Effect of transcutaneous electrical acupoint stimulation on postoperative gastrointestinal function in patients undergoing laparoscopic non-gastrointestinal surgery / 中华麻醉学杂志

ABSTRACT

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative gastrointestinal function in patients undergoing laparoscopic non-gastrointestinal hand surgery.Methods:Two hundred and sixty-seven patients, regardless of gender, aged 18-64 yr, of American Society of Anesthesiology physical status Ⅰ-Ⅲ, scheduled for elective laparoscopic cholecystectomy, laparoscopic bile duct exploration, and laparoscopic ovarian lesion resection under general anesthesia, were divided into 2 groups using a random number table method: control group (C group, n=147) and TEAS group ( n=120). From 30 min before induction of anesthesia to the end of operation, transcutaneous electrical stimulation of bilateral Zusanli and Hegu acupoints was performed at 30 min before induction of general anesthesia and maintained until the end of surgery with disperse-dense waves at frequency of 15-20 Hz and the maximum tolerated intensity.Combined intravenous-inhalational anesthesia was used in both groups.The time to first flatus and defecation was recorded.The occurrence of nausea and vomiting and abdominal distension within 24 h after surgery were recorded.The quantitative score of traditional Chinese medicine symptom of gastrointestinal function and Hamilton Anxiety Scale score were performed after surgery.The plasma motilin and gastrin levels were measured by enzyme-linked immunosorbent assay at 30 min before operation and 12 h after operation. Results:Compared with group C, the time to first flatus and defecation was significantly shortened, the incidence of postoperative nausea and vomiting and abdominal distension was decreased, the quantitative score of the traditional Chinese medicine and Hamilton Anxiety Scale score were decreased after operation, and the plasma motilin and gastrin levels were increased at 12 h after surgery in group TEAS ( P<0.05). Conclusion:TEAS can promote the recovery of gastrointestinal function after laparoscopic non-gastrointestinal surgery in the patients.
