For tracheal intubation with a lightwand, adequate bending angle was not exactly investigated. The purpose of the study is compare three bending angles of lightwands for safe and efficient tracheal intubation.
Lightwands are very useful device for difficult airway management due to small moth opening, weak teeth, and cervical spine instability. Experienced clinicians use a lightwand while bending it adequately. However, there has been not previous studies to investigate the adequate angle to bend it. This randomized controlled trial is to compare three angles (70, 80, and 90 degrees) as bending angle of lightwands for safe and efficient tracheal intubation in cases which require the use of lightwands.

For tracheal intubation, investigators will bend the tracheal tube combined a lightwand by assigned angles (70, 80, or 90 degrees) for each patient. Next a practitioner will perform tracheal intubation with the bent tube.

After surgery, investigators evaluate VAS score for sore throat of the patients.
Time frame: After surgery
Intubation time
from initiation of tracheal intubation with a lightwand after bending it to completion of tracheal intubation
Time frame: Intraoperative
