Fourth Senior Brother had known Zhao Yuan before, even earlier than Mr. Qin.
The lung transplant surgery performed by Jia Xiuzhang in Ruina was the most classic case of organ transplant surgery.
At that time, Fourth Senior Brother paid special attention to Zhao Yuan.
Because this young man's performance is so amazing.
So later, Mr. Qin made an exception at the annual meeting of the Chest Heart and accepted Zhao Yuan as a closed disciple, and he agreed with it very much.
Zhao Yuan's basic skills are very solid, especially the anatomy of the chest and heart, which 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 focus and give the correct treatment method.
Although Zhao Yuan is young, he has already reached the stage where he can cope with all changes by remaining unchanged.
Jia Xiuzhang is currently the person closest to academician level among Jiangmen disciples.
That he was able to find time to support Zhao Yuan fully demonstrates Zhao Yuan's status within Jiangmen.
Fourth Senior Brother took a deep breath and suddenly had an idea of how embarrassing it would be if he was defeated by Zhao Yuan during the surgery.
Fourth Senior Brother's eyes became more determined than ever before, and he wanted to show off all his skills in front of Master and Jia Xiuzhang.
Zhao Yuan did not realize that the fourth senior brother, who looked as gentle as jade, already had a competitive spirit in his heart.
Zhao Yuan and Fourth Senior Brother finished brushing their hands and walked into the operating room together.
The sixteen-year-old boy was lying on the operating bed.
He Jun took a deep breath and said to Zhao Yuan, "Let's get started!"
The originally static scene suddenly moved at the command.
According to the previously discussed surgical plan, everyone performed their duties.
However, at this time, Jiang Jing discovered something abnormal, "her heart stopped beating."
Everyone's hearts suddenly lifted.
Although I knew that the patient's heart was already damaged, I didn't expect that something would go wrong at this critical moment.
He Jun, an experienced man, glanced at the anesthesiologist and said, "Immediately increase the amount of oxygen and adrenaline..."
The injection of epinephrine helps stimulate the patient's physical potential and helps the patient's cardiac resuscitation.
But the patient in front of me was not normal.
His heart is like a rusty spring.
Although adrenaline can provide pressure, the spring may not bounce back smoothly.
Didi didi.
The short siren sound is particularly harsh.
Everyone in the viewing area outside was chatting and laughing at first, but now they were holding their breath.
They know the cruelty of heart disease better than anyone.
It may be fine one second, but it may be in an abyss the next second.
At this moment, half of the boy's feet have stepped into the gate of hell.
The heart has arrived.
The boy died of illness before the operation started!
It is a pity and even a shame for doctors if this news spreads.
To put it bluntly, it is the same nature as the old lady who failed to successfully install the bracket to the designated position.
Of course Zhao Yuan would not allow such things to happen in front of him.
"Be patient and don't be impatient. Don't adjust the dosage blindly. Wait until I establish extracorporeal circulation."
"In ten more minutes, the heart will stop and the patient will go into shock due to blood loss."
"Give me five minutes!"
Zhao Yuan said firmly.
He speeded up the establishment of extracorporeal circulation.
After the extracorporeal circulation is established, the patient can be separated from the failing heart.
Therefore it will have no effect whether the heart stops beating or not.
According to the plan, although Zhao Yuan is the first assistant, he will be responsible for more than 70% of the part, especially the early stage surgery.
Zhao Yuan skillfully performed extracorporeal circulation.
The blood is injected into a blood pump through a hose. After being circulated by the blood pump, it is reinjected into the patient's body.
To put it more vividly, it is just like the flow of Qi in fantasy novels.
When the true energy flows, there are the big Zhoutian and the small Zhoutian.
The great cycle of human blood is when blood starts from the heart, transforms throughout the body, and then returns to the heart. One cycle is a great cycle.
The small circulation is the flow from the lungs to the heart, also called cardiopulmonary circulation.
The principle of extracorporeal circulation uses an artificial heart-lung machine to simulate circulation between the heart and lungs, replacing the functions of the heart and lungs.
It is then used to transport blood into the body to form a large circulation.
It's easy to say, but 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 usage rate of this equipment is not high. Taking Tianhua as an example, last year there were only 80 cases of critical patients using this equipment.
This number is already on the upper side in hospitals across the country. After all, most people who use this equipment have basically already stepped into the gate of hell.
Patients whose financial conditions do not allow it will give up using ecmo.
Secondly, domestic manufacturers mainly produce ordinary membrane lungs, which have a short use time. Long-lasting lungs produced abroad are coated with polymer materials and can last for a longer period of time. Domestic research and development of centrifugal pumps also mostly stays at the prototype stage.
, domestic centrifugal pumps produce products that have not yet been registered.
The technical research and development of centrifugal pumps is not a big problem, but membrane lungs and centrifugal pumps both belong to Class III medical devices, which are the most strictly controlled medical devices and require a large number of clinical trials before they can be approved for marketing.
Because there are fewer cases, clinical trials will last longer, resulting in delayed registration.
In another world, ecmo has received widespread attention mainly due to the outbreak of an epidemic. With the support of the state, domestic manufacturers have increased research and development and investment, and completed a historic breakthrough in a short period of time.
In this world, China's extracorporeal circulation equipment is still at a stuck stage.
"The extracorporeal circulation channel was successfully established!"
Zhao Yuan felt relieved.
He Jun looked at the time, and it was definitely not more than five minutes. He was shocked by this efficiency.
Didn’t I say that my junior brother is an emergency surgeon?
His understanding of extracorporeal circulation is much better than that of ordinary cardiothoracic doctors.
As for the doctor who helped Zhao Yuan, he was also very young. Although there were not many difficult operations, it can be seen from the details that the level of the second assistant was equally good.
He Jun is a person who thinks about problems in a complicated way.
Only by considering all contingencies can we ensure that we can deal with any risks.
The unexpected change in today's surgery is how Zhao Yuan should deal with it if something goes wrong.
At this moment, he had realized that there was nothing wrong with Zhao Yuan.
On the contrary, he can put more pressure on Zhao Yuan.
The exchange of ions, changes in pressure, filtration and concentration of blood, detection of perfusion systems, and the invention of extracorporeal circulation machines have directly improved the quality of thoracic and cardiac surgery.
Just like repairing a car, you cannot repair the engine directly when the engine is running.
To repair the engine, the engine must be stopped or even disassembled.
The car's engine was removed, but it just wouldn't start.
But if a person's heart is removed, he will die.
But with this device, the built-in engine can be temporarily detached and the car can run without delaying the doctor's repair of the heart.
There are two key points in heart transplant surgery, one is heart removal and the other is cardiac blood vessel suturing.
The location, angle, and length of cutting off blood vessels all have very high requirements.
Zhao Yuan began to perform heart removal surgery. The heart at the entrance was like a worn-out rubber ball, just one step away from complete deflation.
He Junze and his assistants trimmed the heart and blood vessels.
Finally ready, He Jun paused for a few seconds, "Will you do the blood vessel suturing?"
Zhao Yuan nodded slightly, "Okay!"
Short and powerful answers with full confidence.
He Jun was wearing a mask, so others couldn't see the smile on his lips.
"Then I'll leave it to you."
Zhao Yuan carefully began to sew.
What he sutured was not only blood vessels, but also the youth and desire for life of a sixteen-year-old boy!
