About

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

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technique of video laryngoscopy, the alignment of the oral and pharyngeal axis to facilitate endotracheal intubation is obsolete.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

Description:

After a maximum of three failed intubation attempts using direct laryngoscope the C-MAC video laryngoscope is used as an emergency airway device.
