Brief summary
In this study, the investigators aim to evaluate the glottic visualization and time to intubation during laryngoscopy performed with the C-MAC VL size 1 Miller blade lifting the epiglottis or placing the tip of the blade on the base of the tongue (vallecula) in children younger than 2 years of age.
Detailed description
Direct laryngoscopy (DL) is the most widely used method to ensure airway safety. In pediatric patients under two years of age, Miller laryngoscope blade is recommended as it removes the long and drooping epiglottis from the eye during laryngoscopy and shows the laryngeal entrance better. In the classical definition, the tip of the Miller blade is placed behind the epiglottis. However, if the intubator wishes, the Miller blade tip can be placed on the root of the tongue (vallecula) and used as a Macintosh blade. In the literature search, no study has been found so far comparing C-MAC VL 1 numbered Miller blade with intubation by removing the epiglottis or placing the blade on the vallecula. In this study, the investigators aimed to evaluate the glottic image and intubation time during laryngoscopy performed by lifting the epiglottis with the C-MAC VL No. 1 Miller blade or placing the tip of the blade on the base of the tongue in children under 2 years of age.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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 |
