With the vascular anastomosis magnetic ring, Zheng Ren quickly shortened the time of the liver-free period to an incredible level after adapting.

The former "world record" was like a piece of paper, broken with one stab. The experimental subject's cardiac arrest, and the seemingly insurmountable obstacle was also successfully crossed by Zheng Ren.

Dozens of surgical training, the shortest time for surgery without liver surgery is 8 minutes and 12 seconds.

This is undoubtedly a huge breakthrough, but it is just the beginning.

Zheng Ren's mental calcification surgery, installing a vascular anastomosis magnetic ring, and opening the portal blood flow during the period. This is the most difficult step that Zheng Ren imagines.

The sudden recovery of heart blood supply, and whether the patient's heart, which has already suffered from heart failure, can hold on to it? This is a question.

Sure enough, within 3 seconds of restoring the blood supply of the portal vein, the experimental subject's cardiac arrest stopped.

After nearly 30 hours of surgical training, Zheng Ren came to a conclusion that the operation must be completed as soon as possible under heart compression.

However, heart compression and violent tremors affect the operation. The heart compression under chest opening and direct vision was too trauma. Even if Zheng Ren barely completed the operation, the completion of the operation was not high.

This means that it is difficult for patients to survive the perioperative period after surgery.

Zheng Ren didn't even dare to go out of the system operating room, and that guy Su Yun was staring at him outside.

Opening the blood flow of the door vein will indeed cause a sudden change in blood pressure, which Zheng Ren cannot solve.

You can't just use a "replacement" skill like a magician, and the liver will change its position.

The vascular anastomosis magnetic ring can solve the problem of long-term liver-free period and is also of some help to the patients in front of you, but it cannot solve all the problems.

Zheng Ren tried ten surgeries, and finally ended his efforts and left the system operating room in desperation.

It seems that there were still several krypton gold treasure chests that were not opened before.

Zheng Ren, who has always had no love for things that are lucky, just kept it aside when he got the box.

In fact, most of these boxes are also experienced.

He glanced at the skill tree of general surgery, which was still one part of the peak, a long time.

Even if several boxes have a huge amount of experience value, it will not allow my general foreign technology to reach the peak level and have qualitative changes.

Zheng Ren came out of the system space.

This time, it was a very troublesome operation. After repeated struggles, Zheng Ren did not get a satisfactory solution.

"Boss, do you think it's not possible for 15 minutes of liver-free period? Want to go to heaven?" Su Yun said contemptuously: "A surgery has a standard time of 3-4 hours. I believe you can complete it within 2 hours. But the liver-free period is at least 30 minutes before, are you really going to shorten it to within 10 minutes?"

"The key is not here." Zheng Ren's voice was a little hoarse, and he said with a voice: "Have you seen the patient's recent echocardiac arousal?"

"Look, I'm in a bad state."

"Well, I'm considering that after opening the blood flow of the portal vein, the pressure changes will lead to cardiac arrest." Zheng Ren entered a state of emergency, without thinking about any flaws or loopholes, and all his attention was spent on how to make the patient end the operation safely.

"Stop jumping... Do you want to open your chest?" Su Yun asked after thinking for a few seconds.

"Cytopulmonary resuscitation is the last step. Liver transplantation has many problems after surgery. It is best to not open the chest and cause greater trauma." Zheng Ren said firmly, "Is there a hospital for vascular anastomosis magnetic ring?"

"I'll contact you." Su Yun said, "Cardous arrest...outside the chest...is not right, we're opening our abdominal cavity."

Zheng Ren was stunned for a moment and immediately said, "Due to the silence!"

The cardioresuscitation method of squeezing the diaphragm is rare in clinical practice and is an unconventional operation method in special circumstances.

After all, there is not enough experience. Zheng Ren, under Su Yun's reminder, worked hard to piece together the possibility of success.

Dry!

This time, Zheng Ren finally found a complete path, and the rest was practice.

He immediately came to the system space, purchased the system operation time, and entered the operating room.

This time, he practiced cardioresuscitation surgery for diaphragm under the diaphragm. It was very difficult, especially without affecting the operation. However, Zheng Ren still did it, and the final successful method of pressing was learned from Fan Tianshui.

When I went out for a meal and encountered a spontaneous pneumothorax patient, Fan Tianshui poked the waiter's chest with a straw. The way of using force was to gather the strength at a point and then burst out.

Zheng Ren remembered that Su Yun had asked Fan Tianshui for advice after that, and he also tried to do it a few times, and it looked decent.

If that guy really takes a look, it should be fine. Zheng Ren can only place his hope on Su Yun. If it really doesn't work, then he can only have Gad Woods' surgery and do a heart compression himself.

Lin Yuan was stunned when he heard this. What's going on?

I had a liver transplant at Harvard, and the procedure took about 3 hours and was at the advanced level of the world's surgical community.

The liver-free period varies depending on the level of the surgeon, and it takes 30-40 minutes.

Su Yun shortened the liver-free period to 15 minutes in just one sentence.

This is not the most critical thing. Boss Zheng seems to be not satisfied with this time!

It is also expected that cardiac arrest will occur when blood flows open to the portal vein...

Liver transplantation, cardiac arrest in open portal blood flow, is not a rare complication. Although Lin Yuan has never seen it with his own eyes, it always exists.

Boss Zheng is a prophet or his level is high to a certain level, and he directly killed himself... He is not a big deal, he directly killed a number of tutors and professors at Harvard Medical School.

The next step is to find a dummy and try the trick? Lin Yuan was a little confused. He could only say a few words at the beginning, but now her thinking can no longer keep up.

"The patient's condition must be at least 100-120 times per minute." Su Yun said, "The key is when will it be."

Zheng Ren said, "After the arteries and blood vessels begin to anastomose, the patient's condition should be relieved."

"It will take another 1-2 minutes to restore normal physiological and anatomical structure under the action of drugs." Su Yun pondered.

Zheng Ren looked up and just Su Yun.

"What do you think of me?"

"Do you remember how you and Lao Fanxue tried hard?" Zheng Ren asked.

"Of course." Su Yun looked at Zheng Ren in confusion, "If you want such a special press? I'll go! Boss, I can barely do it, I can't hold on for too long!"

Zheng Ren was very pleased to hear Su Yun say this.

"Boss Zheng, I can do it!" Lin Yuan said.

"Don't talk nonsense, what can your little arms and legs do?" Su Yun habitually retorted.

"What can't be done when cardiopulmonary resuscitation is passed through the diaphragm!" Lin Yuan said angrily.

"Tell me how to do it."

"The right hand extends the diaphragm from the surgical incision, puts 2-5 fingers together and place them on the diaphragm at the back and lower part of the heart, and place the left palm at 1/3 of the middle and lower part of the sternum to fix it. Use the right elbow, wrist and shoulder joint to coordinate movement to drive the 2-5 palm fingers of the right hand to lift and squeeze to the sternum rhythmically, so that the diaphragm is moved up by 4-5m, and then quickly relax and the diaphragm returns to its original position." Lin Yuan said skillfully.

"Tsk tsk." Su Yun looked contemptuous.

"What?" Lin Yuan raised his head and shook his ponytail.

"The basic theory is very solid." Su Yun said, "This is not critical. If it really doesn't work, I can press it directly with my chest open and look directly. The question is how long can you last for the frequency of 100-120 presses per minute?"

"..." Lin Yuan was speechless.

This is physical work, just like carrying a thigh through orthopedic surgery.

It doesn't sound difficult. Ordinary people have also had contact with external heart compressions, and a few minutes of high frequency compression can still be maintained.

But it is not certain whether the action is right or not.

But that is a routine external chest heart compression, not a cardioresuscitation surgery that is lifted and squeezed through the diaphragm muscle. This kind of unconventional compression requires the right and left hands to cooperate with each other, and the posture is strange and difficult to struggle.

But, this is not the most critical.

Because the patient is in critical condition, the operation course must be shortened and the normal physiological and anatomical structure must be restored.

Heart compression should be performed simultaneously with the anastomotic blood vessels.

The right hand is under the diaphragm, and the surgeon also needs to anastomoses the blood vessels. It must be strong and not only prevent the patient from moving the entire body.

The difficulty can be imagined.

With Su Yunzai, Zheng Ren felt that the operation should be taken down. If you think about it carefully, there seemed to be no deviation.

"I will do it as soon as possible." Zheng Ren said solemnly.

"It's okay." Su Yun smiled, "The chest opening device must be prepared. I'll call Zhao Yunlong to come together. Once I... your surgery takes a long time, maybe you have to open your chest."

"Yes." Zheng Ren nodded.
Chapter completed!
