Arm && Interventions

Group	Intervention	Description
Group Five	Fresh gas flow of 5 L/min	For emergence from general anesthesia, a fresh gas flow of 5 L/min is used.
Group Ten	Fresh gas flow of 10 L/min	For emergence from general anesthesia, a fresh gas flow of 10 L/min is used.

Primary Outcome Measures

Name	Time	Method
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

Name	Time	Method
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.
