Chapter 1202 Six Genggeng Is Back!

After taking the scalpel.

Chen Cang held his breath and lightly touched the blood vessel wall with his hand, wanting to feel the gurgle of arterial blood pressure and the pressure on the blood vessel wall.

Vaguely, Chen Cang could feel it.

But it's too difficult!

It may be said that the entire operation is very difficult.

"Sodium nitroprusside."

"Propranolol!"

...

Before the operation, in order to ensure the patient's condition, Chen Cang could only give the drug again.

Rather than the difficulty of the operation, it is more about the challenges of the patients themselves.

Multiple aortic dissection is not 1+1+1=3, it is as simple as doing three dissection operations.

The tension and elasticity of the blood vessel wall are limited. When the tension bearing capacity of the blood vessel wall fibers reaches a limit, if one of the operations is performed after the blockage, the pressure on other blood vessels will increase a lot!

A little carelessness may lead to intraoperative dissection rupture and aggravate the condition!

Even let the patient die on the operating table.

Here, the blood transfusion department has completed blood matching, and according to Chen Cang's request, prepared blood for one person.

Nearly 5000ml of blood already has 1000ml ready to warm up.

Everyone was nervous, and it was probably the most difficult operation they had ever had.

Looking at the thick and even deformed blood vessel wall section by section, although the bulging dissection is not very obvious, there is an indescribable strangeness.

From the aortic arch, to the thoracic aorta, to the abdominal aorta.

Before the operation started, I encountered the first problem!

That's how to get started! ?

Is the traditional, iliac artery replacement performed first? Then complete the abdominal aorta, so as to ensure the blood flow of the kidneys and not induce liver and kidney function damage?

But!

The most critical ascending aorta and thoracic aorta are the difficulties and the key points.

Now once the iliac artery and abdominal aorta are clipped, the systemic blood flow is limited, and the change in blood flow directly affects the patient's systemic blood pressure!

In case, what Chen Cang said was in case!

In the event of a rupture of the thoracic aorta during the replacement of the abdominal aorta and iliac artery.

Can anyone help me deal with it?

Operation!

Not alone after all!

A qualified and excellent team can make Chen Cang have no worries.

But at this time, when Chen Cang does not have his own excellent team, he needs to consider more clearly and thoroughly!

Even think of any possibility!

to take countermeasures.

After much deliberation, Chen Cang decided to perform ascending aortic replacement first!

Is it that difficult?

It will definitely be bigger, but it won't cause a series of bang bang vascular dissection ruptures, leading to massive bleeding, and then too late to stop the bleeding and repair and lead to death!

Of course, it is also possible to forcefully clip the place where the ascending aorta is cut off.

But……

If the blood supply to the spinal cord and nervous system is insufficient due to hemostasis, it will lead to ischemia and hypoxia necrosis of the nervous system.

Patients may indeed survive.

But what's the difference between living and dying like this?

Watching Chen Cang lightly touch the blood vessel with one hand, while holding the scalpel in the other, his eyes were fixed on the monitor.

Everyone thought that Chen Cang was waiting for the medicine to take effect.

It was impossible to see that Chen Cang was actually anxious in his heart.

However, Hou Liang and Zhang Peiyi were anxious and noisy in their hearts, and they were really uneasy.

They are really clueless!

Don't know how to handle the patient.

Don't even know how to get started.

Hou Liang is much more professional than Zhang Peiyi, but this is the first time Hou Liang has discovered what it means: the more you know, the more afraid you will be!

It was precisely because he understood the difficulty of this operation that he was even more afraid, and even at the beginning of the operation, he lost confidence!

This situation is not unique, he has seen it in many patients with extremely high mortality.

He raised his head and glanced at Chen Cang, but it was the first time he saw such calm eyes.

Facing such a patient, Chen Cang... Isn't he nervous?

Just at this time!

Chen Cang gave a surgical plan!

"Low temperature circulatory arrest, ascending aorta replacement!"

The anesthesiologist is the director of the anesthesiology department. After hearing Chen Cang's words, he nodded and started work.

This is his first collaboration with Chen Cang!

He hoped it would be smoother.

The young and promising director Liang Tai quickly began to deal with it in an orderly manner.

Liang Tai's fellow apprentice and brother is Zhou He, that is, Director Zhou He of the emergency center.

Even though Liang Tai has reached the director level in the Provincial People's Hospital, he still respects Zhou He!

He often heard Senior Brother Zhou He say that Chen Cang was amazing.

He remembered one sentence very clearly!

"Professor Chen's surgery, don't ask why! Just cooperate fully!"

He used to think this sentence was a bit exaggerated.

But when he saw the operation today, he realized that it was not an exaggeration at all.

Because he is very clueless about the operation.

He seems to know how long it took for his senior brother to become like this?

Seeing the cooling down to the nasopharyngeal temperature of 30 ℃!

Chen Cang glanced at Hou Liang, Zhang Peiyi, anesthesiologist Liang Tai, and every nurse!

Although there is only one eye, but the eyes are very sharp!

Chen Cang said in a calm tone: "I will block the ascending aorta next and perform a replacement operation. I don't want to exceed 20 minutes for the entire operation time!"

"In these 20 minutes, I hope everyone will do their best and cooperate with me!"

These plain words stopped in the ears of everyone, like a thunderbolt!

20 minutes?

Complete ascending aorta replacement?

This is crazy too!

And not only is Chen Cang crazy alone, but every one of them needs to accompany Chen Cang crazy!

nervous?

nervous!

Are you stressed?

Have!

But seeing that the chief surgeon, Chen Cang, was so determined, everyone couldn't help being driven by this momentum!

"Are you ready?"

"Ready!" Everyone nodded in unison!

As soon as he finished speaking, Chen Cang took the hemostatic forceps and decisively blocked the ascending aorta 3.0cm away from the origin of the innominate artery!

This distance is very important!

No more, no less, just happened to play a key role in the operation!

Low temperature for 20 minutes!

Circulatory cessation damage is not apparent.

Even many surgeries require hypothermic circulatory arrest for 40 minutes.

Chen Cang squeezed the time to less than 20 minutes, just to ensure the key to the operation, which is also the need for the follow-up operation!

At this time, Chen Cang quickly said to Hou Liang who was beside him: "Cardiac cardioplegia! Ready to inject!"

Hou Liang nodded quickly and began to prepare.

And after Chen Cang finished speaking, without any pause, he directly picked up the scalpel to cut the arterial dissection and passed through the left and right coronary arteries!

Surgery time is limited!

Chen Cang can't waste time on these tasks!

Because the next anastomosis work, is the top priority of the surgery!

At this moment, the director of the imaging department and the director of the blood transfusion department on the side... Everyone stood around, watching this scene and couldn't help but get excited!
