Rebirth in the medical world

Chapter 487
When the knife went down, a lot of blood gushed out immediately.

"Add five units of blood coagulation factor!" Ouyang Chenhui didn't raise his head. Just now when Al was recovering from hibernation, he used too much anticoagulant. At this moment, the blood is in a low coagulation state, which is not good for hemostasis. Therefore, he He lowered his head and calmly clamped the blood vessel with a hemostat, while pressing hard with gauze to stop the bleeding, and at the same time gave a verbal doctor's order!
During the operation, the oral doctor's order is valid, so after hearing the order, the roving nurse immediately added five units of coagulation factor to Al's intravenous infusion bottle!

With this series of actions, the bleeding surface has been controlled, and the bleeding speed has also slowed down. Ouyang Chenhui began to look for the next entry point this time!

Al's heart had serious adhesions, so it was very laborious to separate these adhesions!Fortunately, Ouyang Chenhui has dual perspective eyes, so when the time comes, he only needs to concentrate on taking a look, and then cut down. Although it is very dangerous, it does not hurt the surrounding blood vessels and nerves!
Ouyang Chenhui was the chief surgeon, and the three cardiologists were his assistants just now. Seeing how quickly Ouyang Chenhui cut the knife every time, they all opened their mouths in surprise, but seeing him every time without any danger, They were once again impressed by Ouyang Chenhui's surgical skills. You must know that they are basically in their 50s and [-]s, and the time spent on the operating table may be quite old. With such a heart, they dare not take it lightly!Unexpectedly, Ouyang Chenhui was so skilled at such a young age, so when they looked at Ouyang Chenhui, they couldn't help but feel a little more searching!

According to the surgical steps of heart transplantation, there are three steps to remove the recipient's heart: the first step, median sternotomy incision.Heparin 300U/kg was injected intravenously to establish extracorporeal circulation.In the second step, the anterior wall of the left and right atrium was resected, and the posterior wall of the left and right atrium and part of the atrial septum were reserved for anastomosis.The third step is to cut off the aorta and pulmonary artery close to the semilunar valve.

Although the process of separating the heart was very tortuous, it was safe and sound.
When part of Ai Er's heart was separated, Su Chun felt his whole body trembling, saying that his body was skinny and pointing at his parents. Seeing Ai Er's heart being held by Ouyang Chenhui in his hands, he suddenly felt Felt creepy feeling!
Al's heart didn't last long in Ouyang Chenhui's hands. Al's heart was removed, and the power system responsible for the blood circulation of the whole body was gone. Therefore, at this time, the extracorporeal circulation must be connected as soon as possible. Machine, this is also a temporary method to ensure that the donor heart is not functioning in the recipient!

After connecting the extracorporeal circulation machine, Ouyang Chenhui began to transplant Betty's heart into Al's heart cavity. This is the last step, but it is also a step that he dare not take lightly.

Ouyang Chenhui first used three-zero absorbable sutures to anastomose the left atrium, then similarly used three-zero absorbable sutures to anastomose the right atrium, and then replaced it with four-zero absorbable sutures The aorta and pulmonary artery were anastomosed at the end, and the heart transplant was basically completed.

However, at this moment, Ouyang Chenhui suddenly felt a premonition that he didn't want to, and then, he heard the urgent voice of the anesthetist: "Dean Ouyang, the blood pressure has dropped!"

The exclamation of the anesthetist made everyone's heart beat faster involuntarily. Even Ouyang Chenhui, who had always been calm, suddenly became nervous. Bar?

"Five milligrams of epinephrine!" Ouyang Chenhui said quickly while staring at the numbers on the ECG monitor.

Although the doctor's order was given, Ouyang Chenhui did not hope for the effect of adrenaline at this time!
Sure enough, after the adrenaline was added, the blood pressure did not rise as expected. Although the rate of drop was a bit slow, it was still falling!

"Dean Ouyang, blood pressure is still dropping!" The anesthesiologist's voice trembled a little!You know, this is a major operation, and not only the people at the scene, but also dozens of experts outside are watching!
Indeed, when something happened in the operating room here, the medical staff who were facing the big screen in the other operating room also secretly sweated!

Su Chun's whole body began to tremble. As a senior medical system researcher and official, his performance at this time is really unflattering, but everyone can understand his mood. The life and death on the stage is his daughter!

"Ouyang, what's the situation?" Su Chun asked after calming down a little.

"It might be internal bleeding. I suspect it's a ruptured anastomosis..." Ouyang Chenhui replied, while looking at the anastomosis of the heart!

Seeing this, his spine felt chills. It turned out that there was a hole about two centimeters long on the back of the anastomotic stoma of the aorta, which was bleeding out!

"Blood urgently, prepare for extracorporeal circulation again!" Ouyang Chenhui's voice was loud!After finishing speaking, he had already crossed several vascular clamps to block the bleeding hole!
After intense and orderly preparations, Ouyang Chenhui finally resolved the crisis!

After the stitching was completed, Ouyang Chenhui carefully observed every unit that might be bleeding, and after confirming that there was no problem, he began to prepare to remove the extracorporeal circulation machine!

The exciting moment is coming. After the extracorporeal circulation machine is removed, the blood in Al's body will flow through Betty's heart, thus completing the whole process of blood circulation!It also marks the beginning of a new heart at work in Al!

Seeing the blood slowly ejected from the left ventricle through the aorta to all parts of the body, after a circle, it was recovered through the pulmonary artery, after one cycle, Ouyang Chenhui's hanging heart was relieved!

"Ouyang, how's it going?" Su Chun's voice was full of anticipation. He didn't even have the courage to see this exciting moment in person!

"Uncle Su, it's a success! It's up to Al next!" Ouyang Chenhui said excitedly!

Next, there will be a period of rejection. At that time, Al will take some anti-rejection drugs. If nothing happens for a while, Betty's heart will be completely integrated with Al's body!
Su Chun nodded excitedly, but couldn't say a word!
When Ouyang Chenhui started to prepare to close the chest cavity for the final suture, the operating room next door was already boiling!
