A prospective randomized controlled trial of external cephalic version (ECV) in late pregnancy is reported. All pregnancies were assessed with ultrasound and cardiotocography. ECV was successful in 29 out of 30 patients (97%). Breech presentation at delivery occurred in 67% of the control group and in 3% of the ECV group. The caesarean section rates were 43 and 20% respectively. Tocolysis was used in seven patients. A new technique of ECV with the steep lateral position is described. Complications were limited to cardiotocographic changes and one patient with unexplained vaginal spotting. The procedure is recommended provided appropriate patient selection and surveillance is practised.
