Chapter 2763: 2565 Really Damn Valve Stuck (Alliance Leader Blowfly Bonus Chapter 2)

"Is this the little Zheng Boss from 912?" Director Xu asked doubtfully.

"Mm." Zheng Ren nodded.

"How did you come!" Director Xu was delighted and surprised; the previous unhappiness of asking him to reopen and take a look vanished.

Seeing Director Xu about to step down, Zheng Ren hurriedly said: "Director Xu, the operation isn't over yet! Let's open and have a look."

"Oh, oh."

This time Director Xu didn't insist at all; his principles and stance flew off together with his previous anger into the clouds.

"Zheng Boss, long admired." Director Xu suppressed his excitement and said: "What's up with Director Qiu? He's just an anesthetist."

"How are you speaking?" Director Qiu said unhappily.

Zheng Ren saw Director Xu beginning to twist the wire in reverse, and glanced at the ECG monitor's waveform and radial artery pressure curve, feeling there was still time.

"You're welcome." He said lightly, then added: "Don't withdraw the extracorporeal circulation; get ready to re-establish it immediately!"

The extracorporeal circulation technicians were dumbfounded; the legendary Zheng Boss?! For a full six hours, they couldn't see anything different.

No, not allowing the chest to be closed—this is a big deal. Both Director Xu and Director Qiu on stage didn't notice any abnormality; yet at the last moment they refused to close the chest—what's going on? Suppressing their feelings, a last-minute slap in the face?

No, no, the extracorporeal circulation technicians immediately cleared their messy thoughts. Zheng Boss said there was a problem; if they opened and found nothing, it would be them slapping themselves in the face.

Seeing Director Xu's face full of admiration, Su Yun noticed his hand twisting the wire slightly trembling, found it amusing, and said: "Director Xu, keep your hand steady, seize the time."

"Oh, oh, don't worry." Director Xu became gentle like a different person, no longer cold as ice, and responded like an intern.

"Zheng Boss, what's going on?" Director Qiu whispered in Zheng Ren's ear.

"The ECG waveform and radial artery pressure curve don't match; consider the mitral valve..."

Zheng Ren Gang had just spoken half a sentence when the ECG monitor alarm blared, and then the ventilator began issuing sharp alerts to warn those in the operating field of an abnormal situation.

"Hurry up! Prepare the extracorporeal circulation." Zheng Ren had long switched to surgeon mode; in this room he was the one and only king!

Although still unclear, everyone in the operating field sprang into action. Director Xu didn't have time to express his admiration to Zheng Boss and Su Yun, and hurriedly twisted the wire open.

At this moment the blood pressure plummeted, the arterial waveform peak dropped and gradually became a straight line.

"Dopamine, increase speed."

"Epinephrine, 1 mg intravenous injection."

"Give another dose of epinephrine!"

"Hold onto the extracorporeal circulation, prepare to re-establish it."

"Speed up the chest opening! Follow the valve replacement incision."

Orders were issued one after another, and the previously tranquil atmosphere of the operating room vanished.

Director Qiu and the circulating nurse were busy, buying time, their feet barely touching the ground as if they were flying.

We dread this situation; fortunately Zheng Boss reminded us, otherwise just twisting the wire would take ten minutes. During this period we had to rely on drugs to maintain the patient's vital signs; judging by the blood pressure, the drugs had a slight effect at first, but soon became useless.

Vasopressor drugs struggled to maintain the patient's blood pressure, averaging 20–30 mmHg, while heart rate rose to 120–130 beats per minute. Moreover, the patient's left-hand SpO2 waveform matched the right radial artery pressure waveform, also forming a straight line.

A straight line—what it means needs no explanation; everyone present knows.

MD, what the hell happened!

After 20 seconds, the waveform slightly recovered. But before everyone's tension could ease, a straight line appeared again in the field of view.

This situation recurred, with intervals growing shorter, heart rate rising to 120–150 per minute, and the radial artery pressure catheter's drawback flow was smooth, indicating the radial artery pressure line was normal—not a machine problem, but something truly wrong!

Director Xu opened the chest as fast as possible and began establishing extracorporeal circulation. Thanks to the earlier reminders from Zheng Ren and Su Yun, this time was shortened to a certain extent.

"Measure the aortic root pressure!" Zheng Ren said in a deep voice.

Director Xu immediately began measuring the patient's aortic root pressure, just like the radial artery... his sweat poured down again.

Zheng Boss wasn't speaking baselessly; he had seen an abnormality. Damn it, where did things go wrong?! Director Xu felt his hands turn ice-cold, the actions before him became extremely slow, as if he had entered another world.

Not only were the aortic root pressure and radial artery consistent, the aortic root softened, and the biological valve's leaflet sounds disappeared—this all meant one thing: the site of the recently replaced valve truly had a problem!

Emergency establishment of extracorporeal circulation, a second chance.

Because there had been a prior warning, the preparation time of the extracorporeal circulation machine didn't delay the surgery. After opening the heart, the posterior chordae of the mitral valve ruptured from the ** muscle, causing the chordae to lodge in the prosthetic valve, resulting in valve entrapment.

Really, it's valve entrapment! Directors Qiu and Xu looked helplessly at the scene before them, a sense of dread welling up.

The free chordae were excised, and the original biological valve was sutured continuously. The handling wasn't difficult, at least for Director Xu. The final difficulty lay in the coordination between surgeon and anesthetist.

After noticing an abnormality, whether the anesthetist had a clear idea in mind was key to promptly reminding the surgeon. Under the pressure of the surgeon's strong presence, not all anesthetists could stick to their judgment and promptly reopen the chest to investigate the abnormality.

Mitral valve chordae rupture leading to valve entrapment is an uncommon complication of valve replacement surgery.

This occurrence might be related to the patient's heart failure; Director Xu felt somewhat innocent, and after the valve replacement he carefully observed for a few minutes, seeing that the mitral valve chordae didn't seem problematic, before proceeding to the next step.

Who would have thought that something would go wrong after closing the chest.

Damn it! If being a doctor were just this, there'd be pits everywhere; who knows which hole will bury you one day.

After urgently cutting the mitral valve chordae, the biological valve resumed working, and the instrument alarms ceased.

What remained was routine procedure. Director Xu looked up at Zheng Boss and whispered: "Zheng Boss, thank you."

"You're welcome." Zheng Ren also exhaled. Initially noticing the ECG waveform and radial artery pressure curve hinting at a problem, he only confirmed something was wrong after entering the system operating room.

But why is that Su Yun so determined?

Zheng Ren glanced at Su Yun with some doubt.

"What are you looking at me for?" Su Yun was recording the anesthesia sheet, as if sensing something, and lifted his head to glance at Zheng Ren.

"How did you determine that?"

"There's a problem, but I'm not sure. Seeing you so certain, I became certain too—it's a simple matter." Su Yun said, "Even if we reopen the chest mistakenly and waste half an hour of surgery, we'll just slink back."

Zheng Ren spread his hands.
