Acupressure treatment in postoperative nausea and vomiting prevention

Abstract

Background: Postoperative nausea and vomiting are common problems after general anesthesia, especially in ambulatory surgery. Drug therapy is often associated with side effects. We studied a non pharmacological method of therapy at the P6 point to prevent the side effects. Methods and Materials: Fifty-eight consecutive healthy patients undergoing a variety of short surgical procedures were included in a randomized, double-blind study in equal study and control groups. Patients in study group received injection of 3 ml normal saline into the P6 acupuncture point 30 minutes before the induction of anesthesia, while in control group injections performed inappropriately on the posterior surface. In both groups, the age, gender, height, weight, and type and duration of surgical procedures were all comparable without significant statistical difference. Results: In recovery room in study group, only 5 of 29 patients (17.2%) had nausea and vomiting as compared to control group, in which 15 of 29 patients (41.4%) had nausea and vomiting (P
