Further study details as provided by Tehran University of Medical Sciences:

Primary Outcome Measures:
  • Time required for intubation in seconds [ Time Frame: From start of the intubation attempt for an average of one minutes ] [ Designated as safety issue: No ]
    The interval is measured from the time that the healthcare provider attempts intubation until a successful intubation is achieved.

Secondary Outcome Measures:
  • physicians' perception of the difficulty of the procedure [ Time Frame: Within an average of 30 minutes after completion of the procedure ] [ Designated as safety issue: No ]
    Physicians' perception about the difficulty of the procedure is assessed using a 5-point Likert type scale (ranging from very easy to very difficult)verbally administered to the healthcare provider immediately (within 30 minutes) after completion of the intubation

  • Number of Participants with Adverse Events [ Time Frame: From the start of the procedure until 30 minutes after the procedure is completed ] [ Designated as safety issue: Yes ]
    Number of patients developing any of the following complications (cough, esophageal intubation) from the start of the procedure until 30 minutes after completion of the procedure. This will represent the rate of complications

Estimated Enrollment: 70
Study Start Date: November 2012
Estimated Study Completion Date: February 2013
Estimated Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
