Background: We conducted this prospective,randomized,double-blind,placebo-controlled study to evaluates the effects of transcutaneous electric acupoint stimulation(TEAS)on the quality of recovery(QoR)and postoperative analgesia after gynecological laparoscopic surgery.Methods: 74 American Society of Anesthesiologists physical status(ASA)Ⅰ or Ⅱ patients undergoing gynecological laparoscopic surgery were randomly allocated to TEAS or control groups.The primary outcome was the quality of recovery,which was assessed on the day before surgery and 24h after surgery using a 40-item questionnaire.Secondary outcomes included postoperative pain scores,the incidence of postoperative nausea and vomiting(PONV),duration of postanesthesia care unit(PACU)stay and patient's satisfaction.Results: The TEAS group had higher QoR scores than control group upon 24h after surgery(177 vs.165;P< 0.001).Compared with the control group,postoperative pain scores and the cumulative number of opioids administered was lower in the TEAS group patients(P=0.04).TEAS reduced the incidence of PONV and dizziness,as well as duration of PACU stay.Simultaneously,the patient's satisfaction scores were higher in the TEAS group(P =0.002).Conclusion: Preoperative TEAS enhances QoR,improves postoperative analgesia and patient's satisfaction,alleviates postoperative side effects and accelerates discharge after general anesthesia for gynecological laparoscopic surgery.
