The redness and swelling of the affected area disappear.

This method is economical, simple, and very fast.

First, the main reason is that centipede is also known as a hundred limbs and a dragon. It mostly lives in rotten wood and stone crevices or barren and damp places, day and night, and there are more in the south of our country. It secretes poisonous juices containing histamine and hemolytic proteins.

When a person is bitten by it, its poisonous juice passes through the tip of its claw and is injected into the human body and poisoned.

2. Judgment. Centipede bites are mostly in hot weather, and the bite site is red, swollen, painful, blistered, necrosis, lymph nodes, lymphangitis, fever, nausea, vomiting, headache, dizziness, coma and shock.

Centipede is a terrestrial myriapod arthropod, commonly known as a hundred legs, the body is flat and long, the ventral dorsum is about 20 segments, each body segment has a pair of feet, the first pair of feet is hook-shaped, sharp, hook end of the poisonous glandular mouth, located in the mouthparts straight behind, so it is generally called the palatine teeth or venomous limbs, can discharge venom. Centipedes are afraid of sunlight and prefer damp places, mostly inhabiting rotten wood, stone crevices or damp grass, and occasionally hiding in clothing. When people work outdoors or play with children, they can be bitten by centipedes, causing poisoning in the damp and unclean room, and centipedes can also sneak in, resulting in bite poisoning incidents.

When bitten by a centipede, its venom gland secretes a large amount of venom, which is injected under the skin of the bitten person along the venom gland mouth of the palate teeth. The larger the centipede, the more toxin is injected into the sting, and the more severe the poisoning symptoms. Centipede venom is acidic and contains two toxic components that resemble bee venom, a histamine-like substance and a hemolytic protein; In addition, it also contains tyrosine, formic acid, fatty oil, cholesterol, etc.

A centipede bite can cause local tissue destruction and lymphangitis, and venom also has a sensitizing effect, sometimes causing a large area of purpura.

Assessment of the severity of centipede bitesThe severity of centipede bites should take into account the following factors: The size of the centipede is related to the amount of venom injected. Local symptoms and manifestations of systemic toxicity.

Manifestations of allergic reactions. 1. Small and medium-sized centipede bites have local pain, there is a white round bulge at the bite site, followed by flushing, edema, epidermal necrosis, and lymphadenitis, which generally improve and disappear within 1 to 3 weeks. Some patients are not effective**, and there is still local swelling and itching 1 month after the injury.

2. Large centipede bites are locally burning and swollen, severe pain, and unbearable burning pain. In severe cases, local blisters or necrosis may occur, and there may be significant lymphatic vessels and lymphadenitis. Systemic toxicity can also occur after toxin absorption.

Such as dizziness, dizziness, nausea, vomiting, fever, etc., and even delirium, convulsions, coma. Young children often have severe systemic symptoms because of their low body weight. 3. Allergic reactions Some patients have anaphylactic reactions similar to bee venom, with allergic symptoms, and even anaphylactic shock, and fatal cases have been reported.

Breeders to prevent being stung and poisoned by centipedes: keepers should use small shovels or other agricultural tools to turn over the upper blocks or gravel when catching centipedes, and quickly use special clips made of iron and bamboo to catch centipedes when they are found, so as to prevent them from being stung and poisoned. If you are accidentally stung when catching, you can squeeze out the poisonous juice first according to the situation, and simply**:(1) Apply the juice of salt skin wood to the abrasion; (2) After igniting with yellow straw paper roll salt, blow the soot from the other end of the paper roll to the affected area; (3) Apply ammonia or toilet water to the wound; (4) Rub the wound with egg white or rooster saliva; (5) Rub the mucus on snails, slugs, and earthworms; (6) Wipe with cool oil; (7) Mix garlic juice and mulberry juice with white salt; (8) Mash with shredded cigarettes and mix with tea oil; (9) Wipe the affected area with freshly populated centipede mashed and mixed with tea oil; (10) Apply slices of alkaline water or shallots to the wound.
