Chapter 1338 Little Grete, why are you involved in necromancy again?
Using magic to replenish fluids - if possible - does have advantages over using water to replenish fluids.
Gretel spread out the manuscript paper and thought about it while making plans. After all, blood grafting is an invasive operation. Even if the patient's pain is not taken into account, there are still problems such as unnecessary needles and blood coagulation.
Vascular injuries, vascular fistulas, bacterial infections, central venous catheterization with heparin, etc., everything is a challenge——
If you can use magic to send liquid directly to the patient's veins, it is better than having to poke a hole in the blood vessel.
The value of developing this spell is very high!
"So on which magic basis should we change it?"
Gretel browsed through the magic he knew and the magic list one by one. Take a deep breath? The one that fills the lungs with gas instead of filling the blood vessels with liquid?
Detoxification? A reverse version, injecting potassium ions or something into the blood vessels, instead of injecting a large amount of liquid?
Blood boiling technique? The one that heats the enemy's blood? Although it may not be easy to use, but it can accurately raise the added liquid to 37 degrees, which is very powerful...
Gretel was writing and drawing, selecting one, denying one, selecting another, and denying another. He scrolled through the fifth-ring spells until he found one that seemed to have great potential:
"[thalassemia]?" Elder Fahim who came to see him choked and tried not to frown:
"Little Grete, this is a necromancy spell. Have you...have you learned it?"
Thalassemia, this magic can make the blood of living creatures it touches become almost as thin as sea water, causing heavy damage.
Grete guessed that its principle might be to extract blood cells, or it might be to replace blood - if it can be extracted, it can be filled, if it can be replaced, of course it can also be filled!
"I haven't learned anything." Gretel replied confidently:
"But I can get the spell configuration. Once I get it, it shouldn't be difficult to dismantle, analyze, and modify it, right?"
After all, he has even dismantled the eighth-level [Clone Technique], and the fifth-level [thalassemia] cannot be more difficult, right?
Gretel communicated with Nevis, and as expected, he got the spell configuration and detailed analysis of [Talassemia], and then he plunged into the research.
Of course, the daily sampling of chromosomes still needs to be taken, and the daily calculations of moving the tower spirit and the oak staff cannot be left behind. However, this does not prevent him from doing the calculations by hand, right?
Well, this configuration is used to lock the target of the spell. Although it relies on touch guidance, the scope is all over the body of the caster. Let's see if it can be narrowed down to a certain vein;
Is this configuration used...is it really used to replace blood? Take it apart again and see how to change the replacement to injection and how to lock the injected liquid;
Injection speed... The Thalassemia spell is injected in an instant. We need to see how to adjust it...
Grete buried himself in the study, spending more than a month just splitting, modifying, and reconstructing. And the final result was a batch of different versions of spells:
"Come on, get on the rabbit!"
"I'm going to fuck the rabbit again..."
The elves working in the laboratory wailed. The healers who were temporarily transferred back from the front battlefield to watch the experiment also showed unbearable expressions.
However, this time, no one protested to Gretel or shouted "Why use rabbits?":
The lesson learned by Kusa Oak when he developed blood-replenishing magic was really painful and profound.
They obediently took out the rabbits from the rabbit cage. There were ten adult male and female rabbits of each type. They weighed them, checked their vital signs, and drew 20 ml to 50 ml of blood.
Hang up the monitor, pay close attention to heart rate, blood pressure, breathing and life breath intensity, and take rehydration magic:
【thalassemia·modification】!
Grete held a small bottle in his left hand, filled with 50 ml of Ringer's solution, and the temperature was adjusted to 8 degrees - exactly the normal body temperature range of rabbits;
The light of the spell on his right hand shone brightly and was photographed on the rabbit that had been drained of 50 ml of blood. The Ringer's solution in the bottle was swept away, and the liquid was automatically injected into the rabbit's blood vessels under the action of the spell——
Almost in the blink of an eye, the light pillar representing the breath of life fell directly from the unstable deep yellow to the deep red and black position.
And the monitoring magic set up by Gretel also issued a warning frantically:
"This rabbit is dying!"
"Heart rate 350! 402! 438!"
"Respiratory rate……"
"blood pressure……"
"It's vomiting blood! It's vomiting blood! - No, it's not vomiting blood, it's vomiting pink foam..."
"It's dying!!!"
Look, injecting too much at once won’t work. Gretel shook his head regretfully and crossed out the first version of the rehydration magic:
"Everyone has clearly seen that it is impossible to replenish a large amount of fluid in one minute, or even one second. Losing a lot of blood will make the heart already weak, but if you have to pump out so much fluid, the heart will be exhausted!"
The elf healers who were transferred back from the battlefield and shouted, "How much blood has been shed, can't we just pat it in all at once?" were speechless when faced with the rabbit that died on the spot.
Grete looked around them. He had expected this result, but he could only speculate based on the principle——
In the past life, no one had done such an experiment. Whether it was a venous channel or a bone marrow cavity, it was impossible to pour several liters of liquid into the human body in one second.
However, facing the dead rabbit, he still sighed:
"Also, if the heart cannot pump blood, excess fluid will seep into the alveoli, causing pulmonary edema or even pulmonary hydrops. Once the heart and lung functions collapse, the entire body will be ruined!
In hemorrhagic shock, when giving large amounts of fluids, be sure to pay attention to the possibility of heart failure and pulmonary edema!"
This time, the elf healers in front of Gretel all nodded their heads.
If instantaneous infusion is not possible, it can only be infused slowly. In Grete's previous life, there was no problem in injecting 2000 ml of liquid within one hour, but the patient's condition needs to be paid close attention to;
When there is a serious hemorrhage, the blood flows like a waterfall on the operating table. Blood transfusions are performed at the same time as the operation, the bone marrow cavity is opened, and 5,000 ml of fluid is pumped in an hour, and it can still be done.
Of course, subsequent DIC (disseminated intravascular coagulation) and other blood transfusion complications will be considered later.
After all, if you don’t transfuse blood, you are not even qualified to consider it...
Grete would input 5000 ml of liquid per hour, then 2000 ml per hour, and adjusted this magic to more than a dozen different speed versions.
Add an adaptive function - the liquid cannot be filled all the time until the rabbit or the subject explodes, and you have to know when to stop - and then send it to the researchers under your command:
"Fifty rabbits per person! Blood loss is 10%, 15%, 20%, 30%, all the way to 50%. Try them all to see which version works best and which version is safe!"
