Regardless of the era, war seems to be one of the important driving forces for the development of science and technology.

And it is very ironic that medicine is obviously a discipline that saves lives, but its rapid development has also been greatly promoted by the war, and the larger the scale of the war, the faster it will develop.

The most typical example, of course, is penicillin, which changed the history of medicine.

If it weren't for the massive Second World War, God knows when people would have paid attention to penicillin as a drug and invested heavily in researching it to make it possible to produce it industrially.

Twenty years earlier, in the First World War, advances in surgery were progressing at a speed beyond human imagination, such as the principles of surgical trauma, which John had just proposed, and the blood transfusion technology......

In the eyes of ordinary people in later generations, blood transfusion does not seem to be so complicated.

The blood collection vehicle collects people's blood, sends it to the blood bank, and then supplies it to the hospital, and when there is a need for a patient, it can be matched and then injected into the patient's body. In fact, this is not a high-tech technology more than 100 years later, and all that is required is a high sense of responsibility, patience and meticulous work.

But at the end of the 19th century, blood transfusion was the real "frontier of medicine"!

Even physicians who specialize in this do not know how much blood to draw so that it does not affect people, do not know whether the blood donor should be checked for infectious diseases before blood is drawn, do not know what kind of effect blood transfusion may have on patients, and of course, do not know that blood should be compared with the patient's blood type before blood transfusion...... By the way, because John? With the appearance of Mr. Huntelaar, many people already knew about it, and some people began to match their blood types according to his method.

So the last two years. There have been more reports of successful blood transfusions.

However, in the eyes of John, there are still many problems with these blood transfusion studies led by physicians, and there are many risk factors, and it can even be said that their success is often due to luck. For example, it's important to note that no one among the physicians has yet used indirect blood transfusions. Often, a tube is used to connect the blood vessels of the donor and the patient......

So even if John wants to perfect the technology, there's a lot of work to be done.

However, as one of the important foundations to promote the development of surgery, blood transfusion technology has a very important position, so John has already had the mind to work hard in this area. As soon as Kelly mentioned this, he naturally agreed.

While Professor Bergmann was preparing some of the things he needed, Johann plunged headlong into the physiology laboratory of the University of Berlin Medical School, which he had a good relationship with and which he was able to borrow, which he continued until the end of August and the beginning of September......

……

When I came to Charlotte Hospital again. John was much more relaxed.

The work in the lab is going very well, Ehrlich has just finished the paper to himself, and Professor Bergman has also prepared it, so everything seems to be going so well. Relaxation is always a pleasure, and it also gives John more of a closer look at the surgical building after a year's absence. The first two times he came, because he had something in his heart, and there were too many people who came forward to greet him in surprise, he couldn't take a closer look at the place where he had worked.

It was clear that everything in Charlotte Hospital surgery was on the path he had hoped for.

Although the hygiene standards in the building are not as good as those of Heinz General Hospital in New York. But overall it's pretty good, at least there's no obvious dirt to be seen. The physician's attire is a uniform white lab coat. The nurses are the same, and they are all neat and clean, and when they pass by the ward, they all look neat and orderly. The only thing that makes John a little regretful is that after all, it is an old building that was built a long time ago. The corridor is still too narrow, even the lighting of the rooms on both sides is very poor, and the overall look is still relatively dark. In addition, the ventilation is not satisfactory, and it is summer, so there is always a damp and unpleasant smell between the noses.

After getting used to staying at Heinz General Hospital, he returned to Charlotte. No matter how you look at it, there are a lot of problems.

But......

"It's already pretty good."

As he approached the door of Professor Bergman's office, John shook his head lightly and subconsciously said something to himself. In any case, the Department of Surgery at Charlotte Hospital is the place that he looks up to the most besides Heinz General Hospital. Even the hospital where Liszt worked, which I had just seen not long ago, was far worse than here.

"Gotcha! Get! ”

As he thought, John knocked on the door of Bergman's office.

No response was heard, the door was opened from the inside, and Professor Bergman behind the door greeted him with a smile, "Good morning, John." ”

"Good morning, Professor."

With a slight surprise, John quickly took his thoughts back from the chores.

Looking behind Professor Bergman, two doctors in white coats were sitting on the couch, and when they saw John come in, they quickly stood up—all very familiar faces!

"Gentlemen, I don't think I need to introduce him, do I?"

Turning his head, Bergman said to the two young surgeons with a smile on his face.

To say that he is a young physician is actually only relative to Professor Bergman himself, both of whom look to be about thirty years old, and are in the golden years of a surgeon. Compared with later generations, the total amount of surgical knowledge in this era is really limited, but the accumulation of experience is still a necessary process, so the age of thirty is the stage when the combination of the two aspects is relatively perfect, and it is relatively easy to accept new ideas and new knowledge.

These two surgeons were the assistants Bergman had found for John.

Looking at the tall young man in front of him, the two surgeons immediately smiled, and one of them waved his hand again and again: "Professor, Mr. Huntelaar is the former deputy director of surgery, how can we not know each other?" Good morning, John. ”

"Good morning, August, good morning, Ben!"

He stepped forward and hugged the two surgeons, and John greeted him warmly.

As the leading Charlotte hospital in Germany and even in Europe, the scale of surgery is still quite large, especially in the past two years, because of the progress of disinfection, local anesthesia and appendectomy and other technologies, the success rate of surgery has increased significantly, or the incidence of postoperative infection has decreased significantly, attracting more and more patients to come, and the hospital has naturally increased its manpower, and now the number of doctors alone is about to exceed 20 people, if you add many students and doctors who come to study, more than 60 people can work!

August? Fisher and Ben? Lesit, is one of them.

Before leaving Berlin, John was quite familiar with the two of them, and at this time he was naturally very satisfied with the selection of Professor Bergman, and said with a smile: "August, Ben, we are going to work together again, although the time will be shorter, but at least two or three months, I hope we can work together happily!" ”

"Haha, it's been a long time coming."

The two surgeons smiled at each other and replied in unison.

For and John? Almost every surgeon at Charlotte Hospital could not have refused, because over the past few years, they had seen very well how good this young man was, and how much they could benefit from working with him. Going forward, Thomas has become a new surgeon, Paul is now one of the authorities on anesthesia, and the biggest beneficiary is undoubtedly Professor Bergman and the Department of Surgery at Charlotte Hospital, now even more famous!

Follow Mr. Huntelaar, that must be right.

Of course, John himself knew this very well, so he didn't have too much politeness with the two of them, and nodded very simply: "That's good, you guys first find two clever nurses, and let's start animal experiments from tomorrow......"

……

Sorry, it took two days.

I couldn't write it the day before yesterday, and it hurt my hand yesterday, and my right thumb and middle finger hurt terribly, and it took me hours to knock this chapter today, and let's see if I can relieve it tomorrow. (To be continued......)
