Anaphylactic shock easily confused with which disease

Anaphylactic shock (anaphylaxis, anaphylactic shock) is outside of certain substances into the antigen has sensitized the body, through the immune mechanism in a short period of time in a strong involvement of multiple organ group. Anaphylactic shock performance and level of response by the body, antigen into the volume and channels and are very different. Are usually sudden and very dramatic, if not timely treatment, often life-threatening.

Benbingfasheng soon, it is necessary to make timely diagnosis. Where in the (especially after injection) antigen of the substance or a drug, or bees bites occur immediately after the general reaction, drugs and difficult to explain their pharmacological effects, they should immediately be taken into account the possibility of this disease, it was General little difficult diagnosis. However, it should be except for the following circumstances.

(A) vagus vascular syncope (or vagus vascular collapse, vasovagal collapse) occurred after the injection, in particular, the patients have fever, low blood sugar or the tendency of water loss when. Patients Changcheng looking pale, nausea, a cold sweat, could then syncope, it is easily misdiagnosed as anaphylactic shock. However, this disease no itching or rash, syncope sits flat immediately after the turn for the better, although low blood pressure but slow pulse, and these different anaphylactic shock. Vagal syncope vascular Atropine can be used in the treatment.

(B) edema hereditary vascular disease (hereditary angioedema) This is a regular chromosomes from the lack of genetic complement C1 esterase inhibitor of the disease. In some patients may be non-specific factors (such as infection, trauma, etc.) stimulated a sudden onset, for the performance of the skin and mucous membrane of respiratory vascular edema. As the airway obstruction, patients also often wheezing, short breath and extreme difficulty in breathing, and anaphylactic shock is quite similar. However, the onset of slower, and many patients have family history or history of seizures since childhood, when the disease is usually no blood pressure dropped and no urticaria, which can be differentiated from anaphylactic shock.

Anaphylactic shock of the diagnosis of this specific disease prevention is of great significance, the only test for allergens should be lifted after ① In shock; ② the disabled and Kangguominyao grams of antibody after; ③ such as a skin test, the best necessary Anti-shock drug. A small number of patients with negative skin test is still the possibility of occurrence of this disease.
