Dexamethasone has additive effect when combined with ondansetron and droperidol for treatment of established <scp>PONV</scp>

Abstract

Treatment of established PONV comprising ondansetron and droperidol, with or without dexamethasone, reduced PONV in both treatment groups. In those reporting PONV without active prophylaxis, the addition of dexamethasone resulted in a significant amplification of the PONV-reducing [corrected] effects of ondansetron and droperidol.
