Detailed Description
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.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Group Five For emergence from general anesthesia, a fresh gas flow of 5 L/min is used. |
Procedure: Fresh gas flow of 5 L/min
A fresh gas flow of 5 L/min is used during emergence from general anesthesia.
|
| Experimental: Group Ten For emergence from general anesthesia, a fresh gas flow of 10 L/min is used. |
Procedure: Fresh gas flow of 10 L/min
A fresh gas flow of 10 L/min is used during emergence from general anesthesia.

Outcome Measures
Primary Outcome Measures
- 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 Outcome Measures
- 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.
