. No language restrictions were applied.This search was updated in May 2011. SELECTION CRITERIA Selection criteria for study inclusion were: randomised or quasi-randomised controlled trials in which intraventricular antibiotics with or without intravenous antibiotics were compared with intravenous antibiotics alone in neonates (< 28 days old) with meningitis. One of the following outcomes was required to be reported: mortality during initial hospitalisation; neonatal or infant mortality, or both; neurodevelopmental outcome; duration of hospitalisation; duration of culture positivity of CSF and side effects. DATA COLLECTION AND ANALYSIS All review authors abstracted information for outcomes reported and one review author checked for discrepancies and entered data into RevMan 5.1. Risk ratio (RR), risk difference (RD), number needed to treat for an additional beneficial outcome (NNTB) or number needed to treat for an additional harmful outcome (NNTH), and mean difference (MD), using the fixed-effect model are reported with 95% confidence intervals (CI). MAIN RESULTS The updated search in June 2011 did not identify any new trials. One study is included in the review. This study assessed the effect of intraventricular gentamicin in a mixed population of neonates (69%) and older infants (31%) with gram-negative meningitis and ventriculitis. Mortality was statistically significantly higher in the group that received intraventricular gentamicin in addition to intravenous antibiotics compared to the group receiving intravenous antibiotics alone (RR 3.43; 95% CI 1.09 to 10.74; RD 0.30; 95% CI 0.08 to 0.53); NNTH 3; 95% CI 2 to 13). Duration of CSF culture positivity did not differ significantly (MD -1.20 days; 95% CI -2.67 to 0.27). AUTHORS' CONCLUSIONS In one trial that enrolled infants with gram-negative meningitis and ventriculitis, the use of intraventricular antibiotics in addition to intravenous antibiotics resulted in a three-fold increased RR for mortality compared to standard treatment with intravenous antibiotics alone. Based on this result, intraventricular antibiotics as tested in this trial should be avoided. Further trials comparing these interventions are not justified in this population.

Abstract
BACKGROUND In the 1960s and 1970s, pulmonary haemorrhage (PH) occurred mainly in full-term infants with pre-existing illness with an incidence of 1.3 per 1000 live births. Risk factors for PH included severity of illness, intrauterine growth restriction, patent ductus arteriosus (PDA), coagulopathy and the need for assisted ventilation. Presently, PH occurs in 3% to 5% of preterm ventilated infants with severe respiratory distress syndrome (RDS) who often have a PDA and have received surfactant. The cause of PH is thought to be due to rapid lowering of intrapulmonary pressure, which facilitates left to right shunting across a PDA and an increase in pulmonary blood flow. Retrospective case reports and one prospective uncontrolled study have shown promising results for surfactant in treating PH. OBJECTIVES To evaluate the effect of surfactant treatment compared to placebo or no intervention on mortality and morbidities in neonates with PH. SEARCH METHODS For this update The Cochrane Library, Issue 2, 2012; MEDLINE; EMBASE; CINAHL; Clinicaltrials.gov; Controlled-trials.com; proceedings (2000 to 2011) of the Annual Meetings of the Pediatric Academic Societies (Abstracts2View) and Web of Science were searched on 8 February 2012. SELECTION CRITERIA Randomised or quasi-randomised controlled trials that evaluated the effect of surfactant in the treatment of PH in intubated term or preterm (< 37 weeks) neonates with PH. Infants were included up to 44 weeks' postmenstrual age. The interventions studied were intratracheal instillation of surfactant (natural or synthetic, regardless of dose) versus placebo or no intervention. DATA COLLECTION AND ANALYSIS If studies were identified by the literature search, the planned analyses included risk ratio, risk difference, number needed to treat to benefit or to harm for dichotomous outcomes, and mean difference for continuous outcomes, with their 95% confidence intervals. A fixed-effect model would be used for meta-analyses. The risk of bias for included trials would be assessed. Heterogeneity tests, including the I(2) statistic, would be performed to assess the appropriateness of pooling the data and the results would be reported. MAIN RESULTS No trials were identified. AUTHORS' CONCLUSIONS No randomised or quasi-randomised trials that evaluated the effect of surfactant in PH were identified. Therefore, no conclusions from such trials can be drawn. In view of the promising results from studies with less strict study designs than a randomised controlled trial, there is reason to conduct further trials of surfactant for the treatment of PH in neonates.

Abstract
BACKGROUND Proper sedation for neonates undergoing uncomfortable procedures may reduce stress and avoid complications. Midazolam is a short-acting benzodiazepine that is increasingly used in neonatal intensive care units (NICU). However, its effectiveness as a sedative in neonates has not been systematically evaluated. OBJECTIVES To determine whether intravenous midazolam infusion is an effective sedative, as evaluated by behavioural or physiological measurements, or both, for critically ill neonates undergoing intensive care and to assess clinically significant short- and long-term adverse effects associated with its use. SEARCH METHODS We performed a literature search according to the Cochrane Neonatal Review Group search strategy. Randomised and quasi-randomised controlled trials of intravenous midazolam use in neonates were identified by searching the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2012), MEDLINE (1985 to 2012), EMBASE (1980 to 2012), CINAHL (1981 to 2012), reference lists of published studies, personal files, and abstracts published in The Pediatric Academic Societies Meeting Abstract Archives from 1990 to 2011. SELECTION CRITERIA Randomised and quasi-randomised controlled trials of intravenous midazolam infusion in infants aged 28 days or less for sedation were selected for review. DATA COLLECTION AND ANALYSIS Data regarding the primary outcome of level of sedation were abstracted. Secondary outcomes such as intraventricular haemorrhage (IVH), periventricular leukomalacia (PVL), death, length of NICU stay, and adverse effects associated with midazolam were assessed. When appropriate, meta-analyses were performed using risk ratio (RR), risk difference (RD), along with their 95% confidence intervals (95% CI) for categorical variables and weighted mean difference (WMD) for continuous variables. MAIN RESULTS Three trials were included in the review. Using different sedation scales, each study showed a statistically significantly higher sedation level in the midazolam group compared to the placebo group. However, since none of the sedation scales used have been validated in preterm infants, the effectiveness of midazolam in this population could not be ascertained. One study showed a statistically significant higher incidence of adverse neurological events (death, grade III or IV IVH, PVL), and meta-analysis of data from two studies showed a statistically significant longer duration of NICU stay in the midazolam group compared to the placebo group. AUTHORS' CONCLUSIONS There are insufficient data to promote the use of intravenous midazolam infusion as a sedative for neonates undergoing intensive care. This review raises concerns about the safety of midazolam in neonates. Further research on the effectiveness and safety of midazolam in neonates is needed.

Abstract
BACKGROUND Chronic lung disease (CLD) frequently occurs in preterm infants and has a multifactorial aetiology including inflammation. Cromolyn sodium is a mast cell stabiliser that inhibits neutrophil activation and neutrophil chemotaxis and may, therefore, have a role in the prevention of CLD. OBJECTIVES To determine the effect of prophylactic administration of cromolyn sodium on the incidence of CLD, mortality or the combined outcome of mortality or CLD at 28 days of life in preterm infants at risk of CLD. SEARCH METHODS The search strategy of the Cochrane Neonatal Review Group was used to identify studies. Searches were made of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2009), MEDLINE, EMBASE, CINAHL up to and including July 2009, personal files and reference lists of identified trials. For this update the same data bases were searched on 12 April 2012. In addition, on the same date, abstracts from the Pediatric Academic Societies' Annual Meetings (2000 to 2012) were searched on the website PAS2View(TM) as was the Web of Science website using the two previously identified trials as starting points. SELECTION CRITERIA Randomised or quasi-randomised controlled clinical trials involving preterm infants. Initiation of cromolyn sodium administration during the first two weeks of life. The intervention had to include administration of cromolyn sodium by nebuliser or metered dose inhaler with or without spacer device versus placebo or no intervention. Eligible studies had to include at least one of the following outcomes: overall mortality, CLD at 28 days, CLD at 36 weeks' postmenstrual age (PMA), or the combined outcome mortality or CLD at 28 days. DATA COLLECTION AND ANALYSIS The standard method for The Cochrane Collaboration as described in the Cochrane Handbook for Systematic Reviews of Interventions was used. Risk ratio (RR) and risk difference (RD) with 95% confidence intervals (CI) are reported for dichotomous outcomes and weighted mean difference (WMD) for continuous data. A fixed-effect model was used for meta-analysis. Heterogeneity was examined using the I(2) statistic. MAIN RESULTS Two eligible studies were identified with small numbers of infants enrolled. Prophylaxis with cromolyn sodium did not result in a statistically significant effect on the combined outcome of mortality or CLD at 28 days; CLD at 28 days or at 36 weeks' PMA; or CLD in survivors at 28 days or at 36 weeks' PMA. Prophylaxis with cromolyn sodium did not show a statistically significant difference in overall neonatal mortality, incidence of air leaks, necrotising enterocolitis, intraventricular haemorrhage, sepsis, and days of mechanical ventilation. No side effects were noted. Further research does not seem to be justified. AUTHORS' CONCLUSIONS There is currently no evidence from randomised trials that cromolyn sodium has a role in the prevention of CLD. Cromolyn sodium cannot be recommended for the prevention of CLD in preterm infants.

Abstract
BACKGROUND Chronic lung disease (CLD) occurs frequently in preterm infants. Bronchodilators have the potential effect of dilating small airways with muscle hypertrophy. Increase in compliance and tidal volume and decrease in pulmonary resistance have been documented with use of bronchodilators in studies of pulmonary mechanics in infants with CLD. Therefore, it is possible that bronchodilators might have a role in the prevention and treatment of CLD. OBJECTIVES To determine the effect of bronchodilators given either prophylactically or as treatment for CLD on mortality and other complications of prematurity in preterm infants at risk for or having CLD. SEARCH METHODS For this update of the review, searches of The Cochrane Library, Issue 3, 2012; MEDLINE 1966; EMBASE; CINAHL; personal files and reference lists of identified trials were performed in March 2012. In addition Web of Science and abstracts from the Annual meetings of the Pediatric Academic Societies were searched electronically from 2000 to 2012 on PAS Abstracts2view(TM.) No language restrictions were applied. SELECTION CRITERIA Randomised controlled trials involving preterm infants were eligible for inclusion. Initiation of bronchodilator therapy had to occur within two weeks of birth for prevention of CLD. For treatment of CLD, treatment had to be initiated before discharge from the neonatal unit. The intervention had to include the administration of a bronchodilator either by nebulisation, metered dose inhaler (with or without a spacer device), intravenously or orally versus placebo or no intervention. Eligible studies had to include at least one of the predefined clinical outcomes (mortality, CLD, number of days on oxygen, number of days on ventilator, patent ductus arteriosus (PDA), pulmonary interstitial emphysema (PIE), pneumothorax, any grade of intraventricular haemorrhage (IVH), necrotising enterocolitis (NEC), sepsis and adverse effects of bronchodilators. Adverse effects of bronchodilators included hypokalaemia, tachycardia, cardiac arrhythmias, tremor, hypertension and hyperglycaemia). DATA COLLECTION AND ANALYSIS We used the standard method described in the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2011). Two investigators extracted and assessed all data for each study. We reported risk ratio (RR) and risk difference (RD) with 95% confidence intervals (CI) for dichotomous outcomes and weighted mean difference (WMD) for continuous data. MAIN RESULTS In this update we identified four randomised controlled trials investigating the effects of bronchodilators in preterm infants. None of these studies fulfilled our inclusion criterion that clinical outcomes should be reported. One eligible study was previously found dealing with prevention of CLD; this study used salbutamol and enrolled 173 infants. No eligible studies were found dealing with treatment of CLD. Prophylaxis with salbutamol did not show a statistically significant difference in mortality (RR 1.08; 95% CI 0.50 to 2.31; RD 0.01; 95% CI -0.09 to 0.11) or CLD (RR 1.03; 95% CI 0.78 to 1.37; RD 0.02; 95% CI -0.13 to 0.17). No statistically significant differences were seen in other complications associated with CLD or preterm birth. No side effects due to salbutamol were commented on in this study. AUTHORS' CONCLUSIONS There are insufficient data to reliably assess the use of salbutamol for the prevention of CLD. Further clinical trials are necessary to assess the role of salbutamol or other bronchodilator agents in prophylaxis or treatment of CLD. Researchers studying the effects of bronchodilators in preterm infants should include relevant clinical outcomes in addition to pulmonary mechanical outcomes.

Abstract
The Canadian Neonatal Network conducted a trial of Evidence-Based Practice for Improving Quality (EPIQ) between 2002 and 2005. Improved neonatal intensive care unit (NICU) outcomes established credibility for quality improvement. We surveyed team members and physician leaders to examine critical success factors and barriers to improvement during EPIQ. Respondents agreed that EPIQ had a high utility, was effectively implemented and was a major learning opportunity. The collaborative nature of the project was key to success. Respondents identified the need for additional training and resources in quality improvement. Better communication between clinicians and senior leaders is required to support quality improvement in NICUs.

Abstract
BACKGROUND Chronic lung disease remains a common complication among preterm infants. There is increasing evidence that inflammation plays an important role in the pathogenesis of CLD. Due to their strong anti-inflammatory properties, corticosteroids are an attractive intervention strategy. However, there are growing concerns regarding short and long-term effects of systemic corticosteroids. Theoretically, administration of inhaled corticosteroids may allow for beneficial effects on the pulmonary system with a lower risk of undesirable systemic side effects. OBJECTIVES To determine the impact of inhaled corticosteroids administered to ventilated very low birth weight preterm neonates in the first two weeks of life for the prevention of chronic lung disease (CLD). SEARCH METHODS Randomised and quasi-randomised trials were identified by searching the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2007), MEDLINE (1966 to July 2007), EMBASE (1980 to July 2007), CINAHL (1982 to July 2007), reference lists of published trials and abstracts published in Pediatric Research or electronically on the Pediatric Academic Societies web-site (1990 to April 2007).This search was updated in 2011. SELECTION CRITERIA Randomised controlled trials of inhaled corticosteroid therapy initiated within the first two weeks of life in ventilated preterm infants with birth weight <1500 grams were included in this review. DATA COLLECTION AND ANALYSIS Data regarding clinical outcomes including chronic lung disease at 28 days or 36 weeks postmenstrual age (PMA), mortality, combined outcome of death or CLD at 28 days of age and at 36 weeks PMA, the need for systemic corticosteroids, failure to extubate within 14 days and adverse effects of corticosteroids were evaluated. All data were analysed using RevMan 4.2.10. When possible, meta-analysis was performed using relative risk (RR), risk difference (RD), along with their 95% confidence intervals (CI). If RD was significant, the number needed to treat (NNT) was calculated. MAIN RESULTS One ongoing trial was identified for inclusion in this update. Eleven trials assessing the impact of inhaled corticosteroid for the prevention of CLD were identified. Four trials were excluded. The present review includes data analyses based on seven qualifying trials. There was no statistically significant effect of inhaled steroids on CLD either at 28 days [typical RR 1.05 (95% CI 0.84 to 1.32); typical RD 0.02 (95% CO -0.07 to 0.11)] or at 36 weeks PMA [typical RR 0.97 (95% CI 0.62 to 1.52); typical RD 0.00 (95% CI -0.07, 0.06)], when analysed either for all randomised infants or among survivors. No statistically significant differences were noted for mortality or for the combined outcome of mortality and CLD either at 28 days of age or at 36 weeks PMA. There were no statistically significant differences in adverse events between groups. AUTHORS' CONCLUSIONS Based on this updated review, there is no evidence from the trials reviewed that early administration (in the first two weeks of life) of inhaled steroids to ventilated preterm neonates was effective in reducing the incidence of CLD. Currently, use of inhaled steroids in this population cannot be recommended. Studies are needed to identify the risk/benefit ratio of different delivery techniques and dosing schedules for the administration of these medications. Studies need to address both the short-term and long-term benefits and adverse effects of inhaled steroids with particular attention to neurodevelopmental outcome.

Abstract
BACKGROUND Chronic lung disease (CLD) remains a serious and common problem among very low birth weight (VLBW) infants despite the use of antenatal steroids and postnatal surfactant therapy to decrease the incidence and severity of respiratory distress syndrome. Due to their anti-inflammatory properties, corticosteroids have been widely used to treat or prevent CLD. However, the use of systemic steroids has been associated with serious short and long-term adverse effects. Administration of corticosteroids topically through the respiratory tract might result in beneficial effects on the pulmonary system with fewer undesirable systemic side effects. OBJECTIVES To determine the effect of inhaled versus systemic corticosteroids administered to ventilator dependent preterm neonates with birth weight < 1500 g or gestational age < 32 weeks after two weeks of life for the treatment of evolving CLD. SEARCH METHODS Randomised and quasi-randomised trials were identified by searching the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2007), MEDLINE (1966 to June 2007), EMBASE (1980 to June 2007), CINAHL (1982 to June 2007), reference lists of published trials and abstracts published in Pediatric Research or electronically on the Pediatric Academic Societies web site (1990 to April 2007). This search was updated in June 2011 and included additional searches of Clinicaltrials.gov, Controlled-trials.com and Web of Science. SELECTION CRITERIA Randomised or quasi-randomised trials comparing inhaled versus systemic corticosteroid therapy (irrespective of the dose and duration of therapy) starting after the first two weeks of life in ventilator dependent VLBW infants. DATA COLLECTION AND ANALYSIS Data were extracted regarding clinical outcomes and were analysed using Review Manager. When appropriate, meta-analysis was performed using relative risk (RR), risk difference (RD), and weighted mean difference (WMD) along with their 95% confidence intervals (CI). If RD was statistically significant, the number needed to benefit (NNTB) or the number needed to harm (NNTH) was calculated. MAIN RESULTS Five trials comparing inhaled versus systemic corticosteroids in the treatment of CLD were identified. Two trials were excluded as both included non-ventilator dependent patients and three trials qualified for inclusion in this review. No new trials were identified in the 2011 update.Halliday et al (Halliday 2001) randomised infants at < 72 hours (n = 292), while Rozycki et al (Rozycki 2003) and Suchomski et al (Suchomski 2002) randomised at 12 to 21 days. The data from the two trials of Rozycki et al and Suchmoski et al are combined using meta-analytic techniques. The data from the trial by Halliday et al are reported separately, as outcomes were measured over different time periods from the age at randomisation.In none of the trials was there a statistically significant difference between the groups in the incidence of CLD at 36 weeks PMA among all randomised infants. The estimates for the trial by Halliday et al (Halliday 2001) were RR 1.10 (95% CI 0.82 to 1.47), RD 0.03 (95% CI -0.08 to 0.15).For the trials by Rozycki et al (Rozycki 2003) and Suchomski et al (Suchomski 2002) the typical RR was 1.02 (95% CI 0.83 to 1.25) and the typical RD 0.01 (95% CI -0.11 to 0.14); (number of infants = 139 ). There were no statistically significant differences between the groups in either trial for oxygen dependency at 28 days of age, death by 28 days or 36 weeks PMA, the combined outcome of death by or CLD at 28 days or 36 weeks PMA, duration of intubation, duration of oxygen dependence, or adverse effects. Information on the long-term neurodevelopmental outcomes was not available. AUTHORS' CONCLUSIONS This review found no evidence that inhaled corticosteroids confer net advantages over systemic corticosteroids in the management of ventilator dependent preterm infants. Neither inhaled steroids nor systemic steroids can be recommended as standard treatment for ventilated preterm infants. There was no evidence of difference in effectiveness or side-effect profiles for inhaled versus systemic steroids. A better delivery system guaranteeing selective delivery of inhaled steroids to the alveoli might result in beneficial clinical effects without increasing side-effects. To resolve this issue, studies are needed to identify the risk/benefit ratio of different delivery techniques and dosing schedules for the administration of these medications. The long-term effects of inhaled steroids, with particular attention to neurodevelopmental outcome, should be addressed in future studies.

Abstract
BACKGROUND Chronic lung disease (CLD) remains an important cause of mortality and morbidity in preterm infants and inflammation plays an important role in its pathogenesis. The use of inhaled corticosteroids may modulate the inflammatory process without concomitant high systemic steroid concentrations and less risk of adverse effects. OBJECTIVES To determine the effect of inhaled versus systemic corticosteroids started within the first two weeks of life on preventing CLD in ventilated very low birth weight (VLBW) infants. SEARCH METHODS Randomised and quasi-randomised trials were identified by searching The Cochrane Library, MEDLINE , EMBASE , CINAHL, reference lists of published trials and abstracts published in Pediatric Research or electronically on the Pediatric Academic Societies web site in June 2007.This search was updated in June 2011 and included additional searches of Clinicaltrials.gov, Controlled-trials.com and Web of Science. SELECTION CRITERIA Randomised or quasi-randomised clinical trials comparing inhaled versus systemic corticosteroid therapy (regardless of the dose and duration of therapy) started in the first two weeks of life in VLBW infants receiving assisted ventilation. DATA COLLECTION AND ANALYSIS Outcomes including CLD at 28 days or 36 weeks postmenstrual age (PMA), mortality, the combined outcome of death or CLD at 28 days or 36 weeks PMA, other pulmonary outcomes and adverse effects were evaluated. All data were analysed using RevMan 5.1. Meta-analyses were performed using relative risk (RR), risk difference (RD), and mean difference (MD) with their 95% confidence intervals (CI). If RD was significant, the numbers needed to benefit (NNTB) or to harm (NNTH) were calculated. MAIN RESULTS No new trials were identified in this update. Two trials qualified for inclusion in this review. The incidence of CLD at 36 weeks PMA was increased (of borderline statistical significance) in the inhaled steroid group [RR 1.45 (95% CI 0.99 to 2.11); RD 0.11 (95% CI 0.00 to 0.21), p = 0.05, one trial, n = 278]. The incidence of CLD at 36 weeks PMA among all survivors [RR 1.34 (95% CI 0.94 to 1.90); RD 0.11 (95% CI -0.02 to 0.24), one trial, n = 206], oxygen dependency at 28 days (two trials, n = 294), death by 28 days (two trials, n = 294) or 36 weeks PMA (two trials, n = 294) and the combined outcome of death or CLD by 28 days (two trials, n = 294) or 36 weeks PMA (one trial, n = 278) did not differ significantly between the groups. The duration of mechanical ventilation was significantly longer in the inhaled steroid group as compared to the systemic steroid group [typical MD 4 days (95% CI 0.2 to 8); two trials, n = 294] as was the duration of supplemental oxygen [typical MD 11 days (95% CI 2 to 20); two trials, n = 294]. The incidence of hyperglycaemia was significantly lower in the group receiving inhaled steroids [RR 0.52 (95% CI 0.39 to 0.71); RD -0.25 (95% CI -0.37 to -0.14); one trial, n = 278; NNTB 4 (95% CI 3 to 7) to avoid one infant experiencing hyperglycaemia]. The rate of patent ductus arteriosus was increased in the group receiving inhaled steroids [RR 1.64 (95% CI 1.23 to 2.17); RD 0.21 (95% CI 0.10 to 0.33); one trial, n = 278; NNTH 5 (95% CI 3 to 10)]. No information was available on long-term neurodevelopmental outcomes. AUTHORS' CONCLUSIONS This review found no evidence that early inhaled steroids confer important advantages over systemic steroids in the management of ventilator dependent preterm infants. Neither inhaled steroids nor systemic steroids can be recommended as a part of standard practice for ventilated preterm infants. Because they might have fewer adverse effects than systemic steroids, further randomised controlled trials of inhaled steroids are needed that address risk/benefit ratio of different delivery techniques, dosing schedules and long-term effects, with particular attention to neurodevelopmental outcome.

Abstract
BACKGROUND Non-oliguric hyperkalaemia of the newborn is defined as a plasma potassium level > 6.5 mmol/L in the absence of acute renal failure. Hyperkalaemia is a common complication in the first 48 hours of life in very low birth weight (VLBW) (birth weight < 1500 g) and/or very preterm newborns (≤32 weeks gestational age). OBJECTIVES To determine the effectiveness and safety of interventions for non-oliguric hyperkalaemia [for the purpose of this review defined as serum potassium > 6.0 mmol/L (the clinical setting in which interventions would likely be introduced prior to reaching a grossly abnormal level) and urine output > 0.5 ml/kg/hour] in preterm or VLBW infants during their first 72 hours of life. SEARCH METHODS The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2, 2006) was searched to identify relevant randomised and quasi-randomised controlled trials. The following data bases were searched in June 2006; MEDLINE from 1966, EMBASE from 1980, CINAHL from 1982. Search updated in June 2011. SELECTION CRITERIA Randomised or quasi-randomised controlled trials conducted in preterm and/or VLBW neonates with a diagnosis of non-oliguric hyperkalaemia. Interventions included were those aimed at redistributing serum potassium (sodium bicarbonate or insulin and glucose) or increasing the elimination of potassium from the body [diuretics (any type) or ion exchange resins (any type), or exchange transfusion, or peritoneal dialysis, or salbutamol, or albuterol] or counteracting potential arrhythmias from hyperkalaemia (calcium) versus placebo or no intervention; or comparing any two of these interventions. Primary outcome measure was 'All cause mortality during initial hospital stay'. Secondary outcomes included common adverse outcomes seen in preterm infants. DATA COLLECTION AND ANALYSIS We used the standard review methods of the Cochrane Neonatal Review Group. Two authors assessed all studies identified as potentially relevant by the literature search for inclusion in the review. Statistical methods included relative risk (RR), risk difference (RD), number needed to treat to benefit (NNTB) or number needed to treat to harm (NNTH) for dichotomous and weighted mean difference (WMD) for continuous outcomes reported with 95% confidence intervals (CI). We used a fixed effect model for meta-analysis. Heterogeneity was assessed using the I squared (I(2) ) statistic. MAIN RESULTS Three randomised trials, enrolling 74 preterm infants (outcome data available on 71 infants) evaluated interventions for hyperkalaemia. Urine output was ascertained in only one study (Hu 1999). In none of the trials could we ascertain that allocation to the comparison groups was concealed. The sample sizes of the three trials were very small with 12 (Malone 1991), 19 (Singh 2002) and 40 infants enrolled (Hu 1999). The intervention and the outcome assessments could not be blinded to the clinical staff in two trials (Malone 1991; Hu 1999).One study (Malone 1991), glucose and insulin, compared to cation-exchange resin, caused a reduction in all cause mortality that was of borderline statistical significance: RR 0.18 (95% CI 0.03 to 1.15); RD -0.66 (95% CI -1.09 to -0.22); NNTB 2 (95% CI 1 to 5)]. In the study of Hu (Hu 1999), the incidence of intraventricular haemorrhage ≥ grade 2 was significantly reduced [RR 0.30 (95% CI 0.10 to 0.93); RD -0.35 (95% CI -0.62 to -0.08); NNTB 3 (95% CI 2 to 13).Albuterol inhalation versus saline inhalation changed serum K+ from baseline at four hours [WMD -0.69 mmol/L (95% CI -0.87 to -0.51)] and at eight hours [WMD -0.59 mmol/L (95% CI -0.78 to -0.40)] after initiation of treatment. No differences noted in mortality or other clinical outcomes (Singh 2002).No serious side effects were noted with either the combination of insulin and glucose or albuterol inhalation. Other interventions listed in our objectives have not been studied to date. AUTHORS' CONCLUSIONS In view of the limited information from small studies of uncertain quality, no firm recommendations for clinical practice can be made. It appears that the combination of insulin and glucose is preferred over treatment with rectal cation-resin for hyperkalaemia in preterm infants. Both the combination of insulin and glucose and albuterol inhalation deserve further study. The two interventions could possibly be tested against each other. The effectiveness of other potentially effective interventions for non-oliguric hyperkalaemia (diuretics, exchange transfusion, peritoneal dialysis and calcium) have not been tested in randomised controlled trials.

Abstract
BACKGROUND Sepsis is a common problem in preterm and term infants. The incidence of neonatal sepsis has declined, but mortality remains high. Recombinant human activated protein C (rhAPC) possess a broad spectrum of activity modulating coagulation and inflammation. In septic adults it may reduce mortality, but no significant benefit has been reported in children with severe sepsis. OBJECTIVES To determine whether treatment with rhAPC reduces mortality and/or morbidity in neonatal sepsis. SEARCH METHODS For this update searches were carried out in May 2011 of the Cochrane Central Register of Controlled Trials (The Cochrane Library), MEDLINE, EMBASE, CINAHL, and abstracts of annual meetings of the Pediatric Academic Societies. Doctoral dissertations, theses and the Science Citation Index for articles on activated protein C were searched. No language restriction was applied. SELECTION CRITERIA Randomized or quasi-randomized trials, assessing the efficacy of rhAPC compared to placebo or no intervention as an adjunct to antibiotic therapy of suspected or confirmed severe sepsis in term and preterm infants less than 28 days old. Eligible trials should report at least one of the following outcomes: mortality during initial hospital stay, neurodevelopmental assessment at two years of age or later, length of hospital stay, duration of ventilation, chronic lung disease, periventricular leukomalacia, intraventricular haemorrhage, necrotizing enterocolitis, bleeding, and any other adverse events. DATA COLLECTION AND ANALYSIS Review authors were to independently evaluate the articles for inclusion criteria and quality, and abstract information for the outcomes of interest. Differences were to be resolved by consensus. The statistical methods were to include relative risk, risk difference, number needed to treat to benefit or number needed to treat to harm for dichotomous and weighed mean difference for continuous outcomes reported with 95% confidence intervals. A fixed effect model was to be used for meta-analysis. Heterogeneity tests, including the I(2) statistic, were to be performed to assess the appropriateness of pooling the data. MAIN RESULTS No eligible trials were identified. In October 2011 rhAPC (Xigris®) was withdrawn from the market by Eli Lilly due to a higher mortality in a trial among adults. Xigris® (DrotAA)( rhAPC) should no longer be used in any age category and the product should be returned to the distributor. AUTHORS' CONCLUSIONS Despite the scientific rationale for its use, there is insufficient data to use rhAPC for the management of severe sepsis in newborn infants. Due to the results among adults with lack of efficacy, an increase in bleeding and resulting withdrawal of rhAPC from the market, neonates should not be treated with rhAPC and further trials should not be conducted.

Abstract
BACKGROUND Inositol is an essential nutrient required by human cells in culture for growth and survival. Inositol promotes maturation of several components of surfactant and may play a critical role in fetal and early neonatal life. OBJECTIVES To assess the effectiveness/safety of supplementary inositol in preterm infants with respiratory distress syndrome (RDS) in reducing adverse neonatal outcomes. SEARCH METHODS The Cochrane Central Register of Controlled Trials (The Cochrane Library), MEDLINE, EMBASE, CINAHL, Clinicaltrials.gov and Controlled-trials.com were searched in May, 2011. The reference lists of identified randomized controlled trials (RCTs), personal files and Web of Science were searched. SELECTION CRITERIA All RCTs of inositol supplementation to preterm infants with a control group that received a placebo or no intervention were included. Outcomes of interest were neonatal death, infant death, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), and sepsis. DATA COLLECTION AND ANALYSIS Data on neonatal outcomes were abstracted independently by the three review authors and any discrepancy was resolved through consensus. Outcomes were reported as relative risk (RR), risk difference (RD) and number needed to treat to benefit (NNT). MAIN RESULTS Four published and one ongoing randomized controlled trials were identified. Study quality varied and interim analyses had occurred in all trial that provided data for the outcomes. Neonatal death was found to be significantly reduced [three trials, 355 neonates, typical RR 0.53 (95% CI 0.31 to 0.91); RD -0.09 (95% CI -0.17 to -0.03); NNT 11 (95% CI 6 to 33). Infant deaths were reduced [three trials, 355 infants, typical RR 0.55 (95% CI 0.40 to 0.77); RD -0.18 (95% CI -0.27 to -0.08); NNT 6 (95% CI 4 to 13). ROP, stage ≥ 3 was significantly reduced [two trials, 262 infants, typical RR 0.09 (95% CI 0.01 to 0.67); typical RD -0.08 (95% CI -0.13 to -0.03); NNT 13 (95% CI 8 to 33)]. IVH grade > II was significantly decreased [three trials, 355 infants typical RR 0.53 (95% CI 0.31 to 0.90; typical RD -0.09 (95% CI -0.16 to -0.02); NNT 11 (95% CI 6 to 50). Neither sepsis nor NEC differed significantly between groups. One ongoing pharmacokinetics study of inositol in preterm infants was identified. AUTHORS' CONCLUSIONS Inositol supplementation results in statistically significant and clinically important reductions in important short-term adverse neonatal outcomes. A multicenter randomized controlled trial of appropriate size is justified to confirm these findings.

Abstract
OBJECTIVE To compare risk-adjusted changes in outcomes of preterm infants <29 weeks gestation born in 1996 to 1997 with those born in 2006 to 2007. STUDY DESIGN Observational retrospective comparison of data from 15 units that participated in the Canadian Neonatal Network during 1996 to 1997 and 2006 to 2007 was performed. Rates of mortality and common neonatal morbidities were compared after adjustment for confounders. RESULT Data on 1897 infants in 1996 to 1997 and 1866 infants in 2006 to 2007 were analyzed. A higher proportion of patients in the later cohort received antenatal steroids and had lower acuity of illness on admission. Unadjusted analyses revealed reduction in mortality (unadjusted odds ratio (UAOR): 0.83, 95% confidence interval (CI): 0.63, 0.98), severe retinopathy (UAOR: 0.68, 95% CI: 0.50 to 0.92), but increase in bronchopulmonary dysplasia (UAOR: 1.61, 95% CI: 1.39 to 1.86) and patent ductus arteriosus (UAOR: 1.22, 95% CI: 1.07 to 1.39). Adjusted analyses revealed increases in the later cohort for bronchopulmonary dysplasia (adjusted odds ratio (AOR): 1.88, 95% CI: 1.60 to 2.20) and severe neurological injury (AOR: 1.49, 95% CI: 1.22 to 1.80). However, the ascertainment methods for neurological findings and ductus arteriosus differed between the two time periods. CONCLUSION Improvements in prenatal care has resulted in improvement in the quality of care, as reflected by reduced severity of illness and mortality. However, after adjustment of prenatal factors, no improvement in any of the outcomes was observed and on the contrary bronchopulmonary dysplasia increased. There is need for identification and application of postnatal strategies to improve outcomes of extreme preterm infants.

Abstract
CONTEXT Very preterm infants are prone to apnea and have an increased risk of death or disability. Caffeine therapy for apnea of prematurity reduces the rates of cerebral palsy and cognitive delay at 18 months of age. OBJECTIVE To determine whether neonatal caffeine therapy has lasting benefits or newly apparent risks at early school age. DESIGN, SETTING, AND PARTICIPANTS Five-year follow-up from 2005 to 2011 in 31 of 35 academic hospitals in Canada, Australia, Europe, and Israel, where 1932 of 2006 participants (96.3%) had been enrolled in the randomized, placebo-controlled Caffeine for Apnea of Prematurity trial between 1999 and 2004. A total of 1640 children (84.9%) with birth weights of 500 to 1250 g had adequate data for the main outcome at 5 years. MAIN OUTCOME MEASURES Combined outcome of death or survival to 5 years with 1 or more of motor impairment (defined as a Gross Motor Function Classification System level of 3 to 5), cognitive impairment (defined as a Full Scale IQ<70), behavior problems, poor general health, deafness, and blindness. RESULTS The combined outcome of death or disability was not significantly different for the 833 children assigned to caffeine from that for the 807 children assigned to placebo (21.1% vs 24.8%; odds ratio adjusted for center, 0.82; 95% CI, 0.65-1.03; P = .09). The rates of death, motor impairment, behavior problems, poor general health, deafness, and blindness did not differ significantly between the 2 groups. The incidence of cognitive impairment was lower at 5 years than at 18 months and similar in the 2 groups (4.9% vs 5.1%; odds ratio adjusted for center, 0.97; 95% CI, 0.61-1.55; P = .89). CONCLUSION Neonatal caffeine therapy was no longer associated with a significantly improved rate of survival without disability in children with very low birth weights who were assessed at 5 years.

Abstract
The aims of the present study were to assess the practices of breastfeeding supplementation methods, and to explore the opinions and beliefs of health professionals with regard to breastfeeding supplementation methods and the nipple confusion phenomenon. The study was cross-sectional in design, and participants were recruited from five hospitals in Toronto, Ontario. All of the nurses and attending paediatricians in postpartum floors and level II nurseries were invited to participate in the study. A total of 87 nurses and 16 paediatricians completed the survey questionnaire. Bottle feeding was the most common breastfeeding supplementation method used in the nurseries followed by cup feeding. Only 15.0% of the level II nurses agreed that frequent bottle feeds lead to the nipple confusion phenomenon, compared with 44.4% of the postpartum nurses and 56.2% of the paediatricians. Findings demonstrated considerable variation in the practices and beliefs surrounding supplementation methods. A randomized controlled trial comparing the safety, efficiency and subsequent breastfeeding rates of different breastfeeding supplementation methods is warranted.

Abstract
BACKGROUND Heel lance has been the conventional method of blood sampling in neonates for screening tests. Neonates undergoing heel lance experience pain which cannot be completely alleviated. OBJECTIVES To determine whether venepuncture or heel lance is less painful and more effective for blood sampling in term neonates. SEARCH STRATEGY Randomized or quasi-randomised controlled trials comparing pain response to venepuncture versus heel lance were identified by searching the Cochrane Central Regsiter of Controlled Trials (CENTRAL, The Cochrane Library), MEDLINE, EMBASE, CINAHL, and clinical trials registries in May 2011. SELECTION CRITERIA Trials comparing pain response to venepuncture versus heel lance with or with out the use of a sweet tasting solution as a co-intervention in term neonates. DATA COLLECTION AND ANALYSIS Outcomes included pain response to venepuncture versus heel lance with or without the use of a sweet tasting solution using validated pain measures, the need of repeat sampling and cry characteristics. Analyses included typical relative risk (RR), risk difference (RD), number needed to treat (NNT), weighted mean difference (WMD) and standardized mean difference (SMD) with their 95% confidence intervals (CI). Between study heterogeneity was reported including the I squared (I(2)) test. MAIN RESULTS Six studies (n = 478) of variable quality were included. A composite outcome of Infant Pain Scale (NIPS), Neonatal Facial Action Coding System (NFCS) and/or Premature Infant Pain Profile (PIPP) score was reported in 288 infants, who did not receive a sweet tasting solution. Meta-analysis showed a significant reduction in the venepuncture versus the heel lance group (SMD -0.76, 95% CI -1.00 to -0.52; I(2) = 0%). When a sweet tasting solution was provided the SMD remained significant favouring the venepuncture group (SMD - 0.38, 95% CI -0.69 to -0.07). The typical RD for requiring more than one skin puncture for venepuncture versus heel lance (reported in 4 studies; n = 254) was -0.34 (95% CI -0.43 to -0.25; I(2) = 97%). The NNT to avoid one repeat skin puncture was 3 (95% CI 2 to 4). Cry characteristics favoured the venepuncture group but the differences were reduced by the provision of sweet tasting solutions prior to either procedure. AUTHORS' CONCLUSIONS Venepuncture, when performed by a skilled phlebotomist, appears to be the method of choice for blood sampling in term neonates. The use of a sweet tasting solution further reduces the pain.Further well designed randomised controlled trials should be conducted in settings where several individuals perform the procedures.

Abstract
BACKGROUND Large numbers of studies have shown that oral sucrose or glucose, with or without non-nutritive sucking given prior to painful procedures result in a significant reduction in behavioral pain responses during or following painful procedures compared with placebo, no treatment or non-nutritive sucking alone, in newborns and infants up to 12 months of age. It is not known if these pain-reducing effects exist for older infants and children one year to 16 years of age. OBJECTIVES To determine the efficacy of sweet tasting solutions or substances for reducing needle-related procedural pain in children beyond one year of age. SEARCH STRATEGY We searched the following databases: the Cochrane Register of Controlled Trials (CCTR), MEDLINE, EMBASE, PsycINFO, ACP Journal Club, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), Cochrane Methodology Register, Health Technology Assessment, and the NHS Economic Evaluation Database, and on the EBSCOhost interface: CINAHL. We applied no language or document type restrictions. We used the standard methods of The Cochrane Collaboration. The last date of the search was June 30, 2011. SELECTION CRITERIA Randomized controlled trials (RCTs) in which children from one year up to 16 years of age, received a sweet tasting solution or substance for needle-related procedural pain. Control conditions included water, non-sweet tasting substances, pacifier, distraction, no treatment, positioning/containment or breastfeeding. DATA COLLECTION AND ANALYSIS Outcome measures included composite pain scores, physiological or behavioral pain indicators, self-report of pain or parental- or healthcare professional-report of child's pain. We reported mean differences (MD) with 95% confidence intervals (CI) using fixed-effect or random-effects models as appropriate for continuous outcome measures. We planned to report risk ratio (RR) and risk difference (RD) for dichotomous outcomes. We used the Chi(2) test and I(2) statistic to assess between-study heterogeneity. MAIN RESULTS We included four studies (330 participants). Two studies focused on toddlers and pre-school children receiving sucrose for immunization pain compared with water or no treatment and two studies included school-aged children receiving sweet or unsweetened chewing gum before, or, before and during immunization and blood collection. Results for the toddlers/pre-school children were conflicting. Participants in the sucrose group in one study had significantly lower cry duration and behavioral pain scores, compared with the no intervention group, while crying time did not differ between the sucrose and the no intervention group in the other study. For school-aged children, chewing sweet gum either before, or during the procedure, did not significantly reduce pain scores. AUTHORS' CONCLUSIONS Based on these four studies, two of which were subgroups of small numbers of eligible toddlers from larger studies, there is insufficient evidence of the analgesic effects of sweet tasting solutions or substances during acute painful procedures in children over one year of age. Further well-conducted RCTs are warranted in this population.

Abstract
OBJECTIVE A single course of antenatal corticosteroids (ACS) is associated with a reduction in respiratory distress syndrome and neonatal death. Multiple Courses of Antenatal Corticosteroids Study (MACS), a study involving 1858 women, was a multicentre randomized placebo-controlled trial of multiple courses of ACS, given every 14 days until 33+6 weeks or birth, whichever came first. The primary outcome of the study, a composite of neonatal mortality and morbidity, was similar for the multiple ACS and placebo groups (12.9% vs. 12.5%), but infants exposed to multiple courses of ACS weighed less, were shorter, and had smaller head circumferences. Thus for women who remain at increased risk of preterm birth, multiple courses of ACS (every 14 days) are not recommended. Chronic use of corticosteroids is associated with numerous side effects including weight gain and depression. The aim of this postpartum assessment was to ascertain if multiple courses of ACS were associated with maternal side effects. METHODS Three months postpartum, women who participated in MACS were asked to complete a structured questionnaire that asked about maternal side effects of corticosteroid use during MACS and included the Edinburgh Postnatal Depression Scale. Women were also asked to evaluate their study participation. RESULTS Of the 1858 women randomized, 1712 (92.1%) completed the postpartum questionnaire. There were no significant differences in the risk of maternal side effects between the two groups. Large numbers of women met the criteria for postpartum depression (14.1% in the ACS vs. 16.0% in the placebo group). Most women (94.1%) responded that they would participate in the trial again. CONCLUSION In pregnancy, corticosteroids are given to women for fetal lung maturation and for the treatment of various maternal diseases. In this international multicentre randomized controlled trial, multiple courses of ACS (every 14 days) were not associated with maternal side effects, and the majority of women responded that they would participate in such a study again.

Abstract
BACKGROUND Persistent pulmonary hypertension in neonates (PPHN) is associated with high mortality. Currently, the therapeutic mainstay for PPHN is assisted ventilation and administration of inhaled nitric oxide (iNO). However, nitric oxide is costly and may not be appropriate in resource-poor settings. Approximately 30% of patients fail to respond to iNO. High concentrations of phosphodiesterases in the pulmonary vasculature has led to the use of phosphodiesterase inhibitors such as sildenafil or milrinone. OBJECTIVES To assess the efficacy and safety of sildenafil in the treatment of persistent pulmonary hypertension in neonates. SEARCH STRATEGY The Cochrane Central Register of Controlled Trials (The Cochrane Library), MEDLINE, EMBASE, CINAHL databases were searched from their inception until December 2010; Clinicaltrials.gov web site, the reference lists of identified trials, and abstracts of meetings were searched without any language restriction. SELECTION CRITERIA Randomised or quasi-randomised controlled trials of sildenafil compared with placebo or other pulmonary vasodilators, irrespective of dose, route and duration of administration in neonates with PPHN, were included if the trial reported any of the pre-specified outcomes. DATA COLLECTION AND ANALYSIS The methodological quality of the trials was assessed regarding how bias was minimized at study entry, during study intervention and at outcomes measurement. Data on relevant outcomes were extracted and the effect size was estimated and reported as relative risk (RR), risk difference (RD) and weighted mean difference (MD) as appropriate. The I-squared (I(2)) test of heterogeneity was applied. MAIN RESULTS Three eligible trials that enrolled 77 infants were identified. The methodological quality of the studies indicated low-moderate risk of bias. All studies were performed in resource-limited settings where iNO and high frequency ventilation were not available at the time of study. There was significant reduction in mortality in the sildenafil group (typical RR 0.20, 95% CI 0.07 to 0.57; typical RD -0.38, 95% CI -0.60 to -0.16; Number needed to treat to benefit 3, 95% CI 2 to 6). Physiological parameters of oxygenation (oxygenation index, PaO(2)) suggested a steady improvement after the first dose of sildenafil. No clinically important side effects were identified. AUTHORS' CONCLUSIONS Sildenafil in the treatment of PPHN has significant potential especially in resource limited settings. However, a large scale randomised trial comparing sildenafil with the currently used vasodilator, inhaled nitric oxide, is needed to assess efficacy and safety.
