External cephalic version (ECV): experience in a sub-Saharan African hospital.

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.
