History of Changes
  Purpose

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.

Intubation, Intratracheal
 Device: GlideScope Groove
Device: Control: Macintosh blade

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Double Blind (Subject, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Comparison of GlideScope Groove to Macintosh Blade for Orotracheal Intubation With Double-Lumen Endotracheal Tube: a Randomised Controlled Trial

Further study details as provided by Lawson Health Research Institute:

Primary Outcome Measures:
  • Duration of Intubation [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    The intubation will be timed using a stopwatch.


Secondary Outcome Measures:
  • Number of intubation attempts [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    Number of intubation attempts

  • Number of failures to intubate [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    Number of failures to intubate

  • Use of external laryngeal pressure [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    Whether or not external laryngeal pressure was needed to facilitate tracheal intubation

  • Laryngoscopic grade distribution [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    Cormack and Lehane Grade observed during laryngoscopy

  • Presence of Sore throat [ Time Frame: Day 3 ] [ Designated as safety issue: No ]
    Sore throat will be graded on POD #2 as none, mild, moderate, or severe
