NCT03112798

Brief Summary

Miller blades are commonly used in pediatric anesthesia; however, there is less evidence-based information on the superiority of Miller blades in the visualization of the laryngeal inlet to Macintosh blades. The aim of the present study is to compare the glottic views with the size 0 Macintosh and Miller laryngoscope blades above and below the epiglottis.
