Optimizing Management of the Second Stage of Labor: A Multicenter Randomized Controlled Trial.

To review the findings of the Optimizing Management of the Second Stage of Labor randomized controlled trial in the context of prior and subsequent obstetric literature. A multi-database search was performed in addition to a review of the parent trial and secondary studies. Nulliparous patients with neuraxial anesthesia randomized to either immediate or delayed pushing showed no difference in vaginal delivery rates. However, delayed pushing is associated with an increased duration of the second stage and perinatal morbidity. Patients should be appropriately counseled on the timing of second-stage pushing and the risks of prolonged second-stage labor.
