Dexamethasone compared to metoclopramide in the prophylaxis of emesis in children undergoing ambulatory surgical procedures.

Background And Objectives: Postoperative vomiting is a common and unpleasant complication. Currently, however, mathematical models, such as number necessary to treat (NNT) and relative risk reduction (RRR), have been useful in the decision of which medication to use for prophylaxis. This study aimed at verifying whether dexamethasone, as compared to metoclopramide, decreases the incidence of vomiting when intravenously administered to children anesthetized with sevoflurane for ambulatory pediatric surgeries.
