Question

All of the following maneuvers are used in shoulder dystocia, except:

• A. Woods corkscrew maneuver
• B. McRoberts maneuver
• C. Suprapubic pressure
• D. Mauriceau-Smellie-Veit maneuver

Hint:

Which listed maneuver actually belongs to vaginal breech delivery of the after-coming head?

Answer 1

The Correct Option is D

Step 1: Shoulder dystocia is an obstetric emergency where, after the head delivers, the anterior shoulder gets stuck behind the pubic symphysis and routine traction fails to deliver the baby. The aim of every maneuver is to disimpact that anterior shoulder.
Step 2: McRoberts maneuver (hyperflexion of the maternal thighs onto the abdomen) flattens the sacral promontory and rotates the symphysis upward, freeing the shoulder. It is the first-line step.
Step 3: Suprapubic pressure pushes the impacted anterior shoulder away from the midline so it slips under the symphysis. It is used along with McRoberts.
Step 4: Woods corkscrew maneuver rotates the posterior shoulder by 180 degrees to bring it under the symphysis and free the impaction. It is a recognised internal rotation maneuver.
Step 5: The Mauriceau-Smellie-Veit maneuver is used to deliver the AFTER-COMING HEAD in a breech (vaginal breech delivery), not for shoulder dystocia. So it is the exception here.
Hence the answer is Option D (Mauriceau-Smellie-Veit maneuver).
