This classmate opened his eyes again.

Turning his head and looking at the clues on her husband's face, Ye Sujin thought about the information she called her last time and revealed: It seems that this husband might really be snatching him with his sons.

"How?" Ye Sujin asked about the opinions of the big boss's husband. She was anesthesia and didn't understand some surgical techniques very well.

On the stage, it was surprisingly quiet.

After her second son was replaced by the position of the main surgeon, she almost didn't say a word, making her unable to figure it out.

The wife of anesthesiology master, you can't say that you can't understand the tricks at all, otherwise you wouldn't ask such questions. Cao Yudong knew this and told his wife: "Look at it quietly, don't disturb the child to count."

It is said that this surgery is the most important and difficult in this place. It is definitely not just a "small" operation, but a technical level.

Where is the level? Carefully recalling the surgical process and purpose introduced before, you will find that this operation uses a single ventricle (right ventricle) to supply blood to both sides of the body's pulmonary artery, which inevitably involves a distribution ratio issue.

There is only one ventricle left, and is it appropriate to share the ratio of blood to the aorta and the lung aorta?

It is definitely not a simple and crude algorithm like fifty to fifty.

The systemic circulation requires that the heart pumps out more blood flow each time than the lung circulation. For example, the aorta of a normal healthy person is thicker than the diameter of the pulmonary aorta, which is common sense.

Some people say that the distribution ratio is sixty to forty, or dozens to dozens.

There is no absolute conclusion about this value. The physical condition of each person is different, and the doctor needs to adjust it according to the actual situation of the surgery. It should be mentioned here that this disease includes the baby who is undergoing surgery now that it is very common for pulmonary hypertension to accompany it. However, the baby's good luck is that the pulmonary hypertension has not reached the critical value that triggers the Fonton surgery. It is equivalent to saying that if the doctor suddenly corrects all the pulmonary hypertension, the baby is afraid that the body may not be able to adapt to it in a short period of time and will have problems. Therefore, this surgery is called palliative surgery, which is not to completely cure the problem of pulmonary hypertension.

Doctors need to comprehensively measure these factors when considering final decisions.

After deciding the distribution ratio between the two, the doctor will make the thickness ratio of the blood vessels on both sides as much as possible to complete the precise distribution.

Cao Yudong calmly said that letting his child think about numbers was based on his performance of seeing classmate Xie, and he thought that these problems would not be difficult for her.

All kinds of estimates are her strengths. Perhaps because of this, Xie Wanying did every step very steadily.

When choosing the right model of artificial duct to connect the pulmonary artery to the right ventricle, she was quite confident that she could get it in one step.

It is safe. If it were other surgeries, it would undoubtedly help her save a lot of surgery time. However, today's surgery is too easy to cause fatigue.

Xie Wanying did the same thing. She looked up and looked at the electronic clock hanging on the wall. Every second she showed was shocking when the clearly beating red numbers on it were shocking.

Before she knew it, the operation time was approaching its limit, almost sixty minutes, which was completely beyond her own estimate.

The anxiety that filled her heart had never tried before.

In Zhu Xing's surgery last time, she was also close to the limit of time, and she was not stressed. This time, her identity became the main surgery, and the key step was that she did it. Before the operation, she persuaded her family to let her children have the surgery. If it fails—
