To determine the mass of colostrum ingested by exclusively breastfed newborn infants during the first 24 hours of extrauterine life.
Milk ingested during the first 24 hours of life by 90 healthy newborn infants was evaluated by use of a scale with high sensitivity. The masses were measured during 8-hour periods. Associations of the mass measured with prenatal and postnatal variables were tested.
The mass of colostrum ingested was evaluated in 307 feedings, with 3.4+/-1 feedings recorded per 8-hour period of observation. Mean gain per feeding was 1.5+/-1.1 g. The daily mass of milk ingested by newborn infants was estimated at 15+/-11 g. This volume did not show a tendency to increase during the first 24 postnatal hours, nor was it related to perinatal or postnatal factors or to breastfeeding time.
During the first 24 hours of life newborns ingested 15+/-11 g of milk.
确定新生儿在宫外生命的头 24 小时内摄入的初乳量。
通过高灵敏度的秤,评估 90 名健康新生儿在生命的头 24 小时内摄入的奶量。在 8 小时期间测量质量。测试测量质量与产前和产后变量的相关性。
在 307 次喂养中评估了初乳的摄入量,每个 8 小时观察期记录 3.4+/-1 次喂养。每次喂养的平均增重为 1.5+/-1.1 克。新生儿每天摄入的牛奶量估计为 15+/-11 克。在最初的 24 个产后小时内,这个量没有增加的趋势,也与围产期或产后因素或母乳喂养时间无关。
在生命的头 24 小时内,新生儿摄入了 15+/-11 克的奶。
