Venomous snakes have always been a deadly creature closest to our lives. In most people’s minds, if bitten by a poisonous snake, there is a high probability of death. Some snakes can even kill people in half an hour or a few minutes. Many people are born with an inexplicable sense of fear of poisonous snakes, even those who have never seen snakes. So how do we tell which snake is more venomous and which is relatively weak? First of all, we need to understand the types of venomous snakes. If they are classified according to family and genera, most people can’t remember. We can distinguish venomous snakes according to the type of venom. The most common types of venom are blood circulating toxins and neurotoxins. Of course there are other types. , Such as cardiotoxin, cytotoxicity and mixed toxins.
For example, most of the snakes in the Cobra family are nerve poisons. Common domestic snakes are like , silver ring snake, golden ring snake, Chinese coral snake, cobra. Viperidae is the most blood circulating poisonous snake, like five step snake, short-tailed viper, original spearhead viper, bamboo leaf green , etc., are also the most numerous venomous snakes, and their unified characteristics The head is big and the neck is thin and triangular. In addition to nerve poison, cobras usually contain another toxin, which is often referred to as a mixed toxin, like domestic Zhoushan cobra. The main symptoms after biting are ulceration and necrosis, which is also because of its nerves. The toxic content is lower, and the cytotoxic content is higher. There is also the most deadly king cobra , which is mainly cardiotoxin and neurotoxin. In addition, it is very toxic and has a large amount of detoxification, so the fatal time is very fast. Some people can even kill an adult in 5 minutes. .
To know that the most poisonous creature in the world is Australia’s " box jellyfish ",According to records, its average fatal time for wounding is 4 minutes. If the king cobra is so strong, it is second only to the world's first poison, and it is even more terrifying than tetrodotoxin and blue-ringed octopus . The lethal speed of a poisonous snake is affected by many factors, such as physical allergies and bite sites. There is a big difference between biting a toe and a tongue. The poisoning time is definitely different. There is indeed a case of a king cobra wounding a person abroad. The case of breathing stopped in about minutes, but this is only a very small number of cases, because of the physical reasons of the injured patient. Among the recorded incidents of King Cobra wounding people in China, the fastest fatal time was 30 minutes, the slowest was 4 hours, and the average fatal time was about two hours, which is not as fast as people think.
This does not mean that the king cobra is not poisonous. It is the snake with the highest fatal rate. Only a few people are bitten close to the heart or head in a short time. It's fatal, so you don't have to panic at all. Even if you are injured by the King Cobra, which has the highest fatal rate, there is plenty of time for treatment. So what should we do if we are bitten by a poisonous snake? How can we achieve reasonable self-rescue within this limited time? I believe that everyone has seen such a plot in a TV series. After the heroine was poisoned, the hero immediately sucked it out with his mouth, and then simply bandaged it and he recovered. Many people subconsciously feel this kind of treatment. The method is correct, and I used to think so.
The venom of a viper is mainly composed of protein and biological enzyme , which can only be transmitted through the blood of the human body, unlike other toxins that can be absorbed and poisoned by the stomach. Mouth sucking does not matter, but the premise is that there is no ulcer in the mouth and stomach, or bleeding gums and other symptoms. If you usually eat apples and have blood marks, doing so is a dead end. Direct oral poisoning will be better than being bitten. People are more serious.In addition, some snakes have long fangs that can penetrate the muscles, and the toxins will quickly merge with the blood. It is impossible to suck out all of them. This will put themselves in a more dangerous situation, so taking drugs is not advisable.
So is the most popular method of bandaging the proximal end useful? It stands to reason that this can delay the spread of the venom to the heart and prolong the time of the poison. It sounds reasonable, but it is not that simple. This involves the type of venom we mentioned earlier. If it is circulating toxins and cytotoxins, it is not advisable. Not only cannot be bandaged, but bracelets, rings and other items need to be taken off in time, because the symptoms of these two types of poisons are mainly Bleeding and swelling, if the blood does not circulate for a long time, it will not only not extend the time, but will accelerate the necrosis of the limbs. It may have been fine, but such a tossing is even more serious.
There are also those who use a knife to cut the wound and put poison, or use fire to roast it. It sounds very cruel and permeating. The protein is really afraid of high temperatures, but the premise is that the temperature is high enough. Furthermore, the venom has already flowed into the blood. What is the use of burning the wound? It's like a fable carve a boat for a sword, so it's also useless. Bleeding is even worse. The original bleeding can't be stopped. Once the wound is cut, the consequences can be imagined. The possibility of accelerated blood loss and shock is even greater. So what is the correct approach? We must first remember what a venomous snake looks like, which is also the most important point, because it is troublesome not knowing what kind of snake it is, and it is impossible to choose a targeted serum, which will delay the rescue time.
There are only a few venomous snakes that often hurt people in China. You can take pictures with your phone or try to remember its characteristics, whether the head is triangle or other shapes, and the patterns on the body Color and body length, etc., if you really can't remember, you can grab it and see if it is a poisonous snake. If it is a poisonous snake, you can wash the wound with clean water first.Use your hand to gently squeeze the area around the wound to expel residual venom. Don’t run and exercise vigorously. You can also find a cool place to lie down and drink plenty of water. Contact the nearby hospital for help and tell them what snake hurt you. Ask the doctor to prepare the corresponding serum.
As long as it is not a king cobra, you don’t need to be too nervous. The deadliest time of the most venomous coral snake in China is 1 hour at the fastest, 8 hours at the slowest, and many times it’s just empty Take a bite and do not inject venom, but do not go to the hospital with a fluke, so as not to delay the best time. Are you thinking what to do if it is a king cobra? I can only pray that it will not inject some venom. The king cobra bites people will definitely be poisoned, and there is no time to lie down and drink water to wait for rescue. I can only rush to the hospital quickly, if it is timely, there will still be a chance to cure.
This is not to scare people, the king cobra is the snake with the highest lethality rate in China and even in the world, up to 65%, and even black mamba can’t compare to it. The black mamba, which has a 100% fatality rate, is only the data of 7 people, and those 7 people are indeed dead, but the other patients who were bitten are not counted, and I said that all snakes except the king cobra are available. The probability of biting is 100% fatal. However, the king cobra is large and does not like to attack humans. There are very few cases of wounding. There are no more than 500 cases recorded in our country. Therefore, the probability of being bitten by it is still very small. Will get hurt.
