How does McRoberts maneuver help with shoulder dystocia?

How does McRoberts maneuver help with shoulder dystocia?

The McRoberts maneuver does not change the actual dimensions of the maternal pelvis. Rather, it relieves shoulder dystocia via marked cephalad rotation of the symphysis pubis and by flattening the sacrum. The use of the McRoberts maneuver alone has been found to alleviate 39% to 42% of shoulder dystocias.

What does McRoberts maneuver do?

The McRoberts maneuver is an obstetrical maneuver used to assist in childbirth. It is named after William A. McRoberts, Jr. It is employed in case of shoulder dystocia during childbirth and involves hyperflexing the mother’s legs tightly to her abdomen.

How successful is McRoberts maneuver?

McRoberts’ and suprapubic pressure are often recommended as the initial choices of manoeuvres to manage shoulder dystocia, as they are believed to be less invasive compared to other manoeuvres. However, their success rates range from 23 to 40 %.

How do you diagnose shoulder dystocia?

Signs and symptoms. One characteristic of a minority of shoulder dystocia deliveries is the turtle sign, which involves the appearance and retraction of the baby’s head (analogous to a turtle withdrawing into its shell), and a red, puffy face. This occurs when the baby’s shoulder is obstructed by the maternal pelvis.

McRoberts manoeuvre – hyperflex maternal hips (knees to chest position) and tell the patient to stop pushing. This widens the pelvic outlet by flattening the sacral promontory and increasing the lumbosacral angle.

How often will the combination of McRoberts and suprapubic pressure?

However, even well conducted McRoberts’ manoeuvre and suprapubic pressure do not guarantee success of delivery without injury. Studies from previous cohorts have claimed success rates ranging from 23.2 to 58 % for McRoberts’ manoeuvre alone or in combination with suprapubic pressure [5, 13, 15].

Who can perform McRoberts maneuver?

The McRobert’s maneuver is performed by two people simultaneously. Two stools should be available on either side of the patient’s bed for the labor room personnel. An assistant may also help aid in the performance of suprapubic pressure if performed along with McRobert’s maneuver.

How long does it usually take for a shoulder dystocia to cause significant fetal hypoxia?

Considered an obstetric emergency, shoulder dystocia can result in significant fetal and maternal harm if not resolved in a competent and expedient manner. Cord pH drops with increasing head-to-body delivery interval, but the drop does not become clinically significant for about 5 minutes.

Is shoulder dystocia fatal?

Sadly, there is a risk that lack of oxygen during birth can lead to brain damage or even death. Sometimes shoulder dystocia can lead to complications for the mother, including tears, a haemorrhage, infection, or damage to the nerves causing incontinence.
