About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients who are scheduled transurethral resection of bladder tumor under general anesthesia
  • Patients aged between 20 and 79 years old
  • American Society of Anesthesiologists physical status ≤2
  • Patients who are voluntarily agreed to this clinical study

Exclusion criteria

  • A long operation (2 hours or longer)
  • Hearing disturbance
  • Cognitive disorder
  • Psychiatric substance abuse
  • Patient's denial

Treatment and study plan

Fresh gas flow of 5 L/min

Procedure

A fresh gas flow of 5 L/min is used during emergence from general anesthesia.

Fresh gas flow of 10 L/min

Procedure

A fresh gas flow of 10 L/min is used during emergence from general anesthesia.

Primary outcomes

  1. Emergence time

    Time frame: 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 outcomes

  1. Time to spontaneous movement

    Time frame: 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.

  2. Time to eye opening

    Time frame: 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.
