The diagnosis given by Sun Lien was a disfigured injury to his right arm. This diagnosis is usually only seen in people who are about to have their limbs amputated.

Zheng Xin's right arm was obviously wrenched into some kind of rotating machine, and it was not a sharp instrument like a meat grinder. Judging by the large number of skin defects and stains on the scars, Sun felt more like his right arm was being wrenched into some kind of heavy pressure machine, such as a large machine like a roller press with feed teeth. The arm has almost no restorative value.

Aside from the fact that during the repair process, the patient will inevitably continue to bleed and eventually die due to excessive blood loss. Even if the blood bank of the Fourth Hospital is connected to some four-dimensional space, which can provide unlimited blood products, a large amount of blood loss followed by a large amount of blood transfusion, DIC and acidosis, electrolyte imbalance, and other difficulties are still waiting for us.

Even if all of the above problems could be solved, repairing such an arm would still be an extremely difficult project.

If Zheng Xin's right arm is really to be repaired, the biggest difficulty is not the small radial head defect and up to 40% of the skin defect. It's the destruction of those four nerves.

Defects in blood vessels can be made up by transplanting other parts of the blood vessels or artificial blood vessels. But there is no way to repair the damage to the nerve -- modern medicine can't even make a working ligament, let alone connect it directly to the nerve used? If the defect is not very long, you can actually pull the nerve at both ends a little, and then try to connect the two ends under the microscope to "see the effect". It may or may not work, and it may also cause severe pain and other sequelae. But at least there's a way to "give it a try".

But all four nerves were destroyed...... There's no point in even giving it a try. If you ignore the nerves and only repair the broken muscles, blood vessels and skin, the patient will end up with nothing more than a prosthesis that can heat up on its own. It would not improve his quality of life, but it would also cost him a lot of money and a long and painful and meaningless period of recovery.

Rather than that, it is safer to amputate the limb altogether. According to visual inspection, Sun Lien estimated that the amputation would preserve at least four to five centimeters of the humerus of Zheng Xin's lower right upper arm. The remaining part of the stump with a suitable prosthesis should allow Zheng Xin to recover to the level of self-care ability within a month or two.

Sun Lien's judgment was very direct, and Dr. Cao Yanhua, who came later, also agreed with Sun Lien's judgment.

"This has to be amputated, and it has to be done as soon as possible. With wet hair and a pale face, Dr. Cao Yanhua lowered his head to examine Zheng Xin's wound, and then shook his head regretfully, "It is impossible to save the limb, if you want to save the limb from this injury, you have to pay for his life." ”

Zheng Xin arrived at the hospital with his wife in the car. When Sun Lien went to talk to the family with the notice, he heard the cause and effect of the accident.

Zheng Xin is a young man from a poor family but willing to work hard. At the age of sixteen, Zheng Xin began to work outside the home, and Zheng Xin has engaged in a variety of occupations in factories around the world. At the age of 20, after saving 100,000 yuan, he decided to fight for his dream - with this 100,000 yuan of principal, as well as the financial support of his parents and parents-in-law, he opened a small metal processing factory.

His own factory is small, and Zheng Xin is one of those rare talents — he is not highly educated, but he is highly skilled. With the advantage of diligence and sweet mouth, he quickly mastered the advanced skills of various metal processing skills in the past four years of his part-time career.

Large metal processing factories have relatively high requirements for orders, and unless the quantity reaches a certain magnitude, there is no interest in connecting orders. But Zheng Xin has a great vision to decentralize the business needs to the standard of five things. Although the cost per piece is much more expensive than that of large processing plants, this business model still brings a very considerable number of orders to his small factory.

And this production accident is also a direct consequence of this business model.

Small factories mean that it is impossible to support too many technical backbones, and a large number of orders for small factories not only means revenue, but also means delivery pressure - most of these processing contracts are signed with compensation clauses. If it can't be delivered in time, the compensation clause alone can directly crush this small processing plant that has just been on the right track.

Since entering June, Zheng Xin's daily sleep time has been compressed by him to less than three hours a day. Today was the last day of delivery, and after completing the processing of the last component, he went straight to the black and fell down at the feed port of the rolling mill.

The moment she learned that her husband was going to have her leg amputated, Zheng Xin's wife was devastated.

She herself is not a person who has seen a big scene, and she met Zheng Xin in a metal processing factory in Shandong - Zheng Xin was a worker in a hot processing workshop at that time, and she was a cook in the canteen. Later, Zheng Xin bought her current belongings little by little, but she actually didn't contribute much to it, Zheng Xin is a special "machismo". He insisted that it should be a man's prerogative to suffer and suffer. No matter how busy he is at work, he will not let his wife play.

At four o'clock in the morning, Zheng Xin was lying in the emergency room in critical condition, and the blood on his body was almost empty. His medical decision-making agent, his wife, has never been able to make the decision to "agree to amputation". She even cried and sent a voice message in the WeChat group, but she couldn't give Sun Lien a clear answer directly - whether you plan to risk your husband's death to save your limbs, or take his life as the first priority and decisively amputate your leg.

Looking at the crying appearance of the family members, Sun Lien was also very anxious. Zheng Xin's blood group rapid test results have come out, and now he is being reheated and pressurized blood transfusion in the emergency room - the two heaters in the rescue room are not enough, in order to rewarm the blood bag as soon as possible, almost all the doctors and nurses who are available at hand are involved. Two blood bags per person, placed under their armpits and in the palms of their hands, are desperately trying to prewarm – which reduces the working time of the heater a little bit. At Zheng Xin's bedside, three nurses were holding blood bags and squeezing the rewarmed blood into Zheng Xin's body through the venous channel. On the ground on the side, there were messy blood bags that had been transfused.

Within 20 minutes of being admitted to the hospital, the Fourth Hospital had already transfused 1,800 milliliters of blood for Zheng Xin. But his heart rate remained at 135.

It's not the way to go. Sun Lien anxiously asked Zheng Xin's wife again, but she still hesitated and said, "Ask the family's opinion again." ”

Sun Lien stomped his feet anxiously, but he couldn't get angry at the patient's family. After thinking about it, he still sighed, tried to calm his mind and persuaded him, "Do you want a living husband, or do you want a corpse with an arm still left?"
