Antivenom serum is a purified antibody produced by animals after injecting a small amount of snake venom into animals for many times, which contains high-valent antivenom antibody. Bitten by a snake, snake venom enters the body and is an antigen for people.
The injected antitoxin serum contains corresponding antibodies, which can neutralize the corresponding snake venom and form a complex by specific binding, so that the toxin loses its activity and is processed by the corresponding phagocytes of the body, thus making the toxin useless to people. Therefore, after being bitten by a poisonous snake, it is more beneficial to the body to inject antivenom in a short time after the initial treatment of the wound.
Special attention should be paid to prevent allergic reactions when using antiserum. Before injection, you must do an allergy test and ask about your past allergy history in detail. Anyone who has a history of bronchial asthma, hay fever, eczema or angioneurotic edema, or who is allergic to certain substances, or who has been injected with horse serum preparation in the past, must be especially alert to allergic reactions.
