Transcutaneous Electrical Acupoint Stimulation Accelerates the Recovery of Gastrointestinal Function after Cesarean Section: A Randomized Controlled Trial

Background. Gastrointestinal functional recovery is an important factor affecting postoperative outcome. The aim of this study was to evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on gastrointestinal function in women undergoing cesarean section. Methods. 150 pregnant women undergoing cesarean section were randomly allocated into TEAS, nonacupoint stimulation (sham group), and no stimulation (control group). The primary outcome was indications of gastrointestinal functional recovery and the secondary outcomes included time to first mobilization, postoperative hospital stay, daily living activities at one week after surgery, postoperative side-effects, and serum levels of gastroenterological hormones. Results. The time to first flatus in TEAS group was significantly shorter compared to control (P=0.004) and sham groups (P=0.003). The time to first oral liquid and solid intake was significantly shorter than that in control (P
