As a sign of respect, John invited Bergmann, Liszt, and Bierrot to speak on stage. These three are all big figures in the field of surgery, and it doesn't take much time for each of them to speak for two or three minutes on stage, and they can also make them show their faces and improve their favorability, this kind of thing is naturally impossible for John to let go.

As for Koch's words, he has been in power for a long time.

This was something that John had communicated with Koch before, so the bacteriological guru stood on the stage for half an hour and shared his views on the importance of surgical disinfection and new disinfection techniques. Koch had been focusing on wound infections for a while before he came to Berlin, so he had these things at his fingertips. Although most of the surgeons, especially those who are willing to come to Berlin, have embraced the idea of surgical sterilization, Koch's speech did not really have much substance, but ......

That's Robert Koch, after all!

In the whole of Germany, it is widely believed that Koch will be the successor of Fürchaux's status, although the old man is still active in the academic arena, but Koch's prestige in Europe in recent years can be said to have reached a peak, with him attending this conference and speaking on stage, everyone suddenly felt that this small auditorium suddenly became tall!

Of course, John's purpose was achieved.

Making good use of the resources at hand, a skill that John had learned in his previous life, especially when his prestige had not yet reached a certain level, and the presence of the likes of Koch and Liszt could add a heavy touch to the meeting. On this point, just look at the expression on the face of Hines, editor of the German Medical journal in the audience......

"Whoa......

When Koch finished his speech and bowed slightly to the audience, the auditorium burst into thunderous applause!

As the bull stepped down, John took a deep breath. Walked up quickly. When he stood still on the stage, the applause also stopped, and John laughed loudly: "Thank you, Professor Koch, for your wonderful speech, and on behalf of the Department of Surgery at Charlotte Hospital, please allow me to thank you again!" ”

With that, John bowed in Koch's direction.

Koch nodded in return with a smile on his face, and he was in a rather happy mood. In fact, he was originally a physician as well. Later, he gradually focused on the study of bacteriology. And for John, a young surgeon, Koch is also quite fond of him, because in several exchanges before and after, John has expressed an in-depth understanding of bacteriology, which is quite a great thing in Koch's opinion, and Koch naturally doesn't care about it when he talks for a long time.

"Gentlemen."

After straightening up, John paused for a moment before he continued: "Today and tomorrow, we will be in this small auditorium, and the content is the three parts published in the journal German Medicine and The Lancet: surgical sterilization specifications, local anesthetic techniques, and appendectomy!" And the next four days. We will invite you to visit the Surgery Building to learn more about our efforts in these three areas, from the operating theatre, the ward, and the sterilization room......"

……

“…… Professor Bergman, you have a very good subordinate! ”

John on the stage was talking, and Professor Bierrot in the audience leaned slightly to the side and whispered to Professor Bergman next to him.

"Hmm, thank you."

With all eyes on John, Bergman nodded absentmindedly.

Anyone who suddenly walks into this auditorium. I'm afraid I will be taken aback by the age of the speaker on stage. In fact, with the arrival of surgeons these days, almost every physician who saw the real face of Mr. John Huntelaar was taken aback.

It's too young!

But the same. Anyone who sees John's appearance on the stage at this time will probably immediately forget his age, and will also ignore his immature face, and focus on the content of the speech!

Not humble or arrogant, not arrogant or impatient, calm and calm.

That's what almost everyone says about John at this time. John on the stage was not at all like standing on the rostrum of a conference for the first time, facing dozens of new surgeons in his peers, but like an old professor who had been in a high position for decades, and even compared with Koch just now.

Koch himself agrees, after vaguely overhearing Bergman and Bierrot's conversation. He looked at John on the stage, and shook his head secretly in his heart: "Such an excellent young man, he wants to do some kind of surgery, if he can study with me for a few years, his future achievements will be limitless......

……

For the surgeons, including Liszt and Bierrot, both John this morning and Thomas and the others in the following day and a half were undoubtedly extremely attractive.

The content of those papers in the magazine is still too simple after all.

In fact, a few papers can't summarize everything about local anesthesia, sterilization, and appendectomy, but only point out the core things. However, for surgeons who are very practical in their work, it is only possible to learn useful things by listening with their own ears, seeing with their own eyes, and even participating in it themselves.

As a result, John's speech was a huge hit.

In terms of surgical disinfection, John did not dare to mention Pasteur because of Koch's presence, but he started with Liszt's disinfection method 20 years ago, and talked about Koch's mention of high-temperature disinfection, and then to his own discovery of alcohol, high-pressure steam sterilization, iodine tincture and other methods, and finally went deep into the steps and specifications of disinfection and the control of the environment.

In terms of local anesthesia, John started with the anatomy of the spine, then extended to Freud and two American surgeons who tried anesthesia with kekayin, and finally talked about his own discovery of lumbar puncture, the invention of two local anesthetics and neuraxial anesthesia techniques.

In terms of appendectomy, in addition to collecting hundreds of cases and examining patients, John also pulled out Bilrot, who was present, and talked about his thoughts and ideas for creating this kind of surgery, from his first study of anatomy, pathological structure, to animal reality and the process of human surgery......

In a word, it is reasonable!

John doesn't go into the details, but what he offers is his own research ideas, or how he derives these new discoveries based on the relevant knowledge that is already available in this era. In this way, under John's analysis and explanation one by one, these results were summarized by him as if they were peeled off the cocoon.

"I see!"

Listening to John's explanation, the doctors' hearts let out a secret exclamation from time to time!

What sounded complicated and cutting-edge had become so simple in John's mouth, as if he could have made it if he had thought of it earlier. 、

"It's done!"

Looking at the changes in the expressions on the faces of the many surgeons in the audience, John's mood became more and more relaxed, and the tone of his speech couldn't help but increase a little.

The limitations of the times are too powerful.

Even Liszt's research on surgical sterilization, Billrot's research on abdominal surgery, and Koch's research on bacteria were ultimately limited by the level of medicine in this era, and the research time was long and inefficient. In addition, the communication conditions are extremely poor, which makes it extremely difficult to communicate research results. And for John, who has systematic knowledge, even if he only uses the theories and knowledge that have appeared in this era, as long as he strings them together with the theories of later generations, it is enough to give birth to a conclusion that shocks people!

So today, at this time, John did not hesitate to disclose the process of his "research".

Truth be told, he didn't expect these surgeons to learn this way, or what they would achieve in the future. He just wants to be able to tell others how he "researched" and how he discovered so many research results.

For him, that's enough.

“…… So, gentlemen! ”

At the end of his speech, John said loudly with a very bright smile on his face: "I still have a lot of ideas about the work of our surgeons, and I would like to welcome interested physicians to ......work together" (to be continued......
