What type of blade should be used when intubation on an infant or small child?

In infants, the airway anatomy makes direct visualization easier with a straight blade. A Miller blade is designed to lift the epiglottis directly with the blade tip, which is particularly helpful when the epiglottis is large and floppy and the larynx is high and anterior. This direct lift often provides a clearer view of the vocal cords with less maneuvering in very small mouths. Curved blades lift indirectly via the vallecula, which can be less reliable in tiny airways, and pediatric curved blades are just smaller versions of that design. Video laryngoscopy can be used, but it’s a different device rather than a blade option.
