Inappropriate use of intravenous epinephrine leading to atrial fibrillation during prehospital anaphylaxis treatment: A case report.

ABSTRACT

In a prehospital setting, the narrow therapeutic window of epinephrine necessitates its cautious administration for anaphylaxis. In this case, a 46-year-old man presented severe anaphylactic symptoms. Following standard protocol, the emergency medical technician (EMT) administered intramuscular epinephrine; however, symptoms persisted. Under the oversight of the emergency medical service (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 isn't typically recommended for anaphylaxis without continuous monitoring. Since 2019, South Korea has initiated a pilot program to expand the EMT's 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.
