Chapter 1449

"Yo, boss, have you done it here?" Su Yun glanced at the art field and said in surprise.

"Yes." Zheng Ren said in a deep voice.

"It's done so fast. Why do you want ultra-low temperature?"

"Worry about abnormal conditions, or ultra-low temperature, I'm more secure. When the operation comes up and goes smoothly, I can do it relatively quickly." Zheng Ren said faintly while doing the operation.

In fact, Zheng Ren can't be busy alone in the system operating room.

So get used to ultra-low temperature.

I knew that assistants, equipment nurses and anesthesiologists could cooperate so well. I wanted an ultra-low temperature of wool.

After chatting for a while and listening to linge's gossip, Zheng Ren had dissociated the intima of the blood vessel and reached the position of the pulmonary valve.

The intima was cut and the pulmonary valve was removed under direct vision.

This is not a simple operation for pulmonary stenosis or valve replacement. It is enough to remove the pulmonary valve and replace the artificial valve or autologous valve.

After removing the valve, Zheng Ren cut off the tumor tissue attached to the intima along the valve.

With the naked eye, his movements were so slow that he could hardly feel his hands moving.

Su Yun stopped talking and quietly watched Zheng Ren's operation. He began to help open the pulmonary artery and take out the tumor tissue.

Although this step was done quickly, it took nearly 30 minutes to take the tumor tissue.

Finally, with hemostatic forceps, the tumor tissue was cut down.

Throw it into the pathological basin, and the hemostatic forceps hit the edge of the metal basin, making a crisp sound.

The main procedure of the operation has been completed, and the rest is to replace the artificial valve.

Zhao Yunlong turned his head and said to the itinerant nurse, "help me wipe my sweat."

"Lao Zhao, you didn't do it. Why are you sweating so much?"

Zhao Yunlong didn't speak and continued the operation with a serious face.

"Lao Zhao, that's not good for you. You don't want to talk during the operation." While giving Zheng Ren a hand, Su Yun said contemptuously, "I'll do it later. I'll ask Fang Lin to come up. It's better than looking for a wooden platform like you."

"Fang Lin can't do it." Zhao Yunlong wholeheartedly gave Zheng Ren a hand and said, "mind, can everyone come up and do it?"

"Boss, is this operation not difficult?" Su Yun asked.

"OK." Zheng Ren began to remove calcification.

The pulmonary valve has three lobes, with 2mm left at the edge. Zheng Ren removed the valve, then removed the calcified tissue on the valve ring, and measured the valve ring with a valve tester to determine the number of artificial valve.

Zhao Yunlong came up with various valves. Zheng Ren chose the same. The itinerant nurse opened it and Xie Yi handed it over.

"Line." Zheng Ren stretched out his hand.

Xie Yi immediately patted the newly opened suture needle wearing 2-0 nylon suture with double headed needle with support pad in Zheng Ren's hand.

The mattress suture was interrupted from top to bottom. After sewing the valve ring, it was immediately sewn on the suture ring of the artificial heart valve. Zheng Ren was careful.

The suture shall be evenly and proportionally distributed on the suture ring of valve ring and artificial heart valve, and the needle pitch shall be 2mm.

"Boss, your hand is too steady. It's good." Su yundao.

"OK."

"It's enough to let Lao Zhao match the table for you next time. The operation is too depressing." Su Yun said so, but he didn't stop at all. He helped Zheng Ren thread and press the valve.

2mm needle spacing, as 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? I mean, I didn't do a good operation." Su Yun looked at Lao he with disdain.

"Dr. Su, the time you rescued president Zhao three years ago was not my anesthesia, but I saw your operation." Lao he said seriously, "it was amazing to see it at that time."

Su Yun was not proud. There was obviously something to be said later.

"But Dr. Su doesn't seem to have reached the matching needle spacing. It's like measuring it with a ruler." Lao he said.

"It's not necessary at all." Su Yun said contemptuously, "as long as you can sew it and don't bleed, why are you so thin for a few humi things? Do you think I can't do it?"

"Hey, hey." Old he smiled dryly. It was obvious that his ideas were different.

"Get ready for implantation." Zheng Ren suddenly interrupted their conversation.

"I can't stand this term when I do valve surgery. It's like I'm going to be pregnant." Su Yun muttered.

Implantation at this time is different from that of fertilized egg.

Zheng Ren was obviously in a state of no one else. He didn't hear what Su Yun was saying at all.

He straightened all the sutures, pushed the artificial valve under the valve ring and confirmed that the implantation was in place.

After repeatedly confirming that the artificial valve did not block the openings of the left and right coronary arteries, Zheng Rencai was relieved.

One thread for each of the three and tie the knot one by one.

Zheng Ren finally checked again and confirmed that the openings of the left and right coronary arteries were unobstructed, and there was no coronary stenosis due to the problem of suture knot.

We must be careful here, or the patient will have the symptoms of myocardial infarction immediately after the operation is completed.

"Flush." Zheng Rendao.

The ice salt water basin 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.

"Stitch."

The needle holder holding 5-0 suture was patted in Zheng Ren's hand.

The pulmonary artery incision was sutured continuously for two times, and the last needle was tightened for exhaust.

If gas is left here, it belongs to iatrogenic air embolism.

Surgery, really, no details can be omitted. Otherwise, such a small detail will lead to the death of the patient.

After venting the right heart and pulmonary artery, open the pulmonary artery blocking forceps.

Keep the right heart drainage unobstructed to avoid right heart expansion. Because it is ultra-low temperature, it is unlikely that the heart will rebound by itself. Zheng Ren directly used electric shock to defibrillate and resuscitate.

Everyone was relieved to see that the heart beat well.

After resuscitation, make the heart beat without load for a period of time, without any problem at all.

Zheng Ren opened the superior and inferior vena cava blocking zone and entered the parallel circulation. After a period of auxiliary circulation, it meets the shutdown conditions, and Lao he's side stops in time.

"Come on." Zheng Ren turned to step down.

"Boss, your typhoon is getting worse and worse." Su Yun nagged.

"I'm in a hurry to see the pulmonary valve tumor." At this time, Zheng Ren came out of the state of dedicated sage, smiled and said, "have you seen pulmonary valve tumor?"

"No." Su Yun and Zhao Yunlong began to find the bleeding point, suture the pericardium, leave a drainage strip and close the chest.

The operation was successful. After the patient's heartbeat was resuscitated, the blood oxygen saturation directly reached 100% under the condition of pure oxygen.

It's all right, Lao he directly judged. Hu Yanhui stopped the live broadcast and came in to take off Zheng Ren's live broadcast glasses.

Zheng Renlai went to the pathological basin and looked carefully at the cut tumor.

Lao he came to Zheng Ren and asked with a smile, "boss Zheng, I thought you wanted ultra-low temperature. The operation should take at least 4 hours."

"You didn't cooperate well. The cardiopulmonary bypass was smooth and unexpectedly smooth." Zheng Ren, holding a lancet in his hand, dissected the tumor tissue in the pathological basin.

Lao he is proud.
