"Okay! Brother Zhou Cheng." Zhou Cheng came to the side, so decisive and straightforward, which gave Du Yanjun a backbone!

There was even a feeling of tears filling his eyes. He, who just now was running around like an ant without a leader, quickly gathered his thoughts——

He immediately used a suction device to suck out the blood clots on the surface one by one, and then used a thyroid retractor to slowly move toward the inner layer.

During on-site first aid, although most of the debris or foreign objects will be removed, it is impossible to remove them completely. You must carefully explore during the operation to ensure that there is no residue.

While Du Yanjun was looking for the foreign object, Zhou Cheng had already begun to quickly judge the anatomy.

The arteries at the knee joint mostly focus on the popliteal fossa.

Fortunately, the patient's open joint is in the front. Therefore, the popliteal fossa may be protected and not involved, but the blood vessels under the popliteal fossa, that is, under the tibial plateau, need to be carefully explored.

Moreover, it is necessary to straighten out the shape of the muscles at the origin and insertion points of the tibial plateau, identify the tendons and muscles one by one, and then reconstruct the bone defects and muscle insertion points...

The treatment of simple bone defects is very simple, and Zhou Cheng can also do a simple reconstruction of tendon insertion points.

But when both exist at the same time, the difficulty is not as simple as one plus one, or even a simple exponential increase!

Instead, it directly raises the difficulty level to several or even hundreds of times!

Do we need to reconstruct bones, do we need to reconstruct tendons, and how?

Can muscles grow without rebuilding bones? What if muscles atrophy without rebuilding tendons?

What should I do if my tendon is reconstructed but the reconstructed bone is strained?

The reason why surgery is complicated, or the reason why some diseases are complicated, is because there is no very logical one-to-one correspondence.

We can't even find a perfect corresponding means that is perfect and consistent.

However, this issue should be considered later.

While Du Yanjun was picking out stones, broken gravel, glass pieces and blood clots, he secretly looked at Zhou Cheng and discovered that Zhou Cheng had exposed the corresponding blood vessels and nerves without knowing when.

Come out!

The nerves were held aside by Zhou Cheng with cut rubber gloves, and the blood vessels were fixed with silk threads.

Moreover, Zhou Cheng's fixation is not the kind of fixation that is tied off, but a living knot.

The dead knot was above the blood vessel, which did not tie off the blood vessel, but could pull the blood vessel out. At the same time, he also classified the broken muscles and clamped the tendons with vascular clamps.

Vascular clamps cannot clamp muscles, because this will dissolve the muscle tissue, leading to death similar to rhabdomyolysis. But tendons can be clamped. There are no blood vessels in the tendons, so the clamps will not dissolve!

However, after Zhou Cheng finished doing this, the tours of the Seventeenth and Nineteenth Rooms came to urge him.

Said: "The anesthesia in Room 17 has been done, and Dr. Zhang over there has done the disinfection. I want to ask Dr. Zhou, do you want to go there?"

"I'll be right over!" Seeing this, Zhou Cheng immediately got off the stage!

Untie your gloves and clothes at the same time!

"Brother Zhou Cheng, what is this?" Du Yanjun panicked when he heard that Zhou Cheng was about to step down.

If this operation was completely left to him, he wouldn't be able to handle it.

Now it is no longer a matter of chance, but the situation encountered is beyond the scope of ability, and Du Yanjun cannot handle it.

Although he really didn't want to admit that he was much worse than Zhou Cheng, in fact, he had already recognized the fact that Zhou Cheng was the junior superior in the group. When Zhou Cheng was here, he felt very at ease, as long as he did good things

.

Everything can be left to Zhou Cheng. Before Zhou Cheng came on stage, he panicked a lot!

Now that Zhou Cheng is leaving, he is still panicking.

When there are many opportunities, being unable to seize them is a feeling of powerlessness!

"Debridement first, don't worry!" Zhou Cheng calmly comforted Du Yanjun.

Zhou Cheng must step down.

Seventeen is his main battlefield, this is one of the reasons!

The second thing is that he has already investigated this patient clearly, and can let Du Yanjun slowly remove the foreign body, and then clean up the necrotic tissue. At least this way, the patient's life will not be in danger!

But he hasn't seen what's going on over there next door, so he still has to take a look first to know what's going on!

If this kind of III-degree open knee injury is a minor debridement, then the situation next door will definitely not be much worse. If Zhang Zhengquan is left to bear it alone, if something goes wrong, it will be troublesome.

.

Still not enough manpower.

Teacher Luo.

"Yan Jun, don't throw away these broken bones. Put them in a curved plate later and soak them in complex iodine. I'll go over and take a look at the situation," Zhou Cheng ordered.

It was a helpless thing for Luo Yun to go to the outpatient clinic, but after the person left, the patient still had to be handled by someone, and there was no way to run away!

He only hoped that the twenty-one rooms on Cai Dongfan's side could be completed as soon as possible, and then an operating room could be replaced in the gap.

Otherwise, Zhou Cheng would really feel a little unfocused when running on both sides.

You have to be dedicated when doing surgery.

"Okay, Brother Zhou Cheng." Du Yanjun was a little panicked when he saw Zhou Cheng leaving. He was also a little afraid that the patient would suddenly disappear after Zhou Cheng left.

However, after Zhou Cheng had sorted out the muscles, blood vessels and nerves, the operation was actually not that difficult, and he could start walking step by step.

Zhou Cheng went out, washed his hands directly, and then entered Room 17.

While putting on his clothes, he asked directly: "Quanzi, what is the condition of this patient?"

"Arterial embolism, plantar damage, and amputation of the middle and lower legs!" Zhang Zhengquan hurriedly replied. He also understood the patient's condition clearly in advance!

Zhang Zhengquan knows.

Luo Yun suddenly left, and Du Yanjun next door couldn't handle it alone. Zhou Cheng was helping next door before, and he wasn't in the hospital yesterday. He didn't do ward rounds in the morning. He definitely didn't have time to understand so many things.

"How long has it been tied?" Zhou Cheng asked again.

"Did you apply a tourniquet?"

Zhou Cheng looked at the patient's foot. Except for the very bloody and damaged sole, it should be a girl's foot, and she should not be very old.

Then he walked to the operating table and looked around quickly, his mind racing around.

If the embolism lasts not long, the amputation can still be saved!

Amputation is the last step in orthopedics. He does not want patients to go to this step unless it is an emergency.

"The tourniquet was applied." Zhang Zhengquan hurriedly replied.

"I don't know how long it has been tied up."

"Little sister, do you know when you were admitted to the hospital?"

"Boom!~"

"Bah!~" Lying on the operating table was a young girl, who was under spinal anesthesia at the moment. She was sniffing and sobbing.

"Boom!~"

"Bah!~"

The sound of air hitting the nasal cavity and piercing the nasal mucus sounded one after another, and so on.

"Little girl?" Zhang Zhengquan asked again.

"I was admitted to the hospital at around four o'clock, doctor!"

"Bah!"

"Woo! Uh-huh.~~~" As she spoke, her body began to tremble slightly.

Both lower limbs were anesthetized, but the abdomen was still shaking slightly!

Heart of beauty in everyone!

Let alone a little girl, she has always been looking forward to growing up and wearing nice clothes and high heels...

Amputation was something she had never considered, but when she arrived at the hospital, the doctor told her that amputation was needed to save her life, and there was nothing she could do.

Her parents had argued with the doctor many times, but to no avail.

I even mentioned transferring to Shonan University Affiliated Hospital and Second Hospital, but to no avail.

There are no beds.

Now, the doctor asked again, and she could only reply like this.

Zhou Cheng looked at the time on the timing panel and saw that it had already reached 8:41. If calculated based on the time of the embolism, the embolism should have only lasted for more than four hours.

Zhou Cheng looked at the wound again, and there was looming active bleeding. Although it was not much, it also confirmed that the little girl's embolism might not be that serious.

This is not necessarily an indication for amputation?!

"Is amputation necessary?" Zhou Cheng did not dare to speak nonsense and stepped forward to lower his voice with Zhang Zhengquan.

However, when Zhou Cheng asked this question, Zhang Zhengquan thought of what Zhou Cheng wanted to do and hurriedly left the operating table for a distance, feeling that the distance was almost enough.

She approached Zhou Cheng and said in a low voice: "Brother Zhou Cheng, she jumped in line for this amputation surgery! This is also considering that she is relatively young."

"There are several emergency rooms ahead! If we need to perform limb salvage surgery, it won't be too late, right?"
