The venous cannula is not completely fixed like the artery, but has a slight degree of movement that allows the doctor to move it up and down to adjust the insertion depth or shallowness. The outflow tube of a vein is different from an arterial tube. Without pumping power, there is a risk of poor outflow.
Based on this principle, Mr. Duan seized the opportunity to order the extracorporeal bypass specialist and the anesthesiologist to cooperate with each other to conduct a preliminary test of the parallel circulation during intubation. The so-called parallel circulation means that the patient's heart is started without stopping.
Extracorporeal circulation machine, in this case, the heart and extracorporeal circulation run together. If you turn on the machine in advance, you can check whether there is any bleeding or blood leakage at the intubation site and whether there is any blood flow problem. If there are no problems, stop the heart.
The operation lasted for about an hour and a half, and we reached the central step of incising the heart. Finally, we were able to incise the heart and examine the lesions.
Ah ~ everyone sighed.
It was not a partial rupture but a complete rupture. The situation was more serious than the preoperative examination and prediction. No wonder the child's heart was not right just during the operation. To be precise, it was not broken before the operation and then completely broken. This is a medical condition.
Suddenly it gets worse.
From the current autopsy case, Xie Wanying suddenly thought of her grandfather. It was possible that her grandfather was like this child and suffered an accidental injury, 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.
During the examination, no signs of heart disease were found for the time being. She thought that she had always speculated that her grandfather might have a congenital heart structure problem, and perhaps she needed to raise a new question mark.
My thoughts returned to the previous surgery. After opening it, I could see it clearly with my own eyes, and it was much easier for the doctor to repair it. The fairy brother's words were right, and there was no way to open the chest for exploration.
Cao Zhao received a glance from classmate Xie, who seemed to be very grateful to him, which made him, a god, almost puzzled: He seemed to have never done anything in the operation, so why should the students thank him.
Outside the operating room, Ren Chongda and Wei students appeared carrying cake cards and ribbon flowers.
When Zhu Huicang saw his old classmate bringing things over, he criticized: "What did you do when you brought it to the scene? What you have to do is pretend not to know and let her give it away."
"I know. Didn't she come out? I came here to find a frozen cake in the refrigerator. The cream on this cake may have melted quickly due to the high temperature in the car." Ren Chongda explained.
Cao Yong stood nearby and listened to the two of them talking, as if he, the client, did not exist.
The other two people did say this to him: "Turn aside and look at the wall and pretend not to see it."
Otherwise, how will he act as a surprise later? Can Cao Yong be a good actor?
Cao Yong had no choice but to find a place to sit down first, and take a look at the junior brother who was working together to save people tonight.
Classmate Wei was quite tired from running around after rescuing people tonight, so he took a tissue to wipe his sweat along the way.
"Have you eaten?"
Hearing Senior Brother Cao ask him this, classmate Wei Shangquan was stunned for a moment. He could feel that Senior Brother Cao was more attentive and considerate than the counselor. No wonder everyone in the class liked Senior Brother Cao.
"I'm going to buy you some food. You sit still." Cao Yong stood up and asked his junior brother to sit down.
Ren Chongda came to his senses: Oh, my students didn't have dinner. After giving the cake to Zhu Huicang's help, he hurriedly followed Cao Yong and ran out to buy food.
Zhu Huicang carried the cake to find the refrigerator, and also said to his junior brother who had not eaten: "Sit here and don't run around, lest you faint from hunger. We can't do rescue work in other hospitals."
