This doctor has a system

Chapter 497 561. Isn’t this reasonable?
"This patient was diagnosed four years ago and has been taking oral targeted drugs, but the effect has not been good. The current situation is not optimistic."

"She has been waiting for a heart and lung transplant, but there has been no news of a suitable donor."

"However, in the past two years, some experts abroad have used Potts shunt surgery to treat children with pulmonary hypertension, and the results are said to be quite good."

Gao Feng paused for a moment when he said this, and everyone immediately understood his thoughts.

"Director Gao, do you want to perform a Potts shunt on the patient?" asked Director Chai.

"Yes." Gao Feng nodded. "Although Potts shunt is rarely used in the treatment of adult pulmonary hypertension, I carefully read the relevant information after returning home and found that this method is very feasible."

"It's just that the technique needs to be changed."

"Do it with intervention?" Director Chai asked.

"Yes, so I sent the patient directly to our interventional department." Gao Feng nodded and Li Youliang, who was following behind him, hurried up.

"Please go to the demonstration room. Director Gao has made a PPT."

That's right, Gao Feng spent two days to prepare a PPT. Since the Potts shunt technique has not been performed in the Provincial Hospital, you certainly cannot expect the doctors in the interventional department to know much about it.

Everything has to start from scratch.

"As we all know, conventional surgeries are performed with thoracotomy, and there are certain objective reasons for this," Gao Feng said while holding the microphone. "Children's blood vessels are very thin, and they are not naturally friendly to our interventional department. There is nothing we can do about it."

Adults obviously do not have this defect, which is why Gao Feng first thought of interventional surgery.

"Another thing is that if you do it under thoracotomy, you will need extracorporeal circulation support."

“This one could be avoided with intervention.”

As soon as these words were spoken, Director Chai and others immediately opened their eyes wide.

As we all know, many cardiac surgical operations require the support of extracorporeal circulation. Cardioplegic fluid is needed during the operation to stop the heart from beating so that the operation can continue.

From this perspective, extracorporeal circulation is an extremely great invention that makes many impossible operations a reality.

However, extracorporeal circulation is certainly not without disadvantages. For patients with idiopathic pulmonary hypertension, due to the excessively high pressure in the pulmonary artery, the risk of complications after cardiac arrest is much higher than that of ordinary people.

These risks can theoretically be avoided if the operation is performed under intervention and extracorporeal circulation is avoided.

"In a nutshell, it was a transcatheter interventional treatment method, where a covered stent was implanted between her descending aorta and the left pulmonary artery to establish a shunt between the systemic and pulmonary arteries."

So the question is, how to do it specifically? Director Chai and others were confused.

"First we need to complete the puncture from the descending aorta to the pulmonary artery"

"Director Gao, I have a question," Director Shao said, "Do we need to use X-ray-assisted digital subtraction angiography (DSA) to locate the vascular puncture?"

Without waiting for Gao Feng to answer, she continued, "I'm afraid this is too difficult."

They had performed such operations before, and sometimes multiple punctures were needed to succeed, and failure could easily lead to massive bleeding during the operation.

The patient's pulmonary artery pressure is so high that if bleeding occurs, it will be a big problem.

I guess it's impossible to stop the bleeding.

The most likely consequence is a banquet.

Gao Feng had already considered this problem. It would be very tricky for others, but for him, haha, sorry, I can cheat.

However, he was not going to solve the problem this way this time. Not only did he not want to waste his hard-earned skill points, but he also had a better way.

"Director Shao, don't be impatient." Gao Feng said with a smile, "I'm going to talk about this next."

"Image fusion technology including CT can be used to provide clearer and more accurate positioning for vascular puncture."

"Please watch the VCR!"

"This is the image that I created yesterday with Director Li Xianmin from the Department of Imaging. Let's take a look."

"If it is assisted by real-time imaging like this, do you still think there is a problem?"

Looking at the clear dynamic images, everyone in the audience had joy in their eyes. It was so awesome.

Director Chai clenched his fists excitedly. His eyes were already looking further. This technology would be of great help to the interventional department.

With this combined image fusion technology covering CT, some diseases that could only be treated with surgery in the past are no longer off-limits for them.

"In this way, the risk of bleeding during puncture of the atrial septum can be greatly reduced." Director Shao said with a smile.

"No, I don't plan to use the atrial septal puncture needle." Gao Feng said.

After these words were spoken, Director Shao and others were collectively stunned for a moment. You know, using a septal puncture needle for puncture is the most classic operation method, and everyone is using it.

"Then what are you going to use?" asked Director Chai.

"Is it radio frequency drilling?" a director in the audience asked, "I saw the doctors there using it when I visited and studied at the Mayo Clinic last year."

Compared with thicker atrial septal puncture needles, radiofrequency perforation has obvious advantages.

However, this technology has not yet been developed in the Provincial Hospital, and it seems a bit like a good cook cannot cook without rice to talk about it now.

"No, I plan to use laser drilling." Gao Feng said with a smile, "This way it will be less traumatic."

"This..." Director Chai didn't know what to say, "Does our hospital have this technology?"

Of course not. Not to mention the Provincial Hospital, even in Xhe Hospital, there is no technology for laser drilling.

"It doesn't matter. The principle is very simple. We can assemble one ourselves." Gao Feng said confidently, "I have already given the instructions. We can use it for experimentation in two weeks at most."

Everyone looked at each other in bewilderment. They could accept the improved surgical procedure, but they had never seen an instrument specially made for a single operation.

Director Chai finally realized that this operation was not as simple as he thought.

This is a high-end game!

But it’s too advanced, and my brothers can’t keep up.

Director Chai looked worried, "Director Gao, we don't understand these."

He was very worried that not only would he be unable to help, but he might also hinder Gao Feng.

"Director Chai, the application of Potts shunt in the treatment of adult pulmonary hypertension is still in the experimental stage. There is no clear statement at home and abroad at present." Gao Feng said, "We are also actively trying. Don't put too much pressure on yourself."

"Okay, I'll follow your instructions." Director Chai breathed a sigh of relief. He had made up his mind and decided to just stop using his brain. He would just be a good assistant and do whatever Gao Feng asked him to do.

If Gao Feng knew what he was thinking, he would definitely be very satisfied.

He already had a clear idea of ​​the next operation in his mind. The most important thing now was to perfect some details. He did not need anyone to give him advice. What he lacked were some highly skilled executors who obeyed his orders.

Director Chai is obviously such a person. Gao Feng continued to talk, and this time no one interrupted him. The reason was simple: most directors felt that their brains were not enough.

"Director Shao, do you understand?" a director at the side asked in a low voice, "I have never done the operation that Professor Gao talked about."

"He..." Director Shao frowned, she didn't know what to say, "Just listen first, and ask again after it's over."

"Your words and deeds have greatly inspired Chai Dehui. You have gained 2 skill points." The system prompts.

Gao Feng was stunned for a moment. There were more than 10 people sitting below, so how come only Director Chai was inspired?
Is there something wrong with other people's brains?

Or, I'm not targeting anyone, everyone here is garbage?
"Director Gao, I don't quite understand." A piece of trash, no, Director Shao stood up, "Generally speaking, when we insert a covered stent, shouldn't we..."

She asked the question that most people ask: What you said is not quite the same as what is in the book!

Is what the book says necessarily correct?

Of course not, especially in medicine.

For some diseases, the treatments written in medical student books are at least 5-10 years behind the latest guidelines.

even longer.

The reason is very simple. The scholars who wrote the textbooks do not know which treatment method will achieve a breakthrough. The book has already been printed. It is impossible to change it, which is not realistic.

Anyway, medical students will receive updated knowledge after entering the hospital.

Besides, do you really treat patients according to what is written in the textbooks?

"Director Shao, this is a very good question," Gao Feng said. "It was true in the past, but now we have a better method. When inserting the stent, we can..."

"This can greatly improve the success rate and reduce the damage to blood vessels."

"I'm sorry, Professor Gao, I've never heard of this." A director stood up and asked, "Is this the latest guideline?"

"The guidelines haven't changed yet," Gao Feng replied, "but there's an article in Nature describing this surgical method, so it should be added to the guidelines later."

"Which issue?" Director Chai asked, "I'll take a look later."

"It should be the next issue or the one after that."

"What?!" Director Chai was stunned. "Professor Gao, I don't quite understand you."

"I submitted the article, and the editor told me it was accepted," Gao Feng explained, "but he didn't tell me which issue it would be published in."

According to past experience, it will be either the next issue or the next one.

"Doesn't this make perfect sense? What is it that you don't understand?"

The scene suddenly became very quiet. Li Youliang, who was playing with his phone, couldn't help but raise his head. What was going on? Wasn't the discussion just now quite heated?
Why are you suddenly silent?
"Director Gao, you are really..." Director Chai held it in for a long time, and finally said four words: different from ordinary people.

After another 20 minutes, seeing that no one raised any more questions, Gao Feng waved his hand to adjourn the meeting.

"Director Chai, what do you think?" Director Shao came over as soon as he returned to the office.

"How can I watch? I'll just sit and watch." Director Chai drank a cup of chrysanthemum tea. He had just said too much and his mouth was dry.

"I don't think it's very reliable." Director Shao whispered, "It seems that this operation is completely imaginary by him."

"All geniuses are like this." Director Chai said as a matter of course.

"You seem to trust Professor Gao Feng very much."

"You're talking nonsense." Director Chai thought her words were incomprehensible. "Look at all the things he did before. Which one did he fail to accomplish?"

He succeeded in everything he did, including copying drugs, developing testing equipment, developing reagents and consumables, and researching orphan drugs. He won national awards, became a disciple of an academician, and won the Lasker Award for Medical Science.

None of these things can be done by ordinary people.

"Anyone who can accomplish one of these things will be a remarkable person." Director Chai's eyes were full of longing when he said this, "They have accomplished all of them!"

"So, now I believe whatever he says he can do, and I am willing to cheer for him."

"Besides, I have no choice but to believe it." Director Chai whispered to Director Shao, "Do you know what Director Guo told me?"

Dean Guo called him directly to his office and told him directly that he must cooperate fully.

His mind suddenly tensed up and he asked to what extent he would be required to cooperate.

"Do whatever he tells you to do, and make sure he's satisfied." Dean Guo said bluntly, "Do it to the letter, without any bottom line!"

Director Chai was stunned. "I'm going to kill people and set fires, too?"

"Gao Feng is such a kind-hearted person, would he let you do such a thing?" Dean Guo said dissatisfiedly, "If he said that, it means there is something wrong with you!"

"So let's cooperate with him fully." Director Chai said, "And I think Director Gao Feng is now confident. After listening to his lecture just now, I seem to have a better understanding of this technique."

He planned to learn more about it after returning and have a good discussion with the directors in the department.

"Hearing what you said, I feel relieved." Director Shao said. She also knew that Gao Feng was very capable, but after all, they were not colleagues who she worked with day and night, so there was always a sense of unreality.

But Director Chai is different. She has worked with the other party for so many years, and the foundation of trust between them is very solid.

She believed in the other party's judgment and began to look forward to the operation led by Gao Feng.

Fengxin Technology Laboratory

Yue Penghui is communicating with engineers from several laser equipment manufacturers.

“Brother, can you get it done this week?”

"This week?!" one person asked in surprise, "How can it be so fast?"

"It's impossible unless we stay up all night and work all night long!" others echoed.

Yue Penghui was immediately delighted, "Can we stay up all night?"

As soon as these words were spoken, the scene suddenly became quiet.

"Young man, what do you mean by this?" asked a middle-aged man in his 40s, who was the leader of the group of engineers.

"Brother, we are in a hurry." Yue Penghui said, "Thank you for your hard work."

"No matter how anxious you are, you can't destroy us like this!" The middle-aged man said dissatisfiedly, "I'm 45 years old this year. Isn't it going to cost me my life to work all night long?"

"Yes, we are here to do business, not to risk our lives." Several people echoed.

"That's right! One week is not enough. No, even two weeks is not enough." The middle-aged man said, "The fastest it will take is three weeks, and even then we still have to work overtime!"
