【摘要】 目的随着早产地存活率的提高，早产儿喂养不耐受的问题日益显得突出，本文将探讨其可能的原因。方法我们对1996年1月～12月住院的86例出生体重＜2000g的早产儿进行了回顾分析。结果19例出现喂养不耐受占22．1％，主要表现为频繁呕吐、腹胀、胃潴留和奶量不能完成。出生体重≤1500g（占55．6％）、胎龄＜34周（29．4％）以及有窒息史（30％）的患儿容易发生喂养不耐受。结论出生体重≤1500g的早产儿发生喂养不耐受多与胃食管返流、早产儿胃肠道功能不成熟有关，出生体重＞1500g者多有缺氧、感染等疾病。持续胃管喂养和促胃肠动力药物可提高喂养耐受性。更多还原

【Abstract】 Objective To analyse the reason of feeding intolerance which becomes more prominent in survivors of low birth weight infants. Methods We retrospectively reviewed 86 cases of pretermneonates with birth weight below 2000g hospitalized during the year of l996. Results We found l9 ofthem (22. 1 % ) had feeding intolerance as evidenced by frequent vomiting, abdominal distension, gastricresiduals and low feeding volume, mainly occurring in those with birth weight below l500g (55. 6% ),gestation of less than 34 weeks (29. 4% ), and low Apgar score (3O% ). Conclusion The feeding intolerance occurred in neonates of very low birth weight (≤ l500g) had gastroesophageal reflux and gastrointestinal immaturity, while, in those with birth weight over 1500g, it was of ten complicated by hypoxemia and infection. Continuous intragastric feeding and drugs facilitating gastrointestinal motilitytended to be effective.更多还原
