Europe, Berlin.

“…… In the long run, I think it is a must to establish a blood bank in every city. ”

In the physiology laboratory of the University of Berlin, facing Howard? Kelly and Werner? Sprint, John said confidently: "Now maybe most people don't see the importance of this, but just think about it, with the maturity of blood transfusion technology, and of course, the progress of surgical level, the future obstetrics, gynecology, surgery will have higher and higher requirements for blood transfusion, and it is unrealistic to temporarily find people with the same blood type to provide blood......

"However, the storage of blood is a big problem!"

After listening to John's words, Mr. Sprint couldn't help but frown.

"So, it depends on the progress of technology!"

Smiling slightly, John waved his hand and said, "Who knew from the doctors a few years ago that blood transfusions should consider blood type? It wasn't until I came up with the blood group theory that many people started to work on it. Therefore, I believe that as long as blood transfusion proves to be safe and reliable, many people will naturally study it, including the storage of blood, and I will definitely not use it for long! ”

While the two of them were contemplating their eyebrows, John suddenly asked, "Werner, you should have sorted out all the results of animal experiments, right?" ”

"Well, it's all sorted out."

Mr. Sprint, an associate professor of physiology, was in good spirits and hurriedly handed over the materials to John.

"We did a total of twenty experiments."

Howard next to him? Kelly took a deep breath and said in a deep voice, "Dogs, rabbits, and rats were used, judging by the results of the experiment...... It didn't achieve our ideal goal, mainly because the problem of blood clotting was a bit troublesome. ”

"Hmm......"

While quickly flipping through the results of the experiment in his hand, John couldn't help but frown.

Of course, he had long anticipated the problem of blood clotting, and in this era, doctors used syringes to draw blood from blood transfusions. Then it is injected into the blood vessels, or a tube is used to connect the donor and the blood transfusion, and the pressure difference caused by the height is used to transfuse the blood, which will naturally cause blood clotting trouble for a longer time. It's just that John, who had never done a similar experiment before, didn't expect that the impact of this problem on the experiment would be beyond expectations!

After reading the results of the experiment, John frowned and pondered.

Look at John's frowning face. Howard? Kelly couldn't help but speak, "John, perhaps...... Can we consider adding saline to the blood? ”

"Salt water?"

After hearing Kelly's words, Mr. Sprint was stunned.

"Yes, Salt Water!"

Nodding, Kelly patiently explained: "In fact, I remember that ten years ago, many doctors in the United States gave milk to patients, that is, to infuse milk or goat's milk into patients who had lost a lot of blood, but because more and more patients died, some people later began to infuse patients with saline, and the effect was better...... Maybe. We should give it a try. ”

"Uh......"

After listening to Kelly's suggestion, John suddenly had a black line in his head.

After all these years of being reborn, and several years since he re-entered the medical profession, John always thought that he had become accustomed to the whims of this era...... No, I should say that I am brain-dead, but when I heard Kelly talk about the strange thing of transfusing milk into the patient's veins, he still couldn't describe the feeling in words......

However, if you infuse saline, it does make sense.

Fundamentally. The role of blood transfusion is actually in many aspects, such as replenishing blood volume. Improve circulation, increase oxygen-carrying capacity, increase plasma protein, improve body immunity and coagulation function, etc. If saline is given to a patient who has lost too much blood, it is actually to replenish blood volume, and in many cases it is indeed effective.

It's just used in blood transfusion research. It doesn't make much sense.

Shaking his head, John put these messy thoughts aside, and waved his hand after a slight groan: "That's it, I'll think about the problem of blood clotting and solve it as soon as possible......"

Speaking of which. John was absolutely confident.

This is certainly not because of his hubris, but because he knows very well that the use of sodium citrate in more than 20 years will solve the problem of blood clotting after leaving the body, and will make the standard that blood transfusions and donors must operate at the same time and in the same place become history, and at the same time promote the birth of blood banks. John, who is familiar with this period of history, certainly understands that just as indirect blood transfusions will replace direct blood transfusions for most of the future, blood banks will also replace temporary blood collection in the operating room, and the blood drawn from the human body will no longer coagulate quickly.

But well......

"It's too early to think about that."

Blinking, John said with a smile: "At present, we still do a good job of experiments, and I look forward to our research results being used in clinical practice as soon as possible......."

……

Looking at John, who was sitting peacefully in front of him, Professor Bergman's eyes looked very strange.

John's heart was also very strange, because as soon as he arrived at the hospital this morning, he was called to Bergman's office before he could say hello to his two surgeons, and the professor of surgery had been looking at him with a strange look since then, and he did not say why he had been called.

After a moment of silence, John, who had something on his mind, couldn't help but ask; "Professor, did you call me for something?"

"Hmm."

Nodding slowly, Professor Bergman finally spoke, "John, you seem to have been busy lately. ”

"Yes, there's been a lot going on lately."

Slightly stunned, John nodded a little puzzled.

Of course, he was very busy during this time, in addition to many things on the side of the pharmaceutical company, the two little doctors and nurses in the surgery needed training, Kelly and Sprint needed guidance, and even the preparation and purification of antitoxin serum required him to go to the laboratory often to do it himself, can he not be busy?

But what does it have to do with Professor Bergman?

The doubts in John's heart naturally fell into Professor Bergman's eyes, and she couldn't help frowning and said, "John, you won't forget that there is a medical conference at the end of this month, right?" It was the largest medical conference in Germany every year, and you had to take it seriously if they sent you a formal invitation and gave you an academic lecture! ”

"Uh......"

After listening to Professor Bergman's words, John couldn't help but roll his eyes.

Of course, he would never forget the medical conference at the end of October, but as soon as he heard Professor Bergman say that it was the largest, John couldn't help but twitch the corners of his mouth. In later generations, the hospital where he worked held a training course and had 180 people, and the conference attended by one or two hundred people in the first year could become the largest in Germany, and the sharp contrast really made him a little speechless.

Of course, there's really nothing to compare to.

In those days, telephone calls were still a luxury, telegraph fees were calculated by the number of words, and a journey of several hundred kilometers was considered a long journey, and the scale of a meeting of one or two hundred people was indeed quite remarkable. In this regard, I am afraid that only those doctors with high status and income are eligible to participate, so the standard of the conference is very high.

Thinking of this, John took a deep breath and smiled slightly: "Don't worry, Professor, I've been so busy for this academic conference recently, and I won't let you down when the time comes......" (To be continued......)
