Chapter 538: When people can’t be treated, let’s treat thrombosis in dogs instead.

"Good advice is hard to take for the damned ghosts..."

Garrett stood on the hospital steps, watching the patient leave in a cloud of dust and finally shrugged helplessly and returned inside. What could he do? The hospital didn’t have the authority to detain patients and force treatment!

In his previous life, doctors could still grab hold of patients and plead with them. But in this world, a new problem had arisen:

The patient was too strong to fight.

This patient, whether a level 3 or level 4 warrior, was not someone Garrett, a mere level 1 warrior, could defeat without using magic.

He had no choice but to return to the hospital and gather the idle healers on duty to start an educational session:

"The reason that patient had a toothache is not due to dental issues, but a problem with his heart. The arteries that supply blood to the heart are blocked, leading to myocardial necrosis, which can involve other areas, from the navel up, including the teeth, in a heart attack-related pain!"

"If multiple teeth hurt and it’s unclear which one; if treatment and pain relief don’t alleviate the toothache; if dental examinations show no abnormalities and electrocardiograms show ischemic changes, then be wary of a heart attack!"

"In short, memorize that electrocardiogram magic! Don’t just wait for automatic alerts; recognize abnormal waveforms and understand what they mean!"

The healers nodded grimly. They were overwhelmed by the plethora of complicated ECGs they had to memorize.

Since arriving at Oakwood Hospital, there had always been a mountain of things to memorize, and before they could finish the old material, new stuff came pouring in. Previously, it was all about casting healing spells, which was so simple, but now...

"So, how do we treat it?"

A young priest from the Church of Nature timidly raised his hand. Garrett sighed deeply.

In his previous life, there was a mature set of treatments for heart attacks: intravenous thrombolysis, catheter thrombolysis, thrombectomy, stenting, or even coronary artery bypass grafting...

Of course, this also included pain relief, antiplatelet therapy, anticoagulation, antiarrhythmics, shock management, and heart failure treatment. But the problem was, he couldn’t perform most of these.

Thrombolysis? He didn’t have streptokinase, urokinase, tenecteplase, alteplase, or reteplase.

Coronary artery bypass? As if the patient would let him open their chest;

Electrical cardioversion? Sorry, although he was a disciple of the Lord of Thunder, he couldn’t yet perform electrical cardioversion with his bare hands;

Thrombectomy... he could swirl up saline in the abdominal cavity with a whirlwind at the vine entrance, but extracting blood clots from blood vessels... he feared he might break the vessels along with it.

He longed for the negative pressure aspirators of his previous life...

His face grew increasingly somber, and the healers in front of him became increasingly uneasy. The first to speak, the priest of the God of Nature, shrank back, leading the chorus:

"I’ll go memorize it!"

"Yes, I’ll go memorize it!"

"I’ll go memorize it!"

The healers scattered like birds and beasts. Garrett stood dumbfounded as he watched a group of students flee in panic:

"..."

Actually, I wanted to say that I have some ideas, but I need to try them out...

He silently turned around and went back to the research building deep inside the hospital. Necromancers and their apprentices were busily at their posts: collecting dog saliva, cutting rabbits, injecting rabbits...

The development of the rabies vaccine was progressing orderly, without any decisive results yet.

Garrett took a round, checked and guided the operations. Then he pulled out a hound that was kept separately and began his experiment for the day.

This experimental dog with patent arterial duct had survived continuously for a week without abnormalities. Garrett skillfully restrained it, used a calming spell to bind and alleviate pain, prepared the skin on the right lower limb, and the chest...

Systemic heparinization was impossible. He held a dry leech in his hand, cast an anticoagulant spell, and swept over the dog from head to toe. Then, a small snake leaped out and entered the dog’s body.

Right heart catheterization was out of the question, so he substituted it with an echocardiogram.

Anteroposterior and lateral imaging of the aortic arch, observed through the eyes of the Spirit of the Covenant.

After confirming everything was correct through several twists and turns, he made an incision in the right femoral vein and inserted a vine, growing it along the path of blood return to the heart—

The small snake

swam parallel within the limbs of the experimental dog. The Spirit of the Covenant provided another set of eyes, guiding the vine upward, upward, upward.

Through the femoral vein, inferior vena cava, right atrium, right ventricle, main pulmonary artery, to the ductus arteriosus between the aorta and pulmonary artery, he probed into the descending aorta, quickly retracted, turned to the side, and nestled at the junction of the ductus and descending aorta...

A dim white light, carrying silver threads from the tip of the vine, guided the growth of the blood vessels inward, slowly sealing into a circle. In the phantom view of the snake, the blood originally diverted from the aorta to the pulmonary artery with each heartbeat, became less and less, until not a drop was left.

Good!

He retracted the vine, retracted the silver threads, and landed at the junction of the ductus and pulmonary artery, guiding the blood vessels to grow once more!

The surgery was already a success at this point. Garrett breathed out, slightly pulled back the silver threads, and placed his fingertips on the dog’s chest, initiating the ultrasound magic.

Under the echocardiogram, the blood ejected from the left atrium flowed out, not a drop entering the pulmonary artery.

Perfect!

He withdrew the vine, withdrew the guiding energy’s silver threads!

He cast a healing spell, healed the femoral vein incision, and returned the experimental dog to its cage. Then he checked the dogs that had undergone surgery before. Indeed, the one that had surgery seven days ago lay listlessly, looking very unwell.

Garrett took a deep breath, cast a [Mechanical Mind] on himself, and started a communication spell. In an instant, intense fear and pain, like a tidal wave, surged toward him:

"It hurts, it hurts!"

"My chest hurts so much!"

"I can barely breathe..."

Garrett remained expressionless. Thankfully, [Mechanical Mind] protected him, allowing him to receive the information without being overwhelmed by the insane emotions. He disconnected, and once again summoned the small snake:

[Go in and take a look—]

Damn, a thrombus!

Alright, introducing the vine and silver threads into the blood vessels did indeed stimulate the coagulation mechanism, likely causing the thrombus. Garrett turned and briskly recorded: The use of leeches for [Systemic Heparinization] needed to be intensified to prevent thrombus formation...

So, what to do about the thrombus that had already formed?

Before entering the lab, the idea of treating heart attack patients flashed through Garrett’s mind. Good, heart attacks also require thrombolysis and thrombectomy, and here was a thrombus-laden experimental dog, perfect for a trial?

His fingertips glowed dimly white, silently pressing down:

[Remove Disease]!
