Bionic Balloon-assisted Delivery Technology on the Labor Process

Brief Summary

This multicenter, prospective, randomized controlled trial will evaluate the efficacy and safety of bionic balloon-assisted delivery technology in nulliparous women planning vaginal delivery. Eligible participants will be randomly assigned in a 1:1 ratio to either the intervention group or the control group. Participants in the control group will receive routine labor management, while participants in the intervention group will receive bionic balloon-assisted delivery in addition to routine labor management after entering the active phase of labor. The primary outcome is the duration of labor, including the first, second, and third stages of labor. Secondary outcomes include intrapartum cesarean conversion rate, intrapartum and postpartum complications, neonatal outcomes, postpartum pelvic floor dysfunction, postpartum depression, and maternal satisfaction. This study aims to determine whether bionic balloon-assisted delivery can shorten labor duration, reduce intrapartum cesarean conversion, and improve maternal and neonatal outcomes without increasing adverse events.
