Chapter 2201: 2125 An Expected Sudden Stop (Brother Yun's Birthday Happy Extra Chapter ×1)

Based on measurements of liver injury biomarkers, the team found that normothermic mechanical perfusion reduced liver injury by 50% compared to cold storage, increased average preservation time by 54%, and lowered organ discard rate by 50%.

Besides having a liver with matching blood type and match, they also transported the donor liver using a life-support system at normal temperature over a long distance.

Thinking of this, Li Zhu ren couldn't help but feel a bit dazed, wondering if the world had achieved great unity.

Achieving this is actually possible—one must have an extremely high status in academia. At the very least, doctors at top hospitals worldwide need to buy in; otherwise, no one would do it.

Looking at the liver taken out of the life-support system, full of vitality, the entire operating room was solemn.

When Xie Yiren received the donor liver, it was just cut off, seamlessly connected, with no delay.

Li Zhu ren stared in disbelief; this was the ideal situation for a liver transplant.

The harvested donor liver, without blood supply, would undergo tissue changes even if deprived of blood for just one more minute.

Although everyone knows seamless anastomosis is best, there may be no surgeon capable of doing it.

Li Zhu ren stood on the operating table as an assistant; his rich experience let him notice details many others could not.

Such details filled every corner of the surgery; Li Zhu ren wasn't even sure he fully understood them all.

For the chief of hepatobiliary surgery at 912 with rich liver transplant experience, his hand speed might not be as fast as a young person's, but if he couldn't even understand the surgery, that would be too much.

Zheng Ren installed the vascular anastomosis magnetic rings one by one, while Li Zhu ren kept watching the time. The anhepatic period should definitely be as short as possible, which no one can deny.

But Zheng Lao Ban had never touched a vascular anastomosis magnetic ring before—how could he be so skilled!

"Lao He, start dopamine with a micro pump." Zheng Ren said while performing the surgery.

"8 ml per hour." Lao He replied.

"Prepare to push dopamine intravenously, have ten epinephrine shots ready." Zheng Ren said.

"..." Li Zhu ren stared blankly at the ECG monitor, where all readings were steady.

What is Zheng Lao Ban trying to do?

The ECG showed sinus rhythm at 124 beats per minute. The rapid heart rate was considered due to acute liver failure or infection-induced toxic shock, and this was still the result of the efforts of 912's top critical care team.

After one rescue, the patient's condition slightly improved; at least, in Li Zhu ren's view, there were no immediate problems.

They say the older the jianghu, the smaller the courage.

Zheng Lao Ban was exactly like a youthful white-horse hero, wielding his sword across the land, yet he was this careful and cautious—indeed interesting to watch.

It was time to transplant the liver; Li Zhu ren knew what to do, shifting his gaze from the ECG monitor to the operative field.

But,

At the instant his gaze shifted,

he felt as if he were having a hallucination.

The ECG waveform fluctuated violently—had he misread it? Li Zhu ren stared for a moment.

"Dopamine, epinephrine." Zheng Lao Ban gazed at the operative field but said in a low voice.

Three seconds ago, he had already opened the portal vein.

Immediately after opening the portal vein flow, patient Chen Li's vital signs began to change.

Uh…… Li Zhu ren froze.

He immediately turned his head to look; the arterial pressure monitor fell like a drop, the numbers swooping down.

Just a moment ago it was 90 mmHg, but in the instant he turned his head back, it dropped to 62 mmHg.

"Pop." Li Zhu ren's hand twitched slightly, and Zheng Ren's hemostatic forceps tapped Li Zhu ren's hemostatic forceps.

"Li Zhu ren, focus; we don't have much time." Zheng Ren said in a low voice.

Li Zhu ren felt a chill.

It was obvious that Zheng Lao Ban had his own plan and prediction for the entire surgery.

Time is short…… what he meant wasn't the ordinary term of the organ's normothermic period, but that the patient was really about to give out!

Since Zheng Lao Ban had confidence, Li Zhu ren stopped pondering other things and began to cooperate wholeheartedly with Zheng Lao Ban's surgery.

At the moment the portal vein was opened, Su Yun stopped looking at the operative field and instead stared tightly at the ECG monitor.

Blood pressure plummeted cliff-like, arrhythmia, rapid atrial fibrillation.

There wasn't even time to give medication; blood pressure and heart rate went straight to zero.

After restoring venous return, the patient's heart, already in heart failure, could not withstand such pressure and stopped beating outright!

The ECG waveform went from wild trembling to weakly moving twice, about to flatten into a straight line.

The boss's judgment was damn accurate! Su Yun felt a little surprised.

But the boss's accurate judgment—shouldn't that be expected? Su Yun, at some point, also developed a set mindset.

Saying it went to zero is an exaggeration; arterial pressure monitoring showed arterial pressure dropping rapidly, mean arterial pressure 20 mmHg.

"Both pupils dilated, diameter 4mm, light reflex gone." Lao He had been ready; from the moment the ECG monitor alarm started, he began observing the patient's pupils.

Su Yun extended his right hand from the incision into the subdiaphragm, placing his 2-5 fingers together on the posterior inferior diaphragmatic surface of the heart, and put his left palm on the previously reserved dressing spot, knowing that underneath was the middle-lower third of the patient's sternum.

He fixed his left palm, using coordinated motion of the right elbow, wrist, and shoulder to drive the right hand's 2-5 palm fingers in rhythmic, impactful lifts toward the sternum, raising the diaphragm 5.5 cm, then quickly relaxing to let it return to its original position.

The whole maneuver was standard, like a machine, with no deviation.

Although Su Yun's movements were forceful and impactful, the patient's body remained completely still.

Not only the whole body, but even the liver nearby being transplanted didn't twitch.

Zhang Jiaoshou stood aside, dumbfounded.

The sudden cardiac arrest seemed as if the patient's heart rate had been transplanted onto his heart.

The steady 80 beats per minute heart rate instantly rose above 150. Finally, was it his turn to go on stage?

There was no excitement, only a hint of embarrassment.

Zhao Yunlong this guy—how could he just stand there? Zhang Jiaoshou was somewhat dissatisfied; shouldn't he be scrubbing up, preparing for thoracotomy, and doing direct chest compressions right now!

He bumped Zhao Yunlong with his arm.

「Xiao Zhao, swipe hand. 」

「Eh... 」 Zhao Yunlong stared unblinking at Su Yun's action, merely letting out a sound from his nasal cavity.

What kind of attitude is this? Zhang Jiaoshou hasn't yet noticed Su Yun's action; he is very dissatisfied with Zhao Yunlong's reaction.

But Zhao Yunlong didn't move, and yet Director Zhang also didn't move!

After 1.2 seconds, Zhang Jiaoshou then noticed that the already straightened electrocardiogram waveform had a Fluctuation again.

That Fluctuation signifies the continuation of life. However, the waveform is not that of sinus rhythm, but a standard ejection waveform.

CPR? Zhang Jiaoshou froze.

No one was seen doing external chest compressions; who performed CPR!
