Postintubation hoarseness and sore throat

due to mechanical presence of the tracheal tube

Preparation of Equipment

Assemble pharyngeal airways in assorted sizes



Inspect laryngoscope for serviceability


Light bulb

Blades; curved/straight (Macintosh or Miller)

Selection of laryngoscope blade (preference)

Macintosh is a curved blade whose tip is inserted into the vallecula (the space between the base of the tongue and the pharyngeal surface of the epiglottis). Most adults require a Macintosh number 3 or 4 blade.

Selection of laryngoscope blade (preference)

Miller is a straight blade that is passed so that the tip of the blade lies beneath the laryngeal surface of the epiglottis. The epiglottis is then lifted to expose the vocal cords. Most adults require a Miller number 3 blade.
