Chapter 1446： It’s too ethical to have surgery and sprinkle dog food.

"Old congratulations, prepare for extracorporeal circulation." Zheng Ren touched down again, and felt the same as the system operating room, and his heart was much more stable.

Lao He should have a voice, open the timer of the mobile phone, put it at hand, and rush to prepare the accessories for extracorporeal circulation.

"Zheng boss, where is the filter?" Liu Zewei saw Laohe begin to prepare sterile pipes, and asked about this time.

In fact, he is not curious. This is a great opportunity to hold a hand. It is a pity to miss it.

"About 5cm below the pulmonary valve, there may be a pulmonary artery tumor, the blood flow slows down, and there is a thrombus." Zheng Rendao: "The rich under the filter is good."

The professor smiled aside.

Zheng Ren just explained it casually. He did not forget that this was a live surgery.

The hemostatic forceps are used to separate the gap between the aorta and the pulmonary artery, and the ascending aorta is sheathed.

Pull the band on the ascending aorta to the left to reveal the inside of the superior vena cava.

Then Zheng Renyi reached out and said: "Right angle..."

The words were not finished, right angle pliers were shot in the palm of your hand.

Because of the extracorporeal circulation, Zheng Ren worried that the Xie Yi people could not keep up with the steps.

But I didn't expect the Xiaoyi people to still be proficient. He looked up and bent at the Xiaoyi people and smiled.

Waiting for him is a pair of smiles.

Four eyes are opposite, Zheng Ren forgets that it is still live.

The doctors who watched the live broadcast of the operation exploded in an instant!

Surgery, dog food, it is simply unbearable!

"Boss, live broadcast." Su Yun reminded.

"..." Zheng Ren bowed his head and looked at the operation area again.

Just a moment, I don’t know how many doctors who watched the live broadcast of the operation witnessed it.

This is how many surgeons dream, there is a gentle and instrumental nurse, the two are connected.

The surgery is not as good as the surgery, and there is a good equipment nurse, and even laugh at him!

This wave of dog food sprinkled, the resentment around the world went straight into the sky.

Zheng Ren did not know what the doctors watching the live broadcast thought. He used right angle pliers to bypass the back of the superior vena cava. In the same way, the inferior vena cava strap is clamped with a lower lumen strap as a backup.

"Old congratulation, are you ready?" Zheng Ren asked.

"Okay, start at any time."

In this operation, he adjusted his state to the best level and showed himself in front of Zheng Bo.

The opportunity is rare and fleeting.

After receiving the reply from Laohe, Zheng Ren did not look up.

As soon as he reached out, the needle holder was shot in the palm of his hand. At the same time, Laohe ordered the button of the timer.

At the distal end of the ascending aorta, use the 7th line for two concentric purse sutures.

The method of suturing the purse is extremely delicate. The small needle only penetrates the outer membrane of the blood vessel, but does not penetrate the blood vessel. The suture 7 is sewn around the outer membrane of the aorta.

"Boss, I thought you would use a microscope." Su Yundao.

"No, the aorta is thick, and it takes a long time with the microscope. I am worried that my vestibular nerve can't stand it." Zheng Rendao.

This is the weakness of Zheng Ren, who will be dizzy when riding a roller coaster. Microsurgery, a slight movement, the vision in front of the eye and the roller coaster, the visual field changes rapidly.

Although there is no such feeling of ignorance, Zheng Ren tries to avoid excessive microsurgery time.

Zhao Yunlong silently watched Zheng Ren leave the purse line in the adventitia of the aorta and silenced.

I have done a similar operation myself. Which time is it not careful?

Although the aorta is very thick, the gap between the adventitia and the aorta is small. A little careless, the blood will spray out.

Although it is not dead, it is particularly troublesome to stop bleeding, and the operation time is extended indefinitely.

Looking at the operation of Zheng Boss, if the weight is light, the difficulty is just not difficult under his hand, just ordinary operation.

Zhao Yunlong was still worried about Zheng Ren’s level of extracorporeal circulation surgery. He only took a look and understood it.

Level, a geometric level stronger than yourself.

Zheng Renliu’s purse line is open to the left and right.

He put the purse string into the hemostat and prepared to stop bleeding and fix it during intubation.

The outer membrane of the central portion of the purse is removed.

"Heparin, 3mg/kg." Zheng Rendao.

"Get ready early." Old congratulations. He knows that Zheng boss is worried about his own hands, but this detailed embarrassment, obviously some people look down on it, and the old greetings muttered.

Zheng Ren smiled, then injected heparin into the right atrial appendage, and then cut a small incision smaller than the diameter of the arterial cannula in the center of the purse with a lancet blade, and the arterial cannula was sent into the ascending aorta incision while exiting the blade.

At the same time, Su Yun immediately tightened the hemostats of the two purse lines and fixed the arterial cannula with the hemostatic device with a thick thread.

Finally, the arterial cannula is fixed on the edge of the incision or the petiole of the distractor, and the cannula is connected to the artificial heart-lung machine.

Similar to this step, Zheng Ren then sewed a purse string in the right atrial appendage and the right atrium, and put on a hemostat.

The incision is then inserted into the superior and inferior vena cava cannula to tighten the hemostat.

A 2 to 3 mm atrial appendage and atrial wall below the incision were ligated around the cannula with a thick wire, and the upper and lower lumen cannula was fixed by the ligature to prevent slipping. Connect the upper and lower lumen cannula to the artificial heart-lung machine.

Lao He looked at the operation while watching the operation on the operating table.

He has had extracorporeal circulation for at least a few hundred cases. From the process of establishing extracorporeal circulation, the cardiopulmonary can determine the surgeon's level of surgery.

3'12"...

This is a heinous time.

What is the record of the past? Although not finished, Lao He confirmed that Zheng’s boss can break the national record.

Of course, this record is not officially certified.

The extracorporeal circulators of the large-scale top three hospitals in the Imperial Capital and the Magic City have a group. In the group, everyone recorded the time for the extracorporeal circulation in the hospitals.

There is damage in comparison.

Anyway, it is not their injury. If the surgeon has a lot of things, I still think that my level is high can directly take the data.

Lao He was proud of his heart, but he did not laugh, but took a glance at the time on the timer and put it into work.

I am afraid that if others do extracorporeal circulation in the future, they can only drive honestly and with enthusiasm, and talk about small pieces. With this number here, who dares to play big names?

Still shameless? !

Mr. Zheng’s hand is too fast and extremely stable.

If you don't pay attention to it, you will delay the surgery. However, Lao He’s heart is proud, that is, he is, for others, this time has begun to delay surgery.

I don't know if Zheng boss can realize his own value.

What twin sisters spend, can they wear lead clothes into the operating room? Can they be so skilled in the coordination of extracorporeal circulation?

impossible!

Zheng Ren did not know what Lao He was thinking. He was doing surgery in silence.
