Endotracheal Intubation Comparing Airtraq and McCoy Laryngoscope in Patients with Simulated Cervical Spine Immobilization.

Objectives: Sniffing position for laryngoscopy requires flexion of the lower and extension of upper cervical spine and atlanto-occipital joint. Laryngoscopy is challenging in cervical spine pathology. This study was conducted to compare Airtraq with McCoy for ease of intubation in patients with simulated cervical immobilization.
