A Randomized, Double-Blind Comparison of Oral Aprepitant Alone Versus Oral Aprepitant and Transdermal Scopolamine for Preventing Postoperative Nausea and Vomiting - Full Text View

Purpose

Recent evidence suggests multiple drug therapy is superior to single agents. The study compares the incidence of nausea, vomiting, need for rescue medication, prolonged PACU time, and unplanned hospital admission in patients with high risk for PONV treated with oral aprepitant with or without transdermal scopolamine preoperatively.

Primary Outcome Measures:

The outcomes measured include the incidences of nausea, vomiting, and their composite, as well as the need for rescue medication, and incidence of unplanned hospital admission; finally, the duration of PACU stay serves as an additional outcome variable. [ Time Frame: Arrival at PACU, and 10, 20, 30, 40, 50, and 60 minutes after arrival. ] [ Designated as safety issue: No ]

Estimated Enrollment:	120
