Chapter 1446

"Lao he, prepare for cardiopulmonary bypass." Zheng Ren felt it down again. Like the feeling of the system operating room, he was much more stable in his heart.

Lao he answered, turned on the timer of the mobile phone, put it at hand, and hurriedly prepared the accessories for cardiopulmonary bypass.

"Boss Zheng, where is the filter?" Liu zewei saw that Lao he began to prepare sterile pipes. At this time, he asked.

In fact, he is not curious. This is a great opportunity to cheer. It's a pity to miss it.

"About 5cm below the pulmonary valve, there may be pulmonary valve tumor, slow blood flow and thrombosis." Zheng Ren said, "Fuguier's filter is good."

The professor smiled.

Zheng Ren just casually explained that he didn't forget that this was a live operation.

First, use hemostatic pliers to separate the gap between aorta and pulmonary artery and cuff the ascending aorta.

Pull the band on the ascending aorta to the left and expose the medial side of the superior vena cava.

Then Zheng Ren stretched out his hand and said, "right angle..."

Before he finished, he clapped the right angle pliers in the palm of his hand.

Because of cardiopulmonary bypass, Zheng Ren is worried that Xie Yi people can't keep up with the operation steps.

But unexpectedly, the little Iraqi was still skilled. He looked up, bent his eyes at the little Iraqi and smiled.

Waiting for him is a pair of smiling eyes.

The four eyes are opposite. Zheng Ren forgot that it's still live.

The doctors watching the live broadcast of the operation burst in an instant!

Surgery and dog food are unbearable!

"Boss, live broadcast." Su Yun warned.

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

Just for a moment, I don't know how many doctors watching the live operation witnessed it with their own eyes.

This is the dream of many surgeons. There is a gentle and pleasant instrument nurse. They have the same heart.

Even if the operation is not as good as the operator, there is a good instrument nurse who still smiles at him!

This wave of dog food spread, and resentments all over the world rushed into the sky.

Zheng Ren didn't know what the doctors watching the live broadcast were thinking. He used right angle pliers to bypass the posterior cuff along the inner side of the superior vena cava. In the same way, wrap the inferior vena cava cuff with the inferior vena cava cuff forceps as a backup.

"Lao he, are you ready?" Zheng Ren asked.

"Well, start at any time." Old he said in a deep voice.

In this operation, he adjusted his state to the best level and wanted to show himself in front of boss Zheng.

Opportunities are rare and fleeting.

Zheng Ren didn't look up after Lao he's reply.

As soon as he reached out, the needle holder patted in the palm of his hand. At the same time, Lao he clicked the timer button.

At the distal end of the ascending aorta, two concentric purse strings were sutured with line 7.

The purse string suture technique is very delicate. The small needle only penetrates the adventitia of the blood vessels, but does not penetrate the blood vessels. The No. 7 thread is sewn around the adventitia of the aorta.

"Boss, I thought you were going to use a microscope." Su yundao.

"No, how thick the aorta is. I've been using the microscope for a long time. I'm afraid my vestibular nerve can't stand it." Zheng Rendao.

This is Zheng Ren's weakness. Taking a roller coaster will make him dizzy. Microsurgery, a slight movement, the visual field in front of you is the same as the roller coaster, and the visual field changes rapidly.

Although there is no such feeling of up and down, Zheng Ren tries to avoid too much microsurgery time.

Zhao Yunlong silently watched Zheng Ren leave a purse string on the adventitia of the aorta and remained silent.

I have done similar operations. Which time is not careful?

Although the aorta is very thick, the gap between the adventitia and the aortic trunk is ridiculously small. If you're not careful, the blood will come out.

Although not dead, hemostasis is particularly troublesome, and the operation time is extended indefinitely.

Look at boss Zheng's operation. It's as light as lifting heavy weights. The difficulty he just had is not a difficulty at all, it's just an ordinary operation.

Zhao Yunlong was still worried about Zheng Ren's level of cardiopulmonary bypass. After only one look, he understood.

Level, a geometric number level better than yourself.

Zheng renliu's purse string has one opening on the left and one on the right.

He put the purse string into the hemostatic device for hemostasis and fixation during intubation.

The adventitia of the central part of the purse was removed.

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

"I'm ready." Lao he said. He knew that boss Zheng was worried about his own hand, but this detailed instruction obviously looked down on others. Lao he muttered in his heart.

Zheng Ren smiled, then injected heparin into the right auricle, cut an incision slightly smaller than the diameter of arterial intubation in the center of the purse with a willow blade knife, withdraw the blade and send the arterial intubation into the incision of ascending aorta.

At the same time, Su Yun immediately tightened the hemostatic devices of the two purse strings and fixed the arterial intubation with the hemostatic device with thick silk thread.

Finally, the arterial intubation was fixed on the edge of the incision or the petiole of the spreader, and the intubation was connected with the artificial cardiopulmonary machine.

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

Then cut, insert the superior and inferior vena cava cannula and tighten the hemostat.

The auricle and atrial wall 2 ~ 3mm below the incision were ligated with thick silk thread around the intubation, and the upper and lower lumen intubation was fixed with this ligation line to prevent slipping off. Connect the upper and lower lumen intubation with the artificial cardiopulmonary machine.

Lao he watched the operation on the operating table while observing the time.

He has done at least hundreds of cardiopulmonary bypass. The cardiopulmonary bypass teacher can judge the operation level of the operator by following the process of establishing cardiopulmonary bypass.

3′12″……

This is a heinous time.

What was the previous record? Although he didn't finish it, Lao he was sure that boss Zheng could break the national record steadily.

Of course, this record is not officially certified.

There is a group of cardiopulmonary bypass engineers in the third class hospitals of DIDU and mordu. In the group, we record the time when the cows in their respective hospitals established cardiopulmonary bypass.

There is no harm without comparison.

They didn't hurt them anyway. If the chief surgeon has a lot to do and thinks he has a high level, he can directly take the data against others.

Lao he was proud, but he didn't smile. Instead, he glanced at the time on the timer and threw himself into his work.

I'm afraid that if others do extracorporeal circulation in the future, they can only drive honestly and kindly and talk about short stories. With this number here, who dares to play big cards?

Shame?!

Boss Zheng's hand speed is too fast and extremely stable.

If you don't pay attention, you will delay the operation process. However, Lao he was proud, that is, he, for others, had begun to delay the operation at this time.

I don't know if boss Zheng can realize his value, Lao he thought to himself.

What twin sisters, can they wear lead clothes into the operating room? Can they cooperate with cardiopulmonary bypass so skillfully?

impossible!

Zheng Ren doesn't know what Lao he is thinking. He is silently doing the operation.
