Abstract

In a prehospital setting, the narrow therapeutic window of epinephrine necessitates its cautious administration to avoid anaphylaxis. In this case, a 46-year-old man presented severe anaphylactic symptoms. Following the standard protocol, the emergency medical technician (EMT) administered intramuscular epinephrine; however, symptoms persisted. Under the oversight of the emergency medical services (EMS) medical director, an additional intravenous bolus of epinephrine was administered, unfortunately leading to atrial fibrillation. This case underscores the potential risks of intravenous epinephrine, which is not typically recommended for anaphylaxis without continuous monitoring. Since 2019, Korea has initiated a pilot program to expand the EMT scope of practice, which gives them the authority to administer epinephrine for anaphylaxis. The ultimate decision regarding epinephrine use for anaphylaxis, emphasizing patient safety, rests with the EMS medical director. Proper training for EMTs, coupled with the EMS medical director’s comprehensive knowledge and meticulous protocol adherence, can ensure patient safety and optimal outcomes.
