Both Glide scope and Pentax laryngoscope are video laryngoscope that provide the better view with minimal cervical spine movement. This study wants to compare cervical spine movement during intubation when using these two devices. The C-spine motion will be recorded by using fluoroscopic video to measure the angular displacement of the vertebrae.

    after intubation

Estimated Enrollment: 200
Study Start Date: May 2010
