Background:
We aimed to describe nutrient intake and growth in infants with gastroschisis and identify factors associated with impaired growth.
Methods:
Retrospective study of neonates who underwent gastroschisis repair from 2010 to 2015. Nutrient intake and weight-for-age z scores (WAZ) were recorded.
Results:
Data from 60 eligible infants with median (Q1, Q3) gestational age of 36 weeks (35, 37) and birth weight 2418 g (2098, 2665) were analyzed. Median WAZ decreased from -0.71 (-1.08, -0.17) at birth to -1.08 (-1.58, -0.63) at discharge (P < .001); 30% experienced a >1.0 decline in WAZ. Parenteral nutrition (PN) was initiated soon after birth, and 14 (23%) patients had severe intestinal failure. Fourteen patients (23%) experienced central line-associated bloodstream infection (CLABSI) at a rate of 5.0 per 1000 catheter days. Factors independently associated with lower discharge WAZ and greater WAZ decline were CLABSI (P = .02) and prematurity (P = .02). By day 7, energy and protein intake were 90-100 kcal/kg/day and 3 g/kg/day, respectively. Median age to achieve enteral autonomy was 36 days (22, 82). Atresias, CLABSI, prematurity, and staged closure were associated with delayed enteral autonomy (P < .01). Among 34 patients with 1-year follow-up, WAZ improved from -1.16 (-1.74, -0.65) at discharge to 0.19 (-0.80, 0.61) at 12 months (P < .001).
Conclusion:
Infants with gastroschisis are dependent on PN and have a significant decline in WAZ during their hospital stay, predicted by prematurity and CLABSI. Efforts to prevent CLABSI and optimize enteral autonomy must be prioritized in this cohort.
