The curative effect observation of different frequency of TEAS combined with wristband pressing on Neiguan (PC 6) for nausea and vomiting after laparoscopic cholecystectomy / 中国针灸

ABSTRACT

OBJECTIVE@#To compare the effects of different frequency of transcutaneous electrical acupoint stimulation (TEAS) combined with wristband pressing on Neiguan (PC 6) for nausea and vomiting (PONV) after laparoscopic cholecystectomy, and optimize the TEAS frequency selection for treatment of PONV.@*METHODS@#Eighty patients undergoing laparoscopic cholecystectomy were randomly divided into a postoperative routine care group, a 2 Hz TEAS combined with wristband pressing group (2 Hz TEAS group), a 100 Hz TEAS combined with combined with wristband pressing group (100 Hz TEAS group) and a 2 Hz/100 Hz TEAS wristband pressing group (2 Hz/100 Hz TEAS group), 20 cases in each group (1 patient dropped off in the postoperative routine care group). All the four groups underwent laparoscopic cholecystectomy, and routine nursing was given after the operation. In the postoperative routine nursing group，only routine nursing was received. In the other three groups, 2 Hz TEAS combined with wristband pressing, 100 Hz TEAS combined with wristband pressing, 2 Hz/100 Hz TEAS combined with wristband pressing to simulate Neiguan (PC 6) were treated on the basis of postoperative routine care after surgery. The treatment was given for 30 min each time for a total of 4 treatments. The incidence of PONV in each group was observed at 0-2 h, 2-8 h, 8-24 h and 24-48 h after operation, and the severity of PONV and postoperative pain were evaluated.@*RESULTS@#Compared with the postoperative routine care group, the incidence and severity of PONV in the four time periods after surgery were significantly reduced in the 2 Hz/100 Hz TEAS group (all <0.05), the incidence and severity of PONV in patients at 2 h and 2-8 h after surgery were significantly reduced in the 2Hz TEAS group and the 100 Hz TEAS group (all <0.05), the postoperative pain at 8 h and 24 h after surgery was alleviated in the 100 Hz TEAS group and the 2 Hz/100 Hz TEAS group (all <0.05).@*CONCLUSION@#Different frequency of TEAS combined with wristband pressing to stimulating Neiguan (PC 6) have certain therapeutic effects on PONV in patients undergoing laparoscopic cholecystectomy. 2 Hz/100 Hz TEAS combined with wristband pressing at Neiguan (PC 6) is more effective in PONV. 2 Hz/100 Hz TEAS and 100 Hz TEAS combined with wristband pressing at Neiguan (PC 6) have postoperative analgesic effect, and 2 Hz/100 Hz TEAS has the better analgesic effect.
