Which technique should not be applied to resolve shoulder dystocia due to potential complications?

Uterine fundal pressure is not recommended for resolving shoulder dystocia due to the potential for serious complications. Applying pressure to the fundus can inadvertently increase the risk of fetopelvic injury and compromise the maternal-fetal unit. It can also cause the fetal shoulder to become more wedged against the maternal pelvis, worsening the situation rather than alleviating it. Other techniques, such as the McRoberts maneuver, suprapubic pressure, and posterior arm release, are generally considered safer and more effective in managing shoulder dystocia, as they are designed to alleviate the obstruction while minimizing potential harm to both the mother and the baby.
