Randomized Controlled Trial
[The effect of oral ondansetron in the prevention of postoperative nausea and vomiting].
Not so many years ago, the incidence of postoperative nausea and vomiting used to reach 40% to 50%. More recent publications indicate that this complication still reaches considerable frequency: 20 to 30%. The present study had the objective of evaluating the impact of oral administration of ondansetron on the incidence of postoperative nausea and vomiting among patients submitted to general anesthesia. ⋯ Ondansetron, 16 mg orally, administered before the operation significantly reduced the incidence of postoperative nausea and vomiting. The simplicity of administration and low cost of this presentation justify the choice of this administration route.
