Chapter 1022： test

The contents of the medical records, Zheng Ren had seen some before. Because of the concealment of Mayo's side, stent surgery and removal surgery for renal artery stenosis were not seen.

However, in the subsequent mail communication, the Mayo Clinic research team also acknowledged this, but only sent the surgical procedure of the stent surgery, but the removal process and the patient's situation were absent.

This paragraph was the first time Zheng Ren saw it.

Surgery removed the stent of the renal artery stenosis, the whole surgical procedure is nothing to look at, Zheng Ren mainly depends on the changes in the physical state of the patient after removing the stent.

After the stent was removed, the patient developed a state of unstable blood pressure, and because of the need to avoid mood fluctuations leading to changes in blood pressure, a calming state, ventilator assisted breathing, and the like were employed.

Various rescue drugs have been used basically once. The booster and antihypertensive drugs were used in turn, and the patient's condition was restored to the preoperative level after 5 days.

Only the blood pressure before surgery is particularly high. Tossing for so long, returning to the preoperative state, the surgery can be said to have failed.

This is why the research team is ignorant of this, Zheng Ren guessed.

"Boss, this awkward bracket, I see no problem." Professor Rudolf Wagner said.

"Well, I guess it should be caused by radiofrequency ablation that causes abnormal physiological changes in the renal artery and renal sympathetic nerves. This is the case." Zheng Rendao: "Going down to the stent, long-term compression of the renal sympathetic nerves, will definitely Something went wrong."

Professor is amazed.

Where is the judgment of this fusion? He rubbed his eyes and looked at the imaging examination carefully. He could only see the convergence of the fibrous cords, but he could not judge the fusion of the renal sympathetic nerves with the renal artery.

But Professor Rudolf Wagner has become accustomed to following Zheng Ren’s diagnosis. He did not continue to speak, but he followed Zheng Ren’s way.

Professor Danilo Acosta ran out and called when Zheng Ren began to read the information.

Here is 9 o'clock to work, he is not sure whether the Chinese doctor is going to have surgery early.

And there are still some related work to be done before the operation. Danilo really does not like Zheng Ren. It seems that all the troubles are made by Zheng Ren.

Zheng Ren looked at the film and had a comprehensive understanding of the condition.

Because of the anatomical work in the system operating room, Zheng Ren's understanding and cognition of the whole condition is the most comprehensive.

Others, even the world's top professors and doctors at the Mayo Clinic, can only guess.

This is the unique advantage of Zheng Ren.

The first radiotherapy of percutaneous renal sympathetic radiofrequency ablation in the Mayo Clinic is almost perfect, accurate and detailed in textbooks.

But this kind of accuracy and exquisiteness is just the kind in the conventional sense. Zheng Ren suddenly moved into the system space.

Clicking on the training time, the system operating room rose to the ground, and Zheng Ren began surgery.

Zheng Ren is going to have surgery, not surgery, but radiofrequency ablation.

Of course, it is not a normal radiofrequency ablation procedure. Zheng Ren directly regarded the experimental body as a general teacher, began to dissect, and performed radiofrequency ablation under direct vision.

Radio frequency is a high frequency vibration with a frequency of 150,000 times per second.

The human body mainly relies on ions to conduct current. Under the action of high-frequency alternating current, the direction of ion concentration changes with the direction of current to a positive and negative half-cycle.

Under high frequency oscillations, the ions rub against each other and collide with other particles to produce biothermal action.

The earliest radiofrequency ablation was applied to patients with arrhythmia. Later, it was found that the tumor had poor heat dissipation, which caused the tumor tissue temperature to be higher than its neighboring normal tissue. In addition, the cancer cells were sensitive to high heat, and high heat could kill cancer cells without side effects.

Therefore, radiofrequency ablation is also used as a treatment for tumors, and the effect is equivalent to surgical resection.

Zheng Ren’s third intervention in liver cancer for Zheng Yunxia in the first hospital in Haicheng was the use of radiofrequency ablation.

The operation was very successful. After Zheng Yunxia, ​​there was no evidence of recurrence of the tumor tissue. The effect was almost the same as the surgical resection.

In the operation of renal sympathetic radiofrequency ablation for the treatment of renal hypertension, such a consequence has occurred. It is definitely the frequency of radiofrequency ablation. Zheng Ren is so speculative.

I will know if I try it.

Anyway, I have completed surgery for Zou Jiahua, and there are still many training sessions.

In fact, Zheng Ren’s curiosity about the unknown is very heavy, especially the various unknowns in medical treatment.

He knows that completing such a treatment may mean that the diseases of tens of thousands and hundreds of thousands of patients are treated. The key is that this "test" does not consume much surgical training time.

It is only the experimental body that is consumed.

Under direct vision, Zheng Ren began radiofrequency ablation of the initial part of the renal sympathetic nerve of the experimental body.

The frequency of radiofrequency ablation of tumor tissue is generally around 460 kHz. Cardiac radiofrequency ablation, according to the patient's own situation and the condition, the frequency of radio frequency is generally around 200KHz-750KHz.

The frequency taken by the Mayo Clinic is 510KHz, which cannot be said to be a mistake.

Zheng Ren estimates that this is not the first patient to undergo radiofrequency ablation of the kidneys. The frequency of use is theoretically based.

However, it is this theoretical basis that has a problem He guessed that if the operation is successful, this frequency should be smaller than 510KHz.

So Zheng Ren began experimenting and constantly changing the frequency of various radio frequencies to achieve his own goals.

The final RF frequency is 185KHz, the best effect.

This frequency is almost twice as much as the frequency of the Mayo Clinic research group. Moreover, the frequency has exceeded the frequency of normal medical radio frequency, which is slightly lower.

Even so, this is a fact and the result of objective experimentation.

This test is now meaningless to Zheng Ren, but he always wants to know why.

Moreover, Zheng Ren only found out how to safely use the radio frequency method to "cut off" the renal sympathetic nerves, but did not know how the patients in front of the eyes were melted by the high-frequency RF needle, and the solidified renal sympathetic nerves re-fused with the renal artery.

If this is to be studied carefully, I am afraid that there is not enough surgery for one year.

After Zheng Ren got the answer he wanted, he came out of the system operating room.

"That's it." Zheng Ren read all the medical records, and then said.

"Surgery?" Su Yun asked.

“Yeah.” Zheng Rendao, “The big chance of surgery can solve the problem, or do it.”

Professor Danilo Acosta looked at Zheng Ren like an idiot. In his opinion, this kind of surgery is almost blindfolded, and there is no possibility of success.

The young Chinese doctor in front of him will only serve as a scapegoat for the trial failure.
