"Live cadavers" for practicing airway management.

Human cadavers have been used successfully as training models to practice airway management, but the lack of lifelike conditions reduces the utility of this model when softness of tissue and the ability to bleed are required for training scenarios. This report describes our "live cadaver" model, which combines lifelike conditions with real human anatomy. Five human cadavers were prepared as "live cadavers". This entailed cannulating the carotid and femoral arteries and the jugular and femoral veins, and then connected them to artificial blood reservoirs. An intra-aortic balloon pump was used to provide pulsating flow through the heart and major arteries. Finally, central and peripheral lines were inserted. Multiple techniques related to airway management were practiced in setting simulating the treatment of casualties with multiple trauma to include emergency cricothyroidotomy. With this model, participants were confronted with medical situations similar to those found in traumatized live patients (e.g., blood and other body fluids filling the mouth and nose, edema of the tongue and face). With the combination of lifelike conditions and real human anatomy, our experience demonstrated that the "live cadaver" increased the training value of traditionally prepared cadaver models. Reprint &
