NUR 229 Lecture Notes - Lecture 2: Type I Hypersensitivity, Septic Shock, Distributive Shock
Document Summary
It occurs due to the introduction of an allergen in the body. This leads to mast cells or basophils to release histamine and other chemicals system-wide. This will decrease tissue perfusion causing shock to occur. Anaphylactic shock is a form of distributive shock. The other types distributive shock are neurogenic and septic shock. An allergen can enter various ways such as via an: injection, inhalation, oral, or contact with the skin. Known substances that can cause anaphylactic shock: foods (shellfish, peanuts, eggs, milk, medications (vaccines, contrast dye, nsaids, antibiotics penicillin) Insect venom: latex, physical exercise, unknown cause: idiopathic . Now, let"s talk about what is occurring during anaphylactic shock, and to do this we need to talk about the two types of reactions that can lead to anaphylactic shock. Anaphylactic shock can occur either due to an immune response where ige antibodies are created or due to a non-immune response.
