Abstract: OBJECTIVE:To investigate the effect of transcuta neous electrical acupoint stimulation(TEAS)on en ha nced recovery after surgery(ERAS)in laparo scopic colorectal cancer resection and its clinica sig nificance.METHODS:Sixty-four patients undergoing laparoscopic colorectal resection were randomly divided into two groups,the control group(group A)and the TEAS group(group B).Patients in the TEAS group received electroacupuncture stimulation of bilateral Zusanli(ST 36)at 30 min before anesthesia to the end of surgery.The patients in the control group were not given the stimulation.Perioperative anesthesia management of the two groups were performed according to the ERAS guidelines,and postoperative patient-controlled intravenous analgesia(PCIA)was used.The amount of remifentanil used in the two groups was observed and recorded,and the visual analogue scale(VAS)of the 4,12,24 and 48 h after surgery in the two groups was recorded.Moreover,postoperative anal exhaust time,postoperative feeding time,postoperative first ambulation time and postoperative hospital stay length were compared between the two groups.RESULTS:Compared with group A,the VAS score of group B decreased significantly at 48 h after operation(P0.05).CONCLUSION:TEAS can promote the recovery of postoperative gastrointestinal function and reduce the pain intensity 48 h after surgery,thus satisfying the need of early postoperative analgesia.
