Study Description
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.

Outcome Measures

Primary Outcome Measures :
  1. Duration of Intubation [ Time Frame: Day 1 ]
    The intubation will be timed using a stopwatch.


Secondary Outcome Measures :
  1. Number of intubation attempts [ Time Frame: Day 1 ]
    Number of intubation attempts

  2. Number of failures to intubate [ Time Frame: Day 1 ]
    Number of failures to intubate

  3. Use of external laryngeal pressure [ Time Frame: Day 1 ]
    Whether or not external laryngeal pressure was needed to facilitate tracheal intubation

  4. Laryngoscopic grade distribution [ Time Frame: Day 1 ]
    Cormack and Lehane Grade observed during laryngoscopy

  5. Presence of Sore throat [ Time Frame: Day 3 ]
    Sore throat will be graded on POD #2 as none, mild, moderate, or severe
