Poor weight gain observed in preterm infants who were fed expressed breast milk compared with those fed a cows' milk formular prompted a detailed study of early postnatal growth in preterm infants fed these two milks. 68 infants were divided into two categories by gestational age at birth (i) 28-32 weeks (n=28), (ii) 33-36 weeks (n=40). They were randomly allocated to a feed of expressed breast milk or a milk formula (Ostermilk 1). Rates of weight gain, linear growth, and head circumference growth were evaluated over two periods: birth-1 month, 1-2 months. The younger group who were fed breast milk showed slower overall growth rates over the first month than those fed formula. In the second month, and for the older infants over both of the 2-monthly periods, growth rates were similar in the two feeding regimens. It is concluded that expressed breast milk is inadequate for the growth of very immature preterm infants during early postnatal life.
与喂食牛奶配方奶的早产儿相比,喂食挤出来的母乳的早产儿体重增加不佳,这促使人们对喂食这两种奶的早产儿出生后的早期生长情况进行详细研究。68名婴儿根据出生时的孕周分为两类:(i)28 - 32周(n = 28),(ii)33 - 36周(n = 40)。他们被随机分配到喂食挤出来的母乳或牛奶配方奶(Ostermilk 1)组。在两个时间段评估体重增加、线性生长和头围生长速率:出生至1个月、1至2个月。喂食母乳的较年轻组在第一个月的总体生长速率比喂食配方奶的组慢。在第二个月,以及对于较年长的婴儿在这两个两个月的时间段内,两种喂养方式的生长速率相似。得出的结论是,挤出来的母乳在早产儿出生后的早期生活中不足以满足极不成熟的早产儿的生长需求。
