Chapter 975: with translation of chapter title

Professor Yang came the earliest, his position was the best.

When he saw the opened peritoneum and a belly full of spleen, his head buzzed.

Although he had expected it, the visual impact of seeing it with his own eyes was completely different from watching a video or imagining it himself.

He felt a bit regretful.

If he had known it would be like this, he shouldn't have let Zheng Lao Ban do the surgery live broadcast.

With good intentions, he ended up causing Zheng Lao Ban a lot of trouble; what's the point?

Many thoughts arose in his mind; after a brief dazed moment, he saw Zheng Ren begin to block the splenic artery.

"Lao He, please monitor the patient's arterial pressure," Zheng Ren said softly.

This was what Zheng Ren had previously requested; Lao He performed a radial artery puncture, which provides invasive arterial pressure measurement.

The advantage of invasive arterial pressure monitoring is that it directly monitors arterial pressure as a continuous dynamic process, unaffected by manual compression, cuff width, or tightness; it is accurate and reliable, and values can be taken at any time.

Moreover, it allows analysis of myocardial contractility based on arterial waveform changes, preventing excessive venous return that could lead to acute cardiac dysfunction in the patient.

As for other benefits, they are not very evident in this surgery.

However, the drawbacks of invasive arterial pressure monitoring are also fairly obvious, such as puncture failure or local infection; Zheng Ren doesn't worry much about them.

Lao He's skill is still solid, though he talks a bit much, like Su Yun, being a bit talkative. If he can't even do invasive arterial pressure monitoring well, he could retire.

"Blood pressure 90/70 mmHg." Lao He knows the importance, keeping his eyes on the arterial pressure.

The patient's blood pressure is on the low side, which Zheng Ren knows. In the System Operating Room, during training he clamped the splenic artery, allowing blood in the spleen to flow back via the vein; he determined the limit through nearly a hundred trials, finally obtaining a standard value.

He lowered his hand and waited quietly.

The color of the patient's spleen masses changed slightly; Zheng Ren watched the color change with his eyes and calculated the time in his mind.

"100/70 mmHg."

"110/75 mmHg."

"115/80 mmHg."

Lao He strictly followed Zheng Ren's request, monitoring the patient's arterial pressure.

After the patient's arterial pressure reached 115 mmHg, Zheng Ren began to operate, cutting sections of the splenic gastro ligament and related ligaments.

Finding the stomach within a mass of spleen and feeling for abnormal tissue structure is difficult, but under Zheng Ren's hands everything proceeded smoothly, just like a routine splenectomy.

"120/75 mmHg."

"125/85 mmHg."

Lao He continued to report the patient's arterial pressure meticulously.

May kind people have Good Luck Come every day~~~

Lao He's voice mixed with the song; he suddenly felt that playing this song during surgery was also quite cool.

Professor Yang felt his view was limited, so he shifted his head sideways to see Zheng Ren's hand movements clearly.

"Professor Yang, make room for me; you've taken the good spots and still want to eat and occupy more, not being like this." A professor beside him said unhappily.

"Did you see the splenic gastro ligament being cut?"

"I can't see; Boss Zheng is probably operating blindly."

Even standing behind the operator, one can't see; there's really nothing to be done about it.

However, the assistant opposite had anticipated this; a large retractor was placed directly on the spleen with just the right force to pull it open, then another retractor was used at the operator's third quadrant 55° angle to pull open the liver and spleen on the other side.

Now the view opened up considerably.

The assistant's left hand moved the retractor slightly; a small, delicate hand wearing a size 5.5 sterile glove took the retractor and then slapped a hemostatic forceps into his hand.

"Boss, it's still more comfortable for Yi Ren to do the surgery here." Su Yun sincerely remarked.

Zheng Renze seemed not to have heard his words, lowering his head to perform the surgery; whenever he reached out, the instrument he wanted would appear in his hand as if by magic.

The more he watched, the more alarmed he became; Professor Yang gradually became dazed.

I had thought Boss Zheng would remove the spleen piece by piece, but unexpectedly, once the arterial pressure reached a certain range, he began cutting directly from the top.

He began to regret again.

If I had gone up myself, I could still remind Boss Zheng now.

Watching surgery requires decorum; if the operator hasn't asked a question, it's best not to speak.

Doing so would disturb the operator's train of thought, causing the surgery to proceed haltingly.

But doing this, is the risk too great?

If removed piece by piece, any problem could be treated as a tumor-reduction surgery; but if cut directly…

Professor Yang felt torn inside, yet he saw Zheng Ren hesitate not at all, directly cutting off the inferior pole of the spleen.

While removing, he also staunched bleeding.

For slightly larger vessels, his hemostatic forceps seemed to have eyes, always able to reach into a pool of blood first and clamp them.

The assistant's reaction was also quick, but slightly slower than Boss Zheng's hand speed. Each time after clamping the vessel, the assistant's suction device would clear the blood, then tie the clamp with thread and knot the instrument.

The instrument knot was also done with great care: one coil, one wrap, and it's done. The blunt scissors held in the operator's palm cut the suture to an appropriate length.

As for extensive oozing, electrocautery was used to stop bleeding.

A barbecue-like smell spread; the assistant's view was limited, so he simply used the suction device to draw away the smoke from the electrocautery.

"Boss, there's a lot of bleeding today." Su Yun said.

"There's nothing to be done; cutting the spleen definitely causes bleeding." Zheng Ren said.

Professor Yang and the directors and professors on the observation platform were all astonished.

Bleeding? The estimated blood loss so far is still under 100 mL, and that's considered a lot?

What a joke!

Under normal circumstances, when the spleen is ruptured with a small tear, some surgeons are willing to suture it; but the vast majority would rather have the spleen removed than sewn up.

Not for any other reason, only because the spleen has abundant blood supply and its texture is very fragile, even more fragile than the kidney.

The suture is done, but no one dares to guarantee that there will definitely be no postoperative bleeding. Once bleeding occurs, the abundant blood supply will lead to incessant bleeding.

If monitoring is not timely, there is a risk of the patient developing hemorrhagic shock, which could then lead to the patient's death.

Even suturing a small laceration requires utmost caution, let alone this cross-sectional splenic resection.

At the incision site, if just a small Artery bleeds, amidst a pool of blood, even the Suction Device cannot suck all that blood clean.

Under such circumstances, it is very difficult for the surgeon to locate the bleeding point.

If the instruments are not easy to handle, being those from a small domestic manufacturer, even clamping the Blood Vessel cannot guarantee complete occlusion.

It is possible that the surgery is declared a failure right at the outset.

Zheng Lao Ban's Shou Bing, with remarkably little bleeding that is astonishing, the Operating Field is spotless; it is estimated that doctors watching the Surgery live broadcast on their phones can see very clearly.

But even so, the assistant is still complaining about excessive bleeding.

Does he even understand at all!
