Tongue extrusion as an aid to blind nasal intubation

Abstract

Blind nasal intubation often results in esophageal placement of the tube because reflex swallowing and supralaryngeal structures direct the tube posteriorly. Extrusion of the tongue, which inhibits swallowing and shifts the supralaryngeal structures anteriorly, facilitated blind placement of a nasotracheal tube in 14 of 16 critically ill patients. The technique avoids manipulation of the neck, the use of heavy sedation or anesthesia, and requires no specialized training or equipment.
