Chapter 1022: Experiment

Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation

Zheng Ren had seen some of the medical records before. Because of Mayo’s cover-up, he did not see any stent surgery or removal surgery for renal artery stenosis.

However, in the subsequent email communication, the Mayo Clinic’s research team also admitted this point. However, they only sent over the procedure of the stent surgery, but the removal process and the patient’s condition were missing.

This was the first time Zheng Ren saw this.

The surgery removed the stent that had narrowed the renal artery. There was nothing interesting to see during the entire surgery. Zheng Ren mainly looked at the changes in the patient’s physical condition after the stent was removed.

After the stent was removed, the patient’s blood pressure became unstable. In order to avoid the changes in blood pressure caused by emotional fluctuations, he used a sedative state and a ventilator to assist in breathing.

He basically used all kinds of rescue drugs. He took turns using the pressors and antihypertensive drugs. Finally, five days later, the patient’s condition was restored to the pre-operation level.

However, the blood pressure before the operation was particularly high. After such a long time, it was restored to the pre-operation state. The operation could be said to have failed.

This was also the reason why the research team kept this a secret. That was what Zheng Ren guessed.

“Boss, I don’t think there’s any problem with these stents,” Rudolf Wagner said.

“Well, I guess the radiofrequency ablation must have caused abnormal physiological changes in the renal artery and the renal sympathetic nerve. That’s why this happened,” Zheng Ren said. “If you go into the stents and suppress the renal sympathetic nerve for a long time, there will definitely be a problem.”

The Professor was stunned.

Where did the judgment of fusion come from? He rubbed his eyes and carefully looked at the imaging examination. He could only see the convergence of fiber lines, but he could not discern the fusion of the renal sympathetic nerve and the renal artery.

However, Professor Rudolf Wagner was already used to following Zheng Ren’s diagnosis. He did not continue to speak, but followed Zheng Ren all the way.

Meanwhile, Professor Danilo Acosta ran out to make a phone call when Zheng Ren began to read the information.

He was working at nine o’clock. He was not sure if this Chinese doctor was going to perform the surgery early in the morning.

Moreover, there was still some related work that needed to be done before the surgery. Danilo really did not like Zheng Ren. It was as if all the trouble was caused by Zheng Ren.

Zheng Ren looked at the radiographic films and had a comprehensive understanding of the disease.

Because he had done anatomical work in the operating theater of the System, Zheng Ren had the most comprehensive understanding of the entire disease.

The others, even the top professors and doctors in the Mayo Clinic, could only make guesses.

This was Zheng Ren’s unique advantage.

The first surgery performed by the Mayo Clinic was almost as perfect as a textbook. It was accurate and delicate.

However, this kind of precision was only in the conventional sense. Zheng Ren suddenly had a thought and entered the System space.

After selecting the time for the surgical training, the operating theater of the System rose from the ground and Zheng Ren began the surgery.

Zheng Ren wanted to perform the surgery. It was not a usual surgery, but a radiofrequency ablation.

Of course, it was not a normal radiofrequency ablation. Zheng Ren directly treated the experimental cadavers as real cadavers and began to dissect them. He also performed radiofrequency ablation with the naked eye.

Radiofrequency was a high-frequency vibration with a frequency of 150,000 times per second.

The human body mainly relied on the movement of ions to conduct electric current. Under the effect of high-frequency alternating current, the direction of change of ion concentration varied with the direction of electric current in a positive and negative half-cycle.

Under the high-frequency oscillation, the ions rubbed against each other and collided with other particles, resulting in bio-thermal effects.

The first radiofrequency ablation was applied to patients with arrhythmia. Later, it was found that the tumor had poor heat dissipation, which made the temperature of the tumor tissue higher than that of the adjacent normal tissue. In addition, the cancer cells were highly sensitive to heat, so the high heat could kill the cancer cells, but the side effects did not occur.

Therefore, radiofrequency ablation was also used for the treatment of tumors. The effect was equivalent to surgical resection.

Zheng Ren’s third interventional surgery for liver cancer performed on Zheng Yunxia at Sea City General Hospital used the method of radiofrequency ablation.

The surgery was very successful. Zheng Yunxia still did not find any signs of recurrence in the tumor tissue after the surgery. The effect was almost the same as surgical resection.

‘Such a consequence must have occurred during the surgery for renal sympathetic nerve radiofrequency ablation to treat renal-derived hypertension. The frequency of radiofrequency ablation must be wrong,’ Zheng Ren guessed.

He would know once he gave it a try.

After all, he had finished the surgery for Zou Jiahua, so he still had a lot of time to train for the surgery.

In fact, Zheng Ren was very curious about the unknown. He was especially curious about the medical unknown.

He knew that completing such a treatment might mean that tens of thousands or hundreds of thousands of patients would be treated. The key was that this kind of ‘experiment’ would not consume a lot of time for the surgery training.

Now, onto the simulation mannequin…

Under the direct gaze of simulation mannequin, Zheng Ren began to radiofrequency ablation of the initial segment of the sympathetic nerve in the kidney of the experimental subject.

The frequency of radiofrequency ablation of tumor tissue was generally around 460 khz. Radiofrequency ablation of the heart was usually around 200 khz to 750 khz depending on the patient’s own condition and illness.

The frequency used by the Mayo Clinic was 510 khz. This could not be considered a mistake.

Zheng Ren estimated that this was not the first patient to receive radiofrequency ablation of the kidney. There was a theoretical basis for the frequency used.

However, there was a problem with this theoretical basis.

He guessed that if the surgery was successful, the frequency should be lower than 510 khz.

Therefore, Zheng Ren began to do experiments, constantly changing the frequency of various radio frequencies to achieve his goal.

In the end, when the radio frequency reached 185 khz, the effect was the most ideal.

Compared to the frequency of the Mayo Clinic Research Group, the difference was more than double. Moreover, the frequency had already exceeded the frequency of normal medical radio frequency, which was slightly lower.

Even so, this was a fact. It was the result of an objective experiment.

Although this experiment was now meaningless to Zheng Ren, he had always wanted to know why.

Moreover, Zheng Ren had only found how to safely use radiofrequency to ‘cut off’ the renal sympathetic nerves; however, he did not know how the patient in front of him, who had been melted by high-frequency radiofrequency needles and solidified the renal sympathetic nerves, reintegrated with the renal artery.

If he were to study this in detail, he might not even have enough time for a year of surgical training.

After Zheng Ren got the answer he wanted, he came out of the operating theater of the System.

“Then that’s it,” Zheng Ren said after he finished reading all the medical records.

“Surgery?” Su Yun asked.

“Yes,” Zheng Ren said. “The surgery has a high probability of solving the problem. Let’s do it.”

Professor Danilo Acosta looked at Zheng Ren as if he was looking at an idiot. In his opinion, this kind of surgery was done blindfolded. There was no chance of success at all.

The young Chinese doctor in front of him would only act as a scapegoat for the failure of the experiment.
