Chapter 749

"Noninvasive vascular forceps."

"Gauze!"

"Stop bleeding!"

……

During the operation, Tao Mi personally attacked Chen Cang. Qian Lin looked at Chen Cang and dared not say anything, but... His biggest enemy has been successfully promoted to two.

First, Dad!

The second is Chen dog!

Not that Chen Cang is as important as his father.

His father is not the same dog as Chen Cang!

Anyway... This is Qian Lin's goal in his life.

Tao Mi now likes to fight for Chen Cang, even if the coefficient of the main knife doesn't matter to Chen Cang.

After all... You have to have some awareness of stealing a teacher.

If you don't pay the tuition, you can't still earn money, can you?

Since Chen Cang became a cardiac surgeon, Tao Mi always felt that he was the second beneficiary and learned a lot of good things.

In the past, Xia Gaofeng was always invited first and then Tao Mi when consulting for surgery in the province, but... It's different recently.

Let's invite director Tao first!

Outside, I have realized that director Tao has accumulated a lot and made great achievements late!

This makes director Tao very happy.

However, there are not many good days. Thinking that Chen Cang will fly away after the new year, in fact, Tao is the most reluctant person.

However, I didn't expect to learn Chen Cang's mitral valve surgery before I left.

It's learning. In fact, preparation is inspiration.

Director Tao needs to get what he needs from other people's surgery.

When the atrium was cut into the right atrium, Chen Cang took the scalpel and cut the oval fossa vertically, expanding up and down.

Chen Cang glanced at Qian Lin and said:

"When extending downward, it's best to deviate to the direction of the inferior cavity. When extending upward, avoid inward deviation, because in this way, you can avoid accidental injury to the aortic sinus."

This operation is also Chen Cang's perception. It may not be useful to Tao MI.

But for Qian Lin and classmate a, it is a rare experience.

Qian Linton suddenly realized when he looked at Chen Cang, and his eyes softened a little

Do you want to let him go?

Qian Lin hesitated!

In fact, Chen Cang is also very good many times.

Chen Cang continued, "you have to lose weight. After all, your hands are too fat to play."

Classmate a held back, but he didn't dare to laugh and farted to show his respect!

Qian Lin shook his hands. Where's my knife?!

Tao Mi smiled.

It's normal to joke in the operating room. Chen Cang is OK. Zhang Youfu likes to talk about meat jokes. At the beginning, he often makes nurses blush, but now little nurses often tell jokes to Zhang Youfu, and director Zhang blushes.

Mitral valve replacement surgery, in fact, is that the mitral valve becomes narrow, the valve has serious contracture, and the subvalvular lesion is heavy. It can not be repaired by plastic method. We must replace the valve.

There are many valves inside the heart. Between the atrium and ventricle, blood flows through the valves. This is the door of the heart one by one, but the door is opened one way. As soon as the heart contracts, it opens once, just like a machine.

Because the blood can only flow in one direction, it can't be allowed to return. The function of the valve is to block the return.

However, the mitral valve is a one-way door from the left atrium to the left ventricle. When the mitral valve is narrow or incompletely closed, the blood in the heart flows back, which causes the disease of the heart.

What Chen Cang needs is to replace this valve with a new artificial door. In this way, it can play the same role.

However, there is still excess mitral valve, but it has severe contracture and can't be used, even if it is of little significance.

Chen Cang's crispness is cut. This process is referred to as valve cutting, but you can't cut too much to avoid damaging the ventricular wall.

When the operation was going on so slowly, Chen Cang was suddenly stunned!

He found a problem!

That is, there are some small thrombus residues on the wall of the left ventricle.

Chen Cang was stunned.

If you don't observe carefully, it's hard to find this problem!

And it was thanks to Chen Cang's vision enhancement of 50%, which was discovered.

What's going on?

Then Chen Cang hurriedly looked at the original mitral valve.

A sudden reaction came. If the blood flow is unobstructed when the heart is normal, but when the mitral valve is narrow, the blood cannot flow from the left atrium to the left ventricle at a normal speed!

Moreover, the blood is silted and rotated in the enlarged left atrium, and the flow rate slows down, which may form small thrombus.

And all these thrombi are time bombs!

To the coronary artery is coronary heart disease, to the cerebrovascular is cerebral infarction!

Mitral stenosis for a long time can lead to changes in cardiac structure, such as the expansion of the left atrium!

The enlargement of left atrium is closely related to atrial fibrillation, which is the most common cause of cardiogenic embolism.

No wonder the patient has cerebral infarction twice in a row over a period of time.

Everything has a reason.

However, this patient was caused by mitral stenosis.

What is the meaning of cough water?

by the way!

Chen cangshun began to observe the large blood vessels.

incorrect!

Chen Cang suddenly realized that he might have deviated.

I've been connecting the infarction with cough water.

The cause of Chen Cang's thrombosis is always related to cough water, while ignoring the direct cause of infarction!

That's atrial fibrillation!

Suddenly!

Chen canggang just reacted to this. He found that the task progress in his mind suddenly increased by 5 points!

At this moment, Chen Cang was overjoyed!

Is it

Is this cough water the cause of inducing atrial fibrillation?

yes!

stand a good chance!

Codeine phosphate itself is a drug that excites the central nervous system. Taking a large amount of codeine phosphate itself can lead to adverse reactions of tachycardia.

These are acceptable.

But if you induce atrial fibrillation, it's not acceptable.

What is atrial fibrillation?

That is, the disordered and irregular invalid contraction of the atrium changes the atrial rhythm, and the ventricular contraction also becomes irregular. Atrial fibrillation drives the ventricular acceleration.

This can induce a series of serious diseases such as cerebral artery embolism, peripheral vascular embolism, pulmonary embolism, sudden cardiac death and so on!

Therefore, many times, patients feel flustered.

However, when atrial fibrillation often occurs, complications will occur.

Think of the first patient, pulmonary embolism, who also had atrial fibrillation!

The second patient, also flustered, atrial fibrillation induced multiple lumen infarction.

Now to the third patient, it is still infarction!

At first, Chen Cang thought that cough water might induce the destruction of vascular endothelium. Now it seems that it acts directly on the heart.

Thinking of this, Chen Cang immediately worried.

How many patients in the country have the original disease of infarction?

If this cough water is popular, what will happen?

Everything seems to be getting so serious!
