I Have a Safari Park

(One chapter is all about the science of snake bites. Will you be bored with science? If you are bored, just skip it. However, it is recommended to read it. The skill of slapping tigers is not used. This is in case it comes in handy)

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

Fang Ye smiled and thought about what to say: "I don't know if you have heard a news from a few years ago, saying that a girl was walking on the roadside, her phone fell into the grass, and she was caught by a snake when she lowered her head to pick it up. Bitten. After being bitten by a snake, I just grabbed it and took it to the hospital."

Dawu immediately became excited: "Oh, I've seen this news! It's so domineering!"

A tourist admired: "I have seen it too! I remember that the girl was holding a snake with one hand and filling in the case with the other. She was very calm! So I was very impressed. But later I found out that it seemed to be a non-venomous snake."

A tourist asked curiously: "Is this method the correct operation? After being bitten by a snake, grab it, otherwise it seems that the serum cannot be made. The serum required by each poisonous snake seems to be different."

Lin Hao frowned slightly and muttered in his heart, "Is that so, it always feels weird?"

Fang Ye smiled and said: "After being bitten by a snake, the emergency treatment method is very important, and there are indeed many misunderstandings in this regard.

The girl in the news is very powerful, catching snakes with her bare hands, but this is a wrong demonstration. Fortunately, she encountered a non-venomous snake. If it is a poisonous snake, the danger will be great.

Catching snakes requires professional equipment and skills!

Don't learn to catch the snake with her bare hands, otherwise, the poisonous snake may have just given a simple bite as a warning, without releasing the venom, and nothing happened. The catch angered the poisonous snake and was bitten again. This time, it was injected with poison, or even more Large doses, how to say?

In the process of catching snakes and transporting them, secondary injuries may be caused.

Different serums are used to be bitten by different types of venomous snakes, but they are not made from existing snakes! It's all made early. "

The flat-headed boy said, "I see. If you don't catch the snake, you should take a picture as soon as possible, so as to help the doctor identify which kind of poisonous snake it is, right?"

Fang Ye said: "It depends on the situation. If you happen to be using a mobile phone or a camera, you can take a picture and forget it.

After a poisonous snake defensively bites, it will not stay still, but will leave quickly. When you take out your mobile phone, access the camera software, and adjust the shooting angle, the poisonous snake has already run away. Can you take a picture by digging into the grass? Can't you chase after the snake?

Feeling anxious and exercising can increase blood flow, accelerate the spread of toxins, and delay first aid.

After being bitten, it is best to calm down and first judge whether it was bitten by a poisonous snake. You can look at the tooth marks of the snake bite.

The tooth marks of non-venomous snakes are serrated, and the tooth marks are small and shallow. When bitten by venomous snakes, there are generally 1-4 large, deep and obvious venomous tooth marks.

Tooth marks are purplish-black, and nearby skin is purplish-purple swollen or numb.

If it is a venomous snake, take first aid measures, and then try to minimize exercise and wait for rescue.

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

The big brother with the national character face wisely said: "Bite your finger and cut it off!"

"Haha." Fang Ye didn't know whether to laugh or cry, "Brother, you are a bit ruthless, so what about the bite?"

Guozilian thought for a while and said, "Then don't cut it, let's suck it out. I know this, as long as there is no bleeding from the mouth."

Dawu said: "I remember seeing this kind of news! Someone was bitten by a snake when they went up the mountain to chop wood, so they cut off their fingers with a hatchet."

A tourist beside him nodded in agreement: "Abandon the car and protect the handsome, as long as you can survive!"

Now everyone still thinks "strong man breaking his wrist" is a normal emergency response method.

Fang Ye couldn't help sighing, and felt more and more the importance of popularizing knowledge about how to deal with poisonous snake bites.

"It is absolutely wrong to cut it directly. In case of a non-venomous snake, cutting off its limbs may lead to severe blood loss shock or even death, and it will be permanently disabled in the future. It is not blood loss.

In 1994, a child in a village in Zhejiang was bitten by a five-step snake while catching a frog. In order to save the child's life, his father quickly chopped off his son's arm with a hatchet. The snake venom is gone, but a lively and lovely child has lost his arm forever. "

The tourists all showed their shocked expressions, and one by one sucked in the cold air: "Hi~"

"Wow, this kid is so miserable."

Fang Ye said: "The five-step snake just describes this snake as being extremely poisonous, it doesn't mean that after biting it, it really takes five steps to die!

This practice is equivalent to giving the baby a bath in the basin and pouring out the baby with the dirty water.

If you are bitten by a poisonous snake, take off your jewelry first, because after being bitten by a poisonous snake, the bitten part will swell up quickly, and the blood will not circulate if you wear rings and bracelets. To be amputated.

Then use the belts, headphone cables, rubber bands, shoelaces and other things that we often carry with us to make a binding ligation. The sooner the ligation is done, the better! It can stop the spread of snake venom in time.

The location is 5-10 cm from the proximal end of the wound, and it is pierced at the base of the finger when it is bitten on the finger. It is important to grasp the tightness of the ligation, and do not tie it too tightly. Just like drawing blood, a finger can be inserted.

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

Then rinse the wound repeatedly with clean water, soapy water, saline or potassium permanganate solution, the effect is better.

Just now, my eldest brother said that you use your mouth to suck. The mouth sucks can play a certain role when you are just bitten. It is useless after spreading and sucking, because snake venom is chemically combined, and physical methods cannot be completely discharged.

And be careful not to have gum bleeding or something, and every time you suck out and spit out the snake venom, you should rinse your mouth to clean your mouth, because the sublingual veins are rich and absorbable, otherwise you may be poisoned twice.

There is no need to worry if a small amount of snake venom is swallowed into the stomach by mistake, because the snake venom will be decomposed by gastric acid after entering the stomach, and no poisoning will occur. Except for stomach disease.

Let's talk about expansion and detoxification.

Both of these methods are effective, but ordinary people should not use them, and only professionals are recommended to use them.

The principle of wound expansion is the same as mouth suction detoxification. However, it is difficult for ordinary people to grasp how long and how deep the cutting is. Shallow cutting has no effect, and deep cutting is not conducive to recovery. Moreover, some snake venoms are blood poison, venom There are anticoagulant substances in the wound, which will cause blood to flow out continuously, aggravating the injury.

The principle of fire detoxification, because the composition of snake venom is protein, and fire can make the protein denatured and inactive.

Some snakes have long fangs and deep venom injection. Fire can only burn to the surface layer, and cannot destroy the venom in the depths at all.

However, for some venomous snakes with shallow fangs and a small amount of venom, the method of burning has a miraculous effect. Generally, a few match heads are placed on the wound and ignited, and the venom is destroyed by the high temperature of instant burning.

However, if ordinary people use it, it is very likely that they will not master it well, causing skin tissue burns and infection, and will not be able to destroy the snake venom, so it is best to only use the previous methods!

Just like the roundhouse kick of the blind man in the League of Legends, professional players use it steadily and accurately, and one kick determines the battle situation, and the bronze blind man may touch his eyes and give it away.

After the emergency treatment is over, go to the hospital as soon as possible! "

After a long series of words, Fang Ye took a breath, and the tourists applauded admiringly: "I learned it, I learned it!"

"Thank you, principal, for correcting a lot of misunderstandings I knew!"
