"It's a little troublesome!"

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

The previous mechanical valves fell off but did not fall off completely. The roots and the annular wall were firmly stuck, which was quite troublesome.

It has not completely fallen off and is sticky tightly, so you can't use brute force.

This is the heart, not breaking steamed buns or cutting vegetables. If you use a little force, it will cause heart damage, and it will be a big problem.

At the same time, because the patient's heart is much larger than that of ordinary people, and the petal height of the new memory metal version is 4.5, the incision is chosen at 4.5. At such a long position, it is difficult to locate, and it is difficult to separate the adhesion part.

"This separation is quite difficult."

"Yes, you have to be careful."

The doctors watching the operation were talking.

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

"In this case, there are only a few domestic major hospitals such as Yanjing, Union, and Shanghai. Doctor Solis must be fine."

In the operating room, Solis's face was calm and he whispered to Fang Han.

"Electric knife, 20 electric cutting and electrocoagulation!"

Fang Han's voice rang in the operating room.

"Bar 31 line!"

Solis carefully stripped off the old artificial mechanical annular annex.

"Vascular forceps!"

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

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

The roots of the artificial valves and the annulus wall are very tightly sticky. You must be careful when separating. Any pulling will cause damage to the heart. This separation is also a difficult point in the operation.

"Take it out!"

"It was taken out smoothly."

After about ten minutes, Solis successfully removed the old artificial flap, and both the operating room and the doctors who were watching the operation breathed a sigh of relief.

"The artificial flap was taken out, but it is still difficult to operate next."

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

“Yes, it’s not easy to place.”

"The original aortic valve was very severely tear-out, so there was not enough tissue to provide support for the new metal valve."

Zhang Jiahao and Wang Zhicheng also analyzed.

As a top domestic off-psychiatric expert, the fastest way to make progress in the process of this kind of surgery is constantly analyzing the difficulty of the surgery, thinking from the perspective of others, and then watching other people's surgery.

Just as Fang Han said to Li Xiaofei and others before, as a new doctor, you must not be afraid. When you can participate, try to express your opinions as much as possible, not be afraid of mistakes or be scolded.

As a new doctor, there are few opportunities to get started, and some people check it. At this time, even if the opinions are wrong or the opinions are incorrect, there will be no serious consequences. At most, they will be scolded by the attending officer.

But this kind of opportunity is very difficult. Even if you are wrong or scolded, the lessons will be deeply imprinted in your mind.

As the saying goes, failure is success. As a doctor, in actual treatment and operation, we must avoid making mistakes as much as possible or making fewer mistakes. However, before practice, we can completely put ourselves in it and consider how to treat ourselves as the main treatment and why we treat it like this...

"Diameter 25 mm, metal flap preparation."

After the measurement, Solis whispered to Fang Han, and Fang Han promptly gave instructions to the instrument nurse beside him.

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

This memory metal valve is usually stored in a low temperature of zero to minus four degrees Celsius. This memory metal valve will be compressed at a low temperature and will expand automatically once ice water is taken out.

Of course, this attribute is also the reason why memory metal valves do not need to be sewn. However, due to the characteristics of metal valves, the difficulty of placement has also increased greatly.

You must be very careful where to place it and how it should be placed, because the metal flap expands and it is quite difficult to place it.

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

For them who have experienced a surgery waiting, this time their hearts are more worried than the last time.

The difficulty and risk of this operation are so high that the doctors have already made it clear before the operation.

Even if the surgeon is Solis, the doctors will explain the risks and consequences of the surgery to the patient's family as in detail as possible, which also makes Zhou Chen's parents even more worried and afraid.

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

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

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

“The placement failed!”

In the operating room, Solis failed to place the first time and quickly took out the metal flap.

“Recompress!”

Fang Han handed the removed metal petals to the doctor and nurse beside him.

When the metal valve is taken out cold water, it will expand in a short time, so the doctors don’t have much time to give them much time and must be placed in a short time. If the time is delayed too long and the metal valve expands, it will not be placed in. However, in such a short time, the doctor does not have much time to consider the position, and the position of the placement is prone to deviations. If the placement fails, it must be taken out immediately and placed in a secondary manner.

After taking it out, the metal flap should be put in cold water again for compression and a second attempt should be made.

"Failed, failed to place the first time."

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

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

"It has been forty minutes since the extracorporeal circulation was established?" a doctor asked.

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

"It's been one-third of the time, and if the continuous placement fails, it's troublesome."

"But there is no way to do this. In addition to the experience of seeing a doctor, it also depends on luck."

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

The position of memory metal valves must be appropriate. If placed too high, it will affect the normal coronary artery opening, leading to very severe acute heart failure. The patient may not be able to get off the operating table. If placed too low, it will easily damage the structure in the heart ventricular and cause conduction block.

“Failed again!”

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

"Two failed consecutively, there is not enough time!"

Zhang Jiahao whispered to Wang Zhicheng.

In principle, the extracorporeal circulation time cannot exceed two hours, but two hours is the limit. After placing the metal flap, it does not mean that the operation is over. The subsequent time will appear very tight. If something happens again, it is very likely that the time will be exceeded.

"Doctor Solis, I'll do it."

Fang Han whispered to Solis, speaking in English.

Solis nodded slightly.

"Fang Han got it. It seems that the failure to place it twice in a row, and Solis's condition has also been affected."

Zhang Jiahao whispered.

"After all, it's a demonstration operation, and Solis is under a lot of pressure." Wang Zhicheng nodded.

Demonstration surgery will be somewhat stressful for doctors.

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

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

Personal show is welcomed by many doctors, to make yourself famous, but if an accident occurs, it will ruin your fame.

The little doctor is fine, especially the famous doctors like Solis, the greater the influence.

If internal surgery really fails, as long as it is not human-made, it will be inevitable. The hospital will not promote it, and the impact will only be small.

But even if the hospital wants to cover up the demonstration surgery, it cannot be covered up.

Even if the operation does not violate the rules, it is a normal operation and failure is within normal factors. However, if it fails, it means failure.

Success and defeat of the enemy.

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

"Put it in!"

Someone spoke out at the main venue.

"Once a success, this Fang Han is really amazing."

"If you put it in, Xiao Fang is amazing."

Wang Zhicheng couldn't help but exclaim.

"Have you noticed that Fang Han's hands are very stable and his time is very accurate. Solis cannot compare to this point." Zhang Jiahao commented.
