The Effect of Timing of Dexamethasone Administration on Its Efficacy as a Prophylactic Antiemetic for Postoperative Nausea and Vomiting

Abstract

We evaluated the effect of timing of dexamethasone administration on its efficacy as a prophylactic antiemetic on postoperative nausea and vomiting. We found that dexamethasone, when given immediately before the induction of anesthesia, was more effective than when given at the end of anesthesia.
