Trade-offs support individualized second-stage epidural decisions; extends RCT evidence on balancing analgesia with delivery outcomes.
Does continuing epidural bupivacaine beyond 8 cm cervical dilatation improve analgesia and influence the method of delivery in nulliparous women?
Continuing epidural bupivacaine during the second stage of labor provides superior analgesia but is associated with a longer second stage and a higher rate of instrumental vaginal delivery.
