A Comparison of Cervical Spine Movement During Tracheal Intubation Using the Pentax or the Glidescope

Not Applicable

• Conditions: C-spine Movement During Intubation
• Interventions: Device: The glidescope video laryngoscopy; Device: The Pentax airwayscope

• Registration Number: NCT01347151
• Lead Sponsor: Prince of Songkla University

Brief Summary

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.

Detailed Description

The primary outcome is the angular displacement of the vertebrae and secondary outcome is the hemodynamic changes after intubation.
