As the surgeon's assistant, personally feeling the change in power was completely different from watching the live broadcast of the surgery.
The change in power coming from the guide wire and every change in direction became three-dimensional and vivid in his mind. The live broadcast of the surgery could not feel this at all.
This was the feeling! That was right! This was the feeling of breaking through the limits of human beings and finding the turbulence!
Dr. Mehar could not help but be excited.
He seemed to have forgotten that he was a patient lying on the operating table and the guide wire was swimming in his blood vessels.
This kind of excitement and agitation intertwined. Dr. Mehar's heart rate involuntarily began to increase.
"Stop," Zheng Ren, who had been paying attention to the ECG monitor, suddenly said.
"Uh …" Dr. Mehar was stunned. The surgery was going smoothly. Why did he have to stop it?
"Doctor, your heart rate is already 102 beats per minute. If you can't control your emotions, I'll let my assistant replace you, "Zheng Ren said lightly.
"Okay, let me calm down." Dr. Mehar closed his eyes and took a deep breath. Then, he said, "Zheng, that feeling just now was really wonderful. It was the same feeling I imagined, perfect and flawless. Next, can I operate it? "
"Yes, but don't get excited," Zheng Ren said.
Dr. Mehar did not expect Zheng Ren to be so easy to talk to. He really said yes!
His heart rate was a little fast, but after all, he had touched the most difficult part of interventional surgery. It was impossible not to be excited at all.
Although it was only for a moment, he felt the feeling that he had dreamed of for so many years.
Turbulence, the unpredictable force that had the greatest impact on interventional surgery. Zheng could actually make a judgment on the spot and control the guide wire to pass through the turbulence! Moreover, it seemed that there was more than one place. The operation after the turbulence was a little complicated. Dr. Mehar could not completely sense it.
It was really hands that had been kissed by God. Otherwise, there was no way to explain this. He could actually control the guide wire to pass through the turbulence. If he had not experienced it himself, he would never have believed it.
Dr. Mehar quickly calmed down. The various hormone levels in his body decreased and his heart rate gradually returned to normal.
His ability to manage his own emotions was superb.
Perhaps it was because he was a big shot in the field of cardiology, coupled with his own heart disease, it was the result of years of subtle control.
"Zheng, I can give it a try." Dr. Mehar silently counted his heartbeats and finally opened his eyes to speak to Zheng Ren.
"There's no need to understand the medical physics formula. The data is too complicated, and it's impossible to calculate and get the correct method in an instant. You have to rely on your feelings, Dr. Mehar, "Zheng Ren said.
Dr. Mehar smiled, indicating that he knew.
After all, lying on the operating table, he couldn't do anything else even if he wanted to.
The guide wire continued to swim in the radial artery. Dr. Mehar could feel that Zheng, who was in the surgeon's position, had reduced the strength of his hand. At this moment, he became an assistant.
The surgeon was himself, the patient lying on the operating table.
Dr. Mehar twisted the micro-guide wire with his right hand and looked at the screen above. The micro-guide wire moved forward bit by bit.
It was almost inevitable for the guide wire and micro-guide wire to touch the blood vessel wall during interventional surgery.
The unpredictable turbulence, the surgeon's technique, and the blood vessels that were not much thicker than the micro-guide wire were all obstacles.
For Dr. Mehar, however, only turbulence was real and insurmountable. His right hand twisted the micro-guide wire slightly, feeling the insignificant force coming from it.
Here … In an instant, Dr. Mehar felt the power of the turbulence in his blood vessels. However, he only had time to make the first move. Then, the micro-guide wire was hit by the turbulence and hit the blood vessel wall.
"Dr. Mehar, press your wrist down and move your finger 6 ° to the fourth quadrant. This position can go over. But after you go over, your wrist has to move to the upper left … "Zheng Ren corrected.
The micro-guide wire was still in the radial artery. It was not a big deal to touch the blood vessel wall. Dr. Mehar knew this.
"Zheng, how did you react? Foresight or … "
"I've done a lot of surgeries. After feeling the power of the turbulence, the body's natural reaction," Zheng Ren said. "Doctor, we need to speed up the surgery. You still have three chances to try."
Only three chances left? Dr. Mehar felt a little regretful.
However, Zheng Ren was right. He was now in the state of surgery. He was already an old man in his eighties. It was impossible for him to have a lot of time to squander.
He held his breath and focused, controlling the micro-guide wire to continue moving forward.
Unfortunately, although Dr. Mehar could feel the existence of the turbulence, his body's reaction could not be compared to the young Zheng Ren's.
Every time he wanted to react, the blood flow in the blood vessels would cause the micro-guide wire to deviate and hit the blood vessel wall.
The last time, it even gently touched an arteriosclerotic plaque.
Dr. Mehar sighed. This experience was very poor. It was better for Zheng Ren to operate it. He simply felt the feeling of passing through the turbulence.
There was no way he could reverse the aging of his body's functions.
"Zheng, you should do it," Dr. Mehar said with some regret. "As an assistant, I don't think I should take up too much of the surgeon's resources."
Zheng Ren smiled and did not criticize Dr. Mehar. He nodded and said, "Doctor, continue the surgery."
The control of the micro-guide wire changed from Dr. Mehar to Zheng Ren. It was as if an uncontrollable beast had been directly tamed.
It advanced in the blood vessel wall.
When it encountered the turbulence again, Dr. Mehar looked at the image. His hand holding the micro-guide wire felt the slight change in strength and angle.
So that was it …
So that was it …
So that was it …
Constant enlightenment rose in Dr. Mehar's heart.
At this moment, he was no longer excited. It was like when he first came into contact with the discipline of interventional surgery. He felt, experienced, and improved.
The guide wire was about to enter the anterior descending branch when Zheng Ren suddenly raised his head and gave Lao He a look.
Lao He held the medicine in his hand and directly pushed it in.
Basic anesthesia referred to the method of putting the patient in a deep sleep or in a light state of anesthesia. It was usually used for short-term operations, such as gastroenteroscopy, painless abortion …
After Zheng Ren tried many times, the continuous failure made him lose patience.
It would be better to let the doctor be anesthetized. That was why Lao He appeared here.
The doctor felt that something was wrong and immediately said, "Zheng …"
He only said one word before he fell asleep.
Zheng Ren seized the time to perform the surgery. The time for basic anesthesia was very short. If the surgery could not be completed in 15 minutes, he would have to continue giving the medicine. If that was the case, the risk would increase exponentially.
"Boss Zheng, is this a good idea?" Lao He held the syringe in his hand and was a little terrified.
"There's nothing wrong with it," Zheng Ren said. "Su Yun, what are you looking at? Capture device."
Su Yun immediately went to the side and acted as an assistant.
In his imagination, the scene of Zheng Ren making continuous mistakes because of the huge pressure did not happen. Everything was the same as the previous surgeries. It was simple, clean, and neat.
'What a pity.' Such a thought surfaced in Su Yun's mind.
This kind of wooden person was really boring. So what if he gave himself a chance! Su Yun thought to himself.
However, the surgery continued, and after Dr. Mehar was anesthetized, it instantly sped up. Su Yun could not multitask. It was not enough even if he went all out to be an assistant.
Lao He also noticed the increase in the speed of the surgery. It turned out that Boss Zheng was teaching Dr. Mehar a surgery class just now … However, the speed of the surgery just now was already very fast. Did it have to be so fast?
The guide wire accurately hit the capture device, and the non-compliant balloon expanded inward. This series of steps was completed in one go.
"Su Yun, pay attention to the monitor." As Zheng Ren operated the catheter to perform the blunt dissection, he said cautiously, "If there's anything wrong, tell the matron to give the medicine according to your judgment."
Although the data displayed on the monitor showed that the patient's physical condition was stable, the most dangerous step was to remove the stent in the anterior descending branch immediately.
"Okay, I'm watching." Su Yun was not surprised that Zheng Ren had left everything to him. He was only responsible for the surgery.
After all, he was considered a professional among professionals when it came to heart complications.
"Boss Zheng, this surgery of yours …" Chief Zhang Lin looked at the interventional cardiologist who had been avoiding the removal of the coronary stent and said in shock, "It's really … amazing!"
Zheng Ren did not say anything. So what if he boasted? If he could not perform the surgery, wouldn't he just become a fool?
Chief Zhang Lin did not notice that Zheng Ren had ignored her. She did not feel embarrassed at all.
She was so focused on watching the surgery that she forgot everything else. She did not take the 'praise' just now seriously at all. It was just that it was the truth and she would not be happy if she did not spit it out.
A stent extractor was inserted.
It was like a catheter with a blunt head at the front. It tried to cut off the adhesion and proliferation between the intima of the blood vessel and the stent with the least amount of force.
Zheng Ren was the most familiar with this kind of operation.
This was the principle of soft tofu being made by touch. However, his hand could not go in now. He could only use interventional surgery to dissociate the adhesion between the stent and the intima of the blood vessel.
The difficulty of the surgery suddenly increased.
The coronary stent extraction technique had appeared a long time ago but was immediately rejected. This was because the success rate of the surgery … was almost zero. In the end, it was better to start developing biodegradable stents than doctors who were willing to touch this field.
Zheng Ren, who crossed the field of surgery and interventional surgery, did not have such troubles.
He removed the catheter with both hands and inserted it into Dr. Mehar's anterior descending coronary artery.
A small black shadow appeared on the screen. It was very small and very thin. It was impossible to tell if one did not look carefully.
Chief Zhang Lin looked at the screen carefully and felt that the catheter had rotated at an angle. The guide wire seemed to be walking in her coronary artery, and her heart skipped a beat.
The catheter did not hesitate to walk toward the black shadow. The image of the thrombosis being pulled appeared in Chief Zhang Lin's mind. This was the most difficult part. The blood vessels should have spasms, followed by myocardial ischemia, and then …
Chief Zhang Lin immediately realized that anesthesia was the right thing to do.
She could not help but think of this as an observer. If Dr. Mehar was still awake, his coronary artery would have already begun to spasm.
