Prevention of shoulder dystocia: A randomized controlled trial to evaluate an obstetric maneuver.

Objective: Shoulder dystocia is a major obstetric emergency defined as a failure of delivery of the fetal shoulder(s). This study evaluated whether an obstetric maneuver, the push back maneuver performed gently on the fetal head during delivery, could reduce the risk of shoulder dystocia.

Study Design: We performed a multicenter, randomized, single-blind trial to compare the push back maneuver with usual care in parturient women at term.

Is maternal posturing during labor efficient in preventing persistent occiput posterior position? A randomized controlled trial.

Objective: We sought to evaluate the efficacy of maternal posturing during labor on the prevention of persistent occiput posterior (OP) position.

Study Design: We conducted a randomized trial including 220 patients in labor with a single fetus in documented OP position. Main outcome was the proportion of anterior rotation from OP position.
