The Conditions and Improvement Plan for 119 EMS Activities with Anaphylactic Reaction Patients: Focused on Daejeon Metropolitan City

This study examined the current state of emergency services (EMS) provided to patients experiencing anaphylactic reactions based on 119 EMS activity reports and proposed improvement measures. From January 1, 2021, to December 31, 2021, a total of 106 individuals with anaphylactic reactions in a metropolitan city were analyzed. The results showed that the most frequent locations for anaphylaxis were homes, mountains, and fields, with bee stings identified as the leading cause. Among the individuals with anaphylactic reactions, 26.4% were classified as severe, 36.8% as moderate, and 36.8% as mild reactions. Severe anaphylactic reactions were associated with increased cardiovascular and respiratory clinical manifestations. Implementation rates for cardiac rhythm monitoring and oxygen, fluid therapy, antihistamine, and epinephrine administration were 21.4%, 46.3%, 28.6%, 3.6%, and 7.1%, respectively. It is crucial to identify the suspected causative agent through accurate medical history taking to improve outcomes. Early prediction of severe anaphylaxis based on a patient’s clinical manifestations and vital signs after exposure is essential to ensure intensive monitoring and appropriate emergency treatment.
