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

Johannes Gutenberg University Mainz50 enrolled

Overview

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

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technique of video laryngoscopy, the alignment of the oral and pharyngeal axis to facilitate endotracheal intubation is obsolete.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.

Outcomes

Primary Outcomes

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 Outcomes

- 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.
