Chapter 1337 Relying on infusion to rescue? We can’t learn this, Teacher Grete!
Use magic to rehydrate...
This idea is theoretically feasible. Gretel has used [Detoxification Technique] before to instantly drain the potassium chloride from the heart of the target, or to instantly infuse a large amount of potassium chloride...
Starting from here, it is not impossible to use magic to pour Ringer's solution into the blood vessels. However, the specific magic to be used needs to be carefully studied.
Gretel suppressed his thoughts and kept his hands and feet focused on the injured soldiers.
After Bernard, other soldiers were sent down one after another. Gretel straightened the bones one by one, connected muscles and tendons, replenished fluids, and applied blood-replenishing magic...
He used an ancient tree with attack, defense, and concealment functions as an infusion stand. Countless branches stretched out from it, as if bearing fruit, and a row of infusion bottles were hung on it.
——If Gretel hadn't developed the function of rapid oxygen supply, I'm afraid I would still have to train the ancient trees and stuff two leaves into each of these elves' noses so that the warriors who need it can breathe oxygen for a while...
In short, while the healers at the front were flying across the battle line, fighting and treating the soldiers, Gretel was in the middle and rear, running around without even touching the ground.
He walked down the ancient tree like a butterfly through flowers. He alone exerted the functions of nearly ten healers...
"Everyone lie down! Lie down! Don't move!"
"Don't move your hands! Pay attention to the needle! - Oops, the blood has returned again! If you move any more, I will let the ancient tree tie you up!"
"CPR!"
"Defibrillation!"
"Ashu, don't stop the group healing! Hold the blood line! Hold it!"
"Serila, go get another bottle of water for No. 3! Pay attention to how many bottles he has hung up!"
It was not until the battle was over that the healers on the front line returned to the ancient trees one after another, and only then were the wounded taken over.
Grete wiped his sweat, sat down and ate some fruit to replenish his blood sugar. Oh my god, his only task was to pay attention to the monitor and drink water...
Hey, isn't it the nurse's duty to pay attention to how many bags of water are hung up, how many bags are left, and to change the water regularly?
After all the wounded who needed to be evacuated were evacuated, and those who didn't need to be evacuated were all lying there receiving infusions, the healers had time to gather around Grete.
Faced with the hard facts, more than one healer grabbed Gret curiously and asked questions. Gret also told everything he knew:
"With a large amount of blood loss, the key to first aid is to expand blood volume... 85% of blood is water, so replenishing a lot of fluids is more important than anything else..."
"How to judge the amount of blood loss? In addition to being at the scene and making visual estimates, you can also estimate based on the condition of the injured...
Generally speaking, after losing about 750ml of blood, the heartbeat will accelerate, but the blood pressure and breathing will not change much;
After losing about 1000-1250ml of blood, the patient will have tachycardia, systolic blood pressure may decrease, and the pulse pressure difference will decrease..."
He was surrounded by two circles of elves, each holding a notebook and remembering not to raise his head.
When Grete finished talking about level 3 and level 4 hemorrhagic shock and started talking about rehydration, someone immediately asked urgently:
"Then, wouldn't it be enough to replenish the fluids quickly? If all the fluids are infused at once, wouldn't they be able to recover quickly?"
He stretched out his hand and waved around, his fingers crossing a large semicircle, pointing to the soldiers lying under the shade of the trees and receiving infusions:
"Why do you have to do it so slowly?"
"That's it! That's it!" Under the shade of the tree, more than one head was raised. Soldiers with needles and liquid hanging on their elbows and collarbones shouted weakly with pale faces:
"Give us a magic spell! Shoot a rehydration magic, and then a blood replenishment magic, and then we can go to the battlefield again!"
"Shut up!"
Grete scolded them with a dark face, especially Bernard. Grete slapped him on the forehead several times, slapped him on the forehead, and forced him to lie down, and then turned to the healers:
"Don't replenish fluids too quickly! It's okay to do it a little faster - but if you inject so much in one minute, or one second, you'll get into trouble!"
"What?!"
"Don't believe it? When the rehydration magic is developed and tested, I'll ask you to come and see--"
This statement temporarily suppressed the healers' questions. Immediately, another elf raised his hand:
"How much can you lose?"
"For a single major bleeding of more than 1,500 ml, 2,000 ml of fluid should be infused in one hour. Generally speaking, there will be no problem."
Gretel was a senior emergency surgeon in his previous life. He handled this kind of problem very skillfully and without any hassle:
"Don't ask questions now, listen to me! The way to replenish fluids is to open a venous access. For rescue of major bleeding, it is best to open a central vein-"
"What?"
"What?!"
Poor elf healers, they have never heard of these professional medical terms. They know about veins, but what is a central vein?
While he was making random inquiries, a translucent light and shadow had already stood up in front of everyone.
Heart, lungs, and systemic vascular circulation. The red lines are arteries and the blue lines are veins. A circle of shadowy dotted lines in the middle cuts off these red and blue lines:
"Central vein refers to the large veins close to the heart, including the bilateral internal jugular veins, subclavian veins, bilateral innominate veins, superior and inferior vena cava..."
Following his instructions, those large veins became brighter one by one and beat vigorously. The healers looked at each other, and the quickest ones shouted:
"How do you get these veins in?"
"Yeah! So close to the artery next to it!"
"If you're not careful, you can poke the main artery in your neck!"
This is what Gretel expected. Central venous puncture is extremely difficult and cannot be performed by non-trained medical staff. Just these elves, don't they have enough training to let them get started?
Absolutely impossible!
Central venous infusion, and opening the bone marrow cavity just in case, just to show them and let them know that there is this method. As for the specific operations that these elves can use——
"If it is not possible to open a central vein, you can open a few more peripheral large veins. For example, the axillary vein, basilic vein, popliteal vein, great saphenous vein..."
The blood vessels on the limbs lit up one by one. Only then did the healer sigh with relief:
It's okay, okay. Let him find these blood vessels and let him poke them in with a needle. It doesn't seem difficult.
Looking around, the soldiers who were still receiving infusions saw that most of the vines were connected to the blood vessels of their limbs. If they followed the example, they should be able to do it...
However, there are still only a few healers who are so relieved. Most of the healers still look embarrassed, and a few of them whisper:
"Can't you use magic... You have to stick a needle in... What if it's poked crookedly, what if it's penetrated, what if the needle is crooked..."
Gretel took a deep breath.
Yes, this is also a problem of the lack of skilled operators. I remember when he was in Nevis, training a group of apprentices to inject penicillin, and they had to press the gourd to float the gourd to the point of death;
Intravenous injection is much more difficult than intramuscular injection. How can it be so easy to train a batch of masters in a short time?
"Forget it... I'll go back and think about it and try to make a rehydration spell..."
