Chapter 1832

feel? In recent years, Dr. Lerner has vaguely touched the erratic word said by Dr. Charles.

But he didn't know exactly how to do it.

"Wearing sterile gloves will affect the judgment of the operator. Each pair of sterile gloves has a different hand feeling. So I said that sterile gloves are the biggest link affecting surgery."

Dr. Lerner remembered that Dr. Charles did say that.

At that time, I thought the teacher was joking, but I didn't expect it to be true.

"But we must ensure a sterile environment, so the initial stage of the operation is the key for the operator to be familiar with the patient's anatomical structure and clear about the hand feeling." Dr. Charles continued slowly.

In his opinion, the operation in front of him is bound to be a great success.

It's really a pleasure to see this kind of operation, a flawless process. Dr. Charles is a little addicted to it.

Except for themselves and the operators on the operating table, no one can understand the realm of hand feeling. Life is sometimes lonely like snow.

"Everyone's body tissue has unique elasticity and toughness. At the beginning of blunt dissociation, it is the best time for the operator to establish communication with the unique body tissue." Dr. Charles said: "this kind of communication will let the operator know the hand feeling of facing the organs. As long as the communication mode is established and the hand feeling is clear, many complications and mistakes will never occur."

"Look, when Dr. Zheng anastomoses the blood vessels, the strength and angle of the needle tip are the choices made by feeling the information left by the hand feeling of the blood vessels." Dr. Charles said happily, "it's perfect without any defect. Watching this unparalleled operation brings people an inexplicable enjoyment."

Lena was speechless.

Everything Dr. Charles said, he just vaguely realized that it seemed so. However, it is impossible for him to apply it in clinical surgery without 3-5 years of running in.

After 3-5 years, I'm old. Although the experience will be richer, it has passed the peak of surgery.

Some movements, the body has not allowed itself to complete flawlessly.

Dr. Lena has some regrets.

But if it is 3-5 years, it may not be realized after 5 years, and a new 5 years is needed.

It has nothing to do with diligence. To reach this level, we need talent.

"After establishing this connection, as soon as the hand reaches the position of the brachiocephalic artery, we know how much force should be used for anastomosis. Of course, this method of anastomosis should be based on almost perfect microsurgery."

"Perfect match, Lena, this operation has reached the level of my peak period, and even overflow. After the operation, you remember to copy the whole process back and figure it out."

"Although your age has been unable to reach this level, it is still good for the improvement of your surgical level."

Lena silently looked at the surgical image. In the process of the teacher Dr. Charles explaining the "hand feeling", in a few words, the operator had completed the anastomosis of the brachiocephalic artery.

After all three head arm vessels were anastomosed, full flow perfusion was started.

The proximal end of the four branch artificial blood vessel was anastomosed with the distal end of the original ascending aorta artificial blood vessel. After exhaust, Zheng Ren opened the ascending aorta.

After the mixed venous oxygen saturation reaches more than 90%, the heart begins to warm slowly and the heart automatically beats again.

At this time, a row of numbers appear on the screen - perfusion time 110 min, occlusion 95 min, deep hypothermic circulatory arrest selective cerebral perfusion time 84 min.

Perfect!

Flawless!

Dr. Lena looked at these similar figures and he couldn't help but be amazed.

If you do your own surgery, these numbers will basically double. Doubling is not the key. There is absolutely no difference between perfusion time and blocking time.

The small time gap represents one thing - the operator's operation is stable and fast.

Is this all the change brought about by "feel"? Dr. Lena watched the operation in silence.

The operator should have finished the operation, but when he saw the end of hypothermic cardiopulmonary bypass and the heart beat again, another image appeared on the screen.

The interventional guide wire enters the blood vessel, passes through the anastomotic section and starts angiography.

At the same time, the operation field was still clean, only a small amount of blood exuded, but there was no trace of contrast agent.

This is the final confirmation.

Generally, interventional surgery is not used to confirm bleeding after elephant nose surgery, which is not recognized by Dr. Lena.

If the guide wire touches the anastomosis section, it may cause unpredictable changes of the anastomosis.

"Lena, this is an area I have never reached." Dr. Charles suddenly said.

"Teacher, I don't think it's necessary here." Dr. Lena said stubbornly.

"No, just keep looking." Dr. Charles has guessed Zheng Ren's idea. He said with a smile, "the operator has made bold changes to the operation method, which is based on his thorough understanding of the anatomical structure and the state of the patient."

"What is he going to do?"

"You must have forgotten what technique the young man used to win the Nobel Prize."

"..." Lena was speechless.

Is it necessary to show the technique of interventional surgery in this large-scale operation?

This should be a very irresponsible behavior, but why does the teacher expect so?

Suddenly, an idea came to Lena's mind.

Two years ago, the patient underwent coronary artery bypass grafting and ascending aortic valved tube replacement. Nowadays, the replaced blood vessels have also changed under the influence of Marfan syndrome.

This is the terrible part of congenital diseases, and the transplanted blood vessels will also be affected, especially the location of coronary artery bypass established by autologous internal mammary artery.

According to the film and image analysis before operation, Lena believes that there is a small problem in the patient's coronary artery, but it is not worth paying attention to.

With the torn aorta as the background, nothing is worth noting.

And the artist's ambition is so big? What is he going to do? Is it

Lena's guess soon became a reality.

Interventional stent surgery.

Coronary artery... Ascending aorta... Descending aorta

Every blood vessel that may be torn is covered with membranous stent. There is no gap between the stent and the stent, which is perfect and calm.

"He went for an intervention?" Asked Dr. Lena in a trance.

"Yes." Dr. Charles finally changed his posture. It took too long and his body did not adapt. "Marfan syndrome will lead to pathological changes in the middle membrane of the great arteries. It's better to use stents."

Dr. Lena couldn't spit out a puff in his chest.

If the surgery itself is still hopeful to reach the level of the operator, then the current interventional surgery

I can't do it myself.

This is the rolling of the field!
