Ask Sword

General Yunhui's mansion is located in Xuanyangfang on the west side of Dongshi. The galloping carriage stopped outside the gate. Li Wei jumped out of the carriage first, followed by Li Ang.

The two hurriedly saw the general's wife covering their faces and weeping, and the pale-faced General Yunhui Chen Changxiao himself, and rushed into the house.

Chen Jiada Lang lay on his back on the bed, his face was like gold paper, breathing hard,

There was a long and narrow sword wound on the outside of his thigh, which was full of blood.

Sitting next to the bed was a middle-aged Nian teacher who was invited temporarily - he was sweating profusely, releasing his Nian power, and forcibly closing the gap on Chen Dalang's legs.

Even so, the blood oozing from the wound still flowed all over the ground.

"A cut artery."

Li Ang took a deep breath after checking the situation. Fortunately, the General's Mansion found Nian Shi to stop the bleeding in time, otherwise the injury would be enough to kill him ten times.

"Doctor, you must save Da Lang, he is still young."

"I try my best."

The patient's family members were completely useless in the room. Li Ang told them to leave the house, took out a tourniquet from the medicine box to stop the bleeding of the injured, and then sterilized his palms and surgical tools.

Then Li Ang opened the cut surface of the wound, found the cut blood vessel, sewed it up with gut that can be absorbed by the human body, and then sewed up the flesh with fine silver thread.

But Chen Dalang's will still unavoidably sank.

Pale and cold skin, tachycardia, weak carotid pulse

Li Wei asked in astonishment: "Why is Risheng Chen Dalang still awake?"

"Blood loss exceeds 30% of the total blood volume, hemorrhagic shock."

Li Ang quickly said: "Now there are only three ways left, one, drink the pulse and come back;

Second, give a large amount of isotonic balanced salt solution;

Three, blood transfusion. "

Before Li Wei could ask what kind of magic medicine Pulse is, Li Ang went outside and found General Yunhui and his wife who were waiting anxiously, "General, Chen Dalang is in critical condition now and needs a blood transfusion to save him from shock."

Chen Changxiao asked in amazement, "Blood transfusion?"

"Transfuse a part of other people's blood into the body of a patient who has lost blood, so as to make the heart, liver, spleen, lung and kidney that are about to fail work again."

Li Ang said quickly: "It's equivalent to refilling the oil lamp with fuel."

"Is it okay to transfuse my blood?"

Chen Changxiao took a breath and said, he had a son in his middle age, and he loved his children very much. This time, he himself asked his eldest son to perform martial arts, and a tragedy happened.

Naturally, at this time, I will not be entangled with the folk concept that "Qi and blood are the foundation of human beings".

Li Ang shook his head and said, "The blood types may be different.

Agglutination may occur depending on the blood type. "

Li Wei's eyelids twitched, and he hurriedly asked, "Is it Risheng's blood type A, B, and C that you talked about today?"

"What blood type?"

Chen Changxiao didn't understand, so Li Ang didn't have time to explain so much, so he turned to Li Wei and said, "It takes time to test the blood type, and Chen Dalang probably won't be able to wait so long."

"Then draw my blood for transfusion."

With a serious expression, Li Wei quickly said: "Risheng, haven't you tested before? I have type C blood, and there is no A and B antigens in the turbid blood.

Therefore, when meeting blood of other blood types, agglutination will not occur. "

Li Ang raised his eyebrows and said, "Are you sure?"

"Um."

Li Wei gritted his teeth, "Da Lang and I are siblings, even death"

"It's just a little blood draw, it's not that serious. At best, it's the level of going to the swamp to get naked and being bitten by a leech."

Li Ang patted Li Wei on the shoulder, took him back to the house, took out a cotton swab from the medicine box, disinfected Li Wei's wrist, and then used a syringe to slowly draw blood and transfuse it.

After everything was dealt with, Li Ang sterilized his palms and surgical instruments, opened the door and walked out of the house, shaking his head at the restless General Yunhui and his wife.

Seeing Li Ang shaking his head, the general and his wife felt dizzy for a while, and subconsciously called out, "Da Lang!"

Li Wei, who was chasing after the cotton swab on his wrist, also asked tremblingly: "Risheng, is blood transfusion still not possible?"

Li Ang said inexplicably: "Okay, I didn't say no."

Li Wei was stunned, "Then why are you shaking your head?"

"Squatting by the bed for too long, my neck is sore."

After all, Li Ang ignored the wonderful expressions on the faces of the generals and his wife and Li Wei, and said, "The hemorrhagic shock has improved, but whether you can live in the future depends on Da Lang's own good luck.

What really kills is wound infection. "

"Infect?"

"It's a malignant sore, festering."

Li Ang briefly explained the doctor's instructions, such as the bandages used to wrap the wound must not be contaminated, alcohol and spicy food are prohibited during the recovery period, and more dates, oranges, milk, lean meat, etc. should be eaten.

The general and his wife sent Li Ang and Li Wei to leave with great gratitude. Before leaving, they wanted to give a gift, but Li Ang refused.

As for the avenue wound, hemostatic suture is just the beginning, and the subsequent prevention of wound infection is the key.

In the absence of anti-inflammatory drugs and antibiotics, wound suppuration is basically equivalent to a death sentence with a reprieve, or even the death penalty.

Sitting in the carriage of the General's Mansion, Li Ang thought about all kinds of information about the wound inflammation, with a serious expression, he murmured: "The Jing monk in the Persian Hu Temple yesterday was indeed half right.

Bloody disaster. "

"Risheng, you've done a good job."

Li Wei was full of blood, and after a tube of blood was taken away, his face was only slightly pale,

Seeing that Li Ang's brows were tightly frowned, he tried to comfort him, "I used to serve as a soldier in a border town, and my swords had no eyes on the battlefield, so I don't know how many enemies and comrades died because of being cut and bleeding.

Blood transfusions are unheard of,

In the case of Chen Dalang, Hua Tuo was already reborn if he could be rescued.

If you can promote it and rescue wounded soldiers extensively, His Majesty will not reward you too much. "

"If he is saved, Hua Tuo will be reborn.

It can't be saved, it's just a quack doctor hurting people. "

Li Ang shook his head and sighed.

According to his plan, the first aid method of blood transfusion should wait until the doctors of Xuegong have done enough relevant experiments before putting it on the table.

Now the eldest son of General Yunhui has become the first subject of blood transfusion first aid. If he dies from subsequent wound infection, blood transfusion first aid may also be a scapegoat.

If you want to eliminate the paranoid concept of blood transfusion among the people, you don't know how much effort it will take.

‘Is it necessary to make anti-inflammatory drugs and antibiotics countless steps in advance?

Under the current conditions, is it really possible?’

Li Ang was deep in thought. Anti-inflammatory drugs are drugs that can inhibit inflammatory reactions, and antibiotics are one of anti-inflammatory drugs, which specifically refer to heterogeneous secondary metabolites produced by microorganisms or higher animals and plants that have anti-pathogen or other activities.

Synthetic and semi-synthetic anti-inflammatory drugs, whether it is paracetamol, ibuprofen, or metronidazole, etc., the synthesis process is too complicated,

I don't know how many times more difficult than making vitamin B12 from pork liver.

And the antibiotics—

Sulfa, chloramphenicol, streptomycin, and, penicillin.
