In pediatric intubation, which blade type is historically associated with easier epiglottis manipulation?

• A. Curved blade
• B. Straight blade
• C. Video laryngoscope
• D. Laser blade

Answer: (B)

The blade design that historically makes lifting the epiglottis easier in pediatric intubation is the straight blade. Straight blades are shaped to lift the epiglottis directly with the blade tip, which exposes the glottic opening more reliably in children. In young patients, the airway is higher and more anterior, the epiglottis tends to be larger and more floppy, and the vallecula (the pocket between the tongue base and epiglottis) is less developed. Because the straight blade elevates the epiglottis directly, you get quicker, clearer visualization of the vocal cords without depending as much on a well-formed vallecula. By contrast, a curved blade works by lifting the epiglottis indirectly via the vallecula, which can be less effective in children due to the anatomical differences mentioned. Video laryngoscopy can aid visualization but isn’t as specifically about epiglottis manipulation, and a laser blade isn’t used for routine pediatric intubation.
