Using a modified nasotracheal tube to prevent nasal ala pressure sore during prolonged nasotracheal intubation.

Nasotracheal tube induced nasal ala pressure sores or necrosis during prolonged nasotracheal intubation have been reported, and it is a serious but preventable complication. Here we introduce a modified nasotracheal tube to prevent this complication. This modified nasotracheal tube is composed of two parts, an oral endotracheal tube and a proximal part of a preformed nasotracheal tube, which are linked by a connector. The use of this modified nasotracheal tube can prevent nasal ala pressure sores during prolonged nasotracheal intubation.
