The Effect of Individualized Versus Standardized Parenteral Nutrition on Body Weight in Very Preterm Infants

چکیده
BACKGROUND This study was designed to evaluate whether standardizing total parenteral nutrition (TPN) is at least non-inferior to TPN with individualized composition in premature infants with a gestational age (GA) < 32 weeks. METHODS In this retrospective cohort study, all preterm born in or transferred to Maxima Medical Center (MMC) within 24 hours after birth with a GA < 32 weeks were included. The individualized group (2011) was compared to the partially standardized group (2012) and completely standardized group (2014) consequently. The primary endpoint was difference in growth. Secondary endpoints included differences in electrolyte concentrations. RESULTS A total of 299 preterm were included in this study. When comparing weight gain, the infants in the (partially) standardized group demonstrated significantly (P < 0.05) less weight loss during the first days of life and grew faster subsequently in the following days than the individualized TPN regimen. Furthermore, significant differences in abnormal serum sodium, chloride, calcium, creatinine, magnesium and triglycerides values were demonstrated. CONCLUSION TPN with a (partially) standardized composition revealed to be at least non-inferior to TPN with an individualized composition.

Clinical Factors Affecting Lipid Metabolism and Optimal Dose of Heparin in Preterm Infants on Parenteral Nutrition
PURPOSE Preterm infants on parenteral nutrition are at a relatively high risk for hypertriglyceridemia because they have immature lipoprotein lipase activity. The purpose of this study was to analyze the clinical factors affecting lipid metabolism in preterm infants receiving parenteral nutrition and to evaluate the influence of intravenous heparin on serum triglycerides to determine the adequa...
متن کاملEarly versus Late Trophic Feeding in Very Low Birth Weight Preterm Infants
OBJECTIVE Improved survival of preterm infants, beneficial effects of trophic feeding and limited data on timing management of enteral feeding for very low birth weight preterm infants requires more researches to determine the exact starting time and increased volumes. This study aims to compare early (<48 h) versus late (>72h) trophic feeding with respect to important neonatal outcomes. METH...

متن کاملThe fear of necrotizing enterocolitis versus achieving optimal growth in preterm infants--an opinion.
UNLABELLED Very-low-birthweight (VLBW) infants suffer marked growth delay despite well-intentioned efforts at combining enteral and parenteral nutrition. Fear of necrotizing enterocolitis (NEC) has traditionally influenced neonatologists toward delaying and progressing slowly with enteral feeding, while supporting the infant with parenteral nutrition. Current evidence suggests significant benef...
متن کاملDoes Parenteral Nutrition Influence Electrolyte and Fluid Balance in Preterm Infants in the First Days after Birth?
BACKGROUND New national guidelines recommend more restricted fluid intake and early initiation of total parenteral nutrition (TPN) in very preterm infants. The aim was study the effect of these guidelines on serum sodium and potassium levels and fluid balance in the first three days after birth. METHODS Two cohorts of infants <28 weeks gestational age, born at the Leiden University Medical Ce...
