RESUMO
Anaphylaxis is a medical emergency and all healthcare professionals need to be familiar with its diagnosis, acute management, long-term management including prevention of future episodes, and plan for patient education. Correct diagnosis and management for anaphylaxis is critical, but it is not easy in clinical setting. Up to the present, several practical guidelines for anaphylaxis are available for the practitioners. Among them, World Allergy Organization guideline for the assessment and management has recently been released and widely used. In this article, we reviewed and summarized the epidemiology, risk factors, diagnosis, management, prevention, and education based on case reports and studies of anaphylaxis in Korean and other countries. Although there are many controversies, this practical overview for anaphylaxis would provide a clinical guidance for Korean healthcare professionals.
