Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Emergence time | From end of surgery to extubation (assessed up to 30 minutes after surgery) | When consciousness and self respiration are fully recovered after surgery is ended, extubation is tried. The time to extubation (emergence time) is recorded. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to spontaneous movement | From end of surgery to spontaneous movement (assessed up to 30 minutes after surgery) | After surgery is stopped, the patients are asked to open their eyes every 1 minute after the termination of sevoflurane administration. The time to spontaneous movement is recorded. |
| Time to eye opening | From end of surgery to eye opening (assessed up to 30 minutes after surgery) | After surgery is stopped, the patients are asked to open their eyes every 1 minute after the termination of sevoflurane administration. The time to eye opening is recorded. |
