Abstract

Background: Appropriate post-natal growth remains a mainstay of therapeutic goals for infants with CDH, with the hypothesis that optimizing linear growth will improve survival through functional improvements in pulmonary hypoplasia. However, descriptions of growth and the effect on survival are limited in affected infants.

Objective: Describe in-hospital weight gain related to survival among infants with CDH.

Design/methods: Children's Hospitals Neonatal Database (CHND) identified infants with CDH born ≥34weeks' gestation (2010-14). Exclusion criteria were: admission age>7days, death/discharge age75%ile. Descriptive measures and unadjusted Kaplan-Meier analyses describe the implications of WGV on mortality/discharge.

Results: In 630 eligible infants, median WGV was 4.6g/kg/day. After stratification by WGV [Q1: (n=156; <3.1g/kg/day); Q2-3 (n=316; 3.1-5.9g/kg/day), and Q4 (n=158, >5.9g/kg/day)] infants in Q1 had shortest median length of stay, less time on TPN and intervention for gastro-esophageal reflux relative to the other WGV strata (p

Conclusion: Variable WGV is evident in infants with CDH. Highest and lowest WGV appear to be related to adverse outcomes. Efforts are needed to develop nutritional strategies targeting optimal growth.
