"It's definitely not true, it's just that if you are a five-step snake, the toxin will spread quickly. The ancients summed up their experience and found that after being bitten by a venomous snake, the activity would accelerate the spread of the toxin, so there was a saying that death in five steps. ”

"Then Master Fan, I saw you tying just now, is there anything special about this, aren't you afraid of infection?"

"As long as there is no direct contact with the wound, tie the path of toxin transmission, which is blocking the speed of blood flow.

Because snake venom is a neurotoxin, it spreads rapidly through the bloodstream.

The material of the lashing is selected, and the upper part of the bite is 5~10cm with a strip of cloth, gauze, bandage or rope to do a circular ligation, the sooner the better.

However, at the same time, it must be noted that the ligature is too thin or the ligation is too tight, especially if the finger (toe) end is ligated, which is prone to necrosis and leads to amputation of the finger (toe).

So, don't use a cable tie that's too thin like mine, a wide and flat strip of cloth is fine, and it's not deep and very tight.

After all, its role is also limited, and it only restricts superficial venous and lymphatic return for a short time.

Finally, as long as the wound has been treated, the ligature can be removed after antivenom treatment. ”

After speaking, Chen Fan ripped off the strip of cloth that tied Liu Ming's legs.

At this time, he saw some questions about snake venom and wound treatment again, so he explained:

"Generally, for venomous snake bites, especially if the time delay is not long, then the best way is to open the wound for debridement and detoxification, so that the lymphatic fluid containing snake venom can be discharged as soon as possible, the limbs will be swollen quickly, and the symptoms will be relieved quickly.

After strict disinfection, make a "+" shaped incision with the poisonous snake's tooth marks as the center, go deep into the subcutaneous tissue, and thoroughly rinse and debride with 3% hydrogen peroxide and normal saline, so that within three minutes of being bitten, about eighty percent of the snake venom can be removed.

However, I didn't have such good conditions before, and there may be a little risk of infection in the wound, but fortunately, I boiled salt brine, I want to have snake venom, plus a little salt to clean the window, and it will heal in two days at most.

However, when cutting the wound, it should not be too deep, today I am a little deep, and my hand is slippery, which is considered a slippery hand. ”

Chen Fan smiled at Liu Ming.

However, there is no way, Chen Fan is his savior, not to mention that people are still doing business and doing live broadcasts!

Forgive him yourself!

Therefore, it is necessary to pay attention to fluid expansion, acid correction, anti-infection, prevention and treatment of bleeding, diuretics and high-dose vitamin C, timely correction of water and electrolyte disorders, and give comprehensive treatment measures such as nutritional support therapy to protect and maintain the function of important organs.

Later, bother your girlfriend to pick more mangoes for you to make mango juice, you need to drink more of it. ”

"In terms of the application of anti-pit viper venom, if conditions permit, after diagnosis, the first application of refined anti-pit viper venom 0u intravenous infusion can neutralize the toxins that have not yet bound into the human body, block the damage of snake venom to the function of multi-system organs of the body, and is the key to the treatment of snakebites.

Generally, the dosage is decided according to the severity of the condition, 1 vial (6000u) for mild symptoms, 2 vials for severe patients for the first time, and 1~2 vials can be used as appropriate within 24 hours.

Be alert to allergic reactions, use anti-allergic drugs and corticosteroids at the same time, and closely observe the whole body.

Also, pay attention to allergies, a small number of people will be allergic to dexamethasone injection. ”

After answering the question, Redmi's mobile phone was full of barrage, and at the same time, the other people present were also dumbfounded.

Especially Liu Yan and Zhang Xuejuan, women! I especially appreciate talented and handsome people.

Not only that, but this guy has a very strong practical ability when he says this.

Especially Liu Yan, when she saw Chen Fan's mouth flying up and down, she was really excited.

"Well, all right, why are you all looking at me!

Chen Fan stopped, saw the adoring eyes of several people, and forked.

"Master Fan, how did you grow your brain, you know so much, were you born to study medicine?"

Liu Yan said.

"That is, the head of the talk is the Tao, what dexamethasone, what is the cross knife, depending on the technique you just had, this is still the ability of many years of clinical doctors. ”

"Okay, okay, don't put a high hat on me, my family knows my own affairs. I'm a miscellaneous, basic and basic, just barely eating.

I'm a computer student, not a doctor. ”

"Uh, the computer, that'...... Then Fan Ye, can you share your hot spots?"

Now relieved, Liu Yan finally remembered that the phone was fully charged.

There is no electricity and no network, this is not good, doesn't Fan Ye have high traffic?

"That'...... Can I try?"

To be honest, Chen Fan has not tried signal sharing on the second mobile phone.

So, his mind activated, calling the system: ァ新ヤ~(8)~1~Chinese 網ωωω.. còм

"System system, can I share this signal as a hot spot?"

"Ding, hello host, it's okay!, but every time you start, you need to consume 500 points. ”

"Okay, open it for me, isn't it just five hundred points?"

Speaking of points, Chen Fan remembered the serum he bought in the system mall with points before.

10,000 system points, although this time he survived on the desert island, his system points have accumulated to more than 100,000, but it is still far from enough for him to upgrade the storage space and upgrade other functions!

"By the way, this time the money spent on that guy is 10,000 system points, and I will definitely find him to compensate for it when I go back. ”

Chen Fan exchanged a hot spot to share at this time, and looked at Liu Mingdao with some resentment.

"Okay, that's it, you can just connect directly. ”

"Well, I found it, it's the man at the top of the food chain, right?"

"Wow, I can't imagine that you are so narcissistic. ”

"Master Fan, you are so sassy!"

The three of them complained one after another, and Chen Fan didn't bother to explain more to them.

"Let's play, let's play, anyway, it's just a power bank, and when the phone is out of power, there is only a queue to charge." ”

Chen Fan himself now, the mobile phone is more of an ornament for him.

So, he didn't care much about these things.

"Damn, I almost forgot, my salt hasn't been boiled yet! Don't move here yet, I'll go down and look at my salt, and I'll come up when it's ready."

Don't wander around!"

After Chen Fan finished speaking, he ran down the mountain.

And the three of them finally shared the hot spot, and they were worried that Chen Fan would run away.

"You're gone, what should we do if we don't have a hotspot on our phone?"

As a last resort, Chen Fan pretended to throw the Redmi phone in place and let them go as a hot spot. The fastest mobile phone terminal for network update::/m.. com/

Of course, he is the one who locks the screen, and these three people, that is, temporary friends, still understand the truth of making simple words.
