Insights
Infants with gastroschisis often experience delayed full enteral nutrition and poor growth. Preterm infants are at higher risk, and aggressive feeding may contribute to these outcomes.
Area of Science:
- Neonatalogy
- Pediatric Surgery
- Nutritional Science
Background:
- Gastroschisis is a congenital defect requiring complex nutritional management.
- Optimizing enteral nutrition and growth is critical for infant outcomes.
Purpose of the Study:
- To identify in-hospital factors linked to delayed full enteral feeding in gastroschisis.
- To evaluate the longitudinal growth patterns of infants with gastroschisis.
Main Methods:
- Retrospective single-center study of 52 infants with gastroschisis over 13.5 years.
- Data collected on demographics, nutrition, growth, and outcomes.
- Linear regression analysis to determine factors associated with feeding intolerance and growth.
Main Results:
- Median time to full feeds was 22 days; longer time correlated with increased hospital stay and weight gain.
- Preterm birth was negatively associated with in-hospital weight gain.
- 35% of infants had weight below the 5th percentile, with 67% of these being preterm.
Conclusions:
- Many infants with gastroschisis exhibit poor growth, potentially exacerbated by aggressive feeding advancement.
- Preterm infants with gastroschisis face a greater risk of suboptimal growth.
Objectives:
1) To investigate in-hospital factors associated with delayed tolerance of full volume enteral nutrition and 2) To assess longitudinal growth in a contemporary population of infants with gastroschisis.
Design:
Retrospective single-center study of all infants with gastroschisis Setting: Level III neonatal intensive care unit in a free-standing Children's Hospital Duration: 13.5 years
Materials & Methods:
Detailed data regarding demographics, nutritional support, growth, and infant outcomes was collected for all infants with gastroschisis. Linear regression was used to investigate in-hospital factors associated with feeding intolerance and poor growth.
Results:
For 52 infants, the median gestational age at birth was 36 weeks, the median postnatal age to achieve full feeds was 22 days, and median in-hospital weight gain was 18 gm/day. With linear regression, there was a positive association between time to full feeds and both hospital length of stay (adjusted R2=0.503, p < 0.0001) and (unexpectedly) in-hospital weight gain (adjusted R2=0.125, p=0.0248). There was a negative association between in-hospital weight gain and preterm birth (adjusted R2=0.125, p=0.0356). For infants with longitudinal growth data, 35% had a weight < 5th percentile (of whom 67% were preterm).
Conclusions:
Many infants with gastroschisis have poor growth before and after hospital discharge. Aggressive feeding advancement may be a contributing factor to this finding and preterm infants may be at greater risk for poor growth than term infants.
