Our findings are in direct contrast with those of Dundee et al.2 A much larger study, of more than 200 subjects, would be required to rule out even a minor antiemetic effect of acupuncture (that is, a 10% difference between the groups). We chose, however, to limit our study to 46 subjects, as our results suggested that acupuncture at the P6 locus, in the way that we used it, is unlikely to be a clinically useful prophylactic for postoperative nausea and vomiting.
