Chapter 1823 What Does Lumbar Puncture Do to You Spellcasters!

It's impossible to smoke more than once, absolutely impossible.

For an experiment, repeated lumbar punctures may be performed on rabbits, maybe dozens, hundreds or even hundreds of times... Grete said that it does not exist, absolutely does not exist.

He is already very familiar with waist piercing and other things, and there is no need to practice using this method! On the contrary, his healers need more practice...

"Teacher, is this...the needle inserted like this?" Annevia pressed the rabbit with one hand and held the puncture needle with the other, her cheeks tensed. Grete nodded calmly:

"Yes, that's it. First, bend the rabbit's body as much as possible. If it is a human, it needs to lie on the left side, with both hands on the knees... to make the lumbar spine kyphosis and widen the intervertebral space..."

"Teacher, can I put a [Detection Magic]? Or use mental power to observe?"

Gretel: "..."

Lumbar puncture under X-ray guidance? Or use mental power to observe the position of the bones and then insert the needle? Make sure you don't insert the needle skewed and don't insert it too deep?

Alas, the conditions for today's children to practice medical skills are really good... When he was studying medicine, he would have just started inserting needles into any patient under the guidance of X-ray, fearing that the teacher would break his head - —

Do you want to put patients on the line for no reason?

How many more threads do you want to eat yourself?

Practice, go back and practice with a dummy, don’t start if you’re not familiar with it!

I am really happy now. With the guidance of [Detection Magic] (x-ray), at least the needle will not go astray, tilt to the left, tilt to the right, hit the bone, and the tip of the needle will be crooked——

It is common for the tip of a needle to break. Newbies who have just entered the industry are timid. If they find that the needle cannot penetrate, they will generally not use all their strength recklessly.

However, deviation of the puncture position, improper puncture direction, too shallow or too deep puncture will lead to puncture failure. Especially when piercing a child, the child is frightened, crying, and uncooperative. The position and direction of the piercing often become distorted after a little struggle;

There is also the piercing of a fat man, which also makes people very desperate.

Grete heard a case shared by a teacher in our hospital. In the past three years in the hospital, six obese patients failed to undergo lumbar puncture - all of them were fat people with a BMI of 40 or above - because they were too fat and could not feel the location of the bones. No depth...

In these six patients, puncture failed 19 times in total. Finally, 4 cases were successfully punctured under X-ray fluoroscopy, and 2 cases were successfully punctured under CT guidance.

The teacher also published a paper specifically for this purpose to tell the newcomers that if it doesn’t work, we shouldn’t insist on it. If we encounter such a fat person, if we can use fluoroscopy guidance, let’s use fluoroscopy guidance...

cough.

After sighing with emotion about his struggles back then, Gretel became kind and cheerful when faced with the students' demands:

“You can still use it if you’re just starting to learn and if you’re not skilled with your hands. However, you should try your best to practice until you can locate it by looking with your eyes and touching it with your hands.

The person you are going to treat in the future may be of a very high level and you will not be able to find the magic light source in time; it may also be that your mental power is running rampant and your mental power cannot detect it..."

"Yes, teacher! I remember it! I will try my best to be able to locate it with my eyes!"

"Very good, come on, disinfect, pat [Delay Pain] - this is used for surface anesthesia, so that the patient will not struggle due to pain - then, position, level the puncture needle, and insert the needle! Very good!

Insert the needle slowly and feel it with your hand... Which ligaments should the needle pass before moving forward and entering the subarachnoid space? "

"Supraspinal ligament, interspinous ligament, ligamentum flavum!"

Very good, Anivea's basic skills are quite solid, and when faced with such an unexpected question, she answered it word for word. Grete nodded with satisfaction:

"Yes, the needle tip penetrates the triple ligament and when it enters the subarachnoid space, you will feel the resistance suddenly disappear. Just like when you use an awl to pierce cowhide, there is a sense of breakthrough——

Remember this feeling. If you feel a breakthrough, stop the injection immediately, otherwise the spinal cord will be damaged! "

He taught his disciples here, surrounded by a group of necromancers and nature priests, eagerly watching and memorizing. It's a pity that Gretel taught his disciples that outsiders like them are not worthy of asking for advice without permission——

Unexpectedly, Gretel suddenly turned his head:

"Did you all remember what I just said? You also need to be able to do these operations! - What do you want me to do? Lumbar puncture is a basic medical operation. If you don't learn it one by one, you still expect me to do it myself every time?! "

"Ah, yes! Yes!"

The healers responded with a roar. Immediately, parchments, quills, and record books were flying all over the sky, making a rustling sound:

Write it down quickly!

Write down every word!

I wrote it down, we will practice with rabbits in the future too! Practice with pigs! Practice with various monsters!

"By the way, no one is allowed to practice without my permission! If you don't tie it properly, your spinal cord will be damaged!!!"

Gretel suddenly turned his head and spoke with a warning. The faces of the Nature Priests and Conjuration Healers tightened, but only the Necromancer remained proud:

Not allowed to use people to practice?

That's easy, as long as you are allowed to practice with corpses!

Our necromancy department lacks everything except corpses! Brothers over there, do you want to come over to our place and borrow two corpses to practice?

Hey, speaking of it, if the corpse with spinal cord injury is used to evoke the undead, I wonder if the effect will be worse... If you can't test it with [Evoking the Undead], then you can only dissect it...

Gretel saw all their eyebrows and lawsuits, and decided to pretend not to see it - he was such an adult, it was time for him to have some subjective initiative.

He just taught Anivea:

"Come on, insert the needle, insert the needle...do you feel a breakthrough? Very good, stop! Now pull out the needle core. There will be colorless and transparent liquid dripping out of the end of the needle. This is very good. The puncture was successful..."

"Teacher, can I use vines or hollow thorns to pierce it?"

Anivea suddenly asked. It is too expensive to use this kind of steel needle. Let an alchemist make it, and it is easy to get a price that a patient cannot afford...

It's better to use vines or thorns. They can be used to spawn as you use them, and they can be dispelled when they are no longer needed. It’s cheap, clean, and doesn’t even require disinfection——

How wonderful!

"Ah, you can try it." Gretel tried his best to keep his face from becoming stiff:

"First of all, the vines or thorns you use must be thin enough, with a minimum diameter of 0.7 mm and a maximum thickness of only about 1.5 mm. Secondly, the strength must be high enough to break through the three layers of ligaments and penetrate the dura mater. Thirdly, it can Give you feedback..."

"I can give you feedback! The vines and thorns I spawn are just like my fingertips!" Anivea replied immediately:

"Diameter...strength...I'll give it a try..."

"Go and give it a try! Don't be anxious, as I said before, experiment on animals first!"

Fat people really have a lot of extra troubles with medical treatment... If you can lose weight, well, try to lose weight...
