That's right!

Even though Zhou Zhou was already familiar with this kind of full valve replacement surgery, he still had to be cautious.

But every patient's situation is different.

There were also a few pairs of eyes staring at him.

All four valves are to be replaced.

That's going to have to come one by one.

But before that, there's a big project to do.

Establishment of cardiopulmonary bypass. Give your heart a break.

Cardiopulmonary bypass can be said to be a necessary condition for major heart surgery.

In the era when there was no cardiopulmonary bypass, heart surgery was known as a forbidden area for surgery.

After the invention of cardiopulmonary bypass, bloodless cardiac surgery was performed.

Now all Monday has to do is make the exclusion zone safe.

Silent in the operating room.

Zhou Zhou's deep voice rang out: "No. 11 sharp blade." ”

The instrument nurse immediately handed over a scalpel with a sharp head.

Modern surgeries have strict requirements, and each instrument has its own use.

The No. 11 sharp blade is held in the hand, and the slender and thickened stainless steel handle fits perfectly in the palm of Zhou Shengsheng's hand.

Through the latex gloves, Zhou Zhou also feels that the hand feels excellent.

Director Tian and Cao Xiangwen have also done a lot of large-scale heart surgeries.

When I saw this scalpel, I knew that on Monday I was going to cut the aorta and prepare for the aortic cannulation.

If the previous circumcarcity is precise, a young extracardiac director can do the job.

The construction of cardiopulmonary bypass here is already a difficult operation.

Basic vascular incision and suturing requires considerable experience.

Only veterans who have been through a hundred battles can be handy.

Cao Xiangwen looked more carefully.

He wanted to see from every action of Zhou Yi that Zhou Yi was outside his heart.

With the scalpel in hand, Zhou Zhou felt very steady.

He straightened the scalpel upright.

Now he's going to make a gap in this aorta.

Technique is very important at this time.

The No. 11 scalpel, with its sharp edge, is perfect for the job.

Monday slowly walked the knife on the aorta.

The whole process is like carving.

If you want to say what surgery is the most exquisite, when pushing vascular surgery.

The notch opens and the prepared aortic cannula is inserted.

This intubation is also exquisite, too thin and too thick.

Aortic cannulation that is too thin can increase perfusion resistance and even lead to tissue hypoperfusion, while too thick aortic cannulation can affect blood flow during cardiac contraction because the cannula occupies too much space in the aorta.

Every bit is down to the eye.

However, there is no difficulty for Zhou Sheng, who is already very rich in heart surgery.

The tube is inserted into the aorta and fixed with a large skin needle and a 10-gauge silk thread.

The entire aortic cannulation is considered complete.

This is just the first step in the establishment of cardiopulmonary bypass.

Next, there is the cannulation of the superior vena cava, the inferior vena cava, the insertion of a left heart drain, and finally the insertion of a coronary perfusion needle.

At this point, the entire cardiopulmonary bypass has been built.

"Aortic occlusion forceps!"

Monday gave an order, and the instrument nurse next to him handed over a pair of slender pliers.

As the name suggests, it blocks the aorta.

Monday took it and carefully clamped it over the ascending aorta to block the aorta. The blood is blocked and can only pass through the extracorporeal bypass device.

At this time, the heart is perfused with asystole fluid, and the heart stops beating temporarily.

Stopping the heart is another powerful tool in extracardiac surgery, just like cardiopulmonary bypass.

The purpose of cardiopulmonary bypass is to keep the heart in a bloodless state.

But when the heart is bloodless, it still beats.

This vitality is of course a symbol of life for the body, but for the surgeon, it is a kind of torment.

Cardiac surgery is a high-precision operation, and a heart that is always "moving" is obviously not a good surgical environment.

At this time, the heart stops beating, and it plays a magical role.

Cardiac arrest fluid is a high-potassium solution, which is a peculiar solution that, when perfused into the heart, contains potassium ions that have an inhibitory effect on the heart muscle.

The heart will quickly enter a state of relaxation and stop beating.

When it is time to get the heart back to beating, the operation is also very simple, as long as the aortic blocking forceps are released, the blood flushes out the high potassium solution in the heart, and the heart will return to beating normally.

The bloodless, stationary surgical environment is now complete.

The patient's heart slowly relaxes.

Since birth, after nearly 70 years of non-stop beating heart, this moment has finally quieted down under human intervention.

It is often said that when the heart stops beating, it is the end of life.

But this time, under such a surgeon as Monday.

This sentence should be rewritten.

At this moment, the heart stops beating, which is not the end of life, on the contrary, it represents the beginning of another life.

Of course, the beginning of this new life requires the skill of a surgeon like Zhou Zhou.

There was silence in the operating room.

The red blood swirls through several clear catheters and flows into an oxygenator, a centrifugal pump, and a thermostat tank......

This is proof of life continuity.

Look at everything in front of you.

Director Tian was full of emotion in his heart at this moment.

Although I have had many heart surgeries.

But every time he saw this kind of scene, he had a strong sense of ritual.

The heart stops beating.

Only the equipment is running.

The sanctity of life made Director Tian feel pressure and responsibility.

Although he was not the main surgeon of this operation, he couldn't help but say at this time: "Xiao Zhou, be careful." ”

Zhou Sheng knew that Director Tian's reminder was completely kind, a reminder from the seniors to the juniors, and a kind of respect for life.

Zhou Sheng nodded and said, "Understood!"

The replacement of the four valves officially began.

First, Monday chose to start with an aortic valve replacement.

"No. 11 Blade!"

The instrument nurse handed it over.
