Cervical Spine Motion During Tracheal Intubation: Video Laryngoscope vs Rigid Video Stylet

A Randomized Comparison of Cervical Spine Motion During Tracheal Intubation Using Video Laryngoscope or Rigid Video Stylet in Patients With Simulated Cervical Immobilization

In this study, investigators are going to compare cervical spine motion during tracheal intubation using video laryngoscope or rigid video stylet in patients with simulated cervical immobilization.

In patients with an unstable cervical spine, neck extension during tracheal intubation may result in harmful events such as spinal cord injury. Thus, it is important to minimize cervical spine motion in these patients. In this randomized crossover study, investigators are going to compare cervical spine motion during tracheal intubation using video laryngoscope or rigid video stylet in patients with simulated cervical immobilization.
