A needle, a long tube, a magical speed control device.

Heinz Medical Devices' IV kits, except that they are not disposable and not so elaborate, are almost identical to the IV kits of the future. So John easily hung up the "drip" on the three critically ill patients, and then patiently adjusted the flow rate under the hot gaze of Koch and others.

Again, the power of knowledge beyond the times is too great.

For any ordinary person in the future, going to the hospital for infusion may be something that must be experienced. A nurse had a needle stuck in the back of his hand, and then a plastic bag full of liquids hung high above him – an infusion bottle in the early years – was commonplace. But for people at the end of the 19th century, this device was so advanced that Koch, Kitasato Shibazaburo and others immediately looked straight at it.

"Next, it's up to each of them to make it."

After all the treatments, John breathed a sigh of relief and smiled bitterly.

Rehydration therapy is not a panacea, the three patients with mild symptoms are fine, if there is a two-pronged combination of rehydration and sulfonamide, there is a great possibility of rescue, but the situation of these three is too serious, it is likely that there has been organ failure, whether they can survive can only depend on their respective physical fitness and immunity level.

"I'll leave the rest to Mr. Ehrlich and Mr. Kitasato Shibazaburo."

After thinking about it, John simply whispered to Koch: "Professor, I'm afraid it won't be of much use for us to stay here, why don't we go and study together how to control the spread of cholera as soon as possible?" ”

"Well, that's fine!"

Hesitated. Koch nodded quickly.

Although Koch was eager to stay in the hospital and wait for the final results, he also found that John seemed to be very resistant to this and deliberately wanted to leave the hospital as soon as possible. So after thinking about it, he decided to leave with John, after all, the treatment of cholera is important. But in contrast, it is more important to prevent people from contracting this malignant disease as much as possible.

"This hospital alone has accepted thirteen patients today."

As he walked out, Koch said thirteen, the most taboo number in the Western world, with a heavy expression: "If it is treated as before, at least half of the patients will eventually die...... Hope your rehydration therapy works! ”

"Don't worry, it will work."

Smiling and nodding, John said seriously. He is confident that rehydration of cholera patients will prove to be the most effective treatment in the future.

"Still. The most important thing now is to control the spread of cholera! ”

After a slight pause, John immediately changed the subject.

"Well, that's right!"

Without hesitation, Koch immediately nodded and said, "I have sent someone to purchase a large number of sulfonamides for the treatment of cholera patients!" But alas...... Sulfonamides are effective in some patients, but ...... in others"

For Europe and the world at the end of the 19th century, there was a lack of treatment for infectious diseases, if not for the vast majority of diseases. In fact. Aside from treating malaria with natural medicines such as cinchona, there is basically nothing that can be done. Other words. Once people are infected with diseases such as cholera and tuberculosis, they either rely on their own immunity to carry it, or they can only wait for death to come.

It wasn't until John "invented" sulfonamides that all this finally changed!

As the world's first drug that can fight bacteria head-on, sulfonamides do not kill bacteria, but they can inhibit them. So for some diseases. will play a very important role. The body's immune system is capable of removing these foreign dangers, but either the body's immunity is too poor, or the number of foreign bacteria is too large for the immune army to resist. But when the two sides can't hold on or the body's immunity is slightly inferior, the addition of sulfonamides is likely to change the balance of strength between the two sides. Finally let the patient carry it; But if the difference in strength between the two sides is too great, then the effect of sulfonamides is really limited......

So shaking his head, John said in a deep voice: "Professor, all kinds of treatments are just the last step of helplessness, and it is more important to prevent it!" Professor, you're an expert in bacteriological research, and you know this better than I do, right? ”

"Of course!"

Koch's gaze froze, and he immediately nodded.

"So I strongly advise you to make a proposal to the Hamburg City Council immediately!"

After taking a deep breath, John said in a deep voice: "It is up to the government to intervene to eradicate Vibrio cholerae in public environments as much as possible, and on the other hand, to educate citizens to reduce the possibility of infection as much as possible...... Professor, controlling the spread of cholera is not complicated, and the recommendations I have made should be effective very quickly. ”

In order to deal with the cholera epidemic in Hamburg, John came up with a series of solutions.

The first is to control the source of infection, that is, the patients who have been infected with cholera, strictly isolate them in special wards or other places, and disinfect everything they excrete in addition to giving corresponding treatment!

Otherwise, it is natural to cut off the route of transmission and do a good job of public health.

In fact, the method is the truth that any ordinary person will understand in the future: don't drink raw water, everything you drink must be boiled before you can drink it; Don't eat raw or cold food, eat it when it's cooked; Pay attention to public health, especially the key points such as garbage dumps and sewage in the city, which must be cleaned as soon as possible; Others include getting rid of flies as much as possible, unclogging the city's small waterways, disinfecting the water system, and so on......

Speaking of which, the cholera pandemic in Hamburg was caused by contaminated tap water.

Therefore, John's suggestions are very targeted, if the Hamburg city government can start implementing it as soon as possible, not to mention that the cholera can be completely eliminated soon, it will definitely reduce the number of infected people significantly, at least it is not like in history, more than 8,000 people died in Hamburg in just a few months!

However, under John's expectant gaze, Koch's expression suddenly became awkward.

After a short silence and an embarrassed expression, Koch's reaction made John slightly stunned, and then he suddenly felt something bad in his heart, and hurriedly asked, "Professor, what are you...... Any questions? ”

"Uh......"

With a wry smile, Koch sighed helplessly: "John, I personally support your theory, but ...... But it will not be easy to convince the Hamburg city government......"
