简要总结
This randomized clinical study evaluated the effects of a lateral position with hip flexion and femoral internal rotation during the second stage of labor in nulliparous women receiving epidural labor analgesia. Participants were assigned to either an observation group using the modified lateral position or a control group using the conventional lateral position. The study compared second-stage labor duration, additional obstetric interventions, maternal outcomes, perineal outcomes, and neonatal outcomes between the two groups.
