GlideScope Groove Versus Macintosh Blade for Double-Lumen Endotracheal Tube Intubation

Not Applicable

Withdrawn

• Conditions: Intubation, Intratracheal
• Interventions: Device: GlideScope Groove

• Registration Number: NCT01488695
• Lead Sponsor: Lawson Health Research Institute

Brief Summary

A new GlideScope videolaryngoscope has been developed, which utilizes a track on the superior surface of the blade to guide the endotracheal tube, which is advanced in the track as opposed to "free-hand" along the inferior surface, where the camera is located. This new GlideScope can be used for double-lumen endotracheal tubes (DLT). The investigators hypothesize that this GlideScope will be easier to use than the Macintosh blade.
