"It's a bit of a hassle!"

Zhang Jiahao and Wang Zhicheng stared at the big screen tightly.

The previous mechanical flap fell off, but it did not fall off completely, and the root and the annular wall of the valve were stuck to each other, which was quite a troublesome situation.

It does not fall off completely, the adhesion is relatively tight, and brute force cannot be used.

This is the heart, not breaking steamed buns, not cutting vegetables, a little force, once it causes heart damage, it will be a big trouble.

At the same time, because the patient's heart is much larger than the ordinary heart, and the flap height of the new memory metal version is 4.5, the incision is also selected at the position of 4.5, which is not easy to locate in such a long position, and it is also difficult to separate the adhesion part.

"It's quite difficult to separate. ”

"yes, you have to be careful. ”

The doctors who watched the operation were all talking.

"But with Dr. Solis's level, the separation should still be able to be separated smoothly, right?"

"Second replacement, there are few domestic hospitals that can do this situation, and there are only a few big hospitals such as Yanjing, Xiehe, and Shanghai, and Dr. Solis must be fine. ”

In the operating room, Solis had a calm face and whispered to Fang Han.

"Electric knife, 20 electrocution and electrocoagulation!"

Fang Han's voice sounded in the operating room.

"Bar 31 line!"

Solis carefully peeled off the old artificial mechanical ring.

"Vascular clamp!"

Fang Han accompanied Solis and gave orders for Solis from time to time.

The entire operating room was quiet at this time, the observation room and the main venue were also temporarily quiet, and all the doctors also stopped discussing for the time being, watching Solis and Fang Han and others operate.

The root of the artificial valve and the wall of the valve ring are very tightly glued, and you must be careful when separating, any pulling will cause damage to the heart, and this separation is also a difficult point in the operation.

"Take it out!"

"It was taken out without a hitch. ”

In about ten minutes, Solis successfully removed the old artificial valve, and both the operating room and the doctors watching the operation let out a long breath.

"The artificial valve has been removed, but the next step is still very difficult to operate. ”

"Yes, the patient's heart is two to three times the size of an ordinary person, which makes the patient's aorta very large, and the placement of the new memory metal valve is also a problem. ”

"yes, it's not easy to place. ”

"The original aortic valve was so torn that there wasn't enough tissue to support the new metal valve. ”

Zhang Jiahao and Wang Zhicheng also analyzed.

As one of the top cardiologists in China, this is the fastest way to make progress by constantly analyzing the difficulty of the operation, empathizing with others, and then watching other people's surgeries.

Just like what Fang Han said to Li Xiaofei and others before, as a rookie doctor, you must not be afraid, when you can participate, you should express your opinions as much as possible, not afraid of mistakes, and don't be afraid of being scolded.

As a rookie doctor, there are few opportunities to get started, and there are people to check it, even if the opinion is wrong and the opinion is incorrect, there will be no serious consequences, at most it will be reprimanded by the attending officer.

But this kind of opportunity is very difficult, even if it is wrong, even if it is scolded, the lesson of this time will be deeply imprinted in my mind.

As a doctor, in the actual treatment and operation, it is necessary to avoid making as few mistakes as possible, but before practice, you can completely substitute yourself into it, consider how to treat yourself as an attending patient, and why you treat it this way......

"Diameter 25 mm, metal flap ready. ”

After measuring, Solis whispered to Fang Han, and Fang Han promptly instructed the instrument nurse on the side.

Wang Zhicheng nodded: "How to put the memory metal petal is indeed a problem. ”

This kind of memory metal valve is usually stored at a low temperature of 0 to minus 4 degrees Celsius, and this memory metal valve compresses in low temperatures, and once the ice water is taken out, it will expand instantaneously.

Of course, this attribute is also the reason why the memory metal valve does not need to be repaired, but at the same time, because of this characteristic of the metal valve, the difficulty of placement has also greatly increased.

Where and how to place it must be very cautious, because the metal flap is inflated, and the difficulty of placing it is quite large.

Outside the operating room, Zhou Chen's parents sat on the row of chairs opposite the operating room, and the two of them glanced at the direction of the operating room from time to time.

For them, who had already waited for an operation, this time their hearts were more worried than the last time.

The difficulty and risk of this operation are very high, and the doctors have made it very clear before the operation.

Even if Solis was the one who performed the surgery, the doctors would explain the risks and consequences of the operation to the patient's family in as much detail as possible, which made Zhou Chen's parents even more worried and afraid.

"Don't worry, Chenchen will be fine. ”

Zhou Chen's father took his mother into his arms and gently patted his mother's back.

Zhou Chen's mother's eyes were red and swollen, and tears couldn't help but slide down.

"Placement failed!"

In the operating room, Solis placed for the first time, failed, and hurriedly removed the metal flap.

"Recompress!"

Fang Han handed the metal flap he had taken out to the doctors and nurses on the side.

If the delay is too long, the metal valve will swell, and it will not be placed, but in such a short time, the doctor will not have much time to consider the position, and the position will be easily deviated, and if the placement fails, it must be taken out immediately for secondary placement.

After removing the metal flap, it is necessary to put cold water again to compress it and make a second attempt.

"Failed, failed the first placement. ”

In the observation room and the main venue, all the doctors were also staring closely at the surgical scene.

With the failure of the first placement, the doctors' hearts also tugged.

"It's been 40 minutes since cardiopulmonary bypass was established, right?" a doctor asked.

"Well, it's been almost forty minutes. ”

"It's been a third of the time, and if the successive placements fail, it's a problem. ”

"But this is also something that can't be helped, in addition to the experience of seeing a doctor, it also depends on luck. ”

"Yes, the patient's heart is too large, the aortic valve is too large, it is difficult to locate, it is difficult to place, it is indeed difficult. ”

If it is placed too high, it will affect the normal coronary artery opening, resulting in very severe acute heart failure, the patient may not be able to get off the operating table, if the position is too low, it is easy to damage the structure in the ventricle, and conduction block will occur.

"Failed again!"

The second placement failed again, and the metal flap was recompressed again.

"Failed twice in a row, time is running out!"

Zhang Jiahao whispered to Wang Zhicheng.

In principle, the time of cardiopulmonary bypass should not exceed two hours, but two hours is already the limit, and the placement of the metal valve does not mean that the operation is over, and the time for the follow-up part is very tight, and if there is any accident again, then it is very likely that it will overtime.

"Dr. Solis, I'd better come. ”

Fang Han whispered to Solis, speaking in English.

Solis nodded slightly.

"Fang Han got started, it seems that he failed to place it twice in a row, and Solis's state has also been affected. ”

Zhang Jiahao said in a low voice.

"After all, it is a demonstration operation, and the pressure on Solis is still relatively high. Wang Zhicheng nodded.

Demonstration surgery can be a bit stressful for doctors.

If it is a simple minor operation, it will naturally be a personal show and a stage for a big man like Solis, but if the operation is too difficult and there are continuous accidents, even Solis's mentality will fluctuate.

This is also the reason why the live broadcast equipment is very mature now, but many surgeons still do not choose live surgery.

The personal show is welcomed by many doctors to make themselves famous, but once there is an accident, it will bury their fame.

The little doctor is okay, especially a famous doctor like Solis, the greater the impact.

If the internal surgery really fails, as long as it is not due to human reasons, it is unavoidable, and the hospital will not publicize it, and the impact is only small.

But demonstration surgery, even if the hospital wants to cover it up, it can't cover it up.

Even if the operation is not violated, it is a normal operation, and the failure is within the normal factors, but failure is a failure.

Either Caesar or nothing.

For famous doctors, if you fail, others will only think that you are incompetent.

"Put it in!"

Someone in the main venue spoke.

"Once successful, this Fang Han is really amazing. ”

"Put it in, Xiao Fang is amazing. ”

Wang Zhicheng couldn't help but admire.

"Have you noticed, Fang Han's hand is very steady, and the time is very accurate, Solis can't compare to this point. Zhang Jiahao commented.

Wang Zhicheng nodded, not only Zhang Jiahao could see this, but many doctors could see it.

In fact, Fang Han's hand is indeed more stable than Solis, and the timing is also very accurate, neither fast nor slow, so that he can succeed at one time.

Of course, this is also related to Fang Han's observation of Solis's two placements, Solis failed to place twice, and Fang Han looked at them closely, so the third time there was an obvious reference.

At the same time, the martial arts extracted by the system have also improved Fang Han's physical fitness greatly, whether it is reaction or all aspects, Solis is indeed not as good as Shang Han.

"I put it in, and I don't know if the location is appropriate. ”

"It's still okay to move in a small area, and it's amazing to have it done right the first time. ”

In the operating room, Fang Han and Solis looked at the location and discussed in a low voice.

"The position of the lamination should be okay, you can jump first to see the ultrasound ......," Fang Han asked Solis.

"Yes, if there is a problem, you can stop jumping again and adjust it slightly. Solis nodded.

"Prepare for the rejump. Fang Han's voice sounded in the operating room.

: I'm not in good shape, so I'll be on a shift today!
