目的分析极低出生体重儿住院期间营养摄入与其体重增长速度的关系。方法回顾性调查2011-2012年在深圳市妇幼保健院住院的极低出生体重儿的临床和营养资料。按体重增长速率将患儿分为低体重增长组、适宜体重增长组和高体重增长组,比较三组的临床营养摄入情况。结果 147例极低出生体重儿的体重增长速度中位数为12.77g/(kg·d),住院时间中位数为48d;高体重和适宜体重增长组的住院天数、静脉氨基酸开始使用时间和达到全肠内营养时间均小于低体重增长组;极低出生体重儿生后第7天、14天、21天和28天肠外营养中的碳水化合物、脂肪和蛋白质的用量呈递减趋势。结论极低出生体重儿住院期间的体重增长速度与营养摄入状况和住院时间密切相关,加强肠内外营养,缩短住院时间有利于促进极低出生体重儿的体重增长。
Objective To analyze the relationship between nutritional intake and weight gain in very low birth weight infants during hospitalization. Methods The clinical and nutritional data of very low birth weight children hospitalized in Shenzhen MCH in 2011-2012 were retrospectively reviewed. According to the rate of weight gain, children were divided into low weight gain group, suitable weight gain group and high weight gain group. The clinical nutritional intake of the three groups was compared. Results The median rate of weight gain of 147 very low birth weight children was 12.77g / (kg · d), the median length of stay was 48 days. The length of hospital stay, the length of hospitalization for intravenous amino acids, The total enteral nutrition time was less than that of low weight gain group. The dosage of carbohydrate, fat and protein in parenteral nutrition of very low birth weight children showed a decreasing trend on the 7th, 14th, 21st and 28th day after birth. Conclusion The body weight growth rate of very low birth weight infants during hospitalization is closely related to the nutritional intake and hospitalization time. Enhancing parenteral nutrition and shortening the hospital stay are good for promoting the weight gain of very low birth weight infants.
