Abstract:
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.
