385 bitten by a snake

The group moved forward carefully.

With Su Yang's way, everyone's actions have indeed been much faster and much smoother. Just like Su Yang's body is carrying a snake-driven halo, all the poisonous snakes will give in automatically when they see him. After a long journey, they did not see the dense snakes again. They only occasionally dodge a few, and they all dodge far away. It's very magical.

At around 3 pm, everyone came to a place.

Shi Qinghai looked at it, breathed a sigh of relief, and said on the walkie-talkie: "Everyone rest on the spot for ten minutes."

At this time, everyone seemed to have walked out of the snake's nest, and there was almost no feeling of uneasiness, and many people breathed a sigh of relief.

So everyone found a place to sit down. Except for the people who continued to watch, everyone took out water and dry food to eat, resting and replenishing their physical fitness.

This long journey last night was not sleeping all night. To be honest, it was really a bit tiring.

Su Yang had finished eating a single soldier food when he suddenly heard someone there roaring. Soon, the radio rang: "Scalpel, I was bitten by a snake!"

When Su Yang heard this, he stood up with a whoosh, grabbed the backpack on the ground and rushed towards the place where the sound came from.

Whoosh-

It was like a tiger descending the mountain, with an incredible speed.

And the most terrifying thing is that I perfectly avoided all the treetops and roadblocks on the road, just like playing parkour.

The people who were eating were all stunned.

Although they have been teaming up with Su Yang for most of the day, they don’t know much about Su Yang. Apart from knowing that he rescued Guo Jia, who has lost his breathing and heartbeat, they don’t know anything else. Of course, Shi Qinghai once repeatedly emphasized to everyone that Su Yang’s medical skills are very good, especially in battlefield first aid, and he is even more of a master, but no one has any special feelings. However, everyone still thinks, well, Su Yang’s medical skills should still be good.

But everyone just thinks that Su Yang is just a military doctor with extraordinary medical skills.

Just now, along the way, everyone gradually realized that Su Yang's physical fitness was really good. He had been walking for such a long time, and he also carried the heaviest military backpack among everyone, but he still had no blushing or breathing, and his physical fitness was even better than the best one among the team members.

When everyone saw this, they were secretly surprised. Damn, this military doctor has good endurance!

But now, with a whoosh, Su Yang disappeared from everyone's noses and rushed to the distance in the blink of an eye. This speed—

The fastest guy on the team is not as good as that?

Is this guy a front-line combatant or a military doctor?

Is the endurance and speed of the military doctor so strong?

The group was stunned.

The other side.

Su Yang had already rushed to the team member who was bitten by a poisonous snake.

This team member was also unlucky. He had just finished the self-heating individual soldiers' food and was about to start eating. He felt a little uncomfortable in his stomach, so he walked away and found a place to solve his personal problems.

He was very careful when he squatted down. Because the experience just now made him not careless, but nothing happened. So when he stood up, he became a little careless. Just as he was about to turn around and walk back, he found a branch blocking his way. He bent down and looked down just now, but now, he instinctively pushed it with his hands. Unexpectedly, there was a snake on the branch, which was disguised as a piece of dry branch. When the snake saw someone moving him, it bit the guy's arm.

The soldier just heard Su Yang's words, so he immediately called by radio.

As soon as he finished speaking, Su Yang rushed in front of him!

"Which snake bites you?" Su Yang asked the first sentence.

"There! That one!"

Su Yang hurried to see.

The first thing to do when bitten by a snake is to tell whether the other party is a venomous snake or a non-venomous snake, which is very important.

After the human body is bitten by a venomous snake, its venom enters the human body through the wound, which will cause acute systemic poisoning. Its onset is fast, its clinical manifestations are diverse, and there are many complications. In addition to local symptoms, it can also cause damage to the functions of a variety of organs, and in severe cases it can endanger life.

So, you should not be careless when bitten by a snake. The first thing to do is to find out whether it is poisonous or not.

There are many folk sayings about whether snakes are poisonous or not. Some of these statements are vicious snakes, some of which are triangular, but most of them are inaccurate.

Epidemiological investigations of snake bites believe that the heads of poisonous snakes are mostly triangular, with thin necks, short and thick tails, bright spots, and longer teeth.

Two rows of deep and thick tooth marks are often left on the bite of the poisonous snake.

There are more than 160 Chinese snake species, including about 50 viper species, with more than 10 species, such as cobra, golden ring snake, cobra, five-step snake, silver ring snake, viper, viper, viper, bamboo leaf green, iron head, sea snake, etc., which often endanger human life after biting.

These poisonous snakes often appear in forests, mountainous areas and grasslands in the south in summer and autumn. Among them, snake bites in coastal areas of Zhejiang and Jiang have their own unique epidemiological characteristics. The common types of poisonous snakes are vipers, cobras, five-step snakes, etc., and summer and autumn are the high-incidence seasons.

Su Yang glanced at the poisonous snake that the team member mentioned, and then he took a step forward.

Whoosh!

His hands grabbed them like lightning.

With just a moment, he grabbed the poisonous snake that was entrenched on the treetops.

He pinched the snake's head and observed it, especially his teeth.

It's a poisonous snake, and it's a very venomous one.

The pathogenesis of venomous snake bites is related to the type of snake venom and the location of the patient's bite.

The clinical manifestations caused by different types of snake venom are different. Snake venom contains toxic proteins, peptides and enzymes, which can be summarized into three categories according to their effects on the human body.

1. Nerve poison. After a snake bite with nerve poison, local manifestations are numbness in the wound, pain is not obvious, and no obvious seepage, but it gradually spreads to the proximal end, which can cause dizziness, nausea, vomiting, blurred vision, sagging eyelids, unclear language, limb paralysis, difficulty opening and swallowing, tight teeth, which can lead to damage to the respiratory muscles and difficulty in breathing, and finally lead to respiratory failure.

Another type is blood circulation toxicity: This type of snake venom is complex, including hemorrhagic toxicity, coagulation toxin and anticoagulant toxin, which has many toxic effects and mainly involves the cardiovascular system and blood system.

Blood circulation poison mainly exists in five-step snakes, bamboo leaf green snakes, vipers, rattlesnakes, etc. After biting, local manifestations are caused by continuous bleeding in the wound, blood stasis and tissue necrosis appearing subcutaneously, blood blisters, blisters, severe pain in the wound, toxins spread to the proximal end, and swollen and painful adjacent lymph nodes, which can cause chills and fever, heart rate and arrhythmia, irritability or delirium.

The third type is mixed poison: such as cobras, vipers, etc., which have nerve toxicity and blood circulation, and their effects on nerves and blood circulation are severe. The wounds of poisoned people are swollen and severely painful, which are manifested as muscle weakness in the limbs, muscle pain throughout the body, difficulty breathing, arrhythmia, circulatory failure, renal failure, etc.

After a snake bite, effective first aid measures can delay the spread of venom throughout the body and gain time for post-hospital treatment.

First aid measures include:

Prevent the spread and absorption of venom: Use ropes, handkerchiefs, plant vines, and cloth belts to tie the proximal end of the wound 5 cm to slow down the spread of toxins in the body; during the transportation process, you must 15                                                                                                                                                                                                                               

Quickly remove venom: Repeat the wound with well water, spring water or tap water.

Su Yang immediately gave first aid to the team member.

Wound incision and detoxification are of great therapeutic significance for the treatment of snake bites.

Su Yang first checks whether there are poisonous fangs in the wound. If there are poisonous fangs, they must be pulled out in time.

Then immediately cut the wound with the "cross" incision, reaching the skin, and then squeeze the wound hard to remove the blood. If it is in the hospital, you can use negative pressure to attract and discharge the residual venom, but here is the wild and there is no such condition, so after squeezing for a while, he began to suck out the venom with his mouth and spit it out.

Afterwards, he used 3% hydrogen peroxide solution to rinse the wound, everything was done, and wound bandage it!

Before bandaging, he went around nearby, found some herbs nearby, chewed them with his mouth, covered them on the wound, and then bandaged them.

"Okay, no problem, but you still have to be careful. You are following me behind. If you have any discomfort, tell me immediately!" Su Yang said.

"Thanks!"

Su Yang smiled, raised his hand and patted the other person on the shoulder, without saying anything.
Chapter completed!
