本文通过我院近二年来纠正524例异常性胎位的临床总结,对于外例转术与胸膝卧位法进行了对比观察,认为胸膝卧位法虽有其安全的一面,但成功率较低,尤其是妊娠32周后成功率仅占40%,若继续使用此法;则易失去外倒转术的有利时机。而外倒转术在妊娠38周后成功率仍在80%以上,即使到了妊娠足月或临产早期也能使臀位转成头位。因此,提出外倒转术是降低胎位性难产的较佳方法。
This article through our hospital in the past two years to correct the 524 cases of abnormal fetal clinical summary, for cases of surgery and chest thoracic and supine position were compared, that chest and supine position method although its safety, but the success rate Low, especially after 32 weeks of pregnancy, the success rate of only 40%, if you continue to use this method; is likely to lose the favorable timing of external inversion surgery. The external inversion surgery in 38 weeks after pregnancy, the success rate is still above 80%, even in full-term pregnancy or early labor can make the breech into head position. Therefore, the proposed external inversion surgery is to reduce the fetal dystocia better method.
