"Hey, boss, are you all here?" Su Yun glanced at Shu Ye and said in surprise.
"Yeah." Zheng Ren said solemnly.
"It's done so fast, why do you need ultra-low temperature?"
"I'm worried about something abnormal. It's still ultra-low temperature, so I feel more at ease. As for the surgery, I'm in good condition and it's smooth, so I can do it relatively quickly." Zheng Ren said calmly while performing the surgery.
In fact, Zheng Ren is too busy alone in the system operating room.
So you have to get used to ultra-low temperatures.
If I had known that the assistant, equipment nurse, and anesthesiologist could cooperate so well, I would have needed a woolen ultra-low temperature.
After only chatting for a while and listening to Lin Ge's gossip, Zheng Ren had already freed the intima of the blood vessel and reached the position of the pulmonary valve.
The intima was incised and the pulmonary valve was removed under direct vision.
This is not a simple pulmonary valve stenosis surgery or valve replacement surgery. It is enough to remove the pulmonary valve and then replace it with an artificial valve or a native valve.
After removing the valve, Zheng Ren cut off the tumor tissue attached to the intima of the blood vessel along the valve.
To the naked eye, his movements were very slow, and you could barely feel his hands moving.
Su Yun stopped talking and quietly watched Zheng Ren's operation, and began to help open the pulmonary artery and remove the tumor tissue.
Although this step was accomplished very quickly, it only took nearly 30 minutes to remove the tumor tissue.
Finally, with the hemostatic forceps, the tumor tissue was cut out.
Throwing it into the pathology basin, the hemostatic forceps hit the edge of the metal basin and made a crisp sound.
The main part of the surgery is over, and all that's left is to replace the artificial valve.
Zhao Yunlong turned his head and said to the traveling nurse: "Wipe my sweat for me."
"Old Zhao, you didn't do anything, why are you sweating so much?"
Zhao Yunlong said nothing and continued the operation with a serious face.
"Old Zhao, that's the only bad thing about you. You don't want to talk during the operation." Su Yun gave Zheng Ren a hand and said disdainfully: "If we do it again in the future, I'll ask Fang Lin to come up. It's better than asking you to do this." A wooden table goes well.”
"Fang Lin can't do it." Zhao Yunlong concentrated on helping Zheng Ren and said, "With a big heart, can anyone do it?"
"Boss, is this surgery not difficult?" Su Yun asked.
"It's okay." Zheng Ren began to remove the calcifications.
The pulmonary valve has three leaflets, with a margin of 2 mm. Zheng Ren removed the valve, then removed the calcified tissue on the valve annulus, and used a valve measuring device to measure the valve annulus to determine the number of the artificial valve.
Zhao Yunlong came up with various valves, Zheng Ren chose one, the circulating nurse opened it, and Xie Yiren handed it over.
"Thread." Zheng Ren stretched out his hand.
Xie Yiren immediately patted the newly opened suture needle, which was wearing a 2-0 nylon suture with a double-ended needle with a support pad, into Zheng Ren's hand.
Zheng Ren was careful with the interrupted mattress sutures from top to bottom. After sewing through the valve annulus, it was immediately sewn onto the suture circle of the artificial heart valve.
The sutures should be evenly distributed and proportional on the suture circles of the valve annulus and the artificial heart valve, with a needle pitch of 2mm.
"Boss, your hands are too steady, not bad." Su Yun said.
"fine."
"Next time, just let Lao Zhao set up a table for you. This surgery is too depressing." Su Yun said this, but his hands did not stop at all, helping Zheng Ren thread the thread and press the valve.
The 2mm pin spacing looks like it was measured with a ruler.
"Boss Zheng, your level is really high." Lao He looked at it and said with emotion.
"What's the matter, Lao He? You mean my surgery was not good." Su Yun glanced at Lao He with disdain.
"Dr. Su, when you rescued Mr. Zhao three years ago, I wasn't anesthetized, but I watched your operation." Lao He said seriously, "I was shocked when I saw it at that time."
Su Yun was not proud, there was obviously something behind his words.
"But the distance between the needles for the anastomosis does not seem to be as good as measured with a ruler by Dr. Su." Lao He said.
"It's completely unnecessary." Su Yun said scornfully: "As long as it can be sewn without bleeding, why do you need to do it so finely for just a few square meters? Do you think I can't do it?"
"Hehe." Lao He smiled dryly. It was obvious that he had different ideas.
"Get ready for bed." Zheng Ren suddenly interrupted the two of them.
"I can't stand this kind of thing when I undergo valve surgery. I feel like I'm pregnant." Su Yun muttered.
Implantation at this time is different from implantation of a fertilized egg.
Zheng Ren was obviously in a state of indifference and didn't hear what Su Yun was saying.
He straightened all the sutures, pushed the artificial valve under the annulus, and confirmed that the implantation was in place.
Zheng Ren felt relieved after repeatedly confirming that the artificial valve did not block the openings of the left and right coronary arteries.
Three people each have one thread and tie the knots one by one.
Zheng Ren checked again for the last time and confirmed that the openings of the left and right coronary arteries were unobstructed, and there was no coronary artery stenosis due to knotting problems.
You must be careful here, otherwise the patient will have symptoms of myocardial infarction immediately after the operation is completed.
"Rinse." Zheng Ren said.
The basin of ice salt water was handed over.
Zheng Ren thoroughly flushed the aorta and left ventricle above and below the artificial valve, and filled the aorta and left ventricle with normal saline.
"Sew."
The needle holder holding the 5-0 suture was slapped into Zheng Ren's hand.
Two consecutive pulmonary artery incisions are sutured, and the last stitch is tightened for exhaust.
If air remains here, it is an iatrogenic air embolism.
During surgery, no detail can be missed. Otherwise, just such a small detail could lead to the death of the patient.
After the right heart and pulmonary artery are exhausted, open the pulmonary artery clamp.
Keep right heart drainage smooth and avoid right heart expansion. Because of the ultra-low temperature, it is unlikely that the heart will restart on its own. Zheng Ren directly used electric shock to defibrillate and revive him.
The heartbeat was revived and everyone was relieved to see that the heart was beating well.
After resuscitation, the heart is allowed to beat without load for a period of time without any problems at all.
Zheng Ren opened the superior and inferior vena cava blocking bands and entered parallel circulation. After auxiliary circulation for a period of time, the shutdown conditions are met, and Lao He's side shuts down in time.
"Come on." Zheng Ren turned around and stepped off the stage.
"Boss, your typhoon is getting worse and worse." Su Yun nagged.
"I'm anxious to see the pulmonary valve tumor." Zheng Ren came out of his concentrated sage state at this time, smiled and said, "Have you seen the pulmonary valve tumor?"
"No." Su Yun and Zhao Yunlong began to search for the bleeding point, sutured the pericardium, left a drainage strip, and closed the chest.
The operation went smoothly. After the patient's heartbeat was resuscitated, his blood oxygen saturation reached 100% while breathing pure oxygen.
It's okay, Lao He judged directly.
He approached Zheng Ren and asked with a smile: "Boss Zheng, I thought you would need ultra-low temperature and the operation would take at least four hours."
"It's not because you cooperated well. The extracorporeal circulation went smoothly, surprisingly smoothly." Zheng Ren held a lancet in his hand and dissected the tumor tissue in the pathology basin.
Lao He was proud.
