Doctor: I picked up attributes in the hospital

Chapter 97 The First Appearance of Magical Skills
The next day.

nine in the morning.

operating room.

What was about to be performed at the moment was a craniotomy for female Internet celebrities, and Wen Shen and Zhao Heng performed the preoperative anesthesia together.

Originally, for surgery, the chief surgeon would have to wait until the anesthesia was finished before entering the operating room, but today, the chief surgeon Liu Ziang rarely appeared in the operating room ahead of time, because he was so curious about Zhao Heng.

Liu Ziang wanted to see to what extent the technique of "perioperative brain function and consciousness recovery" in Zhao Heng's hands had reached.

If Zhao Heng's technique can reach the level that Liu Ziang wants, then Liu Ziang will be able to perform surgery on several patients in his hands.

In the final analysis, surgery is a comprehensive job that requires the cooperation of many aspects. The chief surgeon is only the most important part of an operation.

But now, Wen Shen has completed the routine anesthesia part, and the next step is up to Zhao Heng.

Whether the patient can wake up and regain consciousness after the operation depends on what Zhao Heng did during the operation.

"Xiao Zhao, it's up to you next."

Wen Shen said to Zhao Heng very solemnly.

Originally, the technology that Zhao Heng learned from Huang Lao was very cutting-edge. If Zhao Heng hadn't been involved, with his aptitude, even if he studied with Huang Lao every day, without three to five years of study and practice, he would still be able to use it. Don't even think about mastering such a difficult technique.

"Ah."

Zhao Heng nodded and looked at the patient lying on the bed. At this moment, her scalp was covered with electrodes. These electrodes were connected to an EEG, which could monitor the patient's brain electrophysiological activity in real time.

"Is the brain cell nutrition drug ready?"

Zhao Heng turned around and said to Xu Manni, the equipment nurse who cooperated with this operation.

Speaking of which, although Xu Manni is an equipment nurse, she rarely runs into surgery with Zhao Heng.

The main reason is that Zhao Heng's current anesthesia work is basically "booked" by various departments.

Now, the surgeons in the entire Dongfang Hospital wanted to find Zhao Heng for surgical anesthesia, which led to the fact that Zhao Heng's surgical anesthesia for the next three days was basically reserved by surgeons from various departments.

But this is not surprising, Zhao Heng has a good level and good communication skills. The most important thing is that with Huang Lao and Gao Jun's experience in fusion, Zhao Heng is familiar with all kinds of difficult situations in surgical anesthesia. can handle.

Of course, in addition to this, every time he cooperates with the operation, the chief surgeon can drop some skills more or less, and the skill experience happens to be related to the operation.

After integrating these skills and experience, Zhao Heng became more familiar with how to operate, and he could better understand the thinking and even habits of the surgeon. Such cooperation is seamless.

Therefore, in the hearts of all the surgeons in Dongfang Hospital, Zhao Heng is already a well-deserved "gold medal assistant"!

"Ah."

Xu Manni nodded.

For Xu Manni, cooperating with Zhao Heng now is completely different from the feeling before.

"The amount of citicoline and piracetam was adjusted to one-half of the normal value, and the amount of ganglioside and serotonin was adjusted to [-] times the normal value."

Zhao Heng kept giving orders.

And Xu Manni is also constantly adjusting the dosage of the brain cell medicine.

During this period, Zhao Heng was staring at the EEG waveform on the EEG machine.

"Xiao Zhao, what are you looking for?"

Seeing that Zhao Heng had been watching the EEG waveform on the screen, Wen Shen couldn't help asking with some doubts.

The brain is very mysterious and complex. Wen Shen, as a doctor, naturally understands the EEG waveform, but he has no experience in deeper things.

"I'm afraid Dr. Zhao is looking for a special EEG waveform. Under this EEG waveform, the brain will be in a special state to be activated, am I right?"

On the other hand, Liu Zi'ang, who was standing aside, saw some clues. He was originally a brain surgeon, and he was very familiar with EEG waveforms.

He has only heard of the pending activation state that Liu Ziang mentioned.

"Yes, only in this state can the damage to the brain caused by anesthesia and surgery be minimized."

Zhao Heng nodded and said.

"In this way, the application of these brain cell drugs is to induce this special state?"

Liu Ziang asked again.

"Yes, the patient's current brain wave is in a delta wave with a frequency of 1 Hz and an amplitude of 40 μV. In this case, it is difficult for the patient to wake up after surgery.

Therefore, it is necessary to adjust the delta wave of the patient to 3Hz and the amplitude to above 100μV to ensure that the patient can wake up normally after surgery. "

Zhao Heng briefly talked about what he was doing.

However, let’s talk about it, but the combination of drugs to adjust the frequency and amplitude of brain waves is rarely used clinically, at least in China.

Even if some medical institutions are researching this technology, they are only adjusting it on normal people, and the difficulty of adjusting it on patients during surgery increases exponentially.

When Zhao Heng said this, everyone in the operating room felt a sense of ignorance.

"Well, when I was studying abroad, I heard that the Merlin Clinic was researching such a project. I didn't expect to see it with my own eyes now."

Liu Ziang nodded and said with some emotion.

After a while, Zhao Heng saw that the EEG waveform had changed, basically meeting expectations, so Zhao Heng said to Liu Ziang, "Senior, the operation is ready."

"It needs to be adjusted after the operation. Now it is in a state of activation. After the operation, it must be adjusted to alpha waves, so that the patient can fully wake up."

Liu Ziang nodded and asked Zhao Heng again.

"Yes."

Zhao Heng answered in the affirmative.

"This difficulty really breaks through the sky..."

Liu Ziang said with a sigh.

Speaking of this, I have to introduce the band division of brain waves.

Brain waves can be divided into four bands, namely δ (delta) waves, which can be recorded when people are in infancy and immature mentally, and adults are in extreme fatigue, drowsiness or anesthesia;

Theta (theta) wave, which is more obvious in adults with frustration, depression and mental illness;

Alpha (alpha) wave, which is the brain wave of normal people, the rhythm is most obvious when awake, quiet and eyes closed;
The last one is the β (beta) wave, which has the highest frequency and only appears when mental tension and emotional excitement are stimulated.

What Zhao Heng has to do is to adjust the patient's δ wave to α wave after the operation, and to go through θ wave in the middle. The difficulty of this is self-evident.

Wen Shen also nodded. In daily anesthesia work, it is often necessary to adjust the patient's breathing, heart rate, blood pressure and various indicators due to surgical needs.

But tuning brainwaves?

He really hadn't seen it with his own eyes.
