2173 It's so slow that it makes one's hair stand up
Mu Tao stood beside old Wu like he had always done.
In the operating room, boss Zheng started to step on the surgical line.
On the screen, the guide wire moved forward slowly and was placed at the end of the eye artery after a few minutes.
Because the Super-selection process required the patient to be as close to the retinas capillary network as possible, boss Zheng used the thinnest guide wire.
It was thinner than the guide wire used in neurosurgery, and it was the kind of guide wire used for baby interventional surgery.
This kind of guide wire was soft and cotton, so he could not use any strength in it. During the process of superselection, there was a high chance of failure.
However, mu Tao sighed with emotion when he saw that boss Zheng’s micro-wire, although moving slowly, did not make a single mistake or restart the operation.
“Mu Tao, do you know boss Zheng’s hand technique?” Old Wu asked.
“Teacher, it should be about the understanding of the turbulent flow of blood in the blood vessels.” Mu Tao said,”boss Zheng has a deep understanding of turbulence. I think it’s because he’s particularly good at interventional surgeries.”
“Yes.” Old Wu nodded his head.
Overcoming the effects of turbulence was the most profound theory and technique of intervention. Elder Wu had been performing interventional surgeries for half his life, but he only had a vague understanding that if a guide wire or a micro guide wire was inserted into a blood vessel, blood flow would have a huge impact on it.
As for how to overcome it and increase the success rate of the surgery, elder Wu had no idea.
Boss Zheng had already mastered the technique of dealing with turbulence at such a young age, and old Wu was very impressed.
This was a breakthrough on a technical level, but it was difficult to quantify and even more difficult to grasp.
The micro-catheter entered, but it did not go to the limit. Instead, it stopped in the blood vessel and did not touch the walls of the blood vessels around it.
He began to perform angiography. Just as boss Zheng had predicted, a part of the retinas vascular network was blocked, which seriously affected the supply of “nutrients” to the retina by the red blood cells that carried oxygen.
After confirming the condition, the surgery continued. Su Yun connected the end of the catheter to a syringe and began to inject a saline solution with a small amount of contrast agent.
His movements were slow, careful, and delicate.
After the saline solution entered the vascular network of the retina, Su Yun began to increase the pressure slightly.
The “sticky” dye molecule was “pushed” forward by the saline solution injected by the syringe.
Since there was a gap between the catheter and the surrounding blood vessels, Su Yun had been carefully controlling the strength of the saline injection to avoid causing the capillaries to rupture and bleed.
This step required a great deal of patience.
When it was time to be quick, boss Zheng’s surgery was done quickly. When it was time to slow down, boss Zheng wasn’t in a hurry at all. He waited quietly.
Time passed.
After 12 minutes, the location of the blockage began to move. The macromolecules were deformed under the pressure and were “pushed” away bit by bit with the pressure of the capillaries on the wall.
Mu Tao knew that this was the most difficult part of the surgery.
In this place, one had to constantly change their strength in minute ways to make the pressure conform to the elasticity of the blood vessels.
Three minutes later, Su Yun stopped.
Mu Tao pressed the walkie-talkie. He did not say anything and listened to the conversation between Zheng Ren and Su Yun.
“Boss, I can’t take it anymore.” Su Yun admitted defeat, which was rare.”I can’t feel the wall of the tube. If I continue pushing, I think the capillaries will burst.” If the strength is too low, it won’t have any effect. “
“Oh, I’ll do it then.” Zheng Ren took the syringe and said,”it’s the chest compressions done during the liver transplant. Your arm has been strained, right?”
“Old fan gave me some liniment for a few days, and I’m much better. However, you’ll have to wait for a while before you can perform the surgery that’s too detailed. Look at you, the surgery is as slow as you can get. This is a work injury!”
“Oh, okay, it’s an industrial injury.” “Okay,” Zheng Ren replied lightly and did not say anything else.
“Slow down!” Su Yun was still worried as she reminded him.
“It’s fine, I know what to do. ” Zheng Ren replied,”she’s still young, and the retinal capillaries are elastic. I can feel the change in resistance, so I’ll be very careful. Don’t worry.”
“Suya, how much trouble have you caused me?” Su Yun started to nag.
“Brother Yun, I’m sorry.” Xu suya said in a low voice, her voice trembling.
“Don’t talk to the patient,” Zheng Ren said,”the change in airflow during the conversation caused a change in the pressure of the vascular network.”
“So many things.” Su Yun said in disdain,”actually, life is not as difficult as you think. When you encounter a difficult problem, you’ll list out all the solutions, and then you’ll realize that you can’t do anything, so you’ll just give up. “
It was unclear if he was talking to boss Zheng or Xu suya.
Mu Tao was stunned.
“Right, old mu?” Su Yun asked.
“……”
He knew that he was “eavesdropping”, so he was actually talking to him. Mu Tao was speechless.
He was criticizing himself for not performing the surgery well, and he was only criticizing the interventional surgery. Who could guarantee that they could perform the surgery better than boss Zheng? Bullshit!
Not only boss Zheng, but he was probably no match for Su Yun.
Mu Tao smiled and pressed the button on the walkie-talkie again.
If he didn’t want to listen, then he wouldn’t listen.
He looked at the image on the screen. After boss Zheng took over, the overall surgery speed did not seem to be any faster than when Su Yun performed it.
Many black dots were moving around, almost invisible.
However, as time passed, after an hour and 35 minutes, mu Tao pulled up the previous image and did an overlapping process.
This comparison was much simpler and more direct. The movement of black spots at many of the congestion points was still very obvious.
The surgery was going on slowly.
No one spoke. Old Wu and mu Tao waited quietly.
Boss Zheng didn’t seem to be in a hurry. He was extremely patient, carefully feeling the pressure transmitted back from the syringe and adjusting his strength at any time.
The surgery took a total of four hours and twenty-two minutes.
This could be seen from the time it took for the surgeon to open up an incision and how difficult it was to perform compared to the destructive embolism surgery.
When the last black shadow disappeared and the entire retinal capillary network was covered with contrast agent, Mr. Wu’s body “softened” and then he leaned back in his chair.
The blood vessels that were filled with contrast agents were like the roots of plants, transporting sufficient nutrients to the retinas so that the patient could see again.
The surgery could be considered a success. Mu Tao knew that the teacher was too nervous.
The surgery did not seem difficult, as it only required opening up the retinal capillary network. However, those who knew the surgery knew the difficulty of this surgery. If they were not careful, the surgery would fail, and the patient might suffer the damage of permanent blindness.
However, it was only an eye.
“Boss Zheng, do you want to switch hands and rest?” Mu Tao pressed the walkie-talkie and said.
“Su Yun, are you tired?”
“I’m not tired. “
“There’s no need for that. ” Zheng Ren turned around and smiled at mu Tao through the lead glass.
