Esketamine Combined With Transcutaneous Electrical Acupoint Stimulation on Postoperative Recovery Quality After Elective Cesarean Section

About This Study

This study is a prospective randomized controlled trial aimed at evaluating whether the combination of esketamine and transcutaneous electrical acupoint stimulation (TEAS) can improve the quality of postoperative recovery in women undergoing elective cesarean section. First-time mothers scheduled for surgery will be randomly assigned to one of four groups: a control group (standard care), a TEAS group, an esketamine group, or a combined group (TEAS plus esketamine). TEAS will be applied to specific acupoints before delivery. Esketamine (0.15 mg/kg) will be administered intravenously immediately after the umbilical cord is clamped to minimize fetal exposure. The primary outcome is the overall quality of recovery, assessed using the ObsQoR-11 scale during the first three days after surgery. We will also evaluate pain levels, sleep quality, anxiety and depression, early recovery milestones, inflammatory responses, adverse reactions, and newborn safety. The results may provide an effective multi-modal strategy to enhance recovery for mothers after a cesarean delivery.
