Abstract:
Twenty-seven anaesthesia faculty, fellows and residents compared a standard intubating mannequin and an anaesthetized pig as models for teaching fibreoptic tracheal intubation. When likened to the clinical situation, the anatomic characteristics of the pig airway were rated as significantly more realistic than the airway characteristics of the mannequin with the exception of the appearance of the epiglottis. In addition, the overall score for the pig model was significantly higher than the score for the mannequin and 26 of 27 evaluators rated the anaesthetized pig as the more effective teaching model. We conclude that an anaesthetized, spontaneously breathing pig is a valid model for teaching fibreoptic endotracheal intubation.
