About this study

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technique of video laryngoscopy, the alignment of the oral and pharyngeal axis to facilitate endotracheal intubation is obsolete.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

Treatment and study plan

Endotracheal intubation using the C-MAC video laryngoscope

Device

Using the C-MAC video laryngoscope for endotracheal intubation after failed direct laryngoscopy

Primary outcomes

  1. 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

  1. - improved glottic view

    According to the Cormacl-Lehane classification the improved glottis view using the C-MAC is documented.

  2. - complications

    Possible complications are supra glottic trauma, tooth damage, soft tissure bleeding,...

  3. - numbers of intubation attempts

    Necessary intubation attempts using the C-MAC video laryngoscope to secutre the airway.

  4. - size of blade (C-MAC)

    Different blades are available for the C-MAC. We evaluate with which blade securing the airway was possible.
