As the surgeon's assistant, experiencing this change of power in person is completely different from watching the live broadcast of the surgery.
The changes in force and direction on the guide wire became three-dimensional and concrete in his mind. You can't feel this at all during the live broadcast of the surgery.
That's what it feels like! That’s absolutely right! This is the kind of operating feel that breaks through the limits of human beings and finds turbulence!
Dr. Mehar couldn't help but get excited.
He seemed to have forgotten that he was a patient, lying on the operating table while the guide wire was traveling in his blood vessels.
This excitement and excitement were intertwined, and Dr. Mehar's heart rate began to accelerate involuntarily.
"Stop." Zheng Ren, who had been paying attention to the ECG monitoring, suddenly said.
"Uh..." Dr. Mehar was startled for a moment. The operation went smoothly. Why did he stop
"Doctor, your heart rate is already 102 beats/minute. If you can't control your emotions anymore, I will ask my assistant to replace you." Zheng Ren said calmly.
"Okay, let me calm down." Dr. Mehar closed his eyes, took a deep breath, and then said: "Zheng, the feeling just now was really wonderful, just like the feeling I imagined, perfect. Next, can I operate it?"
"Okay, but don't get excited." Zheng Ren said.
Dr. Mehar didn't expect Zheng Ren to be so easy to talk to. He really said "yes" to himself!
The heart rate is a bit fast, but after all, I have touched the most difficult point of the interventional surgery. It is impossible not to be excited at all.
Although it was only for a moment, he felt the feeling he had dreamed of for so many years.
Turbulence is the unpredictable force that has the greatest impact on interventional surgery. Zheng was able to make on-the-spot judgments and control the guidewire to pass through the turbulence! And it seems that there is more than one place. The operation after the turbulence is a bit complicated, and Dr. Mehar cannot completely perceive it clearly.
They are really hands kissed by God, otherwise it is impossible to explain this. It is actually possible to control the guide wire to penetrate the turbulent flow. If you had not experienced it yourself, you would never believe it.
Dr. Mehar quickly calmed down, the levels of various hormones released by his body dropped, and his heart rate gradually returned to normal.
His ability to manage his emotions is superb.
Perhaps because he is a master in the field of cardiology, and he also has heart disease, it is the result of subtle control over the years.
"Zheng, I can give it a try." Dr. Mehar silently counted his heartbeat, and finally opened his eyes and said to Zheng Ren.
"There is no need to understand the formulas of medical physics. The data is too complex and it is impossible to calculate it instantly and get a correct method. You have to rely on your feelings, Dr. Mehar." Zheng Ren said.
Dr. Mehar smiled and indicated that he knew.
After all, lying on the operating table, I couldn't do any other movements I wanted to do.
The guidewire continued to swim in the radial artery, and Dr. Mehar could feel that Zheng, who was at the surgeon's position, was using less force on his hand. At this moment, he became an assistant.
The surgeon is himself, the patient lying on the operating table.
Dr. Mehar twisted the microguidewire with his right hand and looked at the screen above. The microguidewire moved forward little by little.
It is almost inevitable in interventional surgery that guidewires and microguidewires will touch the blood vessel wall.
Unpredictable turbulence when it will occur, the operator's technique, and blood vessels that are not much thicker than a microguidewire are all obstacles.
But for Dr. Mehar, only turbulence is real and insurmountable. His right hand slightly twisted the micro guide wire, feeling the insignificant force coming from the guide wire.
Here... For a moment, Dr. Mehar felt the power of turbulence in his blood vessels. However, he only had time to make the first movement, and then the microguidewire was deflected by the turbulence and hit the blood vessel wall.
"Dr. Mehar, press your wrist down and move your fingers 6° to the fourth quadrant. You can pass this position. But after passing it, your wrist will move to the upper left..." Zheng Ren corrected.
The microguidewire was still in the radial artery, so it was okay to touch the vessel wall. Dr. Mehar knew this.
"Zheng, how did you react? Prediction or..."
"We have done a lot of surgeries, and our body will react naturally after feeling the force of turbulence." Zheng Ren said, "Doctor, we need to speed up the surgery. You still have three chances to try."
Only 3 chances? Dr. Mehar had some regrets.
But Zheng Ren was right. He was currently undergoing surgery and he was already over 80 years old. It was impossible for him to have a lot of time for himself to squander.
He held his breath and concentrated, controlled the micro guidewire and continued to move forward.
It's a pity that although Dr. Mehar can feel the existence of turbulence, his body's reaction is completely incomparable to that of young Zheng Ren.
Whenever he wants to react, the blood flow in the blood vessel deflects the microguidewire and hits the blood vessel wall.
The last time, I even lightly touched an arteriosclerotic plaque.
Dr. Mehar lamented that the experience was poor. It's not as if Zheng Ren is operating, and he is simply feeling the feeling of penetrating the turbulent flow.
There is no way to reverse the aging of body functions.
"Zheng, you better do it." Dr. Mehar said with some regret: "As an assistant, I think I shouldn't take up too many magician resources."
Zheng Ren smiled and did not slander Dr. Mehar. He nodded and said, "Doctor, continue the operation."
The control of the microguidewire was switched from Dr. Mehar to Zheng Ren, as if an uncontrollable beast had been tamed.
Advance within the blood vessel wall.
When encountering turbulence again, Dr. Mehar looked at the image and felt the weak changes in strength and angle with his hand holding the micro guidewire.
That’s how it turns out…
That’s how it turns out…
That’s how it turns out…
Continuous realizations arose in Dr. Mehar's mind.
At this time, he was no longer excited, just like when he first came into contact with interventional subjects, he was feeling, experiencing, and improving.
As the guidewire was about to enter the anterior descending branch, Zheng Ren suddenly raised his head and gave Lao He a look.
Lao He held the medicine in his hand and injected it directly.
Basic anesthesia refers to a method that puts the patient in a state of deep sleep or light anesthesia. Generally used for short-term operations, such as gastroenteroscopy, painless abortion...
After Zheng Ren tried many times, his constant failures made him impatient.
It might be better to let the doctor be anesthetized, which is why Lao He appears here.
The doctor felt something was wrong and immediately said: "Zheng..."
After saying just one word, he fell asleep.
Zheng Ren took the time to operate. The basic anesthesia lasted only a short time. If the operation could not be completed in 15 minutes, the drug would have to be continued. In that case, the risk increases exponentially.
"Boss Zheng, is this okay?" Lao He held the syringe in his hand, a little scared.
"There's nothing wrong with it." Zheng Ren said, "Su Yun, what are you looking at? A catching device."
Su Yun immediately stepped aside and acted as an assistant.
The scene where he imagined that Zheng Ren would make continuous mistakes due to the huge pressure did not happen. Everything was the same as previous surgeries, simple, clean and neat.
What a pity, Su Yun had such a thought in his mind.
This kind of wooden person is really boring, so what if you give yourself a chance! Su Yun thought in his heart.
But the operation continued, and it sped up instantly after Dr. Mehar was given basic anesthesia. Su Yun couldn't do two things at once, and even working as an assistant with all his strength was not enough.
Lao He also noticed that the speed of surgery had increased. It turned out that Boss Zheng was giving Dr. Mehar a surgical lesson just now... But the speed of the surgery just now was already very fast. Does it have to be so fast
The guide wire accurately hits the catcher and the non-compliant balloon is expanded in one go.
"Su Yun, pay attention to the monitor." Zheng Ren said cautiously while operating the catheter for blunt separation: "As long as something is wrong, tell the head nurse to administer the drug according to your judgment."
Although the data displayed on the monitor now shows that the physical condition is stable, the stent in the anterior descending artery needs to be removed immediately, which is the most dangerous step.
"Well, I'm watching." Su Yun was not surprised that Zheng Ren left everything to himself. He was only responsible for the surgery.
After all, when it comes to cardiac complications, I am considered a professional among professionals.
"Boss Zheng, what you did during this operation..." Director Zhang Lin watched the interventional cardiologist avoid removing the coronary stent during the operation, and said in astonishment: "It's really... amazing!"
Zheng Ren didn't say anything. How could he boast more highly? If you can't do the surgery, don't you just become a fool
Director Zhang Lin didn't notice that Zheng Ren ignored her, and she didn't feel embarrassed at all.
She concentrated on watching the operation process, completely forgetting herself. She didn't mean the "compliment" just now, it was just the fact that she wouldn't be happy if she didn't complain.
A stent extractor was inserted.
It is like a catheter with a blunt tip in front, trying to cut off the adhesion and proliferation between the vascular intima and the stent with the minimum force.
Zheng Ren is the most skilled at this kind of operation.
This is the principle of making tender tofu by touching it. But now he can't get his hand in, so he can only use interventional surgery to free the adhesion between the stent and the lining of the blood vessel.
The difficulty of the operation suddenly increased.
Coronary stent removal was a procedure that appeared very early, but was immediately rejected. Because the success rate of surgery... is almost zero. So much so that in the end, they would rather start developing biodegradable stents, and no doctor would be willing to touch this field.
Zheng Ren, who works in the surgery and interventional departments, does not have this trouble.
He used both hands to remove the catheter and enter Dr. Mehar's anterior descending coronary artery.
A small group of dark shadows appears in the picture. It is so small and thin that it is impossible to distinguish it without looking carefully.
Director Zhang Lin looked at the screen carefully and felt that the catheter rotated at an angle. The guide wire seemed to be walking in her coronary arteries, and her heart skipped a beat.
The catheter walked towards the black shadow without hesitation, and the image of the blood clot being stretched appeared in Director Zhang Lin's mind. This is the most difficult part. The blood vessels should spasm, followed by myocardial ischemia, and then...
Anesthesia is the answer, Director Zhang Lin realized immediately.
As a spectator, I can't help but have this association. If Dr. Mehar is still awake, I am afraid that the coronary artery will have begun to spasm at this time.
