Turning her head to take a look at the clues on her husband's face, Ye Sujin thought about the information her husband had revealed to her last time on the phone: It seemed that this husband might really be competing with his sons.
"How is it?" Ye Sujin asked for the opinion of her husband, a big surgeon in surgery. She was an anesthetist and did not understand some surgical techniques.
On stage, it was surprisingly quiet.
After her second son was replaced as the chief surgeon and became an assistant, he barely said a word, leaving her confused.
The wife of an anesthesiology expert cannot say that she does not understand the rules at all, otherwise she would not ask such a question. Cao Yudong knew this and told his wife: "Be quiet and watch, don't disturb the child to count."
It is said that this operation is the most important and difficult in this place. It is definitely not just a "small" operation that is difficult, but also a technical hurdle.
Where is the checkpoint? If you carefully recall the surgical process and purpose introduced before, you will find that this surgery 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.
With only one ventricle left, what is the appropriate proportion of blood to be distributed to the aorta and pulmonary aorta?
It's definitely not a simple and crude algorithm like 50% versus 50%.
The systemic circulation requires more blood flow pumped by the heart each time than the pulmonary circulation. For example, the diameter of the aorta in a normal healthy person is larger than the diameter of the pulmonary aorta. This is common sense.
What is the distribution ratio? Some people say it is sixty to forty, or several dozen to several dozen.
There is no absolute conclusion on this value. The details of each person's physical condition are different, and the doctor needs to adjust according to the actual situation of the operation. One thing to mention here is that it is very common for this disease, including the baby currently undergoing surgery, to be accompanied by pulmonary hypertension.
It's just that this baby is lucky that the pulmonary hypertension does not reach the critical value that triggers fonton surgery. It is equivalent to saying that if the doctor suddenly corrects all the pulmonary hypertension, the baby may be afraid that the body may not be able to adapt in a short time and something will go wrong.
.Therefore, this surgery is called palliative surgery and is not intended to completely cure the problem of pulmonary hypertension.
Doctors need to weigh all of these factors when considering their final decision.
After deciding the distribution ratio between the two, the doctor will try to achieve the same thickness ratio of the blood vessels on both sides to complete the precise distribution.
Cao Yudong calmly said that he should let the children think of numbers by themselves because he had seen Xie’s performance and thought that these problems would not be difficult for her.
Various estimations are her strong point. Perhaps because of this, Xie Wanying does every step very steadily.
When choosing the appropriate type of artificial tube to connect the pulmonary artery and the right ventricle, she was quite confident that she would get it right in one step.
Sure, it would undoubtedly have saved her a lot of time in other surgeries. However, today’s surgery was too easy to cause fatigue.
Xie Wanying did the same thing. She raised her head and glanced at the electronic clock hanging on the wall. The clearly beating red numbers on it displayed every second that was shocking.
Unknowingly, the operation time approached the limit, almost sixty minutes, completely exceeding her own expectations.
The anxiety that filled her heart was something she had never experienced before.
She served as an assistant in Zhu Xing's last surgery, which was also approaching the time limit, and there was no pressure. This time she became the chief surgeon, and she did the key steps. Before the operation, she persuaded the family to let the child have the operation. If it failed--
