Drugs are only partially effective in preventing PONV and may cause adverse effects.
Alternative methods, such as stimulating an Acupuncture point on the wrist (P6 acupoint stimulation), have been studied in many trials.
The use of P6 acupoint stimulation can reduce the risk of nausea and vomiting after surgery, with minimal side effects. The risks of postoperative nausea and vomiting were similar after P6 acupoint stimulation and antiemetic drugs.
