Lu Zewei smiled awkwardly, but as Su Yun lowered his head, his expression gradually became serious.
Osteofascial compartment syndrome, open decompression? It was already necrotic. How was he supposed to reduce the pressure?
Although he was not in the orthopedics department, Lu Zewei still understood the most basic knowledge.
The surgeon then made a 20cm incision on the outside of the right calf to cut through the skin and subcutaneous tissue.
When the fascia of the lateral and anterolateral compartment was opened, the tension in the fascia was high and the muscles were necrotic.
The surgeon sighed and began to remove the necrotic tissue.
"Boss, how much will my motor function be affected?" Su Yun suddenly asked.
"It's a lot, but it's better than amputation," Zheng Ren replied. "Being able to keep one leg is already considered a relatively light injury. Do more functional exercises after the surgery, and the other muscles may be able to compensate for part of their functions. "
Lu Zewei was dumbfounded.
It was not because of the removal of the entire muscle. This type of surgery was rare, but it was definitely not unheard of.
He was a little dumbfounded because he heard Su Yun address the young man in front of him as boss.
Such a young boss? Furthermore, he was from the Orthopedics Department. What could he do to make Su Yun, who had always been noisy and sarcastic, behave?
The surgeon was talking to Su Yun, but his hands did not slow down at all.
He explored the surgical area and saw that the contusion of the anterior tibial artery thinned at the level of the tibia and fibula fracture. The distal pulsation was obviously weakened, but the proximal pulsation was normal. The superficial peroneal nerve was continuous. He gave warm saline wet compress and then explored the posterior tibial artery. The proximal pulsation recovered at the level of the tibia and fibula fracture.
Zheng Ren heaved a sigh of relief.
"It's finally open. The embolization time is still relatively short. If it were a few more hours, I'm afraid it wouldn't work."
Su Yun smiled and did not say anything.
Zheng Ren looked for the anesthesiologist to take a look at the foot. The anesthesiologist was also very excited. He quickly walked around Lu Zewei, opened the warm saline gauze, and used his hand to measure the patient's foot.
"The dorsal artery of the foot is fluctuating!" the anesthesiologist said excitedly.
"That's completely activated." Zheng Ren was also very happy. He asked, "VSD negative pressure attraction, right?"
"Yes."
"We'll see what happens after the surgery. If there's a problem with the decompression opening …"
"Boss, you're so long-winded. This is Chengdu Provincial Hospital. You don't have to worry about the most basic operations, "Su Yun looked up at Zheng Ren and said.
The recovery of the arteries meant many things. The simplest was that the patient who was carried down did not need to be amputated for the time being.
The reason why it was temporary was that there was necrotic tissue in the local area. In addition to the osteofascial compartment syndrome, it was hard to say whether the muscles, blood vessels, and nerves would survive.
The rest would depend on the subsequent treatment methods. Among them, the VSD decompression technology is this one.
VSD technology, also known as vacuum sealing drainage technology.
Negative pressure acted on the cell membrane, causing it to expand and distort. The cell would think that it was injured and transmit the information of the injury to the cell nucleus. Through signal conversion, the cell would secrete prehealing growth factors, including vascular proliferation factors, thereby stimulating the tissue to produce more new blood vessels.
Moreover, it could effectively reduce the possibility of postoperative infection.
For the patient lying on the operating table, without the VSD decompression equipment, the possibility of saving his calf was less than 10%. However, with the VSD decompression equipment, there was an 80% chance that the calf could be saved.
"Hehe." Zheng Ren was already immune to Su Yun's words and just chuckled.
"Boss, speaking of VSD, do you know of any other uses?" Su Yun suddenly asked.
At this moment, all the problems were easily solved. Zheng Ren was also very happy, so he smiled and said, "Is it the effect of negative pressure attraction on ED treatment? I don't think it's reliable. Although there are related reports in all kinds of literature, the amount of data is not enough. I'm skeptical about this. "
"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 soon, so there's no hurry."
Uh … Lu Zewei saw that Su Yun had been defeated and was secretly pleased.
Back then, he could not talk back in front of Su Yun. It was not because this guy read all kinds of books. In addition, his skill level was high, and he was very picky.
He could not talk back because his skills were not as good as others.
Lu Zewei was secretly pleased for a few seconds, but on second thought, he was stunned.
Faced with Su Yun's provocation, the surgeon in front of him easily resolved it. How could he do it? It was because the surgeon knew what Su Yun was going to say the moment he opened his mouth.
This was a crushing of knowledge. Although it was not as direct as the crushing of skill, from the side …
This surgeon seemed to be very powerful.
Yes, it seemed. Lu Zewei was not very sure.
He looked at the surgeon in a daze as he cut open the dorsum of the foot for the injured person to decompress. The surgeon touched the dorsum of the foot artery and said, "The fluctuations are fine. I want to do an image to see."
"Boss, this doesn't seem like your style." Su Yun had just suffered a loss silently. He grabbed Zheng Ren's words and wanted to retort.
"Yes, embolization is a destructive surgery. I'm more supportive. However, I always want to see the results of the opening of the capillaries during the opening surgery, "Zheng Ren said lightly.
Lu Zewei was a little confused. Seeing the surgeon and Su Yun start to scrub their hands again, he still did not understand why.
"Old Lu, let's go out and take a look." The anesthesiologist pulled Lu Zewei out of the operating theater.
"This is … What kind of surgery is this?" Lu Zewei still did not understand.
"Old Lu, I've seen an expert today." The light in the anesthesiologist's eyes was a little dazzling.
"Huh?" Lu Zewei still did not understand why he was so excited. Seeing that the scrub nurse had also walked out, she closed the airtight lead door and quietly listened to the anesthesiologist.
"Old Lu, this injured person is a volunteer who went into the mountain," the anesthesiologist said. "When he was withdrawn, a rock hit his lower leg, causing a fracture. He was pressed for more than an hour. Because the follow-up personnel arrived in time, the crushing injury and necrosis were not too serious. "
"But that should have been amputated, right?" Lu Zewei was a little puzzled.
"This is the awesome part," the anesthesiologist said proudly as if he was the one who performed the surgery. The anesthesiologist said proudly as if he was the one who performed the surgery. "The wounded were sent here just now, and Chief Chen sent them up."
"Which Chief Chen?"
"The retired chief of the Department of Interventional Medicine. You haven't seen him before. The old man has a very stubborn temper. " The anesthesiologist did not forget to comment on Chief Chen's temper. Then, he continued, "Chief Chen said that these volunteers were here to help us. If they could not amputate, they would not amputate. I thought it was just a wish and did not take it seriously. But who would have thought that the surgeon who performed the surgery would agree and start the surgery? "
"I saw it. Is the fracture fixed?"
"What you saw was the second half," the anesthesiologist said. "The really exciting part was the first half of the surgery."
