Which technique may be used if initial maneuvers for shoulder dystocia are unsuccessful?

The Woods corkscrew maneuver is a technique used in cases of shoulder dystocia when initial maneuvers have not resolved the situation. This approach involves rotating the fetal shoulder to relieve the obstruction. Specifically, it involves applying pressure to the back of the shoulder in a rotational maneuver, which can help create space for the anterior shoulder to slip underneath the pubic symphysis.

This technique is particularly valuable in cases where the shoulders become impacted after the head is delivered, as it can effectively change the position of the shoulder that is stuck. By using the Woods corkscrew maneuver, healthcare providers aim to decrease the risk of trauma to both the mother and the infant during a critical time of labor, demonstrating its importance in the management of shoulder dystocia emergencies.

The other techniques mentioned serve different purposes in managing shoulder dystocia or are not focused on resolving a stuck shoulder situation.
