Description
Anesthetic allergy is a reaction of the immune system to drugs that are used to cause loss of sensation or pain.Anesthetics can be administered locally (applied to a specific area of the body or injected under the skin) or systemically introduced into the bloodstream.
There are two main types of allergic reactions to anesthetics:
- immediate (I) type reactions – occur within a few minutes after the administration of the anesthetic and are caused by immunoglobulin E (IgE), released by the immune system in response to the allergen;
- delayed (IV) type reactions – occur several hours or days after the administration of the anesthetic and are caused by T cells, a type of white blood cell.
To avoid excessive contact with the allergen, it is better to conduct a blood test to assess IgE levels. Determination of specific immunoglobulin E to a certain allergen in increased quantities indicates the presence of sensitization of the body to it. The results obtained help in diagnosing type I (immediate) allergies.
When and who needs the test?
- suspicion of an allergy to anesthetics based on previous reactions or medical data;
- previous history of allergic reactions, especially to anesthetics; • strange reactions to anesthetics;
- planned medical procedures using anesthetics;
- systemic allergic reactions to other allergens.
Performing this study is safe for the patient compared to skin tests (in vivo), since it eliminates the patient's contact with the allergen.
