When a doctor opened a plug-in

"Non-invasive vascular clamp."

"gauze!"

"Stop bleeding!"

...

As the operation progressed, Tao Mi personally beat him, Qian Lin looked at Chen Cang, daring not to say anything, but... he has already been promoted to two by now his biggest enemy.

First of all, the first one is Daddy!

The second is Chen Gou!

It's not that Chen Cang is as important as his father.

It's not that his father is like Chen Cang!

Anyway... this is the goal Qian Lin has worked hard for in this life.

Tao Mi likes to beat Chen Cang very much now, even if the coefficient of the chief sword is given to Chen Cang.

After all... Stealing a teacher must have the consciousness of stealing a teacher.

It’s fine if you don’t pay the tuition, you can’t make money, right?

Since Chen Cang could perform cardiac surgery, Tao Mi has always felt that he is the second beneficiary and has learned a lot of good things.

In the past, Xia Gaofeng was always invited for surgery in the province, and then Tao Mi, but... it has been different recently.

Let's start inviting Director Tao!

It has already been realized that Director Tao has accumulated a lot of accumulation and made a late bloomer!

This makes Director Tao a lot happy.

However, there are not many good days. I think that Chen Cang will go far after the New Year, but Tao is the most reluctant person.

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

Say it's learning, but in fact, it's about inspiration.

Getting what you need from other people's operations is what Director Tao needs.

When the atrium was incised and entered the right atrium, Chen Cang took a scalpel to cut the fossa ovale longitudinally, expanding it up and down.

Chen Cang glanced at Qian Lin and said:

"When extending downward, it is best to be biased toward the lumen, when extending upward, avoid inward deviation, because this way, you can avoid accidental injury to the aortic sinus."

This operation was also Chen Cang's perception, and it might be useless to Tao Mi.

But for Qian Lin and Classmate A, it was a rare experience.

Qian Lin suddenly realized that, looking at Chen Cang's eyes softened a bit...

Do you want to let him go?

Qian Lin hesitated!

In fact, Chen Cang is also very good in many cases.

Chen Cang continued: "You have to lose weight. After all, your hands are too fat to affect your performance."

Classmate A held back, but didn't dare to laugh, and let out a fart to show respect!

Qian Lin shook his hands. Where is my knife?!

Tao Mi smiled.

It's normal to joke in the operating room. Chen Cang is okay. Zhang Youfu likes to talk about meaty jokes. At the beginning, he often made the nurse blush.

Mitral valve replacement surgery actually means that the mitral valve becomes stenosis, the valve has been severely contracted, and the subvalvular disease is severe. It cannot be repaired by plastic methods. The valve must be replaced.

There are many valves inside the heart. Between the atria and the ventricles, blood flows through the valves. This is the door of the heart, but the door opens in one direction. When the heart contracts, it opens once. Same as the machine.

Because the blood can only flow in one direction, it cannot be allowed to flow back. The function of the valve is to block it when it flows back.

However, the mitral valve is a one-way door from the left atrium to the left ventricle. When the mitral valve is stenosis or insufficiency, blood flows back into the heart, which causes heart disease.

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

However, the mitral valve is redundant, but it has been severely contracted and cannot be used anymore, even if it is not meaningful.

Chen Cang simply cut it. This process is called flap cutting for short, but it can't be removed too much to avoid damaging the ventricular wall.

When the operation was proceeding slowly like this, Chen Cang was suddenly stunned!

He found a problem!

That is, there are some small thrombi remaining on the wall of the left ventricle.

Suddenly Chen Cang was stunned.

If you don't observe carefully, it is difficult to find this problem!

And this is due to Chen Cang's vision enhancement by 50%, only then discovered this.

How is this going?

Then Chen Cang quickly looked at the original mitral valve.

Suddenly, something happened. If the heart is normal, the blood can flow unimpeded, but when the mitral valve is stenosis, blood cannot flow from the left atrium into the left ventricle at a normal speed!

Moreover, the blood pools and rotates in the enlarged left atrium, and the flow rate slows down, which may form small thrombi.

And these blood clots are all time bombs!

When it comes to the coronary arteries, it is coronary heart disease, and when it comes to the cerebral vessels, it is cerebral infarction!

A long time of mitral valve stenosis can lead to changes in the structure of the heart, such as the enlargement of the left atrium!

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

No wonder the patient will have two consecutive cerebral infarctions in a period of time.

There is a reason for everything.

However, this patient is due to this special condition caused by mitral valve stenosis.

What is the meaning of cough water?

correct!

Chen Cang began to observe along the great blood vessels.

wrong!

Chen Cang suddenly realized one thing, he might have gone astray.

I have been going to associate the infarction with the cough drops.

Chen Cang is always the cause of emboli formation and cough water, while ignoring the direct cause of infarction!

That is atrial fibrillation!

Suddenly!

Chen Cang just realized this, and he found that the task progress in his mind suddenly increased by 5 points!

At this moment, Chen Cang was overjoyed!

Could it be...

Is this cough drops the cause of atrial fibrillation?

Correct!

Probably!

Codeine phosphate itself is a drug that excites the central nervous system, and large amounts of it can cause the adverse reactions of tachycardia.

These are all acceptable.

But if you induce atrial fibrillation, this is not acceptable.

What is atrial fibrillation?

It is the irregular and ineffective contraction of the atrial disorder, which changes the atrial rhythm, and the contraction of the ventricle becomes irregular, and atrial fibrillation drives the ventricle faster.

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

Therefore, in many cases, the patient feels flustered.

However, when atrial fibrillation occurs frequently, complications will appear.

Think of the first patient, pulmonary embolism, and atrial fibrillation!

The second patient was also palpitation, and atrial fibrillation induced multiple cavitary infarctions.

Now the third patient is still infarct!

At first, Chen Cang thought that cough water might induce damage to the vascular endothelium, but now it seems to act directly on the heart.

Thinking of this, Chen Cang suddenly became worried.

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

If this kind of cough drops prevails, what will happen?

Everything seems to become so serious!
