What to do if a spider sprays a person and blisters

What to do after being bitten by a venomous spider.

If you are bitten by a spider in general, there will be only slight pain in the wound area, and no serious adverse reactions will occur. But if you are bitten by a red spotted spider, it is not trivial. The red spotted spider, also known as the black widow, belongs to the family of arthropods, arachnids, arachnids, and bead-bellied arachnidae.

Because the first pair of appendages have stinging teeth at the top of the upper end, when it bites, it can stab the person's **, and then inject the venom secreted in the venom gland into the wound through the sting, causing poisoning. Poisoning is characterized by localized swelling, pallor, rash, pain, and muscle spasms. Systemic reactions include lack of energy, malaise, dizziness, headache, salivation, nausea, vomiting, chills, fever, night sweats, hand and foot spasms, cyanosis, increased blood pressure, and other symptoms, and in severe cases, dyspnea.

Stiffness of the muscles in the abdomen, lower back, or back, extreme irritability, obscured reflexes, miosis or delirium, confusion, shock, and even death.

The first aid measures are:

1. Local treatment of the wound: after being bitten by the red spider, the tourniquet can be stretched on the wound, loosened once every 15 30 minutes, and then stretched again after about 2 3 minutes. If the body part is bitten, 0 5 procaine can be used as a ring seal.

At the same time, the wound is enlarged (the same as a venomous snake bite), the venom is suctioned, and then cauterized with carbolic acid; The wound can be compressed with Nantong snake medicine or herbal lobelia.

2. Whole body**: intravenous infusion of glucose saline can accelerate the excretion of poisons. 10 ml of calcium gluconate should be injected intravenously before injection, and symptomatic ** can also be performed, such as analgesia, sedation, and muscle spasm relief.

3 rafts of storage to destroy fat and block the Shan chicken, traditional Chinese medicine**: "The Rejuvenation of Ten Thousand Diseases" contains: "Spider bites sores, use 3 grams of realgar, a little musk, 1 5 grams of indigo, adjust the water or apply the affected area to heal immediately.

If there is no blood, there should be no problem for the body.

However, blisters indicate that the spider is venomous, and the wound can be cleaned with alcohol or hydrogen peroxide.

You try to squeeze that blister, and it won't come out.

Spiders don't die if they soak in water. When the spider falls into the water, it will soon shrink into a ball, and after seeing that there is nothing around, it will begin to grow its eight legs and swim towards the original place, and the chance of death of the spider in the water will not exceed 2%.

The hair on the spider's feet can provide a large area for the spider, and the pressure on the water will also be reduced, so the spider cannot sink, and on the spider's feet, some waxy things can also be seen, which can also prevent drowning.

Spider habits:Because spiders are highly sensitive to changes in environmental factors including habitat structure, habitat type, wind, humidity and temperature, they can be used as indicator groups to monitor habitat and biodiversity changes, and their species composition and population changes have become important indicators for environmental monitoring, which can well reflect the process of environmental change and its impact on biodiversity.

1. Generally speaking, there is no big problem, it belongs to detoxification (acid), a reaction after some spiders are frightened, and some ball spiders will also use it when hunting.

2. More serious ones will cause dermatitis (if it is not sprayed on the eyes), generally speaking, it is not a big problem to wash it off with water.

3. The ideal way is to wash it with alkaline syrup (soapy water if you don't have it) and apply some anti-inflammatory ointment.
