Chapter 1448 The Trouble Is Like Pregnancy (the Head Magang111 Plus More)

"Yo, boss, have you done it all?" Su Yun glanced at Shuye and said in surprise.

"Well." Zheng Ren said solemnly.

"It's so fast, why do you want ultra-low temperature?"

"I'm worried about abnormal conditions, but it's still ultra-low temperature, and I feel more at ease. After surgery, I'm in better shape, and I can do it relatively quickly." Zheng Ren said lightly while performing the operation.

In fact, in the operating room of the system, Zheng Ren couldn't be busy by himself.

So get used to the ultra-low temperature.

I had known that assistants, instrument nurses, and anesthesiologists could cooperate so well, and they wanted an ultra-low temperature of wool.

After only chatting for a while, after hearing Linger 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 resected under direct vision.

This is not a simple pulmonary valve stenosis surgery, or valve replacement surgery, as long as the pulmonary valve is removed, and then the artificial valve or the native valve is enough.

The valve was removed, and Zheng Ren cut off the tumor tissue attached to the intima of the blood vessel along the valve.

Under the naked eye, his movements are so slow that he can hardly feel his hands moving.

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

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

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

Throwing it into the pathology basin, the hemostatic forceps hit the edge of the metal basin with a crisp sound.

The main procedure of the operation is over, and the only thing left is to replace the artificial valve.

Zhao Yunlong turned his head and said to the itinerant nurse, "Wipe the sweat for me."

"Old Zhao, you didn't do anything, why are you sweating so much?"

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

"Lao Zhao, you're not good at this. You don't want to talk during the operation." Su Yun gave Zheng Ren a hand, and said contemptuously, "I'll do it later, I'll ask Fang Lin to come up, it's better than asking you. A wooden table is good."

"Fang Lin can't do it." Zhao Yunlong gave Zheng Ren a hand attentively and said, "Heart, can anyone come up and do it?"

"Boss, isn't this operation difficult?" Su Yun asked.

"It's okay." Zheng Ren began to remove the calcification.

The pulmonary valve has three leaflets, with 2mm margins left. Zheng Ren resected the valve, then removed the calcified tissue on the valve annulus, and measured the valve annulus with a prosthetic valve to determine the number of the prosthetic valve.

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

"Line." Zheng Ren stretched out his hand.

The Xie Yi people immediately slapped the newly opened suture needle, wearing a 2-0 nylon suture with a double-ended needle with a support pad, into Zheng Ren's hand.

The mattress suture was interrupted from top to bottom, and immediately after the valve annulus was sutured, it was sutured on the suture ring of the artificial heart valve. Zheng Ren was careful.

The sutures should be distributed evenly and commensurately on the suture circle of the valve annulus and the artificial heart valve, and the needle distance should be 2mm.

"Boss, your hand is too steady, not bad." Su Yun said.

"fine."

"Next time, it's enough to let Lao Zhao give you a table. This operation is too depressing." Su Yun said so, but he didn't stop at all, helping Zheng Ren to thread and press the valve.

2mm needle spacing, as if 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? It means I didn't do well in surgery." Su Yun glanced at Lao He with contempt.

"Doctor Su, when you rescued Mr. Zhao three years ago, it wasn't my anesthesia, but I watched your surgery." Lao He said seriously, "When I saw it at that time, I was shocked."

Su Yun was not complacent, and there was obviously something else to say about this.

"But the distance between the needles for anastomosis, Dr. Su doesn't seem to have reached this level as if they were measured with a ruler." Lao He said.

"Isn't it necessary at all?" Su Yun said contemptuously, "As long as it can be sewed without bleeding, it's fine. It's a matter of a few minutes, why do you make it so meticulous? You think I can't do it?"

"Hehe." Old He smiled dryly, obviously his thoughts were different.

"Prepare for implantation." Zheng Ren suddenly interrupted the two of them.

"Doing valve surgery is the most unbearable term. It's like being pregnant." Su Yun muttered.

Implantation at this time is different from the implantation of a fertilized egg.

Zheng Ren was obviously in a state of being alone, and he didn't hear what Su Yun was saying at all.

He straightened all the sutures, pushed the prosthetic valve under the annulus, and confirmed the implantation was in place.

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

Three people, each with a thread, knotted one by one.

Zheng Ren checked again for the last time and determined that the left and right coronary artery openings were unobstructed, and there was no coronary stenosis due to the problem of the thread knot.

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

"Rinse." Zheng Ren said.

A bowl 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.

"Suture."

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

Two continuous sutures of the pulmonary artery incision were made, and the last stitch was tightened for exhaust.

If there is gas left here, it is an iatrogenic air embolism.

Surgery, really is not a little detail can not be missed. Otherwise, such a small detail will lead to the death of the patient.

After the right heart and pulmonary artery were exhausted, the pulmonary artery occlusion forceps were opened.

Keep right ventricular drainage unobstructed and avoid right ventricular distention. Because it is ultra-low temperature, it is unlikely that the heart will restart on its own. Zheng Ren directly used electric shock to defibrillate and resuscitate.

The heartbeat was resuscitated, and everyone breathed a sigh of relief when they saw that the heart was beating well.

After resuscitation, the heart was left beating without load for a period of time with no problems at all.

Zheng Ren opened the superior and inferior vena cava occlusion bands and entered parallel circulation. After the auxiliary circulation for a period of time, the shutdown conditions are met, and the Laohe side will shutdown in time.

"Come on." Zheng Ren turned around and stepped down.

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

"I'm not in a hurry to look at the pulmonary valve tumor." Zheng Ren came out of the sage state of concentration at this time, smiled, and said, "Pulmonary valve tumor, have you seen it?"

"No." Su Yun and Zhao Yunlong began to find the bleeding point, sutured the pericardium, left drainage strips, and closed his chest.

The operation went smoothly, and after the patient's heartbeat was resuscitated, the oxygen saturation in the blood directly reached 100% under the condition of pure oxygen inhalation.

It's alright, Lao He directly judged. Hu Yanhui stopped the live broadcast and came in to take off the live broadcast glasses for Zheng Ren.

Zheng Ren came to the pathology basin and carefully examined the cut tumor.

Lao He leaned over to Zheng Ren and asked with a smile, "Boss Zheng, I thought you wanted ultra-low temperature, and the operation will take at least 4 hours."

"It's not that you cooperated well. The cardiopulmonary bypass went smoothly and unexpectedly." Zheng Ren held the lancet in his hand and dissected the tumor tissue in the pathology basin.

Happy old man.
