Doctor: I picked up attributes in the hospital

Chapter 127 The Bright Future of Neuraxial Analgesia
Next, is the most critical moment.

"Syringe No. [-]!"

Zhao Heng said to Tian Zhen who was standing beside him.

"Ok."

Tian Zhen responded, and quickly handed the syringe to Zhao Heng's hand. This kind of tacit understanding seemed to have cooperated many times.

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

The next step is to wait for the anesthesia to take effect before performing the puncture.

Local anesthesia takes full effect and generally takes no more than 5 minutes at most.

Soon, 4 minutes later, Zhao Heng nodded to Tian Zhen.

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

"It hurts? It doesn't hurt."

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

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

As a veteran who has experienced taking bullets without anesthesia on the battlefield, the old man's tolerance for pain is beyond the imagination of ordinary people.

"Has the experiment started?"

the old man asked again.

"Well, it's started."

Tian Zhen nodded and said.

"Why doesn't it hurt?"

the old man asked directly.

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

"It doesn't hurt because of the anesthesia."

Tian Zhen said patiently.

Hearing this, the old man also nodded slightly, and closed his eyes in silence.

It seems that the next time is up.

The old man couldn't help thinking in his heart.

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

"Doctor Zhao, it's all right."

Tian Zhen nodded to Zhao Heng and said.

"Okay, the puncture needle."

Zhao Heng said again.

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

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

This position can avoid the tumor mass that has invaded the spine, and accurately send the puncture needle into the medullary cavity.

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

If it is transferred to the spine, it will invade the spinal nerves and cause severe pain like a knife.

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

Speaking of it, this kind of treatment actually has a wide range of applications. Many neurogenic pains cannot be suppressed by oral drugs.

laugh!
Holding the puncture needle in Zhao Heng's hand, without any hesitation, he exerted a very delicate downward force. The puncture needle penetrated the skin and muscle, and directly entered the medullary cavity.

This process is as fast as lightning, very fast and accurate.

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

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

This point is more obvious in various interventional operations.

Among them, peripheral vascular intervention and cardiovascular intervention especially require such rapidity and precision.

When you think about it, you will know that when doing interventional therapy, the slender catheter is operated to pass through the major blood vessels of the human body to accurately find the part that needs treatment.

What this requires is that the operating doctor has a strong ability of spatial imagination and fine manipulation.

In the classroom.

"it is good!"

Seeing that Zhao Heng completed the puncture almost instantly, Liu Shangming couldn't help saying hello.

Liu Shangming is knowledgeable. He knows that without absolute confidence and grasp of the patient's anatomical structure and the strength of his own hand, Zhao Heng's puncture action would never be so crisp and neat.

On the operating table, you can tell whether a doctor's level is high or not by looking at his movements.

The higher the level of the doctor, the more neat and pleasing his operation looks.

"This time, at least 20 years of skill."

Li Haiyang also said in amazement.

Of course, 20 years is just a false finger, Zhao Heng is only 25 years old, where does the 20 years of practice come from?

Two and a half years at most.

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

As the microcomputer pump started to work, the analgesic drug was released from the microcomputer pump little by little, and directly entered the medullary cavity through the catheter.

At this point, the operation is considered perfect.

Although the operation time is not long, a lot of preparations are required before the operation, and the old man's physical condition does not allow a second puncture at all, so it must be done in one go.

As the analgesic drugs entered the medullary cavity little by little, the severe pain caused by the tumor mass invading the spinal cord nerves in the old man was instantly relieved.

Huh?
Why doesn't it hurt anymore?
The old man who was lying on the operating table with his eyes closed and waiting for the more severe pain he imagined, suddenly felt that the knife-like pain that tortured him day and night suddenly disappeared at this moment.

This feeling of comfort cannot be described in words.

The old man even felt that he was 20 years younger in an instant.

The old man opened his eyes with some doubts, and saw that Zhao Heng and Tian Zhen looked at him with smiles on their faces. The old man asked with some doubts, "What about the experiment? Why am I still alive?"

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

Zhao Heng couldn't bear to expose the old man's imagination, so he said gently.

"Well, that's good, that's good. Your experiment works really well, and I don't even feel pain anymore."

The old man nodded, very satisfied and relieved to speak.

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

Seeing the satisfied look of the old man, Zhao Heng couldn't help but wiped his sweat from his heart.

It is not easy to be a doctor, but also 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 left the operating room.

As soon as he came out, Director Liu, Li Haiyang, and the doctors from the oncology department came out of the demonstration room and walked towards Zhao Heng.

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

Liu Shangming said that his evaluation was very high.

"Director Liu, you are overrated."

Zhao Heng said very modestly.

A big boss like Liu Shangming is not yet equal to Zhao Heng, or in other words, for a long time, Zhao Heng basically cannot 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 Boya Medical College, holding patents worth tens of millions or even hundreds of millions of dollars in his hands.

"You are very good. There is still great potential for development in spinal analgesia implantation."

Liu Shangming said again.

From his perspective, of course, he can see the advantages of spinal analgesia implantation.

This is implanted in the spinal canal, and the intrathecal drug directly acts on the central morphine receptor, exerting the central analgesic effect, and the effect is more obvious;

Moreover, the amount of medication for patients is significantly reduced, and intrathecal medication only needs 1/300 of oral administration, which greatly reduces the side effects caused by oral painkillers.

According to the latest cancer report released by the National Cancer Center, in the last year, the number of new cancer patients has reached as many as 400 million.

In other words, on average, 1 people are diagnosed with cancer every day.

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

"Well, from the current point of view, the development potential of spinal canal analgesia is indeed great."

Zhao Heng nodded and said.

"Hai Hai, in the future, our oncology department must strengthen cooperation with the anesthesiology department. In this regard, I will leave it 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 is more than words.
