STorz Against Glidescope Effectiveness

This study evaluates success rates of tracheal intubation (passing a breathing tube)for patients who may be more challenging to intubate while utilizing one of two devices that facilitate placement of the tube with video technology.

Treatment and study plan

C-MAC

Device

C-MAC arm

Glidescope

Device

Glidescope arm

Primary outcomes

  1. Intubation Success Rate

    Time frame: 1 week

    Success rate is defined as a single blade insertion with successful tracheal tube placement confirmed by return of end-tidal carbon dioxide

Secondary outcomes

  1. Intubation Time

    Time frame: 1 week

    Intubation time is defined as the time from blade insertion to first return of end-tidal carbon dioxide

  2. Graded Score of Laryngeal View Achieved

    Time frame: 1 week

    Laryngeal view is defined by the modified Cormack and Lehane scale (1-4) and is assessed by the clinician and the study team. Grade 1 is considered to be a good view while grade 4 is considered to be a poor view.

  3. Number of Particpants Requiring Adjuncts to Assist Intubation

    Time frame: 1 week

    The need for use of a gum-elastic bougie or external laryngeal manipulation to facilitate tube placement will be measured by the study team.

  4. Number of Participants With Observed Complications

    Time frame: 1 week

    Patients will be examined for evidence of mucosal or dental injury upon intervention. Patients will be asked if they have a sore throat in the recovery room, and their medical record will be reviewed to determine if any other airway related complications were observed by the clinical team including the need for reintubation or steroid administration to reduce swelling.
