Airway Management with Cervical Spine Immobilisation: A Comparison between the Macintosh Laryngoscope, Truview Evo2, and Totaltrack VLM Used by Novices—A Manikin Study

الملخص EN

Airway management in patients with suspected cervical spine injury plays an important role in the pathway of care of trauma patients.

The aim of this study was to evaluate three different airway devices during intubation of a patient with reduced cervical spine mobility.

Forty students of the third year of emergency medicine studies participated in the study (F=26, M=14).

The time required to obtain a view of the entry to the larynx and successful ventilation time were recorded.

Cormack-Lehane laryngoscopic view and damage to the incisors were also assessed.

All three airway devices were used by each student (a novice) and they were randomly chosen.

The mean time required to obtain the entry-to-the-larynx view was the shortest for the Macintosh laryngoscope 13.4 s (±2.14).

Truview Evo2 had the shortest successful ventilation time 35.7 s (±9.27).

The best view of the entry to the larynx was obtained by the Totaltrack VLM device.

The Truview Evo2 and Totaltrack VLM may be an alternative to the classic Macintosh laryngoscope for intubation of trauma patients with suspected injury to the cervical spine.

The use of new devices enables achieving better laryngoscopic view as well as minimising incisor damage during intubation.
