The situation after blood donation

Recently, the fallacy that blood donation is not harmful to health is overwhelming. As an ordinary medical worker, I think I have an obligation to give a reasonable explanation. First of all, what is blood? Blood contains three kinds of blood cells: red blood cells, white blood cells and platelets. Each composition of blood has its special function. Plasma can carry water, salts, nutrients, hormones and drugs to our tissues, and take away metabolic wastes to the lungs and kidneys, and excrete them through breathing and urine. Among them, white blood cells can help your body resist infection, and the function of platelets is mainly to stop bleeding. When you are injured, they will stick together and block the hole in blood vessels to prevent further blood loss.

Red blood cells are the most abundant cells in blood, and they As we all know, survival is inseparable from oxygen, and the oxygen inhaled by people in the lungs is combined with hemoglobin and transported to various tissues of the whole body to complete the metabolism of cells. The life span of red blood cells is only 12 days, and they are destroyed in the spleen. All blood cells are differentiated from hematopoietic stem cells in bone marrow. This can clearly see the importance of blood to the body, so why is blood donation harmful to the body? Because blood donation will weaken or even lose the above blood functions. To put it simply: the decrease of red blood cells will make all organs of the body not get enough oxygen, and the life functions of cells cannot be exerted. The dizziness after blood donation is because the brain does not get enough oxygen supply, which is the same as the phenomenon of carbon monoxide poisoning.

The decrease of white blood cells will reduce the body's ability to resist viruses and make it easy to get sick. This is the reason for weakness after blood donation, and the decrease of immune ability will make viruses such as colds, which are originally insignificant, have an opportunity. By the way, another name of the famous AIDS is "acquired immunodeficiency syndrome". The lack of platelets will make the wound difficult to heal and bleed. Of course, no one will be unlucky enough to get injured after donating blood. By the way, one of the most serious consequences of leukemia is thrombocytopenia ("Blood Suspicion" should be seen by older people, right? Someone said: Ben, what you said is wrong. Everyone said that after donating blood, the body will produce enough blood to supplement it. Just now I said that "all blood cells are differentiated from hematopoietic stem cells in bone marrow."

According to conscience, hematopoietic stem cells have a long life, that is to say, the hematopoietic function of hematopoietic stem cells is not unlimited. There is a simple example: most elderly people's bone marrow hematopoietic function is only 5% of that of young people. Because of the decline of hematopoietic function, anemia is prone to occur and it is not easy to recover. Therefore, I think hematopoietic stem cells are consumables and irreversible! Others said: The book says that the blood volume will be replenished 2 weeks after blood donation. Yes, you are right, but please note: what is the supplement? As far as I know, the body should replenish plasma within 2 weeks. Plasma and blood are two concepts. The components of plasma include: water (91%), protein (7%), lipids (1%), sugars (.1%), inorganic salts (.9%) and metabolites. . . See, its hook is broken? ]]] Here's a simple example: after donating blood, you will feel thirsty, because you need to replenish plasma, and the blood station will provide sugar water or milk for free, which is why, understand? Others said: I know everything you said, but for the happiness of the majority of patients, I will give it. OK！ You are great. I admire you. However, when you don't donate blood for free, don't patients have no blood to lose? Of course not. Ben's working time in the hospital may be older than your age. I have to tell you: It is precisely because of the enthusiasm of unpaid blood donors that patients bear the higher cost of blood use. The price of blood per 2mm is 7 yuan RMB, and the current price is about 2 yuan RMB per 2mm.

In the past, it was necessary to pay the corresponding financial compensation to the blood donors, but now they donate blood for free, and there is no need to pay any financial compensation to the blood donors. When our hospital goes to a blood station to buy blood, it's all real money, not even a penny less. These costs can only be passed on to patients, but there is nothing we can do. And because of the large number of unpaid blood donors, farmers and laid-off workers who used to live in poverty by selling blood have now broken a financial path and committed crimes! Someone said: Isn't blood donors allowed to use blood for free? Yes, first pay the money for blood use in the hospital, then go to the hospital office to issue a certificate, then find a doctor to sign it, take your ID card, medical record, operation notice and blood donation certificate, then stamp it in the health bureau, and then go to the blood station to apply for a refund. The prayer handlers are all there, and some places also stipulate that the patient must handle it in person! I met a lot of patients, and finally gave up the blood refund fee at the blood station, believing that I was unlucky. Others said: blood donation can at least be checked for free. My supervisor told you that the blood bank only does the most routine blood and hepatitis B tests. There is even a report that I didn't verify. Let's have a look. Donate blood without medical examination? 24.8.24 Dazhong Net-Dazhong Daily Why didn't you have a physical examination before donating blood? A few days ago, the author participated in a voluntary blood donation, and the staff of the blood bank began a busy blood drawing work without a substantive physical examination of the voluntary blood donors. In the face of many people's questions, the staff of the blood bank explained that since the implementation of the Blood Donation Law, there has been no physical examination, which is the case all over the country. Finally, what is the attitude of the blood station to the blood that comes first for free? It's hard to say. Anyway, hundreds of thousands of CC were dumped in Chengdu, and some blood was sold to pharmaceutical factories as raw materials. Basically, it was dumped in batches when there was a problem, and this kind of thing was not exposed in every city. People in blood stations are basically retired soldiers or social idlers. Medical school graduates are rare and the welfare is surprisingly good. At the end of the year, there are tens of thousands of blood collection vehicles, and believe it or not. Finally, have you really seen any doctors who often donate blood for free? The annual salary of ordinary employees in blood stations is 25,, which sounds a bit suspenseful and cannot but make people doubt its authenticity. However, if this is the case, what do people think? Judging from the situation reflected by netizens' posts, the reason why blood station employees can get high salaries is because blood stations have a piece of public resources of unpaid blood sources, and they use monopoly public resources to do unprofitable business. The public donates blood for free, and the blood station charges the hospital for blood supply. Although there is definitely a cost in the process of blood collection, it is not as high as the price that the blood station sells to the hospital, which brings rich income to the blood station. It is understood that the standard blood price of blood used in Guangzhou hospitals now is: for every 2ml 22 yuan of whole blood, 5 or 1ml of small-dose whole blood will be charged with 2 yuan for each bag; Other rare blood group whole blood, 2 ml 66 yuan. God only knows how much money the blood station can earn from it. Some netizens posted posts to expose the tricks during the period. A netizen said, "I heard Xiao Yan (a staff member of a blood station in Hunan) say that it is stipulated to draw 2 ml of blood, and the blood station will draw 25 ml privately and deduct 5 ml for underground transactions. In this case alone, the blood station can get 1 thousand yuan per person every year. "

Baidu netizens said it was even more interesting: "It was a good thing to donate blood for free, but it was ruined by those black-hearted hospitals. We donated blood for them at a high price, and I gave it twice, and every time I told them that I would donate 2CC, but when I saw my Rh-negative blood, I thought it would be a contribution to society anyway, but their attitude was really good. This may be the reason why blood stations have become profiteering industries. "The annual salary of ordinary employees in a blood station in a city in the Pearl River Delta is 25," may be an individual phenomenon, but it is not unfounded for the whole blood station industry to get high salaries. The existence of this phenomenon is a wanton abuse of social love and conscience, because the public is offering love to the society by donating blood for free. All people who donate blood for free regard it as fulfilling their social responsibilities, hoping to save others' lives with their own blood, and never expect anything in return. However, the blood station regards this unpaid blood source as a tool to collect money and a source of high salary and welfare. The existence of this phenomenon is also a blatant challenge to social fairness and justice. Because this practice of using the monopoly position of public resources to accumulate wealth has created new nouveau riche and further widened the social distribution gap. Blood station, are you a love ambassador or a vampire? It is definitely a big social scandal to regard the unpaid blood source as a tool to collect money. For the country and the nation, it is absolutely a shame. It is definitely a blow to the public's love action. Let this ugly phenomenon exist, then people's love is no different from being eaten by dogs. Friend, will you donate blood willingly in the future?
