Chapter 730 The Crushing of Knowledge Reserves

Lu Zewei sneered for a while, but as Su Yun lowered his head, his expression gradually became serious.

Compartment syndrome, incision and decompression? Necrosis is complete, how to decompress?

Although he doesn't specialize in orthopedics, Lu Zewei still understands the most basic common sense.

The operator then made a longitudinal incision about 20 cm long on the outer side of the right calf, and cut open the skin and subcutaneous tissue.

The fascia of the lateral and anterolateral compartments was opened, and it was found that the tension in the fascia was high, and the muscle had been necrotic.

The surgeon sighed and began to cut away the necrotic tissue.

"Boss, how much will the motor function be affected?" Su Yun asked suddenly.

"It's big, but it's better than amputation." Zheng Ren replied, "If you can save one leg, the injury is considered relatively minor. If you do more functional exercises after the operation, other muscles may compensate for part of the function."

Lu Zewei was dumbfounded.

It's not because of the removal of the entire muscle. This kind of surgery is rare, but it's definitely not unheard of.

He was a little silly because he heard Su Yun call the young man in front of him - the boss.

Such a young little boss? He is still in orthopedics, what can he do to make Su Yun, who has always been noisy and bitter, calm down.

The operator and Su Yun were talking, but the movements of their hands did not slow down a bit.

He explored the operation area and found that the anterior tibial artery was contused and thinned at the level of the fractured end of the tibia and fibula. The proximal pulsation at the level of the fractured tibia and fibula was restored.

Only then did Zheng Ren heave a sigh of relief.

"It's finally opened, but the embolization time is relatively short. If it takes a few more hours, I'm afraid it won't work."

Su Yun smiled, but did not speak.

Zheng Ren asked the anesthetist to take a look at the foot, and the anesthetist was also very excited. He quickly walked around Lu Zewei, opened the warm saline gauze, and measured the injured person's foot with his hand.

"The dorsalis pedis artery has fluctuated!" the anesthetist said excitedly.

"That's completely opened." Zheng Ren was also very happy, and asked: "VSD negative pressure suction, yes."

"have."

"It depends on the situation after the operation. If there is a problem with the incision of the decompression port..."

"Boss, you are very wordy. This is the Provincial Court, so you don't need to worry about the most basic operations." Su Yun looked up at Zheng Ren and said.

The restoration of fluctuations in the arteries means many things. The simplest is that the wounded person who was carried down can temporarily not have to be amputated.

The reason why it is temporary is because there is necrotic tissue in the local area, plus the compartment syndrome, it is hard to say whether the muscles, blood vessels, and nerves can survive.

The rest depends on the follow-up treatment. Among them, the VSD decompression technology is this one.

VSD technology, also known as vacuum sealing drainage technology.

Negative pressure acts on the cell membrane to expand and distort it. The cell is considered damaged, and the information of damage is transmitted to the nucleus. Through signal conversion, it causes the cell to secrete pre-healing growth factors, including vascular proliferation factors, thereby stimulating the tissue to produce more Neovascularization.

And it can effectively reduce the possibility of postoperative infection.

For the wounded lying on the operating table, without VSD decompression equipment, the possibility of keeping his calf is less than 10%. But with the VSD decompression device, there is an 80% chance of saving the calf.

"Hehe." Facing Su Yun's words, Zheng Ren was already immune, so he just smiled.

"Boss, speaking of VSD decompression, do you know that there are other uses?" Su Yun asked suddenly.

At this time, all the problems were solved, and Zheng Ren was also very happy, so he said with a smile: "Is it the effect of negative pressure suction on ED treatment? I think it is quite unreliable. Although there are related reports in various literatures, the amount of data Not enough, and I'm skeptical about that."

"You even know this?" Su Yun was surprised.

"When I was learning VSD decompression, I read related literature reports." Zheng Ren said: "If you want to do it, there will probably be technical improvements in the near future, so don't worry."

Uh... Lu Zewei felt secretly refreshed when he saw that Su Yun was devastated.

I kept talking in front of Su Yun back then, not because this guy reads all kinds of books, and because he has a high level of technology, he is so sharp to pick and choose faults.

I can't talk anymore because my skills are not as good as people's.

Lu Zewei was secretly happy for a few seconds, but after thinking about it, he was stunned.

Facing Su Yun's provocation, the magician in front of him easily resolved it. Why can people do it? It wasn't because Su Yun opened his mouth that the performer knew what he was going to say later.

This is the crushing of knowledge reserves, although it is not as direct as the crushing of technical level, but from the side...

This performer seems to be very powerful.

Well, it seems that Lu Zewei is not very sure.

He watched in a daze as the operator performed an incision and decompression on the dorsum of the foot. The operator touched the dorsalis pedis artery and said, "The fluctuation is okay. I want to take a picture."

"Boss, this doesn't look like your style." Su Yun just suffered a loss silently, and caught Zheng Ren's words, wanting to fight back.

"Well, embolization is a destructive operation, and I'm more supportive. But in opening surgery, I always think about seeing the results of the opening of the capillaries." Zheng Ren said lightly.

Lu Zewei looked a little confused, and the practitioner and Su Yun started to brush their hands again, but he still didn't understand what it was for.

"Old Lu, let's go out and have a look." The anesthetist pulled Lu Zewei out of the operating room.

"What kind of surgery is this?" Lu Zewei still hasn't figured it out yet.

"Old Lu, I saw an expert today." The light in the anesthesiologist's eyes flickered a bit dazzlingly.

"Ah?" Lu Zewei still doesn't understand why he is so excited. Seeing that the equipment nurse also came out and closed the airtight lead door, he quietly listened to the anesthetist's words.

"Old Lu, the wounded is a volunteer who went into the mountain." The anesthesiologist said: "When I was withdrawing, I was hit by a stone in the calf, causing a fracture, and it was crushed for more than an hour. Because the follow-up personnel arrived in time. , so the crushing injury and necrosis are not too serious."

"But it should also be amputated." Lu Zewei was a little puzzled.

"This is amazing." The anesthetist said proudly, as if he had performed the operation, "Just now when the wounded were delivered, Director Chen sent them here."

"Which Director Chen?"

"The retired old director of the Intervention Department, you haven't seen him before. The old man has a very stubborn temper." The anesthetist did not forget to comment on Director Chen's temper, and then continued: "Old Director Chen said that these volunteers are all Those who come to help us will not amputate their limbs if they don’t. I thought it was just a wish, but I didn’t take it seriously. But who would have thought that the operator who performed the operation would agree to it, and then began to operate.”

"I saw it, is the fracture fixed?"

"What you see is the second half." The anesthesiologist said, "The real wonderful thing is the first half of the operation."
