Zheng Ren glanced at Su Yun and asked, "I want to think about whether there is any other way. Just keep an eye on the letter and reply."
Su Yun nodded.
This is the only thing that can be done. In addition, there are many troubles. As a small branch unit of 912, the medical team is like a spare part and cannot play a big role.
Lin Ge said, "Boss Zheng, I'm going to get busy. I have to report this matter to the hospital and wait for the dean's instructions."
Several people went their separate ways.
Returning to the interventional department, Zheng Ren didn't say a word. He sat in a familiar position, picked up the fifth edition of surgery, and began to face each other.
Seeing Boss Zheng's gloomy face, Lin Yuan didn't say a word and kept his head down as he worked. Gu Xiaoran had just arrived today, and everything was familiar. He had just been scolded by Chang Yue, but he still didn't dare to speak.
"Boss, I still don't believe it." Su Yun glanced at the mailbox and said.
Zheng Ren felt that it should be confirmed by that side, but it was more likely that the email hadn't been sent yet. Big pig hooves generally wouldn't have problems with this kind of thing.
Or maybe it’s not that there are a few overseas lines that can provide liver sources, but that there is a liver source somewhere in China, and we are contacting the 912 hospital.
In short, let’s take a look at the system space first.
He closed his eyes slightly and entered the system space.
Clicking to purchase surgical training time, Zheng Ren strode in as the system operating room rose from the ground.
There are experimental subjects in the operating room, not empty!
Zheng Ren was shocked. This meant that no matter what source of liver it was, there was still liver available.
Then let's start the surgical training. Zheng Ren took a deep breath and prepared to start the operation.
Liver transplantation itself is not a particularly difficult operation. Compared with the donor liver source, surgery becomes a detail.
Standing in front of the operating table, Zheng Ren was calm and composed. The lancet in his hand seemed a little lighter, and he was filled with joy.
The core of liver transplantation, the most difficult time and the most dangerous time for the patient, is the time when the original liver is removed and the new liver is brought in for anastomosis.
This period is called the "anhepatic period", also known as the dark period.
Unlike kidney transplant or lung transplant, there is only one liver. Removing the original liver, even if it is no longer healthy due to acute liver failure, will significantly change the original physiological anatomical pattern, resulting in certain changes in the human body.
In the anhepatic stage, blood from the lower body and gastrointestinal tract of patients cannot flow back to the heart and is in a state of stasis. At this time, the patient's blood volume returning to the heart is reduced and vital signs fluctuate greatly. This is a period of special concern for the operator and anesthesiologist during the entire liver transplant operation.
In addition, the patient Chen Li already had massive bilateral pleural effusion, atelectasis, heart failure, and respiratory failure, so the possibility of cardiac arrest during the operation was particularly high.
The difficulty of emergency surgery is several times higher than that of emergency surgery, even a geometric order of magnitude higher.
Otherwise Zheng Ren wouldn't be desperately trying to get a liver source that matches his blood type and matching type. Only in this way can the patient's fragile body be affected as much as possible.
However, Zheng Ren didn't care too much. He had enough time for surgical training, he was also a master-level surgeon, and he also had the specialization bonus of organ transplantation. Coupled with the halo of luck, he really didn't believe that he couldn't complete the operation!
From the skin opening, layer by layer incision, blunt dissection, peritoneal protection, and opening of the abdominal cavity, Zheng Ren felt that his operation was smooth and smooth.
Zheng Ren felt extremely happy.
In the past, when explaining the condition to patients’ families, they would occasionally say that it would be good if they could undergo surgery. If the disease is too severe to allow surgery, that's the end of it.
But this time, Zheng Ren truly felt the joy of having the surgery.
Entering the abdominal cavity, Zheng Ren first freed the left and right hepatic ligaments and severed the left triangular ligament of the liver. After separating the left and right livers and turning the liver upward, the first porta hepatis is exposed, and the proper hepatic artery, main portal vein and common bile duct are ligated and severed respectively.
Turn the left liver to the right to expose the third porta hepatis, ligate several isolated short hepatic veins, and finally separate the left hepatic vein and the right midhepatic vein, and resect the diseased liver.
Excision is very simple.
It is always easier to destroy than to build. This has been a fact since ancient times.
Zheng Ren's surgery was more detailed. Even if it were done by a novice who had never done a liver transplant, simply cutting the liver would only require ligating and cutting off the blood vessels and ligaments one by one.
Although Zheng Ren's surgery would not be as detailed and clean as that of Zheng Ren, there is no problem in cutting it off.
After cutting the liver, 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 sounds simple, 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, anastomosis and reconstruction of the liver's accessory ducts, including the portal vein, suprahepatic inferior vena cava, infrahepatic inferior vena cava, hepatic artery, and biliary tract, must be completed.
Among them, the anastomosis from the portal vein, suprahepatic inferior vena cava, and infrahepatic inferior vena cava of the diseased liver to the new liver and the patient's portal vein, suprahepatic inferior vena cava, and infrahepatic inferior vena cava is completed and the blood flow is opened. The speed is likely to determine the patient's life and death.
This is the so-called liver-free period.
Zheng Ren is confident in his surgical techniques.
Start rebuilding various pipes.
The Zeiss microscope and various surgical instruments given to Zheng Ren by Dr. Charles played a huge role.
However…
But…
It's of no use.
At 10′22″ of the anhepatic period, the subject’s heart stopped.
Zheng Ren was stunned for a moment. Instead of performing cardiopulmonary resuscitation on the experimental subject, he stood in front of the system operating table and began to ponder his own surgical procedure.
The whole process was correct. Even if I tried it again, I couldn't seem to shorten the liver-free period to less than 10 minutes.
What's the world record? It seems to be about 26 minutes, which is documented. As for this record, Zheng Ren recalled that it should have been mentioned in a case report published in The Lancet magazine three years ago.
Under normal circumstances, in surgical liver transplantation, the anhepatic period should be 30-40 minutes, and this is performed by top surgeons.
Although it is not as remembered by the general public as the Olympic world record, any surgeon who can perform surgery will know how long the shortest liver-free period is.
This is a true technical competition.
But this little patient named Chen Li only gave the surgeon a little more than 10 minutes to perform the anhepatic surgery...
Zheng Ren stared blankly at the system operating room and the experimental subjects on the operating table, feeling a little troubled.
Before, I was confident that the surgery would be successful.
Master-level general surgery skills, expertise in organ transplantation, and a halo of luck...
But all this is not enough!
Why is it only for such a short time? Even if cardiac compressions are added, he will still have to face the impact of restoring blood supply to the portal veins, and face... countless tests.
And cardiac compressions will never allow patients to persist for such a long time.
Zheng Ren was a little crazy.
