Study Details

Study Description

Brief Summary

Previous study showed that McGrath Series 5 videolaryngoscope is an alternative tool for double-lumen tube intubation. We have compared it with traditional Macintosh laryngoscopefor double-lumen tube intubation. In this study, we will investigate its role in double-lumen tube intubation by comparison with another videolarygoscope.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: McGrath Series 5 DLT intubation with McGrath Series 5 videolaryngoscope	Device: McGrath Series 5; one kind of videolaryngoscopes, which are widely used in airway management.
Active Comparator: Airtraq DLT intubation with Airtraq videolaryngoscope	Device: Airtraq; another kind of videolaryngoscopes, which are also widely used in airway management.

Outcome Measures

Primary Outcome Measures

1. Intubation time [at intubation]

   defined as time from inserting blade to mouth to withdrawal of blade, measured with a stopwatch

Other Outcome Measures

1. Airway evaluation with Cormack-Lehane Score [At intubation]

   based on Cormack-Lehane classification. degree 1 to 4
