Brief Summary

For thyroid surgery, the special body position (thyroid surgical position) to exposure the patient's neck should be needed. For intraoperative neuromonitoring (IONM) in thyroid surgery, the tube should be placed at a specific position. A video laryngoscope can have advantages in tracheal intubation on thyroid surgical position for thyroid surgery. The purpose of the study is to investigate the effect of McGrath video laryngoscope on the glottic view when tracheal intubation is performed at the thyroid surgical position.

Conditions

Thyroid Surgery

video laryngoscope at thyroid surgical position

EXPERIMENTAL

After induction of anesthesia and muscle relaxation, the patient will be positioned with a standard pillow to exposure neck for thyroid surgery (thyroid surgical position). Then, tracheal intubation will be performed with a McGrath video laryngoscope. During laryngoscopy with the McGrath video laryngoscope, the intubation practitioner will record the modified Cormack-Lehane grade and the percentage of glottic opening (POGO) score when it is assumed that a direct laryngoscope is used and when using the video laryngoscope, respectively. Next, the intubation practitioner will perform tracheal intubation with it.

Device: video laryngoscope at thyroid surgical position
