If you are unfortunately bitten by a snake, you should stay calm and race against time to treat the wound on the spot. The following five steps are mainly included:

1. Cauterization

Chapter To cauterize the wound immediately, you can use lighters, matches, iron wire, wooden sticks, etc. to cause the toxins to deteriorate at high temperatures. Rather cruel.

2. Ligation

After being bitten, snake venom can quickly enter the body within 3 to 5 minutes. The venous blood should be cut off as soon as possible to return to the heart. The simple way is to tie the wound with a rope, bandage or cloth strip about 3~5CM towards the heart, and relax for 1 minute after 15 minutes. In addition, you should walk slowly after an injury to slow down toxins entering the blood system. It is best to place the injured limb in a low position.

3. Rinse

If there are fangs left in the wound, the fangs should be removed and the wound should be rinsed repeatedly; within 1 to 2 hours after the injury, make a 2-3CM long cut at the wound. The cross incision is as deep as the dermis; if ice can be found in time, the ice pack should be applied to the injured limb to shrink the blood vessels and lymphatic vessels to slow down the absorption of snake venom. However, it should be noted that people bitten by blood-venomous snakes should not undergo extensive detoxification to prevent the wound from bleeding.

4. Sucking

Use your mouth to suck out the snake venom from the wound, one suck at a time Rinse your mouth with water afterward, but you should pay attention to whether the sucker has any symptoms of oral and lip ulcers

5. Ask for help

Call for help, such as 120, etc.

A combination of the above methods. In addition, you can also bring snake medicine, such as oral snakebite detoxification tablets, when outing and hiking; when camping, sprinkle realgar around the tent (actually I don’t know if it is useful, others say so).

If you are accidentally bitten by a snake, don’t panic too much. First of all, calm down and rest on the spot. Don't panic, so as not to delay the time and spread toxins throughout the body. Secondly, since snake venom can be absorbed within 3 to 5 minutes, you should immediately tie it with a tape or handkerchief 5 to 10 centimeters away from the wound, and relax for 1 to 2 minutes every 15 to 30 minutes to prevent the distal limbs from spreading. Avascular necrosis. Or squeeze around the wound with your hands to squeeze out the venom as much as possible. In an emergency, you can also use your mouth to suck out the venom as much as possible. Every time you take a mouthful, you should spit it out immediately and rinse your mouth with water. It should be noted that the mouth of the user who assists in sucking must be free of mucosal ulceration and dental caries, otherwise poisoning may occur. If possible, it is best to use ice packs or cold towels to apply cold compresses to the injured area, which can slow down the absorption of toxins and reduce the activity of enzymes in the toxins. After being rescued on the spot, the injured should be quickly sent to the hospital for continued treatment and treated with antivenom as early as possible. The injured person can drink water when he is thirsty, but do not drink alcohol to avoid accelerated blood circulation and easier spread of toxins.

Medical students will answer. If you are bitten by a snake in the wild, you must first distinguish whether it is a bite from a venomous snake or a non-venomous snake (someone commented that it is best to keep a photo of the snake, because there are different snake venom serums, of course, the premise is to ensure your own safety).

Venomous snake bites usually have one, two or three large and deep tooth marks, while non-venomous snake bites usually have four rows of small tooth marks. However, in most cases, the wound may be unclear. If it is not clear whether it is a venomous snake bite or a non-venomous snake bite, it should be treated as a venomous snake bite. ?

The best time for treatment is within 6 hours of being bitten by a venomous snake. If you are accidentally bitten by a venomous snake, you should first try to stay still in place, avoid running and strenuous exercise, and keep the wound area as clean as possible. It may be lowered and kept relatively fixed locally to slow down the absorption of snake venom and call others for rescue in time.

The next step is to tie the wound at the next joint near the heart. The binding should not be too tight, and the binding should be able to move up and down about 1cm. After bandaging, loosen it for 2-5 minutes every 15-20 minutes, and then continue bandaging to avoid ischemia and necrosis of local tissue.

The wound should be washed quickly, promptly and effectively. If conditions are limited, rinse with clean water or soapy water; if conditions permit, rinse with 2% potassium permanganate solution, hydrogen peroxide, etc. for a longer time.

At the same time, the wound can be opened or incised. If there are broken fangs in the wound, it should also be removed, which will help the discharge of snake venom. After cleaning the wound, use a knife or other sharp instrument to make an incision about 1cm long on the wound. The incision should not be too deep, just cut through the epidermis. However, if you are bitten by a viper or a five-step snake, you generally do not need to stab the person to detoxify, because they contain hemorrhagic poison and can cause bleeding. When sucking drug liquid with your mouth, you must ensure that there are no oral mucosal ulcers, dental caries and other oral diseases. It is best to use several layers of gauze.

Using drugs by mouth is not a good way, and the person sucking it may also be poisoned.

Reminder in the comment area: It is best not to try damaging wounds or taking drugs with your mouth!

Severely ill patients who become comatose after being bitten by a bungara snake or a krait can be maintained with artificial respiration.

In addition, you can also use a match head flame to instantly burn the wound, because protein is the main component of snake venom, and local high temperature can destroy part of the snake venom. As a special reminder, this method is invalid if used more than 30 minutes after being bitten by a snake.

After the initial treatment is completed, do not trust some local treatment plans. It is said that snake bites can be treated by relying on the secret recipe of ancestral snake medicine. In fact, if there is a secret recipe that can treat snake venom, the medical industry will definitely invest in its production and production. It has been vigorously promoted that many people who think they have been bitten by venomous snakes are partly bitten by non-venomous snakes. Even if they are really bitten by venomous snakes, the venom may not be very strong. Therefore, after being bitten, remember not to seek medical treatment immediately!

Sometimes Chinese herbal medicine and native methods have a certain therapeutic effect on snakebites, but in most cases, not only cannot they cure snakebites, but they can also cause side effects.

The most effective method is to inject anti-venom after being bitten by a venomous snake, and the anti-venom is most effective when used within 3 hours after the snake bite. The anti-venom is ineffective if used more than 24 hours after the snake bite. .

There are 4 types of anti-venom serum recorded in the 2005 edition of the "Chinese Pharmacopoeia": anti-viper venom serum, anti-pentapod serum, anti-bungarum serum and anti-cobra serum. They are respectively purified freeze-dried snake venom globulin preparations from the plasma obtained from horses immunized with snake venom or de-venomed snake venom, digested with gastric enzymes. For corresponding snakebite victims. Among them, the anti-viper venom serum is also effective against the bites of Trichosanthes aeruginosa and Iron-headed snakes.
