The patientâs family members demanded more concrete proof, but Garrett wasnât 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 itâs cervical erosion, and it turns out to be cervical erosion! How many hospitals and unscrupulous doctors deceive patients just like this!
Moreover, ensuring the patientâs 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 patientsâŠ
If explanations were insufficient or unclear, that was a problem on the doctorâs part, not the patientâs.
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 worldâs 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 enopaqâŠ
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,Nâ-bis(2,3-dihydroxypropyl)-2,4,6-triiodo-1,3-benzenedicarboxamideâŠ
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 couldnât open the chest to let the patientâs family see the heart defect directly;
Couldnât release the little snake from its contract to let the family see the heart condition through the snakeâs eyes;
And since they wouldnât understand explanations through electrocardiograms, X-rays, and echocardiogramsâŠ
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 reliefâŠ
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 askâŠ
Garrett tried to smile more warmly, making his facial expression more amiable. He slowed his speech and said softly:
âThe magic to display the direction of blood flow in the heart, we donât have it here just yet. Thus, seeing the condition of your son isnât too severe, if youâre willing to wait, I can try to research it, butââ
âAny condition is fine! Money, manpower, just name it!â
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.
âŠManpower isnât really necessary here, thereâs no one available for that. Money is genuinely needed, after all, every new research requires fundingâŠ
Garrett smiled slightly, speaking in a low and gentle voice. Of course, his aim was to prevent the other party from abruptly leaving:
âHowever, considering that this magic is being developed specifically for your needs, the research expenses will unfortunately have to be borne by you.â
âThisâŠâ
Viscount Erwinâs face stiffened. Mage Nordmarkâs 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 doesnât 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, thatâs the realm of a magicianâs 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:
âRest assured, I will try to reduce the research expenses. Thus, I wonât charge for casting the spell, you just need to bear the cost of high-value consumables, is that acceptable?âIf youâre not confident, you can also send someone to monitor the consumption of materialsâŠâ
At this point, Viscount Erwin really couldnât decline further. He laughed heartily, standing up:
âWhat are you saying, Mage? You are specifically researching a spell for us, if I still donât trust you, what would I be? No need for supervision, shall I pay the first research installment of 1000, no, 2000 gold coins?â
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 EyeâŠ
Taking out magical equipment, summoning an Arcane Eye, adjusting its size. From 1 inch, reducing to 1 centimeter, to 5 millimeters, to 3 millimetersâŠ
It couldnât shrink further. It had reached its limit; to shrink further, heâd 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 couldnât pass through the rabbitâs radial vein; it would burst instantly. Passing through a childâs radial vein or artery seemed unlikely too.
The first plan failed. Garrett persisted and tried a second plan:
Injecting magical energy into the rabbitâs body to facilitate imaging.
Medical knowledge: If a non-invasive inspection method is available, donât use an invasive one. If medication can be taken orally, donât inject; if it can be done through intramuscular injection, donât use intravenousâŠ
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 rabbitâs radial vein. In the meditative vision of [Detect Magic], that bundle of energy entered the rabbitâs body and immediately dispersed on the spot, spreading outward along the muscles and bonesâŠ
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, thatâs not happening.
UhâŠ
It seems, really, that injecting magical potions is the only optionâŠ
Alright, the third plan takes the stage. Garrett took a deep breath, solemnly recording in the experiment log:
âInjecting a magical potion into the experimental animalâs 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 varietyââ
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 Towerâs trading hall, with a stable price of 50 gold coins;
Slightly more advanced potions, like Insight, Swimming, or Stealth potions, as long as thereâs no sudden, large demand, stabilize at 150 gold coins. Adventurers purchase them year-round, in constant flow.
But Garrett didnât consider these at all. Most of the above potions are to be drunk, a few applied topicallyâany issues, and the gastrointestinal barrier has it covered. Really injecting into muscle vessels, that safety is very questionable.
Soâ
âBring a bottle of [Cure Light Wounds] potion here!â
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, itâs not worth using a healing spell. In wind and rain, adventurers out battling donât 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 contentâŠ
10 milliliters.
Drawing 1 milliliter, he injected it into a
rabbitâs 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 rabbitâs leg muscleâŠ
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 rightâafter 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 rabbitâs femoral arteryâŠ
[Detect Magic] activated, the magic energy image along the blood vessel, lighting up just a little bit. It hadnât 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 couldnât 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 bottleâŠ
Considering the money, Garrett decided, letâs 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 rabbitâs heart.
One, two, three, potion injected, start!
The experiment had just begun, and 250 gold coins were already burned away.
Magical research, itâs just that expensive. Good thing thereâs a sponsor to foot the bill, otherwiseâŠ
