Questions about Postoperative Nausea and Vomiting

Does TEAS at PC6 reduce postoperative nausea and vomiting within 24 hours after hepatectomy?

No, TEAS at PC6 during hepatectomy did not significantly reduce PONV within 24 hours in a 2024 multicenter trial, though it may reduce painkiller use.

Can transcutaneous electrical acupoint stimulation reduce the risk of postoperative nausea and vomiting?

Yes, transcutaneous electrical acupoint stimulation (TEAS) can reduce the risk of PONV after laparoscopic surgery, but evidence is mixed for other surgeries.
