It's not that hard to open a hospital in another world, right?

Chapter 1342 Rescue by transfusion?We can't learn, Mr. Gretel!

Replenish with spells...

This idea is theoretically feasible.Before Gretel, he had used [Detoxification Technique] to instantly drain the potassium chloride in the target's heart, or instantly infuse a large amount of potassium chloride...

Spreading out from here, it is not impossible to use magic to drive Ringer's liquid into the blood vessels.However, what kind of magic to use specifically still needs to be studied carefully.

Gretel pressed his mind, kept his hands and feet, and paid attention to the wounded soldiers.

After Bernard, other fighters were sent down one after another. Gretel straightened the bones one by one, connected muscles and tendons, replenished fluids, and used blood-replenishing magic...

An ancient tree with the functions of attack, defense and concealment was regarded by him as an infusion stand.Countless branches stretched from above, like bearing fruit, and a row of infusion bottles were hung.

——If Gretel hadn’t developed the rapid oxygen supply function, I’m afraid we still need to train the ancient trees, and put two blades in each of these elves’ noses, so that the soldiers who need it can breathe oxygen for a while…

In short, while the healers in the front were galloping on the front line, fighting and healing the soldiers, Gretel was in the middle and rear, running around without touching the ground.

Emergency rescue!
Emergency rescue!
Hemorrhagic shock, pneumothorax, hemopneumothorax, craniocerebral injury, visceral injury, lung contusion, cardiac arrest, tracheal rupture...

He walked under the old tree like a butterfly wearing flowers.He alone has played the function of nearly ten healers...

"Lie down! Lie down! Don't move!"

"Don't move your hands! Watch out for the needle! ——Oh, the blood is coming back again! If you move around again, I will let the ancient tree tie you up!"

"CPR!"

"Electric defibrillation!"

"Ashu, don't stop the group healing technique! Hold the blood line! Hold it!"

"Cerilla, go and change the water bottle for No. [-]! Pay attention to how many bottles he hung up!"

He was busy until the battle was over, and the healers rushing to the front line returned to the ancient tree one after another, and only then did the wounded take over.

Gretel wiped off his sweat and sat on the side eating some fruit to supplement his blood sugar.Damn, his task finally only remains to pay attention to the monitor and hang the water...

Hey, by the way, pay attention to how many bags of water are hung, how many bags are left, and change the water regularly, isn't this the responsibility of a nurse?
When those wounded who should be evacuated were all evacuated, and those who did not need to be evacuated were lying there receiving infusions, the healers had time to gather around Gretel.

Facing the iron-clad facts, more than one healer grabbed Gretel curiously, asking questions.Gretel also knew everything and said everything:
"A lot of blood loss, the key to first aid is to expand the blood volume... 85% of the blood is water, and a large amount of fluid is more important than anything else..."

"The method of judging the amount of blood loss? In addition to being on the scene at the time and visually predicting, it can also be estimated based on the state of the injured...

Generally speaking, when the blood loss is about 750ml, the heartbeat will speed up, and the blood pressure and breathing will not change much;

About 1000-1250ml of blood loss, the patient will have tachycardia, the systolic blood pressure may decrease, and the pulse pressure difference will decrease..."

There were two circles of elves around him, each holding a notebook, remembering not to look up.

When Gretel finished talking about the third and fourth grades of hemorrhagic shock, and started talking about rehydration, someone immediately asked anxiously:
"Then just fill in the fluid quickly? Can't they get better faster if all the fluid is infused at once?"

He stretched out his hand and waved it in a circle, and his fingers crossed a large semicircle, pointing at the soldiers lying in the shade of the tree and receiving the infusion:
"Why do you have to drip it slowly?"

"That's it! That's it!" Under the shade of the tree, more than one head raised up.On the elbows and collarbones, the soldiers who were poked with needles and drenched in liquid were pale and yelled weakly:

"Shoot a spell for us! Shoot a fluid replenishment spell, and then a blood replenishment spell, and then we can go to the battlefield again!"

"To shut up!"

Gretel scolded them with a dark face.Especially Bernard, Gretel slapped, slapped, slapped him on the forehead several times, forced him to lie flat, and then turned to the healers:

"The rehydration can't be too fast! It's okay to be a little faster-but if you infuse so much in one minute or one second, you will cause trouble!"

"What?!"

"Don't believe it? When the rehydration magic is developed, and when the experiment is done, I'll ask you to come and see—"

This statement temporarily suppressed the doubts of the healers.Immediately another elf raised his hand:
"How much can you lose?"

"For a single hemorrhage of more than 1500 ml, it is generally no problem to infuse 2000 ml of fluid in an hour."

Gretel was a senior emergency surgeon in his previous life, so he handled this kind of problem very skillfully, without thinking too much:

"Don't ask questions now, listen to me! The way to replenish fluids is to open the venous access. For the rescue of massive bleeding, it is best to open the central vein—"

"What?"

"what?!"

Poor group of elf healers, I have never heard of these professional medical terms.I know about veins, but central veins, what the hell is that?

While asking in confusion, a translucent light and shadow has stood up in front of everyone.

Heart, lungs, systemic vascular circulation, the red line is the artery, the blue line is the vein, and a faint dotted line in the middle cuts off these red and blue lines:
"Central vein refers to the large veins close to the heart, including bilateral internal jugular veins, subclavian veins, bilateral innominate veins, superior and inferior vena cava..."

Following his guidance, those large veins brightened up one by one, throbbing vigorously.The healers looked at each other, and the fast-talking ones shouted:
"How are these veins going to be poked in?"

"Yeah! It's so close to the artery next to it!"

"If you're not careful, you can poke the aorta in your neck!"

This was also expected by Gretel.Central venous puncture is extremely difficult, and non-trained medical staff cannot operate it. Just these elves, without years of training, let them get started?
Impossible!
Central venous infusion, and opening of the 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 the central vein cannot be opened, several large peripheral veins can be opened. 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 in relief:

so far so good.It doesn't seem difficult for him to find these blood vessels and let him poke them in with a needle.

Looking left and right, most of the vines are connected to the blood vessels of the limbs of the soldiers who are still infusion.They should be able to do it according to the gourd painting...

However, there are still a small number of healers who are relieved like this.Most of the healers were still showing embarrassment, and a few whispered:

"Can't you use magic... You have to poke a needle in it... What to do if you poke it crookedly, what to do if it's pierced through, what to do if the needle is crooked..."

Gretel took a deep breath.

Yes, this is also a problem of lack of skilled operators.Remember when he was in Nevis, he trained a group of apprentices to inject penicillin, they were dying, pressing the gourd to float the scoop;
Intravenous injection is so much more difficult than intramuscular injection. How can it be so easy to practice a batch of hands in a short period of time?
"Forget it... I'll go back and think about it, try to make a rehydration spell..."
