Brief summary

The purpose of this study is to investigate whether the difference in stylet curvature affects the ease of tracheal intubation using C-MAC videolaryngoscope in infants under 1 year of age.

Interventions

OTHERStyle curve similar to natural curvature of endotracheal tube

Stylet curvature is made similar to the natural curvature of endotracheal tube for intubation using C-MAC videolaryngoscope.

OTHERStyle curve similar to hockey stick shape

Stylet curvature is made similar to hockey stick shape for intubation using C-MAC videolaryngoscope.
