The fourth senior brother knew about Zhao Yuan, even earlier than Qin Lao.

The lung transplant that Jia Xiuzhang performed in Rena can be called the most classic case of organ transplantation.

At that time, the fourth senior brother paid special attention to Zhao Yuan.

Because this young man's performance is really amazing.

So later, Qin Lao made an exception to accept Zhao Yuan as a closed disciple at the annual meeting of the heart, and he agreed very much.

Zhao Yuan's basic skills are very solid, especially the dissection of the chest and heart has reached a very high level.

When a person is particularly familiar with something, no matter how the disease changes, he can quickly find the lesion and give the correct treatment.

Although Zhao Yuan is young, he has reached the realm of adapting to all changes with the same.

Jia Xiuzhang is currently the closest to the level of an academician among the Jiangmen disciples.

He was able to squeeze out time to give Zhao Yuan a platform, which fully explained Zhao Yuan's status within Jiangmen.

The fourth senior brother took a deep breath, and suddenly had an idea, how embarrassing it would be if he was compared to Zhao Yuan during the operation.

The fourth senior brother's eyes became more determined than ever, and he wanted to show all his skills in front of the master and Jia Xiuzhang.

Zhao Yuan didn't realize that the fourth senior brother, who looked as gentle as jade, already had a competitive spirit in his heart.

Zhao Yuan and the fourth senior brother finished brushing their hands and walked into the operating room together.

A sixteen-year-old boy lies on an operating table.

He Jun took a deep breath and said to Zhao Yuan, "Let's start!" ”

The originally static picture moved instantly at the sound of an order.

According to the previously agreed surgical plan, everyone has their own role.

However, at this time, Jiang Jing found an abnormality, "The heart stopped." ”

Everyone's hearts instantly lifted.

Although he knew that the patient's heart had long been broken, he did not expect that something would go wrong at this critical moment.

He Jun glanced at the anesthesiologist with rich experience, "Immediately increase the oxygen infusion, and the adrenaline ......"

The injection of epinephrine helps to stimulate the patient's physical potential and helps in the patient's cardiac resuscitation.

But the patient in front of him is not normal.

His heart was like a rusty spring.

Although adrenaline can give pressure, the spring does not necessarily bounce smoothly.

Drip drip, drip.

The short siren sound was particularly harsh.

The people in the observation area outside were talking and laughing at first, but now they held their breath.

They know better than anyone the cruelty of heart disease.

One second it may be fine, the next second it will step into the abyss.

At this moment, the young man has already stepped into the ghost gate with half a foot.

The source of the heart has arrived.

The teenager died before the operation began!

This is a pity and a shame for the doctor.

To put it bluntly, it is the same as the old lady who did not successfully install the bracket to the designated position.

Of course, Zhao Yuan would not allow this kind of thing to happen in front of him.

"Don't be irritable, don't blindly adjust the dosage. Wait for me to establish cardiopulmonary bypass. ”

"In another 10 minutes, the heart stops beating, and the patient will go into shock due to blood loss."

"Give me five minutes!"

Zhao Yuan said in a firm tone.

He sped up the pace of building cardiopulmonary bypass.

Once cardiopulmonary bypass is established, the patient can be weaned out of the failing heart.

Therefore, it will not make any difference whether the heart stops beating or not.

According to the plan, although Zhao Yuan is a helper, he bears more than 70% of the part, especially the pre-operation part, which is all responsible for him.

Zhao Yuan skillfully does a good job of cardiopulmonary bypass.

Blood is injected through a flexible tube into a blood pump, which circulates and then re-infuses into the patient's body.

To put it vividly, it is the same as the flow of true qi in fantasy.

When the true qi flows, there are big and small weeks.

The Great Week of Human Blood is the transformation of blood from the heart to the whole body to the heart, and a cycle is a Great Week.

The small week is the flow from the lungs to the heart, also known as the cardiopulmonary circulation.

In the principle of cardiopulmonary bypass, an artificial heart-lung machine is used to simulate the circulation between the heart and lungs, replacing the functions of the heart and lungs.

Reuse blood is pumped into the body to form a large circulation.

To put it simply, China can now build a space station, but the entire set of equipment still needs to be imported.

Of course, there are many constraints.

First, the use rate of this device is not high, taking Tianhua as an example, there were only 80 cases of critical patients using this device last year.

This number is already at the upper level of hospitals in the country. After all, most of the people who get on this device have basically stepped into the ghost gate with half a foot.

Patients who are financially unable to do so will give up ECMO.

Second, domestic manufacturers mainly produce ordinary membrane lungs, which have a short use time, and long-lasting lungs produced abroad are coated with polymer polymer materials, which can last for a long time. The research and development of centrifugal pumps in China is mostly in the prototype stage, and the production of domestic centrifugal pumps has not yet been registered.

The technical research and development of centrifugal pumps is not too much of a problem, but membrane lungs and centrifugal pumps are both Class III medical devices, which are the most strictly controlled medical devices, and they need to go through a large number of clinical trials before they can be approved for marketing.

Due to the low number of cases, clinical trials can last longer, resulting in delays in registration.

In another world, it was mainly because of an outbreak that led to a wide range of attention on ECMO. With the support of the state, domestic manufacturers have increased R&D and investment, and have completed a historic breakthrough in a short period of time.

In this world, Huaguo's extracorporeal bypass equipment is still in the stage of being stuck.

"The extracorporeal bypass channel has been successfully established!"

Zhao Yuan was relieved.

He Jun looked at the time, it was definitely no more than five minutes, and he was shocked by this efficiency.

Didn't you say that the little brother was an emergency surgeon?

The understanding of cardiopulmonary bypass is much stronger than that of ordinary chest doctors.

As for the doctor who helped Zhao Yuan, he was also very young, although there were not too many difficult operations, but from the details, it could be seen that the level of the second assistant was also good.

He Jun is a person who thinks about complex problems.

Only by thinking about all the changes can you ensure that you can deal with any risks.

The change in today's operation is how to deal with Zhao Yuan if there is a problem.

At this moment, he had realized that there was nothing wrong with Zhao Yuan.

Instead, he can hand over more of the pressure to Zhao Yuan.

The exchange of ions, the change of pressure, the filtration and concentration of blood, the detection of perfusion system, and the invention of extracorporeal bypass machines have directly improved the quality of thoracic heart surgery.

Just like repairing a car, you can't repair the engine directly when the engine is running.

To repair the engine, it is necessary to make the engine stand still, or even disassemble it.

The car had its engine dismantled and just wouldn't start.

But if a person's heart is torn apart, he must die.

But with this equipment, the built-in engine can be temporarily detached, and the car can run like a car, but it will not delay the doctor to repair the heart.

Heart transplantation has two priorities, one is heart removal and the other is heart vascular suture.

The position, angle, and length of the cut blood vessels are highly demanding.

Zhao Yuan began to have a heart removal operation, and the heart in the eye was like a worn-out ball, and it was only one line away from being completely deflated.

He Jun took his assistant to trim the blood vessels of the heart.

Finally ready, He Jun paused for a few seconds, "Blood vessel suture, will you do it?" ”

Zhao Yuan bowed slightly, "Okay!" ”

Short and powerful answers, full of confidence.

He Jun was wearing a mask, so no one could see a smile on the corner of his mouth.

"I'll leave it to you."

Zhao Yuan cautiously began to stitch up.

He stitched not only the blood vessels, but also the youth of a sixteen-year-old boy and the desire for life!
