Chapter 261 [Delaying Pain] General Anesthesia, Local Anesthesia, Spinal Anesthesia!

Chapter 261 [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 it came time to get closer to the answer, Grete calmed down. The subsequent 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 fails, the experiment fails...

Grete calmed down and started tinkering with the scales, droppers, beakers and flasks. With Ren's liquid, weld the zinc sheet and the copper sheet together to make a zinc-copper bow. Well, it would be much more convenient with magic. You can directly burn them until they soften, directly join them together, and directly cool them down... Done!

Perfect!

Then, Grete began to make the frog, nail the wooden boards, smash the brain and spinal cord, cut off the upper half of the trunk... and complete the sciatic nerve-gastrocnemius muscle specimen. The laboratory was bloody, and the barbarians grimaced when they saw it. Only Gretel remained calm throughout, and even looked a little excited.

Just kidding, even if medical students are not like their colleagues in biology, they have dozens of frogs, mice, cats, dogs and various experimental animals that they have killed on their hands. Who would be afraid of such a scene!

From the beginning to the end, Gretel even maintained 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 flickers silently, falling quietly into the field of meditation.

What excites Grete 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 [Delaying 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, and calcium ions, amines such as 5-hydroxytryptamine, histamine, prostaglandins, etc. For example, a large proportion of dysmenorrhea is caused by prostaglandins. 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, transmitting 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?

Gretel decided to try it again. 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 range of the spell is a structure that is slightly like an hourglass shape. The two ends are not standard cones, but slightly twisted and coiled, with undulating patterns, a bit like ice cream on a cone.

This spell model is not too difficult for Gretel who has experienced in building a meditation shell. Isn’t it just distortion, isn’t it just pattern, everything is a mathematical problem!

After a series of calculations, building function models, and adjusting parameters, 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...

Grete took another frog, nailed it to the wooden board, and cut the skin of the leg with a knife. 【See through the invisible】! [Delay the pain], target, frog head!

In the meditation field of view, the fluctuations of the life aura in the frog's head decrease and ease, but the fluctuations in the legs are still strong. Is it that I can no longer feel the pain, but my limbs are still twitching spontaneously? It's a pity that he has never been able to learn the part of soothing animals in the divine art of Nature's Religion, and has no way to connect with the animals' perceptions. If only Pastor Matthew were here...

Gretel 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 in the head was still jumping. There was no way, Gretel used the traditional fixation method, and the frog had nails on its four feet, which hurt it.

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!

Grete kept up his efforts and continued to split the spell models. In this spell, the part that determines the nature of the spell is shaped like a flower. Under the flower, there are countless coiled roots. Grete tried to omit the roots 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. And omit the flower part, directly outline the roots, and cast the spell again——

Effective on the limbs, but not on the head!

interesting. Gretel's eyes sparkled and he recorded 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 and reducing the scope of the spell, the mana consumed by this magic has been 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 area, the lower the possibility of hitting. If there are multiple wounds on the body, it is even less practical - you can block it here, but you can't block it there...

But, medically, that would be 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, ah no, 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 they will definitely find opportunities!
