A significantly greater proportion of infants with gastrostomy-tube feeds at discharge had intrapartum complications, Apgar scores <5 at 5 and 10 minutes, severe rather than moderate HIE, and seizures. They also had a longer hospital stay, prolonged respiratory support and intubated days, and delayed initiation of feeding. Infants discharged on nasogastric feeds all attained oral feeds at a median (IQR) duration of 54 (6-178) days follow-up. Among the 106 (86%) infants with follow-up data, the gastrostomy group had significantly lower median weight and head circumference centiles compared to the others. Criteria for gavage eligibility were met before discharge in 98 (80%) of the cohort; 42% stayed beyond this benchmark.</p><p><strong>Conclusion: </strong> Earlier identification of eventual gastrostomy tube insertion as well as discharge home on nasogastric feedings may reduce duration of hospitalization in infants with HIE. Our data may provide insights to guide practice improvement for enteral feedings in this population.</p><p><strong>Key points: </strong>· In neonatal encephalopathy, impaired oral feedings is common.. · Antepartum complications and HIE severity are associated with gastrostomy insertion.. · Discharge home on gavage feeds could shorten hospital stay..</p>","PeriodicalId":7584,"journal":{"name":"American journal of perinatology","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
