STUDY OBJECTIVE: To determine the efficacy of transdermal scopolamine in addition to ondansetron in decreasing the incidence of postoperative nausea and vomiting (PONV). DESIGN: Randomized controlled trial. SETTING: Academic hospital. PATIENTS: 126 ASA physical status I and II patients undergoing outpatient plastic surgery with three or more risk factors for PONV. INTERVENTIONS: Patients were randomly assigned to one of two groups to receive (Group 1) a transdermal scopolamine (TDS) patch or (Group 2), a placebo patch two hours before surgery. MEASUREMENTS: Occurrence of vomiting, severity of nausea using a visual analog scale (VAS), rescue medication, pain intensity and pain medications, and side effects were recorded every hour until discharge from hospital, then every 4 hours thereafter for a total of 24 hours. MAIN RESULTS: A statistically significant reduction in postoperative nausea between 8 and 24 hours in patients receiving TDS was noted. CONCLUSIONS: Transdermal scopolamine in addition to ondansetron benefits patients at high risk for PONV undergoing outpatient plastic surgery for up to 20 hours after surgery.
