Transcutaneous auricular vagus nerve stimulation for postoperative nausea and vomiting in gynecological laparoscopic surgery: a randomized controlled trial protocol.

PubMed / Ann Med · 2026-07-11 · By Li P, Fan L, Chen Q, et al. · Annals of medicine

This randomized controlled trial protocol investigates whether transcutaneous auricular vagus nerve stimulation (taVNS) can reduce postoperative nausea and vomiting (PONV) in patients undergoing gynecological laparoscopic surgery.
