Chapter 403: The vine exits the heart—oh, it didn’t exit!
"What? What stuck in the heart?"
The Necromancer hurriedly put his head over and stared hard, but couldn't see anything. Miss Silver Dragon lowered her voice and said "Shh":
"[Detect Magic]! See for yourself!"
"ah……!"
Leon let out a low exclamation. In the vision of meditation, among the thick and light shadows, a long line snaked like a snake, going up from the junction of the rabbit's right leg and torso, all the way to the heart.
Gretel squinted his eyes and looked at the vine inserted into the rabbit's heart in his meditation field of vision, filled with emotion.
In the two years since he left Heartland City, he has not forgotten that cabin, Uncle Karen who took care of him when he was growing up, and Aunt Eileen who stayed up late to change his clothes.
Moreover, he will never forget little sister Avril Lavigne, who suffered from patent ductus arteriosus, was born weak, and had cyanosis on her fingernails.
When he boarded Archmage Carlisle's airship and flew to the parliament headquarters, he secretly said to himself——
Give me eight years. Sister Avril has ten years at most, so eight years, preferably within five years, I will find a way to safely perform interventional surgery!
To achieve this goal, it is not possible to stay in Heartland City and immerse yourself in running a small clinic. It is not possible to stay in Nevis City and immerse yourself in experiments in the mage tower. To improve the mage level, you need both magic and divine skills, medical magic, and medicine.
At the same time, there must be enough patients for research and development...
Two years of hard work and two years of research. From a first-level mage to a fourth-level mage, Grete has already gone halfway through the road of interventional therapy:
Ultrasound magic, done!
Penicillin research and development completed!
Chloramphenicol, streptomycin, tetracycline and other antibiotics are under development!
The vine birthing technique is completed, and a wave of proficiency has been refreshed on the dwarves!
Syringe manufacturing, completed!
Use silver wire to guide the healing power at fixed points, complete!
Local anesthesia magic, completed!
Next, as long as the vines can be successfully sent into the heart, the treatment can be guided under X-ray and ultrasound, and the sealing operation can be performed... Of course, there are still a lot, a lot, a lot to successfully complete the seal.
Experiments to be done...
Grete narrowed his eyes subconsciously. Although guiding the vines uses mental power, observing the position of the vines (and the marked silver wires) uses [Detection Magic] to project feedback in the meditation field of vision, neither of which is used.
Eyes. However, it seems that only this action can make him see more clearly:
The sinoatrial node above the right atrium ignites the fire of life. The atrium contracts, the mitral and tricuspid valves relax, and blood is squeezed into the ventricle;
On the ventricular wall, the most powerful muscles of the heart are stimulated to contract by the electrical signals sent by the sinoatrial node, sending out the most powerful contraction. At the same time, the aortic valve opens, and the arterial blood carrying rich oxygen is powerfully
The pressure is pumped into the aorta, and the vine that has been wandering tentatively in the aortic arch raises its head and goes 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, unable to advance or retreat;
After going through a cycle of relaxation-diastitation-atrial contraction-ventricular contraction again, the vines contract and retreat sharply!
Oops, I didn’t exit!
The normal heart rate of a rabbit is 180 to 250 beats per minute. During this period, the ventricular systole—that is, the time it takes the heart to pump blood to the aorta—according to the way the human heart operates, is about 3/8 of the cardiac cycle.
.In other words, he has to complete the operation of pulling out the vines within 0.125 seconds...
Don’t panic. Even if it gets stuck in the middle of the aortic valve and you don’t have time to pull it out, the rabbit will not die. Dr. Forsman, the pioneer of cardiac catheterization technology, inserted the catheter into the right atrium.
, and also took an X-ray. There was plenty of time.
No wonder the boss chose to insert the left median cubital vein into the right atrium... The catheter enters the right atrium from the superior vena cava, there is no valve, and it is smooth and silky!
try again!
try again!
OK, it worked!
Grete let out a breath of air. It must be said that manipulating vines is easier than manipulating a guide wire. It only requires concentration. As for the guide wire, the guide wire with a diameter of 1 mm travels in the blood vessel, entering 30 cm, 40 cm, 1 meter, and turning.
, crossing the fork all depends on the doctor’s skill.
Imagine that you are one meter away, in the midst of turbulent blood flow, shaking a 1 mm thick guidewire. Let it turn 30 degrees, 60 degrees, and the tip moves 1.5 mm left/right/up/down.
, enter a certain bifurcation, go deep into the lower blood vessels...
Anyway, Grete had always admired the big guys in the vascular department in his previous life.
He held the vine seeds with the thumb, index finger, and middle finger of his right hand, manipulated the vine to exit, and pulled the silver wire to move it backwards. Clamping the silver wire was only troublesome, as it had to be pulled out bit by bit. If only the vine was used, the spell would be canceled directly.
The vines will disappear...
Gee, how do you develop a vine that can develop within the body? You have to ask your mentor later, or ask Elder Wood?
Grete pondered and thought, but his hands were not slow at all. The vines wrapped around the silver wire and came to near the entrance of the femoral artery, but instead of withdrawing immediately, they turned around and went down to the popliteal artery. The vines suddenly lifted up,
There was a "bite" on the wall of the popliteal artery.
Grete's fingers have been put on it with glycerin. Under the magic of B-ultrasound, you can see that near the blood vessel wall, the image is blurred, like a mosaic. Well, the blood vessel wall is ruptured and blood is flowing out. The desired effect
Achieved, ready for treatment!
He immediately activated the healing technique, followed the silver thread up, and gathered a small ball of light at the wound location to stop the bleeding and heal the blood vessel wall...
Under visual inspection, it can be seen that the injured area no longer continues to bulge, and the blurred area under the B-ultrasound magic no longer expands. Very good, the treatment from the inside of the blood vessel was successful. Next, we will see if there will be any sequelae!
Grete held his breath and carefully continued to manipulate the vine to exit. Until the tip of the silver wire left the rabbit's femoral artery, Grete threw out a treatment technique, couldn't wait to take out the microscope, and directly hit the silver wire onto the stage.
thrombus!
thrombus!
How many clots will be produced if the silver wire travels in the body for such a long time? In the previous life, interventional surgery, whether it was interventional examination or interventional treatment, required heparin anticoagulation!
Not to mention, if a treatment is performed inside a blood vessel, how many clots will be hanging on it? Will it form a thrombus and affect the patient's life safety?
Alas, interventional surgeries without heparin sodium are always hectic...
Fortunately, there is only one silver wire. Unlike the guide wire in the previous life, which looks to be 1 mm in diameter, it is a double-layer structure with a steel core inside and a layer of spring coils tightly wound around the outside. The surface area of the silver wire is so much smaller.
, the blood coagulation caused should be much less... right?
"Gretel, why are you inserting vines into its heart?"
