Different people have different concepts of time.

But one thing that is almost uniform for most people is that if you focus on something, time will go so fast that you can't even feel it passing.

Just like John and the other four.

By the time the time came March 26, 1885, the four of them had been busy for almost two months, hardly having a weekend off, either doing real yàn in the real yàn room or discussing problems in the living room of John's house...... John said that the other three people listened in a way that "discussed" the problem.

It was the weekend, and they met again in an empty room at John's house.

"Gentlemen!"

Under the burning gaze of the other three people, John put the two small bottles on the table in the middle of the crowd, and said with a slight smile: "Fortunately, I have just made a little more of the two medicines, and it should be enough to do it." ”

There was a sudden silence in the room.

After staring at the two bottles for a long time, Thomas muttered in a low voice, "John, did you name them?" ”

"One is called procaine, and the other is called lidocaine."

Without hesitation, John said two names that he knew too well from his previous life.

Procaine was relatively simple to prepare, and it took John only two days to get it out of the chemistry room. But lidocaine's words were much more difficult, he searched the memories in his head, and finally saw an article in the corner that he had scanned, and found a way to prepare it.

Thank God again!

Although the reborn John does not have any anti-heaven system, nor does he have a huge knowledge reserve, he also has a super golden finger, that is, as long as he has learned something, it will inevitably be deeply engraved in his mind, even if it is just seen, heard or even glimpsed. As long as you have the patience to recall, you can remember it again!

Otherwise, it would not be easy for him to come up with these things by relying on him as a pure surgeon.

In fact, John originally only planned to make procaine, but considering its shortcomings were too obvious, he finally racked his brains to get lidocaine as well. It took him nearly a month to come up with something like this. Renting a chemical room is a big blood ......

"Gentlemen, let's give it a try!"

After everyone had digested the two weird-sounding names, the anxious Robert stood up and said loudly with a determined expression.

After a moment of silence, Paul and Thomas also stood up, nodding at the same time and saying, "John, come on!" ”

"Good!"

Nodding heavily, John stood up and said, "We have done it many times, and I think everyone has seen the effect." But if you want to actually put them into surgery. We have to test their effects with the human body, and this is unavoidable...... Come on! ”

Everyone's love was instantly excited.

Over the past two weeks, the other three have worked with John on at least twenty animal realizations, tossing the dogs and rabbits worse than death. But after witnessing the extreme effects of these two drug artifacts, they were already a little impatient for human trials!

"Who's coming first?!"

Suddenly filled with pride, Thomas's eyes turned to Paul and Robert.

John is the inventor of the drug and the creator of the lumbar puncture technique, and there is no one more suitable to do it than him. Then the object of the real yàn can only be one of the three of them!

"I'll do it!"

Taking a deep breath, Robert was the first to step up.

There was a mixture of excitement and fear in his eyes. Robert gritted his teeth and said, "Try it on me first, and if it's okay, John, you can do it on the two of them!" ”

Before coming to John's house, Robert had already made up his mind.

Of the four of them, John was the undisputed leader and the center of the whole program, and Thomas was naturally much stronger than him and Paul as a relatively mature surgeon. Worthy of John's first deputy. As for Paul's words, which were patient and perceptive, seemed to be better than Robert in all respects, and were always able to help John a lot, which made him often feel a faint uneasiness in his heart—the most useless uneasiness of all!

Robert is desperate to show his worth!

Seeing that Robert was so self-volunteering, Thomas and Paul looked at each other. They all noticed the look of happiness in each other's eyes. Although the real yàn in the dog proves that the two drugs are safe and reliable, as long as the thought of that long thin needle is inserted into his lumbar spine, anyone will probably be a little frightened, right?

"Alright, then Robert will come first!"

After a moment's hesitation, John finally nodded.

To be honest, he really didn't want to test two drugs on these three people if he could. Regardless of the results of animal realization, after all, this was produced under the conditions of the 19th century, and John of purity or something really did not dare to guarantee 100% that there would be no adverse reactions, and this operation itself was a little dangerous.

Procaine has a very small possibility of allergic reactions, John had heard in his previous life that it was used to guide the death of patients during circumcision, and although lidocaine is relatively safe, he is not completely sure if he wants to do neuraxial anesthesia! You must know that after the anesthetic drug enters the body, there may be a certain danger, in addition to the blocking effect, it is likely to cause the arrest of breathing and heartbeat. And neuraxial anesthesia requires lumbar puncture, but lumbar puncture is generally the work of anesthesiologists and neurosurgeons, and John really doesn't remember doing it himself.

But apart from the three people in front of him, John really didn't have any other candidates.

Maybe it would be possible to find a homeless man and give him a lot of money, but John was reluctant to make such a choice, and the professional doctors were more accurate in describing the feeling and effect of anesthesia!

So no matter how much risk there is, John can only choose to do it.

Nowadays, the gas inhalation anesthesia used in surgery is more dangerous, especially for things like chloroform, which can kill more than 1 in 10 patients on the operating table every year, at least John's choice is still relatively less dangerous. It is impossible to reduce the risk to such a low level as the future generations, John can only think about the possibilities in advance and be well prepared to reduce the risk to the lowest possible level.

After a few thoughts in his mind, John took a deep breath and said, "Everyone, let's start preparing!" ”

As soon as John's order was given, Paul and Thomas were busy. Lumbar puncture does not require too complicated conditions, simply put, it requires a specially designed long needle, but in order to ensure the absolute safety of today's real yàn, we must strictly implement aseptic measures.

Taking out his already sterilized rubber gloves, hat, and mask, John began to arm himself fully.

Thomas had already taken out a long glass box, and several slender puncture needles in it flickered frequently in the light, which made Robert, who was always paying attention to their movements, feel a chill in his heart, and his tongue suddenly became a little dry.

It's too long!

According to the previous explanation and the animal he had seen, John was going to insert the slender puncture needle from Robert's lower back into his spine, and then inject anesthetic into it......

After a little thought, Robert couldn't help but shiver!

"Robert, lie down on your side."

Not noticing the change in Robert's mood, John said in a deep voice after seeing that he was ready.

John's voice was a little muffled through the mask, but it still clearly reached Robert's ears, and his heart instantly beat wildly a few times before taking a deep breath and nodding; "Good!"

Robert lay on his side on the bed, lifted his clothes, and left his back to John.

Motioning to Thomas, who was beside him, to bring over the iodine tincture, alcohol and cotton balls that had been prepared long ago, John sat behind Robert with his hands raised, took a deep breath and said in a deep voice: "Robert, are you ready?" ”

"Ready."

Forcibly suppressing the violent heartbeat, Robert quickly closed his eyes and responded angrily.

John didn't hesitate at this time, leaned forward a little and said in a deep voice: "Robert, I'm going to detoxify your piercing site first, it may be a little cold" (to be continued............
