Objective To evaluate the efficacy of transcutaneous electrical acupoint stimulation（TEAS） wristband on postoperative nausea and vomiting（PONV） in ambulatory hysteroscopic surgery patients. Methods A total of 250 patients who underwent ambulatory hysteroscopic surgery at our hospital from May 2024 to August 2025 were randomly divided into an observation group and a control group. In the observation group， a TEAS wristband was applied 30 minutes before surgery to deliver continuous stimulation at the unilateral Nei-guan acupoint， and removed after 6 h. The control group wore an identical TEAS wristband but received no electrical stimulation. Follow-up assessments were performed in the post-anesthesia care unit （PACU）， and at 6， 24， and 48 h postoperatively. The incidence and severity of PONV， pain scores， time to first flatus， and TEAS-related adverse reactions were recorded in both groups. Results Compared with the control group， the total incidence of PONV within 48 h postoperatively was significantly lower in the observation group （32.77% vs. 51.24%， P < 0.01）. This beneficial effect was most prominent within the first 6 h postoperatively， during which both the incidence and severity of PONV in the observation group were significantly reduced compared with the control group （P < 0.01）. No significant differences in the incidence and severity of PONV were noted between the two groups after 6 h postoperatively （P > 0.05）. The incidence of vomiting in the observation group was significantly lower than that in the control group during the period from PACU discharge to 6 h postoperatively （P < 0.05）， while no significant intergroup differences were found in other time periods （P > 0.05）. The time to first flatus in the observation group was significantly shorter than that in the control group （P < 0.01）. There were no significant differences in NRS pain scores at various postoperative time points or the usage rate of rescue antiemetic medications between the two groups （P > 0.05）. No serious TEAS-related adverse events occurred during the study period. Conclusion TEAS wristbands can safely and effectively prevent PONV in patients undergoing ambulatory hysteroscopic surgery， shorten the time to first postoperative flatus， and promote rapid postoperative recovery. These findings support the favorable application prospects of TEAS wristbands in ambulatory surgical settings.
