Chapter 1814 Is there water in your brain? Watch me drain it out with my magic!
Gretel's research on craniocerebral blood pressure reduction is progressing in parallel in several aspects.
It didn't go well in several aspects.
In terms of medicine, the only thing he could get by tiptoeing was kelp extract-mannitol. The problem was that he couldn't handle this thing alone. He could 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 college, and thanks to "Organic Chemistry", the molecular formula and chemical structure of mannitol are written on it, allowing Gretel to have a targeted target when launching the [Limited Wishing Technique].
With a flash of light, the kelp turned into ashes and disappeared, and a piece of white crystal powder fell into the beaker prepared by Gretel:
Next is the work of the alchemists. They have to analyze the properties of this stuff, and then use various methods to extract a large amount of mannitol from the kelp:
The cost must be low, the output must be large, and most importantly, the purity must be high enough. It must be high enough to 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 always not 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 can only do whatever they want. In addition to manufacturing and purifying, he still has a lot of other research to do:
For example, what should be used to mix mannitol injection with mannitol? Distilled water? Normal saline? Glucose water?
Forgive his basic theory of medicine and pharmacy. Basically, the basic theory of medicine has been returned 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? For intravenous infusion, how fast should the infusion be? What should be paid attention to during use, and under what circumstances should the drug be stopped immediately?
By the way - it is easy to eliminate the effects of drugs. As long as mannitol is defined as a "toxin" and a detoxification technique is used, it can be eliminated in an instant...
Even with such direction guidance, Grete still has a lot of things to study in the direction of drugs. Without thorough research, he will never dare to use it on people.
In terms of surgical blood pressure reduction, it is even worse:
The four major surgical punctures are chest puncture, abdominal puncture, bone puncture and lumbar puncture. Even though this is a required question in the examination for practicing physicians, how many practicing physicians have passed the exam and trembled in fear when facing patients, not daring to do it.
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...
Either way, the difficulty is sky-high. A method for measuring intracranial pressure has been developed. Based on 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 operate. Of course, given the fierceness of the local spellcasters, they would really dare to open the skull if pressed, especially the necromancers.
The problem is that even if there are sufficient disinfection measures and therapeutic techniques to protect the brain, the mortality rate of craniotomy and decompression is still hard to explain:
If the pressure is decompressed too quickly, the brain tissue will be damaged and the probability of collapse will be too high. If it collapses, collapse, collapse... the brain will die!
Poor Gretel, 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 he didn't understand in the past can only be replenished with tears. While Grete worked 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 brain 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?
For example, reduce tissue fluid by one percent?
"Or one percent of the cerebrospinal fluid will do! When the cerebrospinal fluid is reduced, the fluid in the cells and the tissue fluid will leak water into the cerebrospinal fluid, which can also reduce intracranial pressure!
Isn’t there any result in the Conjuration Department? Not in the Necromancy Department either? [Touch of Thirst] is a spell from your Necromancy Department! It’s a small first-level spell, and you still haven’t figured it 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. Only then can you create countless tricks on your hands...
However, basic research is always the most difficult. No matter how much Gretel pressed and pressed, the necromancy and conjuration systems, after half a month and a month of hard work, still had no results.
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 skulls 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...
