Ordinary snake bites leave only small tooth marks on the skin of human wounds, mild tingling, and some can cause small water scars without systemic reactions. Can be sterilized with 70% alcohol, plus gauze bandaging, generally no adverse consequences. Snake bites can leave a pair of deeper tooth marks on the wound. The inherent snake venom enters the tissue, and enters the lymph and bloodstream, which can cause severe poisoning. Must be treated first aid.
Snake bite snake bite symptoms and signs
- Ordinary snake bites leave only small tooth marks on the skin of human wounds, mild tingling, and some can cause small water scars without systemic reactions. A snake bite can leave a pair of deeper tooth marks on the wound.
- There are two rows of deep coarse tooth marks on the part, which have bleeding, pain, redness and swelling, and spread to the proximal end of the body. Nearby lymph nodes are swollen, tender, and blistered.

- Snake bite
- Neurotoxicity, numb the wound first, and spread to the proximal side causing dizziness, blurred vision, drooping eyesight, unclear speech, limb paralysis, dysphagia, and dyspnea; finally, it can lead to respiratory failure.
- Blood circulation poisoning can make the wound swollen and painful, and spread to the near heart side, and nearby lymph nodes also have swelling and pain; and cause chills and fever, heart rate and arrhythmia, restlessness or delirium, as well as skin purple spots, hematuria and oliguria , Yellow dye, etc .: in the end can lead to heart, kidney, brain failure.
- Mixed poisons have the effects of both neurotoxicity and blood circulation poisoning, but mixed poisons such as cobra and viper have different effects on nerves and blood circulation.
First aid measures for snake bite
- 1.Prevent the spread and absorption of venom
- After being bitten by a poisonous snake, don't panic and run around. This will cause the venom to spread quickly throughout the body. The injured person should immediately sit or lie down, or call for help by himself or herself, and fastly bind the proximal end of the wound with a rope such as laces or trousers that can be found. If the finger is bitten, the root of the finger can be tied; palm or A bite on the forearm can be banded on the elbow joint; a bite on the toe can be banded on the root of the toe; a bite on the foot or calf can be banded on the knee joint; a bite on the thigh can be banded on the root of the thigh. The purpose of bandaging is to block the return of venom into the heart through veins and lymph, without impeding the supply of arterial blood, which is different from the purpose of hemostasis. Therefore, the banding does not need to be too tight, and its tightness is controlled by being able to slightly weaken the arterial pulsation of the banded lower limb. After bandaging, loosen it every 30 minutes or so, 1-2 minutes each time, so as not to affect the blood circulation and cause tissue necrosis.
- Quickly eliminate venom
- Immediately wash the wound and surrounding skin with cold water, spring water, soapy water or 1: 5000 potassium phosphate solution to wash away the venom on the surface of the wound. If toxic teeth remain in the wound, it should be quickly picked out with a sharp knife or other sharp objects such as broken glass. It is best to use fire to disinfect it before use. Make a cross incision with the tooth mark as the center, deep down to the skin, and then repeatedly squeeze from the proximal end of the limb to the direction of the wound and around the wound with your hand to promote the venom to escape from the cut wound and rinse with water while squeezing Wounds, irrigation and detoxification should last for 20-30 minutes. After that, if you carry a tea cup with you, you can cup the wound. First, light a small piece of paper in the tea cup, and then fasten the mouth of the cup to the wound, so that the mouth of the cup is close to the skin around the wound. venom. If there is no tea cup, you can also use the mouth to suck wounds to detoxify, but the mouth and lips of the sucker must be free of damage and caries, otherwise there is a danger of poisoning. Suck out the venom immediately, and rinse with water after inhalation.
- After detoxification is complete, the wound should be wet-dried with venom to flow out. It must be noted that snake venom is highly toxic and can be fatal with only a small amount, so you must not refuse to open the wound for detoxification because of fear of pain. If you have snake medicine with you, you can take it orally to detoxify. Patients with thirst may drink plenty of water. Never give alcoholic beverages to accelerate the spread of toxins. The wounded after incision and detoxification should be taken to a hospital with a stretcher or a vehicle as soon as possible. After arriving at the medical unit, first wash the wound with 0.05% potassium permanganate solution or 3% hydrogen peroxide; The deeper person cuts the dermis layer slightly, or punctures the skin layer with a triangular needle in the swelling area, and then sucks it with a cupping method or a breast pump to promote the discharge of part of the venom. Add 6000U to 10-20ml of 0.05% procaine or water for injection to seal the periphery or proximal side of the wound, and it can be repeated at intervals of 12-24 hours. In order to avoid serious situations that cannot be handled in the wild. During the transfer, the patient's nervousness should be eliminated and keep quiet.

- 2. Rinse the wound repeatedly with well water, spring water, tea water, tap water, or 1: 5000 potassium permanganate solution, while making multiple "ten" incisions on the wound to detoxify. Then use a hot pot, breast pump, suction device to suck out the poisonous juice. In an emergency, suck the poisonous juice out of the wound with your mouth, and the rescuer will spit out immediately after sucking, and clean the mouth.

Snake bite related information
- Snake venom contains many substances such as enzymes or proteins, the content of which varies depending on the type of snake. These substances can invade the blood, nervous system, or other tissues. Some snake venoms have a direct toxic effect, but they are not all fatal to humans. Some have systemic lethal toxicity (such as rattlesnake's venom), while others initially only damage tissues near the wound, but can cause gangrene.
- If the bite is in the extremities, immediately fix the injured limb in a horizontal position, and then wrap the wound with a wide, solid bandage or wrap the entire limb; splints can be used as an aid. Amputations, sucking wounds, or using arterial tourniquets are unwise. Force and excitement should be avoided to prevent an increase in the pulse rate that leads to faster circulation. Similarly, stimulants should be avoided. Drugs such as potassium permanganate are also harmful to the wound.
- Most types of snake venom poisoning can be cured with anti-venom serum. The effectiveness of anti-venom serum prepared from immunized animals (especially horses) depends on the specificity of the anti-venom serum, the content of antibodies, and the concentration and purity of the preparation. Although certain snake snake bites are better treated with specific anti-venom sera, some anti-venom sera can treat a variety of related snake venoms. For example, the snake venom of Notechis scutatus is the same for several other snake venoms. Also effective.
