The venous cannula can be not completely fixed like the artery, but a little bit of movement can allow the doctor to move up and down to adjust the depth or shallow insertion. The vein has a different outflow tube and the arterial tube. If there is no pumping force, you will be afraid of poor outflow.

Based on this principle, the genius of Duan seized the opportunity to order the extracorporeal circulator and anesthesiologist to cooperate to conduct the part of the parallel circulation during intubation. The so-called parallel circulation means that the patient's heart is turned on without stopping.

Extracorporeal circulation machine, in this case, the heart and extracorporeal circulation are running together. Turning the machine in advance can detect whether there is bleeding at the lower intubation and whether there is any blood leakage or blood circulation. If there is no problem, the heart will stop beating.

The operation time refers to an hour and a half, and the central step of incision of the heart, and finally the heart is cut to see the lesion.

Ah~ Everyone sighed.

It is not partially broken, but completely broken, the situation is more serious than preoperative examination and estimates. No wonder the heart of the child was not right during the operation. To be precise, it was completely broken before the operation, which is a condition

Suddenly it worsened again.

From the current case of dissection, Xie Wanying suddenly remembered her grandfather. Is it possible that her grandfather would have suffered accidental injuries like this child, but her family and her were unaware of it. After she was reborn, she repeatedly told her mother to take her grandfather to the hospital.

After the examination, she had not seen any signs of heart disease along the way. I think she had always speculated before that her grandfather might have problems with the congenital heart structure and might need to give a new question mark.

My thoughts returned to the operation before me. I saw it clearly with my own eyes. It was much easier for the doctor to start repairing. The immortal brother said it was right, so I could open my chest and investigate it.

Cao Zhao received a glance from classmate Xie. People seemed to be very grateful to him, which made him wonder: he seemed to have never taken action during the operation since then, so why did the students ask them to thank him?

Outside the operating room, Ren Chongda and Wei appeared with cake cards and ribbon flowers.

When Zhu Huicang saw his old classmate bringing the things, he criticized: "What you have to do when you take them to the scene? What you have to do is pretend that you don't know and ask her to give it to you."

"I know. Didn't she come out? I came up to find a freezer frozen cake. The butter on the cake may have been a little higher in the car and it will soon melt." Ren Chongda explained.

Cao Yong stood beside him and listened to the two of them talking as if he did not exist.

The other two did say to him like this: "You go around and look at the wall and pretend you didn't see it."

Otherwise, how can he play surprise later? Can Cao Yong be a good actor?

Cao Yong had no choice but to find a place to sit first, and by the way, he looked at the junior brother who saved people together tonight.

It was quite tiring to save someone outside tonight and run around and then run around. I took a tissue to wipe my sweat all the way.

"Did you have a meal?"

When Wei Shangquan heard Senior Brother Cao ask him this, he was stunned for a moment. He could feel that Senior Brother Cao is more careful and considerate than the counselor. Don’t blame everyone in the class for his favorite Senior Brother Cao.

"I'll go buy some food for you. You can sit down." Cao Yong stood up and told his junior brother to sit down.

Ren Chongda came to his senses: Oh, his student didn't have dinner. After stuffing the cake to Zhu Huicang for help, he hurriedly followed Cao Yong to buy food.
