Robert Arden Miller (1906 – 1976)

Robert Arden Miller (1906 – 1976) American anesthesiologist.

Designed the Miller laryngoscope blade, first manufactured by the Welch-Allyn Company in 1941

When Miller created his blade, most specialist anaesthetists were familiar with the advantages of endotracheal intubation, especially since the widespread use of closed-circuit cyclopropane anaesthesia. Miller’s contribution was to make changes to pre-existing blades to make endotracheal intubation more certain. Miller recommended the use of a stylet rather than forceps when inserting larger, cuffed tubes using a Miller blade, as the mouth did not open as widely.

Medical Eponyms

Miller laryngoscope blade (1941)

The Miller laryngoscope is a narrow-lumen, D-shaped, straight-blade designed to obtain a view of the vocal cords by directly lifting the epiglottis. It has useful application in ‘floppy’ airways making it popular within paediatric anaesthesia.

Miller found traditional straight blades to be too thick at the base and too short increasing the risk of trauma to the teeth. Miller modifed the laryngoscopes popular at the time to make tracheal intubation “easier and more certain”. The Miller laryngoscope has a straight blade with a long, curved tip, providing better exposure of the larynx. This made difficult intubations easier to perform and minimised dental trauma.

Miller designed his blade by making it straight and longer than the old style medium blade, rounded at the bottom and smaller at the tip with an extra curve two inches from the end. This made difficult intubations easier to perform and minimised dental trauma. He found this suitable for all patients; except children.

In 1946, Miller developed a blade for use in children. He recommended that tracheal intubation under direct visualization was preferable to the common practice of blind passage facilitated by digital palpation of the epiglottis
