Chapter 426 Lu Cheng is going to start causing trouble!

"Huh!" Lu Cheng exhaled after transferring the liquid in the wound into the culture tube, and then carefully looked at the situation inside the wound.

In the end, he decided to turn his head and said to Xuan Xuan, who was about to send the culture tube down: "Teacher Xuan Xian, please open a sharp blade as a backup."

I had never been to the operating room of Jingwei Building during my tour, so I was a little puzzled: "Didn't I open a slice? I just saw the one you were holding in your hand? Did you drop it?"

While asking, he walked towards the spare instrument table in the operating room.

"Open one as a backup." Lu Cheng replied without looking back.

The circulating nurse felt depressed after hearing this and turned on the backup. What the hell was the reason? Of course, now that Lu Cheng was the chief surgeon, she couldn't say much.

Qu Hongsheng has never had an operation with Lu Cheng, so he doesn't know the usefulness of Lu Cheng asking the traveling nurse to prepare an extra sharp blade. However, sharp blades are not expensive and are not included in the regular surgical consumables.

He didn't ask any more questions.

But the next moment, Qu Hongsheng understood.

When Lu Cheng called the roving nurse to prepare a sharp blade, Fang Nixin knew what Lu Cheng was going to do. Even Xie Jian knew that he was standing by and used a thyroid retractor to pull the opening that Lu Cheng had just exposed.

A little more open.

Lu Cheng held tweezers in his left hand and a sharp knife in his right hand like a pen. Starting from the incision in the skin, he slowly began to debridement.

But Qu Hongsheng captured Lu Cheng's movements very keenly. Although Lu Cheng's sharp knife and tweezers did not cut off much necrotic skin, Lu Cheng's right hand was moving slightly and quickly.

His movements looked like those of an intern doing surgery for the first time, with his hands shaking nervously, but...

Qu Hongsheng had known about Lu Cheng for a long time, and he estimated that he had performed at least one or two hundred surgeries on his patients, so such a situation would definitely not happen.

Then when you look more carefully, you can find that while Lu Cheng's right hand is shaking slightly, his thumb, index finger and middle finger are constantly changing the angle, controlling the tip and shoulder of the sharp blade, quickly moving on the skin.

And scratch inside the subcutaneous space!

The principle of operation is somewhat similar to the curettage of benign bone tumors in the Department of Osteopathic Medicine. However, bone tumors are generally inside the bone or on the periphery of the bone. They are relatively hard materials. During the scraping process with a curette, there will be tactile feedback.

Where did it get scratched?

The area Lu Cheng is operating now is only soft tissue. It is not easy to complete the scraping action in this area.

If the force is not enough, it will cause no pain. If the force is too strong, the skin will be completely dried out with one knife.

A sharp knife or a round knife can perform amputation, and soft tissue cannot be cut anywhere. This is no joke.

"Xiao Lu, what are you doing?" Qu Hongsheng asked immediately.

From the time Qu Hongsheng got to know Lu Cheng, he slowly and in-depth conducted a small investigation on Lu Cheng. It was not a behind-the-scenes investigation, it was just asking some old acquaintances in various departments. He found that almost everyone in the department was close to Lu Cheng.

People who knew him, whether they were subordinates or professors, all praised Lu Cheng endlessly.

Moreover, Qu Hongsheng does not feel that he surpasses Lu Cheng in terms of knowledge of orthopedics, but that he is much deeper than Lu Cheng in terms of depth in a single subject.

If you don’t understand, you must ask.

Of course, I am also afraid that Lu Cheng will do something wrong, although the chance of doing something wrong is very small.

"Teacher Qu, I am doing debridement. This is a concept that I discussed with some of my fellow interns some time ago. It is a supplement to debridement."

Lu Cheng continued to explain while continuing the operation in his hand: "It can be roughly divided into two parts. The first part is similar to the application of osteopathic curettage techniques in debridement, using micro-operation to avoid damaging normal muscle tissue.

, and can quickly and cleanly scrape away necrotic tissue.”

"The second part is the lacunar theory. Our conventional debridement mainly focuses on removing necrotic tissue and not retaining tissue that cannot be determined to be infected."

"But we feel that the bacteria that infect patients' wounds generally lurk in various cavities. If these cavities can be removed in a limited manner using micro-manipulation, we can ensure that the normal tissue remains to a greater extent."

"And it can clean up infected tissue to a greater extent and reduce the chance of infection recurrence."

"Because according to the principles of normal debridement, the lacunae that can be left open should be kept as low as possible. However, we found by searching the literature that many experts at home and abroad have actually achieved complete debridement during debridement.

The effect is effective, but there is still a recurrence rate between 27% and 43%.”

"so……"

Lu Chengxin picked it up and spoke skillfully, without stopping the movements of his hands.

Although these things were not proposed by Lu Cheng at the beginning, Lu Cheng was involved in the whole process and has been refined. Therefore, Lu Cheng now has a very professional grasp of the relevant data.

After hearing Lu Cheng's words, many people in the operating room were stunned.

The hand-washing nurse looked at Lu Cheng blankly for several times, first looking at the literature, and then looking at some operations performed by domestic and foreign experts, which seemed to sound quite similar.

It doesn't matter if you are at the level of Professor Min Hong or Professor Huang before. Are you so young?

Are you boasting about such a big mouth all at once?

The anesthesiologist didn't think much about it. In fact, when he saw Lu Cheng in the surgical team, he thought of the recent introduction of a very good young doctor to the hospital. The vascular surgery department, burn department and orthopedics department were all competing for him.

Had a fight.

It goes without saying that Lu Cheng is very powerful. Professor Zhang Yuewei of the Department of Vascular Surgery, who is known as the international leader, has all tried to rob Lu Cheng. If he had no skills, he would be Zhang Yuewei's illegitimate son.

But the age doesn’t match up either.

He was not surprised that Lu Cheng would make some big moves after entering the hospital.

After all, a young man like Lu Cheng is talented, capable, and now has a platform and autonomy. If he doesn't create something, he would be sorry for himself.

However, the anesthesiologist never thought that Lu Cheng would choose debridement.

What is the basis of surgery? Every medical student will tell you: debridement, debridement, debridement.

The first step in the development of surgery is debridement. The development of all current surgical techniques cannot be separated from debridement.

Debridement teaches surgeons how to distinguish between necrotic tissue and healthy tissue. The essence of more than 95% of surgical operations is to remove necrotic tissue and then preserve the patient's functions.

However, basically all techniques are derived from debridement, so this aspect has been basically poorly studied in the more than 100 years of surgical development.

Can you still play tricks?

Of course, if they can really pull off the trick, then the Second Xiangya Hospital will really find a treasure this time.

The foundation, what is the foundation, is the cornerstone of everything.

Each discipline has two major experimental directions, one is called clinical experiment and the other is basic experiment.

In clinical experiments, many conclusions or conjectures made are not as influential as the results of basic experiments. Basic experiments are usually done in the laboratory, and once they are done, high-scoring articles can be published.

Why can we publish high-scoring articles? Naturally, the impact is greater than clinical trials.

Some basic clinical skills, such as debridement and suturing, have basically become commonplace operations. After graduating from junior college, students can also know how to suture and some basic concepts of debridement.

Currently, the basic operation being studied internationally is actually various fancy sutures.

No one has ever thought about debridement. It’s not that they don’t want to, but it’s just too difficult.

Therefore, if we can really add something to the outdated basic theory of debridement, then I'm sorry, brother, you don't even want to be famous.

You are all rushing to write about conceptual things in textbooks.

After Qu Hongsheng finished listening, he was stunned for about ten seconds. Lu Cheng thought that Qu Hongsheng didn't want to ask further questions, so he continued his operation, becoming more and more silky and smooth.

It went smoothly, from the skin to the subcutaneous fat layer.

When operating on the fat layer, Lu Cheng has changed another operating mode.

Qu Hongsheng coughed twice, and then asked in confusion: "Lu Cheng, what did you just say?"

Qu Hongsheng is a professor in the Department of Orthopedics and Orthopedic Oncology. He is currently the acting director of the Department of Orthopedics. He was previously a management member of the Basic Medical College. Although he takes an administrative route, it does not mean that he is not sensitive to the development of the discipline.

It's not that Qu Hongsheng didn't understand, but he hoped that Lu Cheng could confirm some of the things he was doing...

Lu Cheng frowned, and Fang Nixin took the initiative to say: "Teacher Qu, Xiao Lu said that he has certain ideas about debridement. However, it is only in the theoretical stage now, and he has not even prepared the preliminary research work on the topic, so he still has

The project cannot be approved for the time being!”

Qu Hongsheng understood it clearly.

It turns out that debridement can still be done this way?

It turns out that debridement can be reinterpreted.

Debridement, and a new understanding!

To re-understand and reinterpret debridement, what is the concept in surgery? It is to redefine initial consonants, finals and part of the tones in Chinese characters. If it can be done, then all concepts,

Maybe everything will change because of this!

The foundation, although simple, is the cornerstone!

Immediately, Qu Hongsheng began to become heated and excited, and asked in a loud voice: "Xiao Lu, how much information have you collected now? What is the result?"

"Have you ever told Li Dongshan about this?"

"he?"

"Didn't he support you?"

"Then you shouldn't come to the Fifth Bone Department." Qu Hongsheng's tone became a little messy, and he was also angry.

It can be said that compared with paving the way for Lu Cheng to advance to a professional title as soon as possible, or to enable his students to gain a foothold in the fifth department of bone science, all of this is compared with what Lu Cheng plans to do.

Get up, this is bullshit!
