Da Song a knife

Chapter 461

Regarding Zhang Sijiu's question, Gu Qingzhou looked up at the sky, feeling helpless: "It's only about seven or eight or ninety years. After all, I'm so old—who can tell when it will be?"

The blue veins on Zhang Sijiu's forehead twitched: "So what disease do you have?"

Gu Qingzhou coughed and looked left and right, but he didn't dare to look at Zhang Sijiu: "Old illness. When people are old, they are old illnesses!"

Zhang Sijiu turned his head and left: This old man!
However, although Gu Qingzhou was a little unreliable, he really gave Zhang Sijiu his best.Basically, even the daily focus is on Professor Zhang Sijiu.

After a period of time, he expressed disapproval of Zhang Sijiu's previous behavior of learning everything: "Human energy has always been limited. Only by specializing in one thing can one achieve something. Grasp everywhere, and finally I'm not proficient in everything, I just take a erudition."

Zhang Sijiu was taken aback, and asked Gu Qingzhou: "But if you don't know how to prescribe medicine and feel the pulse, how can you heal people?"

Gu Qingzhou sighed: "The Yellow Emperor's Internal Classics say that the superior one cures minor illnesses, the middle one treats minor illnesses, and the lower one treats serious illnesses. In fact, it is not always the case. If you can regulate your body from the beginning so that it does not get sick, it is naturally the best. But most people in the world don’t know how to prevent and treat diseases, even minor diseases. When they need a doctor, they often become serious diseases.”

"What you and I want to take care of is this kind of serious illness and disease. You can't live without getting rid of the lesion, and you can't live without using a weapon! Since we are in charge of this kind of disease, what do we learn from those? As long as we can see where it is As long as you know how to cut it, how to sew it up, and what medicine to take afterwards to save your life! As for the body conditioning—that’s another doctor’s business.”

Gu Qingzhou looked at Zhang Sijiu burningly: "Do you know why I am the only one who has learned this subject of mine? You masters, but you all learn other common medical skills?"

Zhang Sijiu subconsciously asked: "Why?"

Gu Qingzhou raised his hand: "Because of these hands, not everyone can learn this craft. It seems that the knife is light, but only the person who really holds it can understand, how the knife is How heavy is it? How much does each knife weigh?"

As a surgeon, Zhang Sijiu understood the meaning of these words better than anyone else.

The scalpel tests one's heart, one's physical fitness, and... one's talent.

If a person's psychological quality is not strong enough, it is difficult to do well in fine surgery.

The more major the operation, the more challenging these are.

If the mentality is not stable enough, during the operation, as long as the hand shakes, it is likely to injure the nerves and break the blood vessels-these are the scariest things in the operation.

Moreover, not everyone can gradually adapt after seeing too many bloody scenes.

More people will become more and more resistant, and the psychological pressure will also increase sharply, and such a state will not make it to the operating table.

Zhang Sijiu looked down at his hands, then at Gu Qingzhou, and finally nodded: "I listen to Master."

After this conversation, Gu Qingzhou completely changed the teaching routine.

At the same time, Gu Qingzhou was also quickly accepting Zhang Sijiu's tricks - such as washing with salt water, such as disinfecting with alcohol, such as fumigation and drying gauze.

Zhang Sijiu was also opened the door to a new world by Gu Qingzhou: the dirt that cannot be cleaned well by salt water washing can be washed with slightly thickened wort as the washing material - the intestinal anastomosis operation back then , to wash the inner wall of the abdominal cavity is to use the boiled barley soup.

At the same time, Gu Qingzhou also smeared the suture with fresh chicken blood to achieve a sealing effect.

The reason why this effect can be achieved is actually very simple: the blood coagulates very quickly. After the chicken blood smeared on the suture clots coagulates, it can block the small gaps in the sutures, preventing bleeding from leaking into the abdominal cavity, and at the same time letting the intestines The stuff can't seep out and contaminate the abdominal cavity!

You know, once the peritoneum is infected, it will cause acute abdomen, and it will also cause death.

As for the suture thread, the wisdom of the ancients was also exceptionally powerful.

Animal protein threads can easily cause allergies and rejection reactions.Especially the rough fish gut that Zhang Sijiu is using now.

Therefore, the ancients used threads made of mulberry bark.

When it is dry, it is very light and easy to store. When it is used, it only needs to be boiled with water for a while, and the mulberry thread will be soft, and it is also very flexible, and it can be absorbed even in the later stage——

Gu Qingzhou took Zhang Sijiu to make a mulberry thread. The process was really cumbersome, from taking the skin, beating the skin, soaking in water, drawing the thread, and processing...

It took a whole month to make just a few finished sutures.

But after trying the effect on animals, Zhang Sijiu was surprised to find that it was indeed very effective——

At this moment, Zhang Sijiu's only feeling was: what a pity.What a pity.Why is such a good thing not passed on?
Seeing Zhang Sijiu's bumpkin look, Gu Qingzhou finally felt complacent: "Look, I am your master for nothing, right? Little girl, learn carefully. Your master and I still have a lot of skills!"

Zhang Sijiu was convinced: "The things left by the ancestors are really amazing, and they should be passed on."

Time flies by in studying medicine and research and development.

During the autumn harvest, before he had time to verify the efficiency of the improved harvester, Yang Yuanding came to say goodbye to Zhang Sijiu.

Yang Yuanding sighed: "My grandfather's health is not very good, we have to rush back. This time, I don't think he will come again. Even my father will take Ding You three years."

The news came so suddenly that Zhang Sijiu was a little taken aback: "Your family is going to leave Mianzhu County?"

Although both Zhang Sijiu and Yang Yuanding were mentally prepared for the separation, when this moment came, everyone felt that it was too sudden and too fast.

They still have a lot to do.

Penicillin has not been produced until now, but the oil factory has been opened, but the oil production rate has not been increased, and the raw materials are too few——

Yang Yuanding nodded with a bitter face: "After I leave, I guess I will still be pressured to study. At that time, I will definitely not be as comfortable as I am now. Besides, I don't know if I will reveal my secrets——"

Zhang Sijiu is not so worried about this matter: "Don't be afraid, be smarter when the time comes, and pretend to be sick when you see something wrong. Just pretend you don't remember. Anyway, you almost died when you fell into the water. If you got water in your brain, don't you?" Aura is also a reasonable thing."

When Yang Yuanding heard this, he immediately laughed angrily: "What do you mean your brain has flooded?"

However, he also knew that Zhang Sijiu was teasing himself, and he wasn't really angry. He just looked at Zhang Sijiu with a sad face: "I'm afraid that something will happen to you. Your family is like this. I'm leaving, and no one will protect you." , you must stop being so arrogant."

　I will stop updating tomorrow... I have influenza A, and my fever has reached 39.5...
