Early enteral feeding during hypothermia for neonatal HIE shows no GI adverse event link
This retrospective cohort study at a single Chinese hospital included 94 consecutive neonates with moderate to severe hypoxic-ischemic encephalopathy (HIE) undergoing therapeutic hypothermia. The intervention was early enteral feeding (EEF) initiated during hypothermia or rewarming (n=48), compared to delayed enteral feeding (DEF) initiated post-rewarming (n=46).
The primary outcome was gastrointestinal adverse events (GIAEs). After adjustment for confounders, EEF was not independently associated with GIAEs (OR = 0.75, 95% CI: 0.23–2.44, P = 0.636). Secondary outcomes showed EEF was associated with reduced time to feeding initiation, shorter parenteral nutrition duration, and lower hospitalization costs (all P < 0.05).
Safety was assessed via GIAEs, with no significant difference between groups after adjustment. Serious adverse events, discontinuations, and tolerability were not reported.
Key limitations include the single-center retrospective design, potential confounding by indication, and small sample size. The study highlights the challenge of confounding in interpreting feeding timing associations.
Practice relevance is restrained; findings are observational and do not imply causation. Clinicians should consider these associations cautiously in this specific population.
