OBJECTIVE: To verify the efficacy of dexamethasone in the prophylaxis of nausea and vomiting Laparoscopic cholecystectomy in patients submitted to laparoscopic cholecystectomy. Cholelithiasis METHODS: This was a systematic review of the literature through the MEDLINE, Embase, and Dexamethasone LILACS databases. Only controlled and randomized clinical trials comparing dexamethasone Postoperative nausea and vomiting to placebo in the prophylaxis of nausea and vomiting in patients submitted to laparoscopic cholecystectomy were included. RESULTS: The results of this review were based on data from 12 controlled and randomized clinical trials, totaling 947 patients. The group of patients who received preoperative dexamethasone showed lower incidence of nausea (number needed to treat [NNT] = 7), vomiting (NNT = 7), and need for smaller doses of rescue antiemetics (NNT = 6). CONCLUSION: The preoperative infusion of 8 mg of dexamethasone decreases the risk of complications in the postoperative period for patients submitted to laparoscopic cholecystectomy.
