Cuffed nasopharyngeal tube as 'dedicated airway' in difficult intubation.

Abstract

A cuffed nasopharyngeal airway was used in five cases of difficult intubation, initially to maintain anaesthesia, and subsequently to act as a landmark for the passage of a fibreoptic laryngoscope loaded with a tracheal tube. In all cases, airway patency was well preserved with the device and there were no significant problems with its use. The notion of a 'dedicated airway' for difficult intubation cases is developed. A trouble-free airway will permit time to consider solutions for difficult cases and time for the novice to learn fibreoptic laryngoscopy technique.
