  Purpose

The use of the video laryngoscope to teach laryngoscopy will improve the performance of tracheal intubation done by novices because it will allow a shared view of the airway leading to a better feedback from the trainer to the trainee.


Condition Intervention
Intubation Intraesophageal
Device: Airtraq
Other: Control group, taught with a standard Macintosh laryngoscope

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Official Title: A Clinical Trial on the Effectiveness of Video System in Improving Learning of Tracheal Intubation Using Standard Laryngoscopy Among Novices

Further study details as provided by Northwestern University:

Primary Outcome Measures:
  • Successful Endotracheal Intubation [ Time Frame: 120 seconds ] [ Designated as safety issue: No ]
    A successful placement of the endotracheal tube as defined by the presence of bilateral breath sounds and positive recording of end tidal carbon dioxide.


Secondary Outcome Measures:
  • Time to Intubation [ Time Frame: 120 seconds ] [ Designated as safety issue: No ]
    Time to intubation is the time interval of blade insertion until the removal of the laryngoscope.


Enrollment: 90
Study Start Date: February 2010
Study Completion Date: February 2011
Primary Completion Date: February 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
control group
Control group, taught with a standard Macintosh laryngoscope
Other: Control group, taught with a standard Macintosh laryngoscope
Subjects were taught how to use the Mackintosh blade first
Experimental: Study group
Study group taught with the Airtraq video laryngoscope
Device: Airtraq
Subjects were taught with the Airtraq video laryngoscope

Detailed Description:

A group of 30 fourth year medical students and interns rotating through the department of anesthesiology will be studied. Firstly, a standard lecture will be provided in which the description and importance of laryngoscopy and tracheal intubation will be explained. This will include descriptions of anatomy, relevant equipment and technique of tracheal intubation. Following the lecture , the students will be randomly allocated using sealed envelopes into two groups : a control group ( taught with a standard Macintosh Laryngoscope ) and a study group ( taught with the Airtraq video laryngoscope).Each group will receive a demonstration and verbal instruction on how to perform laryngoscopy and tracheal intubation by their instructor.
