Objective: The objective of this study was to determine the feasibility and safety of enhanced early (PN) (early initiation of intralipids and faster advancement of glucose infusion rate) during the first week of life for very low birth weight (VLBW) preterm infants. Methods: 90 VLBW preterm infants (<32 weeks gestational age at birth) admitted to the University of Minnesota Masonic Children's Hospital between August 2017 and June 2019 were included. Enrolled infants were stratified by gestational age-groups and randomized to either the enhanced nutrition protocol (intervention group) or the standard PN protocol (standard group). Welch's two-sample t tests were used to investigate differences in calorie and protein intake, insulin use, days of hyperglycemia, hyperbilirubinemia, and hypertriglyceridemia, and proportion of bronchopulmonary dysplasia, necrotizing enterocolitis, and death between groups. Results: Intervention and standard groups were similar in baseline characteristics. The intervention group received higher weekly mean caloric intake (102.6 [SD 24.9] kcal/kg/day versus 89.7 [SD 30.2] kcal/kg/day; p = 0.001) and higher mean caloric intake on days of life 2-4 (p < 0.05 for all). Both groups received the recommended protein intake (≥4 g/kg/day). There were no significant differences in safety or feasibility outcomes between groups (all p values >0.12). Conclusion: Utilization of an enhanced nutrition protocol during the first week of life resulted in increased caloric intake and was feasible with no evidence of harm. Follow-up of this cohort is needed to determine if enhanced PN will result in improved growth and neurodevelopment.
