Summary

Direct laryngoscope requires proper alignment of the oro-pharyngeal-laryngeal axis to provide an optimal glottic view for intubation. However, in cervical spine patients, this alignment is not possible thus resulting in an increased risk of fail intubations.

D-blade comes with an elliptically tapered blade shape rising at the distal end to provide better glottic visualization in comparison with direct laryngoscopes. Hence, CMAC D-blade is preferred in simulated cervical spine injury where intubator needs to maintain a neutral neck position. However, intubation time may be significantly longer due to difficulty in negotiating the endotracheal tube pass vocal cord and impingement of endotracheal tube to the anterior wall of trachea.

There is a study published Glidescope which is also a hyperangulated videolaryngoscope suggested that obtaining a partial glottic view of larynx may facilitate a faster and easier tracheal intubation when compare to a full glottis view. The aim of this study is to clinically evaluate the time of tracheal intubation in relation to the full glottic view vs. partial glottic view which is deliberately obtained when using CMAC D-blade video laryngoscopy in simulated cervical spine injury.
