What should I do if I am bitten by a venomous snake outdoors?

Rodent snake bites, generally no big problem, because this kind of snake is non-venomous, there are small holes in the bite of poisonous snakes, because poisonous snakes, especially highly venomous snakes, have sharp and long teeth, venom enters the human body through the channels of teeth, the venom of the krait snake is paralyzing, and there is only a paralyzing feeling at the bite, **Jue, there is no cure after half an hour, and the bite of Zhu Yeqing, the wound is as hot as a coal. Venomous snakes can be divided into blood venom, nerve venom and compound venom contained in both, the silver krait snake is nerve venom, and the belly snake is compound venom. If you are bitten by a poisonous snake, don't run in a hurry, you should treat the wound on the spot, such as rinsing with plenty of water, burning the wound with a lighter, if there is a knife, cutting the wound for detoxification, cross cutting, and tying up a tourniquet at the proximal end of the wound to avoid venom flowing back into the heart, lungs and liver with the blood.

Symptoms generally appear gradually between 10-20 minutes after being bitten, if there is no local pain, swelling, numbness and weakness within 20 minutes, it can be judged as a non-venomous snake bite, at this time, only need to disinfect, stop bleeding, bandage and then send to the doctor for tetanus or anti-inflammatory injection.

If it is uncertain whether it is a venomous snakebite, it is still necessary to treat it according to the first aid method for venomous snakebites. The main purpose of treating a venomous snake bite is to stop the venom from spreading further into the body, calm and relax, and keep the wound lower than the heart. Then, make a cross-shaped incision along the snake tooth marks for rinsing and detoxification, and the effect will be better if soap can be used.

Secondly, a bandage should be tied 5-10 cm above the wound to stop the venom from running through the body, but not too tightly, leaving one finger space, the bandage should be relaxed every 20 minutes for 30 seconds each time, and it is best to tie another one above the bandage. Try to slow down the movement of the injured person, send them to the hospital quickly, and describe the type of snake to the doctor so that the right medicine can be used.

After being bitten by a venomous snake, emergency treatment:

1. After being bitten by a venomous snake, you should be calm, reduce your activities as much as possible, and deal with it on the spot.

2. Immediately tie the proximal end of the venomous snakebite limb (i.e., the end close to the heart) about 5 cm with a cloth belt or tourniquet to reduce the absorption and diffusion of toxins. The sooner the ligation, the better, the tightness of the binding is to block the lymphatic or venous return (does not affect the arterial blood**), and the binding is released in time after the local wound has been properly treated, so as to avoid circulatory disorders.

3. Rinse the wound: according to local conditions, you can choose spring water, water, cold boiled water, or even rinse the wound repeatedly with your own solution, rinse the adherent venom, reduce the absorption of toxins, and eliminate snake venom as soon as possible.

4. After finding and extracting its fangs, you can use a clean sharp, porcelain or glass to cut the wound or make a cross-shaped incision with the viper's tooth marks as the center, deep under the skin, and then squeeze. Detoxification methods such as cupping and negative pressure suction can also be used.

5. Timely delivery to the hospital: under aseptic operation, use 2000 units of crystalline trypsin plus 5 10 ml of procaine for local infiltration injection, and make a ring closure at the proximal end of the wound. The potassium permanganate solution soaks the affected limb to oxidize part of the snake venom absorbed by the affected limb and inactivate the snake venom.

Early application of antivenom**: Intravenous infusion of antivenom is best for different snake bites, but it must be done under the supervision of a physician to avoid allergies and accidents. At present, there is no drug in the ** drug of snake bite that is more effective than antivenom.

After being bitten by a venomous snake in the wild, the first thing is to stay calm. After being bitten by a venomous snake, the speed of first aid is calculated in minutes and seconds, the sooner the better, the faster the better, you must keep calm in order to save yourself in an orderly manner. Remember not to run fast, as the blood circulation will speed up, and the speed at which the snake venom will enter the body through the blood circulation will be accelerated.

Second, pull out the fangs. Poisonous snakes bite people usually out of self-defense and fight back. As soon as a person steps on a snake, the snake's counterattack is a dying struggle, so it will bite very hard.

Shake off the poisonous snake, and the fangs will often break inside the wound. The venom in the fangs is extracted as quickly as possible for further first aid to avoid causing more venom to invade the human body. Secondly, the fire.

The fire does not need to scorch the wound, only the wound needs to be blistered. The heads of the matches are circled towards the wound, and the matches are detonated with lit matches. A deflagration of a match is enough to destroy local snake venom.

Ligation. The sooner the ligation is done, the better, using a rope or by tearing clothing into strips of cloth for the wound and the ligation site. Ligation is the extent that arterial blood can pass through the vein and cannot flow back.

The ligation should not be too tight and too long. Many snake wound patients have limb necrosis and are eventually forced to amputate, mostly because the limb ischemia is caused by a long transit time after ligation. Washing.

Place the wound under running clean water and rub the wound with your hands under the water to wash away the venom that adheres to the wound. Toxins are removed before they enter the body. These are all ways to save yourself from being bitten by a poisonous snake.

1. In daily life, if people are unfortunately bitten by poisonous snakes, then they should find a place with water as soon as possible, put the amount of water to the maximum, and rinse the wound repeatedly, so as to dilute the venom components in the wound. Usually, the venom will stay in the wound immediately after being bitten by a venomous snake, and rinsing with water can slowly expel some of the venom, but be sure to rinse it with running water.

2. After rinsing the wound, people should tie their arms or thighs not far from the wound with a strap, which can slow down the blood circulation of the body and prevent the rapid spread of venom, but it must not be tied too tightly.

3. After people are bitten by poisonous snakes, in addition to treating their own wounds, they should also call the hospital for help as soon as possible, and at the same time do not walk too fast or run fast, which will accelerate the spread of venom, and should be slow.

4. The venom spit out by the poisonous snake will destroy the hemoglobin in the human blood, so that people will have physical failure, therefore, after being bitten by the poisonous snake, people should eat more foods containing high protein, such as: raw eggs, milk, etc., which is very beneficial to the recovery of the body.

After being bitten by a venomous snake, the venom of the poisonous snake's mouth directly enters the human body, resulting in damage to human organs. After being bitten by a venomous snake, the most important thing is to prevent venom from entering the human circulation, so the first treatment after a venomous snake bite is ligation, which can be tied with a tourniquet at the proximal end of the bite to avoid blood flow or reduce the flow of blood to the human body, and then block the local blood flow to prevent the venom from entering the human body.

If you are bitten by a poisonous snake, if the fangs are in the body, the fangs should be extracted. If the wound caused by a venomous snake bite is large, local debridement should be performed, and tetanus injections should be given to prevent tetanus bacterial infection. The core treatment of venomous snakebite is to use anti-venomous snake serum**, and different antitoxin serums are used for different snakes, so venomous snakebite is a comprehensive situation, mainly including the following measures:

1. The proximal end of the biting limb should be ligated to reduce blood flow or reduce the diffusion of toxins into the human body;

2. Perform local debridement**;

3. According to different species of poisonous snakes, different antitoxin serums should be used, if you are bitten by poisonous snakes, try to pat the poisonous snake as much as possible to help doctors use different anti-poisonous snake serums.
