BackgroundIn this randomized, single-blind, controlled study, we evaluated whether the 20 degrees reverse-Trendelenburg position had an effect on postoperative nausea and vomiting in patients undergoing thyroid surgery.MethodsPatients (n = 224) were given a standardized propofol anesthetic. Intraoperatively, patients were randomly assigned into two groups according to the tilt of the table maintained during surgery: patients were positioned with the neck extended and the table tilted with 20 degrees reverse-Trendelenburg or with the neck extended and the table positioned at a horizontal tilt. All episodes of postoperative nausea, vomiting, nausea severity score, frequency of vomiting, and the use of antiemetics were recorded during the first 24 h after anesthesia. We divided this time period into 0-3 h and 3-24 h.ResultsDuring the 0-3 h postoperative period, all observed episodes were comparable between groups. However, during the 3-24 h and the overall postoperative period, the incidence of nausea and/or vomiting, the nausea severity score, and frequency of vomiting were significantly less in the 20 degrees reverse-Trendelenburg position.ConclusionThe 20 degrees reverse-Trendelenburg position effectively ameliorates postoperative nausea and/or vomiting.
