Study on the preventive effect of Neiguan acupoint stimulation combined with Zusanli acupoint stimulation on postoperative nausea and vomiting in patients undergoing hysteroscopic surgery

OBJECTIVE: To explore the preventive effect of thumbtack needle Neiguan acupoint stimulation combined with Zusanli acupoint stimulation on postoperative nausea and vomiting in patients undergoing hysteroscopic surgery. EXPERIMENTAL PROCEDURE: Using convenient sampling, 90 patients scheduled for hysteroscopic surgery were enrolled and randomly assigned to group A (Neiguan acupoint stimulation combined with Zusanli acupoint stimulation group), group B (Neiguan acupoint stimulation group), and group C (Streitberger sham acupuncture group). Postoperative nausea, vomiting and pain indicators were collected for comparison. RESULTS: The incidence of postoperative nausea in group A and group B was lower than that in group C at 0 ~ 6 h, and the incidence of postoperative vomiting in group A and group B was lower than that in group C at 0 ~ 6 h and 6 ~ 12 h. There were significant differences in VAS scores and postoperative exhaust time between the three groups at 6,12 and 24 h after operation. Further pairwise comparison showed that the VAS scores and postoperative exhaust time of group A at 6,12 and 24 h after operation were the smallest (P < 0.05). CONCLUSION: Combined acupoint stimulation at Zusanli and Neiguan was more effective in reducing the severity of nausea and vomiting and accelerating postoperative recovery than stimulation of Neiguan alone or sham control.
