Description
Allergy to anesthetics is a reaction of the immune system to drugs that are used for loss of sensitivity or pain. Anesthetics can be administered locally (applied to a certain part of the body or injected under the skin), and also systemically – injected into the bloodstream.
There are two main types of allergic reactions to anesthetics:
- reactions of the immediate (I) type – occur within a few minutes after the introduction of an anesthetic and are caused by immunoglobulin E (IgE), released by the immune system in response to an allergen;
- reactions of the delayed (IV) type – occur several hours or days after the introduction of the anesthetic and are caused by T cells, a variety of leukocytes.
To avoid excessive contact with the allergen, it is better to conduct a blood test to assess the level of IgE. The determination of specific immunoglobulin E to a certain allergen in an increased amount indicates the presence of sensitization of the body to it. The obtained results help in the diagnosis of type I (immediate) allergy.
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.
