Which maneuver is used during a breech delivery to maintain the head's flexion?

The Mauriceau-Smellie-Veit maneuver is the correct choice for maintaining the head's flexion during a breech delivery. This maneuver involves the support of the fetal body while applying gentle traction to the legs and utilizing a specific technique to help guide the head out in such a way that it remains flexed.

This is particularly important in breech deliveries, as a flexed head can help prevent various complications such as cord prolapse or head entrapment. By using this maneuver, the provider can facilitate a safer delivery process while also decreasing the risk of trauma to both the fetus and the mother.

The other options focus on different situations in labor and delivery. For example, the McRoberts maneuver is primarily used for shoulder dystocia, where the legs are flexed and brought back towards the abdomen to help relieve impacted shoulders. Fundal pressure may be applied during certain stages of labor, but it is not specifically indicated for managing breech deliveries. Spinal manipulation is not a recognized procedure for maneuvering infants during delivery and does not apply in this context. Each of these methods is valuable in obstetric practice, but only the Mauriceau-Smellie-Veit maneuver directly addresses the need for maintaining flexion of the head during a
