Simulation study of nasotracheal and orotracheal fiberoptic intubation with the Aintree Intubation Catheter.

Aim: Fiber-optic tracheal intubation is an essential technique to secure the airway for difficult airway and cervical cord injury victims. However, there is an anxiety about the vocal cord passage of tracheal tubes because of the potential of collision with the surroundings of the vocal cords. This study aimed to examine the utility of the Aintree Intubation Catheter in nasotracheal and orotracheal intubation.
