It's not that difficult to open a hospital in another world, right? Chapter 257 [Delaying Pain]——General anesthesia, local anesthesia, spinal anesthesia!
Chapter 257 [Delaying Pain]——General anesthesia, local anesthesia, spinal anesthesia!
Known: [See through invisibility] You can see the life aura of living things.
Asking: What is the aura of life?
When he got close to the answer, Gretel calmed down. The next verification work requires sufficiently detailed preconditions - even when the preconditions are complete, there are still many students who are just getting started, and the experiment fails.
, the experiment failed...
Gretel calmed down and started tinkering with scales, droppers, beakers and flasks. He mixed Ren's solution and welded the zinc and copper pieces together to make a zinc-copper bow. Well, it would be much more convenient with magic. It can be burned directly.
Soften, join them directly together, cool directly...done!
Perfect!
Then, Grete began to make the frog, nailing the wooden boards, destroying the brain and spinal cord, cutting off the upper half of the trunk... and completing the sciatic nerve-gastrocnemius muscle specimen. The laboratory was bloody, and the barbarians grimaced when they saw it. Only Grete kept it, from beginning to end.
His expression remained unchanged, and he even looked a little excited.
Just kidding, even if medical students are not like their colleagues in biology, they have dozens of dried frogs, mice, cats, dogs and various experimental animals on their hands. Who would be afraid of such a scene!
From the beginning to the end, Grete even maintained his meditation and did not leave the state due to emotional fluctuations. The frog in his hand, shrouded by [See Through Invisibility], the aura of life flickered silently and fell quietly into the field of vision of meditation.
What excites Gretel is that even with only a fragment of the spine and frog legs left, a faint aura of life can still be seen in the vision of meditation.
So……
Zinc and copper bow, dipped in Ren's liquid, stimulate the sciatic nerve!
The moment the two ends of the metal piece touched each other, the frog's gastrocnemius muscle contracted violently. At the same moment, the brightness of the aura of life in Grete's meditation field of vision jumped up significantly!
That’s right!
[See Through Invisibility] With this magic, the aura you see is most likely bioelectrical fluctuations!
So……
What is the mechanism of action of [Delay Pain]?
Grete recalled the contents of the "Physiology" textbook. The principle of human body feeling pain is divided into three steps:
When the body is injured or inflammation occurs, the damaged cells release pain-causing substances, such as inorganic salts of potassium, hydrogen, calcium ions, amines such as 5-hydroxytryptamine, histamine, prostaglandins, etc. For example, a large proportion of dysmenorrhea is caused by
Prostaglandins cause trouble. Taking ibuprofen in advance can inhibit the production of prostaglandins and achieve analgesic effect;
Nerve endings are activated by exogenous pain-causing substances or endogenous pain-causing substances, generating receptor potentials, which in turn trigger transmissible action potentials and transmit injury information along the nerves to the brain. It can be seen that this process is
Bioelectricity at work;
The cerebral cortex integrates the pain information, and finally, the human body feels the signal of "pain"——
So, [delaying pain], at which step in this process does it work?
Grete decided to do another experiment. This time, he followed Mrs. Seat's teachings and narrowed the scope of [Delaying Pain], narrowed it, and narrowed it again.
In the spell model of [Delay Pain], what determines the coverage area of the spell is a structure that is slightly like an hourglass. The two ends are not standard cones, but are slightly twisted and coiled with undulating patterns, a bit like the top of a cone.
Same as ice cream.
This kind of spell model is not too difficult for Grete, who has experienced it when building a meditation shell. Isn't it just a distortion, isn't it just a pattern? Everything is a mathematical problem!
After a series of calculations, building a function model, adjusting parameters, and a series of steps, he was able to reduce the scope of magic from covering the entire human body to the size of a bowl.
If we want to shrink again, it's not that the parameters can't be adjusted, but that Gretel's mental power and spell control ability can't support it anymore...
Gretel took another frog, nailed it to the wooden board, and cut the skin of the leg with a knife. [See through invisibility]! [Delay pain], target, the frog's head!
In the meditation field of vision, the fluctuations of the life aura on the frog's head are reduced and softened, while the fluctuations in the legs are still strong. Is it possible that the pain is no longer felt, but the limbs are still twitching spontaneously? What a pity, in the magic of the Natural God Sect, comfort is
He has never been able to learn the animal part, and has no way to connect with the animal's perception. It would be great if Pastor Matthew was here...
Grete thought for a while, canceled the spell, and threw the second [Delay Pain] to the frog's leg. This time, in the meditation field of vision, the fluctuations of the life aura in the frog's legs calmed down, but the aura on the head was still jumping. Nothing.
As for the method, Grete used the traditional fixation method, with nails nailed on the frog's four feet, which caused pain.
Well, that is to say, the [Delay Pain] spell can at least suppress the bioelectrical conduction of part of the pain nerves within the range covered by the spell...
So, if what is suppressed is the nerve, is it possible that after the nerve response is cut off, the pain sensation in the terminal limbs will no longer be transmitted to the brain?
Grete impulsively threw a spell on his thigh. Then he leaned down and pinched his calf hard.
It really doesn’t hurt!
Gretel continued to work hard and continued to split the spell model. In this spell, the part that determines the nature of the spell is shaped like a flower. Under the flower are countless coiled roots. Gretel tried to omit the root part and cast the spell again...
The frog struggled violently. However, when the spell was thrown to the frog's head, the frog immediately calmed down, and the life aura on the head also became gentle, and the fluctuations were no longer violent. Omit the flower part, directly outline the roots, and cast the spell again
——
Effective for the limbs, but not effective for the head!
It’s interesting. Grete’s eyes are shining and he records quickly, so the “flower” part is the control center, preventing the brain from recognizing pain; and the “root” part is the sensory nerve, suppressing bioelectrical conduction?
This mechanism is very interesting!
Moreover, after splitting, the scope of the spell's coverage is reduced, and the mana consumed by this magic is directly reduced from the second-level magic to the first-level magic. Such changes are of course not very useful in combat. The smaller the coverage, the harder it is to hit.
The lower the possibility, the less practical it is if there are multiple wounds on the body - you can block it here, but you can't block it there...
But, in medical terms, it is so useful!
Local anesthesia!
Why do you need general anesthesia when you can have local anesthesia?
If you can have spinal anesthesia, there is no need for general anesthesia!
It's a waste of anesthetics, no, it's a waste of mana, and it also affects the patient's recovery!
Tomorrow, just tomorrow, go to the treatment center and give it a try! If there are no suitable patients in the treatment center, you can also go to the dock or the fleet. The porters and soldiers there have many daily encounters, and you will definitely find opportunities!
