"Blood transfusion?" The first person to react was Yuanxu. He had devoted himself to medicine for many years and had never heard of "blood transfusion". He immediately became concerned when he heard what Zhou Tiansheng said. "Senior Brother Yuanxu, since Senior Brother Li has lost too much blood, let's give him a blood transfusion." Zhou Tiansheng replied. "Huh? Which medical book mentions this method? Why have I never heard of it?" Yuanxu was extremely enthusiastic about medical skills. When he encountered this miraculous technique that he had never heard of, he naturally wanted to get to the bottom of it. "Uh well I read an ancient book called "Blood Injection" when I was a kid, but I don't know where I threw it." Of course, Zhou Tiansheng knew about blood transfusions in his life, and anyone who lost too much blood due to a major accident would He needed to give the patient a blood transfusion, but when Yuanxu asked which medical book, he couldn't say "Introduction to Modern Medicine", right? In a hurry, I casually compiled a copy of "Blood Notes". Regarding blood transfusion, there are almost no relevant records in the history of medicine in my country. This may be because this matter is too strange and completely contrary to traditional concepts. Therefore, in our country, ancient people at most used animal blood to treat diseases, or bled blood to treat diseases. Few people would think about blood transfusions. However, in the West, there was the so-called "bloodletting therapy" in the Middle Ages. It was different from China's "bloodletting therapy". Although their "bloodletting therapy" was absurd and unruly, it also made their research on blood a lot ahead. In the 16th century, a mad patient named "Mory" suffered from an illness and wandered naked in Paris. He was taken by a nobleman to Denis, the royal physician, for treatment. Dennis injected a small amount of calf blood into Morrie's body, hoping to use the "gentle calf" blood to cure Morrie's madness. Morrie received a total of two blood transfusions. The transfused calf blood triggered a violent immune response in his body, putting Morrie in a state of high fever and shock that was on the verge of death. Fortunately, he survived and temporarily recovered within a few months. Calm is restored and no longer crazy. This miraculous treatment immediately caused a great shock in Europe, and blood transfusion therapy became fashionable for a while. However, it was not until Landsteiner discovered human blood types, the Frenchman Carrel invented vascular anastomosis, and Dr. Luinsen discovered that 0.2% citric acid can prevent blood coagulation and is harmless to the human body, and then blood cross-matching Relatively safe blood transfusion treatment can only be carried out after the results have been completed and become standard operations. "Tiantian, how sure are you of being able to get Junior Nephew Li Xu out of danger?" Zhang Songxi didn't care about medical books or not, he only asked about the results. "About 50%." Zhou Tiansheng hesitated and replied. "Huh? Fifty percent, which is not low. It is much better than relying solely on God's will." Zhang Sanfeng said, "Shengsheng, how exactly should I do this blood transfusion? Let me tell you about it." "Master, I was young at the time and was reading a book. I don’t quite understand it, and I don’t remember it clearly, so I’ll explain this blood transfusion method in detail, Grand Master, all my uncles and brothers, if there are any fallacies in my words, it’s a matter of human life, please correct me,” Zhou Tiansheng said! . "Well, you go ahead." Zhang Sanfeng nodded. Yuanxu's eyes lit up over there and he stared at Zhou Tiansheng intently. "Then let me start from the beginning. That ancient book says that there are four different blood types in the human body, type A, type B, type A and type B, and type yuan." Zhou Tiansheng smoothly changed the names of type A, type B, type AB, and type O. Got a name. "Junior brother, what are the differences between these blood types, and how to identify them?" Yuanxu asked impatiently. "Yuanxu, don't interrupt, let him finish." Yu Daiyan reminded him coldly. "Senior brother is asking, but I was just reading for fun at the time and didn't pay much attention to it. I can't remember how to identify it specifically." Zhou Tiansheng said honestly, it is related to human life, so you can't talk nonsense, and continued: " The book once said that blood transfusions should be of the same blood type, and the problem will not be too big. If the matter is urgent, the owner of type A and B blood can receive any blood type, and the owner of type Y can receive any blood type, but the amount cannot be too much. As mentioned in the book, the author of his book has traveled all over China, collected blood from all ethnic groups, and determined its types. He concluded that type Yu is the most common, about 41%, type A is 28%, type B is 24%, and type A and B are the rarest. , only seven points." After a pause, he thought for a moment, and organized his words. Zhou Tiansheng continued: "If the blood types are matched perfectly, there will usually be no major adverse reactions except for a few accidents. , and then blood can be transfused, which is transported from the artery of the blood donor to the vein of the recipient. "Artery? Vein?" Taoist priest Yuanxu couldn't help it. What Zhou Tiansheng said was simply ridiculous. It was unheard of, and for a doctor, it was really irresistible. This time Yu Daiyan was really curious, so he just let it go. "So that my senior brother will know that this ancient book is very different from the fundamental principles of Chinese medicine. Its author conducted extremely detailed anatomical analysis and comparative experiments based on the human body, completely disregarding my Chinese theories of yin and yang, five elements, and qi and blood. It comes from another lineage, so it is often different from my Chinese medical skills.terms of. " Zhou Tiansheng said, "It is inconvenient to go into details at this time. Let's just talk about the arteries and veins. The book says that arteries are the blood vessels that carry blood away from the heart to the whole body. They originate from the ventricles and return to the capillaries. Veins are the blood vessels that return from the whole body to the heart. They originate from the capillaries and return to the atria. ” The quiet sound of pindrops could be heard in Zixiao Palace at this time. Everyone listened to Zhou Tiantian’s clear and clear voice. To put it bluntly, they all felt that their ears and eyes were opened, and they did not pay attention to the strange terms such as atria, ventricles, and capillaries. Only Yuanxu murmured: "The heart is the master of the internal organs, the master of gods, and the master of blood. It's obviously the same as what I learned. "Tian Sheng, tell me straight, how do you choose the right person to give blood to nephew Li Xu?" How to find these veins and arteries? Then how to transfuse blood? "Yu Daiyan said straightforwardly. "In reply to Master, I really don't know how to choose the blood donor, so I can only choose at will, so I just said that I am only 50% sure. As for veins and arteries, I only know one artery, which is the radial artery. Its location is roughly where the pulse is usually felt, but it is hidden deeper. There is a vein on the back of the hand that can be used for blood transfusion, and there is also one on the inside of the elbow of the arm. The nearby blood vessels are locked by means of techniques, making it difficult for them to flow. The veins appear naturally. Well, the veins are dark blue. "As a homeless person, Zhou Tiansheng was forced to take many kinds of injections, so he still remembers some. "Oh! By the way, regarding choosing a blood donor, you should take the blood of both the donor and the recipient and put it in dilute salt water. If the two are compatible, you can try a blood transfusion; if the two are a mess, mix the egg white and egg yolk together, or mix them together. Form into small pieces, this is the so-called hemolysis reaction and agglutination effect, you must not lose! " Zhou Tiansheng suddenly thought. "Huh? Isn't this a way to recognize relatives by shedding blood? Yuanxu said.
