BACKGROUND: Nausea, vomiting, and pain frequently occur after thyoidectomy. Little evidence exists regarding the effects of administrating a combination of dexamethasone and tropisetron to patients undergoing thyroidectomy. We aimed to evaluate the effects of dexamethasone and tropisetron on thyroidectomy outcomes. METHODS: A total of 150 patients undergoing thyroidectomy were included in this prospective randomized, controlled, three-arm study (group D: 8 mg dexamethasone; group T: 5 mg tropisetron; group D+T: 8 mg dexamethasone and 5 mg tropisetron). There were 50 patients in each group. Nausea, vomiting, pain, and the amount of antiemetic and analgesic agents required were recorded 2, 4, 8, 16, 24, 36, and 48 h postoperatively. RESULTS: The complete response rate of nausea and vomiting was significantly higher in group D+T (78%, 39/50), compared with that in group D (58%, 29/50) or group T (66%, 33/50) (P = 0.01). The incidence and severity of nausea in group D+T were significantly lower than in group D and group T, with the difference mainly occurring in the late postoperative period (6-48 h). The severity of postoperative pain was significantly less in the dexamethasone-containing groups (D and D+T groups) than in the tropisetron group. CONCLUSIONS: The combination of dexamethasone and tropisetron offers better prophylaxis for nausea, vomiting, and pain than either drug alone in patients undergoing thyroidectomy, especially during the late period (6-48 h).
