The Laryngoscopic View With C-MAC Videolaryngoscope Miller Blade Lifting the Epiglottis or the Vallecula in Children

Inönü University Department of Anesthesia

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.

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.
