Returning to ’90s, She Became Famous in Major Surgical Fields

   Chapter 2788 [2788] Can't help her

   This classmate was an eye-opener for him again.

   Turning her head to glance at the clues on her husband's face, Ye Sujin remembered the information revealed by her husband on the phone last time: It seems that this husband might really want to win over with his sons.

   "How?" Ye Sujin asked about the opinion of the big surgeon's husband. She is anesthetist and doesn't understand some surgical procedures.

  On the stage, it was surprisingly quiet.

  After the second son was replaced by the chief knife and became an assistant, he hardly said a word, causing her to wonder.

   Mrs. Mrs. Anesthesiology, I can’t say that I don’t understand the way, otherwise I wouldn’t ask such a question. Cao Yudong knew this and told his wife: "Be quiet and don't make the child want to count."

   It is said that this operation is the most important and most difficult in this place. It is definitely not just a "small" operation that is difficult, 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 pulmonary artery, which inevitably involves a problem of distribution ratio.

   There is only one ventricle left, so what is the appropriate ratio of blood to the aorta and the pulmonary aorta?

   is certainly not such a simple and crude algorithm of fifty percent to fifty.

   The systemic circulation requires more blood flow than the pulmonary circulation pumped by the heart each time. For example, the aorta of a normal healthy person is thicker than the diameter of the pulmonary aorta. This is common sense.

   What is the distribution ratio? Some people say that 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 it according to the actual situation of the operation. It should be mentioned here that it is very common for this disease, including this baby who is currently undergoing surgery, to have pulmonary hypertension. It's just that the baby is lucky that the pulmonary hypertension did not reach the critical value to trigger the Fonton operation. It is equivalent to saying that if the doctor suddenly corrects all the pulmonary arterial hypertension, the baby is afraid that the body may not be able to adapt to it in a short time, but it will go wrong. Therefore, this operation is called palliative surgery, not to completely cure the problem of pulmonary arterial hypertension.

   These factors need to be taken into consideration by the physician when considering the final decision.

   After determining the distribution ratio of the two, the doctor will try to achieve this thickness ratio of the blood vessels on both sides as much as possible to complete the precise distribution.

  Cao Yudong calmly said that letting the children think of numbers is based on seeing the performance of Xie classmates, and believes that these problems cannot be difficult for her.

   Various estimates are her forte. Maybe because of this, Xie Wanying did every step very steadily.

   When choosing the right type of artificial tube to connect the pulmonary artery to the right ventricle, she was quite confident that she could do it in one step.

  Stable, if she had other operations, it would undoubtedly help her save a lot of operation time. However, today's surgery is too easy to produce fatigue.

  Xie Wanying did almost the same. She raised her head and glanced at the electronic clock hanging on the wall. Every second displayed by the clear beating red numbers on it was shocking.

  Unconsciously, the operation time was approaching to the limit, almost 60 minutes, completely beyond her own estimation.

   The anxiety that filled her heart had never been done before.

   She served as an assistant in Zhu Xing's surgery, which was also approaching the time limit last time, so there was no pressure. This time, the identity has become the main surgeon. She does the key step. Before the operation, she persuaded the family to let the child have the operation. If it fails—
