Do it in the wild outdoor sport They are often bitten by poisonous insects and animals, such as snakes, bees, centipedes, etc.

Snakebite

There are two kinds of snake venom: nerve venom and blood venom. When a snake bites, the bitten limb should be lowered, and the wound should be tied gently with a tie at the end near the heart. If there is no wound of tongue, gum collapse or cleft lip in the mouth, you can inhale the wound 10 times, spit out the blood immediately after each mouthful, and finally rinse the mouth. While treating the wound, it is necessary to take and apply snake medicine to the wound in time. The wound should be kept still. In case of foot injury, it should be carried to the hospital. It is dangerous to be bitten by a poisonous snake, and the bite by a non-toxic snake must also be treated in time.

Bee sting

If you are stung by a bee when you go hiking in summer and autumn, don't think it's nothing. Attention should be paid, which sometimes leads to serious consequences. If the bee venom enters the blood vessel, anaphylactic shock will occur, leading to death.

First aid measures:

1. After being stung by bees, the venom needle will stay in the skin. The broken sting in the meat must be removed with a disinfection needle, and then the stung part must be pinched forcefully, and repeated sucking with the mouth to suck out the toxin. If there is no medicine around, wash the affected part with soapy water, and then apply some vinegar or lemon.

2. In case of shock, when notifying the emergency center or on the way to the hospital, pay attention to keeping breathing unblocked, and carry out emergency treatment such as artificial respiration and heart massage.

Precautions:

1. After being stung by a poisonous bee, it is basically ineffective to apply ammonia to the affected area. Among the poisonous insects, only the wasp is different, and its toxin is alkaline. Because the histamine of bee venom cannot be neutralized by ammonia, after pulling out the sting, the wound is sterilized with iodine and alcohol. You can take some anti allergy drugs.

2. After being stung by bees, the broken sting should also be removed first. Different from wasps in treatment, some ammonia, baking soda or soapy water can be applied to the wound to neutralize the toxin.

Centipede bite

The centipede belongs to the class Polypoda. The first pair of feet is hook shaped and sharp. The mouth of the poisonous gland at the end of the hook is generally called palatal tooth, tooth claw or poisonous limb. It can discharge poison. After being bitten by the centipede, its poison gland secretes a large amount of poison. The mouth of the poison gland along the palatal tooth is injected into the skin of the bitten person, causing poisoning.

Clinical manifestations:

The bite of small centipede can only cause redness, swelling and pain in the local area. The bite of tropical large centipede can cause lymphangitis and tissue necrosis, and sometimes the whole limb appears purpura. Some can see headache, fever, dizziness, nausea, vomiting, and even mutton, convulsions, coma and other systemic symptoms.

Emergency treatment:

Clean the wound with soapy water immediately after the centipede bite, apply cold wet dressing to the wound locally, or use houttuynia cordata and dandelion for external application. Those with systemic symptoms should go to the hospital for treatment as soon as possible.

Scorpion bite

Scorpions belong to arachnida. When scorpions sting people, they secrete venom from the venom glands into the human body, which quickly causes a series of toxic reactions.

Emergency treatment:

Scorpion venom is acidic. You can apply alkaline soapy water (don't use soap), soda water and 3% ammonia to the wound, if there is snake medicine. Apply warm boiled water to the wound, and apply myrrh to the cold tea (alkaline). Tie the upper part of the injured limb 2-3 cm with cloth tape and relax for 1-2 minutes every 15 minutes. Ice can be applied around the wound, cut the skin of the wound, suck out the venom with an aspirator or cupping tin, and use potassium permanganate solution and lime water to wash the wound. Those with severe symptoms should go to the hospital for treatment.

Spider

There are many kinds of spiders with different toxicity, including neurotoxin, cytotoxic, hemolytic, etc.? After biting, the wound is extremely painful, bleeding, and even leads to unconsciousness. Spider venom is also acidic. The treatment method is the same as that of scorpion. The earlier the better.

Dog or cat bites

After being bitten, immediately wash with clean water and soap, wrap gauze and go to the hospital for inspection. The wound bitten by a dog is easy to fester, so it must be thoroughly treated and vaccinated in time.
