Effect of Amnioinfusion on External Cephalic Version Successful Rate

The aim of the study is to evaluate the effect of transabdominal amnioinfusion before second external cephalic version after initial failure.Patient with a single foetus, at term, in breech presentation and after a first cephalic version are included. The randomisation determines whether the patient is included in the group with amnioinfusion before second cephalic version or with usual second cephalic version only; The efficacy\'s evaluation is based on rate of cephalic presentation at birth.Success rate of cephalic version with or without transabdominal amnioinfusion, rates of cesarian section in the two groups,maternal and fetal morbidity, time between second cephalic version and birth will be studied. Prospective interventional randomized sequential comparative multicentric study. A maximum of 240 patients will be included (120 in each group). As the study is sequential it will be over as soon as a significative difference is shown.
