Attainment Targets for Protein Intake Using Standardised, Concentrated and Individualised Neonatal Parenteral Nutrition Regimens

Safe and efficient practice of parenteral nutrition in neonates and children aged 0-18 years - The role of licensed multi-chamber bags

Parenteral nutrition (PN) is recognized as a complex high-risk therapy. Its practice is highly variable and frequently suboptimal in pediatric patients. Optimizing care requires evidence, consensus-based guidelines, audits of practice, and standardized strategies. Several pediatric scientific organizations, expert panels, and authorities have recently recommended that standardized PN should generally be used over individualized PN in the majority of pediatric patients including very low birth weight premature infants. In addition, PN admixtures produced and validated by a suitably qualified institution are recommended over locally produced PN. Licensed multi chamber bags are standardized PN bags that comply with Good Manufacturing Practice and high-quality standards for the finished product in the frame of their full manufacturing license. The purpose of this article is to review the practical aspects of PN and the evidence for using such multi-chamber bags in pediatric patients. It highlights the safety characteristics and the limitations of the different PN practices and provides some guidance for ensuring safe and efficient therapy in pediatric patients.

The Use of Standardized Solutions Instead of Individualized Prescriptions for Parenteral Nutrition on the Neonatal Intensive Care Unit in UZ Brussel: A Feasibility Study

For parenteral nutrition (PN) of newborns, the European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) 2018 guidelines recommend standardized solutions over individual PN (IPN) solutions for most patients. This retrospective study assessed if a shift from IPN to standardized PN was feasible at the UZ Brussel. Using prescription data of 145 neonates, we calculated the nutrient provision for IPN and for standardized PN of the same volumes. We compared the macronutrient intakes with ESPGHAN 2018 recommendations to assess the feasibility. For neonates of a gestational age (GA) <32 or >36 weeks, standardized PN reached recommendations as least as fast as IPN. For neonates with a GA of 32 to 36 weeks, the administration protocol requires further adjustments as amino acid provision was lacking compared to IPN. Overall, the results support the feasibility of a shift from IPN to standardized PN at the UZ Brussel.

Nutritional Strategies for Preterm Neonates and Preterm Neonates Undergoing Surgery: New Insights for Practice and Wrong Beliefs to Uproot

The nutrition of preterm infants remains contaminated by wrong beliefs that reflect inexactitudes and perpetuate old practices. In this narrative review, we report current evidence in preterm neonates and in preterm neonates undergoing surgery. Convictions that necrotizing enterocolitis is reduced by the delay in introducing enteral feeding, a slow advancement in enteral feeds, and the systematic control of residual gastric volumes, should be abandoned. On the contrary, these practices prolong the time to reach full enteral feeding. The length of parenteral nutrition should be as short as possible to reduce the infectious risk. Intrauterine growth restriction, hemodynamic and respiratory instability, and patent ductus arteriosus should be considered in advancing enteral feeds, but they must not translate into prolonged fasting, which can be equally dangerous. Clinicians should also keep in mind the risk of refeeding syndrome in case of high amino acid intake and inadequate electrolyte supply, closely monitoring them. Conversely, when preterm infants undergo surgery, nutritional strategies are still based on retrospective studies and opinions rather than on randomized controlled trials. Finally, this review also highlights how the use of adequately fortified human milk is strongly recommended, as it offers unique benefits for immune and gastrointestinal health and neurodevelopmental outcomes.

Systematic Review on Individualized Versus Standardized Parenteral Nutrition in Preterm Infants

The need for high quality evidence is recognized for optimizing practices of parenteral nutrition (PN). The purpose of the present systematic review is to update the available evidence and investigate the effect of standardized PN (SPN) vs. individualized PN (IPN) on protein intake, immediate morbidities, growth, and long-term outcome in preterm infants. A literature search was performed on articles published in the period from 1/2015 to 11/2022 in PubMed and Cochrane database for trials on parenteral nutrition in preterm infants. Three new studies were identified. All new identified trials were nonrandomized observational trials using historical controls. SPN may increase weight and occipital frontal circumference gain and lower the value of maximum weight loss. More recent trials suggest that SPN may easily increase early protein intake. SPN may reduce the sepsis incidence, but overall, no significant effect was found. There was no significant effect of standardization of PN on mortality or stage ≥2 necrotizing enterocolite (NEC) incidence. In conclusion SPN may improve growth through higher nutrient (especially protein) intake and has no effect on sepsis, NEC, mortality, or days of PN.

A Pre-Post Intervention-Based Study Investigating the Impact of Standardized Parenteral Nutrition at Tertiary Neonatal Intensive Care Unit in Karachi, Pakistan

Introduction

Conventionally, various parenteral nutrition (PN) components are individually administered considering an individual neonate's requirements. More recently, standardized PN (SPN) formulations have been initiated for preterm neonates, which may benefit from the enhanced nutrient supply, less administration and prescription errors, reduced risk of infectious disease, and cost-effectiveness.

Methodology

A multicentered, pre-post intervention-based study was conducted at tertiary neonatal intensive care units (NICUs) in Karachi, Pakistan. Post-graduate residents of neonatology and pediatrics working in NICUs were included in the study, and their perspective was attained regarding PN formulation and a prescription for time consumption, ease, calculation errors, and general feedback. Independent T-test was applied to assess the statistical difference between the pre-and post-implementation of PN formulation for total time required for PN calculation, whereas for the rest of the quantitative variables Mann-Whitney U test was computed.

Results

The total time required to do the entire writing process, calculating and ordering PN, was 17.1±6.9 whereas significantly (p-value of <0.0001) reduced to 10.5±5.7 after implementing SPN prescriptions. Calculation errors were reduced from 32% to 12%, and writing errors were also decreased from 35% to 8% when the standardized parenteral nutritional formulation was applied.

Conclusion

Our findings show that implementing standardized prescriptions in the NICU has improved medication safety, with the most consistent benefit by reducing medication errors and time management. The SPN prescriptions save time for post-graduate residents, physicians, and pharmacists by eliminating previously required repetitive activities and calculations.

Do preterm girls need different nutrition to preterm boys? Sex-specific nutrition for the preterm infant

Boys born preterm are recognised to be at higher risk of adverse outcomes than girls born preterm. Despite advances in neonatal intensive care and overall improvements in neonatal morbidity and mortality, boys born preterm continue to show worse short- and long-term outcomes than girls. Preterm birth presents a nutritional crisis during a critical developmental period, with postnatal undernutrition and growth-faltering common complications of neonatal intensive care. Furthermore, this preterm period corresponds to that of rapid in utero brain growth and development, and the developmental window relating to foetal programming of adult non-communicable diseases, the prevalence of which are associated both with preterm birth and sex. There is increasing evidence to show that from foetal life, boys and girls have different responses to maternal nutrition, that maternal breastmilk composition differs based on foetal sex and that early neonatal nutritional interventions affect boys and girls differently. This narrative review examines the evidence that sex is an important moderator of the outcomes of preterm nutrition intervention, and describes what further knowledge is required before providing nutrition intervention for infants born preterm based on their sex. IMPACT: This review examines the increasing evidence that boys and girls respond differently to nutritional stressors before birth, that maternal breastmilk composition differs by foetal sex and that nutritional interventions have different responses based on infant sex. Boys and girls born preterm are given standard nutritional support which does not take infant sex into account, and few studies of neonatal nutrition consider infant sex as a potential mediator of outcomes. By optimising early nutrition for boys and girls born preterm, we may improve outcomes for both sexes. We propose future studies of neonatal nutritional interventions should consider infant sex.
