Amer. Miller Conventional Laryngoscope blade 182mm, #4

Clinical Application

This straight Miller blade is designed for direct laryngoscopy to facilitate visualization of the glottic opening and placement of an endotracheal tube. The straight profile and narrow tip allow controlled elevation of the epiglottis rather than relying on indirect tongue displacement, a technique commonly used for patients with anterior laryngeal anatomy or when a direct lift provides a better line of sight. The #4 length (182 mm) corresponds to larger pediatric or adult airway applications where additional blade reach is required.

Design & Configuration

The straight Miller geometry provides a slim midline profile and a narrow distal tip to slide beneath the epiglottis and lift it directly. This configuration minimizes soft-tissue bulk between the blade and laryngeal inlet, improving line-of-sight in certain anatomic presentations. The blade’s length and curvature (or lack thereof) determine insertion depth and the degree of leverage available for epiglottis elevation—factors clinicians consider when selecting blade size for patient anatomy and intubation technique.
