"Yo, Boss, you're already here?" Su Yun glanced at the operative view and said in surprise.
"Yes," Zheng Ren said in a deep voice.
"Why do you need ultra-low temperature to do it so quickly?"
"I'm worried about abnormal conditions. It's better to use ultra-low temperature to feel more at ease. Surgery, when the condition is good, it's relatively faster, "Zheng Ren said faintly as he performed the surgery.
In fact, Zheng Ren could not handle everything alone in the System's operating theater.
Therefore, he had to get used to the ultra-low temperature.
If he had known that the assistant, scrub nurse, and anesthesiologist could cooperate so well, he would not have needed ultra-low temperature.
After chatting for a while and listening to Lin Ge's gossip, Zheng Ren had already separated the intima of the blood vessel and reached the position of the pulmonary valve.
He cut open the intima and removed the pulmonary valve under direct vision.
This was not a simple pulmonary valve stenosis surgery or valve replacement surgery. He only needed to remove the pulmonary valve and then replace it with an artificial or autologous valve.
After removing the valve, Zheng Ren cut off the tumor tissue attached to the intima of the blood vessel along with the valve.
Under direct vision, his movements were very slow, and his hands could hardly be felt.
Su Yun did not say anything and quietly watched Zheng Ren's surgery. He began to help open the pulmonary artery and help remove the tumor tissue.
Although this step was done quickly, it took nearly 30 minutes to remove the tumor tissue.
Finally, with hemostatic forceps, the tumor tissue was cut off.
It was thrown into the pathology basin. The hemostatic forceps hit the edge of the metal basin, making a crisp sound.
The main process of the surgery was over. All that was left was to replace the artificial valve.
Zhao Yunlong turned his head and said to the circulating nurse, "Help me wipe my sweat."
"Old Zhao, you haven't done anything yet. Why are you sweating so much?"
Zhao Yunlong did not say anything and continued the surgery with a serious expression.
"Old Zhao, this is your bad point. You don't want to talk during the surgery," Su Yun said disdainfully as he helped Zheng Ren. "I'll do it next time. I'll ask Fang Lin to come up. It's better than finding a blockhead like you."
"Fang Lin can't do it." Zhao Yunlong focused on helping Zheng Ren and said, "Is broad-mindedness something that anyone can do?"
"Boss, this surgery is not difficult, right?" Su Yun asked.
"It's alright." Zheng Ren began to remove the calcification.
The pulmonary valve had three lobes with a margin of 2mm. Zheng Ren removed the valve and removed the calcified tissue on the annulus. He then measured the annulus with a valvetometer to determine the number of the prosthetic valve.
Zhao Yunlong came up with all kinds of valves. Zheng Ren picked one and the circulating nurse opened it. Xie Yiren handed it over.
"Thread." Zheng Ren stretched out his hand.
Xie Yiren placed the newly opened suture needle in his hand. It was a 2-0 nylon suture with a support pad.
He performed an interrupted mattress suture from top to bottom. After suturing the annulus, he immediately sutured it onto the suture ring of the artificial heart valve.
The suture line should be evenly distributed and proportionate on the suture circle of the annulus and the artificial heart valve. The stitch distance should be 2mm.
"Boss, your hand is too steady. Not bad." Su Yun said.
"It's alright."
"Next time, just ask Old Zhao to set up the operating table for you. This surgery is too depressing." Although Su Yun said that, his hands did not stop at all. He helped Zheng Ren threading the thread and pressing the valve.
The 2mm distance between the needles seemed to have been measured with a ruler.
"Boss Zheng, your standard is really high," Lao He said with emotion as he looked at it.
"What's wrong, Lao He? Do you mean that I didn't do the surgery well? "Su Yun looked at Lao He disdainfully.
"Doctor Su, when you gave Chief Zhao the operating table three years ago, I wasn't the one who anesthetized him, but I watched your surgery," Lao He said very seriously. "At that time, I saw it. It was shocking."
Su Yun was not proud. There was obviously more to what he said.
"But Doctor Su doesn't seem to have reached the distance between the needles for the anastomosis. It's as if he used a ruler to measure it," Lao He said.
"There's no need at all," Su Yun said disdainfully. "As long as it can be sutured and doesn't bleed, it's fine. It's just a matter of a few meters. Why do you have to be so detailed? Do you think I can't do it? "
"Hehe." Lao He smiled dryly. It was obvious that his thoughts were different.
"Prepare the bed." Zheng Ren suddenly interrupted the two of them.
"I can't stand this kind of thing the most when it comes to valve surgery. It's as if I'm going to be pregnant," Su Yun muttered.
The implantation at this time was different from the implantation of a fertilized egg.
Zheng Ren was obviously in a state where no one was around. He did not hear what Su Yun was saying at all.
He straightened all the sutures and pushed the artificial valve under the ring to confirm that it was in place.
After repeatedly confirming that the artificial valve did not block the left and right coronary artery openings, Zheng Ren was relieved.
The three of them each had a thread and knotted it one by one.
Zheng Ren checked again and confirmed that the left and right coronary artery openings were unobstructed. There was no coronary artery stenosis because of the problem with the thread knots.
He had to be careful here. Otherwise, after the surgery was completed, the patient would immediately have symptoms of myocardial infarction.
"Rinse," Zheng Ren said.
The basin of ice saline was handed over.
Zheng Ren thoroughly rinsed the aorta and left ventricle above and below the artificial valve and filled the aorta and left ventricle with normal saline.
"Suture."
The needle holder with the 5-0 suture was slapped into Zheng Ren's hand.
He continuously sutured the pulmonary artery incision twice. The last needle was tightened and the exhaust was carried out.
If there was gas left here, it would be considered an iatrogenic air embolism.
During the surgery, not a single detail could be missed. Otherwise, such a small detail could cause the patient's death.
After the right heart and pulmonary artery were vented, the pulmonary artery occlusion forceps were opened.
Keep the right heart drainage smooth and avoid the right heart from expanding. Because it was extremely low temperature, the possibility of the heart beating on its own was not high. Zheng Ren directly used electric shock to resuscitate it.
After the heartbeat was recovered, everyone heaved a sigh of relief when they saw that the heart was beating well.
After the resuscitation, the heart was beating without any load for a period of time. There was no problem at all.
Zheng Ren opened the superior and inferior vena cava occlusion and entered the parallel circulation. After the auxiliary circulation for a period of time, the conditions for stopping were met. Lao He stopped in time.
"You guys can do it." Zheng Ren turned around and left the stage.
"Boss, your attitude is getting worse and worse," Su Yun nagged.
"I'm just anxious to see the pulmonary valve tumor." At this time, Zheng Ren came out of his dedicated sage state. He smiled and said, "Have you seen a pulmonary valve tumor before?"
"No." Su Yun and Zhao Yunlong began to look for the bleeding point. They sutured the pericardium, left a drainage strip, and closed the chest.
The surgery went smoothly. After the patient's heart was resuscitated, the blood oxygen saturation directly reached 100% under the condition of pure oxygen.
'It's okay,' Lao He immediately judged.
He went to Zheng Ren's side and asked with a smile, "Boss Zheng, I thought you wanted to use ultra-low temperatures. The surgery would take at least four hours."
"It's all because of your good cooperation. The extracorporeal circulation went smoothly. It was unexpectedly smooth." Zheng Ren held a lancet in his hand and dissected the tumor tissue in the pathological basin.
Lao He was proud.
