本文收集了年龄2-6月婴儿患婴儿肝炎综合征66例，均B超排除先天性胆道畸形，分为二组，一组为母乳喂养儿，一组为对照人工喂养儿。母乳喂养组患婴儿肝炎综合征23例，发生肝功能衰竭3例，死亡2例，病死率8．7％。而对照组儿患婴儿肝炎综合征43例，发生肝功能衰竭15例，死亡14例，病死率32.6％，两组比较有显著差异（1．96＜u=2．173＜2．58，P＜0.05）。结果提示：母乳对婴儿肝炎综合征预防和治疗有积极意义，母乳是婴儿的最佳天然营养品，因此应积极提倡、推广、支持、促进和保护母乳喂养。 This article collected 66 cases of infantile hepatitis syndrome in infants from 2 to 6 months old, all of whom had congenital biliary malformations after B-ultrasound.
