STorz Against Glidescope Effectiveness

Not Applicable

Completed

• Conditions: Difficult Airway
• Interventions: Device: Glidescope; Device: C-MAC

• Registration Number: NCT01632683
• Lead Sponsor: Oregon Health and Science University

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Glidescope	Glidescope	Providers will utilize the Glidescope video laryngoscope equipped with the #4 blade to facilitate intubation
C-MAC	C-MAC	Providers will utilize the C-MAC video laryngoscope equipped with a D-blade to facilitate intubation

Primary Outcome Measures

Name	Time	Method
Intubation Success Rate	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 Outcome Measures

Name	Time	Method
Graded Score of Laryngeal View Achieved	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.
Number of Participants With Observed Complications	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.
Intubation Time	1 week	Intubation time is defined as the time from blade insertion to first return of end-tidal carbon dioxide
Number of Particpants Requiring Adjuncts to Assist Intubation	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.
