Acupoint Injection and Electrical Stimulation for Postoperative Nausea and Vomiting: A Randomized Clinical Trial

To date, no study has investigated the efficacy of combining AI and TEAS for preventing PONV after gynecological laparoscopic surgery. We aimed to assess the effectiveness and safety of this integrated therapy, comparing the effects of only AI or TEAS program with a combined regimen, providing a more effective and low-risk alternative to pharmacological treatments.In this randomized trial, dexamethasone injection into the Neiguan acupoint effectively prevented PONV and reduced the need for salvage antiemetics when combined with TEAS.
