Brief summary

To compare the cuff pressure in lateral position between barrel-shaped cuff and taper-shaped cuff

Detailed description

The position of endotracheal tubes depends on the position of the patients. The change of the tube's position is known to influence the pressure of tube's cuff. The shape of the cuff (barrel-shaped versus tapered-shaped) may affect the tube's migration degree because of the difference of the frictional force. The investigator try to compare the the cuff pressure after supine-to-lateral position change between barrel-shaped cuff and taper-shaped cuff.

Interventions

Design outcomes

Primary

Measure	Time frame	Description
The cuff pressure after supine-to-lateral position change	At 10 minutes after anesthetic induction	The cuff pressure will be measured after supine-to-lateral position change using the Manometer Portex®.

Secondary

Measure	Time frame	Description
The distance from the tube to the carina	At 10 minutes after anesthetic induction	The distance from the tube to the carina will be measured using bronchoscopy after supine-to-lateral position change.
Complications related to endotracheal tube	At 0, 2, and 24 hours postoperatively	Complications related to endotracheal tube (sore throat, hoarseness, dysphagia and cough) will be measured as 0:none, 1:mild, 2:moderate, 3:severe at 0, 2, and 24 hours postoperatively.
