Comparison of Adding EMEND to PONV/PDNV Treatment Regimen

This study is looking at whether the addition of Aprepitant (Emend), an antiemetic, will provide added efficacy if added to 2 drugs that are already used as a standard of care for post-operative nausea and vomiting and post-discharge nausea and vomiting.

This study is looking at whether the addition of a fairly new drug for the treatment of post-operative nausea and vomiting (PONV) and post-discharge nausea and vomiting (PDNV) will provide added efficacy if added to 2 drugs that are already used as a standard of care for PONV and PDNV. The patients that will be looked at will be deemed at higher risk for PONV and PDNV based on the procedure they are having done and/or on patient risk factors.
