It's not that hard to open a hospital in another world, right?

Chapter 407 The vine quits the heart - oops, didn't quit!

"What? What stuck in the heart?"

The necromancer hastily poked his head over, his eyes widened desperately, but he couldn't see anything.Miss Yinlong lowered her voice and let out a "hush":
"[Detect Magic]! See for yourself!"

"what……!"

Leon let out a low exclamation.In the meditation field of vision, in the thick and faint shadows, a long line winds like a snake, going up from the junction of the rabbit's right leg and torso, all the way to the heart.

Gretel narrowed his eyes, looking at the vine inserted into the rabbit's heart in the meditation vision, filled with emotion.

In the two years since he left Hartland City, he never forgot that hut, forgot to take care of Uncle Karen who grew up in his original body, and forgot Aunt Irene who stayed up late to turn on the lamp and changed his clothes.

Moreover, he will never forget little sister Avril, who suffers from a patent ductus arteriosus, is congenitally weak, and has cyanosis on her nails.

When he boarded the airship of Archmage Carlisle and flew to the headquarters of the parliament, he once secretly said to himself——

Give me eight years.Sister Avril still has ten years at most, then eight years, preferably within five years, I want to find a safe way to perform interventional surgery!

To achieve this goal, it is not enough to stay in Hartland City and concentrate on running a small clinic.Staying in Nevis City and immersing yourself in experiments in the mage's tower will not work.To increase the level of mages, to cultivate both magic and divine arts, to develop medical magic and medicine at the same time, to have enough patients...

Two years of hard work, two years of study.From a first-level little mage to an advanced fourth-level mage, Gretel has already gone halfway on the road of interventional therapy:
Ultrasonic magic, done!
Penicillin research and development, completed!

Chloramphenicol, streptomycin, tetracycline and other antibiotics are under development!

Vine spawning technique, completed, brushed a wave of proficiency on the dwarves!

Syringe manufacturing, complete!

Use the silver thread to guide the healing power at a fixed point, and it's done!

Local anesthesia magic, complete!

Next, as long as the vines can be successfully sent into the heart, the treatment can be guided by X-ray and ultrasound, and the closure operation can be performed... Of course, there are many, many, many more to successfully complete the closure. The experiment to do...

Gretel narrowed his eyes subconsciously.Although spiritual power is used to guide the vines, and to observe the position of the vines (and the marked silver wire) is fed back and projected by [Detect Magic] in the meditation field of view, neither of which uses eyes.However, it seems that only this action can make him see more clearly:
The sinus node above the right atrium ignites the fire of life.The atria contract, the mitral and tricuspid valves relax, and blood is squeezed into the ventricles;

On the walls of the ventricles, the most powerful muscles in the heart are stimulated to contract by electrical signals from the sinoatrial node, sending out a most powerful contraction.At the same time, the aortic valve opens, and the oxygen-rich arterial blood is pumped into the aorta by strong pressure, while the tentative vines that have been wandering in the aortic arch raise their heads and go upstream, directly inserting into the left ventricle;

The ventricular wall relaxes, the aortic valve closes, and the vines and silver wires are caught in the middle of the aortic valve, making it impossible to advance or retreat;

After another cycle of relaxation-diastole-atrial contraction-ventricular contraction, the vine contracts and retreats sharply!

Oops, didn't quit!

The normal heart rate of a rabbit is 180 to 250 beats per minute.During this period, ventricular systole—the time when the heart pumps blood to the aorta—is about 3/8 of the cardiac cycle, according to the way the human heart works.In other words, he has to complete the operation of pulling out the vine within 0.125 seconds...

Don't panic.Even if it is stuck in the middle of the aortic valve for a while, the rabbit will not die if it is not pulled out in time.The big man who pioneered the technique of cardiac catheterization, Dr. Forsman, even took an X-ray after inserting the catheter into the right atrium.There is plenty of time.

No wonder the boss chooses the median vein of the left elbow and inserts it into the right atrium... The catheter enters the right atrium from the superior vena cava, and it is smooth and silky without valves!

try again!
try again!
Ok, it worked!

Gretel let out a breath of air.It must be said that manipulating the vines is still easier than manipulating the guide wire, all it needs is the mind.As for the guide wire, a guide wire with a diameter of 1 mm swims in the blood vessel, and it goes in 30 cm, 40 cm, 1 meter, turns, and crosses the fork, all depending on the doctor's skill.

Imagine that you are separated by a distance of one meter, and in the turbulent blood flow, shake a 1 mm thick guide wire.Let it turn 30 degrees, 60 degrees, move the tip to the left/right/up/down by 1.5 mm, enter a bifurcation, and go deep into the lower blood vessels...

Anyway, in his previous life, Gretel had always admired those big bosses in the vascular department.

He held the vine seeds with the thumb, index finger, and middle finger of his right hand, manipulated the vines to withdraw, and pulled the silver wire to move backward.It's a little troublesome to clamp a silver thread, you have to pull it out bit by bit. If you just use vines, cancel the spell directly, and the vines will disappear...

Tsk, how to develop vines that can develop in the body?Go back and ask your mentor, or, ask Elder Wood?
Gretel deliberated and pondered, but his hands were not slow at all.The vine wrapped around the silver thread and came near the entrance of the femoral artery, but instead of withdrawing immediately, it turned around and went down to the popliteal artery.The vine suddenly lifted up and "bited" the wall of the popliteal artery.

Gretel's fingers were already on it with glycerin. Under the B-ultrasound magic, you can see the vicinity of the blood vessel wall, and the image is blurred, like a mosaic.Well, the blood vessel wall is ruptured, the blood is flowing out, the desired effect has been achieved, and it can be treated!

He immediately activated the healing technique, went up the silver thread, and gathered a small ball of light on the wounded area.Stops bleeding, heals blood vessel walls...

Under the visual state, the wound will no longer continue to bulge, and the blurred part under the B-ultrasound magic will no longer expand.Very good, the treatment from the inside of the blood vessel was successful, and we will see if there will be any sequelae!

Gretel held his breath, cautiously, and continued to manipulate the vine to exit.Until the tip of the silver wire left the rabbit's femoral artery, Gretel casually threw out a healing technique, impatiently took out the microscope, and directly put the silver wire on the stage.

thrombus!
thrombus!
How many blood clots will the silver wire walk in the body for such a long time?Interventional surgery in the previous life, whether it is interventional examination or interventional treatment, must be anticoagulated with heparin!

Not to mention, how many blood clots will hang on the inside of a blood vessel when a healing operation is launched?Will it form a thrombus and affect the life safety of the patient?

Alas, interventional surgery without heparin sodium is always done in a panic...

Fortunately, there is only one silver wire.Unlike the guide wire in the previous life, which looks 1 mm in diameter, it has a double-layer structure, with a steel core inside and a layer of spring coils tightly wrapped around the outside.The surface area of ​​the silver wire is so much smaller, so the coagulation caused by it should be much less... right?

"Grete, what are you doing with vines in its heart?"
