Harm of voluntary blood donation (an old doctor with conscience reveals the inside story of blood donation)
Permission ┊ Delete
Recently, the fallacy that blood donation is harmless to health has been overwhelming. As an ordinary medical worker, I feel obligated to make a reasonable explanation.
First of all, what is blood? Blood contains three kinds of blood cells: red blood cells, white blood cells and platelets. Every component of blood has its special function:
Plasma can bring water, salt, nutrients, hormones and drugs into our tissues, and bring 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 the blood vessel to prevent further blood loss. Red blood cells are the most abundant cells in the blood. They are full of red hemoglobin, so the blood looks red.
As we all know, survival is inseparable from oxygen. Oxygen inhaled into the lungs combines with hemoglobin and is transported to various tissues of the whole body to complete cell metabolism. The life span of red blood cells is only 120 days, and they are destroyed in 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 donating blood will weaken or even lose the above blood function.
To put it simply: the decrease of red blood cells will make all organs of the body not get enough oxygen, and the life function of cells cannot be exerted. Dizziness after blood donation is because the brain can't get enough oxygen supply, which is the same as 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. The reduction of immune ability will give an opportunity to viruses that were originally insignificant, such as colds. By the way, another name for 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 unfortunately injured after donating blood. By the way, one of the most serious consequences of leukemia is thrombocytopenia ("blood suspicion" should only be seen by the elderly? Someone said, Ben, what you said is wrong. Everyone says that after donating blood, the body will produce enough blood to supplement it. Just now I said, "All blood cells are differentiated from hematopoietic stem cells in bone marrow."
The life span of hematopoietic stem cells is very long, which means that the hematopoietic function of hematopoietic stem cells is not infinite. There is a simple example: the bone marrow hematopoietic function of most elderly people is only 50% of that of young people. Because of the decline of hematopoietic function, anemia is prone to occur and it is not easy to recover. So 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. Plasma consists of water (9 1%), protein (7%), lipids (1%), sugars (0. 1%), inorganic salts (0.9%) and metabolites. . . Look, its hook is broken? ]]] Give a simple example: after donating blood, you will feel thirsty. Because you need to replenish plasma, the blood station will provide sugar water or milk for free. That's why, understand? Others said: I know everything you said, but I will give it for the happiness of the majority of patients. All right! You're 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 may have worked in the hospital longer than you. I have to tell you that it is precisely because of the enthusiasm of unpaid blood donors that patients bear the higher cost of blood use. Because of the huge profits of blood, the government monopolized the blood collection channels. When there was no blood station, the price per 200mm of blood was 70 yuan RMB, and now the price per 200mm of blood is about 200 yuan RMB.
Moreover, in the past, it was necessary to pay corresponding economic compensation to blood donors. Now they donate blood for free and don't need to pay any financial compensation to the blood donors. Our hospital goes to the blood station to buy blood, all of which are real money, and there is no shortage of a penny. These costs can only be passed on to patients, but there is nothing we can do. And because of a large number of unpaid blood donors, farmers and laid-off workers who used to live by selling blood have now broken their financial path and embarked on the road of crime!
Some people say: can't blood donors use blood for free? Yes, first pay the blood money in the hospital, then go to the hospital office to issue a certificate, then ask the doctor to sign it, take your ID card, medical record, operation notice and blood donation card, then stamp it at the health bureau, and then apply for a refund at the blood station. There are all handlers, and some places also stipulate that patients must handle it in person! I met many patients and finally gave up the blood refund fee of 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 physical examination? 2004.08.24 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 bank to the first blood for free? It's hard to say. Anyway, Chengdu dumped hundreds of thousands of CC, and some blood was sold to pharmaceutical factories as raw materials. Basically, when there is a problem, it is dumped in batches. This kind of thing is not exposed in every city. People in blood stations are basically retired soldiers or social idlers. There are few medical college graduates, and the benefits are surprisingly good. There are tens of thousands of blood collection vehicles at the end of the year, believe it or not.
Finally, have you really seen doctors who often donate blood for free? The annual salary of ordinary employees in blood stations is 250,000, which sounds a bit suspenseful and can't help but make people doubt its authenticity. However, if so, what will people think? Judging from the situation reflected by netizens' posts, the reason why blood station employees can get high salaries is because the blood station has a public resource of unpaid blood, and they use monopoly public resources to do unprofitable business. Citizens donate blood for free, and blood stations charge hospitals for blood supply. Although there must be a cost in the process of blood collection, it is not as high as the price of blood stations sold to hospitals, which brings rich income to blood stations. It is understood that the standard blood price of blood used in Guangzhou hospitals now is: every 200ml 220 yuan of whole blood, 50 or 100 ml small-dose whole blood charges 20 yuan per bag; Other rare blood group whole blood, 200 ml 660 yuan. God only knows how much money the blood station can make from it. Some netizens posted posts to expose the tricks during the period. A netizen said, "I heard from Xiao Yan (a staff member of a blood station in Hunan) that the blood station will draw 250 milliliters privately and deduct 50 milliliters for underground transactions. Only this one, the blood station can get each person 1 10,000 yuan every year. "
According to medical evidence and actual situation, no matter whether your constitution is strong or weak, blood donation will cause damage to your body, and it is almost irreparable damage, which may appear immediately or many years later.
Xuanchuan's statement that there is no harm to the body is purely one-sided by Western medicine. Even if doctors do, how many doctors will donate blood? The answer is very few, because they know that blood donation is harmful to health.
In fact, everyone can know the truth with a little attention, but the media will not report it publicly, because if everyone knows, who will donate blood?
The immorality of local hospitals and news media lies in the obvious harm of blood donation to the body, and in order to dispel the concerns of blood donors, the hospital even said that blood donation is also beneficial to the body. I think this is a shame for doctors and journalists. We should clarify the truth publicly and let people donate blood clearly and willingly.
ps:
1. Blood vessel damage caused by blood donation cannot be repaired for life. Vascular trauma caused by blood donation may lead to vascular rupture under the pressure of unknown external force.
2. Blood donation is addictive. Regular blood donation will strengthen the hematopoietic function in the body and lead to the feeling of vasodilation. Only regular blood drawing can alleviate this discomfort.
3. After blood donation, the blood volume in the body decreases, resulting in insufficient oxygen supply to the brain. At this time, the body will produce an acidic component to increase the oxygen content in the blood, and this acidic component has a huge adverse effect on the brain cells of the human body, so people who donate blood will feel dizzy. Long-term blood donors will cause slow response and reduced mental agility. Therefore, it is best for workers who need brain power not to donate blood.
4. The total amount of human blood is about 4000-5000cc, of which about 20% of blood is stored in organs, which can be quickly replenished when the human body is accidentally injured. However, human organs will age. In the case of aging and physical weakness, when accidentally injured, the body will no longer produce blood as quickly as it did when it was young. At this point, you will increase the death rate because of excessive bleeding and insufficient blood supply.
Increase the chances of being infected too much, such as AIDS, hepatitis B and other highly pathogenic infectious diseases. Despite the safety protection, it is inevitable. The probability of infection always exists.
6. Others: It has not been scientifically proved, but many blood donors on the Internet say that regular blood donation can promote weight. In other words, regular blood donation can easily lead to obesity. In this regard, there are many comments from blood donors on the Internet. Some blood donors say their weight gain is slow, while others say their weight gain is linear.
