Abstract

Abstract: Background: The optimal timing of supplemental parenteral nutrition (PN) use in the pediatric intensive care unit (ICU) is unclear. We aimed to describe patterns of PN use in the ICU and the association between the timing of PN initiation and macronutrient delivery and anthropometry. Methods: We enrolled patients (aged <18 years) with an ICU stay >3 days were started on PN in the ICU. Initiation within 48 hours of admission was deemed as early, and duration <5 days was deemed as short. We used multivariable analysis to examine the association between PN timing and macronutrient delivery adequacy (percentage of the prescribed target that was actually delivered) and weight‐for‐age z ‐score (WAZ) over hospital stay. Results: Ninety‐five patients were included. Median (interquartile range [IQR]) time to initiate PN was 4 (1, 6) days, and in 33%, PN was initiated early. Median (IQR) PN duration was 8 (5, 14) days, and in 16.8%, duration was short. Median (IQR) adequacies for total energy and protein delivery were 55% (40, 74) and 72% (44, 81) in the early PN group compared with 29% (3, 50) and 31% (4, 47), respectively, in the late PN group ( P < .001). The late PN group had a 0.50‐unit greater decline in mean WAZ compared with the early PN group (95% CI, 0.11–0.89; P = .012). Conclusion: Late PN initiation was associated with significantly lower adequacy of macronutrient delivery and greater decline in WAZ in critically ill children. The relationship between PN timing patient outcomes must be further examined.
