From 1984 to 1987, 300 pregnant women with fetal representations underwent an attempt at external cephalic version (ECV) during the last trimester. A consecutive analysis of factors associated with successful version was performed during this period. the final version rate after one or more attempts was 58%, being lower in nulliparous (39%) than in parous women (80%). Multivariate analyses (logistic regression) identified only three significant variables out of 16 with independent power to explain successful version. the overall most important factor was parity ( p < 0.001), followed by fetal presentation ( p < 0.001) and amount of amniotic fluid ( p = 0.019).
