Doctor: start with the heart

Chapter 80 Fine Surgical Reproduction
06:30 in the afternoon.

Seventh operating room.

At this moment, the girl Xiaoya is lying on the operating table, ready to undergo partial necrotic tissue resection in her right hand.

Zhao Xu presided over the operation, Sun Chang was the first assistant to cooperate with the operation, Su Xiao participated in the operation as the second assistant, and Zhou Xiaoling watched the operation from the sidelines.

At any rate, he has joined the emergency department. Since the last time he talked with the director, the director has also made it clear to Zhao Xu that he will take Su Xiao and Zhou Xiaoling with him in the future. It is a member of the emergency department, and the department has the obligation to train them well.

Anesthesiologist Li Song, who was standing next to the life monitor, looked at Zhao Xu, who was surrounded by three female doctors like stars, with some envy. How could this person be so different?

This Zhao Xu is now a well-known First Affiliated Hospital, so it doesn't matter if his technology has improved quickly, he is still so handsome, and he has such a good relationship with the opposite sex, which makes people a little envious and jealous.

"Doctor Li?!"

When Li Song was in a daze, the equipment nurse Xu Yun standing beside him reminded him softly.

"Ah."

Hearing Xu Yun's reminder, Li Song came back to his senses.

Looking at the life monitor, Li Song nodded. There is no problem with blood pressure and heart rate, and the anesthesia is normal, so the operation can be started. However, looking at the swollen, purple and black right hand of the patient lying on the operating table, Li Song couldn't help but sigh, This is another tricky and difficult operation!
"Doctor Zhao, the patient's vital signs are normal and the operation can begin."

Li Song looked at Zhao Xu and said, envy is nothing but envy, but Li Song still admires Zhao Xu, a person who is based on his own level and has real materials.

"Ah."

Zhao Xu nodded.

"For this operation, it is necessary to remove the necrotic tissue in the patient's right hand, and to preserve the normal tissue in the patient's right hand to the maximum extent, without damaging the function of normal tissue."

Zhao Xu's words were naturally addressed to his second assistants, Su Xiao and Zhou Xiaoling, who were standing beside him.

Although Su Xiao returned home after graduating with a Ph.D., education is one thing, but clinical experience is another.

Graduating with a doctorate can only show that you have passed the test in terms of knowledge, but clinical practice and operation require long-term familiarization and accumulation.

Especially with Zhao Xu's current level of surgery, even a highly talented surgeon would have to accumulate for decades before he could hope to achieve it.

As for Zhou Xiaoling, who has just finished four years of college and is in the middle of an internship, she is a new student with a blank sheet of paper, which is almost blank for clinical practice and needs more teaching.

"Well, I see, senior."

Zhou Xiaoling looked at Zhao Xu with admiration and said.

Su Xiao also looked at Zhao Xu with admiration. Although she is a doctor, it only represents knowledge. Medicine is a discipline with strong practicality. It is not enough to understand it. The most important thing is practical operation. .

Therefore, Zhao Xu, whose surgery level has far exceeded the current resident title, naturally got Su Xiao's attention.

"let's start."

Zhao Xu adjusted, entered a state of absolute concentration, and said seriously.

Following Zhao Xu's order, the operation began.

First of all, it is necessary to cut the right hand, separate the necrotic tissue little by little, and then separate the normal tissue and the necrotic tissue. In this process, the most difficult thing is to remove the necrotic tissue attached to the nerves and blood vessels little by little.

The survival of nerves and blood vessels has a crucial impact on the success rate of transplanting stem cells to grow tissues.

As for the right hand, because it is responsible for the fine operation of the human body, the human body is rich in tiny blood vessels and peripheral nerves.

In short, it's a very delicate operation.

"Scalpel No. [-]."

Zhao Xu looked at the sterilized right hand in front of him, and said to Xu Yun, the equipment nurse standing opposite him.

"Ok."

Xu Yun answered quickly, picked up a scalpel, and handed it to Zhao Xu.

Zhao Xu took the scalpel and gently scratched the back of his right hand, following the cut skin, purple-black blood that had already smelled a little flowed out along the cut.

The people present could faintly smell a bit of rancid smell as the blackened blood flowed out.

no? !
Seeing the swollen black and purple right hand in front of her eyes, Zhou Xiaoling could not help but sigh in her heart when she smelled the rancid smell of blood flowing out.

It's already necrotic like this, can you keep this right hand?
Thinking of this, Zhou Xiaoling couldn't help but look at Zhao Xu.

And Su Xiao was also shocked by the scene in front of her. She knew that the patient's right hand had necrotizing fasciitis, but it was the first time she saw such a rotten and terrifying appearance after the skin was cut.

"What we are doing now is just the removal of necrotic tissue. As for whether the patient's right hand can be kept, it will depend on a week later."

As if aware of Zhou Xiaoling's and Su Xiao's doubts, Zhao Xu explained slowly while operating.

"One week?"

Su Xiao asked with some doubts.

Hearing what Zhao Xu said, she was even more confused.

The right hand has become necrotic like this, even if it is only to remove the necrotic tissue, it can take a week, but what about after a week?

As far as the current situation is concerned, she really can't think of any way to keep this right hand after a week.

"Concentrate on the operation, and you will know when the time comes."

Zhao Xu didn't say anything more. He didn't even mention the specific details of stem cell cultivation technology.

In his opinion, there are still many things to prepare for the large-scale launch of this technology, and this time it is only a preview.

"Ah."

Su Xiao nodded, but she became more curious in her heart.

Next, Sun Chang and Su Xiao, in cooperation with Zhao Xu, gradually removed the necrotic tissue from the blood vessels and nerves.

When the necrotic tissue was almost removed, everyone present couldn't help but gasped when they saw the right hand with almost only the skeleton and a little muscle tissue left, as well as the main nerve and blood vessels.

This is almost the removal of most of the tissue in the right hand. If it relies on natural recovery and growth, it is impossible to grow well.

The only possible way is to transplant.

However, in the current medical field, most of the transplants for the right hand are based on skin transplantation after burns. As for the large-scale transplantation of muscles and fascia, there is no such precedent in clinical practice.

"Cover the fish skin."

Seeing that the removal of necrotic tissue had been completed, Zhao Xu said again.

The necrotic tissue has been removed, and the nerves and blood vessels, as well as the remaining parts of the tissue, are naturally impossible to expose.

At this time, it is necessary to cover the tilapia skin that is close to the human body. On the one hand, it can protect and isolate the outside world. On the other hand, it can also provide collagen and play a role in sterilization.

"Ah."

Sun Chang nodded, and together with Su Xiao, covered the tilapia skin prepared in advance on the right hand that had been peeled off and almost only the skeleton remained.

This operation was naturally not difficult for Sun Chang and Su Xiao, and it was completed quickly.

At this point, the preliminary surgery is over.
