Airway Management Study to Evaluate the C-MAC Video Laryngoscope as an Alternative to the Direct Laryngoscopy

September 27, 2010 updated by: Johannes Gutenberg University Mainz

Evaluation of the C-MAC Video Laryngoscope After Failed Direct Laryngoscopy

The purpose of this study is to evaluate the C-MAC video laryngoscope in difficult airway situations.

Detailed Description

Unanticipated difficulties during tracheal intubation and failure to intubate are among the leading causes of anaesthesia related morbidity and mortality. Using the technique of video laryngoscopy, the alignment of the oral and pharyngeal axis to facilitate endotracheal intubation is obsolete. In this study we evaluate the C-MAC video laryngoscope (STORZ, Tuttlingen, Germany) for endotracheal intubation in difficult intubation situations (Cormack & Lehane (CL) grade 3 and 4) validated by Macintosh laryngoscope. We hypothesize that endotracheal intubation is possible using the C-MAC in patients after failed direct laryngoscopy. We also examine whether visualisation of the glottis is improved with this device compared to direct laryngoscopy and possible complications such as soft tissue injury.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: C-MAC
After a maximum of three failed intubation attempts using direct laryngoscope the C-MAC video laryngoscope is used as an emergency airway device.
Device: Endotracheal intubation using the C-MAC video laryngoscope
Using the C-MAC video laryngoscope for endotracheal intubation after failed direct laryngoscopy

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Success rate of endotracheal intubation using the C-MAC video laryngoscope
The investigators evaluate the C-MAC as an alternative after failed direct laryngoscopy. Primary outcome measure is the success rate using the C-MAC video laryngoscope in unexpected difficult airways.

Secondary Outcome Measures

Outcome Measure
Measure Description
- improved glottic view
According to the Cormacl-Lehane classification the improved glottis view using the C-MAC is documented.
- complications
Possible complications are supra glottic trauma, tooth damage, soft tissure bleeding,...
- numbers of intubation attempts
Necessary intubation attempts using the C-MAC video laryngoscope to secutre the airway.
- size of blade (C-MAC)
Different blades are available for the C-MAC. We evaluate with which blade securing the airway was possible.
