E-T Tube Cuff Pressure Change After Changing Position From Neutral to Hyperextension of Neck

Not Applicable

• Conditions: Thyroidectomy
• Interventions: Device: Mallinckrodt, COVIDIEN; Device: Endotracheal tube, Unomedica

• Registration Number: NCT02949856
• Lead Sponsor: Keimyung University Dongsan Medical Center

Brief Summary

This study evaluates difference of the endotracheal tube cuff pressure between a tapered- versus a cylindrical- shaped cuff after changing from neutral to hyperextension of neck.

Fifty patients undergoing thyroidectomy are randomly allocated into two groups (tapered- and cylindrical-shaped cuff). Endotracheal tube cuff pressure is initially set at 20 cmH20 in the supine neutral position and is measured after the change to the neck extension.
