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.
Time frame: From end of surgery to extubation (assessed up to 30 minutes after surgery)
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.
Time frame: From end of surgery to spontaneous movement (assessed up to 30 minutes after surgery)
Time to eye opening
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.
Time frame: From end of surgery to eye opening (assessed up to 30 minutes after surgery)
