Anaphylaxis is a severe and life-threatening reaction to certain allergens, which is accompanied by severe pain, swelling, muscle spasms and suffocation. The reaction may occur after the insect bite and after medication or interactions with other allergens.
Causes and symptoms of anaphylaxis
Symptoms of anaphylaxis may occur immediately or several hours after the allergic contact. The most common symptoms of anaphylaxis often are swelling, severe pain, muscle spasm, redness, skin rash, itching, nausea, vomiting, swelling of the respiratory system.
Late symptoms are bronchospasm, hoarseness and difficulty breathing, hypoxia, hives, heart palpitations. The heart begins to work erratically with faults and wrong cut. If the patient does not help, then anaphylaxis leads to a sharp drop in blood pressure, loss of consciousness and death.
The main cause of anaphylaxis is a specific allergen, a role which may make medicines and their ingredients, insect venom, animal dander, pollen, foods, etc. Sometimes the first contact with the allergen anaphylaxis is not shown, but with repeated interaction is developing quite quickly.
Allergy and Anaphylaxis influence each other from the presence of the allergen. Anaphylaxis can occur in contact with the allergen in a person's blood and react with immunoglobulin, which results in the release of histamine and formation of the inflammatory process.
The causes of anaphylaxis may be narcotic drugs, and contrast agents, aspirin and non-steroidal drugs that cause anaphylactoid reactions in people with chronic diseases. Allergy and anaphylaxis are closely related, since patients with allergic reactions are often susceptible to anaphylactic shock.
The main types of anaphylaxis
Anaphylaxis has several types, depending on the type of allergen. The disease can be divided into several categories:
- food reaction;
- reaction to anesthesia during surgery and rehabilitation;
- idiopathic reaction;
- dosage, drug response, and Nonsteroidal;
- response to exercise;
- reaction to the flora and fauna.
If symptoms of anaphylaxis should immediately identify the type of allergen and start treatment. After suffering anaphylactic shock in a patient for several years is at risk of re-reaction.
Treatment of Anaphylaxis
Treatment of anaphylaxis is performed on an emergency basis and consists of introducing a certain dose of adrenaline. Patients who have chronic allergies and suffered anaphylactic shock, you need to carry a syringe of adrenaline.
If persistent symptoms of the disease need urgent hospitalization and intensive care. The patient should be under the constant supervision of medical specialists to the stabilization of the physical condition.
After anaphylaxis doctor oversees the functioning of the cardiovascular system, brain, respiratory system and digestive system. The patient regularly measure blood pressure and pulse, as well as appoint a full diagnostic examination.
To prevent recurrence of anaphylaxis prescribe immunotherapy that is intended to control exposure to allergens and preventing development of inflammatory processes.
