From small clinic to medical empire

Chapter 190
As the huge cement slab was slowly lifted, Durant immediately stepped forward to hug Chen Jian, and quickly ran towards the ambulance.

This is Zhang Zifan's explanation. Putting aside the conventional first aid guidelines, the first priority is to transport the patient to the [Life Ambulance] as quickly as possible.

As long as he gets on the life ambulance, Zhang Zifan can get at least 1 hour of limit blood lock time to find a way to treat the patient.

Durant's long legs showed a huge advantage among the steel and rubble, and it took less than 30 seconds to reach Chen Jianyun.

Lao Dao and others who had been waiting in the ambulance immediately started emergency treatment for the patient.

For example, cutting the fascia to reduce the pressure, such as using splints to fix the injured limb, such as further opening the vein channel.

During the whole process, the medical staff did not reset the fracture, do not wash or bandage the wound, nor did they raise the affected limb or perform local massage, so as to prevent myoglobin, potassium ions, and tissue toxins released from necrotic tissue from rapidly entering the blood circulation.

Next, is the most critical step, using a hemodialysis machine to dialyze the patient's blood.

The so-called hemodialysis, in simple terms, is to use a special filter membrane to purify the patient's blood.

Essentially, this is no different from the principle of a home water purifier.

Under normal circumstances, the kidneys of the human body perform this function. They can filter various toxins and metabolic wastes from the blood, and excrete them together with a certain proportion of water.

This process is urination.

However, patients with crush syndrome tend to have kidney failure and toxin levels in the blood soar. Therefore, extracorporeal dialysis must be used to help the kidneys purify the blood.

When Yang Fan was in the army, he was a nephrologist. Under his guidance, Shi Xiaoya chose a patient with an internal vascular fistula to establish a vascular access.

The blood enters the hemodialysis machine along the pipeline, is exchanged through the filter membrane, and then returns to the patient's body.

Shi Xiaoya looked at the monitoring data and said anxiously: "Dean, the filtration efficiency is insufficient! The patient's blood potassium level and creatinine are still rising!"

This is a very critical situation, which means that the existing dialysis capacity is not enough to reduce the concentration of harmful substances in the blood.

This is because although the patient's necrotic tissue has been partially removed, the remaining parts are still producing a large amount of toxins and entering the blood.

Just like the most boring elementary school math problem, pipe A drains water and pipe B drains water.

As long as pipe A is not as large as pipe B, the pool will be filled sooner or later.

The current situation in Chen Jian's body is like this, the speed of dialysis cannot keep up with the speed of accumulation of toxins, more toxins induce more cell apoptosis and produce more toxins.

It's a horrible vicious cycle.

Zhang Zifan's time is only one hour, he must find a way to break it!
……

"Hold on, don't give up hope!"

After Zhang Zifan confessed, he entered a state of contemplation with his eyes closed.

He opened the system inventory in his mind, and began to click on the [Mysterious Treasure Chest] one by one.

【Ding!Congratulations, you have obtained the blue item Sharp Scalpel × 1]

【Ding!Congratulations, you have obtained the blue item high-efficiency defibrillator × 1]

【Ding!Congratulations, you have obtained a purple item mid-level building upgrade coupon × 1]

……

Time passed by every minute and every second, like setting off fireworks, clusters of brilliance dispersed, and various good items appeared.

If it was normal, Zhang Zifan would be very happy. Among these items, there are many things that are very useful for hospital construction, such as the [Intermediate Building Upgrade Coupon], and there is even a rare piece of pink equipment.

But it is difficult to solve the fire near the water, these are not what Zhang Zifan needs.

Until the 206th minute of No. [-], all the [Mysterious Treasure Boxes] were opened. Things that Zhang Zifan hoped to find through opening the boxes, such as a super hemodialysis machine, never appeared.

Sure enough, the probability is too low!

Zhang Zifan shook his head, unable to hide his disappointment.

Medicine is a vast field, and it is tantamount to finding a needle in a haystack if you want to get the equipment related to hemodialysis. Unless the goddess of luck favors it, how can there be such a coincidence?

No matter what, I have done my best and have a clear conscience.

Just when Zhang Zifan was about to face reality, he suddenly set his sights on one of the objects.

This is the strongest prop produced in the 13 [Mysterious Treasure Chests] this time, and it is also the strongest prop that Zhang Zifan has obtained so far.

In terms of grade, it is higher than the previous two purple items [Life Ambulance] and [Hummer Medical Tank]. (In Chapter 173, there is an error in the level description of two items. They should be purple items instead of pink.)
That is the pink prop: [Kaleidoscopic Pupil Card]

……

The name of this item is unremarkable, and it is a one-time item. It does not seem to be worthy of the status of pink rare equipment.

But in fact, if you read its description carefully, you can know how powerful it is.

[Kaleidoscopic pupil technique card: The user can evolve a certain pupil technique to obtain a more comprehensive and powerful pupil technique.

ps: You don't need to lose your loved ones to experience a more powerful pupil technique, so why not hesitate, experience it now! 】

……

Previously, Zhang Zifan had always limited his thoughts to practical items that could have immediate effects, subconsciously ignoring them.

Thinking about it now, this powerful prop might be the key to breaking the deadlock.

After all, the description of this equipment is very reasonable. Anyway, there are no side effects, so there is no loss in trying it!
Zhang Zifan currently has 3 types of pupil techniques.

[The Eye of Preset]: Finding and innovating surgical methods through presetting surgical methods is a big killer in clinical practice.

[Eye of Pain]: By causing a certain non-fatal disease in the patient in advance, it makes him feel pain. At present, it is too useful for sand sculptures, and Zhang Zifan seldom uses it.

【Eye of deconstruction】: From the cellular level to the molecular level, deconstructing the target is a good hand in scientific research.

[Kaleidoscopic pupil technique card] There is only one card, so which kind of pupil technique is more suitable to improve?

After a short thought, Zhang Zifan finally chose the third pupil technique [Eye of Deconstruction].

This is because, at present, Chen Jian's condition cannot be solved by surgery at the macro level.

Zhang Zifan reckoned that the ability obtained by evolving the [Eye of Preset] is less likely to resolve the crisis.

Relatively speaking, [Eye of Deconstruction] mainly deals with problems at the micro level. Whether it is dealing with current problems or long-term basic medical research, if you choose to evolve it, you will gain more benefits.

As for [Eye of Pain], Zhang Zifan is completely unaware of its role. If it evolves, it only has multiple analgesic abilities, and it would be too foolish.

Zhang Zifan has already used [Eye of Pain] to cheat his own father once, and he doesn't want to cheat a second time.

After simple consideration, Zhang Zifan found that he had nothing to hesitate no matter whether he was benefiting others or himself.

Therefore, he immediately clicked on the [Kaleidoscopic Pupil Card] and chose to strengthen the [Eye of Deconstruction].

……

With a burning pain in both eyes, when Zhang Zifan opened his eyes again, the original [Eye of Deconstruction] column in his skill column changed.

[Eye of Deconstruction/Reconstruction: This skill has two modes.

Using the Eyes of Deconstruction, organisms can be deconstructed from the cellular level to the molecular level.

Using the reconstructed eye, a new biological model can be constructed based on the biomechanical principles of the deconstructed materials.

ps: Deconstruction and reconstruction still follow the second law of thermodynamics, that is, the law of entropy increase. 】

Looking at the new skill description, Zhang Zifan frowned.

It's not that the compound pupil technique evolved this time is not powerful, but it still doesn't seem to be able to solve its own problems.

Zhang Zifan originally guessed that he might be able to obtain unlimited deconstruction, or super deconstruction ability.

In this way, he might be able to transform into a super human flesh dialysis machine and deconstruct all the toxins in Chen Jian's body.

But obviously, such a situation did not occur.

Something as unscientific as a system, yet it follows the laws of science so rigidly in its actual operation.

Zhang Zifan's ability in deconstruction has not improved at all!
Not to mention that according to the second law of thermodynamics, Zhang Zifan would need a huge amount of energy to deconstruct all the harmful substances in the patient's blood.

Whether the speed of deconstruction alone can keep up with the production of new toxins is also a huge question.

But on the other hand, although the ability to deconstruct has not been improved at all, I have an additional ability to reconstruct.

So what role does this reconstruction ability play?

Suddenly, Zhang Zifan saw the hemodialysis machine operating at full capacity, and suddenly thought that if he jumped out of the original thinking pattern of relying on hemodialysis, the reconstruction ability might be able to find another way, and there is a lot to do!
……

The so-called dialysis, what most people think of is hemodialysis technology.

But in fact, the commonly used clinical dialysis technique is not only extracorporeal hemodialysis, but also a widely used dialysis method called peritoneal dialysis.

Peritoneal dialysis does not establish extracorporeal blood circulation, but uses the method of perfusing peritoneal dialysis fluid, uses the human body's own natural peritoneum as a semipermeable membrane, and uses the principles of osmotic pressure and molecular diffusion to remove metabolites and toxic substances in the body and correct water loss. , Electrolyte balance disorder purpose.

Compared with hemodialysis, peritoneal dialysis is simple, cheap, convenient, safe, does not cause cross-infection, does not cause fluctuations in blood pressure, has little impact on the natural blood circulation of the human body, and is conducive to preserving the remaining kidney function.

It can be said that compared with hemodialysis, peritoneal dialysis has almost endless advantages.

But it has a shortcoming, and only this one shortcoming is that peritoneal dialysis is overwhelmed by hemodialysis, and it is always in a marginal position.

That is the inefficiency of dialysis!

Specifically, the peritoneum, despite its large size, is not itself an organ used to form urine.

Using peritoneal dialysis technology, the ability to remove large molecules and middle molecules in the blood is still good, but for small molecules with smaller diameters and inorganic substances like potassium ions, the ability to remove them can only be described as weak.

A kind of medicine, no matter how small and safe your side effects are, if your curative effect is poor, it will be finished. At most, it can only be used as an adjuvant medicine for mild patients, and it will never be able to support the big table.

Peritoneal dialysis is in such an awkward position.

What's more troublesome is that because the peritoneum is not in its position but seeks its own affairs, it will cause irreversible damage in the long run, and eventually lose the function of the semi-permeable membrane.

Although the shortcomings are huge, it is undeniable that biofilms, especially the human body's own biofilm dialysis, have unique advantages over synthetic materials such as polyacrylonitrile membranes, polysulfone membranes, and cellulose acetate membranes.

If we find a way to strengthen the peritoneum to some extent, or find a more reliable and efficient biomembrane, then dialysis technology will become more comprehensive, safer and more efficient.

Thinking of this, Zhang Zifan looked at the time on the electronic screen, and it was exactly 30 minutes since Chen Jian was carried into the car.

I can't wait!

"Tranquility, go and call Deputy Kong over."

Zhang Zifan stood up and gave orders, and then said to Yuan Qiang and Zhu Jiannan: "Prepare for laparotomy immediately. I will try a new dialysis method. It must be completed within 20 minutes. Everyone must obey the command. If you have any questions, please go to the surgery department." Discuss later!"
