Doctor: It's reasonable to perform surgery on yourself.

The patient's anesthesia depth was too strong, so many neurophysiological tests during the operation could not be performed.

General anesthesia makes the patient sleep soundly, which is an advantage, but also a disadvantage.

In particular, the impact on the microelectrode in the medial part of the globus pallidus is huge.

Xu Qiu has conducted many simulation experiments before.

It was found that if the simulated patient with Parkinson's disease was set, the measured microelectrode effect was relatively small during general anesthesia.

However, for patients with dystonia, the microelectrode recording decreased significantly.

As we all know, microelectrodes are important parameters of brain pulse devices, which affect the final surgical effect. If the anesthesia method affects this data, the consequences are devastating...

"But why is the data significantly reduced for dystonia?"

Xu Qiu couldn't understand.

He had two guesses.

One is the pathogenic mechanism of dystonia itself.

The other is that the globus pallidus area is highly sensitive, and the impact of general anesthesia drugs on this area is more serious than that on patients with Parkinson's disease.

But it doesn't matter anymore.

Compared with general anesthesia, Xu Qiu has a better way.

Conscious sedation!

This technology is commonly used in dentistry.

As the name implies, the patient maintains a certain degree of sobriety during anesthesia. The role of anesthetic drugs is more to eliminate negative emotions such as pain and anxiety, without causing loss of consciousness.

There are countless advantages, such as no side effects at a safe dose, low risk, etc.

However, whether a qualified conscious sedation can be completed requires consideration of the ability of the surgical team and the anesthesiologist.

After all, individual tolerance and conditions are different. For each patient, the conscious sedation plan may be completely different, which is much more difficult than general anesthesia with eyes rolled.

What made Xu Qiu firmly choose conscious sedation is:

The particularity of the implantation itself!

Since the surgical area is the brain, conscious sedation can detect the patient's brain at any time to prevent the surgeon from accidentally damaging the brain function area without knowing it.

Second, various parameters can be adjusted during the operation according to the patient's brain response!

"First, benzodiazepines can be excluded." Xu Qiu thought.

The choice of drugs for conscious sedation is the first step.

Benzodiazepines interfere strongly with microelectrode data and should not be used unless necessary.

In addition, using propofol alone or in combination with opioid infusion is not a good choice.

This anesthesia combination is more suitable for surgery on the subthalamic nucleus and has almost no effect on the globus pallidus.

Xu Qiu also considered short-acting opioids.

This type of anesthesia has almost no effect on the microelectrode!

But later he found that once the dose was increased, the patient would inevitably develop muscle stiffness.

Chen Zhiyao himself had the problem of dystonia, and then muscle stiffness... that would be a long-lived man hanging himself.

After many dissatisfactions, Xu Qiu has found a new anesthesia plan.

Propofol, short-acting opioids and dexmedetomidine are used together!

Propofol is a commonly used conscious sedative anesthetic, needless to say.

The use of short-acting opioids in small doses will hardly affect the microelectrode.

The same is true for dexmedetomidine. In small doses, it not only does not affect the microelectrode, but also does not cover up the patient's own clinical symptoms, and does not lead to "false relief" brought by anesthetics, causing the operator's misjudgment.

Therefore, Xu Qiu thought of a brand new anesthesia method.

Low-dose opioid fentanyl combined with dexmedetomidine.

Low-dose propofol combined with low-concentration sevoflurane for balanced anesthesia!

"Get ready."

Xu Qiu completed the anesthesia according to the expected ratio.

Half an hour later, the operation was over.

The system's voice also sounded.

"Congratulations, you have completed the deep brain dual-channel pulse generator implantation surgery!"

"Rating: A+!"

"Return all the physical and mental energy consumed during the operation!"

"..."

Finally reached A+!

Xu Qiu was quite surprised.

In many previous attempts, his surgical steps were impeccable, but the highest could only reach A-.

This means that although the surgical operation was fine, the patient's recovery effect was not satisfactory.

The only possibility is the anesthesia method.

After so many adjustments, I finally broke through the A rating barrier!

The only pity is that I didn't get the S rating.

Otherwise, I could get various bonus rewards!

"Can anesthesia be improved again?"

Xu Qiu tried a few more times.

He didn't open his eyes until the next morning.

His expression was a little disappointed.

Unfortunately, he adjusted the combination ratio of anesthetic drugs many times yesterday, but he didn't get an A+ score.

Instead, he returned to A-.

This means that the initial anesthesia plan should be the best ratio.

If he wants to break through to the S rating, he may have to continue to improve the details of the operation.

After returning to the clinic, Xu Qiu wrote down the anesthesia plan and handed it to the anesthesia team.

After the morning clinic, he re-entered the simulated operating room and started a new operation.

"Congratulations, you have completed the deep brain dual-channel pulse generator implantation surgery!"

"Rating: S-!"

"Return all the physical and energy consumption of the operation!"

"You get an additional reward: negative effects of anesthesia -10%!"

Finally!

Xu Qiu suddenly opened his eyes, and a trace of joy flashed in his eyes.

After working on the surgery for several days and nights, the details of the surgery were finally polished to S level with a reasonable anesthesia plan!

Although it is still only S-, it is already eligible for system bonus!

What surprised Xu Qiu was that it was actually an increase in anesthesia.

He was not worried about his surgery.

The damage could be minimized as much as possible.

On the contrary, it was the first time for the anesthesia team to do it, so it was difficult to be perfect.

This time the bonus was for anesthesia, which was like a pillow for a sleepy person.

"Big brother!"

At this time, there was a knock on the door, and at the same time there was a soft and sticky girl's voice.

"Come in."

As soon as Xu Qiu finished speaking, a girl in school uniform came in with a lunch box.

"Shen Ning." Xu Qiu looked up.

At this time, Shen Ning was no longer the thin little girl who lagged behind her peers three years ago.

Three years later, she was eleven years old and had grown tall, 1.56 meters tall, with delicate features and fair skin, as delicate as a porcelain doll.

The biggest change is her personality.

Back then, she looked frightened, like a little animal that had left its nest, but now she exudes a sunny aura from the inside out, generous and confident.

However, what has not changed is her understanding.

"Big brother, my mother asked me to bring you food, and I also fried spicy chicken offal for you. It's appetizing, try it!"

Shen Ning squinted her eyes when she smiled.

Xu Qiu rubbed the little girl's head, pinched her authentic baby face, and asked casually: "Are you ready for the final exam?"

He paused as soon as he asked.

He once didn't understand why the elders always asked such unpopular questions.

Unexpectedly, one day he finally became the person he hated...
