After exploring no active bleeding, Zhou Congwen turned around and stepped down.

Zhang You felt so angry, but there was no good idea. Ichisuke had a job, and after the surgeon stepped down, Ichisuke would lead the next work.

Zhou Congwen tore off the sterile surgical gown and threw it aside, glanced at the orthopedic directors standing next to him.

"Manufacturers only know a little bit of work, which is also the most basic operation." Zhou Congwen said lightly, "You can't rely on them to keep working."

"Shame, look at it." Director Han, as a perfect supporting actor, took the opportunity to add a sentence.

It's indeed embarrassing, but some things cannot be clearly identified, and once they are clearly identified... the ending is difficult to predict.

Zhou Congwen glanced at Director Han and knew that he had a sense of evil fire in his heart today.

It may not be anger, but Zhou Congwen could already hear the sound of sharpening his knife.

Orthopedics, I think that the department does not touch important organs, and there are few emergency departments, and patients have few problems after the operation, so gradually they have become lazy.

"Director Xu, please communicate with the patient's family and solve the problem." Zhou Congwen did not say anything ugly immediately, "Next..."

As he said that, he looked at Director Han.

"Come to the conference room of the medical office and listen to Professor Zhou's lecture." Director Han said with a cold face, and his face changed instantly, with a spring breeze filled with spring breeze. "You have time, Professor Zhou."

"have."

"Okay, Director Xu will give you 30 minutes. Now let's explain to the patient's family first, and then gather in the conference room."

Zhang You closed his chest while sighing silently.

Zhou Congwen and Han Chu didn’t know what they thought. They raised themselves high and fell down gently? They were all public affairs, so why did they offend people so much?

Forget it, it has nothing to do with me.

As he thought about it, Zhang You suddenly felt a sense of emotion.

I will go and listen to it myself, one is to brush my face in front of Zhou Congwen; the other is to watch the excitement, learn and refer to it.

Although it was difficult for Zhang You to solve the problem of having a 9cm toothpick in his heart alone, he was still very skilled in closing his chest. He seized the time to finish the operation, sent the patient to the ICU, changed his clothes and rushed to the conference room of the medical office.

The room was full of people and the air was a little dirty. Zhang You bared his big teeth and greeted Zhou Congwen. Director Han said hello and tiptoed to the innermost.

The orthopedic doctors and professors in the group of professors were all very nervous. Only Zhang You was the most peaceful. He suddenly felt that it would be great if this was the case.

Looking at the people around him with a big teeth bare, Zhang You saw Zhou Congwen and Director Han whispering, talking and laughing, just like an old friend for many years.

Zhou Congwen is really not simple to get along with someone like Director Han. Zhang You seems to have become clearer in his understanding of Zhou Congwen, but after careful observation of Zhou Congwen, he feels that his young face is becoming blurry.

This is something that young people can do? Zhang You don’t think so.

If I switched myself to Zhou Congwen's position, it seemed that I could not communicate with Director Han in such a relaxed tone.

After a while, Director Xu walked in with a look of frustration.

Zhang Youxin feels sad.

If such a big thing happens, no one can be happy. Not to mention being happy, it is considered a big deal to be able to squeeze out a smile with a grin.

And he had to face Han Chu's thunderous anger, and Zhang You even felt more or less sad about the death of a rabbit and the fox.

"Sit down." Zhou Congwen saw Director Xu come in and smiled faintly, "Let's talk about how to avoid such things happening today."

"Professor Zhou, many people have not heard you talk about why it happened, why would you say it again?" Director Han reminded.

Zhou Congwen nodded and repeated what he said on the operating table.

Although there is no physical object and it looks a bit boring, Zhou Congwen's speech is easy to understand, and there are many more descriptions than the few words on the operating table. The doctor below gradually became fascinated by it.

"This is the principle. I have encountered... reading the description in the literature, there are more patients with pulmonary embolism."

"But, there is no need to give up on food because of choking." Zhou Congwen said lightly, "Let me talk about how to avoid similar situations again."

"First, the incidence of cardiac cement embolism after surgery is 3.9%. Excessive number of vertebral shaping at one time is an important risk factor for intracardiac cement embolism."

"I can't chew too much, but I'm right. So when the quantity is not available at the beginning, it's best to control the quantity below two vertebrae. If there are too many, it's easy to get into trouble."

"Second, paravertebral vascular leakage of bone cement may be related to the premature infusion of bone cement, the bone cement has not yet entered the toothpaste period, the injection pressure is too high, the position of the puncture needle, etc., causing the bone cement to flow back to the right heart through the vertebral vein."

"Director Xu, ask you a question - what is the toothpaste period?"

Zhou Congwen suddenly asked a question.

Director Xu was stunned, embarrassed and didn't know how to answer.

Zhou Congwen smiled slightly, "Maybe it is hard to say a simple theory, so give an example."

Director Xu's eyes turned dark. He had only seen the toothpaste period, but Zhou Congwen's understanding of bone cement was obviously much deeper than himself. If he talked about something specious at this time, he would definitely not be able to get away with it.

If he really talks nonsense, Zhou Congwen may not be spoiled and pretend not to hear him.

It was embarrassing and disgraceful, Director Xu's face looked grim and ugly.

"No?"

"Well, I won't raise it." Director Xu said.

Zhou Congwen smiled slightly, but his smile became stronger and stronger, as if he had picked up a joke.

Director Han shook his head, and the doctors below looked confused.

Alas, Zhang You sighed, why is it like a child? Zhou Congwen is really good.

"Then I'll say it. If you don't understand, go back and look for information." Zhou Congwen quickly became serious, "Take an example of today's patients."

"The reason for cement blood vessel leakage is that the pressure in the vertebrae is higher than the venous pressure in the vertebrae and the rupture of the vertebrae venous walls causes bone cement to penetrate into the vertebrae basal veins in the vertebrae.

The leaking cement then enters the lumbar segment vein through the paravertebral vein and eventually enters the inferior vena cava and right atrium, resulting in cardiac perforation and pericardial tamponade.”

"Pre-operative imaging examination evaluates the diseased vertebrae. During operation, the needle tip reaches the front 1/3 of the center of the vertebrae, which can effectively avoid the venous plexus in the vertebrae, and can also make the bone cement diffuse more evenly in the vertebrae, thereby reducing the occurrence of bone cement leakage."

"third……"

"sixth……"

"eighteenth……"

Zhou Congwen broke the PVP surgery and crushed it. Many complications were taken into account. Combined with the surgery, even Zhang You, director of Xiong Ke, could hear clearly.

Even Zhang You had a bold idea - the surgery is so simple that you can do it yourself.

This idea became more and more real, and Zhang You even had a little itchy palm.
