Chapter 1855: 1790: As Long as There Is a Glimmer of Hope, Do Not Give Up (Alliance Leader LUCKY Bread Tree Bonus Chapter 5)

Returned to the ward, Su Yun stood beside the patient, staring intently at the ECG Monitor.

"How is it?"

"Not optimistic." Su Yun said, "IABP can't let the heart get enough rest."

Zhao Yunlong placed the Signature Form into the patient's chart; Su Yun caught a glimpse and finally breathed a sigh of relief.

"Director Lin will be here soon, Boss, what are you preparing to do?" Su Yun asked.

"Let me think." Zheng Ren didn't directly answer Su Yun's question, but instead inserted the patient's Nuclear Magnetic Resonance image into the viewer.

Smog Disease is a cerebrovascular disease of unknown cause, characterized by chronic progressive stenosis or occlusion of the bilateral internal carotid artery terminals and the origins of the anterior and middle cerebral arteries, with secondary formation of an abnormal vascular network at the skull base.

Because this abnormal skull-base vascular network resembles "smoke" on cerebral angiography images, it is called Smog Disease.

Nuclear Magnetic Resonance clearly shows the pathological changes in the patient's cerebral blood vessels: old cerebral infarction, localized brain atrophy most prominent in the basal frontal and temporal lobes, and the abnormal vascular network at the skull base appears as a honeycomb or reticular low-signal vascular image due to flow void effect.

For the more apparent Smog Disease, Zheng Ren looked at that clump of proliferating blood vessels resembling smoke exhaled after smoking, feeling somewhat worried.

Forget it, regardless of how the patient's family chooses, let's still go to the System Operating Room to give it a try.

Although the hope of saving the patient is not great, as long as there is a sliver of hope, Zheng Ren does not want to give up.

If the patient could be saved in the System Operating Room, Zheng Ren would also want to try it despite the enormous risk.

Big Pig Trotter is simply too hateful—such a serious illness, and yet no mission is issued?

Zheng Ren habitually placed his left hand under his right armpit, right hand supporting his chin, and looked at the patient's Nuclear Magnetic Resonance image.

After making his decision, he directly entered the System Space.

When clicking to purchase Surgical Training Time, Zheng Ren hesitated slightly.

If the patient's family disagrees with any surgery, the Surgical Training Time I purchased would be wasted. Moreover, this is not a General Surgery Department procedure—it's a neurosurgery Shou Bing I've never performed before!

At least I would also have to "waste" a Master-level Skill book.

Earlier, while completing missions, I had accumulated three Master-level Skill books as rewards. At that time, Zheng Ren thought he would use them for a long time, but he never expected to need the last one so soon.

I am about to go to Europe, facing an ancient, mysterious vampire family...

But if the patient's family agrees, yet I cannot solve this problem with surgery, what then?

After hesitating for less than a second, Zheng Ren made his decision.

He selected to purchase Surgical Training Time and clicked to use the last Master-level Skill book.

Neurosurgery Shou Bing is the most delicate of all surgeries.

When Zheng Ren was in school, he heard the Teacher say that in the past, when conditions were poor, after burr hole drainage they would leave a drainage tube in place. When the drainage tube became blocked, they usually applied negative pressure to drain the excess fluid.

But this very act of applying negative pressure could possibly suck out several milliliters of brain tissue.

Consequently, due to the loss of this brain tissue, the patient may experience postoperative inability to speak, hemiplegia, weakness in walking, and so on.

Therefore Zheng Ren has always avoided neurosurgery Shou Bing; to him, it is a very difficult procedure.

But today there's no choice; he must try it no matter what.

After all, it's a Master-level Skill; it should be fine, Zheng Ren thought to himself.

In 1967, Yasargil first successfully anastomosed the superficial temporal artery to the middle cerebral artery to treat cerebral ischemic disease; thereafter many countries have carried out this type of surgery.

Zheng Ren simply doesn't believe his surgical technique could still be inferior to the surgical standards of the 1960s-70s.

After entering the System Operating Room, Zheng Ren saw the experimental subject lying on the operating table.

He didn't rush into surgery; instead, he first observed the subject's position. After all, it's an unfamiliar neurosurgery Shou Bing—no matter how cautious, it's necessary.

The system adopts endotracheal intubation under supine position while administering intravenous drugs for general anesthesia, and uses radial artery puncture to connect to an invasive arterial pressure monitor, allowing timely observation of intraoperative blood pressure fluctuations, providing a reliable basis for controlling and adjusting blood pressure.

Being able to monitor arterial pressure anytime, anywhere, it seems Big Pig Trotter is also very careful; Zheng Ren made that judgment.

The subject's head was tilted toward the healthy side, with a Microscope placed in the operating field.

Zheng Ren glanced at it—it was a Zeiss! He felt a little excited.

According to Su Yun's description, the Zeiss Microscope can let him avoid as much as possible the trouble of an underdeveloped vestibular nerve.

Otherwise, after each microscopic Shou Bing, he would feel as awful as riding a roller coaster.

Zheng Ren hates roller coasters!

It should be fine—let's start the surgery. Thinking this, Zheng Ren noticed the experimental subject had already completed the skin preparation.

In neurosurgery, skin preparation means shaving the head; an experienced nurse can shave quickly and smoothly, while an inexperienced one either leaves some hair or cuts the scalp.

Zheng Ren glanced and saw that Big Pig Trotter was an experienced nurse; the skin preparation was nearly perfect.

Routine brain surgery disinfection, covering with sterile dressing, injecting local anesthetic subcutaneously around the incision margin, and making a wing-point incision to cut the scalp and subcutaneous tissue with bipolar hemostasis.

The scalp's blood supply is incredibly rich; although Zheng Ren possesses Master-level Shou Bing skill, he was nurtured by the system and is not proficient. At this step, he wasted a considerable amount of time.

Subsequently, Zheng Ren began to dissect the superficial temporal artery, making a monopolar incision in the temporal muscle's upper part and covering it with saline gauze for protection.

Using the AO power system and a burr to remove the skull bone flap, cutting open the dura mater, and under the Microscope dissecting the middle cerebral artery and its branches.

The Microscope is good, 40× magnification; Zheng Ren's every move is very careful and cautious.

But after all, it's his first time doing this; he failed at this step twelve times.

Shou Bing failed, the experimental subject died...

Shou Bing failed, the experimental subject was paralyzed...

Zheng Ren has almost become numb to these kinds of prompts.

However, having experience with microscopic Shou Bing, the narrow scope of neurosurgery Shou Bing and the characteristic of making microscopic movements as gentle as possible, he quickly mastered it completely.

On the thirteenth Surgical Training session, Zheng Ren finally completed the dissection step perfectly.

Selecting an appropriate recipient, he performed an end-to-side anastomosis of the superficial temporal artery's stump to the middle cerebral artery, suturing under the Microscope with 10/0 Prolene line, repeatedly flushing the operating field and lumen with a soft needle tipped with heparin saline during suturing to prevent thrombosis.

After completing the anastomosis, he thoroughly flushed the operating field, flipped the dura, counted the surgical supplies, and affixed the inner layer of the temporal muscle to the dural surface, securing it to the dura at the bone edge.

He replaced the bone flap, sutured the scalp with 3/0 absorbable thread, and covered it with an iodine gauze head wrap.

Shou Bing completion degree, 50%!
