How to give first aid if bitten by a poisonous snake

1. Stay away from dangerous places

After being bitten by a snake, you need to stay away from the place where you were bitten immediately. If the snake bites the body and does not let go, you can Use a stick or other tool to pull it apart. After being accidentally bitten by a snake in the water, the patient needs to be moved to the shore immediately to avoid drowning. Afterwards, you need to remember the characteristics of the snake. If conditions permit, you can also take pictures with your mobile phone, which will help the doctor make better judgments.

2. Don’t be anxious

Once bitten by a venomous snake, you must first have a peaceful mind and don’t be afraid of being anxious. Many patients who are bitten by non-venomous snakes are overly nervous. leading to the occurrence of shock. Maintaining a peaceful mind is very important in the treatment of poisonous snake bites, because snake venom will spread with accelerated blood circulation, and emotional stress will cause blood to rise and blood circulation to accelerate. In this way, symptoms of poisoning will also appear early. Also, the most taboo thing after being bitten by a poisonous snake is to run. You should stay quiet while waiting for rescue.

3. Relieve pressure

After being bitten, you need to immediately remove the pressure items from the injured area, including rings, bracelets, anklets, watches, clothing, etc., to avoid subsequent swelling. The situation makes it impossible to remove these items, thereby aggravating the local swelling. During this period, you must try to stay calm and don't panic too much, which can effectively reduce the body's absorption of toxins.

4. Bandage to stop bleeding

After that, you need to immediately use a tourniquet to tie it tightly about 5 to 10 centimeters above the wound, which can reduce the absorption and spread of toxins. Relax for 1-2 minutes every 20 minutes to avoid limb ischemia and necrosis. You can use a wide strip of cloth for the tourniquet. Do not use a rope. If it is too thin, it will block the blood circulation and cause the risk of necrosis of the lower limbs. It is better to tie it with a strip of cloth that is at least one centimeter wide. It should not be too tight. One finger can do it. It's best to tuck it in.

5. Wash the wound

The wound can be washed repeatedly with clean water to remove the venom adhering to the skin surface. Potassium permanganate or peroxide can also be used if conditions permit. Flush the wound with hydrogen solution. If there are still fangs in the wound, they should be removed immediately. After taking basic treatment measures, you need to send the patient to a doctor immediately for treatment.

Can you use your mouth to take drugs after being bitten by a poisonous snake?

Sucking out the venom with your mouth may not only fail to save the bitten person, but may also poison the rescuer! Especially if the rescuer's oral mucosa is damaged, toxins can enter the body through the damaged mucosa, causing acute poisoning immediately.

Wrong ways to deal with snake bites

1. Let the injured person run around

Many people have been bitten by snakes. When they become nervous, the people next to them also become nervous. I was so panicked that I ran around looking for hospitals and remedies, because the spread of snake venom in the body occurs through blood circulation, and the speed of blood circulation is closely related to the movement of the limbs. If you exercise strenuously, it will promote the spread of toxins in the body.

2. Squeeze the wound casually

The wound is just a little bit bigger, and it is impossible to squeeze out the snake venom and squeeze it clean. If the squeezing is not done properly, it may aggravate the spread of venom!

3. Cut the wound with a knife and bleed it

Anyway, this method of poking and poking is not only ineffective in detoxification, but may also increase the wound area and make it susceptible to infection, making it difficult to heal the wound later. Even severe blood loss (some people do it lightly) is life-threatening!

4. Burning with fire

This method of self-mutilation has poor operability and poor effect. Moreover, the severe pain caused by burning will stimulate and accelerate blood circulation, causing the wound to not heal or even become necrotic.

5. Drinking alcohol "disinfects" and strengthens courage

Drinking alcohol not only fails to strengthen courage, but will speed up blood circulation and accelerate the absorption of toxins.

6. Tighten it with a tourniquet

The first thing most people think of after being bitten by a snake is to use a tourniquet to close the bite proximal to the heart. The purpose of tightly binding is to prevent toxins from flowing back with the blood and slow down the absorption of toxins. Because the tourniquet is elastic, the tightness cannot be judged. Long-term ligation can easily lead to interruption of arterial blood supply and limb necrosis due to ischemia. When tying the rope, remember to leave a thumb free. This can prevent superficial venous and lymphatic return but does not hinder arterial blood flow! Don't tie it too tightly, or you may strangle the blood vessels.

7. Indiscriminate application of herbal medicines

There have always been some wonderful herbal remedies in the world. Anyway, legend has it that everything can be cured, and snake bites are no exception. It is said that grinding these herbs into dregs and applying them to wounds can reduce swelling, relieve pain, and calm down. Most people do not recognize the so-called detoxifying herbs, and the herbs in the wild have not been disinfected. Nine out of ten wounds of patients who apply herbal medicines are secondary infected.
