biostudies-literatureUnknown27(1)Wu J<h4>Background</h4>Movement-evoked pain following pancreatectomy is often severe and inadequately controlled by conventional analgesic regimens. Transcutaneous electrical acupoint stimulation (TEAS), a non-invasive technique derived from acupuncture, has shown promise in reducing postoperative pain and opioid consumption. However, the efficacy of extended perioperative TEAS-particularly its sustained application through the early postoperative period-has not been evaluated in patients undergoing pancreatectomy.<h4>Methods</h4>This will be a prospective, single-center, two-arm, randomised controlled trial. A total of 132 patients undergoing pancreatectomy will be randomised allocated to the TEAS and the Sham TEAS groups. The TEAS group will receive stimulation (5-30mA, the stimulation intenTrials96https://www.ebi.ac.uk/biostudies/studies/S-EPMC12866311biostudies-literatureEfficacy of perioperative transcutaneous electrical acupoint stimulation on postoperative pain and recovery in patients undergoing pancreatectomy: a study protocol for a randomized controlled trial.PMC12866311Wu JZhou LChen JTang QfalseEfficacy of perioperative transcutaneous electrical acupoint stimulation on postoperative pain and recovery in patients undergoing pancreatectomy: a study protocol for a randomized controlled trial.<h4>Background</h4>Movement-evoked pain following pancreatectomy is often severe and inadequately controlled by conventional analgesic regimens.
