Although complications during anesthesia are rare, potentially life-threatening consequences may occur if an anaphylactic reaction develops. The severity of the reaction whilst under anesthesia is because the anesthetist is only made aware of the allergy when it is severe enough to compromise the cardiovascular system and the respiratory system.
Anaphylactoid reaction, non-immune anaphylaxis, or pseudoanaphylaxis, is a type of anaphylaxis that does not involve an allergic reaction but is due to direct mast cell degranulation. [ 10 ] [ 42 ] Non-immune anaphylaxis is the current term, as of 2018, used by the World Allergy Organization [ 42 ] with some recommending that the old ...
Signs and symptoms of anaphylaxis. Food allergy symptoms occur within minutes to hours after exposure and may include: [11] Rash; Hives [11] Itching of mouth, lips, tongue, throat, eyes, skin, or other areas [11] Swelling of lips, tongue, eyelids, or the whole face [11] Difficulty swallowing [11] Runny or congested nose [11] Hoarse voice [11]
The treatment of immediate hypersensitivity reactions includes the management of anaphylaxis with intramuscular adrenaline (epinephrine), oxygen, intravenous (IV) antihistamine, support blood pressure with IV fluids, avoid latex gloves and equipment in patients who are allergic, and surgical procedures such as tracheotomy if there is severe ...
Type I hypersensitivity (or immediate hypersensitivity), in the Gell and Coombs classification of allergic reactions, is an allergic reaction provoked by re-exposure to a specific type of antigen referred to as an allergen. [1] Type I is distinct from type II, type III and type IV hypersensitivities. The relevance of the Gell and Coombs ...
They found that the IgE antibody response to the mammalian oligosaccharide epitope alpha-gal was associated with both the immediate-onset anaphylaxis during first exposure to intravenous cetuximab and the delayed-onset anaphylaxis 3 to 6 hours after ingestion of mammalian food products, such as beef or pork.
An example of a tuberculosis (TB) infection that comes under control: M. tuberculosis cells are engulfed by macrophages after being identified as foreign but, due to an immuno-escape mechanism peculiar to mycobacteria, [4] TB bacteria block the fusion of their enclosing phagosome with lysosomes which would destroy the bacteria. Thereby TB can ...
Increasing the IV fluids during surgery by giving additional fluid while the person is under general anaesthesia may reduce the risk of nausea/vomiting after surgery. [1] For minor surgical procedures, more research is needed to determine the risks and benefits of this approach.
