A Hospital in Another World?-Chapter 595: Want to See Blood Flow in the Heart? Develop New Magic

The patient’s family members demanded more concrete proof, but Garrett wasn’t angry.

The right to know for the patient or their family is indeed their rightful entitlement. Otherwise, if you say my child has a ventricular septal defect, is it truly so just because you say it?

You claim it’s cervical erosion, and it turns out to be cervical erosion! How many hospitals and unscrupulous doctors deceive patients just like this!

Moreover, ensuring the patient’s right to know also improves compliance, thereby enhancing treatment outcomes. Not just for major surgeries, even when a nurse administers an injection, they must first explain clearly what is being done.

In his past life, unless utterly swamped, he would hold the films, the test results, sketch a simple diagram of the surgery, and explain everything meticulously to the patients…

If explanations were insufficient or unclear, that was a problem on the doctor’s part, not the patient’s.

But cardiovascular angiography... how exactly does one perform that?

The principle of cardiovascular angiography is actually quite simple. It simply involves injecting a contrast agent into the blood vessels, allowing it to flow with the blood, and then turning on the X-ray.

The contrast agent becomes visible under X-ray, and the process of the heart and blood vessels becoming visible is captured using rapid filming, television photography, or magnetic tape recording.

However, for this world’s Garrett, the difficulty was exceptionally high. Why? Because there were no contrast agents.

Contrast agents used in past life cardiovascular angiography, like iohexol, omnipaque, iodixanol, or enopaq…

A doctor would just write a prescription, and it could be picked up from the pharmacy, no worries at all. But now, where would he find such a thing?

Hand-making it?

You must be joking!

For instance, the non-ionic contrast agents used for children, like iodixanol.

Its chemical name is 5-[acetyl(2,3-dihydroxypropyl)amino]-N,N’-bis(2,3-dihydroxypropyl)-2,4,6-triiodo-1,3-benzenedicarboxamide…

If it were something like silver nitrate, silver ammonia solution, or tincture of iodine, Garrett might just try to make it himself. But for such a complex compound, he only had one thought:

Maybe after becoming a legend and living another three to five hundred years, the technology of this world might be able to produce this stuff.

So, Garrett had to find another way. Since he couldn’t open the chest to let the patient’s family see the heart defect directly;

Couldn’t release the little snake from its contract to let the family see the heart condition through the snake’s eyes;

And since they wouldn’t understand explanations through electrocardiograms, X-rays, and echocardiograms…

Then, would sending an Arcane Eye into the heart with vines or some other method, to let them see the condition inside the heart, work?

Or, perhaps, there was some other method?

Garrett pondered deeply for a long time, finally smiling as he looked at Viscount Erwin sitting opposite him. As his expression changed, he clearly heard Viscount Erwin breathe a long sigh of relief…

Ah, the heart of a parent worldwide is indeed pitiable. They are truly scared of him, afraid that he might refuse to treat them if angered, yet they still had to muster the courage to ask…

Garrett tried to smile more warmly, making his facial expression more amiable. He slowed his speech and said softly:

“The magic to display the direction of blood flow in the heart, we don’t have it here just yet. Thus, seeing the condition of your son isn’t too severe, if you’re willing to wait, I can try to research it, but—”

“Any condition is fine! Money, manpower, just name it!”

Viscount Erwin nodded repeatedly. His broad hands thumped his chest, producing a dull thumping sound.

This man in his early thirties stood straight, every movement exuding a military demeanor, appearing every bit a knight. Yet, his temples were prematurely streaked with white.

…Manpower isn’t really necessary here, there’s no one available for that. Money is genuinely needed, after all, every new research requires funding…

Garrett smiled slightly, speaking in a low and gentle voice. Of course, his aim was to prevent the other party from abruptly leaving:

“However, considering that this magic is being developed specifically for your needs, the research expenses will unfortunately have to be borne by you.”

“This…”

Viscount Erwin’s face stiffened. Mage Nordmark’s request was absolutely reasonable:

After all, displaying the direction of blood flow in the heart was his own request, and for a magician to conduct targeted research on a spell just for him

was already a huge honor. Which magician doesn’t have a dozen or twenty projects at hand, and you expect to jump the queue just by asking?

But, to bear the research expenses? You must be joking, that’s the realm of a magician’s research! If it goes well, burning through ten or twenty thousand gold coins is nothing, but if not?

If not, it becomes a bottomless pit, and even filling it with his entire viscountcy might not be enough.

Garrett saw his hesitation and cleared his throat slightly:

“Rest assured, I will try to reduce the research expenses. Thus, I won’t charge for casting the spell, you just need to bear the cost of high-value consumables, is that acceptable?—If you’re not confident, you can also send someone to monitor the consumption of materials…”

At this point, Viscount Erwin really couldn’t decline further. He laughed heartily, standing up:

“What are you saying, Mage? You are specifically researching a spell for us, if I still don’t trust you, what would I be? No need for supervision, shall I pay the first research installment of 1000, no, 2000 gold coins?”

Dealing with wealthy people is indeed pleasant. Two thousand gold coins, who knows how much cost it could save to fund treatment for the poor.

Garrett beamed a bright smile.

He returned to the back building, rolled up his sleeves, and began to attempt vascular imaging. Hmm, the first plan, trying to enter the heart with an Arcane Eye…

Taking out magical equipment, summoning an Arcane Eye, adjusting its size. From 1 inch, reducing to 1 centimeter, to 5 millimeters, to 3 millimeters…

It couldn’t shrink further. It had reached its limit; to shrink further, he’d have to reach Level 7, learn the Arcane Eye spell, and successfully dissect it.

And a 3-millimeter diameter… Garrett walked around, looked at the cage with rabbits, and shook his head:

It definitely couldn’t pass through the rabbit’s radial vein; it would burst instantly. Passing through a child’s radial vein or artery seemed unlikely too.

The first plan failed. Garrett persisted and tried a second plan:

Injecting magical energy into the rabbit’s body to facilitate imaging.

Medical knowledge: If a non-invasive inspection method is available, don’t use an invasive one. If medication can be taken orally, don’t inject; if it can be done through intramuscular injection, don’t use intravenous…

Skipping any barrier brings exponentially increasing risks.

He held the rabbit with anesthetic magic, then gathered a bundle of healing energy and sent it into the rabbit’s radial vein. In the meditative vision of [Detect Magic], that bundle of energy entered the rabbit’s body and immediately dispersed on the spot, spreading outward along the muscles and bones…

In the meditative vision, it was like a tiny burst of fireworks. As for flowing along the blood vessels to produce a vascular image, sorry, that’s not happening.

Uh…

It seems, really, that injecting magical potions is the only option…

Alright, the third plan takes the stage. Garrett took a deep breath, solemnly recording in the experiment log:

“Injecting a magical potion into the experimental animal’s blood vessels and using [Detect Magic] to observe its flow path. The selection of the magic potion must ensure safety first and foremost, choosing a reliable and cost-effective variety—”

The magical world has a plethora of potions. Taking standard potions as an example, the cheapest tier-one potions, like Jumping or Spider Climb potions, are perennially on sale in the White Tower’s trading hall, with a stable price of 50 gold coins;

Slightly more advanced potions, like Insight, Swimming, or Stealth potions, as long as there’s no sudden, large demand, stabilize at 150 gold coins. Adventurers purchase them year-round, in constant flow.

But Garrett didn’t consider these at all. Most of the above potions are to be drunk, a few applied topically—any issues, and the gastrointestinal barrier has it covered. Really injecting into muscle vessels, that safety is very questionable.

So—

“Bring a bottle of [Cure Light Wounds] potion here!”

A bottle of [Cure Light Wounds] potion, also 50 gold coins, average price. What? Cure minor wounds?

Minor wounds need what kind of potion, a three or four-centimeter cut, just lick it yourself, it’s not worth using a healing spell. In wind and rain, adventurers out battling don’t have such luxuries.

Garrett personally took charge, lined up a row of syringes, and drew the potion into the syringes. [Cure Light Wounds] potion, sold for external use in standard bottles, an inch and a half tall, as thick as a thumb. The potion content…

10 milliliters.

Drawing 1 milliliter, he injected it into a

rabbit’s leg muscle. [Detect Magic] could see the magic image, but it was very blurry.

Then drew another 1 milliliter, injected it into another rabbit. After five groups, observing no abnormalities, then drew 2.5 milliliters, injected it into the sixth rabbit’s leg muscle…

Alright, 5 rabbits with the 1-milliliter version, 6 rabbits with the 2.5-milliliter version.

11 rabbits completed, observed for 1 hour, all without abnormalities, invasive blood pressure high within normal range. Safety check for the first stage passed, effectiveness, still in doubt.

100 gold coins, soaring to the sky.

Garrett compared the weights of the rabbits and the little boy, thinking 2.5 milliliters should also be about right—after all, pediatric cardiovascular imaging uses only a few dozen milliliters of contrast agent. He rubbed his hands together, ready for the next step:

Drawing 1 milliliter [Cure Light Wounds] potion, injecting it into the lower end of the rabbit’s femoral artery…

[Detect Magic] activated, the magic energy image along the blood vessel, lighting up just a little bit. It hadn’t even flowed past half of the anterior tibial artery before it was gone, too faint to see.

No matter, seeing it at all is good. Garrett persisted, doing 5 sets of the 1-milliliter version, then 6 sets of the 2.5-milliliter version. The conclusion was, the safety was passable, but the imaging effect was poor.

The magic energy content was too low; 2.5 milliliters of [Cure Light Wounds] potion couldn’t even flow through the anterior tibial artery before becoming invisible.

The second 100 gold coins, soaring to the sky.

So, should he increase the injection pressure, or switch to a better healing potion? [Cure Moderate Wounds] potion, 300 gold coins a bottle…

Considering the money, Garrett decided, let’s first check the safety of cardiovascular imaging. He took the fifth bottle of [Cure Light Wounds] potion, directly using vines along the blood vessels ascending to the rabbit’s heart.

One, two, three, potion injected, start!

The experiment had just begun, and 250 gold coins were already burned away.

Magical research, it’s just that expensive. Good thing there’s a sponsor to foot the bill, otherwise…
