Chapter 1062

Qi Hong, holding the operating forceps, stares at the heart on the blue cloth platform. Different from the heart in the same position in previous operations, the heart is still beating. It seems that he has his own consciousness and is showing vigorous vitality to everyone in the room.

Her hand stretched forward two times eagerly, and then it was directly fixed in the air. The bright eyes on the surgical mask directly glanced at Miss Dongfang who was encouraged by her side, showing an apologetic expression, and then directly expressed to Gu Ning and Chen Qun, the main knife.

"I'm really flustered. My hands are shaking. Can I be an apprentice and watch you operate?"

No matter Chen Qun or Gu Ning was surprised by the reaction of the female Xueba. After all, not every doctor can come across this kind of extracorporeal heart surgery. Even the experienced chief physician and deputy chief physician may not be able to cope with it. What's more, Qi Hong, who is not very good at it?

What's more, Chen Qun and Gu Ning found the heart problem at this time, which was much more than what was shown in the MRI and CT photos. If Qi Hong was allowed to complete it again, it would be irresponsible.

Gu Ning nodded directly, "then you go down. In fact, you don't have to say that we won't let you take over. After all, this operation has already exceeded your ability, even more than the situation calculated by three-dimensional projection. You can't do it just because the tendrils of the tumor invade the right atrial wall

Chen Qun also added.

"And the tumor on the heart is so widespread that we need to remove more tissue, which means there is not enough tissue to reconstruct the inflow cavity of the patient's heart."

Gu Ning came over to take over the position of Qi Hong and discussed with Chen Qun.

"Maybe we can try it with expanded polytetrafluoroethylene?"

"No, the rest of the atrium is not enough to connect the blood vessels."

"We can use the next room to complete the connection."

"It doesn't seem to work either. See, there are dense conductive fibers on the spacer. If there is damage, it will lead to arrhythmia. Now, we need to immediately come up with a perfect way to complete the operation, otherwise, too long bypass operation will lead to hypotension and abnormal bleeding

"Prepare platelets and fresh frozen plasma immediately, and be ready for blood transfusion at any time. Maybe we can reconstruct the ventricular wall with the submucosa of small intestine, but the material is limited to cover such a large area. It seems that today's surprise is one after another, only one problem has been solved, and then a new problem has appeared in the solution. If it goes on like this, we will be exhausted. "

Gu Ning, as the head of cardiology department and the top three experts in China, certainly knows that this kind of uncontrolled accident often means the failure of surgery.

Qi Hong is also thinking about this problem, can't help but say her views.

"Maybe, we can see how thick the deep fascia is. If it's more than two millimeters, maybe we can use this instead..."

"No, I've already thought about that. I can't completely cover the heart. We need 2.7 mm thick tissue that can fully meet the requirements of arterial perfusion and systolic blood pressure. We can't find such tissue in patients, so we need to break the routine and search for materials from other ways. "

Chen Qun frowned and came to a conclusion.

As soon as his voice fell, Zhou Lin, who was watching the video from a distance, immediately sighed.

"If it's just a heart valve transplant, we can use a bovine pericardium transplant."

Gu Ning sighed.

"Unfortunately not, the endurance of bovine heart tissue is not enough to complete the whole heart."

In a few questions and answers, Dongfang Wenxin, who has been responsible for controlling the computer, suddenly opens her mouth and gives a calculation result.

"Just now I searched for the organizations Chen Qun needed, and the little broom gave me several answers. The most suitable one is the pig bladder tissue, which fully meets your requirements. Moreover, in the organization procurement Laboratory of the hospital, there are just more than 10 organizations sent in the morning. If there are enough choices, I don't know whether they are suitable or not."

Gu Ning and Chen Qun look at each other, Gu Ning some heart said.

"Pig bladder is only used to reconstruct human bladder in urology department, but it has never been used in heart. Miss Xinda, do you have any examples of heart application in foreign materials. It's not limited to the bladder. Other organs are OK. I seem to have some impression, but compared with your database, I'd better wait for your result completely. "

Miss Dongfang quickly entered the search request on the keyboard. In less than a second, she got the result."Pig bladders have been used in more than ten operations on human hearts, but there are no cases of atrial wall building."

Chen Qun immediately made a decision, "then we'll be the first to eat crabs. We'll use the pig bladder to rebuild the patient's heart wall. Xiaoxin immediately sent a message to the organization procurement laboratory and asked them to send 300 cm pig bladder tissue to us as soon as possible."

While sending messages, Miss Dongfang did not forget to ridicule Chen Qun.

"It seems that the little broom will make contributions one day. After the operation, it should be rewarded with a big chicken leg, which is much smarter than some people with pig brains. This operation is called Chen's bladder construction! "

Dead girl is to be reasonable and unforgiving, deliberately angry with him, where there is such a nondescript, deliberately bladder to emphasize the naming method?

Chen Qun ignored the satire of the proud young lady and stood directly opposite Gu Ning and started the operation. Two meters away, the patient was lying quietly on the operating table with a blood hole on his chest. Looking down from above, it was really frightening.

Qi Hong, who is recording the video, quickly turns the picture to one side and doesn't continue to watch this horrible scene. A strange idea came to mind, that is, last time Chen Qun took out all the organs in the abdominal cavity of the patient and completed the operation. Now the abdominal cavity has changed into the chest, and the heart has been taken out. According to this trend, Chen Qun may take out the brain in the cranial cavity for operation.

It's horrible to think about it!

Just when the brain can be taken out for surgery, has technology evolved to the point of brain in a VAT? The real version of the matrix can be staged at any time.

Of course, with the current level of science and technology, Chen Qun has no way to remove his brain for surgery. Maybe in another 30 or 40 years, when they are all old, there will be a glimmer of hope. But the whole brain can't be taken out, but part of the brain can be taken out conditionally. It's just a big problem to keep the connection between brain and nerve. Maybe a few decades later, they will be able to complete the operation outside the cranial cavity of the local brain, perhaps under the electron microscope.

Just as Qi Hongdong thinks about it, Chen Qun's voice rings in the operating room.

"It's really very fast to perform surgery in vitro. I expect it will take ten minutes to peel off all the tumors, and it will be completed in six minutes. However, this operation has taught us a lesson, that is, the next extracorporeal heart surgery, it is best to place the operating table above the chest of patients to solve the problem of long-distance hypotension in bypass surgery. "
