Abstract

As educators, we are charged with preparing emergency medicine residents for successfully intubating patients with even the most troublesome anatomy. This situation is encountered during the intubation of patients with angioedema. These patients are uncommon in the emergency department, and as a result, it is difficult to ensure that each resident is well trained in this intubation scenario before graduation. Our goal was to develop an angioedema teaching model to increase resident knowledge, confidence, and proficiency at intubating in this clinical setting. Using a 22-gauge spinal needle and a 60-mL syringe, we were able to cause realistic distention of the lips, tongue, and pharynx when we injected approximately 300-mL of air bilaterally near the sublingual glands and into the tongue and lips. Before implementing the angioedema model into the curriculum, 5 board-certified attending emergency physicians evaluated the model for validation, and all agreed that it was high fidelity.Participants performed both direct and video laryngoscopy on the simulated angioedema cadaver. At the conclusion of their intubation experience, the participants completed a survey describing their impression of the angioedema model. Participants incl...Continue Reading
