Effect Of Position On Laryngeal Visualisation With The C-Mac Videolaryngoscope

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to demonstrate the effect of C-Mac videolaryngoscopy with Miller Blade size 0 and 1 on the intubation conditions in children less than 2 years age with a roll inserted under the shoulders.

Detailed Description
-----------------
The laryngoscopic view of the glottis is improved when the angle of the line of vision between the pharyngeal - laryngeal axis and the oral cavity axis is narrow. A roll inserted under the shoulders of the infant will help line up the oral, laryngeal, and pharyngeal axes making direct laryngoscopy easier. The investigators hypothesized that laryngoscopic view and intubation conditions using C-Mac videolaryngoscope with Miller Blade size 0 and 1 would be better with a roll under shoulder in children under 2 years.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: C-MAC with folded towel position<br>Children will be intubated by C-MAC videolaryngoscope with placing a folded towel under the shoulder. | Device: C-MAC videolaryngoscope<br>* An intubating device that is used for endotracheal intubation. Endotracheal intubation will be performed by anesthesiologist with C-MAC videolaryngoscope<br>|
| Placebo Comparator: C-MAC with flat position<br>Children will be intubated by C-MAC videolaryngoscope with flat position (non-inserted a folded towel) | Device: C-MAC videolaryngoscope<br>* An intubating device that is used for endotracheal intubation. Endotracheal intubation will be performed by anesthesiologist with C-MAC videolaryngoscope<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of glottic opening score | Percentage of glottic opening score of 100% denotes visualization of the entire glottis, from the anterior commissure of the vocal cords to the inter-arytenoid notch. If no part of the glottic opening was visualized, the POGO score was recorded as 0% | immediately before endotracheal intubation | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to intubation | Time to intubation will be measured from the time the videolaryngoscope entered the patient's mouth until the first capnograph trace is seen on the monitor | From beginning of holding videolaryngoscope to seeing two meaningful end-tidal carbon dioxide levels up to 3 minutes |
