Study Description

Brief Summary:

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 or disease	Intervention/treatment	Phase
Intubation Intraesophageal	Device: Airtraq; Other: Control group, taught with a standard Macintosh laryngoscope	Not Applicable

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.

Arms and Interventions

Arm	Intervention/treatment
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

Outcome Measures

Primary Outcome Measures :

1. Successful Endotracheal Intubation [ Time Frame: 120 seconds ]
   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 :

1. Time to Intubation [ Time Frame: 120 seconds ]
   Time to intubation is the time interval of blade insertion until the removal of the laryngoscope.
