摘要
本文综合分析了两个单位1975年至1992年6月期间442例的多胎妊娠888名围产儿,其中死胎16名,死产13名,新生儿死亡52名,死亡围产儿共81名,国产儿病死率为91.2％‰.本文认为:孕妇合并早产、妊高征、胎膜早破等妊娠并发症走围产儿死亡的主要因素,臀牵引术或内倒转后臀牵引助产者围产儿病死率高。因此对多胎妊娠要加强产前检查和管理,对孕龄大于34周、估计胎儿体重在2000g以上者,适当放宽剖宫产指征,可望降低多胎妊娠围产儿病死率。
From 1975 to June 1992, 888 babics were dclivered in the two hospitals. There were 81 perinatal deaths including 16 fetal deaths, 13 still births, and 52 nconatal deaths. The perinalal mortality was 91. 2‰. The analysis indicated that prernature labour, prcgnarcy induced hypcrtension, and prc-rnature rupture of membrane were unfavourable factors, and pcrinatal mortality was higher in the cases of breech extraction er intemal version followed by breech extrac-tion. The authors suggcstod that antepartum cxamination and managernent should be emphasized for multiple preg-nancy. For those with gestational age older than 34 weeks or estimated fetal weight greater than 2000 grams, perinatal mortality may be redueed by widening the indications for cesarean seetion.
