Randomized Controlled Trial Comparative Study
Comparison of C-MAC® conventional blade, D-Blade™, and Macintosh laryngoscopes for endotracheal intubation in patients with simulated immobilization using manual in-line stabilization: A randomized trial.
A difficult airway is anticipated with cervical spine injuries (CSIs) as immobilization techniques such as manual in-line stabilization (MILS) are used, which distort the oro-pharyngeal-laryngeal axis. Video laryngoscopes (VLs) make difficult airway management easy, as they do not require axis alignment. The present study aimed to compare the total time taken by Macintosh laryngoscope (ML), conventional blade, and D-blade ™ of C-MAC ® VL in simulated CSI scenarios using MILS. ⋯ C-MAC ® VL requires less time for intubation, provides better glottic view, and has higher success, with better attenuation of hemodynamic response and fewer complications compared to ML.
