Objective,2,To study the effect of transcutaneous electrical acupoint stimulation （TEAS） combined with palonosetron on postoperative nausea and vomiting （PONV） in patients after hysteroscopic surgery.,Methods,2,Eighty patients undergoing hysteroscopic surgery were selected and randomly divided into Palonosetron group （group A） and TEAS combined with Palonosetron group （group B）， 40 cases in each group. The occurrence of nausea and vomiting at 1 h， 6 h， 12 h and 24 h after surgery was recorded. The time of the first anal exhaust after operation and the patients’ satisfaction score at 24 h after surgery was evaluated.,Results,2,①Compared with group A， the incidence of PONV at 1 h and 6 h after operation in group B was significantly decreased （,P,<,0.05）. There was no significant difference in the incidence of PONV between the two groups at 12 h and 24 h after surgery （,P,>,0.05）. ②Compared with group A， the first anal exhaust time after operation was significantly shorter in group B （,P,<,0.05）. ③Compared with group A， postoperative satisfaction score of patients was significantly higher in group B （,P,<,0.05）.,Conclusion,2,TEAS combined with intravenous palonosetron can significantly reduce the incidence of nausea and vomiting in patients after hysteroscopic surgery， shorten the first anal exhaust time after surgery and improve patients’ satisfaction， which is beneficial to the quick recovery of patients after surgery.
