Chapter 731: Rolling of knowledge reserves

Lu Zewei smiled a little, but as Su Yun bowed his head, his expression gradually became serious.
Osteofascial compartment syndrome, open decompression? Already necrotic is very complete, how to decompress?
Although not engaged in orthopedics, but the most basic common sense Lu Zewei still understands.
The surgeon then took the longitudinal incision of the right lower leg for about 20 cm and cut the skin and subcutaneous tissue.
Open the lateral and anterior medial compartment fascia, see the fascia internal tension is high, the muscle has been necrotic.
The surgeon sighed and began to remove necrotic tissue.
"Boss, how much will the sports function be affected?" Su Yun suddenly asked.
"It's big, but it's better than amputation." Zheng Ren replied, "It can be considered that the leg can be saved. The injury is relatively light. After the operation, the other muscles may compensate for some functions."
Lu Zewei was all stupid.
It is not because of the entire section of muscle resection, this type of surgery is rare, but it is definitely not without.
He was a little stupid because he heard Su Yun call him the young man in front of him - the boss.
Such a young boss? Still orthopedic, he will be able to make Su Yun, who has always been noisy and bitter, honest.
The surgeon and Su Yun are talking, but the movements on the hand are not slow.
He explored the operation area and saw that the anterior tibial artery was constricted at the level of the humeral fracture. The distal pulsation was obviously weakened, the proximal pulsation was normal, and the superficial temporal nerve was intact. The warm saline was applied and the posterior tibial artery was explored. The proximal pulsation of the humeral fracture end was restored.
Zheng Ren has only breathed a sigh of relief.
"It was finally opened, and the time for embolization was relatively short. If it was a few more hours, I wouldn’t be afraid."
Su Yun smiled and didn't speak.
Zheng Ren looked for an anesthesiologist to look at his eyes. The anesthesiologist was also very excited. He quickly bypassed Lu Zewei, opened the warm salt water gauze, and measured the injured person's foot by hand.
"The dorsal artery of the foot has fluctuated!" the anesthesiologist said excitedly.
"That was completely opened." Zheng Ren was also very happy and asked: "VSD negative pressure attraction, yes."
"Have."
"After the postoperative situation, if there is a problem with the decompression opening..."
"Boss, you are very embarrassed. Here is the provincial hospital, the most basic operation does not have to worry about you." Su Yun looked up at Zheng Ren, said.
The recovery of arteries volatility means a lot of things. The simplest thing is that the wounded person who has been lifted down can temporarily not have an amputation.
The reason is temporary because of local necrotic tissue, plus the compartment syndrome, muscles, blood vessels, and nerves can not survive.
The rest, depends on the treatment of the follow-up. Among them, VSD decompression technology is this.
VSD technology, also known as vacuum closed drainage technology.
Negative pressure attraction acts on the cell membrane, causing it to expand and distort. The cells are considered to be damage, and the information of conduction damage is given to the nucleus. Through signal conversion, the cells are caused to secrete pre-growth growth factors, including vascular proliferation factors, thereby stimulating tissue production. New blood vessels.
And it can effectively reduce the possibility of postoperative infection.
For the wounded lying on the operating table, there is no VSD decompression device, and his calf is less than 10%. But with VSD decompression equipment, 80% may hold the calf.
"Oh." In the face of Su Yun, Zheng Ren has already been immune, but hehe smiled.
"Boss, talking about VSD decompression, do you know there are other uses?" Su Yun suddenly asked.
At this point, all the problems were solved. Zheng Ren was also very happy. He smiled and said: "Is negative pressure attraction acting on ED treatment? I feel quite unreliable. Although all kinds of literature have related reports, the amount of data Not enough, I am skeptical about this."
"Do you even know this?" Su Yun was surprised.
"When learning VSD decompression, I have read relevant literature reports." Zheng Rendao: "If you want to do it, it is estimated that there will be technological improvements soon, so don't worry."
Hey... Lu Zewei saw Su Yun eating, and his heart was dark.
In the past, I kept on speaking in front of Su Yun. It was not because of the books of this kind of goods, but also the high level of technology.
I can't speak my mouth because it is not as good as people.
Lu Zewei’s heart was dark for a few seconds, but he thought about it and immediately became stunned.
In the face of Su Yun's provocation, the surgeon in front of his eyes easily resolved. Why can people do it? It's not because Su Yun has a mouth, the surgeon knows what to say later.
This is the crushing of the knowledge reserve, although it is not as direct as the technical level, but from the side...
This surgeon seems to be very powerful.
Well, it seems that Lu Zewei is not very sure.
He looked at the surgeon a little and gave the wounded a cut and decompression of the foot. The surgeon touched the dorsal artery of the foot and said: "The fluctuations are good, I want to make a look."
"Boss, this is not like your style." Su Yun just ate a loss without a sound, grabbed Zheng Ren's words, and wanted to come back.
"Well, embolism is a destructive operation. I compare the bottom. But when I open the operation, I always remember to see the opening result of the capillaries." Zheng Ren said faintly.
Lu Zewei looked a little confused, seeing the surgeon and Su Yun began to brush his hands again, he still did not understand what it was for.
"Lao Lu ~ EbookFREE.me ~ go, go out to see." Anesthesiologist pulled Lu Zewei out of the operating room.
"This is... what surgery is it." Lu Zewei has not yet understood.
"Lao Lu, I can see a tall man today." The radiance in the anesthesiologist's eyes was a bit dazzling.
"Ah?" Lu Zewei still doesn't understand why he is so excited. See the equipment nurse also came out, closed the airtight lead door, and listened to the anesthesiologist quietly.
"Lao Lu, this wounded is a volunteer who went into the mountains." The anesthesiologist said: "When I pulled out, I was hit by a stone in the calf, causing a fracture, and it was pressed for more than an hour. Because the successor arrived in time. Therefore, crushing and necrosis are not too heavy."
"But that should also be amputated." Lu Zewei is somewhat puzzled.
"This is the place of arrogance." The anesthesiologist said smugly, just like the surgery was done by him. "The wounded person was sent, and the director Chen sent it up."
"Which director Chen?"
"The old director of the retired department of the interventional department, you have not seen it. The old man, the temper is very good." The anesthesiologist did not forget to comment on Director Chen's temper, and then continued: "Director Chen said that these volunteers are To help us, I can't amputate without amputation. I thought it was just a wish, and I didn't take it seriously. But whoever thought that the surgeon had promised to go down and started surgery."
"I saw it, is the fracture fixed?"
"What you see is the second half." Anesthesiologist said, "The real excitement is the first half of the operation."
