External cephalic version (ECV) was performed in 524 single pregnancies. The version was successful in 38.4%. Success is mainly influenced by parity, quantity of amniotic fluid and maternal weight. An emergency cesarean section was necessary in 0.6% because of fetal bradycardia. Compared to controls the ECV was not associated with the increase of a premature rupture of membranes, complications with umbilical cord or transfer of the child to the paediatric department. Also there was no difference in the pH or Apgar-ranges. One fetal death was diagnosed 17 days after ECV, the reason therefore remained unclear. There are existing a few other reports with similar cases. We conclude that ECV is a appropriate trial to convert the fetus into cephalic presentation, but because of possible complications precautions must be taken, e.g. that means to carry out the trial under conditions which allow immediate cesarean section and a frequent follow up of the woman until delivery.
对524例单胎妊娠进行了外倒转术（ECV）。倒转术成功率为38.4%。成功主要受产次、羊水量和孕妇体重影响。因胎儿心动过缓，0.6%的病例需要紧急剖宫产。与对照组相比，ECV与胎膜早破增加、脐带并发症或将婴儿转至儿科无关。pH值或阿氏评分范围也无差异。在ECV术后17天诊断出1例胎儿死亡，死因不明。还有其他一些类似病例的报告。我们得出结论，ECV是将胎儿转为头先露的一种合适尝试，但由于可能出现并发症，必须采取预防措施，例如在允许立即剖宫产的条件下进行该操作，并在分娩前对孕妇进行频繁随访。
