Outcome Measures

Primary Outcomes (1)

  • Association between band power changes in EEG and hormone respones caused by endotracheal intubation

    from the start of anesthesia induction to one minute after endotracheal intubation

Secondary Outcomes (1)

  • Association between band power changes in EEG and hormone respones caused by surgical incision

    from the start of anesthesia induction to one minute after surgical incision

Interventions

Inserting endotracheal tube into the trachea
