June 14, 2022

It is the 19th World Blood Donaliated

This year's activity slogan is

"Blood donation is a kind of unity,

Join us, save life! "

The most wonderful feeling in the world is,

The blood you donate,

It flows in another person's body,

You walked into TA's life,

But I don't know each other.

Since the implementation of the Blood Donation Law in 1998, the number of blood donors and blood collection in my country continued to increase for 20 consecutive years. In 1998, the number of blood donors nationwide was about 300,000, which was nearly 15 million in 2018. In 1998, the national blood mining was less than 5 million units, and by 2018, it reached 25 million units, an increase of more than 4 times.

But when it comes to blood donation, many people will resist the mind, which is caused by misunderstandings of blood donation. Today, I will bring you the eight misunderstandings of blood donation.

Misunderstanding 1: Can't eat before donating blood

[Truth Daibai] Blood donation must not be empty!

[Reason explanation] Usually go to the hospital for a medical examination, and it is often required to be empty when taking blood testing, so everyone mistakenly believes that blood donation should also be an empty stomach, but it is not. Because the blood glucose content in the body is relatively reduced during an empty stomach, the blood capacity decreases after blood donation, which is more likely to cause blood donors to have a mild or severe blood donation reaction. Eating can increase the glucose concentration and blood capacity in the blood, which can greatly reduce the occurrence of blood donation, especially the occurrence of severe blood donation.

[Reminder] If you forget to eat breakfast, the major blood donation cars (houses) are prepared for you to prepare biscuits and candy.

Misunderstanding 2: Do not drink water before and after blood donation

[Truth Daibai] Drink more water before and after blood donation!

[Reason explanation] You can drink some sugar water half an hour before donating blood, because sugar water is easier to enter the blood. In addition, drinking water can promote blood circulation, reduce blood viscosity, fill blood vessels, and have a safe and comfortable feeling for blood donors. , So that the blood collection process went smoothly. After donating blood, the blood capacity needs to be supplemented, and the fastest way to supplement the blood capacity is to replenish water. By replenishing water, the blood capacity can return to normal within 1-2 hours.

[Reminder] Do not drink thick salt water before donating blood. This will make the number of red blood cells in the blood relatively small, and the plasma becomes more. For patients who need blood transfusion due to anemia, the blood quality is discounted. For blood donors, it also increases gastrointestinal burden.

Misunderstanding 3: After donating blood, it will cause obesity

[The truth is white] The cause of obesity must be too much in intake!

[Reason explanation] Under normal circumstances, blood donation will not directly cause the human body to gain weight, because hematopoiesis is not fat -making, and it cannot simply equalize the two. After the blood donation, the human body will complete a cycle and supplement of all blood in the whole body within 120 days. During this period, if there is no special case, the human body will increase the demand for nutrition. Because of this, many people often feel hungry and the amount of food will become larger. If it is not controlled, it is difficult to cause obesity.

[Reminder] After donating the blood, you should pay attention to methods and methods to supplement nutrition. Do not eat high -calorie and high oil foods. The light diet is the best for the body.

Misunderstanding 4: Blood donation may infect diseases

[Truth] Blood donation will not be infected with diseases for free!

[Reason explanation] The staff of the unpaid blood donation and blood collection are all medical staff who have been trained by blood collection. The blood collection work process strictly enforces the relevant provisions of the national "Blood Station Technical Operation Regulations". The key materials used in the blood collection process: such as blood bags, reagents, reagents There are strict purchase quality control links such as disinfectant and auxiliary materials. There are strict time and scope requirements for disinfection in the process of blood collection. The blood collection materials used by blood donors are all used at one time. Essence Therefore, it is very safe to donate blood for free.

Misunderstanding 5: Blood donation will make people addictive

[The truth is white] Nonsense!

[Reason explanation] Blood donation is not smoking, let alone drug use, of course, it will not be "addictive". After the blood donation, the blood will regenerate the blood at a normal speed, and will not force the blood donor to continue to donate blood due to the "excessive" blood "produce too much". Maybe someone will ask, why do they come to donate blood again and again? Xiaobian answered you because love.

Misunderstanding 6: Blood donation can cause weak qi and blood

[Truth Daibai] You underestimated the human body's regulatory function!

[Reason explanation] Blood donation will not make people "deficiency" and "injury". The total blood volume of an adult accounts for about 7%-8%of weight, and the total blood volume of a 60 kg person is about 4800 ml, of which 80%of the blood participate in the peripheral cycle, and 20%of the blood is stored in the liver and the spleen in the liver and the spleen. Essence A person's blood donation is 200-400 ml, accounting for only 5%-10%of the total blood volume. After blood donation, the blood stored in the liver and spleen will be mobilized to ensure that the blood volume participating in the cycle will not decrease. Scientifically proves that a healthy person lost blood by 10%at a time, and it will not cause discomfort within the scope where the body can withstand. Every time the blood is vomiting new, the human body's regulation function of blood volume is also very sound. After the blood is donated, it will never produce qi and blood deficiency. In fact, when the blood donor left the blood donation scene, the body had begun to supplement the blood donated. After a few hours, the blood volume can reach the normal level without feeling uncomfortable. Blood donors can still engage in non -physical daily work on the day.

[Reminder] It is not advisable to do strenuous exercise within 24 hours after blood donation. Please take a good rest. Misunderstanding Seven: Blood donation will faint with anemia

[The truth is white] Blood will be new.

[Reason explanation] Many people think that blood is needed after blood donation, otherwise it is prone to anemia. In fact, blood donors donate blood according to regulations, which will not cause anemia. The small amount of blood dedicated by each time is regulated by the body, it will soon return to normal, and it does not affect the blood regeneration function.

[Reminder] Anemia is a disease, and people with anemia cannot participate in blood donation.

Misunderstanding 8: Blood donation can cause abnormal blood pressure

[Truth Daibai] The abnormal blood pressure of normal people is caused by tension!

[Reason explanation] Blood donation will not cause hypertension or hypotension. Some blood donors may have symptoms of high or low blood pressure after donating blood, which is caused by mental tension during blood donation. Blood donation of healthy people will not cause blood pressure fluctuations, let alone cause people to suffer from hypertension or hypotension. Some people see that blood flow can cause nervousness and fear, or people who have a fainted blood may have fainting. Experts point out that people with such situations are not suitable for blood donation.

What are the benefits of blood donation

1. Regular blood donation can prevent cardiovascular and cerebrovascular diseases

Relevant experts compared the average of 26 patients with repeated blood donation and 22 patients with acute cerebral infarction. The results showed that the whole blood viscosity, red blood cell pressure, fibrinogen, and red blood cell electrophoresis of repeated blood donors were significantly reduced than normal values. After donating blood, blood viscosity will be reduced, blood flow rate is accelerated, the ability of oxygen supply and transportation of nutrients will be enhanced, blood lipids can prevent cardiovascular and cerebrovascular diseases and reduce the incidence of cancer.

2. Blood donation can improve the function of hematopoiesis

As age increases, hematopoietic function and blood cell production rate gradually decreases. After blood donation, due to the decrease in the number of blood cells, the feedback effect on the bone marrow will be given to the production of blood cells, and blood containment can be donated according to the prescribed period, which can keep the bone marrow vigorously vitality.

3. Frequent blood donation can reduce blood lipids

Blood lipids have been at a high level for a long time, commonly known as "blood thick". The result of "blood thick" is that the fat is attached to the human blood vessel wall layer by layer, which finally causes arteriosclerosis and other diseases. Regular blood donation can reduce the viscous blood in the body, dilute the blood naturally, the blood lipids will decrease, and it will reduce the hidden dangers of arteriosclerosis.

4. Blood donation can reduce the incidence of cancer

According to relevant research reports, if the iron content in men exceeds 10%of the normal value, the chance of cancer will increase. So, how to expel too much iron to reduce the chance of suffering from cancer? Medical experts believe that the only way is to eliminate excessive iron through blood bleeding. Therefore, people with high iron content in the body can provide blood from time to time, which is good for people to themselves.

5. A moderate amount of blood donation is good for longevity

According to reports, some people compared the 332 blood donors over 66 years of age with 399 people with the same conditions. As a result, the survival rate of blood donors was significantly higher than those who had not donated blood.

6. Family free blood

For free blood donors and their direct relatives (parents, children) and spouses will get free blood cost. I can enjoy the blood donation of 5 times within 5 years, and after 5 years, I can enjoy the amount of blood, and the direct blood of relatives and spouses will enjoy the blood.

7. Free physical examination

The blood of those with free blood donation will be performed (3 times for fast inspections, preliminary inspections, and re -inspection). There are 8 inspection items, namely ABO blood type, RH blood type, hemoglobin, aminotransferase, hepatitis C, syphilis, AIDS, only all of them, all of which It can be used clinically through qualified blood.

Blood donation for free is the lofty demeanor of selfless dedication and saving wounds. While you have given a small amount of blood to save the lives of others, you will get rewards. You can donate blood for free people, self -interest, and society. Let us all dedicate a little love to help more people.
