Brief Summary:

Hypothesis: Aprepitant plus ondansetron is more effective than ondansetron plus placebo for prevention of postoperative emesis in patients at moderate-to-high risk for PONV for up to 48 hours after surgery.

Specific Aim: To determine the incidence of PONV during the first 48 hours after surgery; in patients who have received aprepitant plus ondansetron versus ondansetron plus placebo for up to 48 hours after surgery.

Condition or disease Intervention/treatment Phase
Postoperative Nausea and Vomiting Drug: Aprepitant plus Ondansetron Drug: Ondansetron plus placebo Phase 4

Primary Outcome Measures :
  1. Number of Participants Having Post-operative Emesis and Nausea. [ Time Frame: 48 hours post surgery ]
    Postoperative emesis was measured as present or not present (nominal data) and analyzed with Chi-square; Comparison of nausea severity was performed in two ways. In those patients who exhibited nausea VRS>0, a worst nausea score for each patient was defined as the highest nausea score recorded over the 48 hours. Mann-Whitney rank sum test was used to compare worst nausea scores. Multivariate Analysis of Variance (MANOVA) was used to determine if the mean VRS (Verbal Rating Scale) score over time was significant between the two groups.
