Epistaxis With Warfarin Coagulopathy: An Adult Simulation Case for Residents.

Introduction: Epistaxis is a common presenting complaint in the emergency department. Proper technique to control the bleeding is essential. Active bleeding on an anticoagulant requires special consideration. Blood products and coagulopathy reversal are an important part of the resuscitation of an unstable bleeding patient on warfarin.

Methods: This resource was created to simulate a high-acuity and moderate-frequency event seen in emergency departments and on hospital wards. The target audience included emergency department residents, internal medicine residents, and advanced practice providers. The scenario detailed the case of an 82-year-old male on Coumadin who presented with epistaxis. A mannequin equipped with an epistaxis task trainer in which rate of bleeding could be controlled was required. The case was complicated by a choking episode on attempted nasal packing. It also involved warfarin coagulopathy requiring blood products and warfarin reversal. The simulation may be performed in a simulation lab or in situ in the emergency department, intensive care unit, or medical floor. Critical actions include addressing epistaxis with packing, recognizing blood-loss anemia related to warfarin coagulopathy, and recognizing and managing airway obstruction.

Results: Approximately 35 learners completed this module in five separate sessions. Written evaluation from learners showed that 95% felt the simulation scenario and debriefing were effective.

Discussion: Simulation is an ideal teaching tool for this life-threatening presentation. Learners can demonstrate proper technique and management of this difficult case.
