Chapter 435 CT, CT, How to Do Magic CT

"Stuck in the esophagus...?"

Elder Gushan touched his neck hesitantly. When he tried to touch the old hunchback's neck again, Gretel stopped him:

"Stop touching it. It's stuck here on the chest, about level with the second rib. It's very deep and you can't touch it. Use [Detection Magic] to take a look -"

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

How to check?

How to ensure the safety of surgery?

Esophageal foreign bodies, especially those stuck in the chest, are not difficult to remove. Even if Grete is not an otolaryngology doctor, he knows the general idea of ​​​​operation:

If there is no perforation, just use an esophagoscope - the otherworldly vine version of the God of Nature - to properly remove it:

Even if a foreign body in the esophagus pokes a hole in the esophagus, a hole can be made in the chest for thoracoscopic surgery, and a gastroscope can be used to remove the thing;

What? A foreign object poked a hole in the aorta? ——Upper aortic stent graft, oh, alien vine version, aortic treatment! Or let the thoracoscope wait nearby, and once the esophageal foreign body is removed, the treatment will be done?

It’s not impossible to have it. 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-rays. However, for esophageal foreign bodies with complex, irregular and sharp shapes, especially those with the possibility of perforation, it is well known that the most reliable diagnostic method is:

CT.

Only CT can clearly show the size, shape, and location of foreign bodies in the esophagus, and whether they have penetrated 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 see flat surfaces, barium cotton can easily hang on foreign objects and aggravate damage (by the way, Grete does not have barium cotton yet), and B-ultrasound is not correct at all. Other inspection methods, bundled together, are not as effective as this one.

But where can he find a CT machine? !

Grete thought hard. Looking sideways, Elder Gushan had stood up, his face pale:

"Why is it stuck here? Can you take it out? Or...let him swallow it?"

"You can't swallow it!" Grete was startled. Don't give a rice ball or anything else. Let the patient chew it and try to swallow the foreign object together!

"He's stuck in a very dangerous position! Next to it is the largest blood vessel in the human body, which goes straight to the heart! If he moves even a little, the handle of the spoon pierces the esophagus and penetrates the blood vessel, and the whole person will be dead!"

"What should we do?" Elder Gushan's forehead was dripping with cold sweat. If he encountered this situation alone, he would have to leave it to fate. Fortunately, Grete is here now——

"Your Excellency, you must save him! There is only one healer in Hongshi Village, Old Hunchback. If he dies and his apprentice is still young, the village will be in trouble! We live in the wilderness. Without a healer, there will be no casualties. How else are you going to live?”

"Okay, okay, don't worry, I will do my best." Grete supported him and comforted him. Then he turned his head:

"Cerella!"

"Hey! What?"

"You can help me keep an eye on the patient. If the condition suddenly worsens, I'll throw out the treatment." 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, lose the big one. I have something to think about."

"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 over!

[White Wolf] Wolfgen snorted coldly. He wanted to raise his fist to demonstrate, but then he hesitated after moving his arm:

The opposite side is also an elf girl. Even though she had strange strength and could easily throw him away, she was still a petite and slender elf girl. Directly showing off force seems like bullying...

As soon as he hesitated, a person came running over from the opposite side, and the ground shook. Bernard arranged the carriage and ran over to stand next to Gretel, taking the place of the silver dragon girl. Look at the other side and puff out your chest:

The boss said to clear the place, then no one can disturb his treatment!

In the tense silence, Grete thought quickly. He couldn't do a CT scan of the entire chest. The amount of calculations was too large and beyond his capabilities; but what about doing only one layer?

The principle of CT is just to divide a flat floor into 64 grids or more. 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.

The radioactive source is then moved around the patient. Combine the received information and superimpose all points into a plane map...

I don't need many images, I only need two, three, or at most four images, no larger than 10×10cm. So, for the sake of the patient's life, can we manually record, manually calculate, and try it once?

Walking through the path of our predecessors... After all, the earliest CT images were nothing more than this...

He gritted his teeth and made up his mind. This situation is not serious, so take this opportunity to give it a try. Even if the diagnosis is wrong, he is confident that he can be saved. Even if he misses, there will be someone with Cerela beside him who will be able to deliver powerful healing...

"Cerilla, keep an eye on him." Grete whispered, rustling, and began to take out a pen and notebook:

"I want to try a new diagnostic method. If successful, it should be able to save many more people."

Is there a new diagnostic method?

The silver dragon girl's eyes were bright. She nodded vigorously, squatted on the spot, and stared at the hunchbacked barbarian without blinking. Not long after, [Hunchback] Whitefin moved and let out a painful groan:

"Well……"

"Don't move! Don't move!" Grete immediately jumped down nervously. The foreign body in the esophagus is close to the aortic arch. Clinically, this situation requires lying absolutely flat to prevent the foreign body from directly piercing the aorta with a little more force. But now, I have no choice but to make some changes:

"Bernard! Bring me a chair! One with a backrest!"

"It's coming, it's coming!" Before Bernard could search all over the place, Elder Gushan gave the order, and a young man had already carried a wooden stool over and tied the wooden boards to the legs of the stool. According to Gretel's request, the height of the board was carefully adjusted so as not to interfere with the swelling on the old man's back:

"Hel him up! Try to be as gentle as possible, don't let him exert any force, not even a little bit! Put him on the chair and let him sit up straight! Sit firmly, back straight, good! Cerela, confinement technique !”

Although spiral CT scans were done while lying down, Gretel thought to himself that since the [Endless Ink Pen] could rotate around the old man, he couldn't lie down and spin facing the old man. As for lying under the old man, using magic power to control the patient to lie down and turn...

Just think about it, I really don’t look at the beauty of the painting. Forget it, let’s just follow the approach of the first-generation CT experiments and just let the patient sit down!
