Chapter 731: Crushing Knowledge

Lu Zewei smiled awkwardly but as Su Yun lowered his head, his expression gradually became serious.

Osteofascial compartment syndrome and decompression? The necrosis was already in its last stages so how could he reduce the pressure?

Although he was not in the orthopedics department, Lu Zewei still understood the most basic of medical problems.

The surgeon took another 20cm long vertical incision on the outer side of the right calf and cut open the skin and subcutaneous tissue.

When he opened the fascia of the lateral and anterolateral compartment, he saw that the tension in the fascia was higher and the muscle had been striated.

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

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

“By quite a bit. However, it’s still better than complete amputation,” Zheng Ren answered. “To be able to save one leg is already considered a relatively light injury. After the surgery, they just need to do more functional exercises so that the other muscles can get used to compensating for some of the other functions.”

Lu Zewei was dumbfounded.

It was not because of the whole muscle resection. This kind of surgery was rare but was definitely not unheard of.

He was a little dumbfounded because he heard Su Yun call the young man in front of him ‘boss’.

There was such a young boss? And he was also in the orthopedics department. What could he do to make the always noisy and sarcastic Su Yun behave?

The surgeon and Su Yun were talking, but their speed had not even slowed down in the slightest.

He probed the area of the technique and saw that the injury level of the anterior tibial artery on the tibia and fibula fracture had become thinner. The far-side pulsation was obviously weakened. The near-side pulsation was normal, and the superficial peroneal nerve was intact. He gave a warm saline wet compress and then checked the posterior tibial artery. The near-side pulsation on the level of the tibia and fibula fracture had recovered.

Zheng Ren finally let out a long breath he had been holding.

“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 didn’t say anything.

Zheng Ren asked 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 injured person’s foot.

“The dorsalis pedis artery is fluctuating!” the anesthesiologist said excitedly.

“Then it’s completely opened.” Zheng Ren was also very happy. He asked, “Is there any problem with the VSD suction of negative pressure?”

“Yes.”

“After the operation, things will be dependent on the situation. If there’s a problem with the decompression incision...”

“Boss, you’re very long-winded. This is Chengdu Provincial Hospital. You don’t have to worry about the most basic operation,” Su Yun said as he raised his head to look at Zheng Ren.

The recovery of the arterial fluctuations meant a lot of things. The simplest thing was that the injured person who was carried down could temporarily avoid amputation.

The reason why it was temporary was because there was necrotic tissue in the local area. In addition to the compartment syndrome, it was hard to say whether the muscles, blood vessels, and nerves could survive.

The rest would depend on the subsequent treatment methods. Among them, VSD decompression technology was one of them.

VSD technology, also known as vacuum sealing drainage technology.

Negative pressure was attracted to the cell membrane, making it expand and distort. The damaged cells would then transmit information to the nucleus through signal conversion, causing the cell to secrete pre-healing growth factors, including vascular proliferation factors. This would then stimulate the tissue to produce more new blood vessels.

Moreover, it could effectively reduce the possibility of infection after the operation.

For the patient lying on the operating table, without the VSD decompression equipment, the probability of his calf being saved was less than 10%. However, with the VSD decompression equipment, there was an 80% chance of it going the other way.

“Hehe.” Zheng Ren was already immune to Su Yun’s words. He just chuckled.

“Boss, speaking of VSD decompression, do you know of any other uses?” Su Yun suddenly asked.

At this moment, all the problems had been solved. Zheng Ren was also very happy, so he smiled and said, “Is there an effect of negative pressure on ED treatment? I think it’s quite unreliable. Although there are relevant reports in all kinds of literature, there’s not enough data on it so I’m still skeptical.”

“You even know this?” Su Yun was surprised.

“When I studied VSD to reduce stress, I read relevant literature reports.” Zheng Ren said, “If you want, there will probably be technical improvements soon so there’s no rush.”

Uh... Lu Zewei saw that Su Yun was defeated and was secretly happy.

Back then, he kept not being able to talk in front of Su Yun. It was not because this guy read all kinds of books. Besides being skilled, he was also quite picky with the topics he chose to talk about.

He could not talk back because his skill was not as good as Su Yun’s.

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

Facing Su Yun’s provocation, the wizard in front of him had easily resolved it. How did he do it? It was because when Su Yun opened his mouth, the surgeon knew what he was going to say next.

This showed his crushing knowledge reserves. Although it was not as direct as having overwhelming skill, but from the side...

This surgeon seemed to be very powerful.

Yes, that seemed to be the case. Lu Zewei was still not very sure.

He looked at the surgeon in a daze as he performed another incision on the back of the foot to reduce the pressure on the injured patient. The surgeon touched the back of the foot artery and said, “The fluctuation is still okay. I want to make an image to take a look.”

“Boss, this doesn’t seem like your style.” Su Yun had just silently suffered a loss. He grabbed Zheng Ren’s words and wanted to retort.

“Yes, embolization is a destructive surgery. I’m usually quite confident but when I do a surgery, I always think about seeing the results after opening the capillaries,” Zheng Ren said lightly.

Lu Zewei was a little confused. When he saw the surgeon and Su Yun start to brush 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.

“What... What kind of surgery is this?” Lu Zewei still hadn’t figured it out.

“Old Lu, we’ve met a master today.” The light in the anesthesiologist’s eyes was a little dazzling.

“Ah?” Lu Zewei still didn’t understand why he was so excited. Seeing that the scrub nurse had also walked out and closed the airtight lead door, he quietly listened to the anesthesiologist’s words.

“Old Lu, this patient was a volunteer who entered the mountain,” the anesthesiologist said. “When he was evacuated, he was hit by a rock on his calf, causing a fracture. He was crushed by the rock for more than an hour. Because the follow-up staff arrived in time, the impact injury and necrosis were not too serious.”

“But he should have amputated his leg, right?” Lu Zewei was a little puzzled.

“This is what makes it awesome,” the anesthesiologist said proudly as if he was the one who performed the surgery. “Just now, when the injured were sent here, Chief Chen sent them up.”

“Which Chief Chen?”

“The retired interventional department chief. 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 before he continued, “Chief Chen said that these volunteers are here to help us. If possible, they won’t amputate. I thought it was just a fruitful wish and I didn’t take it seriously. But who would have thought that the surgeon would agree and start the surgery.”

“I saw it. Is the fracture fixed?”

“What you saw was the second half,” the anesthesiologist said. “The truly amazing part is the first half of the surgery.”
