Summary
This study aims to design a prospective, double-blind, randomized controlled trial to compare the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on postoperative visceral pain in patients undergoing major abdominal surgery. Participants will be randomly assigned to receive either taVNS or sham stimulation. The total consumption of opioids and other analgesics within 24 hours post-surgery in the AICU will be recorded, along with follow-up assessments of pain scores and quality of recovery scores (Qor-15) at 24 hours postoperatively.
