In 16 cases from a total of 36 (44%) the external cephalic version was successful. 18 times the relaxation of the uterus was performed by general anaesthesia with a successrate of 50% and 17 times by Fenoterol with a successrate of 35%. A V-para had a successful external cephalic version without any relaxation of the uterus. In average the external cephalic version was performed in the 39th week of pregnancy. From these 16, in whose case an external cephalic version was successful, there were 6 caesarian deliveries because of fetal indication. From 5 of these 6 caesarian deliveries it was discovered at the time of delivery a complication of the umbilicus. In one case of two massive fetomaternal transfusion the child died. In both cases of fetomaternal transfusion the placenta was located to the anterior wall of the uterus. Therefore we think this location of the placenta is a contraindiction for external cephalic version.
在总共36例中，有16例（44%）外倒转术成功。18次通过全身麻醉使子宫松弛，成功率为50%；17次使用羟苄羟麻黄碱，成功率为35%。一位经产妇未进行子宫松弛就成功实施了外倒转术。外倒转术平均在妊娠第39周进行。在这16例成功进行外倒转术的病例中，有6例因胎儿指征进行了剖宫产。在这6例剖宫产中有5例在分娩时发现了脐部并发症。在1例双胎大量胎儿 - 母体输血病例中，胎儿死亡。在两例胎儿 - 母体输血病例中，胎盘均位于子宫前壁。因此，我们认为胎盘的这种位置是外倒转术的禁忌证。
