Chapter 2541 【2541】Great Opinion

Seeing Student Xie, the gentle classmate Pan didn't want to say anything, and took the initiative to explore the way ahead: "I think the most important thing is to fit."

If Liu Guang in Cao Yong's eyes nodded to his junior's answer, it seemed that many of his juniors were also talented.

In a nutshell, Pan’s words refer to the inappropriate places in the process of organ transplantation. Doctors may be able to use ingenious methods to make them suitable, called suitable.

"Yingying, what do you think?" Pan Shihua asked classmate Xie for his opinion.

Brother Cao and classmate Wei looked over as if they wanted to hear what she had to say. Xie Wanying said: "Where is the limit of suitable technology, where is the upper limit of organ transplant surgery?"

This is a further academic interpretation of Pan's words.

The eyes of classmate Wei and classmate Pan seemed to be lit up with little stars. The corners of Cao Yong's mouth couldn't agree with each other.

How to understand what Xie said?

Let me talk about the liver transplant operation I have seen before. At that time, classmate Xie participated in it to make suggestions. The difficulty for the doctors during the operation is due to the fact that the donor liver is too large and not suitable, so it needs to be cut down. This is a matter of suitability.

The donor-to-recipient ratio has always been a basic threshold in all organ transplant operations.

Liver transplantation has such technical difficulties, and it is the same in heart transplantation.

Is it like a liver transplant, where the heart donor is too big to be cut down to fit it? Classmate Xie told reporter Li that, for example, the proportion of the donor heart in pediatrics can be as large as 2.5 times the size of the recipient's original heart.

Regarding this crux, as long as there is a little common sense of anatomy, the heart cannot be like the liver. The shape, function and structure of the two organs, the liver and the heart, are all different in all aspects.

The overall structure of the heart and its function are closely related. The liver is not, the function of the liver mainly depends on the liver tissue. This results in a donor liver that can be cut in two to serve two recipients. How is the heart possible. The heart-to-donor ratio is really stricter than liver transplantation. Let me talk about some cold knowledge here. For liver transplantation, the donor is not afraid of being too small. Contrary to the heart, as Xie said, the ratio of the pediatric donor heart should not be less than 0.9 of the recipient's original heart. It shows that the acceptability of the small donor ratio is much lower for heart transplantation than for liver transplantation.

Why is this?

The main functional output of the heart is the recycling of blood throughout the body. It is not too scary to have a larger donor, because many patients who need heart transplantation have heart disease, which causes the expansion of the myocardium and the size of the heart becomes larger. Of course, it can't be outrageously large, as it will also cause secondary hypertension and other problems after surgery.

In contrast, the problem caused by too small a donor is more difficult to solve: low cardiac output. Many heart disease patients are trapped in this problem at the end stage. If the transplanted heart fails to solve this important problem, the result is likely to be a waste transplant.

In clinical practice, it becomes: young children try to choose older donor hearts. A female patient selects a male patient heart. When a male patient accepts a heart that is too much smaller than his body weight, he should be more cautious.

These are exactly the "suitable" technical limits pointed out by Xie that determine the technical limits of organ transplantation, and they are all difficulties that need to be solved in the operation.

The threshold for heart transplantation is higher than that of liver transplantation alone. Heart transplantation is definitely more difficult than liver transplantation, otherwise I would be sorry for the titles of the two major surgical specialties.

Thank you for your support! ! ! good night dears~
