| خلاصه مقاله | Anaphylaxis is defined as a serious allergic reaction that is rapid in onset and may cause death. Anaphylaxis in children, particularly infants, is underdiagnosed. It can happen seconds or minutes after you’ve been exposed to something you’re allergic to. Peanuts or bee stings are examples. In anaphylaxis, the immune system releases a flood of chemicals that can cause the body to go into shock. Blood pressure drops suddenly, and the airways narrow, blocking your breathing. The pulse may be fast and weak, and you may have a skin rash. You may also get nauseous and vomit. Anaphylaxis needs to be treated right away with an injection of epinephrine. If it isn’t treated right away, it can be deadly. Anaphylaxis is a severe, potentially life-threatening allergic reaction. It can occur within seconds or minutes of exposure to something you're allergic to, such as peanuts or bee stings.
Anaphylaxis is characterized as a life-threatening systemic allergic reaction that can include a range of clinical signs and symptoms. Although anaphylaxis is not an infrequent occurrence, with a lifetime prevalence estimated at 1.6% to 5.1%. Diagnosing anaphylaxis relies on a thorough clinical history that includes patient characteristics (eg, age, sex, medical and atopic history, concurrent medications), detailed description of the reaction (possible triggers, symptom pattern, timing of onset duration of symptoms), concomitant factors (eg, exercise, viral infection, medications, menstrual status, stress, food, alcohol), and response to treatment. |
