1994年3月至1995年5月收住早产及低体重儿143例,有并发症者87例,成活123例。观察早期喂养状况与预后。生后24小时内开始喂养的占69.9％,入量不足以静脉液体补充。本组静脉补液平均6天(2～33天)。资料经逻辑回归分析发现:体温低于35℃>2天,静脉补液或应用抗生素>7天,鼻饲奶残余量超常或吸氧时间>3天等与喂养耐受不良关系密切。本组生理体重下降为出生体重的7％～10.5％,持续体重下降日龄为6.24±2.1。成活儿的92.6％于生后7天体重回升,至出院前80％婴儿恢复出生体重。恢复出生体重日龄≤34周者为10.6±2.40,≥35周者为8.9±2.1。每日公斤体重增长量≤32周者为14.4±8.3g,33～34周者为12.4±6.2g。本组死亡20例,其中≤32周的病死率最高为45％～50％,小于胎龄儿偏高,≥33周病死率为4％～8％。
From March 1994 to May 1995, 143 cases of premature and low birth weight children were enrolled. There were 87 cases of complications and 123 survived. Observe early feeding status and prognosis. 69.9% started feeding within 24 hours after birth, the amount of insufficient intravenous fluid supplement. This group of intravenous rehydration average of 6 days (2 to 33 days). Data logistic regression analysis found that: body temperature below 35 ℃> 2 days, intravenous fluids or antibiotics> 7 days, residual nasal milk residue or oxygen inhalation time> 3 days and feeding tolerance closely related. The physiological weight of this group decreased to 7% ~ 10.5% of the birth weight and the continuous weight loss day was 6.24 ± 2.1. 92.6% of surviving children rebounded after 7 days, and 80% of infants recovered before birth. Restoration of birth weight days ≤ 34 weeks were 10.6 ± 2.40, ≥ 35 weeks were 8.9 ± 2.1. Daily body weight gain of ≤ 32 weeks was 14.4 ± 8.3g, 33 ~ 34 weeks were 12.4 ± 6.2g. The group died of 20 cases, of which ≤ 32 weeks of the highest case fatality rate of 45% to 50%, less than gestational age children high, ≥ 33 weeks mortality was 4% to 8%.
