From: The Cochrane Collaboration
- Lee, A., Fan, L.T., 1996. Stimulation of the wrist acupuncture point P6 for preventing postoperative nausea and vomiting, in: Cochrane Database of Systematic Reviews. John Wiley & Sons, Ltd.
- 40 trials involving 4,858 participants
- The paper is a systematic review / meta analysis of all relevant trials.
- This means that the data from all similar trials has been grouped to form an overall outcome.
- Compared with sham treatment, P6 acupoint stimulation significantly reduced: nausea (29%); vomiting (30%), and the need for rescue antiemetics (31%).
- There was no clear difference in the effectiveness of P6 acupoint stimulation for adults and children; or for invasive and noninvasive acupoint stimulation.
- There was no evidence of difference between P6 acupoint stimulation and antiemetic drugs in the risk of nausea (18% reduced risk), vomiting (1% increased risk), or the need for rescue antiemetics (18% reduced risk).
- The side effects associated with P6 acupoint stimulation were minor.
- Yes (with confidence)
