Unlike arterial cannulae, venous cannulae are not completely fixed, but have a little mobility to allow doctors to move them up and down to adjust the depth or shallowness of insertion. Veins are outflow tubes, which are different from arterial tubes. If there is no pump force, there will be a fear of poor outflow.
Based on this principle, Duan was a genius in this step. He immediately ordered the cardiopulmonary bypass technician and anesthesiologist to cooperate and conduct some advance tests of the parallel circulation during the intubation. The so-called parallel circulation means that the patient's heart is turned on without stopping the cardiopulmonary bypass machine, so that the heart and cardiopulmonary bypass can operate together. Turning on the machine in advance can detect whether there is bleeding or blood leakage at the intubation site, and whether the blood flow is not smooth, and at the same time start to cool the heart. If there are no problems, the heart will be stopped.
The operation lasted exactly one and a half hours, and it reached the central step of cutting open the heart. Finally, the heart was cut open to examine the lesion.
Ah~ everyone sighed.
It was not a partial rupture but a complete rupture. The situation was more serious than the preoperative examination and estimation. No wonder the child's heart was not right during the operation. To be precise, it was not completely broken before the operation but was completely broken afterwards. It was a sudden deterioration of the condition.
From the autopsy case, Xie Wanying suddenly thought of her grandfather. Is it possible that her grandfather suffered an accidental injury like this child, but her family, including her, did not know about it? After she was reborn, she repeatedly asked her mother to take her grandfather to the hospital for examination, but no signs of heart disease were found along the way. She thought that she had always speculated that her grandfather might have a congenital heart structure problem, and perhaps she needed to re-question it.
My thoughts returned to the surgery. After opening it, I could see it clearly with my own eyes, and it was much easier for the doctor to repair it. What the fairy brother said was right. If it doesn't work, I have to open my chest for exploration.
Cao Zhao received a glance from classmate Xie, who seemed to be very grateful to him, which made this god-like person almost puzzled: he seemed to have not played a role in the operation from beginning to end, so why did the student want to thank him?
Outside the operating room, Ren Chongda and Wei appeared with cake cards and ribbons and flowers.
...
...
When Zhu Huicang saw his old classmate bringing the things, he criticized her: "Why did you bring them to the scene? What you should do is pretend that you don't know and let her deliver them."
"I know. Didn't she not come out? I came up to find a frozen cake in the refrigerator. The cream on the cake might have melted quickly due to the high temperature in the car." Ren Chongda explained.
Cao Yong stood by and listened to the two of them talking as if he, the person involved, did not exist.
The other two actually said to him: "Turn away and look at the wall, pretend you didn't see it."
Otherwise, how can he act the surprise later? Can Cao Yong be a good actor?
Cao Yong had no choice but to find a place to sit down first, and by the way, take a look at the junior fellow apprentice who had rescued people with him that night.
Student Wei was quite tired after running around tonight in addition to rescuing people, and he wiped his sweat with a tissue all the way.
"Have you eaten yet?"
Hearing Brother Cao ask him this, Wei Shangquan was stunned for a moment. He could feel that Brother Cao was more careful and considerate than the counselor. No wonder everyone in the class liked Brother Cao.
"I'll go get you some food. Just sit still." Cao Yong stood up and told his fellow apprentice to sit down.
Ren Chongda came back to his senses: Oh, my students didn't have dinner. After stuffing the cake to Zhu Huicang to help take care of it, he hurriedly followed Cao Yong out to buy food.
Zhu Huicang carried the cake and went to find the refrigerator. He also said to his junior fellow student who had not eaten yet, "Sit here and don't run around. Otherwise, you will faint from hunger and it will be difficult for us to rescue you in other hospitals."
