Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: •Opioid consumption at 24 hours (mean cumulative opioid consumption) •Opioid consumption at 6 hours after extubation (mean cumulative opioid consumption) ;Secondary Objective: •Pain intensity (NRS, 0-10) in the surgical area at rest and coughing at 1, 3, 6, 24, 48 and 72 hours after extubation •Pain intensity (NRS 0-10) in the legs (left and right, respectively) at 24 and 48 hours •Patient satisfaction (NRS, 0-10) with pain management at 24 hours after extubation •Nausea and/or vomiting (PONV) on a 4 point Likert scale (none/mild/moderate/severe) at 6 and 24 hours •Time from arrival to readiness for discharge from PACU (hours and minutes). •Level of sedation at observation at the PACU (Ramsay Sedation Scale) at 1 hour after extubation •Any adverse events during observation at the PACU: oHypoventilation (respiratory rate < 10/minutes) oHypoxemia (peripheral oxygen saturation < 94%) •Given treatment accordin to patient and investigator (24h) •3 months follow-up: EQ-5D, opioid consumption and pain intensity ;Primary end point(s): Opioid consumption;Timepoint(s) of evaluation of this end point: At 6 and 24 hours after extubation | — |
