Introduction:

The McRoberts Maneuver is a technique used in obstetrics to alleviate shoulder dystocia during vaginal delivery. This comprehensive article aims to provide insights into the principles, indications, and procedure of the McRoberts Maneuver. Understanding this maneuver is crucial for healthcare professionals involved in obstetric care to safely and effectively manage shoulder dystocia and promote successful vaginal delivery.

Principles of the McRoberts Maneuver:

• Shoulder Dystocia: Shoulder dystocia occurs when the baby's shoulder becomes impacted behind the mother's pubic bone during delivery, leading to difficulty in delivering the fetal shoulders after the head has emerged.
• Maternal Pelvic Tilting: The McRoberts Maneuver involves hyperflexing the mother's legs onto her abdomen, which results in significant anterior rotation of the maternal pelvis, thereby increasing the pelvic outlet diameter.
• Reduction of Bony Obstruction: By increasing the pelvic outlet diameter, the McRoberts Maneuver reduces the bony obstruction and provides more space for the delivery of the fetal shoulders.

Indications and Procedure:

Indications: The McRoberts Maneuver is typically performed when shoulder dystocia is encountered during vaginal delivery, where the delivery of the fetal shoulders is impeded.

Procedure:

• With the mother in the lithotomy position, her legs are flexed sharply onto her abdomen.
• The healthcare provider applies gentle suprapubic pressure to assist in the anterior rotation of the maternal pelvis.
• The maneuver is maintained until the delivery of the anterior shoulder is achieved.
• Additional maneuvers may be required if the McRoberts Maneuver alone does not resolve the shoulder dystocia.

Benefits and Effectiveness:

• Increased Success Rate: The McRoberts Maneuver has been shown to be effective in resolving shoulder dystocia, leading to successful vaginal delivery.
• Non-Invasive Technique: The McRoberts Maneuver is a non-invasive maneuver that can be easily performed at the bedside without the need for additional instrumentation or anesthesia.
• Minimized Maternal and Neonatal Morbidity: By facilitating the vaginal delivery of the fetal shoulders, the McRoberts Maneuver helps reduce the risk of maternal and neonatal complications associated with prolonged or traumatic delivery.

Considerations and Additional Measures:

• Team Communication: Effective communication among the obstetric team is crucial during the management of shoulder dystocia, ensuring coordinated efforts and timely intervention.
• Maneuver Sequence: The McRoberts Maneuver is often employed as the initial maneuver in shoulder dystocia, followed by additional techniques such as suprapubic pressure, rotational maneuvers, or fetal manipulation if necessary.
• Maternal Comfort and Support: Ensuring the mother's comfort and emotional support during the maneuver is essential to alleviate anxiety and enhance cooperation.

Conclusion:

The McRoberts Maneuver is a valuable technique used in obstetric care to manage shoulder dystocia during vaginal delivery. Understanding the principles, indications, and procedure of the McRoberts Maneuver is crucial for healthcare professionals involved in obstetrics to promote successful vaginal delivery while minimizing maternal and neonatal morbidity associated with shoulder dystocia.
