Chapter 600 Want to See the Heart’s Blood Flow? Develop New Magic, You Pay
The patient's family members asked for more proof methods, but Grete was not angry.
The patient's or 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 said he had cervical erosion, but he still had cervical erosion! How many hospitals and unscrupulous doctors deceive patients like this!
Moreover, ensuring patients' informed rights can also improve compliance and thus treatment effectiveness. Not to mention major surgery, even if a nurse gives an injection, she must first explain to the patient what she is doing.
In his previous life, whenever he wasn't extremely busy, he would still hold films and test sheets, draw schematic diagrams of surgeries, and explain them carefully to patients...
If you can't explain it, if you can't explain it clearly, 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. Nothing else, no developer.
Developers used for cardiovascular imaging in previous lives, such as diatrizoate meglumine, such as Euvitex, iohexol, Onipex...
Once the doctor writes a prescription, you can pick it up from the pharmacy, so you don’t have to worry at all. But now, where can I find it?
Hand rub?
Just kidding!
For example, consider non-ionic contrast agents used in 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-phthalamide……
If it was silver nitrate, silver ammonia solution, or iodine, Grete would just rub it with his hands and take a look. For such a complex compound, he only had 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 Gretel had no choice but to find another way. Since he cannot 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, are there any other ways?
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 Alwin let out a long breath of relief...
Alas, how pitiful the hearts of parents in the world are. Although I was really afraid of him, afraid that he would fall out and not treat me, I still had to ask...
Grete tried his best to smile and make his face more 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 Aylwin nodded repeatedly. The big and generous hand patted the chest hard, making a dull sound.
This 30-year-old man has a straight back and a military bearing. He looks like a knight. However, there are strands of gray hair on the temples.
...It’s not easy to ask for help, and no one here can help you. Money is really needed. After all, a new research needs research funds no matter what...
Gretel smiled slightly and spoke softly. Of course, the purpose is to try not to make the opponent jump up and run away:
"However, since this magic was developed solely for your needs, I'm afraid you will have to bear the research funding."
"this……"
Viscount Aylwin's expression froze. Master Nordmark's request is absolutely reasonable in terms of reason:
After all, it was his own request to show the direction of blood flow in the heart. The magician was willing to research the spell for him, which was a huge favor. What magician doesn't have dozens or twenty projects in hand? If you say you want to research, they will jump in the queue for you?
But paying for research? Just kidding, that’s the magician’s research! If it goes well, burning ten or twenty thousand gold coins is nothing at all. But if it doesn't go well?
If it doesn't go well, it will be a bottomless pit. If he fills his entire viscounty, he doesn't know if it can be filled completely.
Grete also noticed 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 cost of casting spells, 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. He laughed and stood up:
"What are you saying, Mr. Master? You specialize in researching spells for us. If I don't trust you anymore, what will happen to me? No need for supervision. I will pay 1,000, no, 2,000 gold coins for the first research fund?"
It's nice to hang out with rich people. Two thousand gold coins, I wonder how much cost can be saved to cover the treatment expenses of the poor.
Grete smiled brightly.
He retreated to the backstairs, rolled up his sleeves, and began trying an angiogram. Well, the first option is to use the secret eye to try to enter the heart...
Take out the magic equipment, summon the arcane eye, and adjust the size. The diameter shrinks from 1 inch, to 1 cm, to 5 mm, to 3 mm...
Can't shrink anymore. He has reached the limit, and 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:
This will definitely not 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. Grete kept up his efforts and tried the second option:
Infuse the rabbit with magical energy to manifest.
Medical common sense: If you can use non-invasive examination methods, do not use invasive examination methods. You can take medicine without injections, you can give intramuscular injections without intravenous injections...
Every time a barrier is jumped, the risk increases exponentially.
He immobilized the rabbit with the magic of anesthesia, then condensed a ball of healing energy and sent it into the rabbit's radial vein. In the meditation vision of [Detect Magic], the energy entered the rabbit's body and immediately spread out, spreading outward along the muscles and bones...
In the meditation field of vision, a small firework seemed to light up. As for running along the blood vessels and taking out images of the blood vessels, sorry, that doesn't exist.
Well……
It seems, it seems, that the only way to inject magic potions is...
Okay, here comes the third option. Grete 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 wizarding world. Take 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 needed suddenly or in large quantities, the price is stable at 150 gold coins. Adventurers buy them all year round, and the flow never stops.
But Gretel didn't think about this at all. Most of the above potions are drank, and a small part are applied - if there is any problem, the gastrointestinal barrier is blocked. If it is really injected into the muscle blood vessels, the safety is very worrying.
so--
"Bring me a bottle of [Cure Minor Injuries] potion!"
A bottle of [Cure Minor Injuries] potion is also 50 gold coins, which is an average price. What? Treat minor injuries?
What kind of medicine is needed 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 or 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. [Treat minor injuries] Potions are sold in standard bottles, one and a half inches high and about the thickness of a thumb. Potion content...
10ml.
Take 1 ml and inject it into a rabbit leg muscle. [Detect Magic] Magic images can be seen, but they are very blurry.
Pipette another 1 ml and inject 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 first pass of the safety test was passed, but the validity test is temporarily doubtful.
100 gold coins, wings and soaring.
Grete compared the weight of the rabbit and the little boy, and felt that 2.5 ml should be about the same - anyway, the contrast agent used in pediatric cardiovascular angiography is only a few dozen ml. He geared up and started to take 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 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 could no longer be seen.
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 imaging effect is not very 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, you can soar 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 imaging first. He took the fifth bottle of [Cure Minor Injuries] potion and used the vines to go up the blood vessels and reach 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...
