“Yo, boss, we’ve done this much?” Su Yun glanced at the surgical field and said in surprise.

“Yes.” Zheng Ren said in a deep voice.

“Why do you need ultra – Low temperatures when you’re doing it so quickly?”

“I’m worried that there’s something abnormal. It’s better to keep the temperature low. When you’re in the right condition and have a better grasp of the surgery, you can perform it relatively faster. ” Zheng Ren said indifferently as he performed the surgery.

In fact, Zheng Ren could not handle everything by himself in the system operating theater.

That was why he had to get used to the ultra – Low temperature.

If he had known that the assistant, scrub nurse, and anesthetist would cooperate so well, he would not have asked for ultra – Low temperature.

After chatting for a while and listening to Lin GE’s gossip, Zheng Ren had already separated the blood vessel membrane and reached the position of the pulmonary artery valve.

He cut open the membrane and removed the pulmonary artery valve under his gaze.

This was not a simple surgery for pulmonary valve blockage or a valve replacement surgery. All they had to do was remove the autologous valve and change the artificial or pulmonary valve.

After removing the valve, Zheng Ren removed the tumor tissue attached to the inner membrane of the blood vessel.

Under the naked eye, his movements were very slow, and it was almost impossible to feel his hands moving.

Su Yun did not say anything. She quietly watched Zheng Ren’s surgery and started to help open the pulmonary artery to remove the tumor tissue.

Even though he managed to get to this step very quickly, it took him nearly 30 minutes to remove the tumor tissue.

Finally, the tumor tissue was cut off together with the hemostatic forceps.

He threw it into the pathology bowl, and the hemostatic forceps hit the edge of the metal bowl, making a crisp sound.

The main part of the surgery was over, and all that was left was to change the artificial valve.

Zhao Yunlong turned his head and said to the circulating nurse,””Help me wipe my sweat.”

“Old Zhao, you didn’t even do anything. Why are you sweating so much?”

Zhao Yunlong did not say anything. He continued with the surgery with a serious expression.

“Old Zhao, this is the only bad thing about you. You don’t like to talk during surgery.” Su Yun held Zheng Ren’s hand and said in disdain,””I’ll do it in the future. It’s better for me to call Fang Lin up than a blockhead like you to pair up the stage.”

“Fang Lin can’t do it.” Zhao Yunlong put his hand on Zheng Ren’s and said,””Magnanimity, can anyone do that?”

“Boss, is the surgery not difficult?” Su Yun asked.

“It’s alright. ” Zheng Ren began to clear the calcium in the area.

The pulmonary artery valve had three segments, and the edge was 2mm wide. Zheng Ren removed the valve and removed the calcified tissue on the ring. He then measured the ring with a valve tester to determine the number of the artificial valve.

Zhao Yunlong had brought all kinds of valves here. Zheng Ren picked one, and the circulating nurse opened it. Xie Yiren handed it over.

“Thread.” Zheng Ren reached out his hand.

Xie Yiren then placed the newly opened sewing needle, which was wearing a 2 – X -0 nylon thread with a double – headed needle, into Zheng Ren’s hand.

Zheng Ren performed a mattress suture from top to bottom. After suturing the valve ring, he immediately sutured the loop around the artificial heart valve. He was very careful.

The suture should be evenly distributed on the suture ring of the artificial heart valve and the artificial heart valve, and the needle should be 2mm apart.

“Boss, your hand is too steady. Not bad.” Su Yun said.

“It’s alright. ”

“Next time, I’ll just ask old Zhao to set up a table for you. This surgery is too depressing.” Even though Su Yun said that, her hands did not stop as she helped Zheng Ren with the thread and the valve.

The two – mm needle gap seemed to have been measured with a ruler.

“Boss Zheng, your skill level is really high.” Old he looked at it and said emotionally.

“What’s the matter, old he? It means that I didn’t perform the surgery well. ” Su Yun looked at old he in disdain.

“Doctor su, three years ago, when you saved President Zhao’s operating theater, I wasn’t the one who administered anesthesia, but I watched your surgery.” Old he said very seriously,”when I saw it, I was shocked.”

Su Yun wasn’t smug. There was obviously more to her words.

“But doctor su, you don’t seem to have reached the level where you can measure the distance between the anastomosed needles with a ruler.” Old he said.

“There’s no need for that. ” Su Yun said disdainfully,”as long as it can be stitched up and there’s no bleeding, it’s fine. It’s just a matter of a few seconds. Why did you have to make it so thin?” You think I can’t do it?”

“Hehe.” Old he smiled dryly. Obviously, he had a different thought.

“Get ready to get into bed.” Zheng Ren suddenly interrupted the two.

“When it comes to valve surgery, I can’t stand this kind of jargon. It’s as if you’re pregnant.” Su Yun mumbled.

The current implantation was different from the embryo implantation.

Zheng Ren was obviously in a state of nonchalance and did not hear what Su Yun was saying.

He straightened all the stitches, pushed the artificial flap under the ring, and confirmed that the bed was in place.

Zheng Ren was only relieved after repeatedly confirming that the artificial valve was not blocking the opening of the left and right coronary arteries.

The three of them each took a thread and tied a knot.

Zheng Ren did a final check to make sure that the opening of the left and right coronary arteries was clear and that there was no coronary artery narrowing due to the knot.

He had to be careful here. Otherwise, after the surgery, the patient would immediately show symptoms of myocardial infarction.

“Rinse it.” Zheng Ren said.

The basin of iced salt water was handed over.

Zheng Ren thoroughly rinsed the aorta and left chamber below the artificial valve and filled the aorta and left chamber with saline solution.

“Suture.”

The needle – holder with the 5 – inch surgical thread was placed in Zheng Ren’s hand.

He continuously sutured two incisions on the pulmonary artery, tightened the last needle, and pumped gas out.

If there was gas left here, it would be a medical source of air embolism.

Not a single detail could be missed in a surgery. Otherwise, such a small detail would have caused the patient’s death.

After the right heart and pulmonary artery had pumped gas, he opened the pulmonary arcanotacle.

Keep the right heart drainage smooth and prevent the right heart from swelling. As it was at an extremely low temperature, the possibility of the heart beating on its own was not high. Zheng Ren directly used an electric shock to resuscitate the patient.

Everyone heaved a sigh of relief when they saw that the heart was beating well.

After resuscitation, the heart would be beating without any burden for a period of time without any problems.

Zheng Ren opened the superior and inferior vena cava and entered parallel circulation. After the auxiliary circulation went on for a while, it met the conditions for shutdown, and old he’s side shut down in time.

“You guys do it.” Zheng Ren turned around and left the stage.

“Boss, your Typhoon is getting worse.” Su Yun nagged.

“I’m just in a hurry to get a look at the pulmonary valve tumor. ” Zheng Ren came out of his focused Sage state at this time, smiled, and said,””Have you seen a pulmonary valve tumor before?”

“No, I didn ‘t,” Su Yun and Zhao Yunlong started to find the bleeding point. They then sutured the pericardium, left the drainage strip, and closed the chest.

The operation was successful. After the patient’s heart was resuscitated, the blood oxygen saturation level reached 100% when he inhaled pure oxygen.

‘Everything’s fine now,’ old he concluded. Hu Yanhui stopped the live broadcast and came in to help Zheng Ren take off his live broadcast glasses.

Zheng Ren came to the pathological basin and carefully examined the tumor that had been removed.

Old he went to Zheng Ren’s side and asked with a smile,””Boss Zheng, I thought you wanted the surgery to be done at an ultra – Low temperature, so the surgery would take at least four hours.”

“It’s all because of your good cooperation. The cardiopulmonary bypass is carried out smoothly, unexpectedly smoothly. ” Zheng Ren was dissecting the tumor in the pathology basin with a lancets in his hand.

Old he was proud.
