Primary Outcome Measures
NameTimeMethod
Number of Participants With Complete Response24 hours after the end of surgery

The primary efficacy analysis was a comparison of the incidence of Complete Response, defined as no emesis (vomiting or retching) and no use of rescue medication in the 24 hours after the end of surgery, between the active group and the placebo group using Pearson χ2 test with Yates's continuity correction, and with a two-sided significance level of 5%.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With "Total Response"24 hours after the end of surgery

Total response is defined as no occurrence of vomiting/retching, no nausea score ≥ 1 and no use of rescue medication.

Number of Participants With no Nausea.24 hours after end of surgery

Nausea (defined as the desire to vomit without the presence of expulsive muscular movements) measured on a 0-10 verbal response scale, where 0=no nausea at all and 10=the worst nausea imaginable. "No nausea" means no score ≥ 1.

Number of Participants With no Emesis24 hours after end of surgery

Emesis is defined as vomiting (production of even the smallest amount of stomach contents) or retching (muscular movements of vomiting but without expulsion of stomach contents, usually because of an empty stomach)

Number of Participants With no Use of Rescue Medication24 hours after end of surgery

Any agent given in the post-operative period with the intention of providing anti-emetic rescue was counted as rescue anti-emetic medication for the purposes of efficacy determination, even if it did not achieve control of emesis or was given incorrectly (e.g., wrong dosage or route). Any agent given in the post-operative period which would be expected, by virtue of its pharmacology, dosage and route, to exert a clinically meaningful anti-emetic effect was considered as rescue anti-emetic medication, even if administered inadvertently or without the intention of providing rescue.

The Number of Participants With no Emesis, no Significant Nausea and no Use of Rescue Medication24 hours after the end of surgery

No occurrence of vomiting/retching, no nausea score ≥ 4 on verbal response scale (where 0=no nausea at all and 10=the worst nausea imaginable) and no use of rescue medication.

The Number of Participants With no Significant Nausea24 hours after the end of surgery

Nausea (defined as the desire to vomit without the presence of expulsive muscular movements) measured on a 0-10 verbal response scale, where 0=no nausea at all and 10=the worst nausea imaginable. "No significant nausea" means no score ≥ 4.
