Corticosteroids are often given to children undergoing tonsillectomy to reduce postoperative nausea and vomiting; however, previous research has suggested that corticosteroids may increase the risk of hemorrhage during and after surgery. Researchers set to determine the effect of dexamethasone, a corticosteroid, on bleeding. They found that administration of the dexamethasone to children during a tonsillectomy was not associated with excessive, serious bleeding events following surgery compared to patients who received placebo.
