After coming out of the Brister house, John was a little upset.

It is true that Miss Anna, who has always wanted to see each other again, is very beautiful, but in the company of the Bristers, John has no chance to be alone with each other, and he can't even say a few words, how can he not be depressed?

Returning home with regret, John picked up his pen again and began to write and draw on the blank paper, and it was about time to "hand over" with Bergman, and the whole report must be written anyway, and as for the number jù or something, it can only be pieced together according to the memories in his mind, and it is impossible for 19th-century surgeons to see the flaws......

……

Time flies, and it's another week.

It was a Tuesday afternoon when John came to the surgical building at Charlotte Hospital again, and he brought Bergman a thick stack of papers, twenty or thirty pages, and placed them on his desk: "Professor, this is a detailed plan that I have put together, please take a look!" ”

"Good!"

Professor Bergman, who was looking forward to it, raised his eyebrows, took it and immediately looked at it.

Since hearing what John said last Tuesday, Professor Bergman has been very interested in what he is saying, and has set aside half a day this afternoon, so he will carefully turn through the pages at this time. Across from him, John sat in a chair drinking coffee brought in by a nurse, calmly awaiting Professor Bergman's inquiry.

John has full confidence in this plan.

To be precise, John was confident in what he would learn a hundred years later, and the report had many suggestions for preventing infection, in addition to several ways to replace carbonic acid. Bergman, who is not afraid of knowledge, does not know the goods......

You only have to look at the expression on Bergman's face at this time.

From the calmness and calmness when he first looked at it, to the solemnity after reading the general narrative, and then to the surprise when he was implementing the specific plan later, Bergman's expression changed as quickly as an actor. Especially when he was about a quarter of the way through, John finally saw the surprise he had been waiting for!

Putting down the plan in his hand, Bergman took a deep breath, looked at John and asked, "John, this high-pressure steam sterilization mentioned in the article...... Have you really tried it already? ”

"Yes, it's been tried."

John nodded hurriedly. Said solemnly: "Professor, for this reason, I also specially bought a microscope to confirm my idea, now whether it is steam disinfection or boiling sterilization, it can effectively kill bacteria, I am sure of this!" ”

There are many things written in John's proposal, but the central point is the perfection of surgical sterilization technology!

The autoclave sterilization method was boldly proposed by John.

This was the most important medical moment in Bergman's life. John returned to the real master without any distress, and of course he had to be at the front of everything. And in addition to the steam sterilization method, John also proposed the boiling method, that is, the method of boiling in water for a long time to sterilize, which can be used to disinfect items such as rubber materials. With these two methods, it is basically possible to deal with most of the surgical instruments and dressings used in this era, as for dry heat, ionization, liquid medicine, etc

Hearing that John had verified it for himself, Bergman was completely moved.

The sterilization and disinfection effect of stone carbonic acid is actually quite good, but it is more irritating. It's a bit damaging to the skin, and secondly, the smell of this thing is too pungent, which has attracted too much criticism from too many people. Bergman had long wanted to find a new way.

"Well, you can give it a try."

After a moment of silence, Bergman nodded, although he didn't say much, but in his heart he had already decided to test it as much as he could. Both steam and boil sterilization are very simple to operate, and the verification effect is extremely easy, and it does not take long to determine.

After a brief pause. Bergman then asked, "John, what you wrote above about using alcohol instead of carbolic acid to disinfect the hands of the doctors. It's also verified, isn't it? ”

"Yes, sir."

John smiled. He replied respectfully: "However, after many times of repetition and practice, not all high-concentration alcohol can have a disinfection effect, only about 7o%-75% alcohol does!" ”

The principle of alcohol sterilization is to cause protein coagulation in the bacteria, but the concentration of alcohol is too low to do, and if the concentration is too high, it will even form a protective film on the surface of the bacteria, but it protects the bacteria, and only 7o%-75% is medical-grade alcohol. But John couldn't have said these things......

"Hoo ......"

Perhaps to hide the excitement in his heart, Bergman exhaled heavily.

If, as John says, two alternatives to carbolic acid can be found at once to solve the problem of surgical instruments and the disinfection of physicians' hands, then these two points alone will be worth enough for this project!

Seeing that Bergman began to ponder with a happy brow, John was a little anxious, and hurriedly smiled: "Professor, you haven't read more than half of this plan......

"Oh? Okay, haha, I'm sorry! ”

Bergman was stunned for a moment, then smiled, nodded repeatedly, and then flipped through.

John's twenty or thirty pages of report would be an exaggeration if only two ways of disinfection were proposed, and it would not be worth John's time for it. Having had the privilege of being a pupil of Bergman, and that teacher was one of the most important figures in the history of surgical sterilization, John simply picked out all the things that could be implemented in this era—most of them that could be explained purely theoretically, without much scruples.

To his surprise, however, as Bergman looked back more and more, the professor of surgery's brow gradually furrowed, as if he didn't quite approve of what he saw!

"What's wrong?"

John was a little worried, because Bergman was not as surprised as the previous one when he looked at the content in the back, and he was getting faster and faster, and it took him about the same time as the previous one to read such a thick stack!

"Professor. What do you think? ”

Seeing that Bergman had finished reading the rest so quickly, John's heart jumped, and he suddenly had a very bad premonition.

"Gotta ......"

Fingers tapped lightly on the plan, Bergman frowned and pondered for a moment before suddenly frowning and asked; "John. Improving the disinfection of surgical instruments and hands now is valuable and definitely worth a try, but something else written later...... Is it really necessary? ”

"Huh?"

Hearing this, John was stunned.

Now that John seemed very surprised, Bergman frowned and continued, "John, those things you mentioned later. For example, does it really make sense for doctors to disinfect their surgical clothes, to disinfect operating rooms after each use, and even to disinfect wards frequently? ”

"This ......"

After hearing this, John was completely speechless.

This is a plan that took a lot of John's thoughts. There are a lot of things in the later generations of surgical textbooks, of course, more of his experience as a surgeon, such as in addition to the disinfection of surgical instruments and hands, the cleaning of the overall environment of the hospital, the environmental disinfection of the operating room, the hygiene measures of doctors and nurses, etc., John has a very detailed description, it can be said that with this information, the level of surgical disinfection can instantly burst into decades!

But......

John never thought of it. Bergman would have asked if it was necessary, if it made sense!

Boss, you're Bergman!

"Professor......

He opened his mouth. John wanted to say something, but it occurred to him that if the other party didn't accept his point of view, what was the point of saying more?

Bergman saw John's disappointment, and felt a little helpless in his heart, shook his head and said; "John, though, judging by the reasons you put forward. These measures may do a good job, but are they really the ones that have to be done? How effective are these measures in preventing infection? And. Do you know how much it would cost us if we really realized all your builds? ”

The limitations of the times. In Bergman's body, he is drenched in the fullest.

Even though he was a master of steam sterilization, John's overly radical changes later in the report still made him resist. After all, many things are not directly related to surgery, and if all the improvements proposed by John are really implemented, a large number of disinfection items will have to be purchased every month, many sets of surgical gowns will have to be purchased for each doctor and nurse, and even patients will have to wear hospital gowns when they are hospitalized, and they will be disinfected after each use......

In this way, the cost of surgery at Charlotte Hospital will at least double in an instant!

Even as a professor of surgery and head of surgery at Charlotte Hospital, Bergman did not have the ability and authority to achieve this number. Especially when most of the people who come to the hospital to see a doctor are poor, it is difficult to support the fees charged!

So even if he was a little moved after reading the report, Bergman subconsciously chose to refuse.

As a surgeon, of course, he is willing to try the measures that John said, if nothing else, the hospital is cleaner, and the doctors and nurses are neater and more comfortable to look at, isn't it? But as the head of surgery, Bergman had to think about everything, especially the economic factors!

So seeing John's face full of disappointment at this time, Bergman could only smile and comfort him: "John, it's good that you have ideas, but I think we should focus on the operating room!" I will try my best to test these three disinfection methods...... Hmm, I will also adopt your proposal for frequent disinfection of the operating room, and you will be responsible for this matter, how about it? ”

As he spoke, Bergman gave John a sweet date to eat.

This wasn't meant to give John a job, and it was extremely rare for a student who had just entered surgery to gain such trust.

“…… Okay, Professor. ”

After a moment's silence, John nodded and agreed, and the expression on his face had already returned to his former calm, and no one could see what was going on in his heart...... (To be continued)
