Chapter 1496: 1449 Making a Fuss Like Being Pregnant (Sect Leader magang111 Bonus)

Yo, Boss, you've gotten this far? Su Yun glanced at the operating field and said in surprise.

Hmm. Zheng Ren said in a low voice.

You're doing it this fast—why do you need hypothermia?

I'm worried there might be an abnormality, or maybe hypothermia just makes me feel more at ease. Surgery—once the condition is up and things go smoothly, it goes relatively faster. Zheng Ren said calmly while performing the surgery.

Actually, in the System Operating Room, Zheng Ren simply can't keep up by himself.

So he's gotten used to hypothermia.

If I'd known the assistant, instrument nurse, and anesthetist could cooperate this well, I wouldn't have bothered with hypothermia at all.

After chatting a while and hearing Lin Ge gossip, Zheng Ren had already dissected the blood vessel intima and reached the pulmonary valve position.

He opened the intima and directly excised the pulmonary valve under direct vision.

This isn't a simple pulmonary valve stenosis surgery or a valve replacement; just removing the pulmonary valve and then implanting a prosthetic or autograft valve is enough.

Removing the valve, Zheng Ren also cut away the tumor tissue attached to the blood vessel intima along the valve.

Under direct vision, his movements were so slow you could hardly feel his hands moving.

Su Yun also fell silent, quietly watching Zheng Ren's surgery, then began helping to retract the pulmonary artery to assist in extracting the tumor tissue.

Although they reached this step quickly, just taking the tumor tissue took nearly thirty minutes.

Finally, along with the hemostatic forceps, the tumor tissue was excised.

Thrown into the pathology basin, the hemostatic forceps struck the metal basin's edge, producing a crisp sound.

The main part of the surgery is finished; all that's left is to implant the prosthetic valve.

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

"Old Zhao, you haven't even done anything—why are you sweating so much?"

Zhao Yunlong said nothing, continuing the surgery with a stern expression.

"Old Zhao, that's your flaw—you refuse to speak during surgery." Su Yun, while assisting Zheng Ren, said disparagingly, "Next time I'll have Fang Lin assist instead; even a blockhead like him would be better than you."

"Fang Lin couldn't handle it." Zhao Yunlong, wholeheartedly assisting Zheng Ren, said, "Thoracic surgery—can just anyone do it?"

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

"Not bad." Zheng Ren began clearing the calcified lesions.

The pulmonary valve has three leaflets, leaving a 2mm margin at the edges. Zheng Ren excised the valve, then cleared the calcified tissue on the annulus, using a sizer to measure the annulus to determine the prosthetic valve size.

Zhao Yunlong brought up various valves; Zheng Ren selected one, the circulating nurse opened it, and Xie Yiren handed it over.

"Suture." Zheng Ren reached out.

Xie Yiren immediately slapped the opened suture needle—a 2-0 nylon thread with double-armed needles and supported pads—into Zheng Ren's hand.

He performed an interrupted horizontal mattress suture from top to bottom, immediately suturing through the annulus then onto the prosthetic valve's sewing ring, Zheng Ren paying close attention.

The suture must be evenly and proportionally distributed on the annulus and the prosthetic valve sewing ring, with a 2mm bite.

"Boss, your hand is rock‑steady—nice." Su Yun said.

Not bad.

"Next time just let Old Zhao assist you—that'll be enough; this surgery is too oppressive." Su Yun said that, but her hands didn't stop for a moment as she helped Zheng Ren thread the suture and press the valve.

The 2mm suture spacing was as if measured with a ruler.

"Boss Zheng, your skill is truly impressive." Lao He looked on and sighed.

"What's up, Lao He? You mean my surgery isn't good?" Su Yun gave Lao He a disparaging glance.

"Doctor Su, three years ago when you saved Boss Zhao's case, I wasn't the anesthetist, but I saw your surgery." Lao He said seriously, "Back then I saw it and was amazed."

Su Yun didn't get smug; his words obviously had more to come.

"But the suture spacing in the anastomosis—Doctor Su doesn't seem to have reached that ruler‑measured level yet," Lao He said.

"It's completely unnecessary." Su Yun said disparagingly, "As long as it's sewn shut and doesn't bleed, a few micrometers' difference—why go to such trouble? You think I can't do it?"

"Heh heh." Lao He gave a dry laugh, clearly thinking differently.

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

"Doing valve surgery, I hate this terminology—it's like making a fuss as if I were pregnant." Su Yun muttered.

At this point, implantation is not the same as embryo implantation.

Zheng Ren was clearly in a world of his own, utterly oblivious to what Su Yun was saying.

He straightened all the sutures, pushed the prosthetic valve beneath the annulus, and confirmed the implantation was seated.

After repeatedly confirming the prosthetic valve wasn't blocking the left or right coronary artery ostia, Zheng Ren finally relaxed.

Each of the three took a suture and tied them off one by one.

Zheng Ren finally checked once more, confirming the left and right coronary artery ostia were patent, with no stenosis caused by the suture knots.

This is a critical point; otherwise, after the surgery is finished, the patient would immediately show symptoms of myocardial infarction.

"Irrigate." Zheng Ren said.

A basin of ice‑cold saline was passed over.

Zheng Ren thoroughly flushed the prosthetic valve's aortic and ventricular sides, filling the aorta and left ventricle with physiological saline.

"Suture."

The needle holder gripping a 5‑0 suture was slapped into Zheng Ren's hand.

He ran a continuous suture across the two pulmonary artery incisions, tightened the final stitch, then performed de‑airing.

If any gas remained here, it would be an iatrogenic air embolism.

Surgery truly cannot afford to miss even the tiniest detail; otherwise, such a small oversight would cause the patient's death.

After venting the right heart and pulmonary artery, the pulmonary artery clamp was opened.

Maintain right‑heart drainage to prevent distension. Because of the hypothermia, the heart's spontaneous restart is unlikely, so Zheng Ren directly used electrical defibrillation to restore rhythm.

The heartbeat recovered, seeing the heart beating well, everyone let out a sigh of relief.

After recovery, the heart was made to beat without load for a period of time, with no problems at all.

Zheng Ren opened the blockage of the superior and inferior vena cava, entering parallel circulation. After a period of auxiliary circulation, meeting the bypass cessation conditions, Lao He promptly stopped the machine on his side.

"Come over here." Zheng Ren turned and stepped down.

"Boss, this typhoon of yours is getting worse and worse." Su Yun muttered.

"I'm not in a hurry to look at the pulmonary artery valve tumor, am I?" Zheng Ren emerged from his state of focused wisdom, smiled, and said: "Pulmonary artery valve tumor, have you seen one?"

"No." Su Yun began searching for the bleeding point with Zhao Yunlong, sutured the pericardium, left a drainage tube, and closed the chest.

Shou Bing went smoothly; after the patient's heartbeat recovered, blood oxygen saturation reached 100% while breathing pure oxygen.

It was fine; Lao He directly determined that. Hu Yan Hui stopped the livestream, came in, and removed Zheng Ren's livestream glasses.

Zheng Ren came to the side of the pathology tray and carefully examined the excised tumor.

Lao He leaned over to Zheng Ren, chuckling, and asked: "Zheng Lao Ban, I thought you'd need ultra-low temperature; the surgery would have to take at least four hours."

"It's not that; your cooperation was good, the extracorporeal circulation went smoothly, unexpectedly smoothly." Zheng Ren held a Willow Leaf Blade and dissected the tumor tissue in the pathology tray.

Lao He felt pleased.
