Primary
| Measure | Time frame | Description |
|---|---|---|
| The primary endpoint was the composite measure complete response | 24 hours after the end of surgery | defined as no episodes of emesis (vomiting or retching) and no use of rescue medication in the first 24h after wound closure |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of no Nausea | 24 hours after end of surgery | Count of patients experiencing an episode of no nausea scored \< 1 of 0-10 verbal response scale during the 24 hours period after the completion of surgery |
| Incidence of moderate and severe Nausea | 24 hours after end of surgery | Count of participants with nausea score \> 4 on 0-10 verbal response scale |
| Incidence of Emesis (Vomiting/Retching) | 24 hours after end of surgery | An assessment of a participant experiencing an episode of emesis (vomiting/ retching) during the 24hours after the completion of the surgery |
| Use of Rescue Medication | 24 hours after end of surgery | — |
| Time to First Violation of Criteria for PONV | 24 hours after end of surgery | Criteria for PONV are any episode of emesis or use of rescue medication in the 24 hours after the end of surgery |
