Acupuncture prevents postoperative nausea and vomiting.

There was a randomized controlled clinical trial for acupuncture stimulation of Neiguan (PC6) for preventing postoperative nausea and vomiting. There were 60 patients who were undergoing craniotomy. They were allocated into two groups: acupuncture group and control group. 30 pateints were in each group. Then regaining consciousness from the surgical anesthesia, patients in acupuncture group received acupuncture immediately and the acupuncture points used were bilateral PC6. The needles were manipulated about 1 min and repeated 10 min after insertion. The needles were left in the place for about 20 min after second manipulation. Patients in control group received no treatment.  Result showed that in acupuncture group one patient had a vomiting from 0-2 hours after acupuncture treatment; one patienthad a vomiting from 2-6 hours after the treatment; and no patients had vomiting 6 hours after the treatment. In contrast, in control group, 11 patients had vomiting from 0-2 hours; 8 patients had vomiting from 2-6 hours; and 8 patients had vomiting from 6-24 hours. The nausea scores were significantly lower in acupuncture group in all three time scale compared with control group. Their conclusion was that acupuncture at PC6 point was effective in preventing and treating postoperative nausea and vomiting in patients undergoing craniotomy.
