Doctor: Picking Up Attributes in the Hospital-Chapter 368 - 336: First Treatment Completed, Strange Howling Sounds (Part 2)
The highest level in a laminar flow operating room is the hundred-level laminar flow operating room, equivalent to the standards of a space laboratory.
To maintain such a high standard of air cleanliness, the purification measures must indeed be very strict. Generally, a ten-thousand-level laminar flow operating room requires at least 600 air changes per hour, equipped with high-efficiency air filters that can remove ninety-nine percent of dust and most bacteria from the air. There must also be strict air disinfection and purification, as well as features like thermal insulation, humidity control, and soundproofing.
Thus, just constructing this operating room requires extremely high technical expertise.
Not to mention the carbon nanotubes to be used next, which represent the peak and forefront of modern technology.
At this moment, Ma Xiaochen, lying on the sterile operating table, has already undergone mild anesthesia and is gradually slipping into sleep.
Zhao Heng and Liu Ziang are waiting for the anesthesia to fully take effect.
"Junior, I didn’t expect that you, an anesthesiologist, have gone further in the treatment of brain tumors than I have."
Liu Ziang said, sighing heavily.
He had watched Zhao Heng rise step by step, and the process had been amazingly fast.
"Brain science is the jewel of medicine and the most difficult. At our current progress, you could say we’re just beginning to take a small step."
Zhao Heng shook his head slightly and said, it’s precisely because he has gone further than most doctors that he deeply understands that in terms of medical development, he’s only taken a small step.
Just talking about the brain, the most extraordinary thing in the universe, modern science still remains in the preliminary phase of brain research.
Even if you traverse every inch of outer space, you may not find anything more marvelous, complex, or powerful than those two and a half pounds of spongy matter inside a human skull.
The greatest paradox about the brain is that everything you know about the world comes from an organ that has never seen this world firsthand.
The brain exists in silence and darkness, like a prisoner locked away in a dungeon.
It has no pain receptors, indisputably devoid of any sensation.
It has never felt warm sunlight or gentle breezes.
To the brain, the world is merely a stream of electrical signals, akin to a series of Morse code taps.
From neutral information, the brain creates a vibrant, three-dimensional, sensory-engaging universe for humans.
Your brain is you.
Everything else is just pipes and scaffolding.
"That’s not entirely true. Actually, brain science is indeed advancing rapidly; the basic operating principles of neurons are well understood, and how various neurotransmitters and neural signals are transmitted has been mostly figured out. Presently, the most difficult part in brain research is studying consciousness and cognition."
Liu Ziang said.
As one of the nation’s top brain experts, his words carry significant weight.
"That’s true. We currently know which part of the brain is responsible for major functions, how different parts work together when processing external information, the role of neurotransmitter hormones, and certain chemical actions during information processing."
"But on a deeper level, the biggest puzzle is how human consciousness is generated, what the molecular foundation of consciousness is, and what the principles and chemical processes that sustain consciousness are."
Zhao Heng also said with a sense of regret.
"Exactly, if consciousness can be expressed through matter, can matter control the generation of consciousness? If so, does it mean artificial matter could be made to create desired forms of consciousness? If such consciousness could be artificially created, then what are we? Also, the essence of emotions in the brain."
"The exploration progress of modern brain science in these areas is too slow."
Liu Ziang continued.
To understand his words simply, for instance, in the creation of steadfast belief, how does the brain operate internally? Does it secrete certain hormones and neurotransmitters, or do specific changes occur in the brain tissue?
If these material changes can be correlated with the formation of beliefs, then can it be said that scientists could artificially create belief?
Perhaps this is the nascent principle of a thought stamp?
Of course, thought stamps or whatever should be allowed to be researched.
If anyone really undertakes such research, that would be "criminal!"
"Research like interfering with consciousness through material means would not be allowed, even if someone proposes it. Let’s not think too far anymore."
Zhao Heng said.
"Dr. Zhao, Director Liu, the anesthesia is ready; you can start."
While Zhao Heng and Liu Ziang were engrossed in conversation, Tian Zhen glanced at the life monitor, noting heart rate, breathing, blood pressure, and carbon dioxide levels all had reached the standard for complete anesthesia, and then informed the two of them.
"Alright, senior, let’s proceed."
Upon hearing Tian Zhen’s words, Zhao Heng’s thoughts returned, and he nodded to Liu Ziang.
"Okay."
Liu Ziang also nodded.
The treatment route of this nanomedicine mainly includes three steps: the first step is intravenous injection of nanoparticles to accumulate at the tumor site; the second step utilizes imaging guidance and external stimuli for precise tumor treatment; the third step involves the external metabolism of the nanomaterials.
General nano treatments typically target only one of these steps without considering the others.
However, Zhao Heng’s treatment involves all three steps fully, requiring extremely high knowledge reserves and rich experience to achieve.
An hour later, Zhao Heng put down the instruments in his hands and breathed a long sigh of relief.
Though knowing beforehand that the risk of this nano surgery treatment was low, Zhao Heng still felt quite happy upon completing it.
Next, it’s just a matter of waiting to observe various metrics to see if this nano treatment was effective and how effective it was.
"Junior, I have several patients in my department with brain gliomas. If this treatment proves effective, I hope these patients can try this nano treatment too."
Liu Ziang fully supported Zhao Heng throughout the surgery, and it’s safe to say that Zhao Heng is the only one in Eastern Hospital who can have Liu Ziang cooperating in such an assistant-like manner.
"Okay."
Zhao Heng nodded, feeling the support from Liu Ziang.
With Liu Ziang’s status in the industry, having him as an assistant is quite valuable.
Not everyone can set aside their senior expert status to assist a mere resident doctor like Zhao Heng.
For instance, other experts at Eastern Hospital might approve of Zhao Heng’s skills professionally, but they may not necessarily be willing to assist him in surgeries.
"She can be sent back to the ward."
Zhao Heng said to Tian Zhen, who was standing by.
"Okay."
Tian Zhen nodded.
In no time, Ma Xiaochen lying on the transfer bed was sent out of the operating room, with Zhao Heng and Liu Ziang following suit.
Seeing her son lying on the transfer bed being pushed out, the anxiously waiting Liu Qing hurriedly stepped forward and asked Zhao Heng, "Dr. Zhao, how did the surgery go?"
"Very smoothly."
Zhao Heng replied briefly.
"Dr. Zhao, how significant is the impact of this surgery?"
Liu Qing asked again urgently.
"That will depend on the metrics three days later. If the treatment proves to be compatible, it can greatly alleviate the condition and sustain it until the siRNA colloidal bundle is developed."
Zhao Heng said.
"That’s good, that’s good, thank you, Dr. Zhao."
Repeatedly said Liu Qing. 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮
Regardless of her prominent status or the astounding wealth of the group she manages, right now she is just a mother worried about her son’s illness.
After exiting the operating room, Zhao Heng returned to the office to find it was already one in the afternoon.
Being a doctor is like this, often too busy to even eat a meal.
Zhao Heng wasn’t particularly hungry and took out some small bread from his desk drawer. After eating two pieces, Tian Zhen walked in and said to Zhao Heng, "Dr. Zhao, there’s a patient from the emergency department; you should go have a look."
"Now?"
Zhao Heng asked with some confusion.
"Yes."
Tian Zhen replied.
"Alright then."
Zhao Heng stuffed the remaining small bread into his mouth and stood up.
Just as he stepped out of the office, Zhao Heng heard an oppressive and pained roar coming from nearby.
Ah~
The sound was eerie and bone-chilling, just like something you’d hear in a horror movie.
