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

Chapter 435 CT ah CT, how to do magic CT

"Stuck in the esophagus...?"

Elder Gu Shan touched his neck hesitantly.When he tried to touch the old hunchback's neck again, he was stopped by Gretel:
"Don't touch it. It's stuck here in the chest. It's about the same level as the second rib. It's very deep and you can't touch it. You can use [Detect Magic] to see—"

He knelt down on one knee and pointed out the location for Elder Gu Shan.At the same time, he frowned and thought hard:

How to check it?

How to ensure the safety of surgery?
It is not difficult to remove esophageal foreign bodies, especially those stuck in the chest.Even if Grete is not an ENT doctor, he has a good idea of ​​the general operation idea:

If there is no perforation, it can be properly removed with an esophagoscope-the natural deism alien vine version:
Even if a foreign body in the esophagus pokes a hole in the esophagus, a hole can be opened in the chest cavity for thoracoscopic surgery, and with a gastroscope, the thing can be squeezed out;
What?A foreign object poked a hole in the aorta? ——Aortic stent graft, oh, alien vine version, aortic therapy!Or let the thoracoscope wait by the side, and once the foreign body in the esophagus is taken out, the treatment will be thrown here?
It is not impossible to have.However, all of this has a premise:
diagnosis.

Esophageal foreign bodies, if they are simple in shape and regular in appearance, such as coins, can be diagnosed with plain X-ray films.However, for esophageal foreign bodies with complex, irregular and sharp shapes, especially those with possible perforation, as we all know, the most reliable diagnostic methods are:

CT.

Only CT can clearly show the size, shape, and location of foreign bodies in the esophagus, and whether they have penetrated into surrounding tissues, such as the trachea, aorta, etc.And, are there any complications, where is the perforation, where is the inflammation, where is the suppuration.

In this regard, X-rays can only look at the plane, and the barium cotton is easy to hang on foreign objects to aggravate the damage (by the way, there is no barium cotton in Gretel), and the B-ultrasound is not symptomatic at all.Other inspection methods are not as good as it when bundled together.

But where did he go to find a CT machine? !

Gretel thought hard.Looking sideways, Elder Gu Shan had already stood up, his face pale:

"How did it get stuck here? Can you take it out? Or... let him swallow it?"

"You can't swallow it!" Gretel was startled.Don't give a rice ball, or anything else, let the patient chew it, try to swallow the foreign body together!
"His position is extremely dangerous! Next to it is the largest blood vessel in the human body, which leads directly to the heart! If you move a little, the handle of the spoon will pierce the esophagus and penetrate the blood vessel, and the whole person will be finished!"

"Then what should we do?" Cold sweat dripped from Elder Gu Shan's forehead.In this situation, if he encounters it alone, he can only resign himself to fate.Luckily Gretel is here now—

"Your Excellency, you must save him! Hongshi Village only has one healer, the old hunchback. If he dies, the apprentice is still young, and the village will be in trouble! We live in the wasteland, without a healer, there will be a sick casualty How are you doing?"

"Okay, okay, don't worry, I will do my best." Gretel supported him and comforted him repeatedly.Then turn around:

"Cerilla!"

"Hey! What?"

"Help me look after the patient. If the condition suddenly deteriorates, throw healing." He pointed to the center of the old hunchback's sternum, which was at the same height as the second rib:
"Don't be stingy and lose the big one. I want to think about something."

"Okay!" The silver dragon girl responded, and wanted to squat down, then raised her head and glared at the white wolf opposite:
Don't come here!
[White Wolf] Wulfgen snorted coldly.He wanted to raise his fist to demonstrate, but he hesitated again with a movement of his arm:
The opposite is also an elf girl.Even with strange strength, she could throw him away easily, but she was still a petite and slender elf girl.Show off your force directly, it seems like you are bullying...

Just after hesitating, a person came running over with a thump, thump, and a shake of the ground.Bernard set up the carriage, ran over to stop next to Gretel, and took the place of the silver dragon girl.Look at the opposite side and puff up your chest:

The boss said to clear the field, so no one can disturb his treatment!
In the tense silence, Gretel thought quickly.He can't do CT of the whole chest, the amount of calculation is too large, beyond his ability; but, how about only one layer?

The principle of CT is nothing more than dividing a flat layer into 64 grids or more grids.Then, according to the ability of different parts of the body to absorb X-rays, they are marked as high absorption areas, medium absorption areas and low absorption areas.

Then, the radiation source is passed around the patient in a circle.Combine the received information and superimpose all the points into a plan...

I don't need many, I just need two, three, up to four images no bigger than 10x10cm.So, for the sake of the patient's life, can we manually record, manually calculate, and try our best?
Walk the path that the predecessors walked... After all, the earliest CT images are nothing more than this...

He gritted his teeth and made up his mind.This situation is not serious, so take this opportunity and try it out.Even if the diagnosis is wrong, I am confident that I can save it. Even if I miss, there will be Cerilla by my side, and someone will output powerful healing skills...

"Cerilla, take good care of him." Gretel said in a low voice, rustling, and began to take out a pen and notebook:

"I'm going to try a new way of diagnosis. If successful, it should save a lot of people."

Is there a new way to diagnose?
The silver dragon girl's eyes brightened.She nodded vigorously, squatted on the spot, and stared at the hunched barbarian without blinking.Not long after, [hunchback] Whitefern moved and groaned in pain:

"Well……"

"Don't move! Don't move!" Gretel immediately jumped down nervously.The foreign body in the esophagus is close to the aortic arch. Clinically, this situation requires an absolute supine position, so as not to use a little force and the foreign body directly penetrates into the aorta.But now, I have to work around it:
"Bernard! Bring me a chair! One with a back!"

"Come here!" Before Bernard searched all over the place, Elder Gushan gave an order, and a young man had already brought a wooden stool over, and tied the wooden boards against the legs of the stool.According to Gretel's request, carefully adjust the height of the planks so that the old man does not hinder the swollen bag on his back:
"Help him up! Be as gentle as possible, don't force him, don't force him at all! Put him on the chair and let him sit upright! Sit still, keep your back straight, good! Cerilla, imprisonment !"

Although the spiral CT is performed lying down, Gretel thought to himself that the [Endless Ink Pen] can circle the old man, but he can't lie flat and turn against the old man.As for lying under the old man, using magic to control the patient to lie down and turn...

Make up your mind, it's really beautiful.Forget it, let the patient sit directly in accordance with the practice of the first generation of CT experiments!
