Chapter 595: Want to see the blood flow in your heart? Develop new magic, you pay
The patient's family asked for more proof methods, but Grete was not angry.
The patient or the patient's family's right to know is their right. Otherwise, if you say my child has a ventricular septal defect, does he have a ventricular septal defect?
You say he has cervical erosion, but he still has cervical erosion! How many hospitals and unscrupulous doctors deceive patients like this!
Moreover, ensuring the patient's right to know can also improve compliance, thereby improving the effectiveness of treatment. Let alone major surgery, when a nurse gives an injection, she must first explain clearly to the patient what is being done.
In his previous life, unless he was extremely busy, he would still hold the film and test sheet, draw a schematic diagram of the operation, and explain it carefully to the patient...
If you can't explain it, if it's unclear, that's the doctor's problem, not the patient's.
However, cardiovascular angiography...how to do this thing?
The principle of cardiovascular angiography is actually very simple. It is nothing more than injecting contrast agent into the blood vessels, letting it flow with the blood, and then turning on X-rays.
The contrast agent is developed under X-rays, and at the same time, the process of developing the heart and blood vessel cavities is photographed using rapid photography, television photography, or tape recording.
However, for Gretel in this world, the difficulty is extremely high. Without him, there is no developer.
The developers used for cardiovascular imaging in previous lives, such as diatrizoate meglumine, such as Euvitex, iohexol, Onapex...
Once the doctor writes a prescription, it can be picked up from the pharmacy, so there is no need to worry. But now, where can I find it?
Rub by hand?
Just kidding!
For example, non-ionic contrast agents for children, such as iohexol.
Its chemical name is 5-[acetyl(2,3-dihydroxypropyl)amino]-N,N'-bis(2,3-dihydroxypropyl)-2,4,6-triiodo
-1,3-Phenyldicarbonamide……
If it was silver nitrate, silver ammonia solution, or iodine, Grete would just rub it together and have a look. For such a complex compound, he had only one idea:
Probably after becoming a legend and living another three to five hundred years, the technology in this world will be able to produce this thing, right?
So Grete had no choice but to find another way. Since he couldn't open the chest, let the patient's family see the heart defect under direct vision;
You cannot terminate the contract with the snake and let the patient's family see the heart condition with the snake's eyes;
Explain to them electrocardiograms, X-rays and echocardiograms, but they don’t understand...
Then, use vines or other methods to send a secret eye into the heart so that people can see what is going on in the heart?
Or, is there any other way?
Gretel thought hard for a long time, and finally raised his brows and looked at Viscount Aylwin sitting opposite. With this change of expression, he clearly heard Viscount Aylwin let out a long sigh of relief...
Oh, how pitiful the hearts of parents in the world are. Even though they are really afraid of him and afraid that he will fall out and not treat him, they still have to bite the bullet and ask...
Grete tried his best to smile and make his face friendly. He slowed down his speech and said softly:
"We don't have magic that shows the direction of blood flow in the heart yet. In this way, I think Mr. Ling's condition is okay. If you are willing to wait, I can try my best to study it, but"
"Any conditions are acceptable! If you want money or people, just ask!"
Viscount Alwin nodded repeatedly. He patted his chest hard with his big and generous hand, making a dull sound.
This 30-year-old man has a straight waist and a military bearing. He looks like a knight. However, he has strands of gray hair on his temples.
...It's not easy to ask for people, and no one here can help you. You really need money. After all, a new research needs research funds anyway...
Gretel smiled slightly and spoke softly. Of course, the purpose was to prevent the other party from jumping up and running away:
"However, since this magic was developed solely for your needs, I'm afraid you will have to bear the research funding."
"this……"
Viscount Alwin's expression froze. Master Nordmark's request was absolutely reasonable in terms of logic:
After all, it is his own request to show the direction of blood flow in the heart. The magician is willing to research spells for him, which has given him a lot of face. Which magician doesn't have more than ten or twenty projects in his hand, and you say he wants to study it?
Are they going to jump in line for you?
But, paying for research? Are you kidding me? That’s the magician’s research! If it goes well, burning ten or twenty thousand gold coins is not a problem at all. If it doesn’t go well?
If it doesn't go well, it will be a bottomless pit. If he fills the entire viscounty, he doesn't know whether it will be filled completely.
Grete also saw his hesitation. He coughed lightly:
"Don't worry, I will try to reduce the research costs as much as possible. In this way, I will not charge the casting fees, and you only need to bear the cost of high-value consumables, okay? If you are worried, you can also send personnel to supervise the use of consumables..."
At this point, Viscount Aylwin could no longer shirk it. He laughed and stood up:
"What are you talking about, Mr. Master? You specialize in researching spells for us. If I don't trust you anymore, what will happen to me? There is no need for supervision. I will pay 1,000, no, 2,000 gold coins for the first research fund?"
It's great to deal with rich people. Two thousand gold coins, I wonder how much money can be saved to cover the treatment expenses of the poor.
Grete smiled brightly.
He retreated to the back building, rolled up his sleeves, and began to try angiography. Well, the first option is to use the secret eye to try to enter the heart...
Take out the magic equipment, summon the secret eye, and adjust the size. The diameter is reduced from 1 inch to 1 centimeter, to 5 millimeters, to 3 millimeters...
He can't shrink anymore. He has reached the limit. If he wants to shrink again, he has to wait until he reaches level 7, learns the magic of the Mystical Eye, and successfully dismantles it.
And the diameter of 3 mm... Gretel came out and walked around, looked at the rabbit in the cage, and shook his head:
It definitely can't pass through the rabbit's radial vein, which will burst in an instant. There seems to be no way through the child's radial vein or radial artery.
The first plan failed. Gretel continued his efforts and tried the second plan:
Inject magical energy into the rabbit's body to allow it to manifest.
Medical common sense: You can use non-invasive examination methods, but do not use invasive examination methods. You can take medicine without injections, you can have intramuscular injections, but not intravenous injections...
Every time a barrier is jumped, the risk increases exponentially.
He immobilized the rabbit with the magic of anesthesia, and then condensed a ball of healing energy and sent it into the rabbit's radial vein. In the meditation field of [Detection Magic], the ball of energy entered the rabbit's body and immediately dispersed on the spot, along the
Muscles and bones spread outward...
In the meditation field of vision, a small firework seemed to light up. As for running along the blood vessels and illuminating the image of the blood vessels, I'm sorry, they don't exist.
Well……
It seems, it seems, that the only way to inject magic potions is...
Okay, here comes the third plan. Gretel took a deep breath and solemnly wrote down in the experiment record:
"Inject magic potion into the blood vessels of experimental animals, and then use [Detection Magic] to observe its flow route. The selection of magic potion must be reliable and cheap while ensuring safety."
There are many types of potions in the magic world. Taking standard potions as an example, the cheapest first-level potions, such as jumping potion and spider walking potion, are available in the trading hall of the White Tower all year round, and the price is stable at 50 gold coins;
Slightly more advanced potions, such as insight potions, swimming potions, and stealth potions, as long as they are not suddenly needed in large quantities, the price is stable at 150 gold coins. Adventurers buy them all year round, and there is an endless stream of them.
But Gretel didn't consider this at all. Most of the above potions were for drinking, and a few of them had problems with applying them. The gastrointestinal barrier was blocked. If they really had to be injected into the muscle blood vessels, the safety would be very worrying.
so
"Bring a bottle of [Cure Minor Injuries] potion over here!"
A bottle of [Cure Minor Injuries] potion is also 50 gold coins, the average price. What? Treat minor injuries?
What kind of medicine should be used for minor injuries? I can lick a three- to four-centimeter wound by myself without resorting to healing techniques. Adventurers who work hard outside in wind and rain are really not that valuable.
Gretel took matters into his own hands, lined up a row of syringes, and sucked the potion into the syringes. [Treatment of minor injuries] potions are sold in standard bottles, one and a half inches high, about the thickness of a thumb. The potion content...
10ml.
Absorb 1 ml and inject it into the leg muscle of a rabbit. [Detect Magic] The magic image can be seen, but it is very blurry.
Draw another 1 ml and inject it into another rabbit. After five groups, if there is no abnormality, draw another 2.5 ml and inject it into the leg muscle of the sixth rabbit...
Okay, the 1ml version makes 5 pieces, and the 2.5ml version makes 6 pieces.
After finishing the procedure and observing for 1 hour, 11 rabbits found no abnormalities, and the increase in invasive blood pressure was within the normal range. The safety test passed the first level, and the effectiveness test is temporarily doubtful.
100 gold coins, wings and soaring.
Grete compared the weights of the rabbit and the little boy, and felt that 2.5 ml should be about the same. The contrast agent used in pediatric cardiovascular angiography is only a few dozen ml. He was gearing up and started to do the next step:
Take 1 ml of [Treat Minor Injuries] potion and inject it into the lower end of the rabbit's femoral artery...
[Detect Magic] fell, and the image of the magic energy lit up slightly along the blood vessels. Before it had flowed halfway through the anterior tibial artery, it was already so faint that it was invisible.
It's okay, as long as you can see it. Grete kept up his efforts and did 5 consecutive groups of the 1 ml version, and then 6 consecutive groups of the 2.5 ml version. The conclusion is that the safety is acceptable, but the contrast effect is not good.
The magic energy content is too small. 2.5 ml of healing potion cannot flow through the anterior tibial artery and cannot be seen.
For the second 100 gold coins, fly with wings.
So should we increase the pushing pressure, or use a better healing potion? [Treat moderate injuries] potion, 300 gold coins per bottle...
For the sake of money, Grete decided to check the safety of cardiovascular angiography first. He took the fifth bottle of [Treatment of Minor Injuries] potion and directly used vines to go up the blood vessels and lead to the rabbit's heart.
One, two, three, potion injection, start!
The experiment has just begun, and the 250 gold coins have been burned away.
Magic research is so expensive. Fortunately, there is a sponsor to pay the bill, otherwise...
