Since ancient times, there have been many excellent doctors who have devoted themselves to anesthesia.

In order to help the patient resist the pain and carry out the surgery smoothly, they tried all kinds of methods.

According to historical records, before Hua Tuo, Bian Que in the Warring States Period had successfully put the patient down with a kind of "poisonous wine" and completed the first operation.

A copy of "Fifty-two Prescriptions" was unearthed in the Mawangdui Han Tomb, and the anesthetic recorded on it was a kind of wine with aconitum added.

Jin Huangfu's "Acupuncture A and B Sutra" also has a record of acupuncture and moxibustion for pain relief.

Sun Simiao's "Preparation for Emergencies" and Li Shizhen's "Compendium of Materia Medica" also introduced the anesthetic effect of mandala flowers.

However, these are only in the embryonic state, and neither the timeliness nor the safety of anesthesia can be compared with modern anesthetic drugs.

As for freezing limbs with ice and losing consciousness, or tightening limbs with straps to numb limbs, these side ways cannot be counted as anesthesia.

"Do you understand?" Ji picked up the main points and finished speaking, and asked Xin Ziqi.

Xinzi period was slightly hesitant.

"There are some places that I don't know too much...... What I understand is that there is a medicine that can make the patient lose sensation locally or generally, so as to help the patient get through the operation painlessly, comfortably and safely...... Is that what it means? ”

Ji nodded. It's hard to understand this in a short period of time.

"Since you're good at it, then," Xin Ziqi's pale face shone brightly, "do you have this medicine?" ”

"This ......" season is embarrassed.

How to tell him that clinical anesthesia requires more than just anesthetics.

Solid basic theories and professional knowledge, proficient operating methods and techniques, and rich clinical experience are just the basics.

On top of this, sophisticated anesthesia equipment is also needed to carry out careful monitoring and treatment.

For example, when a patient is under anesthesia, use a blood pressure monitor, electrocardiogram, respirator, monitor, etc., to closely monitor the fluctuations of blood pressure, heart rate, blood oxygen saturation, and even brain waves.

These vital signs help the anesthesiologist determine the depth of anesthesia, so that he can take the next step in a timely and effective manner with the help of the anesthesia machine.

Moreover, clinical anesthesia is not all about putting the patient down, it is also divided into general anesthesia and local anesthesia.

Below, there are different subdivisions.

According to this, anesthetics include local anesthetics, general anesthetics, anesthetic-related analgesics and muscle relaxants, etc.

The use of these drugs is not as simple as oral or topical application, but also depends on the type of surgery, the age and constitution of the patient, etc., and the choice of whether to administer intravenous anesthesia with liquid or inhalation anesthesia with gas.

Ji now has neither instruments nor drugs except for empty theories, just like a clever woman without rice, except for staring, what she can do is really limited.

"So, your master didn't teach you how to make this medicine?"

Ji shook his head.

Xin Ziqi's heart, which had just floated to the clouds, fell heavily in the blink of an eye.

It's hard to put into words.

But Ji really can't help it.

Her specialty is clinical, not pharmacy.

Although I later studied Chinese medicine because of my interest, I also knew that Chinese medicine such as toad, goldenrod, menthol, asaroxin, Chuanwu, and Caowu all have anesthetic effects.

But it's a pity that she understands the Chinese medicine anesthesia tightly and doesn't focus on it.

Because since Hua Tuo, the breakthrough of traditional Chinese medicine in anesthesia is really limited, and the achievements are also limited.

It has been lost in the long history for too long, and even though it originated early, it was still overtaken by the latecomers who anesthetized the rapid development of Western medicine.

Western medicine anesthesia is easy to use, long-lasting, safe and reliable, but it is cumbersome to operate and has strict requirements for drug dosage.

If the dosage is insufficient, it will not have a good anesthetic effect. If you overdose, it will have adverse effects on the brain and nervous system.

Traditional Chinese medicine anesthesia is relatively much safer, but there are also many drawbacks.

For example, the depth of anesthesia is not enough, and the muscle relaxation is not complete, and the desired effect is often not achieved.

But right now, there's no better choice.

"By the way, the last time I went to Yidetang, in addition to gypsum, I remember asking you to help me find a few medicinal herbs, have you made it up?"

Xin Ziqi's mind was obviously still hanging on the anesthetic, and he pointed casually: "It's all together, it's in another small bag." ”

Ji opened the cloth bag he was referring to.

Grass black, toad crisp, Sichuan black, Aracea, Yakuza turtle...... That's right.

This is a prescription she once saw in a rare ancient book, called Sleep Shengsan.

Xin Ziqi finally realized something: "Could it be that these medicinal materials are?" ”

Ji nodded, which was a tacit acquiescence.

It can stimulate the sensory nerve endings of the skin and mucous membranes, making it itchy and hot, and then inhibiting it and showing an anesthetic and analgesic effect.

Aracea directly acts on the central nervous system, which can make patients less active, quiet, and reflexive, significantly prolong sleep time, and at the same time has strong pain relief.

The narcotic ingredient contained in toad crisp has a slower onset than decaine, but it is long-lasting, 30 to 60 times greater than cocaine, and has no stimulating effect.

Despite this, her expression was not so optimistic.

"To be honest, I've never used this recipe in the clinic, so there's no guarantee of its effectiveness, but its side effects are known......"

The anesthetic prepared by these herbs is regarded as a general anesthetic after a person drinks it and falls into a coma directly.

When the anesthetic reaches the bloodstream, the drugs that affect the brain flow through other blood vessels and organs, which are also affected.

If the patient's heart rhythm, blood pressure, respiration rate and oxygen saturation cannot be accurately observed, and the response cannot be adjusted in time, the consequences are often uncontrollable and can only be followed.

It has been recorded in the book that some doctors have treated patients with this agent, and the final effect, only two out of ten cases have fully recovered, and the rest are either slow to move, or speech or brain damage, and the sequelae are obvious.

In the case of no certainty, rashly use it on the homeless, but I am afraid that I will not be able to save people, but will become a victim.

"Perhaps, we can try it on some animals first......"

"It's not an idea, but the homeless's injury can't be delayed, and if it is delayed any longer, it will really be useless. Even if you barely pick it up, you will be left with a disability. ”

Xin Ziqi pondered for a moment and reproposed.

"Instead of worrying about this, let's ask the patient himself. Perhaps he is willing to take the risk, after all, in the eyes of some, it is not difficult to choose which is more important than paralysis when it comes to slow movement and blocked speech. Not to mention...... Haven't there been success stories too? ”

The odds of success are too small, and the risks are too great.

However, Xin Ziqi is right, you should still listen to the opinions of the homeless.

His own life, up to him.
