The purpose of this study is to evaluate the effect of fresh gas flow on emergence time in patients undergoing transurethral resection of bladder tumor.
The purpose of this study is to evaluate the effect of fresh gas flow (5 L/min vs. 10 L/min) on emergence time in patients undergoing transurethral resection of bladder tumor.

| Label | Type | Description | Intervention Names |
|---|---|---|---|

| Fresh gas flow of 5 L/min | Procedure | A fresh gas flow of 5 L/min is used during emergence from general anesthesia. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Emergence time | When consciousness and self respiration are fully recovered after surgery is ended, extubation is tried. The time to extubation (emergence time) is recorded. | From end of surgery to extubation (assessed up to 30 minutes after surgery) |
| Measure | Description | Time Frame |
|---|---|---|
| Time to spontaneous movement | 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. | From end of surgery to spontaneous movement (assessed up to 30 minutes after surgery) |
| Time to eye opening |
