Condition c-spine movement during intubation
Treatments the glidescope video laryngoscopy, the pentax airwayscope
Sponsor Prince of Songkla University
Start date May 2010
End date June 2011
Trial size 200 participants
Trial identifier NCT01347151, Glide VS Pentax


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.
