Capsicum plaster at the korean hand acupuncture point reduces postoperative nausea and vomiting after abdominal hysterectomy.

Abstract

Postoperative nausea and vomiting (PONV) are still common and distressing problems after general anesthesia, especially in patients undergoing abdominal hysterectomy. We studied a nonpharmacological therapy of PONV-capsicum plaster (PAS)-at either the Korean hand acupuncture point K-D2 or the Chinese acupuncture point Pericardium 6 (P6) of both hands. One-hundred-sixty healthy patients were included in a randomized, double-blinded study: 60 patients were in the control group, 50 patients were in the K-D2 group, and 50 patients were in the P6 group. PAS was applied at the K-D2 point in the K-D2 group and at the P6 point in the P6 group, whereas in the control group, an inactive tape was fixed at the K-D2 point of both hands. The PAS was applied before the induction of anesthesia and removed at 8 h after surgery. The incidence of PONV and the need for rescue medication were evaluated at predetermined time intervals. In the treatment group, the incidence of vomiting was significantly less (22% for the K-D2 group and 26% for the P6 group) than in the control group (56.7%) at 24 h after surgery (P < 0.001). The need for rescue antiemetics was significantly less in the treatment groups compared with the control group (P < 0.001). We conclude that PAS at the Korean hand acupuncture point K-D2 was an effective method for reducing PONV, as was PAS at the P6 acupoint, after abdominal hysterectomy. Capsicum plaster at either the Korean hand acupuncture point K-D2 or the Pericardium 6 acupoint reduces postoperative nausea and vomiting in patients undergoing abdominal hysterectomy.
