Chapter 1821 Are You Out of Your Mind? Watch Me Drain It with My Magic!

Gretel's research on cranial blood pressure has gone hand in hand in several aspects.

Not going well in several ways.

In terms of medicine, the only thing he could get on tiptoe was kelp extract-mannitol. The problem is that he cannot handle this thing alone. He can only keep urging the alchemist:

"How about it?"

"Has it been extracted?"

"When can it be extracted?"

"Haven't all the samples been given to you?"

Yes, samples are still easy to find. Gretel got a large bundle of kelp, burned a diamond, and activated the limited wish spell:

"I need an extract called mannitol, which is a natural alcohol that is abundant in kelp... Its chemical formula is C6H14O6, and its molecular formula is..."

Thanks to the basic courses in the university and "Organic Chemistry", which contained the molecular formula and chemical structure of mannitol, Gretel could use the [Limited Wishing Technique] in a targeted manner.

With a flash of light, the kelp turned into ashes and disappeared. A piece of white crystal powder fell into the beaker prepared by Gretel:

Next is the work of the alchemists. They want to analyze the properties of this stuff, and then use various methods to extract a large amount of mannitol from kelp:

The cost must be low, the output must be large, and most importantly, the purity must be high enough. It is so high that it can be made into an injection and intravenously dripped without causing side effects...

"It can't be purified!"

"Yes, no matter how hard you try, the purity is never enough... You must use the original sample as the basis and use the magic circle to purify it..."

"Actually, this is not a bad thing... With the original sample in our hands, we no longer have to worry about others taking away our business..."

Gretel could only do as they pleased. In addition to manufacturing and purification, he has a lot of other research to do:

For example, for mannitol injection, what should be used to mix the mannitol? Distilled water? Normal saline? Glucose water?

Forgive him for basically returning the basic theories of medicine and pharmacy to the teacher. To answer this question, we must start from scratch...

For another example, what is the concentration of mannitol injection? 5%? 10%? 20%?

What is the dosage? If intravenous infusion, how fast should the infusion be? What should you pay attention to during use, and under what circumstances should you stop taking it immediately?

By the way - it is easy to eliminate the effects of drugs. As long as mannitol is defined as a "toxin", it can be eliminated instantly with a detoxification spell...

Even with such direction guidance, Grete still has a lot of things to study in the direction of drugs. If you don't study it thoroughly, you will never dare to use it on people.

In terms of surgical blood pressure reduction, it is even worse:

The four major surgical punctures, chest puncture, abdominal puncture, bone puncture and lumbar puncture, are not required in the examination for practicing doctors. How many practicing doctors have passed the examination, but they tremble in front of patients and dare not start.

As for reducing intracranial pressure, there are only two surgical methods: the simpler one is lumbar puncture and then placing a drainage tube; the more difficult one is to directly open the braincase, drill holes for drainage, or craniectomy to decompress...

No matter which one, the difficulty is sky high. A method for measuring intracranial pressure has been developed. On the basis of blood pressure measurement, the spell model has been modified, and the spell can be used directly for non-invasive measurement:

Compared with the previous method of doing a lumbar puncture and then measuring the cerebrospinal fluid pressure, it is much more convenient and safer, and the patient suffers much less.

However, being able to measure does not mean being able to perform surgery. Of course, with the fierceness of the local spellcasters, they would really dare to open their heads if pressed hard, especially the necromancers.

The problem is that even with adequate disinfection measures and therapeutic techniques to protect the brain, the mortality rate of craniotomy and decompression is still hard to describe:

If the pressure is decompressed too quickly, the probability of brain tissue damage and collapse is too high. If it collapses... the brain will die!

Poor Grete, although he was the deputy chief physician of the emergency department in his previous life, he was really not good at brain surgery. When encountering a head injury or suspected brain injury, in addition to saving the patient's life, he would definitely call for help as soon as possible:

This thing is so professional!

Brother, come on!

The knowledge that I didn’t understand in the past can only be replenished with tears now. While Grete was working hard to read books and papers, under the protection of healing techniques, he joined forces with the necromancers to explore the methods and rules of craniotomy and decompression.

Of course, the skull cannot be opened if it can be opened, and the surgical trauma can be reduced as much as possible. Gretel's greatest hope is still in the group of spell decompression:

【Touch of Thirst】!

When will the dismantling of the spell model be completed?

When can we determine which part of this spell model is responsible for spell range and spell power——

When can this spell be made sensitive enough to reduce a certain part of the liquid in a targeted manner according to the needs of the caster?

Like, reducing tissue fluid by one percent?

"Or one percent of the cerebrospinal fluid will do! When the cerebrospinal fluid decreases, the fluid in the cells and tissue fluid will leak water into the cerebrospinal fluid, which can also reduce intracranial pressure!

Isn’t the Conjuration System still fruitful? Not even the necromancy system? [Touch of Thirst] is your necromancy spell! A small first-level spell that you haven't figured out yet? ! "

...Boss, you are also an eighteenth-level mage yourself, but you have not broken down and understood "a small first-level spell"...

The conjuration system dared not speak out... The necromancers, facing the Plague Lord's accusations, bowed their heads to the dark wall one by one...

So this is the research method of the Plague Lord? Each spell must be broken down into small pieces and understood clearly, and only then can there be countless tricks on his hands...

However, basic research is always the most difficult. No matter how Gretel pressed and pressed, after half a month and a month of tossing about the necromancy system and the conjuration system, there was still no result.

On the other side, His Excellency Rimmer, the Grand Duke of the Vampire Race, came up with something interesting:

"Cerebrospinal fluid?" Grand Duke Rimmer opened the brains of seven or eight rabbits in succession and performed seven or eight lumbar punctures. The red light in his eyes became darker and brighter:

"What an interesting thing... very fascinating... the brain is actually connected to the spinal cord in this way... In this case, I can control the casting range of [Thirst Touch] and focus it on the cerebrospinal fluid, okay? ?”

brush!

Well, the spinal cord was too damaged, the entire spinal cord collapsed, and the rabbit was paralyzed...

brush!

Another paralyzed one...

brush! brush! brush!

Spicy Rabbit Head, Hot Rabbit Head, etc. are all gone...
