Which maneuver is commonly employed to manage shoulder dystocia?

The McRoberts maneuver is a well-established technique used in the management of shoulder dystocia. This maneuver involves flexing the mother's legs tightly to her abdomen, which increases the pelvic diameter and may help to dislodge the impacted shoulder from beneath the pubic symphysis. By altering the angle of the pelvis, the McRoberts maneuver facilitates delivery and often proves effective in alleviating the shoulder dystocia situation.

In contrast, other methods listed in the choices do not specifically address the immediate physical intervention needed during a shoulder dystocia event. Cord clamping is a post-delivery action that does not assist in managing the complication itself. Vaginal inspection is generally performed to assess the situation but does not provide an active solution to the dystocia. Amniotomy, or artificially rupturing the membranes, may be used in some labor situations but is not a recognized intervention for shoulder dystocia and could potentially complicate the scenario further. Thus, the specific intent and effectiveness of the McRoberts maneuver make it the primary and most appropriate response in the context of managing shoulder dystocia.
