"How low is the body temperature now?"

"Anal temperature 20 degrees!"

"No, it's too high, let the body temperature drop to 15 degrees. I'm ready to cut the aortic arch!"

"Hey, I see!"

Professor Uchimura instructed his assistants and subordinates to cooperate with his own operation, while on the other hand, he was fully absorbed in the stopped heart in front of him. When Professor Uchimura stretched out his hand, the nurse in charge of delivering the instruments immediately handed him the scalpel, and after taking the scalpel, Professor Uchimura cut the connection between the patient's aortic arch and the descending aorta.

"No, the vision is blurred, hurry up and clear the vision, I have to start preparing for the repair of the aortic wall and the replacement of the artificial arterial arch!"

"Hey, I'm so sorry!"

After the assistant used the suction device to suck out the outgoing blood, Professor Uchimura continued to work on repairing the arteries!

"Start timing me, I'm going to fix the blood vessel wall in five minutes!"

"Start the timer, five minutes!"

As the timer began, Professor Uchimura gradually quickened the movement of his hands. He forced himself to pour his whole body into the heart in front of him, trying not to think about what had just happened. For a cardiac surgeon, every surgery carries a huge risk. As the saying goes, there is no turning back from the bow, and as long as the operation of cardiac surgery begins, you can only grit your teeth and persevere. And Professor Uchimura is now in a race against death, as long as his hand movements can be faster, then there will be a better chance of his heart regaining its beating after a while.

"The aortic wall correction is complete, and now we will start to insert the artificial aortic arch into the quasi-aortic arch, and prepare a 4-0 line for me!"

"Hey, I see!"

"You two, now fully assist me in suturing the artificial aortic arch!"

"Hey, got it!"

"How many minutes?"

"Four minutes and thirty seconds, it's been 20 minutes since the heart stopped!"

"No, we have to hurry!"

Although Professor Uchimura was in a hurry, the surgical forceps holding the suture needle were still very stable, and I saw that he skillfully used the suture needle to carefully suture the aorta and the artificial aortic arch together, while the two assistants tried to cooperate with Professor Uchimura's movements. Before you know it, a layer of sweat is drenched on everyone's foreheads.

"Wipe your sweat, how long has it been now?"

"It's been 24 minutes!"

"Okay, everybody, work harder, and start restoring the blood supply to the heart in five minutes, understand?"

"Understood!"

With an inspiring shout coming from the operating room, Professor Uchimura began to replace the ascending aorta.

Replacement of the ascending aorta is obviously much easier than the loaded aortic arch. Professor Uchimura worked hard to speed up the stitching on his hands, while he was engrossed in maintaining the quality of the stitches with each needle.

When the last stitch was finally completed, Professor Uchimura breathed a long sigh of relief. But...... Now is not the time to be happy, only after the blood supply is restored and the heart starts beating again can Professor Uchimura's hanging heart be truly relieved.

"Start rewarming the blood, slowly perfuse and exhaust the femoral artery, stop superior vena artery reverse perfusion and cryogenic cerebral perfusion......"

"Understand, femoral artery exhaust perfusion begins to ......"

"Prepare heparin and protamine and report the patient's hematocrit at any time...... Pay attention to the bleeding from the anastomosis, Sudo assisted me in reinforcing the anastomosis!"

"Understood!"

When the surgical team member in charge of cardiopulmonary bypass released the hemostat, they saw that the blood gradually entered the patient's femoral artery through the artificial blood vessel, starting from the bypass. However, this process has to be very slow...... Because the patient has replaced the anastomosis of the aortic arch and ascending aorta at the most fragile time, if the blood flow into the patient's body is too large and the flow rate is too fast, it will cause serious damage to the patient's body, and if necessary, it will even cause the rupture of the blood vessel wall and cause serious internal bleeding.

"Report your blood sugar and make sure that your blood sugar concentration does not exceed 200......"

"Pay attention to maintaining your current blood pressure, and inject protamine and heparin ......"

……

When the process of restoring the blood supply began, Professor Uchimura continued to give instructions to the team members to ensure that the blood flow could be carried out as much as possible without affecting the patient's body.

"What about the current anal temperature?"

"The anal temperature is 23 degrees, and the blood sugar concentration is about 180......"

"The heart is exhausted, and the blood is going to flow into the heart......"

"Let go of the three branches of the aortic arch and prepare for access to the systemic circulatory ......"

"Understood!"

When Professor Uchimura's voice fell, almost everyone's eyes were focused on the heart that had stopped beating for nearly half an hour.

"Jump!"

"Jump!"

When the red blood flowed out of the newly replaced aortic arch, the stagnant heart still didn't show the slightest bit of vitality, and it seemed that things were starting to change for the worst.

"Professor?"

"Be prepared to pac and be prepared to adjust the dosage of heparin and protamine at any time......"

"Understood!"

"The first charge, start ......"

When the electrodes were placed in the patient's chest cavity and touched the heart, the heart muscle began to twitch under the weak electrical stimulation, and then Professor Uchimura quickly took out the electrodes, and then began to observe the changes in the heart.

After a moment of waiting, the originally lifeless heart finally showed signs of beating, at the beginning of which it was a gentle beat, and if you didn't pay attention, it would almost be impossible to detect, and then, the heart began to beat better and better, and the electrocardiogram, which had become a straight line, finally showed signs of starting to change.

"Ah...... The heart is beating again! it's beating again!"

"Great, Professor Uchimura, you've done it again, this operation...... It's so hard......"

"Hooray......

Seeing that the originally pale heart gradually regained its ruddy color after regaining its pulsation, Professor Uchimura's heart couldn't help but breathe a sigh of relief. In front of the operating table, the anesthesiologist who had been in charge of monitoring the anesthesia equipment was also sitting on the ground at this time, and his body had already been exhausted by this long-time operation.

"Don't be too happy just yet, now start gradually withdrawing from the cardiopulmonary bypass ......"

"Pay attention to the patient's physical signs and don't ......"

Just when Professor Uchimura wanted to explain a few more words, his physical strength made his steps stagger, and he almost fell off the operating table.

"Professor?"

"Are you alright, Professor ......"

"Professor!"

……

"Go tell Matsurenya, I'...... I want to eat tonkatsu rice after the surgery!"
