Neurorehabilitation after neonatal intensive care: evidence and challenges

Neonatologists and paediatric providers of developmental care have documented poor neurodevelopmental outcomes of infants who have received neonatal intensive care due to prematurity, perinatal neurological insults such as asphyxia or congenital anomalies such as congenital heart disease. In parallel, developmental specialists have researched treatment options in these high-risk children. The goal of this review is connect the main categories of poor outcomes (sensory and motor function, cognition, communication, behaviour) studied by neonatal intensive care follow-up specialists to the research focused on improving these outcomes. We summarise challenges in designing diagnostic and interventional approaches in infants <2 years of age and review the evidence for existing therapies and future treatments aimed at improving functionality.

Impact of neonatal intensive care bed configuration on rates of late-onset bacterial sepsis and methicillin-resistant Staphylococcus aureus colonization

BACKGROUND

Infections cause morbidity and mortality in neonatal intensive care units (NICUs). The association between nursery design and nosocomial infections is unclear.

OBJECTIVE

To determine whether rates of colonization by methicillin-resistant Staphylococcus aureus (MRSA), late-onset sepsis, and mortality are reduced in single-patient rooms. DESIGN Retrospective cohort study.

SETTING

NICU in a tertiary referral center.

METHODS

Our NICU is organized into single-patient and open-unit rooms. Clinical data sets including bed location and microbiology results were examined over 29 months. Differences in outcomes between bed configurations were determined by χ2 and Cox regression.

PATIENTS

All NICU patients.

RESULTS

Among 1,823 patients representing 55,166 patient-days, single-patient and open-unit models had similar incidences of MRSA colonization and MRSA colonization-free survival times. Average daily census was associated with MRSA colonization rates only in single-patient rooms (hazard ratio, 1.31; P=.039), whereas hand hygiene compliance on room entry and exit was associated with lower colonization rates independent of bed configuration (hazard ratios, 0.834 and 0.719 per 1% higher compliance, respectively). Late-onset sepsis rates were similar in single-patient and open-unit models as were sepsis-free survival and the combined outcome of sepsis or death. After controlling for demographic, clinical, and unit-based variables, multivariate Cox regression demonstrated that bed configuration had no effect on MRSA colonization, late-onset sepsis, or mortality.

CONCLUSIONS

MRSA colonization rate was impacted by hand hygiene compliance, regardless of room configuration, whereas average daily census affected only infants in single-patient rooms. Single-patient rooms did not reduce the rates of MRSA colonization, late-onset sepsis, or death.

Providing immediate neonatal care and resuscitation at birth beside the mother: clinicians' views, a qualitative study

OBJECTIVES

The aims of this study were to assess clinicians' views and experiences of providing immediate neonatal care at birth beside the mother, and of using a mobile trolley designed to facilitate this bedside care.

DESIGN

Qualitative interview study with semistructured interviews.

RESULTS

The results were analysed using thematic analysis.

SETTING

A large UK maternity unit.

PARTICIPANTS

Clinicians (n=20) from a range of disciplines who were present when the trolley was used to provide neonatal care at birth at the bedside. Five clinicians provided/observed advanced resuscitation by the bedside.

RESULTS

Five themes were identified: (1) Parents' involvement, which included 'Contact and involvement', 'Positive emotions for parents' and 'Staff communication'; (2) Reservations about neonatal care at birth beside the mother, which included 'Impact on clinicians' and 'Impact on parents'; (3) Practical challenges in providing neonatal care at the bedside, which included 'Cord length' and 'Caesarean section'; (4) Comparison of the trolley with usual resuscitation equipment and (5) Training and integration of bedside care into clinical routine, which included 'Teething problems' and 'Training'.

CONCLUSIONS

Overall, most clinicians were positive about providing immediate neonatal care at the maternal bedside, particularly in terms of the clinicians' perceptions of the parents' experience. Clinicians also perceived that their close proximity to parents improved communication. However, there was some concern about performing more intensive interventions in front of parents. Providing immediate neonatal care and resuscitation at the bedside requires staff training and support.

Providing immediate neonatal care and resuscitation at birth beside the mother: parents' views, a qualitative study

OBJECTIVES

The aims of this study were to assess parents' views of immediate neonatal care and resuscitation at birth being provided beside the mother, and their experiences of a mobile trolley designed to facilitate this bedside care.

DESIGN

Qualitative study with semistructured interviews. Results were analysed using thematic analysis.

SETTING

Large UK maternity hospital.

PARTICIPANTS

Mothers whose baby received initial neonatal care in the first few minutes of life at the bedside, and their birth partners, were eligible. 30 participants were interviewed (19 mothers, 10 partners and 1 grandmother). 5 babies required advanced neonatal resuscitation.

RESULTS

5 themes were identified: (1) Reassurance, which included 'Baby is OK', 'Having baby close', 'Confidence in care', 'Knowing what's going on' and 'Dad as informant'; (2) Involvement of the family, which included 'Opportunity for contact', 'Family involvement' and 'Normality'; (3) Staff communication, which included 'Communication' and 'Experience'; (4) Reservations, which included 'Reservations about witnessing resuscitation', 'Negative emotions' and 'Worries about the impact on staff' and (5) Experiences of the trolley, which included 'Practical issues' and 'Comparisons with standard resuscitation equipment'.

CONCLUSIONS

Families were positive about neonatal care being provided at the bedside, and felt it gave reassurance about their baby's health and care. They also reported feeling involved as a family. Some parents reported experiencing negative emotions as a result of witnessing resuscitation of their baby. Parents were positive about the trolley.

The baby cooling project of Japan to implement evidence-based neonatal cooling

Therapeutic hypothermia was first recommended as a standard of care by international guidelines in 2010. However, at that time, the number of centers capable of providing standard cooling was limited even in Japan. The aim of this project was to implement a nationwide network of evidence-based cooling within 3 years. A taskforce was formed in June 2010 to undergo the primary nationwide practice survey, design of action plans, and the appraisal of interventions by involving all registered level-II/III neonatal intensive care units in Japan. Based on findings from the primary survey, aggressive action plans were introduced that focused on the formulation of clinical recommendations, facilitation of educational events, and opening of an online case registry. Findings from the follow-up survey (January 2013) were compared with the results from the primary survey (June 2010). Four workshops and three consensus meetings were held to formulate clinical recommendations, which were followed by the publication of practical textbooks, large-scale education seminars, and implementation of a case registry. A follow-up survey covering 253 units (response rate: 89.1%) showed that cooling centers increased from 89 to 135. Twelve prefectures had no cooling centers in 2010, whereas all 47 prefectures had at least one in 2013. In cooling centers, adherence to the standard cooling protocols and the use of servo-controlled cooling devices improved from 20.7% to 94.7% and from 79.8% to 98.5%, respectively. A rapid improvement in the national provision of evidence-based cooling was achieved. International consensus guidelines coupled with domestic interventions might be effective in changing empirical approaches to evidence-based practice.

Needs assessment to improve neonatal intensive care in Mexico

BACKGROUND

At the time of the research, Dr Weiss was a clinical fellow in neonatal-perinatal medicine at Baylor College of Medicine, Texas Children's Hospital. Dr Profit was on faculty at Baylor College of Medicine, Texas Children's Hospital, Department of Pediatrics, Section of Neonatology. He held a secondary appointment in the Department of Medicine, Section of Health Services Research and conducted his research at the VA Health Services Research and Development Center of Excellence where he collaborated with Dr Kowalkowski.: Improving the quality of neonatal intensive care is an important health policy priority in Mexico. A formal assessment of barriers and priorities for quality improvement has not been undertaken.

AIM

To provide guidance to providers and policy makers with regard to addressing opportunities for better care delivery in Mexican neonatal intensive care units.

OBJECTIVE

To conduct a needs assessment regarding improvement of quality of neonatal intensive care delivery in Mexico.

METHODS

Spanish-language survey administered to a volunteer sample of Mexican neonatal care providers attending a large paediatric conference in Mexico in June 2011. Survey domains included institutional context of quality improvement, barriers, priorities, safety culture, and respondents' characteristics. Results were analysed using descriptive analyses of frequencies, proportions and percentage positive response (PPR) rates.

RESULTS

Of 91 respondents, the majority identified neonatology as their primary specialty (n = 48, 65%) and were physicians (n = 55, 73%). Generally, providers expressed a desire to improve quality of care (PPR 69%) but reported notable deterrents. Respondents (n, %) identified family inability to pay (38, 48%), overcrowded work areas (38, 44%), insufficient financial reimbursement (25, 36%), lack of availability of nurses (26, 30%), ancillary staff (25, 29%), and subspecialists (22, 25%) as the principal barriers. Respiratory care (27, 39%)--reduction of mechanical ventilation and initiation of nasal continuous positive airway pressure--and reduction in frequency of late-onset infections (19, 28%) were selected as top clinical priorities. There were substantial opportunities for improving safety (PPR 48%) and teamwork climate (PPR 58%).

CONCLUSION

These findings may guide efforts to improving quality of care delivery in Mexican neonatal intensive care units.

Integration of drug dosing data with physiological data streams using a cloud computing paradigm

Many drugs are used during the provision of intensive care for the preterm newborn infant. Recommendations for drug dosing in newborns depend upon data from population based pharmacokinetic research. There is a need to be able to modify drug dosing in response to the preterm infant's response to the standard dosing recommendations. The real-time integration of physiological data with drug dosing data would facilitate individualised drug dosing for these immature infants. This paper proposes the use of a novel computational framework that employs real-time, temporal data analysis for this task. Deployment of the framework within the cloud computing paradigm will enable widespread distribution of individualized drug dosing for newborn infants.

A Continuous Quality Improvement Project to Implement Infant-Driven Feeding as a Standard of Practice in the Newborn/Infant Intensive Care Unit

OBJECTIVE

To increase the number of neonates who were fed according to cues prior to discharge and potentially decrease length of stay.

DESIGN

Continuous quality improvement.

SETTING

Eighty-five bed level IV neonatal intensive care unit.

PATIENTS

Surgical and nonsurgical neonates of all gestational ages. Neonates younger than 32 weeks gestation, who required intubation, continuous positive airway pressure (CPAP), high flow nasal cannula (HFNC), or did not have suck or gag reflexes were excluded as potential candidates for infant-driven feeding.

INTERVENTION/MEASUREMENTS

The project was conducted over a 13-month period using the following methods: (a) baseline data collection, (b) designation of Infant Driven Feeding (IDF) Champions, (c) creation of a multidisciplinary team, (d) creation of electronic health record documentation, (e) initial staff education, (f) monthly team meetings, (g) reeducation throughout the duration of the project, and (h) patient-family education.

RESULTS

Baseline data were collected on 20 neonates with a mean gestational age of 36 0/7(th) weeks and a mean total length of stay (LOS) of 43 days. Postimplementation data were collected on 150 neonates with a mean gestational age of 36 1/7(th) weeks and a mean total LOS of 36.4 days. A potential decrease in the mean total LOS of stay by 6.63 days was achieved during this continuous quality improvement (CQI) project.

CONCLUSIONS

Neonates who are fed according to cues can become successful oral feeders and can be safely discharged home regardless of gestational age or diagnosis.

Utility of Targeted Neonatal Echocardiography in the Management of Neonatal Illness

OBJECTIVES

To describe the impact of targeted neonatal echocardiography on management of neonatal illness in a tertiary perinatal center neonatal intensive care unit (NICU).

METHODS

We conducted a retrospective analysis of consecutive targeted neonatal echocardiographic studies that were performed over an 18-month period in a regional perinatal center NICU in Canada. All studies were performed with a cardiovascular ultrasound machine and transducer and read on a workstation with storage and analysis software. Reporting was done on a standardized document, and any management change resulting from targeted neonatal echocardiography was documented.

RESULTS

A total of 303 consecutive targeted neonatal echocardiographic studies were performed on 129 neonates. The mean gestational age ± SD was 27.8 ± 4.3 weeks (range, 23-41 weeks), and the mean birth weight ± SD was 1196 ± 197 g (range, 490- 4500 g). The median number of studies per neonate was 2 (range, 1-8), with most repeated studies for a patent ductus arteriosus (PDA). The most common indication for echocardiography was assessment of a PDA (52.1%), followed by early global hemodynamic assessment of very low birth weight (16.2%) and pulmonary hypertension (12.2%). Of the 303 studies, 126 (41.5%) resulted in management changes. The contribution to management was significantly related to the timing of echocardiography. Around half of the echocardiographic examinations during first the week of life resulted in management changes, compared to 22% of studies after 1 week of age (P = .002). Patent ductus arteriosus management accounted for almost half of the interventions.

CONCLUSIONS

Targeted neonatal echocardiography is a valuable tool in the NICU and can contribute substantially to hemodynamic management in the first week of life, PDA management in the first 2 weeks of life, and cases of hypotension or shock at any time during the hospital stay.

ASSESSMENT OF BODY COMPOSITION USING BIOELECTRICAL IMPEDANCE ANALYSIS IN PRETERM NEONATES RECEIVING INTENSIVE CARE

AIM

Evaluation of bioelectrical impedance values and body composition during early infancy in groups of preterm newborns and full-term newborns.

MATERIAL AND METHODS

A total of 38 newborns was enrolled in the study: 26 very low birth weight preterm newborns with the mean birth weight of 1236 g (SD: 161) as the study group and 12 term newborns with birth weight of 2500-4000 g as the control group. Anthropometric measurements and body composition using bioimpedance analysis at the age of 1 week and at the age of 3 months were assessed.

RESULTS

At the age of 1 week we noted higher resistance with the impedance variables R5, R50 R100 in the group of preterm newborns compared to the full-term newborns' group (923(144) vs. 647(78) p < 0.01; 870 (140) vs. 615 (73) p < 0.01; 844 (141) vs. 599 (72) p < 0.01). Moreover, the bioimpedance index and fat mass (%) were significantly lower in the group of preterm infants at the age of 3 months (3.81 (0.9) vs. 5.72 (1.1) p < 0.01; 16.1% (1.7) vs. 18.9% (2.7) p = 0.006). We observed a decreased amount of the percentage of total body water (TBW%) in both of the analyzed infant groups throughout the observational period. At the age of 3 months the amount of TBW % was similar in both groups (71.5% (7.03) vs. 70.8% (8.8) p = 0.8).

CONCLUSIONS

Bioimpedance analysis is a simple, non-invasive, repeatable method to estimate total body water, fat-free mass, and fat mass, both in term and preterm newborns. The study confirms differences in body composition between preterm newborns and full-term newborns. Moreover, we have shown that the differences are present until the end of the 3rd month of life, with the exception of the amount of water percentage (TBW %), which are similar in both groups.

Determination of methods used by the neonatal care unit nurses for management of procedural pain in Turkey

OBJECTIVE

To determine the pharmacological and non-pharmacological methods used by neonatal intensive care unit nurses to reduce procedural pain.

METHODS

The cross-sectional study was conducted from September 2011 to June 2012 and comprised nurses employed in the paediatric departments, consisting of neonatal intensive care units and newborn units, of 15 hospitals in various cities of Turkey: 8 in Istanbul, 3 in Izmir and two each in Antalya and Edirne. Data was collected using a questionnaire and analysed using SPSS 15.

RESULTS

The mean age of the 486 nurses was 28.19±5.14 years; 316(65%) had bachelor's degrees; 278(57.2%) had nursing experience greater than 6 years; and 322(72.5%) had newborn nursing experience greater than 6 years. Overall, 364(74.9%) nurses used non-pharmacological methods, and 145(29.8%) used pharmacological methods for pain relief. The most commonly used non-pharmacological methods were skin touch 364(75%) and giving a pacifier 269(55.3%). The most commonly used pharmacological methods were paracetamol and ibuprofen by 145(29.8%) nurses. A statistically significant difference was found between the level of education and use of pharmacological and non-pharmacological methods for pain relief (p< 0.05).

CONCLUSIONS

Among the nurses in both groups, very little pain management was used for invasive procedures. Educational programmes for pain management in newborns should be arranged to develop an institutional culture. Guidelines for these patients' pain management should also be established.

[Nutrition and Hydration in Newborns: Limiting Treatment Decisions]

Artificial hydration and nutrition are key elements in the treatment in Neonatal Units, especially in premature babies. It has led to improved survival and better clinical outcomes. Artificial nutrition is considered a medical treatment and, in such a way, a balance between burdens and benefits should be taken into consideration. Nevertheless decisions on withholding or withdrawing artificial nutrition and hydration have special and emotional considerations. In premature babies it is also necessary to consider than below the 34th week of gestational age, effective suckling is not present, and so, oral nutrition is not a possibility. Decisions regarding the end-of-life care of neonates should be made taking into account clinical facts but also values and beliefs of all concerned, and always ″in the best interest″ of infants. In order to consider all this aspects, we could respect withdrawing or withholding artificial nutrition and hydration in those babies with an ominous prognosis in a short term basis. It has not the same consideration if there is a clear life risk but a prognosis based on severe future burden, mainly because of neurologic damage. In those cases withholding or withdrawing fluids and feedings would be the direct cause of death.

Effect of cobedding twins on coregulation, infant state, and twin safety

OBJECTIVE

To evaluate the efficacy of cobedding on twin coregulation and twin safety.

DESIGN

Randomized controlled trial (RCT).

SETTING

Two university affiliated Level III neonatal intensive care units (NICUs).

PARTICIPANTS

One hundred and seventeen sets (N = 234) of stable preterm twins (<37 weeks gestational age at birth) admitted to the NICU.

METHODS

Sets of twins were randomly assigned to be cared for in a single cot (cobedded) or in separate cots (standard care). State response was obtained from videotaped and physiologic data measured and recorded for three, 3-hour sessions over a one-week study period. Tapes were coded for infant state by an assessor blind to the purpose of the study.

RESULTS

Twins who were cobedded spent more time in the same state (p < .01), less time in opposite states (p < .01), were more often in quiet sleep (p < .01) and cried less (p < .01) than twins who were cared for in separate cots. There was no difference in physiological parameters between groups (p = .85). There was no difference in patient safety between groups (incidence of sepsis, p = .95), incidence of caregiver error (p = .31), and incidence of apnea (p = .70).

CONCLUSIONS

Cobedding promotes self-regulation and sleep and decreases crying without apparent increased risk.

The Neonatal Pain, Agitation and Sedation Scale and the bedside nurse's assessment of neonates

OBJECTIVE

To determine the reliability of an objective measure of pain, agitation and sedation using the Neonatal Pain, Agitation and Sedation Scale (N-PASS) compared with nursing bedside assessment.

STUDY DESIGN

Neonates admitted in neonatal intensive care unit over a 6-month period were eligible. Pain and sedation were assessed with N-PASS, and a subjective questionnaire was administered to the bedside nurse.

RESULT

A total of 218 neonates were eligible (median: gestational age 34.6 weeks, age at assessment 7 days). N-PASS pain score correlated significantly with both nurses' pain score (Spearman coefficient (r)=0.37; P<0.001) and agitation score (r=0.56; P<0.001). N-PASS sedation score correlated with nurses' sedation score (r=-0.39; P<0.001). Adjusting for gestational age, day of life, intrauterine drug exposure and use of high frequency ventilation only slightly attenuated the correlations (r=0.36, 0.55 and -0.31, respectively).

CONCLUSION

The N-PASS captures nursing assessment of pain, agitation and sedation in this broad population and provides a quantitative assessment of subjective descriptions that often drives patient therapy.

[Survival and complication rate of central venous catheters in newborns]

BACKGROUND

In the current medical practice, central venous catheters (CVC) are very useful; however, their use involves certain risks, which increase morbidity and mortality, especially in newborns. The aim of this study was to describe both the frequency of complications and survival of CVC placed in newborns hospitalized in a third level neonatal intensive care unit (NICU).

METHODS

A descriptive, observational and prospective study was carried-out in the NICU from the Hospital de Pediatría, Centro Médico Nacional Siglo XXI. Demographic, perinatal and CVC variables were recorded.

RESULTS

We included 152 CVCs, which were inserted in 123 newborns. For the CVC insertion, the puncture technique [percutaneous and subclavian] was used in 56.6 % (n = 86). There was at least one complication in 48.7 %.(n = 74). The most frequent complications were colonization 32.4 % (n = 24) and CVC-related bacteremia in 27 % (n = 20). Survival probability for CVC was 93.4 % at 10 days and 91.4 % at 17 days. Kaplan-Meier survival analysis demonstrated significantly lower survival probability for non-central catheters.

CONCLUSIONS

Most of CVC complications occurred within the first two weeks after these CVC were installed. Infectious complications were the most frequent.

SUPPORT and the Ethics of Study Implementation: Lessons for Comparative Effectiveness Research from the Trial of Oxygen Therapy for Premature Babies

The design of SUPPORT has been widely misunderstood. This confusion has driven much of the debate about the trial - and threatens the whole enterpise of comparative effectiveness research.

Were There "Additional Foreseeable Risks" in the SUPPORT Study? Lessons Not Learned from the ARDSnet Clinical Trials

Even though the interventions were adapted from standard clinical practice, the way they were provided meant that the care given infants in the study was distinctly different from standard care, with different risk profiles. Parents should have been informed about those differences.

Surfactant from neonatal to pediatric ICU: bench and bedside evidence

Surfactant is a cornerstone of neonatal critical care for the treatment of respiratory distress syndrome of preterm babies. However, other indications have been studied for various clinical conditions both in term neonates and in children beyond neonatal age. A high degree of evidence is not yet available in some cases and this is due to the complex and not yet totally understood physiopathology of the different types of pediatric and neonatal lung injury. We here summarise the state of the art of the bench and bedside knowledge about surfactant use for the respiratory conditions usually cared for in neonatal and pediatric intensive care units. Future research direction will also be presented. On the whole, surfactant is able to improve oxygenation in infection related respiratory failure, pulmonary hemorrhage and meconium aspiration syndrome. Bronchoalveolar lavage with surfactant solution is currently the only means to reduce mortality or need for extracorporeal life support in neonates with meconium aspiration. While surfactant bolus or lavage only improves the oxygenation and ventilatory requirements in other types of postneonatal acute respiratory distress syndrome (ARDS), there seems to be a reduction in the mortality of small infants with RSV-related ARDS.

[Consensus on the diagnostic and therapeutic approach to pain and stress in the newborn]

Pain and stress experienced by the newborn have not been addressed adequately. Infants in neonatal intensive care units often undergo painful and stressful invasive procedures, and inappropriate treatment increases morbidity and mortality. At the 5th Clinical Consensus of the Ibero-American Society of Neonatology, 32 neonatologists from the region were invited to establish recommendations for the diagnosis and treatment of neonatal pain and stress. Key themes were explored based on the best scientific evidence available in indexed databases. All attendees participated actively in a meeting in Santiago, Chile, with the objective of reaching a consensus on recommendations and conclusions. Pain and neonatal stress affect neurological development and long-term behavior and require timely diagnosis and appropriate management and treatment, including the use of drugs with an appropriate balance between effectiveness and toxicity. The Consensus emphasized the importance of assessing pain in the newborn from a multidimensional viewpoint, and provided recommendations on the indications and limitations for an individualized pharmacological therapy. The use of analgesics has precise indications but also important limitations; there is a lack of randomized studies in newborns, and adverse effects need to be considered. Nonpharmacological measures to mitigate pain were proposed. Stress management should begin in the delivery room, including maternal contact, stimulus reduction and the implementation of intervention reduction protocols. Recommendations for improving clinical practices related to neonatal pain and stress are presented.

Viral respiratory tract infections in the neonatal intensive care unit: the VIRIoN-I study

OBJECTIVE

To determine the frequency of respiratory viral infections among infants who were evaluated for late-onset sepsis in the neonatal intensive care units (NICUs) of Parkland Memorial Hospital, Dallas, Texas; and Women & Infants Hospital, Providence, Rhode Island.

STUDY DESIGN

Prospective cohort study conducted from January 15, 2012 to January 31, 2013. Infants in the NICU were enrolled if they were inborn, had never been discharged home, and were evaluated for sepsis (at >72 hours of age) and antibiotic therapy was initiated. Infants had a nasopharyngeal specimen collected for detection of respiratory viruses by multiplex polymerase chain reaction within 72 hours of the initiation of antibiotic therapy. Their medical records were reviewed for demographic, clinical, radiographic, and laboratory data until NICU discharge.

RESULTS

During the 13-month study, 8 of 100 infants, or 8 (6%) of the 135 sepsis evaluations, had a respiratory virus detected by polymerase chain reaction (2, enterovirus/rhinovirus; 2, rhinovirus; 2, coronaviruses; and 2, parainfluenza-3 virus). By bivariate analysis, the infants with viral detection were older (41 vs 11 days; P = .007), exposed to individuals with respiratory tract viral symptoms (37% vs 2%; P = .003), tested for respiratory viruses by provider (75% vs 11%; P < .001), and had lower total neutrophil counts (P = .02). In multivariate regression analysis, the best predictor of viral infection was the caregivers' clinical suspicion of viral infection (P = .006).

CONCLUSIONS

A total of 8% of infants, or 6% of all NICU sepsis evaluations, had a respiratory virus detected when evaluated for bacterial sepsis. These findings argue for more respiratory viral testing of infants with suspected sepsis using optimal molecular assays to establish accurate diagnoses, prevent transmission, and inform antibiotic stewardship efforts.

Family-centered rounds in the neonatal intensive care unit

Promotion of family-centered care is common in neonatal intensive care units (NICUs) across the nation. Yet, true collaboration and shared decision-making with families in the care of their baby is not the standard of care. Family-centered rounds can provide the opportunity for this level of collaboration, but care must be taken to overcome barriers to family-centered rounds.

Change in practice after the Surfactant, Positive Pressure and Oxygenation Randomised Trial

OBJECTIVE

To test the hypothesis that the proportion of endotracheal intubation (ETI) in the delivery room (DR) decreased in Neonatal Research Network (NRN) centres after the National Institute of Child Health and Human Development NRN Surfactant, Positive Pressure, and Oxygenation Randomised Trial (SUPPORT).

DESIGN

Retrospective cohort study using the prospective NRN generic database.

SETTING

Eleven centres that participated in the SUPPORT trial and remained part of the NRN. Preterm neonates 24(0/7)-27(6/7) weeks' gestational age enrolled in the SUPPORT trial were randomised to: (1) DR continuous positive airway pressure or DR ETI with early surfactant administration; and (2) oxygen saturation targets of 85-89% or 91-95%. The prior NRN feasibility trial had assessed the feasibility of randomisation to continuous positive airway pressure versus ETI.

PATIENTS

Infants 24(0/7)-27(6/7) weeks' gestational age, excluding infants with syndromes or major malformations and those on comfort care only.

MAIN OUTCOME MEASURE

Proportion of DR ETI.

RESULTS

The proportion of DR ETI decreased significantly in the group of infants from centres that had not participated in the feasibility trial (91% before vs 75% after SUPPORT, adjusted relative risk 0.86, 95% CI 0.83-0.89, p<0.0001) but not in the group of infants from the other centres, where the proportion of ETI was already lower prior to initiation of the SUPPORT trial (61% before vs 58% after SUPPORT, adjusted relative risk 0.96, 95% CI 0.89 to 1.05, p=0.40).

CONCLUSION

This study shows that DR ETI changed after SUPPORT only in NRN centres that had not participated in a similar trial.

TRIAL REGISTRATION NUMBER

NCT00063063 (GDB) and NCT00233324 (SUPPORT).

Methods for securing endotracheal tubes in newborn infants

BACKGROUND

Securing the endotracheal tube is a common procedure in the neonatal intensive care unit. Adequate fixation of the tube is essential to ensure effective ventilation of the infant whilst minimising potential complications secondary to the intervention. Methods used to secure the endotracheal tube often vary between units and sometimes even between healthcare providers in the same nursery.

OBJECTIVES

To compare the different methods of securing the endotracheal tube in the ventilated neonate and their effects on the risk of accidental extubation and other potential complications that can result from an unstable endotracheal tube.

SEARCH METHODS

A literature search of MEDLINE (from 1966 to June 2013), CINAHL (from 1982 to June 2013) and CENTRAL in The Cochrane Library was conducted to identify relevant trials to be analysed.

SELECTION CRITERIA

All randomised and quasi-randomised controlled trials of infants who were intubated for mechanical ventilation in a neonatal intensive care nursery where methods of stabilising the endotracheal tube were being compared.

DATA COLLECTION AND ANALYSIS

Data were collected from individual studies to determine the methods being compared, the methodology of the trial, and whether there were areas of bias that could significantly affect the results of the studies. In particular, studies were assessed for blinding of randomisation and allocation, blinding of the intervention, completeness of follow up, blinding of outcome assessments and selective reporting.

MAIN RESULTS

Five randomised controlled trials were identified and included for review. Accidental extubation was the most common outcome measured (five studies). None of the studies reported on the need for re-intubation or the rate of tube malposition, however one study did report on endotracheal tube slippage. A variety of other adverse effects were reported including mortality, incidence of perioral skin trauma and tube re-taping. All five studies were of poor methodological quality, small size, contained significant risks of bias and compared methods of securing the endotracheal tube that were too dissimilar for the data to be collated or included in a meta-analysis. We have not reported these further.

AUTHORS' CONCLUSIONS

This review highlighted the need for further well designed and completed studies to be conducted for this common neonatal procedure. Evidence is lacking to determine the most effective and safe method to stabilise the endotracheal tube in the ventilated neonate.

[SODIUM SUCCINATE AS METHOD OF INTENSIVE CARE OPTIMIZATION OF NEWBORNS' MULTIORGAN FAILURE SYNDROM]

With the aim of ascertainment of pathogenesis of newborns' multiorgan failure syndrom it was made a research of lactat, pyruvate, urea containing and succinatedehydrogenase activity of newborns venous blood with sequences to perinatal infection and perinatal asphyxia. Was set the reliable increase of concentration of lactat, pyruvate and their ratio, that demonstrates the presence of cellular energy deficit. There was direct correlation communication between concentrations of pyruvate and urea. In the application of sodium succinate to reduce the content of lactic and pyruvic acids, their ratio, increase the activity of succinatedehydrogenase, which is evidence of improved mitochondrial energy production, as well as reduces the frequency of gastrointestinal insufficiency implementation.
