Anaphylaxis is the quintessential critical illness in emergency medicine. Symptoms are rapid in onset and death can occur within minutes. Approximately 1500 patients die annually in the United States from this deadly disorder. It is imperative, therefore, that emergency care providers be able to diagnose and appropriately treat patients with anaphylaxis. Any delays in recognition or initiation of therapy can result in unnecessary increases in patient morbidity and mortality. ⋯ For patients with anaphylaxis, rapid and appropriate administration of epinephrine is critical for survival. Additional therapy, such as supplemental oxygen, intravenous fluids, antihistamines, and corticosteroids should not delay the administration of epinephrine.
