Dressed as a big boss Bai Yueguang, God does not allow salted fish to lie down

The next step is also the most critical step!

It is necessary to enter the human trial phase, the purpose of the trial is to determine whether the drug is effective on humans.

The liquid made from raw datura powder and purified with 100% pure alcohol, Su Yuejian calls this anesthetic.

She thought of two ways, one by inhalation and the other by topical administration.

Since the efficacy of the drug has not yet been proven in humans, it cannot be tested on patients.

There were no rescue equipment or medicines here, and she didn't dare to administer the experimental anesthetic directly intravenously.

Local anesthesia only acts on a local area and leaves other parts unaffected, while systemic intravenous anesthesia will act on the nervous system, respiratory system, circulatory system, etc., and has a relatively greater impact on the patient.

Shen Yuxin wanted to sign up, but was rejected by Su Yuejian.

There are so many young people, and it is not yet the turn of someone as old as the master to try the medicine.

The progress of medicine is based on sacrifices, like Shennong who tasted hundreds of herbs and tested medicines on himself and was poisoned three times a day; like the cadaver teachers, the silent mentors; like the experimental mice, rabbits, and beagles.

Su Yuejian actually thought about conducting the experiment herself, but she was the only one here who had the ability to rescue.

And she has to host the experimental project and record every reaction. Among all the people here, she is the only one who has seen and used anesthetics and knows what the reaction to an anesthetic overdose is like.

Shen Nanxing immediately signed up to be the first to conduct the human inhalation anesthesia experiment.

Su Yuejian adjusted the dosage according to the person's weight, but after all, rabbits are different from humans, and their tolerance to medication varies.

Su Yuejian soaked a towel in the newly-made anesthetic and asked Shen Nanxing to inhale the volatile substance vigorously. Since it was his first time using it, Shen Nanxing took forty deep breaths, and then quickly fell into a coma and lost response to the outside world.

When doing anesthesia experiments, the sphygmomanometer was tied on, and Su Yuejian kept an eye on the blood pressure at all times.

Oh no, my blood pressure has been dropping, my pulse is dropping, and my breathing is tending to be suppressed! "Baiji, go get my first aid kit!"

Su Yuejian directly gave artificial respiration. Facing Shen Nanxing, she tilted his head and raised his chin, pinched his nose, covered his mouth with hers, and blew air into it. Shen Nanxing still had spontaneous breathing, but the frequency was slow, so what Su Yuejian had to do was to assist with artificial respiration to provide ventilation compensation.

Slowly, heart rate and blood pressure increased.

Su Yuejian breathed a sigh of relief!

Bai Ji ran all the way to get the first aid kit, sweating profusely, but Su Yuejian said, "It's not needed anymore."

Bai Ji thought Shen Nanxing was beyond saving, so he rushed to see him. Seeing how anxious he was, Su Yuejian said, "He's fine, don't touch him!"

This time the anesthesia lasted for a full fifty minutes, and it was the effect of general anesthesia.

Inhalation anesthesia, the anesthetic is carried into the lungs along with gas and oxygen. The advantage of this is that it takes effect very quickly.

The disadvantage is that there is no very precise concentration monitoring, and the amount of inhalation is controlled only by experience, so precise anesthesia cannot be performed. Moreover, the patient wakes up quickly after the operation and the pain recovers quickly.

When Shen Nanxing woke up, his mind went blank. His eyes widened with curiosity and confusion. Then he said woodenly, "You are my wife? How come you are so beautiful?"

Everyone burst into laughter.

Su Yuejian was also amused, which showed that anesthetic drugs had an inhibitory effect on the central nervous system, and the brain might not have fully returned to normal when the effects wore off.

This also indirectly proves that the new anesthetic is effective.

The rest of the crowd also joined in the fun, saying with a smile that Master Su was going to become a master's wife.

When Shen Yuxin saw his grandson's silly look, he didn't realize how dangerous the situation was that he had just experienced. Alas, as a doctor, one must have the determination to devote himself to medicine.

As for the rest, the road ahead is long and arduous!

Shen Yuxin patted the confused Shen Nanxing.

Shen Nanxing's human general anesthesia experiment took effect in 40 seconds and lasted for 50 minutes. This is truly a significant breakthrough!

But Su Yuejian was not satisfied. Shen Nanxing briefly experienced respiratory depression, so she needed to recalculate the dosage of anesthetic and the user's height and weight.

Once again, an ordinary medical practitioner signed up. Su Yuejian adjusted the number of inhalations according to his height and weight and conducted the inhalation experiment again.

The doctor quickly fell into a coma, his heart rate and blood pressure were within normal range. The anesthetic took effect in 7 seconds, lasted for 40 minutes, and had no adverse reactions.

After Shen Nanxing woke up, he immediately learned from Bai Ji that Su Yuejian had given him artificial respiration, and he even vividly imitated what he said when he just woke up.

Shen Nanxing has been secretly in love with Su Yuejian for a long time. Su Yuejian actually gave him artificial respiration, but he didn't notice it. When the anesthesia just wore off, he actually said such nonsense. I don't know what Su Su will think of him.

The next day, Su Yuejian went to the clinic as usual and took the opportunity to see if Shen Nanxing had any other sequelae.

Early in the morning, when Shen Nanxing saw Su Yuejian coming in, her face turned red, she turned around, and ran away in one go.

Su Yuejian grabbed him and pressed him down on the stool, "Don't move, I'll check you again."

Su Yuejian also pulled a stool over and sat down, using a stethoscope to listen to Shen Nanxing's heart. She first listened to the lungs and found nothing wrong.

Listening to the heart again, "It's beating a little fast!"

Shen Nanxing thought, how could it not be fast? You have your hand on my chest.

Su Yuejian took Shen Nanxing's blood pressure again, "It's still a little high."

Su Yuejian frowned in thought, Shen Nanxing just looked at Su Yuejian, looking at her mouth, where he had been given artificial respiration yesterday...

When Su Yuejian looked at Shen Nanxing again, she saw his unnatural expression and his ears were red...

This time Su Yuejian reacted, it turned out that this junior brother was seduced? !

That's why my heart rate and blood pressure are a little abnormal.

Ugh! She was so scared that she thought there was some side effect of the anesthesia!

Although Shen Nanxing is very pleasing to the eye, I have a heavy responsibility as a sister, so I'd better not harm such a handsome boy from a good family.

"I, ..." Shen Nanxing was about to open his mouth when suddenly a series of hurried calls interrupted Su Yuejian's thoughts and also interrupted Shen Nanxing's subsequent words.

"Sister, sister, I signed up for a human experiment, the one with local wounds. Look at my leg injury, it hurts so much, give me some anesthetic quickly."

Baiji kept crying and asking for anesthetic.

Su Yue saw that the blood was still flowing from Baiji's leg and the wound was neat, and it was obvious that he had cut it with a knife.

How could this silly child have the heart to do this?

For a moment, Su Yuejian was a little annoyed, but seeing that he wanted to do his best for the anesthetic issue, she felt distressed!

It’s okay. I already know the importance of disinfection, and I also know to treat the area with an alcohol cotton ball before taking action.

The wound is a bit deep and needs to be sutured and local anesthesia is required. This wound cannot be numbed by applying an anesthetic. The anesthetic needs to be drawn out with a syringe and then infiltrated layer by layer, from the subcutaneous layer to the muscle layer, along the trauma site, to perform the corresponding local anesthesia operation.

While operating, Su Yuejian explained the steps and purpose to the medical student who was learning next to her.

First clean the wound of Bletilla striata with normal saline, and then inject local anesthetic layer by layer.

Thanks to the glass syringe in the specially made first aid kit, I complained at the time, who would use such syringes now.

Now that I think about it, thank God for the help. There is actually only one reusable instrument in the first aid kit, but it has to be sterilized by high temperature boiling after each use.

After waiting for a minute after the local anesthesia was infiltrated, Su Yuejian touched the edge of the wound, but Baiji didn't even feel her touch.

Then Su Yuejian started to suture and then bandage the wound. The whole debridement and suture process took about fifteen minutes.

Su Yuejian calculated the time from the time the anesthetic was injected. About thirty minutes later, Bai Ji said that he felt pain in the wound, which meant that the anesthetic had worn off.

Baiji used self-mutilation to conduct a human local anesthesia experiment. The results showed that it took one minute for the injection of local anesthesia to take effect and lasted for about 30 minutes. This effect is still very good.

Su Yuejian officially announced, "The anesthetic experiment was successful!"
