Chapter 1493: with translation of chapter title

1446 do Shou Bing, sprinkle dog food, too immoral.

「Lao He, prepare extracorporeal circulation. 」 Zheng Ren again felt down, same as the feeling in the System Operating Room, heart became much more stable.

Lao He responded, opened the phone's timer, placed it at hand, hurriedly preparing the accessories for extracorporeal circulation.

「Zheng Lao Ban, where is the filter's position? 」 Liu Zewei saw Lao He start preparing sterile tubing, took the opportunity to ask.

Actually he wasn't curious; this was a perfect chance to play the straight man, missing it would really be a pity.

「About 10cm below the pulmonary artery valve, possibly due to a pulmonary artery valve tumor causing slowed blood flow and thrombosis. 」 Zheng Ren said: 「The filter below Fugui'er is not bad. 」.

The professor chuckled to himself on the side.

Zheng Ren just casually explained a sentence; he hadn't forgotten, this was a live broadcast surgery.

First use Hemostatic Forceps to separate the gap between the aorta and pulmonary artery, to put a band on the ascending aorta.

Pull the band on the ascending aorta leftward, revealing the inner side of the superior vena cava.

Then Zheng Renyi reached out, saying: 「Right angle……」.

Before he finished speaking, the right-angle clamp slapped into his palm.

Because they needed to do extracorporeal circulation, Zheng Ren worried that Xie Yiren couldn't keep up with the operative steps.

But unexpectedly Xiao Yi Ren was still proficient; he lifted his head, smiled with narrowed eyes at Xiao Yi Ren.

Waiting for him were a pair of smiling eyes.

Their four eyes met, Zheng Ren forgot he was still in the live broadcast.

The doctors watching the surgery live broadcast instantly exploded!

Doing surgery, sprinkling dog food—simply intolerable!

「Boss, the live broadcast. 」 Su Yun reminded.

「……」 Zheng Ren lowered his head, looked toward the operating field again.

Just a moment ago, who knows how many doctors watching the surgery live broadcast witnessed it firsthand.

This is the dream of many surgeons: to have a gentle and lovely instrument nurse, with mutual understanding.

Even if the surgery isn't as good as the surgeon's, they still have a good instrument nurse, and she even smiles at him!

This wave of sprinkled dog food, resentment from all over the world surges to the heavens.

Zheng Ren didn't know what the doctors watching the live broadcast were thinking; he used the right-angle clamp along the inner side of the superior vena cava to loop the band behind it. Using the same method, he used the inferior vena cava band clamp to loop the band around the inferior vena cava, as a backup.

「Lao He, ready? 」 Zheng Ren asked.

「Ready, can start anytime. 」 Lao He said in a low voice.

For this surgery, he adjusted his condition to peak level, wanting to show himself in front of Zheng Lao Ban.

Opportunity is rare, fleeting in an instant.

Having received Lao He's response, Zheng Ren did not lift his head.

As he reached out, the needle holder slapped into his palm. At the same time, Lao He pressed the timer's button.

At the distal end of the ascending aorta, use No. 7 thread to make two concentric purse-string sutures.

The purse-string suture technique is extremely delicate; the small needle only penetrates the vessel's outer layer, yet does not penetrate the vessel, sewing the No. 7 thread around the aorta's outer membrane.

「Boss, I thought you'd use a microscope. 」 Su Yun said.

「No need, the aorta is thick enough; using a microscope would take too long, I'm worried my vestibular nerve can't handle it. 」 Zheng Ren said.

This is Zheng Ren's Weakness; riding a roller coaster makes him dizzy. In microsurgery, a slight movement makes his vision blur like on a roller coaster, his field of view rapidly shifting.

Although he doesn't have that sudden up-and-down feeling, Zheng Ren still tries to avoid too much microsurgery time.

Zhao Yunlong silently watched Zheng Ren leave a purse-string suture on the aortic outer membrane, then fell silent.

Having done similar operations himself, when was he ever not careful?

Although the aorta is thick, the gap between its outer membrane and the aorta is minuscule enough to make one's hair stand on end; a little inattention and blood will spurt.

Although it won't cause death, hemostasis is especially troublesome, and the surgery time is indefinitely prolonged.

Watching Zheng Lao Ban's operation, he makes the difficult look easy; the recent difficulty posed no problem for him, just a routine operation.

Zhao Yunlong had been worrying about Zheng Ren's extracorporeal circulation surgery skill, but after just a glance he understood roughly.

Skill, stronger than his own by a geometric order.

Zheng Ren's purse-string suture has one opening on each side, left and right.

He slipped the purse-string suture into the hemostatic clamp, preparing to use it for hemostasis and fixation during cannulation.

He removed the outer membrane of the central part of the purse-string.

「Heparin, 3 mg/kg. 」 Zheng Ren said.

「Already prepared. 」 Lao He said. He knew Zheng Lao Ban was worried about his own inexperience, but such detailed instructions obviously seemed a bit disparaging, Lao He muttered to himself.

Zheng Ren smiled, then after injecting heparin into the right atrial appendage, he used the Willow Leaf Blade to make a cut slightly smaller than the arterial cannula diameter in the center of the purse-string, withdrawing the blade while simultaneously inserting the arterial cannula into the ascending aorta incision.

At the same time, Su Yun immediately tightened the hemostatic clamps on both purse-string sutures, and used thick thread to fix the arterial cannula to the hemostatic clamp.

Finally, he secured the arterial cannula to the edge of the incision or the retractor's lever, then connected the cannula to the heart-lung machine.

Similarly to this step, Zheng Ren then sewed a purse-string suture on each of the right atrial appendage and right atrium, and placed hemostatic clamps on them.

Then he made an incision, inserted the superior and inferior vena cava cannulas, and tightened the hemostatic clamps.

He wrapped thick thread around the cannula to ligate the atrial appendage and atrial wall 2–3 mm below the incision, and used this ligature to secure the superior and inferior vena cava cannulas to prevent slipping. Then he connected the superior and inferior vena cava cannulas to the heart-lung machine.

Lao He watched the operation on the Operating Table while also monitoring the time.

He had performed at least several hundred extracorporeal circulations. An extracorporeal circulation specialist can judge the surgeon's skill from the process of establishing extracorporeal circulation.

3′12″……

This is a time that makes one's hair stand on end.

What was the previous record? Although not finished, Lao He was sure Zheng Lao Ban could easily break the national record.

Of course, this record has no official certification.

The extracorporeal circulation technicians from the large tertiary Hospital in Di Du and Modu have a group; in the group, everyone records the time when the top experts in their respective Hospital established extracorporeal circulation.

Only with comparison does harm arise.

Anyway, they're not the ones being harmed. If a lead doctor has a particularly heavy workload and still thinks highly of his ability, he can just use the data to slap someone down.

Lao He felt pleased inside, but he didn't smile; instead, he glanced at the time on the timer and then got back to work.

Probably in the future, when others perform extracorporeal circulation, they'll only be able to drive honestly and amiably, chatting and telling little jokes. With this number here, who would dare to show off?

Do they still have any shame?!

Zheng Lao Ban's hand speed is too fast, and extremely Stability.

If one is slightly inattentive, it will delay the Shou Bing progress. However, Lao He felt pleased inside—that is, himself; if it were someone else, by now they would have already started delaying the Shou Bing.

I don't know whether Zheng Lao Ban can realize his own value; Lao He thought to himself.

What twin sister flowers? Can they wear Lead clothing into the Operating Room? Can they cooperate so skillfully in extracorporeal circulation?

Impossible!

Zheng Ren didn't know what Lao He was thinking; he was silently performing the Shou Bing.
