I Spent Those Years In the Operating Room Fighting Monsters

Li Dongshan raised his head and glanced at Lu Cheng, then only put down the electric knife in his hand.

Knives for surgical instruments can be roughly divided into four categories, round knife cuts the skin, sharp knife cuts the subcutaneous, and blunt separation of the muscle layer. The electrosurgical knife stops bleeding, and the plasma knife makes fine and internal organs.

He said in his heart: Xiao Lu, I know what you mean. The principle of debridement surgery is to use a sharp knife instead of an electrosurgical knife, because the electrosurgical knife has a hemostatic effect and no blood supply can be seen, but like this large area of ​​necrotic tissue , It's the same thing to cut down with a sharp knife.

On the contrary, because the sharp knife is not as dry as an electric knife, the cutting edge will be sticky.

But Lu Chengcheng mentioned it, and he was still his proud student. In particular, the master also yelled Li Dongshan's heart very happy, listening to Lu Cheng didn't hinder anything, at most it just increased the operation time.

The itinerant nurse and Wang Linfeng hurriedly handed the sharp knife to the stage.

Then Li Dongshan prepares to draw in large chunks.

Lu Chengxin said that this was not possible. Lu Cheng just used the dexterous touch he had only obtained before and felt that although the patient's quadriceps muscles appeared to have large areas of necrosis, there was actually a blood supply inside.

However, the blood vessels are very weak. Although the outer muscles are necrotic, the inner muscle fibers are still beating. It is best to keep this part of the muscle fibers.

Lu Cheng silently screwed up the necrotic muscle layer with tweezers, so that it just blocked the path that Li Dongshan was drawing.

Li Dongshan still didn't say much, he just cut open the necrotic muscle that Lu Cheng twisted up, and cut a lot of it into a long strip. The inside was a piece of white fish, so he couldn't die anymore, and the gods estimated that it would be difficult to save.

Then Lu Cheng suggested: "Master, if you don't need an injection needle to come up, try to find the blood supply. The patient has a lot of necrotic tissue, but it can be a little bit more."

Whether there is a blood supply, the most direct way is to pierce it with a needle, but it is a bit difficult to pierce the bleeding on this patient.

The reason for necrosis is that the infiltration of bacteria will swallow blood vessels or the bacteria will block them, leading to necrosis of distant muscles, or the microenvironment of bacteria makes blood supply obstacles.

"Let's go ahead." Li Dongshan shouted, anyway a dead horse would be a living doctor.

Wang Linfeng just breathed a sigh of relief. He was also afraid that Li Dongshan would be angry and made a big deal, but it seemed that the young man brought by Li Dongshan could still persuade him.

Then he gave the syringe needle to Lu Cheng.

Lu Cheng thought for a while, adjusted the angle of the syringe a little, and pierced it inside.

Only two centimeters after the needle was inserted, blood came out from the needle hole.

At that time, Li Dongshan's pupils just shrunk, and I took a crutches. Good guy, I really have blood luck. Fortunately, I don't have a direct one-third cut. Otherwise, I might have cut all the good tissues.

Wang Linfeng and She Min were immediately overjoyed when they saw this picture. There is still a living organization, that's a good thing. The more muscles that remain, the more muscles can be restored through exercise later, so that the damage caused by this time will be more limited.

Lu Cheng also laughed here and said, "Master, luck is good. There is a blood supply so close to the needle."

"Then I will scrape another centimeter or so." Li Dongshan also nodded.

I just think it’s better to follow the principles as much as possible for the operation. With complete experience, sometimes there will be some small mistakes. In fact, if he cuts a third, he will also find blood supply. At least Li Dongshan thinks so.

Lu Cheng called the syringe needle for a reason. First, he had a deft touch and knew that the blood vessels and muscles there were slightly trembling, and he was not dead.

Secondly, he has glasses that can directly observe the blood vessels. In this way, if someone pokes a place where the blood does not bleed, he sticks directly into the blood vessel, so he can't stop bleeding, right?

Li Dongshan quickly cut open one-third of the muscle that was still fish-colored. Only at the spot of Lu Chengzha, a small amount of blood leaked out. Seeing this picture, Li Dongshan frowned again.

Isn’t it just such a small blood vessel?

Then Li Dongshan took the syringe needle into his hand and pierced it again.

He also needs to make sure again that he can't lose big because of small, if it's only a local blood supply, then he still needs to cut it.

One centimeter!

No blood.

Two centimeters.

Still no blood.

Suddenly, Li Dongshan's face sank again, and he said, "Oh, it seems that there is still no blood supply."

Lu Chengbian said again: "No, I just tried it just now, there should be some, Master, I will try again?"

Lu Cheng had a modest attitude of asking for advice, and a little bit of my attitude that I would correct it if I made a mistake.

So Lu Cheng moved from Li Dongshan's position to another angle on the same plane.

He chuckled, and a tiny amount of blood came out just short of getting in.

It came out again after another tie.

Lu Chengcheng raised his head and looked at Li Dongshan, meaning, there is blood.

His face was blank.

Li Dongshan's face changed at that time.

Although Lu Cheng didn't speak, Li Dongshan really understood. Lu Cheng didn't know what was going on, and he could get into the capillaries every time. That's why the blood came out, and he might still feel the pulse of his blood vessels.

Li Dongshan is involved in trauma, so I know some people, some people are born specifically for trauma surgery, they are extremely sensitive to touch and can feel subtle blood vessel pulses.

Lu Chengcheng is such a person, I have made a lot of money! !

There was a storm in Li Dongshan's heart, but he was expressionless: "Well, it can be retained. As long as there is a little blood supply, the muscles may be retained. Antibiotics can also enter the muscle tissue through the arteries to kill the remaining germs. ."

"Xiao Lu, you feel good today, you continue to look for blood supply, I will be responsible for the debridement."

Lu Cheng said good.

Wang Linfeng and She Min breathed a sigh of relief.

Those who watched Li Dongshan's surgery in the audience also felt that, um, fortunately, fortunately, luck is better.

But Fang Nixin was stupid at the time.

This isn't a good or lucky thing. Haven't you thought about why Li Dongshan didn't get blood, but Lu Cheng got it?

Is this okay?

Then Fang Nixin watched Lu Cheng every time Lu Cheng looked for blood supply, he would be stubborn, and he would still play a joke there, "Master, the blood supply of this muscle is still there."

"This one is too."

Fang Nixin let go of all the hooks she was pulling, and she couldn't rest at all in her heart.

Lu Cheng, you have a problem, and your problem has become a big issue. You hide too deeply.

Fang Nixin was so shocked that she let go of the hook, and She Min immediately took it. He only thought that Fang Nixin was a girl's paper. After all, the girl's stamina was poor. This is all understandable!

If this is known to Fang Nixin, she probably wants to let She Min know how powerful she is in anti-wolves: the level and strength of the black belt in Taekwondo!

There were not too many people on this operation, and many people watched it.

The main sword is Li Dongshan, Lu Cheng becomes the first helper at this moment, and Fang Nixin is the second helper. Then there are Wang Linfeng and She Min as three assists and four assists, but at this moment Fang Nixin's second assist position has been taken over by She Min.

Fang Nixin saw that Lu Chengyi pierced out the bleeding points of the quadriceps from different angles, and then slowly eased her mind, and then vacated the position a little bit and gave up the position. She Min.

Changing the position of the assistant during the operation somewhat affected the process of the operation. Fang Nixin's previous release was originally caused by her lack of consciousness. Changing it again was not suitable.

She went to the position of Sisuke where She Min stood before, and watched Lu Cheng's operation with Li Dongshan, and her thoughts were even more broken.

Fang Nixin was also hit hard this time.

Before, when Li Dongshan took her and Cao Xiaohe, Cao Xiaohe belonged to that kind of soy sauce level, but today it was changed to her. Now Fang Nixin seems to understand how Cao Xiaohe usually feels, and the feeling of being neglected and slapped is really bad.

However, the difference between the height that I usually stand at and the height of Cao Xiaohe seems to be no better than the height difference between Lu Cheng's current height and her current height of Lu Nixin.

Fang Nixin wondered if Lu Cheng had dissected hundreds or thousands of people before he could find the nutrient vessels in his muscles, and he could figure out the shape of them. Otherwise, it would be absolutely impossible to be so precise.

Fang Nixin's doubts are of course a bit exaggerated, but the overall result is even more incomparable. Lu Cheng has top-notch anatomical experience, plus the hands of spiritual touch, he only needs to know the approximate shape of the nutritional blood vessels, and then cooperate with the visualization. Blood flow.

It is more accurate than more anatomical experience.

You should know that the anatomical structure of the human body can only be used as a reference in any operation, and everyone has a certain degree of variability. However, the cooperation of Lu Cheng's three major skills is real-time, and it is more effective than any anatomical experience.

"Master, let's cut a bit more here, I think the outer layer may still be necrotic, so there is no need to keep it." Lu Cheng suggested again.

Li Dongshan's whole body was numb, but according to Lu Cheng's suggestion, he scraped off the necrotic muscle tissue little by little. His technique was exceptionally superb and steady, with absolutely no more or no more than one.

The reason why Li Dongshan was numb was because he was in the process of removing the necrotic muscle without any trace of blood.

What does this mean? It means that Lu Cheng has really touched the pulsation of the blood vessels, so he can judge where there are nutrient blood vessels and where there are none, so that he can accurately make ‘recommendations’.

It's actually a conductor.

Li Dongshan immediately swung his knife and cut off the place Lu Cheng said.

Looking at Li Dongshan's swordsmanship, Lu Cheng was also particularly envious.

Just kidding, this is an operation and not buying melons at the vegetable market. I will tell you to cut a few millimeters. If you cut a few centimeters, you can cut it for me. It doesn't matter if it is too much?

This is a human being lying down. In every sentence he suggested to Li Dongshan, Li Dongshan was stunned. This ability definitely surpassed Lu Cheng's current knife skills.

Debridement and suture is a basic task and the basic task of all open operations.

The most basic thing is to hold the knife firmly, the second step is to cut accurately, and the third is to be able to do whatever you want.

Li Dongshan is now able to do whatever he wants, and Lu Cheng, at best, is already very good.

Although Lu Cheng's current intermediate debridement and suture technique works, it doesn't cause any problems, but compared with Li Dongshan, it still pales in comparison. Still have to practice slowly.

This operation has not even counted the beginning of the operation until now.

In the process of debridement and suture of infected patients, the identification and thorough identification of necrotic muscle is one thing, but thorough debridement is another matter. Bacteria are not muscles, they have a fixed form, they are mobile.

In addition to invading the muscles, he will also be in the periosteum underneath the muscles, in the scar tissue embedded between the periosteum and the steel plate, and even extend along the muscle gap to other places, reaching places that are hard to reach with the naked eye. go.

Thorough debridement means to clean up these things.

However, Li Dongshan did not disappoint Lu Cheng. He suffered a traumatic fracture. He played with steel plates for a lifetime. So when taking out the broken steel plates, he showed Lu Cheng a few tips. After the explanation, he also asked Lu Cheng. I feel very useful.

It seems that Lu Cheng's understanding of internal fixation removal has improved a little.

Li Dongshan said: "For patients with infections after fractures like this, we must clean up the pus moss remaining on the fracture ends, especially the grooves on both sides of the bones, thoroughly excavated."

"There will also be necrotic tissue hidden in it. And we should also pay attention to whether the biceps femoris behind and the muscles on the inner side of the femur are also infected."

"But looking at the color of these muscles, this patient's luck is fairly good. These muscles have not been invaded too much. There is only a thin layer of infection on the surface. We just need to scrape it off. There is no need to remove the muscles. resection."

"The place where there is no necrosis is generally reserved. It is no problem to use sufficient antibiotics after the operation."

This time, Li Dongshan immediately returned to the home court~www.wuxiaspot.com~ He kept taking it with a curette, then put the red and white mixture on the gauze, and then said: "Tour, hard to send again Cultivation is also very important."

Without Wang Linfeng's reminder, the tube was sent down again immediately after the tour, and the barcode was pasted. Another itinerant nurse is also on demand at any time. They are actually the old itinerant who has been with Wang Linfeng many times. This patient has already entered the operating room six times, and they are all very familiar with it.

If Li Dongshan could solve his problem this time, they would also be happy about it, and it would be extremely hard for them to tour for this kind of surgery.

If it is not necessary, they are reluctant to do it the eighth time, but it is estimated that they will do it the seventh time.

Then Li Dongshan began to release private goods again, saying: "When this kind of muscle space is infected, we must not rashly open it too much, otherwise it will only increase the spread of bacteria and eliminate it. They don’t produce much help."

"Once the bacteria enter the airtight cavity, and antibiotics are difficult to reach, delayed infection will occur, that is, after the patient is discharged from the hospital, the infection will occur again, which is also a problem."

"But this problem is not without a solution, wait a moment for us..."
