Chapter 277

(one chapter is all about poisonous snakes biting popular science. Is it boring to join popular science? If it's boring, just jump, but it's still recommended to take a look. The skill of rolling tigers can't be used. What if it can be used)

Lily said, "how do you deal with being bitten by a snake?"

Fang Ye smiled and thought about how to say: "I don't know if you've heard a news a few years ago that a girl was walking along the road. Her mobile phone fell out of the grass and was bitten by a snake when she lowered her head to pick it up. After being bitten by a snake, he caught it directly and took it to the hospital. "

Dawo was immediately excited: "Oh, I've seen this news! How domineering! "

A tourist admires: "I've seen it too! I remember the girl holding the snake in one hand and filling the case in the other. She was very calm! So I was impressed. But it looks like a non poisonous snake. "

A tourist asked curiously, "is this the correct operation? After being bitten by a snake, catch it, otherwise it seems that you can't make serum. It seems that each kind of poisonous snake needs different serum. "

Lin Hao frowned slightly and muttered in his heart, "is that right? It always feels strange?"

Fang ye said with a smile: "after being bitten by a snake, the emergency treatment method is very important. There are many misunderstandings in this regard.

The girl in the news is very powerful and catches snakes with her bare hands, but this is a wrong demonstration. Fortunately, she met a non poisonous snake. If it was a poisonous snake, it would be very dangerous.

Catching snakes requires professional equipment and skills!

Don't learn from her to catch a snake with her bare hands. Otherwise, the snake may have simply bitten as a warning. It didn't release the venom. Nothing happened. Once it was caught, it angered the snake and was bitten again. This time, it was injected with poison, or a larger dose of poison. What do you say?

Secondary injury may be caused during snake catching and transportation.

Being bitten by different kinds of poisonous snakes requires different serum, but it is not made by current snakes! It was done early. "

The flat headed boy said, "I see. If you don't catch a snake, you should take a picture at the first time to help the doctor distinguish what kind of poisonous snake it is, right?"

Fang ye said, "let's divide the situation. If you happen to use it on your mobile phone or camera, you can take a picture easily. Forget it.

After the defensive bite, the snake will not stay in place, but will leave quickly. When you take out your mobile phone, access the camera software and adjust the shooting angle, the snake has already run away. Can you take a picture when you drill into the grass? Still chasing snakes?

Panic and exercise will speed up blood flow, accelerate the spread of toxins and delay the time of first aid.

After being bitten, you'd better calm down and judge whether you were bitten by a poisonous snake. You can see the tooth marks of the snake.

The tooth marks of non-toxic snakes are serrated, and the tooth marks are small and shallow. When bitten by poisonous snakes, there are generally 1-4 large and deep, very obvious tooth marks! The tooth marks are purplish black, and the nearby skin is purplish blue, swollen or numb.

If it's a poisonous snake, take first aid measures, and then try to reduce exercise and wait for rescue!

You should also know some first aid measures after snake bite? "

"Bite on your finger and cut off your finger directly!" said brother guozilian tactfully

"Ha ha." Fang Ye couldn't cry and laugh properly. "Brother, you're a little cruel. What about biting your hand?"

The national character face thought and said, "then don't cut it. Suck it out. I know this. It's only if there's no bleeding in the mouth. "

Dawo said, "I remember seeing this kind of news! Someone was bitten by a snake when he went up the mountain to cut firewood. He took a firewood knife and cut off his fingers. "

Next to the tourists agreed and nodded: "abandon the car to protect the handsome, as long as you can survive!"

Now we still feel that "a strong man breaks his wrist" is a normal emergency treatment method!

Fang Ye couldn't help sighing and felt more and more that it was important to do a good job in the science popularization of snake bite treatment knowledge.

"It's absolutely wrong to cut directly. If it's a non-toxic snake, cutting off the limbs may lead to serious blood loss shock or even death, and you'll be disabled forever. That's not blood loss.

In 1994, a child in a village in Zhejiang was bitten by a five legged snake while catching frogs. In order to save his child's life, his father quickly cut off his son's arm with a firewood knife. Snake venom is gone, but a lively and lovely child has lost his arm forever. "

The tourists showed a shocked look and sucked the air conditioner one by one: "hiss ~"

"Wow, how miserable the child is."

Fang ye said, "the five step snake just describes that the snake is very poisonous. It doesn't mean that it will die if it takes five steps after biting!

This method is equivalent to what, give the baby a bath in the washbasin, and pour out the baby when pouring out the dirty water.

If you are bitten by a poisonous snake, take off the jewelry on your hand first, because after being bitten by a poisonous snake, the bitten part will soon swell up, you can't take it off wearing a ring and bracelet, and the blood can't circulate. After a long time, you may have to amputate your limbs.

Then we take what we often take with us, such as belts, earphone wires, rubber bands, shoelaces and so on, to make a binding and ligation. The faster the ligation, the better! It can block the spread of snake venom in time.

It is located 5-10cm near the proximal end of the wound. Bite on the finger and tie it at the root of the finger. It should be noted that the tightness of ligation should be well controlled. Don't tie it too tightly. Just like drawing blood at ordinary times, you can put a finger in it.

Tie it for 40 minutes, 1 hour and loosen it for 10 minutes. Otherwise, if the tie is too tight for too long, the distal hypoxia and necrosis may occur.

Then rinse the wound repeatedly with clean water! Soapy water, salt water or potassium permanganate solution, the effect is better.

Just now, big brother said to suck by mouth. Mouth suction can play a certain role when it is just bitten. It is useless to suck again after diffusion, because snake venom is a chemical combination and cannot be completely discharged in a physical way.

And pay attention not to have gum bleeding or anything, and rinse your mouth and clean your mouth every time you inhale and spit out snake venom, because sublingual veins are rich in blood vessels and strong absorption, otherwise you may be poisoned again.

Don't worry about swallowing a small amount of snake venom into the stomach by mistake, because the snake venom will be decomposed by gastric acid and will not be poisoned. Except for stomach diseases.

Besides expansion and fire detoxification!

Both methods are effective, but ordinary people don't use them. Only professionals are recommended to use them.

The principle of wound expansion is the same as that of oral inhalation detoxification, but it is difficult for ordinary people to master how long and how deep the wound expansion is cut. If it is shallow, it will have no effect, and if it is deep, it will not be conducive to recovery. Moreover, some snake venoms are blood venom, and there are anticoagulant substances in the venom. Cutting the wound will make the blood flow out continuously and aggravate the injury.

The principle of fire detoxification, because the component of snake venom is protein, fire can denature the protein and lose its activity.

Some snakes have long teeth and deep poison injection. Fire can only burn to the surface and can't destroy the venom in the depths.

However, for some venomous snakes with shallow fangs and small amount of poison, the method of fire is very effective. Generally, several match heads are placed on the wound to ignite, and the snake venom is destroyed by the high temperature of instant burning.

However, if ordinary people use it, they may not master it well, cause skin tissue burns and infection, and can't destroy snake venom, so it's best to use only the previous methods!

Like the whirl kick of the blind in the hero League, the professional players use it firmly, accurately and ruthlessly to determine the war situation. The bronze blind may touch their eyes and give it away directly.

After emergency treatment, go to the hospital quickly! "

After a long string of words, Fang ye took a breath. The tourists clapped their hands in admiration: "learned, learned!"

"Thank you for correcting many misunderstandings I know!"
