External cephalic version (ECV) is not a popular procedure in developing countries such as Nigeria. Over a 3-year period, we prospectively studied women who had ECV in a Nigerian University Teaching hospital. Comparative analysis was made between the successful ECV and the unsuccessful ECV groups. Following adequate counselling, Nigerian women were willing to accept an ECV for the singleton term breech. The ECV success rate was 67%. Favourable factors for success were multiparity (Relative Risk, RR 3.8; 95% confidence interval, CI 1.14 - 12.1), flexed breech (RR 2.4; 95% CI 1.02 - 5.7), unengaged breech (RR 4.8; 95% CI 1.3 - 17.2), normal liquor volume (RR 4.8; 95% CI 1.3 - 17.1) and a posterior placenta (RR 6.8; 95% CI 2.8 - 16). Once turned, 97% of the babies remained cephalic until delivery. The caesarean section rate in each group was higher than the unit rate of 12.7%. There was one fetal death from cord prolapse in the vaginal breech delivery group.
外倒转术（ECV）在尼日利亚等发展中国家并非常见的手术。在3年的时间里，我们对尼日利亚一家大学教学医院接受外倒转术的女性进行了前瞻性研究。对成功进行外倒转术的组和未成功进行外倒转术的组进行了比较分析。在得到充分咨询后，尼日利亚女性愿意接受单胎足月臀位的外倒转术。外倒转术的成功率为67%。成功的有利因素包括经产妇（相对危险度，RR 3.8；95%可信区间，CI 1.14 - 12.1）、臀位屈曲（RR 2.4；95%CI 1.02 - 5.7）、臀位未衔接（RR 4.8；95%CI 1.3 - 17.2）、羊水量正常（RR 4.8；�5%CI 1.3 - 17.1）和胎盘后置（RR 6.8；95%CI 2.8 - 16）。一旦胎位转正，97%的婴儿直至分娩时仍为头位。每组的剖宫产率均高于该科室12.7%的平均水平。阴道臀位分娩组有1例因脐带脱垂导致的胎儿死亡。
