External cephalic version in breech presentation under tocolysis.

A prospective trial is presented of the benefits and risks of external cephalic version in breech presentation. From January through October 1977, attempts at external version were performed in 53 cases with a success rate of 70%. The version technique is described. Mode of delivery after the maneuver in mothers with breech presentation who for different reasons were not included in the series is reported as well. Both the incidence of breech presentation and the incidence of cesarean section in breech presentation were reduced during the period of study. No serious complications in association with attempts at external version were observed.
