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

Not Applicable

Completed

• Conditions: Laryngoscopy; Anesthesia; Intubation
• Interventions: Device: C-MAC videolaryngoscope

• Registration Number: NCT03709979
• Lead Sponsor: Inonu University

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.

Arm && Interventions

Group	Intervention	Description
C-MAC with flat position	C-MAC videolaryngoscope	Children will be intubated by C-MAC videolaryngoscope with flat position (non-inserted a folded towel)
C-MAC with folded towel position	C-MAC videolaryngoscope	Children will be intubated by C-MAC videolaryngoscope with placing a folded towel under the shoulder.

Primary Outcome Measures

Name	Time	Method
Percentage of glottic opening score	immediately before endotracheal intubation	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%

Secondary Outcome Measures

Name	Time	Method
Time to intubation	From beginning of holding videolaryngoscope to seeing two meaningful end-tidal carbon dioxide levels up to 3 minutes	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
