Chapter 2116 Unable to Complete the Operation

Zheng Ren glanced at Su Yun, and asked, "I wonder if there is any other way, just keep an eye on the letter."

Su Yun nodded.

This is also the only thing that can be done. Apart from this, there are many troublesome things. As a small branch of 912, the medical team is like a part and cannot play much role.

Linge said, "Boss Zheng, I'll go to work then. I need to report this matter to the courtyard and wait for the dean's instructions."

Several people parted ways.

Returning to the interventional department, Zheng Ren didn't say a word, took the familiar position, picked up the fifth edition of surgery, and started to meet each other.

Seeing Boss Zheng's gloomy face, Lin Yuan didn't say a word, just lowered his head to work. Gu Xiaoran just came here today, everything is familiar to him, he was just reprimanded by Chang Yue, but he also dare not speak.

"Boss, I haven't believed it yet." Su Yun glanced at the mailbox and said.

Zheng Ren felt that it should be determined on that side, but it is more likely that the email has not been sent yet, and big pigs usually don't have problems with this kind of thing.

Or maybe it's not that several foreign lines can provide liver sources, but that there is a liver source somewhere in China, and they are 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 surgery training time, and as the system operating room rises, Zheng Ren strides in.

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

Zheng Ren's spirit was shaken, which meant that no matter what source of liver was obtained, there was still liver available.

Then start the surgery training, Zheng Ren took a deep breath, ready to start the surgery.

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 calmed down, the lancet in his hand seemed to be a little lighter, and there was a burst of joy.

The core of liver transplantation, the most difficult and the most dangerous time for patients, lies in the time when the original liver is removed and the new liver is brought in for anastomosis.

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

Unlike kidney transplants and lung transplants, there is only one liver. The original liver is cut away, even if the liver can no longer guarantee the health of the body due to acute liver failure, the original physiological and anatomical model will be greatly changed, resulting in certain changes in the human body.

In the anhepatic stage, blood from the lower body and gastrointestinal tract of patients cannot return to the heart, and they are in a state of stasis. At this time, the amount of blood returning to the heart decreases and the vital signs fluctuate greatly. This is a period of special concern for surgeons and anesthesiologists during the entire liver transplant operation.

In addition, the patient Chen Li already had a large amount of bilateral pleural effusion, atelectasis, heart failure, and respiratory failure, so the possibility of cardiac arrest during the operation was particularly high.

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

Otherwise, Zheng Ren would not desperately want a liver source with matching blood type and matching type. Only in this way can the fragile body of the patient be affected as much as possible.

However, Zheng Ren didn't care too much. There was enough time for surgery training, and he was also a master-level surgeon. With the bonus of specialization in organ transplantation, and the halo of luck, he really didn't believe that the surgery could not be completed!

Opening the skin, incision layer by layer, blunt dissection, peritoneal protection, and opening the abdominal cavity, Zheng Ren felt that his operation was smooth and smooth.

Zheng Ren felt extremely happy in his heart.

When explaining the condition to the patient's family members, I occasionally said that it is good to have surgery. If the disease is terminally ill and there is no way to do surgery, that's all.

But this time, Zheng Ren really felt the joy of being able to perform surgery.

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

The left hemi-liver was turned to the right to expose the third hepatic hilum, and several short hepatic veins were ligated and separated. Finally, the left hepatic vein and the right hepatic vein in the liver were cut off, and the diseased liver was resected.

Excision is very simple.

It is always easier to destroy than to build. This has been a fact since ancient times.

Zheng Ren's operation was relatively meticulous. Even if it was done by a novice who had never done a liver transplant, simply cutting the liver would be enough to ligate and cut off the blood vessels and ligaments one by one.

Although it won't be as meticulous and clean as Zheng Ren's surgery, it's okay to cut it off.

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

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

In fact, the whole process is quite complicated.

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

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

This is the so-called anhepatic phase.

Zheng Ren had confidence in his surgical techniques.

Start rebuilding various plumbing.

The Zeiss microscope and various surgical instruments given to Zheng Ren by Dr. Charles played a huge role.

However……

But……

It's useless.

At the 10′22″ of the anhepatic period, the subject suffered cardiac arrest.

Zheng Ren was stunned for a moment. Instead of performing CPR on the experimental subject, he stood in front of the operating table of the system and began to think about his own operation process.

The whole process was correct, even if I did it again, it seemed that I couldn't shorten the anhepatic period to less than 10 minutes.

What is the world record? It seems to be around 26 minutes, which is documented. Zheng Ren recalled that this record should have been mentioned in a case report published in The Lancet 3 years ago.

Under normal circumstances, in surgical liver transplantation, the time of anhepatic period should be 30-40 minutes, which is performed by top surgeons.

Although it is not remembered by the general public like the world record in the Olympic Games, any surgeon who can perform surgery will know how long the shortest anhepatic period is.

This is a competition in the real technical field.

However, this little patient named Chen Li only gave the surgeon a little more than 10 minutes to perform the operation in the anhepatic period...

Zheng Ren stared blankly at the system operating room and the experimental subjects on the operating table, feeling a little distressed.

Before, I was confident that the surgery would be successful.

Master-level general surgery skills, specialization in organ transplantation, shrouded in a halo of luck...

But all this is not enough!

Why only for such a short time? Even with heart compressions, he still has to face the shock of restoring the blood supply of the portal vein, and also faces... countless tests.

Cardiac compressions absolutely cannot allow patients to persist for such a long time.

Zheng Ren was a little crazy.
