Chapter 2117

Zheng Ren glanced at Su Yun and asked, "I wonder if there is any other way. You stare at the letter."

Su Yun nodded.

This is also the only thing that can be done. In addition, there are many troubles. As a small branch of 912, the medical group is like a part, which can't play much role.

Linge said, "boss Zheng, I'll be busy. I'll report this to the hospital and wait for the dean's instructions."

Several people separated.

Back in the interventional department, Zheng Ren didn't say a word. He was in a familiar position, picked up the fifth edition of surgery and began to meet.

Seeing boss Zheng's gloomy face, Lin Yuan didn't say a word and bowed his head to work. Gu Xiaoran just came here today. Everything is familiar. He has just been scolded by Chang yuexun. He is also afraid to speak.

"Boss, I haven't heard from you yet." Su Yun glanced at the mailbox and said.

Zheng Ren thinks that it should be determined, but it's possible that he hasn't sent an email. Big pig hooves generally don't have problems with such things.

Or maybe it's not that several foreign lines can provide liver source, but that there is liver source somewhere in China, which is contacting the 912 hospital.

In short, take a look at the system space first.

He closed his eyes slightly and entered the system space.

Click to buy the operation training time. With the rise of the system operating room, Zheng Ren strides in.

There are experimental objects in the operating room, not empty!

Zheng Ren's spirit was shocked, which means that no matter what channel the liver source is, in short, there is a liver that can be used.

Then start the operation training. Zheng Ren took a deep breath and was ready to start the operation.

Liver transplantation itself is not particularly difficult. Compared with the donor liver source, the operation becomes a trivial matter.

Standing in front of the operating table, Zheng Ren was calm. The lancet in his hand seemed to be a little lighter and full of joy.

The core of liver transplantation is the time when the original liver is removed and the new liver is taken for anastomosis.

This period of time is called "anhepatic period", also known as the dark period.

Unlike kidney transplantation and lung transplantation, there is only one liver. If the original liver is removed, even the liver that can no longer ensure the health of the body because of acute liver failure will greatly change the original physiological and anatomical model, resulting in certain changes in the human body.

In anhepatic stage, the blood in the lower body and gastrointestinal tract cannot flow back to the heart and is in a state of stasis. At this time, the amount of blood in the patient's heart is reduced and the vital signs fluctuate greatly, which is a period of special concern for operators and anesthesiologists in the whole process of liver transplantation.

In addition, Chen Li has a large amount of bilateral pleural effusion, atelectasis, heart failure and respiratory failure, so there is a great possibility of cardiac arrest during the operation.

Emergency surgery is several times more difficult than slow surgery, even an order of geometric magnitude higher.

Otherwise, Zheng Ren would not desperately want a liver source with the same blood type and matching type. Only in this way can it affect the patient's fragile body as much as possible.

However, Zheng Ren doesn't care very much. He has enough operation training time. He is also a master level operator. He also has the specialized bonus of organ transplantation. Coupled with the lucky aura, he really doesn't believe that he can't finish the operation!

Open the skin, cut layer by layer, blunt separation, peritoneal protection, and open the abdominal cavity. Zheng Ren felt that his operation was general.

Zheng Ren felt very happy.

Once upon a time, when I explained my condition to the patient's family, I occasionally said that it was good to have an operation. If you're terminally ill and can't operate, that's all.

This time, Zheng Ren really felt the pleasure of doing surgery.

Entering the abdominal cavity, Zheng Ren first dissociated the left and right hepatic ligaments and severed the left triangular ligament of the liver. After the left and right liver were separated and turned up, the first hepatic portal was exposed, and the proper hepatic artery, main portal vein and common bile duct were ligated and disconnected respectively.

Turn the left half of the liver to the right to expose the third hepatic portal, ligate several short hepatic veins, and finally disconnect the left hepatic vein and the right middle hepatic vein to remove the diseased liver.

Excision is very simple.

Destruction is always easier than construction. It has been a fact since ancient times.

Zheng Ren's operation is more meticulous. Even if he has not done liver transplantation, it is enough to simply cut off the liver by ligating and cutting off blood vessels and ligaments.

Although Zheng Ren's operation will not be so meticulous and clean, it is no problem to cut it off.

After cutting off the liver, Zheng Ren picked up the right lobe of the donor liver next to him and prepared to complete various pipeline reconstruction for liver transplantation.

It's simple, but that's compared to finding a donor.

In fact, the whole process is still complicated.

After the new liver enters the recipient's abdominal cavity, the anastomosis and reconstruction of liver accessory ducts should be completed, including portal vein, superior and inferior hepatic vena cava, inferior hepatic vena cava, hepatic artery and biliary tract.

From the portal vein, superior and inferior hepatic vena cava and inferior hepatic vena cava of the diseased liver to the anastomosis of the new liver and the patient's portal vein, superior and inferior hepatic vena cava and inferior hepatic vena, the blood flow is completed and opened. The speed is likely to determine the patient's life and death.

This is the so-called anhepatic period.

Zheng Ren has confidence in his surgical technique.

Start rebuilding various pipelines.

Zeiss's microscope and various surgical instruments given to Zheng Ren by Dr. Charles played a great role.

However

But

No eggs.

At the 10th ′ 22 ″ of anhepatic phase, the heart stopped suddenly.

Zheng renleng thought for a moment. Instead of CPR for the experimental body, he stood in front of the system operating table and began to think about his own operation process.

The whole process is correct. Even if I do it again, I don't seem to be able to shorten the anhepatic period to less than 10 minutes.

What's the world record again? It seems to be about 26 minutes, which is recorded. Zheng Ren recalled that this record should have been mentioned in a case report published in the lancet magazine three years ago.

In general, the anhepatic period of surgical liver transplantation should be 30-40 minutes, which is still the main operation of top surgeons.

Although it is not like the world record of the Olympic Games and is remembered by the broad masses of the people, those who can perform surgery will know how long the shortest anhepatic period is.

This is a real competition in the field of technology.

But this little patient named Chen Li only gave the operator a little more than 10 minutes to perform the anhepatic operation

Zheng Ren looked at the system operating room and the experimental body of the operating table. He was a little distressed.

I was confident that the operation would be taken down.

Master level general surgery skills, organ transplantation expertise, and a lucky aura

But all this is not enough!

Why is there such a short time? Even with cardiac compression, we have to face the impact of restoring blood supply to the portal vein and... Countless tests.

And cardiac compression, absolutely can't let the patient persist for so long.

Zheng Ren is a little crazy.
