Poujade O, et al. - A multicenter, randomized, single-blind trial was performed to assess whether an obstetric maneuver, the push back maneuver performed gently on the fetal head during delivery, could decrease the risk of shoulder dystocia. No significant between-group differences in neonatal complications, including brachial plexus injury, clavicle fracture, hematoma and generalized asphyxia was found. The push back maneuver significantly reduced the risk of shoulder dystocia, as compared with standard vaginal delivery in this trial in 945 women who delivered vaginally.
