Comparing the Laryngoscopy View Using Miller and Macintosh Laryngoscopy Blades in Infants Under Two Years of Age

Completed · Not applicable

Conditions studied: Percent of Glottic Opening

In brief

To compare the laryngoscopy view using two standard clinical devices, the Macintosh and Miller laryngoscopy blades, in infants between one day and two years of age. Miller blades (straight blades) are more commonly used than MacIntosh blades (curved) in pediatric clinical practice in some institutions especially in infants. The anatomy of infant airway has traditionally been considered to lend itself to advantages of the Miller blade. Some argue that the Miller blade offers a superior view of the laryngeal inlet because it lifts the epiglottis. However, others use the Miller blade to expose the larynx without lifting the epiglottis, supposedly to avoid traumatizing it. Despite the long-standing use of these blades, more than 50 years, no systematic study has ever compared the laryngoscopy views of the Miller and Macintosh blades in infants.
