臀产式致婴儿死亡的主要原因有三:一是胎膜早破、滞产,二是脐带脱垂,三是胎头娩出困难。近20年来,日本的某些妇产科学者在不断改进臀位助产技术中使婴儿死亡率由30%下降到0.22%,几乎与头产式婴儿死亡率(0.29%)相当;且母婴罹患率明显下降,其中必有经验可以借鉴。笔者复习近年有关日文文献,综述几个关键问题,意在取其所长,补我之短。一、预防胎膜早破和脐带脱垂的几种方法——所谓船式气球水囊的应用在臀产式中前期或早期破膜约占30～60%,较之头先露多若干倍。其中又以单足位(62.5%)>双足位(43.5%)>全臀位(26.7%)>单臀位
Hip birth caused by three major causes of infant mortality: First, premature rupture of membranes, prolonged labor, and second, umbilical cord prolapse, the third is the first childbirth difficulties. In the past two decades, some Japanese gynecologists have reduced infant mortality from 30% to 0.22% with continuous improvement of breech midwifery technology, which is almost equivalent to that of the firstborn infant (0.29%); and maternal and child Attack rate decreased significantly, of which there must be experience can learn from. I review the recent Japanese literature, review a few key issues, intended to take its director, make up for me short. First, the prevention of premature rupture of membranes and umbilical cord prolapse of several methods - the so-called balloon-type balloon in the hip production in pre-or early rupture of membranes accounted for about 30 to 60%, compared with the first several times more than the first show .
