Abstract: BAckground: Acupuncture and acupressure have previously been reported to possess antiemetic effect. We wanted to investigate the "true" and placebo effect of acupressure in prevention of postoperative nausea and vomiting (PONV). Patients and Methods: Sixty women undergoing outpatient minor gynaecological surgery were enterd into a double-blind and randomised study. One group received acupressure with bilateral stimulation of Per-6 (A), a second group received bilateral placebo stimulation (P) and a third group received n oacupressure wrist bandand served as areference group (R). PONV was evaluated as number of patients with complete response (no PONV), nausea or vomiting. In addition, the need forrescue antiemetic medication and nausea after 24 hours was registered. Results: COmplete response was obtained in 11, 11 and 9 patients in groups A, P and R, respectively. Nine, 7 and 6 patients had nausea before discharge home and 1,1 and 8 patients were nauseated (8 vs 1 patient: P < 0.05) 24 h after operation in A,P and R groups, respectively. When compared to placebo acupressure (2 patients vomited and 5 needed rescue), significant (P<0.05) fewer needed rescue etiemetic medica    tion afte acupressure at Per-6 (no vomiting or rescue medication). When compared to the observation group (5 vomited and 4 needed rescue antiemetics), significantly fewer vomited after acupressure (P < 0.05). COnclusion: In patients undergoing brief gynaecological surgery, placebo effect of acupressure decreased nausea after 24 h but vomiting and need of rescue antiemetics was educed only by acupressure with the correct Per-6 point stimulation
