Then came the most critical moment.

"Syringe One!"

Zhao Heng said to Tian Zhen, who was standing next to him.

"Okay."

Tian Zhen responded, and quickly handed the syringe to Zhao Heng's hand, this tacit understanding was as if it had been cooperated many times.

Zhao Heng took the syringe, selected the right angle, and slowly pierced the skin at an angle of 45 degrees, and soon, the topical anesthetic was slowly injected.

Next, wait for the anesthesia to take effect before performing the puncture.

The local anaesthesia is fully effective and usually does not take more than five minutes at most.

Soon, four minutes later, Zhao Heng nodded to Tian Zhen.

Tian Zhen understood, leaned down, leaned over to the old man's ear, and asked softly, "Old man, does it hurt now?" ”

"Pain? It doesn't hurt. ”

The old man felt that the position of his waist seemed to become numb, and it didn't hurt at all, so he said very realistically.

Originally, he thought that this surgical "experiment" would be very painful, and he was ready to grit his teeth and hold on.

As a veteran who has experienced the removal of bullets without anesthesia on the battlefield, the tolerance of the elderly to pain is beyond the imagination of ordinary people.

"Has the experiment begun?"

The old man asked again.

"Well, here we go."

Tian Zhen nodded and said.

"Why doesn't it hurt?"

The old man asked directly.

He also thought that this "experiment" must be very painful.

"It doesn't hurt because I'm anesthetized."

Tian Zhen said patiently.

Hearing this, the old man also nodded slightly, closed his eyes and said nothing.

Looks like the time will come.

The old man couldn't help but think in his heart.

At this time, he began to recall the years of his life and war.

"Dr. Zhao, it's okay."

Tian Zhen nodded to Zhao Heng and said.

"Okay, needle."

Zhao Heng said again.

Tian Zhen quickly handed the puncture needle that he had already held in his hand to Zhao Heng's hand.

After receiving the puncture needle, Zhao Heng held his breath and concentrated, went through it again in his mind, and determined the location.

In this position, the tumor mass that has invaded the cristae can be avoided and the puncture needle can be accurately delivered into the medullary cavity.

The reason why cancer makes everyone talk about "cancer" is because of the infinite proliferation and metastasis of cancer cells.

Transferring to the spine invades the spinal nerve, causing intense pain like a knife.

What Zhao Heng has to do now is to directly insert the catheter into the medullary cavity, and then directly give analgesics through a microcomputer pump to suppress this inhuman pain.

Speaking of which, this kind of treatment actually has a wide range of applications, and many neurogenic pains cannot be inhibited by oral medications.

Laugh at!

Zhao Heng held the puncture needle in his hand, and without any hesitation, he exerted a very subtle force downward, and the puncture needle penetrated the skin and muscles and directly entered the medullary cavity.

The process is lightning fast, very fast and accurate.

It can be said that so many preparations have been made just for such a sudden.

In clinical practice, especially on the operating table, the ultimate goal of many surgeries is to complete the "all at once".

This is even more evident in various interventional procedures.

Among them, peripheral vascular intervention and cardiovascular intervention, in particular, require such speed and precision.

Just think about it, when doing interventional treatment, operate a slender catheter to pass through the major important blood vessels of the human body and accurately find the parts that need to be treated.

What is required is that the surgeon has strong spatial imagination and fine operation ability.

Inside the teaching room.

"Good!"

Seeing that Zhao Heng had completed the piercing almost instantly, Liu Shangming couldn't help but shout hello.

Liu Shangming is knowledgeable, he knows that without absolute confidence and a grasp of the patient's body anatomy and the strength of his own shot, Zhao Heng's puncture action will never be so neat and neat.

On the operating table, you can see whether a doctor's level is high or not, just look at his movements.

The more skilled the doctor, the more clean and pleasing his operation looks.

"This time, at least twenty years of skill."

Li Haiyang also said in amazement.

Of course, twenty years is just a virtual finger, Zhao Heng is only twenty-five years old, where is the twenty-year practice time.

Two and a half years at most.

In the operating room, after Zhao Heng completed the puncture, the catheter was implanted into the medullary cavity through the puncture cannula, and the fixation was quickly completed, and the microcomputer pump was connected.

As the microcomputer pump is activated, the analgesic medication is released from the microcomputer pump little by little, and it enters the medullary cavity directly through the catheter.

At this point, the operation is considered a perfect completion.

Although the operation time is not long, a lot of preparation is required before the operation, and with the physical condition of the elderly, a second puncture is not allowed at all, so it must be completed at one time.

As the analgesic drugs entered the medullary cavity little by little, the severe pain caused by the tumor mass invading the spinal medullary nerve in the elderly was also instantly relieved.

Hey?

Why doesn't it hurt?

The old man, who was lying on the operating table, closed his eyes and waited for the more intense pain to come, suddenly felt that the knife-like pain that tortured him day and night suddenly disappeared at this moment.

This feeling of comfort is simply indescribable.

The old man even felt that he was twenty years younger in an instant.

The old man opened his eyes with some doubts, seeing that Zhao Heng and Tian Zhen were both looking at him with smiles, the old man asked with some doubts: "What about the experiment?" How am I still alive? ”

"Old man, the experiment was successful, you survived."

Zhao Heng couldn't bear to debunk the old man's imagination and said gently.

"Well, that's good, that's good. Your experiment has worked so well that I don't have any pain. ”

The old man nodded, relieved of satisfaction, and said.

In his heart, he must also think that he has made a great contribution.

Seeing the old man's satisfied appearance, Zhao Heng couldn't help but wipe two handfuls of sweat in his heart.

It's not easy to be a doctor, and you have to learn acting.

Zhao Heng thought in his heart.

Next, the old man was sent back to the ward to rest, and Zhao Heng also came out of the operating room.

This time, Director Liu, Li Haiyang, and the doctors from the oncology department came out of the classroom and walked towards Zhao Heng.

"Xiao Zhao, the operation was very successful, and this can be used as a model for the pain treatment of advanced cancer patients." ”

Liu Shangming opened his mouth and said, his evaluation was very high.

"Director Liu, you have a good reputation."

Zhao Heng said modestly.

Liu Shangming, a big old person, is not something that Zhao Heng can sit on an equal footing, or in other words, for a long time, Zhao Heng basically can't reach Liu Shangming's level.

This Liu Shangming is not only the director of the oncology department of Dongfang Hospital, but also a professor of the School of Liberal Arts, and he holds patents worth tens of millions or even hundreds of millions of dollars.

"You are very good, there is still a lot of potential for development in the implantation of neuraxial analgesia."

Liu Shangming said again.

With his vision, of course, he can see the advantages of neuraxial analgesia implantation.

This neuraxial implantation, intrathecal drugs directly act on the central morphine receptor to exert a central analgesic effect, and the effect is more obvious;

Moreover, the patient's medication is significantly reduced, and the intrathecal drug only needs 1/300 of the oral medication, which greatly reduces the side effects caused by the patient's oral painkiller drugs.

According to the latest cancer report released by the National Cancer Center, the number of new cancer patients in the past year has reached as many as 4 million.

That's an average of 10,000 people diagnosed with cancer every day.

Among them, especially liver cancer and lung cancer, 60-70% of patients are already in the middle and advanced stages when they are diagnosed.

"Well, from the current point of view, the development potential of neuraxial analgesia is indeed very large."

Zhao Heng nodded and said.

"Haiyang, in the future, our oncology department must strengthen cooperation with the anesthesiology department, and this aspect will be handed over to you in the future."

Liu Shangming looked at Zhao Heng, then at Li Haiyang and said.

"Okay, Director."

Li Haiyang nodded in response, and smiled at Zhao Heng.

It's all in plain sight.

Doctor: I'm picking up properties at the hospital.
