Absence or reversal of end diastolic flow (AREDF) in the umbilical artery is associated with poor outcome, and elective premature delivery is common. Feeding these infants is a challenge. They often have poor tolerance of enteral feeding, and necrotising enterocolitis may develop. This review explores current practice to see if there is evidence on which to base guidelines. The incidence of necrotising enterocolitis is increased in infants with fetal AREDF, especially when complicated by fetal growth restriction. Abnormalities of splanchnic blood flow persist postnatally, with some recovery during the first week of life, providing justification for a delayed and careful introduction of enteral feeding. Such a policy exposes babies to the risks of parenteral nutrition, with no trials to date showing any benefit of delayed enteral nutrition. Trials are required to determine the optimum timing for introduction of enteral feeds in growth restricted infants with fetal AREDF.
脐动脉舒张末期血流缺失或逆流(AREDF)与不良预后相关,择期早产很常见。喂养这些婴儿是一项挑战。他们通常对肠内喂养耐受性差,可能会发生坏死性小肠结肠炎。本综述探讨了当前的做法,以查看是否有证据可作为指南的依据。胎儿AREDF的婴儿发生坏死性小肠结肠炎的几率增加,尤其是合并胎儿生长受限的情况。出生后内脏血流异常持续存在,在出生后第一周会有所恢复,这为延迟并谨慎引入肠内喂养提供了依据。这种政策使婴儿面临肠外营养的风险,迄今为止尚无试验表明延迟肠内营养有任何益处。需要进行试验以确定在患有胎儿AREDF的生长受限婴儿中引入肠内喂养的最佳时机。
