Nutrition Week (Day 5) What a Gastrostomy Tube Means for Cognition

Looking at a retrospective cohort of 194 neonates, a recent study (SR Jadcherla et al. J Pediatr 2017; 181: 125-30) showed that infants discharged with a gastrostomy tube (Gtube) had associated lower cognitive outcomes.

The authors examined discharge milestones along with Bayley Scales of Infant Development (3rd edition) at 18-24 months of age.

Key findings:

  • 60% of infants (n=117) were discharged on oral feedings and 96% remained oral-fed at 1 year.
  • 40% (n=77) were discharged on gastrostomy feedings.31 (40%) remained fully Gtube dependent, 17 (22%) were orally-fed, and 29 (38%) were on oral/gtube combination.
  • Gtube feedings at discharge were a marker for lower cognition (P<0.01), communication (P=0.03) and motor (P<0.01) composite scores at 18-24 months of age.
  • Other factors associated with neurodevelopmental delay included intraventricular hemorrhage, younger gestational age, and bronchopulmonary dysplasia.

My take: This study provides evidence for an expected finding –infants who need gtubes have poorer neurodevelopmental outcomes than infants who do not need gtubes.
