Allergic reactions to local anesthetics

Abstract

In this article type I and type IV allergic reactions evoked by local anaesthetics are discussed. Contact dermatitis (type IV) reactions are mainly caused by local anaesthetics of the ester-type like procaine. Both contact dermatitis and anaphylactic reactions (type I) can be caused by anaesthetics of the amide-type (e.g. lidocaine), but these reactions are rare. Intra- and epicutaneous tests can be useful to prove allergy, but sometimes provocation tests are necessary. Many reactions are not caused by an allergic mechanism.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.

Anaphylaxis

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.
