Tracheal Intubation in Patient With Semi-rigid Collar Immobilization of the Cervical Spine: A Comparison of Fiberoptic Bronchoscope Assisted With Pentax-airway Scope and Fiberoptic Bronchoscope Alone

Study Overview
=================
Brief Summary
-----------------
A semi-rigid cervical collar is recommended for immobilization of the cervical spine in patients with cervical spine injury. It has been suggested that a reduction in mouth opening is the major contributing factor to the deterioration in the glottic view obtained. Fiberoptic intubation is among the most versatile techniques for managing both the anticipated and the unanticipated difficult airway. Recently, combination of fiberoptic bronchoscope with videolaryngoscope has been suggested to permit visual control of the passage of the tube over the fibrescope into the laryngeal inlet. The aim of this study is to compare the intubation time and ease of intubation between fiberoptic bronchoscope alone and bronchoscope with pentax airwayscope.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| time to intubation |  | Time from device passing the mouth until confirmation of tracheal intubation by bronchoscope will be measured, about 2 minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| ease of intubation | Numeric rating scale 0-10 (0:easy without any difficulty, 10: impossible to intubate) | Numeric rating scale will be assessed by practioner of fiberoptic bronchoscope for intubation immediately after intubation. |
