Managing Anaphylaxis in the Emergency Department Contents

Anaphylaxis	A serious systemic hypersensitivity reaction that is usually rapid in onset and may cause death. Severe anaphylaxis is characterized by potentially life-threatening compromise in airway, breathing and/or the circulation, and may occur without typical skin features or circulatory shock being present.
Antihistamine drugs	Class of drugs that blocks the action of histamines, for symptomatic relief of associated manifestations such as fever, skin rash, itching, sneezing, a runny nose, and watery eyes.
Bronchia Asthma	A chronic inflammatory disease of the airways characterized by bronchial hyperreactivity and a variable degree of airway obstruction. It is diagnosed on the basis of the clinical history, physical examination, and pulmonary function tests, including reversibility testing and measurement of bronchial reactivity.
Corticosteroids drugs	Corticosteroids are synthetic analogues of the natural steroid hormones produced by the adrenal cortex, specifically glucocorticoids, which act by binding to intracellular receptors. Upon activation, it inhibits gene expression and translation in inflammatory leukocytes and structural cells, such as epithelium.
