Abstract
Premature births account for over 10% of live births worldwide. Bronchopulmonary dysplasia (BPD) represents a severe sequela in neonates born very prematurely and remains the most common chronic neonatal lung disease, often leading to serious adverse consequences in adulthood. Nutrition plays a crucial role in lung development and repair. Ongoing research has primarily focused on the pathogenesis and prevention of BPD in preterm birth. However, infants with established BPD need specialist medical care that persists throughout their hospitalization and continues after discharge. This manuscript aims to highlight the impact of growth and nutrition on BPD and highlight research gaps to provide direction for future studies. Protective practices include ensuring adequate early energy delivery through parenteral nutrition and enteral feedings while carefully monitoring total fluid intake and the use of breast milk over formula. These nutritional strategies remain the same for infants with established BPD with the addition of limiting the use of diuretics and steroids; but if employed, monitoring carefully without compromising total energy delivery. Functional nutrient supplements with a potential protective role against BPD are revisited, despite the limited evidence of their efficacy, including vitamins, trace elements, zinc, lipids, and sphingolipids. Planning post-intensive care and outpatient longitudinal nutrition support is critical in caring for an infant with established BPD.

Effect of reduced versus usual lipid emulsion dosing on bilirubin neurotoxicity and neurodevelopmental impairment in extremely preterm infants: study protocol for a randomized controlled trial. BMC Pediatr 2023; 23:347. [PMID: 37430233 PMCID: PMC10332033 DOI: 10.1186/s12887-023-04149-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 06/22/2023] [Indexed: 07/12/2023] Open
Abstract
BACKGROUND Bilirubin neurotoxicity (BN) occurs in premature infants at lower total serum bilirubin levels than term infants and causes neurodevelopmental impairment. Usual dose lipid infusions in preterm infants may increase free fatty acids sufficiently to cause bilirubin displacement from albumin, increasing passage of unbound bilirubin (UB) into the brain leading to BN and neurodevelopmental impairment not reliably identifiable in infancy. These risks may be influenced by whether cycled or continuous phototherapy is used to control bilirubin levels. OBJECTIVE To assess differences in wave V latency measured by brainstem auditory evoked responses (BAER) at 34-36 weeks gestational age in infants born ≤ 750 g or < 27 weeks' gestational age randomized to receive usual or reduced dose lipid emulsion (half of the usual dose) irrespective of whether cycled or continuous phototherapy is administered. METHODS Pilot factorial randomized controlled trial (RCT) of lipid dosing (usual and reduced) with treatment groups balanced between cycled or continuous phototherapy assignment. Eligible infants are born at ≤ 750 g or < 27 weeks' gestational age enrolled in the NICHD Neonatal Research Network RCT of cycled or continuous phototherapy. Infants will randomize 1:1 to reduced or usual dose lipid assignment during the first 2 weeks after birth and stratified by phototherapy assignment. Free fatty acids and UB will be measured daily using a novel probe. BAER testing will be performed at 34-36 weeks postmenstrual age or prior to discharge. Blinded neurodevelopmental assessments will be performed at 22-26 months. Intention-to-treat analyses will be performed with generalized linear mixed models with lipid dose and phototherapy assignments as random effects covariates, and assessment for interactions. Bayesian analyses will be performed as a secondary analysis. DISCUSSION Pragmatic trials are needed to evaluate whether lipid emulsion dosing modifies the effect of phototherapy on BN. This factorial design presents a unique opportunity to evaluate both therapies and their interaction. This study aims to address basic controversial questions about the relationships between lipid administration, free fatty acids, UB, and BN. Findings suggesting a reduced lipid dose can diminish the risk of BN would support the need for a large multicenter RCT of reduced versus usual lipid dosing.

Abstract
BACKGROUND Intravenous lipid emulsions (ILEs) provide essential fatty acids during parenteral nutrition (PN). Serious adverse events including death can occur from overdose. We report an accidental overdose in a preterm infant. METHOD On Day 2 of life, a 29-week gestational age (GA) twin was accidentally given 47.5 mL of Intralipid20% (≈3x daily amount) in 50-minutes. RESULTS No apparent clinical deterioration occurred, although blood samples were lipaemic. Outcomes at 2 years corrected GA were similar to that of his twin. Service changes were made to infusion packaging and administration to avoid similar errors. CONCLUSIONS Medication errors in neonates are unfortunately common. Published articles usually focus on poor outcomes, which can increase the distress for parents of children where errors have occurred. Publishing the full spectrum of outcomes instead allows parents and professionals to be aware of all possibilities and lessons learnt, even if serious harm was avoided.

Abstract
Preterm and critically ill infants are at risk for hypertriglyceridemia (HTG). Common risk factors for HTG include prematurity, intravenous lipid emulsion dose and oil composition, reduced lipoprotein lipase activity, fetal growth restriction, sepsis, and renal failure. Despite these risk factors, clinicians lack a universally agreed upon definition for HTG and evidence-based approach to HTG management. This review provides a detailed overview of triglyceride and intravenous lipid emulsion metabolism and how this relates to specific HTG risk factors, along with some practical considerations for managing HTG in the neonatal population.

Abstract
Preterm neonates display a high risk of postnatal malnutrition, especially at very low gestational ages, because nutritional stores are less in younger preterm infants. For this reason nutrition and growth in early life play a pivotal role in the establishment of the long-term health of premature infants. Nutritional care for preterm neonates remains a challenge in clinical practice. According to the recent and latest recommendations from ESPGHAN, at birth, water intake of 70–80 mL/kg/day is suggested, progressively increasing to 150 mL/kg/day by the end of the first week of life, along with a calorie intake of 120 kcal/kg/day and a minimum protein intake of 2.5–3 g/kg/day. Regarding glucose intake, an infusion rate of 3–5 mg/kg/min is recommended, but VLBW and ELBW preterm neonates may require up to 12 mg/kg/min. In preterm infants, lipid emulsions can be started immediately after birth at a dosage of 0.5–1 g/kg/day. However, some authors have recently shown that it is not always possible to achieve optimal and recommended nutrition, due to the complexity of the daily management of premature infants, especially if extremely preterm. It would be desirable if multicenter randomized controlled trials were designed to explore the effect of early nutrition and growth on long-term health.

Abstract
Background Tenfold or more overdose of a drug or preparation is a dreadful adverse event in neonatology, often due to an error in programming the infusion pump flow rate. Lipid overdose is exceptional in this context and has never been reported during the administration of a composite intravenous lipid emulsion (ILE). Case presentation Twenty-four hours after birth, a 30 weeks’ gestation infant with a birthweight of 930 g inadvertently received 28 ml of a composite ILE over 4 h. The ILE contained 50% medium-chain triglycerides and 50% soybean oil, corresponding to 6 g/kg of lipids (25 mg/kg/min). The patient developed acute respiratory distress with echocardiographic markers of pulmonary hypertension and was treated with inhaled nitric oxide and high-frequency oscillatory ventilation. Serum triglyceride level peaked at 51.4 g/L, 17 h after the lipid overload. Triple-volume exchange transfusion was performed twice, decreasing the triglyceride concentration to < 10 g/L. The infant’s condition remained critical, with persistent bleeding and shock despite supportive treatment and peritoneal dialysis. Death occurred 69 h after the overdose in a context of refractory lactic acidosis. Conclusions Massive ILE overdose is life-threatening in the early neonatal period, particularly in premature and hypotrophic infants. This case highlights the vigilance required when ILEs are administered separately from other parenteral intakes. Exchange transfusion should be considered at the first signs of clinical or biological worsening to avoid progression to multiple organ failure.

Abstract
OBJECTIVE This study aimed to establish neonatal serum triglyceride (TG) level reference ranges during lipid infusion and correlate peak TG with neonatal outcomes. STUDY DESIGN This is a retrospective review of 356 neonates with 696 TG measures obtained in four neonatal intensive care units between 2015 and 2017. TG was evaluated collectively to establish a reference range and a threshold limit. To analyze the effects of a higher TG threshold, neonates were categorized by their peak TG: <180 (TG<180), 180 to 400 (TG180-400), and > 400 mg/dL (TG>400). Univariable and multivariable regression models were constructed to compare peak TG to patient characteristic and clinical outcomes. RESULTS The frequency of TG > 400 mg/dL was 5% and found only in neonates weighing < 1.5 kg. Neonates in the TG180-400 (n = 91) group were significantly lower in birth weight and gestational age, had lower 5-minute APGAR scores, and had increased ventilatory requirement when compared with neonates in the TG<180 (n = 240) group (all p < 0.001). The TG180-400 group had increased risk of severe intraventricular hemorrhage (p = 0.02) and bronchopulmonary dysplasia (p = 0.03). Elevated TG was associated with mortality (odds ratio [OR]: 14.4, p < 0.001) in univariable analysis, but the relationship weakened (OR: 4.4, p = 0.05) after adjusting for comorbidities in multivariable logistic regression. CONCLUSION It is unclear if the adverse outcomes seen in neonates with higher peak TG were due to elevated TG alone, or whether illness severity predicted the increased TG. More prospective studies are needed to further delineate the relationships.

Abstract
(1) Background: Hypertriglyceridemia (HiTG) is a metabolic complication of intravenous lipid emulsions (ILEs) infusion. We aimed to evaluate the influence of HiTG on the respiratory outcome of preterm babies; (2) Methods: We enrolled, in a case-control study, newborns with gestational age <32 weeks or birth weight <1500 g, over a 3-year period. They were divided into cases and controls; cases were defined by the detection of HiTG defined as serum triglycerides (TG) value >150 mg/dL; (3) Results: We enrolled 40 cases and 105 controls. Cases had an increased incidence of bronchopulmonary dysplasia (30.0% vs. 14.3%, p < 0.05) and longer duration of invasive mechanical ventilation (7 days, 95% CI 4-10 days vs. 4 days, 95% CI 1-7 days, p < 0.01) compared to controls. Multivariate analysis confirmed that HiTG independently influenced the duration of invasive mechanical ventilation, also in the subgroups with gestational age ≤28 + 6/7 weeks or birth weight ≤1000 g; (4) Conclusion: Newborns with HiTG related to ILEs had a longer duration of invasive mechanical ventilation. Temporary suspension or reduction in ILEs in the case of HiTG is associated with an improvement of respiratory outcome.

Abstract
BACKGROUND Recently conducted randomised controlled trials (RCTs) suggest that late commencement of parenteral nutrition (PN) may have clinical benefits in critically ill adults and children. However, there is currently limited evidence regarding the optimal timing of commencement of PN in critically ill term and late preterm infants. OBJECTIVES To evaluate the benefits and safety of early versus late PN in critically ill term and late preterm infants. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (5 April 2019), MEDLINE Ovid (1966 to 5 April 2019), Embase Ovid (1980 to 5 April 2019), EMCare (1995 to 5 April 2019) and MEDLINE via PubMed (1966 to 5 April 2019). We searched for ongoing or recently completed clinical trials, and also searched the grey literature and reference lists of relevant publications. SELECTION CRITERIA We included RCTs comparing early versus late initiation of PN in term and late preterm infants. We defined early PN as commencing within 72 hours of admission, and late PN as commencing after 72 hours of admission. Infants born at 37 weeks' gestation or more were defined as term, and infants born between 34 and 36+6 weeks' gestation were defined as late preterm. DATA COLLECTION AND ANALYSIS Two review authors independently selected the trials, extracted the data and assessed the risk of bias. Treatment effects were expressed using risk ratio (RR) and risk difference (RD) for dichotomous outcomes and mean difference (MD) for continuous data. The quality of the evidence was assessed using the GRADE approach. MAIN RESULTS Two RCTs were eligible for inclusion. Data were only available from a subgroup (including 209 term infants) from one RCT in children (aged from birth to 17 years) conducted in Belgium, the Netherlands and Canada. In that RCT, children with medium to high risk of malnutrition were included if a stay of 24 hours or more in the paediatric intensive care unit (PICU) was expected. Early PN and late PN were defined as initiation of PN within 24 hours and after day 7 of admission to PICU, respectively. The risk of bias for the study was considered to be low for five domains and high for two domains. The subgroup of term infants that received late PN had significantly lower risk of in-hospital all-cause mortality (RR 0.35, 95% confidence interval (CI) 0.14 to 0.87; RD -0.10, 95% CI -0.18 to -0.02; number needed to treat for an additional beneficial outcome (NNTB) = 10; 1 trial, 209 participants) and neonatal mortality (death from any cause in the first 28 days since birth) (RR 0.29, 95% CI 0.10 to 0.88; RD -0.09, 95% CI -0.16 to -0.01; NNTB = 11; 1 trial, 209 participants). There were no significant differences in rates of healthcare-associated blood stream infections, growth parameters and duration of hospital stay between the two groups. Neurodevelopmental outcomes were not reported. The quality of evidence was considered to be low for all outcomes, due to imprecision (owing to the small sample size and wide confidence intervals) and high risk of bias in the included studies. AUTHORS' CONCLUSIONS Whilst late commencement of PN in term and late preterm infants may have some benefits, the quality of the evidence was low and hence our confidence in the results is limited. Adequately powered RCTs, which evaluate short-term as well as long-term neurodevelopmental outcomes, are needed.

Abstract
BACKGROUND The ideal nutritive strategy for a neonate with congenital diaphragmatic hernia (CDH) has not been elucidated. The purpose of this study was to investigate the efficacy of early parenteral nutrition (PN) in CDH neonates. METHODS Thirty-five CDH neonates admitted to a single hospital from January 2005 to December 2014 were retrospectively reviewed. For the first 4 years of the study period, neonates received non-early PN (n-EPN) (2005-2008, amino acids [AA] <1.0 g/kg/day, no lipids administered). After the transitional period (TP) (2009-2011, AA 1.0-2.5 g/kg/day, lipid 1.0 g/kg/day), early PN (EPN) (2011-2014, AA ≥3.0 g/kg/day, lipid 1.0 g/kg/day) was performed. We investigated the clinical effect of PN for growth-associated clinical variables and the outcomes. RESULTS The first day of AA administration was late in the n-EPN period (6.0 ± 4.6, 0.0 ± 0.8, 0.1 ± 0.3 ; n-EPN, TP, EPN: in order). The final day of PN (11.0 ± 3.7, 9.2 ± 4.0, 12.4 ± 3.9) and the first day of enteral feeding (4.5 ± 1.9, 4.3 ± 1.4, 4.5 ± 3.2), the first day of full milk feeding (100 mL/kg/day) (10.8 ± 5.4, 9.2 ± 2.3, 11.5 ± 3.5) were statistically equal in every period. The date and body weight at discharge showed no significant differences among the three groups, but the weight-gain rate from birth to discharge was higher in the EPN group than in the n-EPN group (P = 0.023). The rate of inhaled nitric oxide (NO) gas administration and the duration of ventilation showed no significant differences among the three groups. Severe PN-associated liver disease was not noted during the observation period. CONCLUSIONS Early PN for CDH neonates promotes weight gain in the neonatal intensive-care unit. The long-term efficacy and safety of EPN for CDH neonates should be elucidated by additional studies.

Abstract
BACKGROUND Serious morbidity may elevate nutrient requirements and affect adherence to feeding guidelines for very low birth weight (VLBW) infants. An understanding of factors affecting nutrient intakes of VLBW infants will facilitate development of strategies to improve nutrient provision. Our aim was to examine the impact of neonatal morbidity count on achieving recommended nutrient intakes in VLBW infants. METHODS VLBW infants enrolled in the Donor Milk for Improved Neurodevelopmental Outcomes trial (ISRCTN35317141, n = 363) were included. Serious morbidities and daily parenteral and enteral intakes were collected prospectively. RESULTS Median intakes of infants with and without ≥1 morbidity met protein recommendations (3.5-4.5 g/kg/d) by week 2, although not maintained after week 4. Infants with ≥1 morbidity (vs without) were 2 weeks slower in achieving lipid (4.8-6.6 g/kg/d; week 4 vs 2) and energy (110-130 kcal/kg/d; week 5 vs 3) and 1 week slower in achieving carbohydrate recommendations (11.6-13.2 g/kg/d; week 4 vs 3). Adjusted hazard ratios of first achieving recommendations on any given day in infants with any 1 or 2 morbidities were 0.6 (95% confidence interval [CI], 0.5-0.9) and 0.6 (0.4-0.9), respectively, for protein; 0.5 (0.4-0.7) and 0.3 (0.2-0.5) for lipid; and 0.5 (0.4-0.7) and 0.3 (0.2-0.4) for energy. CONCLUSION Morbidity is associated with a decreased likelihood of achieving lipid and consequently energy recommendations. This and the decline in protein intakes after the early neonatal period require further investigation to ensure optimal nutrition in this vulnerable population.

Abstract
BACKGROUND Emerging evidence suggests intakes of protein and energy as early as the first week of life in preterm very low birth weight (VLBW) infants are associated with improved neurodevelopment. In response, many neonatal intensive care units (NICUs) have launched new, more aggressive early feeding guidelines. The aim of this study was to evaluate enteral and parenteral energy and macronutrient intakes during the first postnatal week in VLBW infants admitted to NICUs that have introduced more aggressive early feeding guidelines. MATERIALS AND METHODS Estimated energy and macronutrient intakes were prospectively collected from VLBW infants fed exclusively mother's own milk and/or parenteral nutrition and compared with expert recommendations. Days to reach full enteral feeds (150 mL/kg/d) and discharge anthropometrics were examined. RESULTS By days 6 and 7, median protein and lipid intakes, respectively, reached recommended values (3.5 and 3.0 g/kg/d). However, by day 8, many infants remained below recommended intakes for protein (34%), lipid (34%), carbohydrate (68%), and energy (71%). Late-onset sepsis was associated with a decreased likelihood of reaching full enteral feeds on any given day (hazard ratio, 0.2; 95% confidence interval, 0.1-0.5; P ≤ .0009). There was no significant relationship between week 1 nutrient intakes and anthropometrics at discharge. CONCLUSION Despite the introduction of more aggressive early feeding guidelines and improved energy and nutrient intakes compared with literature values, many VLBW infants remain below recommended nutrition goals in the first week.

Abstract
BACKGROUND Intravenous lipid emulsions (ILEs) were initially developed to provide parenteral nutrition. In recent years, ILE has emerged as a treatment for poisoning by local anesthetics and various other drugs. The dosing regimen for the clinical toxicology indications differs significantly from those used for parenteral nutrition. The evidence on the efficacy of ILE to reverse acute toxicity of diverse substances consists mainly of case reports and animal experiments. Adverse events to ILE are important to consider when clinicians need to make a risk/benefit analysis for this therapy. METHODS Multiple publication databases were searched to identify reports of adverse effects associated with acute ILE administration for either treatment of acute poisoning or parenteral nutrition. Articles were selected based on pre-defined criteria to reflect acute use of ILE. Experimental studies and reports of adverse effects as a complication of long-term therapy exceeding 14 days were excluded. RESULTS The search identified 789 full-text articles, of which 114 met the study criteria. 27 were animal studies, and 87 were human studies. The adverse effects associated with acute ILE administration included acute kidney injury, cardiac arrest, ventilation perfusion mismatch, acute lung injury, venous thromboembolism, hypersensitivity, fat embolism, fat overload syndrome, pancreatitis, extracorporeal circulation machine circuit obstruction, allergic reaction, and increased susceptibility to infection. CONCLUSION The emerging use of ILE administration in clinical toxicology warrants careful attention to its potential adverse effects. The dosing regimen and context of administration leading to the adverse events documented in this review are not generalizable to all clinical toxicology scenarios. Adverse effects seem to be proportional to the rate of infusion as well as total dose received. Further safety studies in humans and reporting of adverse events associated with ILE administration at the doses advocated in current clinical toxicology literature are needed.

Abstract
Several events occurring during the secondary damage of traumatic brain injury (TBI) can cause oxidative stress. F(2)-isoprostanes (F(2)-IsoPs) and F(4)-neuroprostanes (F(4)-NPs) are specific lipid peroxidation markers generated from arachidonic acid and docosahexaenoic acid, respectively. In this study, we evaluated oxidative stress in patients with moderate and severe TBI. Since sedatives are routinely used to treat TBI patients and propofol has been considered an antioxidant, TBI patients were randomly treated with propofol or midazolam for 72 h postoperation. We postoperatively collected cerebrospinal fluid (CSF) and plasma from 15 TBI patients for 6-10 d and a single specimen of CSF or plasma from 11 controls. Compared with the controls, the TBI patients exhibited elevated levels of F(2)-IsoPs and F(4)-NPs in CSF throughout the postsurgery period regardless of the sedative used. Compared with the group of patients who received midazolam, those who received propofol exhibited markedly augmented levels of plasma F(2)-IsoPs, which were associated with higher F(4)-NPs levels and lower total nitrate/nitrite levels in CSF early in the postsurgery period. Furthermore, the higher CSF F(2)-IsoPs levels correlated with 6-month and 12-month worse outcomes, which were graded according to the Glasgow Outcome Scale. The results demonstrate enhanced oxidative damage in the brain of TBI patients and the association of higher CSF levels of F(2)-IsoPs with a poor outcome. Moreover, propofol treatment might promote lipid peroxidation in the circulation, despite possibly suppressing nitric oxide or peroxynitrite levels in CSF, because of the increased loading of the lipid components from the propofol infusion.

Abstract
Extremely low birth weight infants (ELBW) are born at a time when the fetus is undergoing rapid intrauterine brain and body growth. Continuation of this growth in the first several weeks postnatally during the time these infants are on ventilator support and receiving critical care is often a challenge. These infants are usually highly stressed and at risk for catabolism. Parenteral nutrition is needed in these infants because most cannot meet the majority of their nutritional needs using the enteral route. Despite adoption of a more aggressive approach with amino acid infusions, there still appears to be a reluctance to use early intravenous lipids. This is based on several dogmas that suggest that lipid infusions may be associated with the development or exacerbation of lung disease, displace bilirubin from albumin, exacerbate sepsis, and cause CNS injury and thrombocytopena. Several recent reviews have focused on intravenous nutrition for premature neonate, but very little exists that provides a comprehensive review of intravenous lipid for very low birth and other critically ill neonates. Here, we would like to provide a brief basic overview, of lipid biochemistry and metabolism of lipids, especially as they pertain to the preterm infant, discuss the origin of some of the current clinical practices, and provide a review of the literature, that can be used as a basis for revising clinical care, and provide some clarity in this controversial area, where clinical care is often based more on tradition and dogma than science.

Abstract
BACKGROUND Soy-based intravenous fat emulsion (IVFE) is known to cause a rise in pulmonary artery pressure in the preterm infant, thought to be mediated through eicosanoid metabolites of linoleic acid. We compared the effect of soy-based IVFE and an olive-oil-based IVFE containing less than half the content of linoleic acid on pulmonary artery pressure and eicosanoid metabolites in preterm infants receiving parenteral nutrition. METHODS In this pilot study at a regional neonatal intensive care unit (ICU), infants received either a soy-based or olive-oil-based IVFE as part of an otherwise identical feeding protocol. Pulmonary artery pressure and urinary thromboxane B2 and prostaglandin F1 alpha were measured at baseline and maximum lipid infusion. RESULTS There was a greater fall in pulmonary artery pressure in the olive-oil-based IVFE group compared with the soy-based IVFE group. A decrease in urine thromboxane/prostaglandin F1 alpha ratio was seen only in the olive-oil-based IVFE group. CONCLUSIONS In the parenterally fed preterm infant, an olive-oil-based IVFE may have a beneficial effect on pulmonary artery pressure when compared with soy-based IVFE. Effects on pulmonary vascular tone are likely to be mediated through alterations in eicosanoid metabolism. A randomized trial is warranted to compare the effects of different lipid emulsions.

Abstract
BACKGROUND Cyclic parenteral nutrition (PN) is used for both the treatment and prevention of parenteral nutrition-associated liver disease (PNALD). Early initiation of prophylactic cyclic PN may not be well tolerated in young neonates. Our objective was to test the hypothesis that prophylactic cyclic PN initiated prior to the onset of hyperbilirubinemia is associated with younger age at initiation, lower bilirubin levels, and similar rates of adverse events compared to therapeutic cyclic PN initiated after established cholestasis in surgical neonates. METHODS A retrospective review of infants with gastrointestinal disorders requiring surgical intervention who received cyclic PN 2006-2011 was performed. RESULTS Of the 43 infants eligible for analysis, 23 received prophylactic and 20 received therapeutic cyclic PN. Infants in both groups were comparable in demographics, surgical diagnoses, and illness severity. At initiation of cyclic PN, infants with prophylactic cyclic PN were significantly younger in chronologic (P = .003) and postmenstrual age (P = .029). Prophylactic cyclic PN was associated with a significantly lower incidence of hyperbilirubinemia (P = .001), lower maximum conjugated bilirubin (P < .0001), and lower last checked conjugated bilirubin (P = .032) compared to the therapeutic cyclic PN. The incidence of hypoglycemia, hyperglycemia, and hypertriglyceridemia was similar for the 2 groups. CONCLUSIONS There may be a potential benefit to initiating cyclic PN prior to the development of hyperbilirubinemia in surgical neonates. Early initiation of prophylactic cyclic PN does not appear to increase the risk for adverse events.

Abstract
BACKGROUND Intravenous lipid emulsion (IVLE) is an integral part of the total parenteral nutrition (TPN) regimen in neonates. The use of IVLE during sepsis is the subject of controversy because it may interfere with phagocytosis of microbes by macrophages and may lead to significant hypertriglyceridemia. OBJECTIVE This paper aims to study the rate of clearance of bacteria in relation to dose of IVLE administered to preterm infants with blood stream infections (BSIs). METHODS Preterm infants (mean gestational age ± SD, 32.0 ± 2.5 weeks) with culture-proven BSI and receiving TPN were randomized to two groups. The first group (n = 22) was given the usual dose of IVLE according to a standard protocol (starting from 0.5 g kg(-1) day(-1) and gradually increased by 1 g kg(-1) day(-1) to a maximum of 3.5 g kg(-1) day(-1)); in the second group (n = 20), IVLE were restricted at a dose of 1 g kg(-1) day(-1). Samples for blood cultures were withdrawn every 24 h until a negative culture was obtained. CRP was measured daily until its normalization. Serum triglycerides were monitored daily. RESULTS The rate of bacterial clearance was significantly more rapid in the restricted-dose IVLE group compared to the standard-dose group [72 (48-120) versus 144 (72-168) h, p = 0.001]. Daily weight increment was significantly greater in the standard-dose IVLE group compared to the restricted-dose IVLE group [25 (6.9-31.9) versus 0.9 (-3.3-11.7) g, p = 0.0001]. The duration of antibiotic use was significantly reduced in the restricted-dose IVLE group compared with the standard-dose IVLE group (10.0 ± 4.5 vs 14.9 ± 5.1 days; p = 0.003). The durations of TPN, mechanical ventilation, and hospitalization were not significantly different between groups. CONCLUSIONS Restriction of the dose of IVLE to 1 g kg(-1) day(-1) in preterm infants with BSI is associated with earlier negative blood cultures and reduced duration of antibiotic therapy but was associated with a lower daily weight increments.

Abstract
OBJECTIVE To study the efficacy of early high doses parenteral nutrition (PN) versus early low dose with progressive increments PN regimens, we performed a prospective randomized study in very low birth-weight infants. STUDY DESIGN Forty-one appropriate gestational age preterm infants with birth weights ranging from 750-1500 g were randomly assigned into two groups. In Group 1, infants started on 3.0 g/kg/day amino acids (AA) and 3 g/kg/day of 20% lipid; in Group 2, AA and lipid were started on 1 g/kg/day, and advanced over 3 days to a maximum 3 g/kg/day. Blood samples were obtained for AA concentrations before starting of the PN, and at the 7th and 14th days. RESULTS The mean (±SD) birth weight was 1335 g (240), gestational age was 29.7 weeks (1.7) of the study group. The mean body weight and head circumference was similar in the Group 1 and Group 2 at the 14th postnatal days. There was no difference in the blood levels of triglyceride, blood urea nitrogen, creatinine, ammonia, lactat and bicarbonate in the two groups. There was no significant difference in the concentrations of AA except for arginine and asparagine. On day 14, the mean arginine concentrations were significantly higher and asparagine concentrations were lower in Group 2. CONCLUSION Although earlier more aggressive administration of AA and fat is not associated with any significant metabolic abnormalities, growth rates and plasma AA concentrations of the infants were similar to infants who AA and lipid given lower in the first day of life.

Abstract
BACKGROUND Preterm infants need high amounts of calcium and phosphorus for bone mineralization, which is difficult to obtain with parenteral feeding due to the low solubility of these salts. The objective of this study was to evaluate the physicochemical compatibility of high concentrations of calcium associated with organic phosphate and its influence on the stability of AIO admixtures for neonatal use. METHODS Three TPN admixture formulas were prepared in multilayered bags. The calcium content of the admixtures was adjusted to 0, 46.5 or 93 mg/100 ml in the presence of a fixed organic phosphate concentration as well as lipids, amino acids, inorganic salts, glucose, vitamins and oligoelements at pH 5.5. Each admixture was stored at 4 degrees C, 25 degrees C or 37 degrees C and evaluated over a period of 7 days. The physicochemical stability parameters evaluated were visual aspect, pH, sterility, osmolality, peroxide formation, precipitation, and the size of lipid globules. RESULTS Color alterations occurred from the first day on, and reversible lipid film formation from the third day of study for the admixtures stored at 25 degrees C and 37 degrees C. According to the parameters evaluated, the admixtures were stable at 4 degrees C; and none of them presented precipitated particles due to calcium/phosphate incompatibility or lipid globules larger than 5 mum, which is the main parameter currently used to evaluate lipid emulsion stability. The admixtures maintained low peroxide levels and osmolarity was appropriate for parenteral administration. CONCLUSION The total calcium and calcium/phosphorus ratios studied appeared not to influence the physicochemical compatibility and stability of AIO admixtures.

Abstract
Total parenteral nutrition (TPN) is a necessary form of nutrition in neonates with functional or anatomical disruption of the digestive tract. However, laboratory and human investigation have shown that exposure of the TPN solution to light causes the formation of peroxides and other degradation products that are quantifiable in experimental TPN solutions, laboratory animals, and neonates. Premature neonates are at a higher risk for the development and progression of peroxide damage due to their relative lack of antioxidant and free radical scavenger reserves. Furthermore, cell damage seen in a number of neonatal disease states is exacerbated by the presence of peroxides that are generated via intrinsic pathologic processes and from exogenous sources such as TPN. Numerous studies show that the formation of TPN photodegradation products can be slowed or prevented by the application of various light protection mechanisms. While it is not yet known if minimizing TPN associated photodegradation byproducts has a significant direct effect on preventing or mitigating the overall clinical course of some neonatal disease states, it is becoming increasingly clear that light protecting TPN can avoid specific metabolic complications in neonatal patients. It is prudent to implement mechanisms that prevent photodegradation of TPN components from the manufacturer source to the point of patient administration.

Abstract
The introduction of new modalities of treatment for the very premature infant and advanced life-support systems have led to a decrease in the neonatal mortality rate, and a consequent increase in the population of the tiniest survivors. Many premature infants that survive their neonatal intensive care unit stay have permanent injury to their vital organs including eyes, lungs, brain, and gastrointestinal tract, causing them to have lifelong disabilities. Whether these injuries are a result of their prematurity, or are caused by the life-support systems and treatments is a subject of much dispute. This article explains the process of iatrogenicity and separates the iatrogenic problems that are preventable from those that are currently unpreventable.

Abstract
OBJECTIVE To evaluate plasma clearance of lipid injectable emulsions packaged in either glass or plastic containers in neonates from 2 7-month periods, 1 year apart. STUDY DESIGN Clinical records from June 1 to December 31, 2003 (glass [G] period) and the same months in 2004 (plastic [P] period) were assessed. Neonates who received lipid injectable emulsions were studied. Lipid container (glass vs plastic) was the independent variable. RESULTS Of the 197 patients studied, 122 (G, 50/81; P, 72/116) had evaluable triglyceride (TG) levels, for an overall rate of 62%. Only birth weight (G, 1.09 +/- 0.32 kg vs P, 1.23 +/- .45 kg) and birth length (G, 36.4 +/- 3.5 cm vs P, 37.9 +/- 3.5 cm) were significantly different between the 2 groups (P = .047 and .028, respectively). There were no differences in the day of life on which lipid injection was started, the lipid dose, or the timing of TG measurements. The incidence of hypertriglyceridemia was significantly higher in the P period (G, 3/50 vs P, 19/72; P = .004). CONCLUSIONS Administration of the same lipid formulation in plastic bags compared with glass containers is associated with higher rates of hypertriglyceridemia. The poorer clearance of lipids could be due to a higher proportion of large-diameter fat globules in plastic bags compared with those in glass containers.

Abstract
PURPOSE OF REVIEW Lipid emulsions are crucial for providing essential fatty acids and energy in infants and children requiring parenteral nutrition. There is ongoing debate about the optimal composition of lipid emulsions and the optimal timing for introducing lipids to the parenteral nutrition of premature infants in order to enhance the benefits and to minimize the risk of complications. RECENT FINDINGS Several studies have investigated the effects of early compared with late administration of lipid emulsions. A meta-analysis demonstrated that early introduction of lipid emulsions does not improve short-term growth or prevent morbidity and mortality in preterm infants. On the other hand, early introduction of lipid emulsions was not shown to increase the risk of complications. A number of studies have investigated the effects of different fatty acid compositions in lipid emulsions on peroxidation. In-vitro findings suggest that lipid peroxidation is related to the polyunsaturated fatty acid content and inversely related to the alpha-tocopherol/polyunsaturated fatty acid ratio of the fat emulsion. The composition of lipid emulsions has also been shown to influence fatty acid metabolism. A mixture of medium-chain and long-chain triglycerides seems to enhance the incorporation of essential fatty acids and long-chain polyunsaturated fatty acids into circulating lipids when compared with an emulsion containing only long-chain triglycerides. SUMMARY Although the composition of lipid emulsions has been demonstrated to influence peroxidation and fatty acid metabolism, outcome studies are needed to confirm advantageous effects.

Abstract
BACKGROUND Lipids are essential components of parenteral nutrition for preterm infants. Parenteral lipids can be administered through a peripheral vein, and their early introduction offers the potential advantages of increasing energy intake and providing essential fatty acids and fat soluble vitamins. Concerns have been raised about potential adverse effects including chronic lung disease (CLD), increase in pulmonary vascular resistance, impaired pulmonary gas diffusion, bilirubin toxicity, sepsis and free radical stress. OBJECTIVES To determine the safety and efficacy of 'early' (</= 5 days after birth) introduction of lipids to parenterally fed preterm infants. SEARCH STRATEGY Eligible studies were identified by searching MEDLINE (December 2004), EMBASE 1980 - 2004, Oxford Database of Perinatal Trials, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 4, 2004) and CINAHL (December 1982 - December 2004). Abstracts of the Society for Pediatric Research were hand searched from 1980 to 2004 inclusive. No language restrictions were applied. SELECTION CRITERIA All randomised or quasi randomised controlled trials comparing 'early' versus 'no early' introduction of lipids to preterm infants. DATA COLLECTION AND ANALYSIS Data were sought regarding effects on growth and risk of CLD or death, other respiratory morbidities including duration of respiratory support, duration of supplemental oxygen, the need for home oxygen, pneumothorax (PTX), pulmonary haemorrhage and pulmonary interstitial emphysema (PIE), >/= stage 2 necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP), patent ductus arteriosus (PDA), sepsis, intraventricular haemorrhage (IVH), clinically significant thrombocytopenia and significant jaundice. Methodological quality of eligible studies was assessed according to allocation concealment, blinding of intervention, blinding of outcome assessment and completeness of follow up. When appropriate, meta-analysis was conducted to provide a pooled estimate of effect. For categorical data the Typical relative risk (RR), Typical risk difference (RD) and number needed to treat (NNT) with 95% confidence intervals (CI) were calculated. Continuous data were analysed using weighted mean difference (WMD). MAIN RESULTS Five studies (n = 397) were included in the review. All studies compared the effectiveness and safety of 'early' introduction versus 'no early' introduction of lipids in preterm infants. The timing of introduction of 'early lipids' ranged from < 12 hours after birth to day five of life. The timing of introduction of lipids in the 'no early' lipid group ranged from day six after birth to day 14 after birth. The initial dose ranged from 0.5 - 1 g/kg/day with gradual daily increments up to a maximum of 2.5 - 3.5 g/kg/day. For the primary outcomes (growth, death and CLD), there was no statistically significant difference between the 'early' lipid and 'no early' lipid groups. Days to regain birth weight: [WMD 0.59 (95% CI -2.41, 3.58); two trials; N = 71]. Rate of weight gain (g/day) during period of hospital stay: [MD -2.40 (95% CI -5.30, 0.50); one trial; N = 129]Death (irrespective of time): [Typical RR 1.04 (95% CI 0.69, 1.56); Typical RD 0.01 (95% CI -0.07, 0.08); five trials; N = 397]Neonatal deaths: [Typical RR 1.35 (95% CI 0.78, 2.34); Typical RD 0.05 (95% CI -0.04, 0.13); four trials; N = 268].CLD: [Typical RR 1.10 (95% CI 0.81, 1.49); Typical RD 0.04 (95% CI -0.09, 0.17); two trials; N = 193]. For the secondary outcomes of other respiratory morbidities including duration of respiratory support, duration of supplemental oxygen, PTX, pulmonary haemorrhage, PIE, NEC, ROP, PDA, sepsis, IVH and significant jaundice, there were no statistically significant differences between 'early' and 'no early' lipid groups. AUTHORS' CONCLUSIONS No statistically significant effects of 'early introduction' of lipids on short term nutritional or other clinical outcomes, either benefits or adverse effects, were demonstrated in the studies reviewed. Based on the currently available evidence, 'early' initiation of lipids (</= 5 days after birth) can not be recommended for short term growth or to prevent morbidity and mortality in preterm infants.

Abstract
Deleterious microcirculatory effects of Intralipid (IL) infusion may be caused by hemorheological or vascular effects. The aim of this investigation was to study vascular and hemorheological effects of IL in preterm and fullterm neonates and children. Ten preterm newborns, 10 fullterm neonates, and 10 children received an initial infusion of IL (0.6 g/kg) over 4 h. Calf blood flow (venous occlusion plethysmography), blood pressure (Dinamap), whole blood and plasma viscosity (capillary viscometer), red blood cell deformability (rheoscope), and erythrocyte aggregation (aggregometer) were measured before and after administration of IL. Plasma triglyceride levels showed the greatest increase in preterm infants. Whole blood viscosity decreased by about 10% in all three groups because of a similar reduction in hematocrit. Red blood cell aggregation decreased by about 20% after IL infusion. Blood pressure rose by 10%, and peripheral blood flow declined by about 10% in the three groups. Vascular hindrance, a calculation of blood pressure divided by blood flow and viscosity, was raised by about 20%, suggesting marked vasoconstriction of peripheral arteries. Vasoconstriction rather than hemorheological changes during infusion of IL may play a crucial role in the pathogenesis of circulatory alterations in parenterally-fed neonates.

Abstract
BACKGROUND The aim of the study was the evaluation of the effect of methohexital during chest tube removal (CTR) in neonates. METHODS Evaluation was based on the degree of sedation (grades 1-4) and relaxation (grades 1-4) and trends in vital signs heart rate, mean arterial blood pressure (MAP), oxygen saturation at time points (-10, -5, -3, -1, 0, 1, 3, 5, and 10 min) before and after administration of methohexital. A multidimensional pain scale [Leuven Neonatal Pain Scale (LNPS)] was used to evaluate pain expression. Effective sedation and relaxation (grade >2) would enable the physician to perform CTR without difficulties. Paired Wilcoxon was used to compare vital signs and pain expression before and after the procedure. RESULTS Twenty-two procedures in 22 infants were recorded. Eleven infants were ventilated and 21 infants were having intravenous analgesics during CTR. Birth weight was 2645 g (range 1235-4500 g). Postnatal age was 6 days (range 1-80 days). Methohexital had no effect on ventilatory weaning, MAP or oxygen saturation. Heart rate increased from 144 (49) to 162 (43) (P = 0.012) b.min(-1). Sedation and relaxation were effective (>grade 2) and lasted for <5 min. No major side effects were documented. Adequate analgesia by LNPS was more difficult to evaluate as clinical pain evaluation was not feasible during full muscular relaxation. CONCLUSIONS Administration of methohexital for CTR resulted in adequate sedation and relaxation without major side effects in neonates. This approach should be compared with other strategies.

Abstract
We report on the use of methohexital during elective neonatal direct current cardioversion. In contrast with the available data on cardiac management in neonates with supraventricular tachycardia and the guidelines on anaesthetic management during cardioversion in adults, data on anaesthetic management in neonates are still lacking. Methohexital might be an option for procedural sedation and anaesthesia during elective cardioversion in neonates.

Abstract
To examine the effects of altering the fatty acid (FA) composition of intravenous (IV) lipid emulsions on pulmonary vascular resistance (PVR) and thromboxane production, we studied three groups of newborn piglets after three days of either sow's milk (milk), or total parenteral nutrition (TPN) with either iv soy bean oil (SBO, 52% n-6 and 8% n-3 FA) or fish oil (FO, 5% n-6 and 51% n-3 FA) emulsions. At baseline, and during hypoxia at 20 min and 2 h, cardiac output (Q) was measured, PVR calculated and plasma levels of a prostacyclin metabolite (6-keto-PgF1α) and thromboxane B2 (TxB2) were measured. Fatty acid composition of the lung phospholipids was analyzed. There was an exaggerated increase in PVR and decrease in Q during prolonged hypoxia in the TPN-SBO group as compared with the other two groups. There was no difference in PVR and Q between the milk and TPN-FO groups. FA of lung phospholipids reflected the high dietary level of long chain n-3 FA in the TPN-FO group. However, no differences in plasma levels of 6-keto-PgF1α or TxB2 were found. Intravenous emulsions made from SBO reduced cardiac output and increased pulmonary vascular resistance in the hypoxic newborn piglet, whereas iv FO emulsions did not. When subjects with pulmonary hypertension are receiving TPN iv SBO may be detrimental; iv FO may be beneficial, giving similar responses as in a milk-fed subject.Key words: total parenteral nutrition, fish oil, pulmonary hypertension, lipid emulsion, fatty acids.Key words: total parenteral nutrition, fish oil, pulmonary hypertension, lipid emulsion, fatty acids.

Abstract
BACKGROUND Infusion of parenteral solutions containing peroxides may be detrimental to premature infants. Intralipid frequently contains lipid peroxides and undergoes further peroxidation when exposed to light. Peroxidation is inhibited by ascorbate, and we have proposed that administration of peroxides could be minimized by mixing multivitamins with the Intralipid. In contrast, others have reported that multivitamins generate peroxides and have advised against mixing them with lipid. Our objective was to assess whether light-dependent reactions in parenteral solutions containing MVI Pediatric (MVIP) generate hydrogen peroxide and establish whether addition of multivitamins to Intralipid is beneficial or detrimental. RESULTS We were unable to make accurate peroxide measurements in MVIP using the ferrous oxidation of xylenol orange (FOX) assay, even though others have used it for this purpose, because of interference by ascorbate. Therefore oxygen release on adding catalase was measured to assay for hydrogen peroxide. Freshly reconstituted solutions contained 250 to 500 micromol/L hydrogen peroxide, and this increased dramatically in ambient light. This is presumably due to light-dependent, riboflavin-catalyzed reduction of oxygen by ascorbic acid. The rate of peroxide generation was less for MVIP diluted in Intralipid than in dextrose solution. CONCLUSIONS Taken together with our previous findings, we conclude that multivitamins protect Intralipid against lipid peroxidation, but light-dependent hydrogen peroxide production and ascorbate loss occur. These latter changes are less than for multivitamins in other total parenteral nutrition solutions, so there is an advantage in mixing multivitamins with Intralipid. However, prevention of ascorbate loss and hydrogen peroxide formation in any multivitamin solution requires protection of the delivery system from light.

Abstract
Intravenous lipid emulsions often provide substance for the very low-birth weight or extremely low-birth weight infant that need total parenteral nutrition. The process used in this type of treatment as well as the effects of such treatment are discussed at length in this article. Some of the main compounds of representative lipid emulsions are listed and evaluated and the benefits and consequences of their use are presented.

Abstract
There is a growing body of evidence that early nutritional practices may affect short-term growth and developmental outcome. In addition, they may play a role in determining adult health and disease. There is much that needs to be learned about safe and efficacious nutrient administration in the ELBW population; about techniques to assess the effect of different nutritional strategies; and about the long-term effects of these regimen or development outcome, growth, and disease.

Abstract
Lipids are structural components of all tissues and are indispensable for cell membrane synthesis. The brain, retina, and other neural tissues are particularly rich in LCPUFAs, affecting neural structural development and function. LCPUFAs serve also as specific precursors for eicosanoid production (prostaglandins, prostacyclins, thromboxanes, and leukotrienes). These autocrine and paracrine mediators are powerful regulators of numerous cell and tissue functions (e.g., thrombocyte aggregation, inflammatory reactions, and leukocyte functions, vasoconstriction and vasodilatation, blood pressure, bronchial constriction, uterine contraction). Dietary lipid intake affects cholesterol metabolism at an early age and is associated with cardiovascular morbidity and mortality in later life. Over recent years, the role of fatty acids in modulating signal transduction and regulating gene expression have been described, emphasizing the complex of fatty acid effects. Dietary fatty acids, especially LCPUFA, can have significant effects in the modulation of developmental processes affecting the clinical outcomes of extremely premature infants.
