Blood transfusion is a completely ordinary process; today it is something that can save.

Story

For many centuries, people knew nothing about this procedure; only in the 17th century was a blood transfusion from a sheep to a person first arranged. But such experiments led to fatalities. It was only in 1818 that Dr. Blundell was able to make a successful transfusion from person to person. He saved a woman who had just given birth. Since 1900, donation has become something that saves life, because it was then that blood groups were discovered. And for more than a century, healthy donation has saved millions of lives: premature babies, sick people, soldiers and accident victims. This is noble and necessary.

But can everyone be a donor? Are there rules and diet when donating blood? Is it possible to make money from donation and how does the state protect donors? We'll talk about all this further.

Who can donate blood

Every person over 18 and up to 60 can become a donor. The weight of such a citizen is more than 50 kilograms.

The donor must be an absolutely mentally healthy person who is responsible for his actions and understands that he is donating blood.

A person donating blood must first of all decide for himself why he is doing this and understand that this is a voluntary and important matter.

A person must be healthy otherwise this can cause harm both to the donor himself and to those patients to whom his blood will be transfused.

If a person is going to become a donor and save someone’s life, the most important conditions for this are: adulthood, normal weight and good health.

Who cannot become a donor

Sick people are a taboo for donating blood. This applies to both physical and mental illnesses. All impossibilities to donate blood can be divided into absolute, those that do not allow you to be a donor throughout your life, and temporary, the duration of which is limited by a specific reason.

Absolute diseases are incurable diseases, oncology, chronic purulent diseases, asthma, tuberculosis, infectious diseases blood, absence of one kidney, spleen.

Before taking the test, tests for major diseases are required. If one of them is detected, the person is removed from the donation procedure. Former drug addicts and alcoholics, even if they have no data and similar diseases, become donors with caution. Such people are a risk, so donating them is enough controversial issue. In any case, they will be examined more thoroughly.

Temporary reasons for refusing to donate to a person are as follows:

Operations, abortions – 6 months.
Piercing, tattoos, acupuncture – 1 year.
Staying abroad for more than 60 days means you will not be able to donate for 6 months.
If a person has visited countries with a humid tropical climate, 36 months must pass before donation.
After typhoid fever- 3 years.
Acute respiratory diseases– only 1 month.
After inflammation and allergies – 1 and 2 months.
Blood cannot be donated until a year after birth, and only three months after the breastfeeding period has ended.
After 5 days my period ended.
The period of withdrawal from donation after vaccination ranges from 10 days to 1 year.
After taking antibiotics, 1 month should pass, and regular medications- 3 days.
After drinking alcohol, donation is prohibited for 2 days.

If the blood tests are bad, but the person does not suffer from any diseases, it is possible to become a donor after the test results are good. Usually this is a month.

Basic rules of donation

If a person decides to donate blood once or do it constantly, he must first of all healthy image life. Then it will be most useful for him and for others. Also, the most important condition should be that the person is healthy. Therefore, before the procedure:

Donation occurs in specialized centers blood transfusions, which are available in hospitals, maternity hospitals and exist as independent units. The work schedule is individual; they often take blood from 9 to 11 am. The doctor will take blood for analysis, measure blood pressure, and examine potential donor. If everything is normal, the nurse will draw no more than 500 ml of blood.

After the person’s blood is taken, he should rest a little, drink sweet tea, eat something, and should not smoke for at least an hour. The doctor can also measure your blood pressure, no need to do so sudden movements, work actively.

The state guarantees a day off on the day of blood donation, but if you wish, you can not do this and go about your normal business.

Donating blood does not affect performance or the ability to drive a car. But if the donor feels some fatigue, weakness, dizziness, it is better for him to spend this day in peace and recovery.

After the procedure, you need to drink a lot and eat nourishing, good food. The emphasis should be on meat, pomegranates, fruits, vegetables, natural juices. It is necessary to avoid alcohol for at least two days.

You can donate blood no more than once a month. But depending on what kind of blood you donate (whole blood, platelets, plasma), this period can range from 2 weeks to 3 months. The doctor will tell you this individually.

Contraindications

Blood should not be donated to people with chronic or acute diseases which were mentioned above. Also, if a person has low hemoglobin, donation will have to be postponed. If a person has a question about donating blood, it is also questionable: it is better to wait, and the doctor, most likely, will not allow it.

During an exacerbation of herpes, you cannot donate blood; first you need to be cured. In case of incomprehensible rashes or slight deterioration in health (when there are no specific complaints), it is better to postpone donation.

Ideally, the donor is a cheerful, cheerful person who is not worried about anything. You also cannot be a donor if before this the person ate a lot, drank alcohol, smoked, or was tired. There is no need to donate blood after business trips and night discos, serious physical exertion and before them. It can be harmful.

The chemical reactions that occur in the body after donating blood are mostly positive and contribute to better production of blood cells.

The main thing is to observe the measure and mode of delivery.

One of the main consequences is a feeling of happiness and joy from the fact that a good deed was done that can save more than one life. This is an increase in self-esteem, a social benefit.

Is the procedure dangerous?

It’s not dangerous, you can’t get infected with anything, the conditions are sterile. Disposable systems are used. The state provides all this.

All medications that are introduced into the donor’s body in order to take blood (for platelets, red blood cells or any other indicators) are safe.

Benefits for women

For ladies, this is an opportunity to stay young and slim, because regular donation prevents obesity and helps maintain youthful skin.

Benefits for men

Donating blood is beneficial for men because their body rejuvenates. While women become younger due to menstruation, pregnancy, childbirth, lactation, and hormones, men do not have this opportunity.

Thanks to donation, they prolong their youth, sexual activity, and become more self-confident.

For men, this is an opportunity to feel like a truly stronger sex. In addition, men are more susceptible high blood pressure, donation reduces it.

Transfusion donated blood has almost a century-old history. Despite the fact that this procedure is quite familiar to many people, the process of donating blood is still surrounded by numerous myths. Today we set out to debunk the most common of them.

Donating blood is harmful to health

The amount of blood circulating in the body of an adult is on average 4000 ml. It has been proven that a periodic loss of 12% of a given volume not only has no effect negative influence for health, but also works as a kind of training, activating hematopoiesis and stimulating resistance to stress.

The volume of a one-time donation of donor blood does not exceed 500 ml (of which about 40 ml is taken for the purpose of testing). The body quickly replaces blood loss without any negative consequences.

The blood donation procedure is painful and tiring

Modern donor centers are equipped with everything necessary to make the person donating blood feel comfortable. Unpleasant sensations donor are reduced to instant pain at the moment of needle insertion. The further procedure is absolutely painless.

Donating whole blood takes about a quarter of an hour. After its completion, the donor may experience slight fatigue, so it is not recommended to do heavy activities on the day of the procedure. physical labor or go to long trip. Donating blood components (plasma, platelets or red blood cells) can take up to one and a half hours.

There is a risk of donor infection

Many people believe that the donor runs the risk of receiving one of dangerous infections blood-borne diseases (for example, hepatitis C virus or HIV). Currently, this is absolutely excluded: only disposable instruments and devices are used for blood collection, which are unpacked in the presence of the donor, and after the procedure they are immediately disposed of.

The need for donor blood is low

Patients undergoing complex procedures require blood transfusions. surgical operations, women in labor with complicated childbirth, people with severe injuries or burns. Donor blood and its components are used in the treatment of leukemia and other oncological diseases. Exist artificial substitutes blood and plasma, but their use has a number of contraindications, as it sometimes leads to negative side effects.

To fully provide the healthcare system required quantity blood, 40-50 people out of 1000 should be donors. In some European countries this ratio has been achieved, but in Russia this indicator is still well below normal.

According to statistics, every third person on our planet needs a blood or plasma transfusion at least once in their life. At the same time, the blood of absolutely all groups is in demand, and not just rare ones, as is sometimes believed.

Anyone can become a donor

This is far from true. In Russia you cannot become a donor:

under the age of 18 or over 60 years of age;
having a body weight of less than 50 kg;
being infected with hepatitis, human immunodeficiency virus or tuberculosis;
having any blood disorders or blood diseases ( hematopoietic organs);
suffering from cancer.

Temporary restrictions on blood donation apply:

for pregnant women (blood will be accepted no earlier than one year after birth);
for nursing mothers (they can become donors three months after the end of lactation);
for women during menstruation (blood donation is allowed at least a week before the start or a week after the end);
for people who had the flu or acute respiratory viral infection less than a month ago;
for patients undergoing surgery dental intervention(at least ten days must pass);
for people who were treated with acupuncture less than a year ago, or who had a tattoo (piercing) of any part of the body;
for patients who have recently undergone vaccination (the period elapsed before donating blood depends on the type of vaccine and ranges from ten days to a year).

In addition, an exemption from donation can be obtained if tests on the day of the procedure show the presence of inflammatory process or traces of alcohol, increased body temperature or if there are serious deviations from normal indicators blood pressure. Men can donate blood no more than five times a year, and women - four times a year.

Donating blood for transfusion requires a responsible attitude. Two days before the procedure, the donor must give up alcoholic beverages. You should refrain from smoking for at least an hour before blood collection. Three days before the procedure you must stop taking medicines that reduce blood clotting (including aspirin and painkillers).

The donor should eat high-calorie foods before and after the procedure

The day before donating blood, you should not eat fatty, dairy, meat foods, eggs, smoked foods, chocolate, bananas, canned food and fast food.

It is important that the future donor does not make mistakes that could negatively affect his health. It is better to donate blood in the first half of the day. Before the procedure, you need to get a good night's sleep, have breakfast, preferring porridge or pastries and sweet tea. After donating blood, you should eat a balanced diet (at least five times a day if possible) and remember to drink plenty of fluids to replace blood loss.

Donating blood may cause weight gain

Donation itself (including regular donation) does not affect body weight in any way. There is a risk of gaining weight for those people who, having misunderstood the recommendations for nutrition, begin to intensively consume high-calorie foods to donate blood and cannot stop in time.

Donation is bad for your appearance

Some women are hesitant to donate blood, believing that this will negatively affect their complexion and skin elasticity. In fact regular donation activates the work of the hematopoietic organs, causes the blood to renew itself faster, and has a beneficial effect on the functioning of the immune, cardiovascular and digestive systems.

Donors, as a rule, do not have problems with the tone and color of their skin. They are cheerful, fit, active and have a positive attitude.

Regular donation is addictive

About addiction in this case can only be said in the sense of increased resistance of the body to various stresses, diseases and negative impact external environment. Thus, regular blood donation teaches the body to quickly replenish blood loss, which can play a positive role in the event of an injury or illness from which no one is immune.

Donation has been clinically proven to reduce the risk of developing cardiovascular pathologies. Some men note that regular blood donation has a positive effect on potency.

For a successful blood transfusion, the donor and recipient must be of the same nationality

The statement has nothing to do with reality. The compatibility of the donor and the recipient (the person to whom the blood is transfused) depends solely on the composition of the blood, that is, the presence or absence of certain proteins in it. For transfusion, the compatibility of blood groups (AB0 system) and Rh factor is important. These indicators are distributed almost equally among different races and ethnic groups.

With suitable protein composition Donor blood can be transfused into a recipient regardless of gender, age or nationality.

Donor blood transfusion has a history of almost a century. Despite the fact that this procedure is quite familiar to many people, the process of donating blood is still surrounded by numerous myths. Today we set out to debunk the most common of them.

According to doctors, is it useful to donate blood? How does this procedure affect a person’s well-being? What should those planning to become a donor consider?

Does this procedure seriously harm the body?

There is heated debate about whether donating blood is harmful. Driving boards cannot determine whether it is worth agreeing to mark the donation and transfusion in the event of a serious accident.

If we talk only about the health of the donor, then the donation of biomaterial is considered safe procedure. An exception may be cases when the event is not carried out according to the rules, too often, or too much biological fluid is taken.

Donating blood is harmful if more than 500 ml of donor fluid is taken from a person at a time. In this case, the procedure can have a negative effect on the body.

When asked whether it is beneficial for women to donate blood, the answer is ambiguous. It is important to consider several nuances. It is worth noting that the law regulates the frequency of blood fluid donation. A woman should not agree to this procedure more than four times a year.

Is it beneficial for men to donate blood? In order not to cause damage to the body, it is important not to allow biomaterial to be taken more than 5 times a year and to donate no more than a volume at a time.

When does recovery occur?

Some people do not know whether it is possible to donate blood and how such a procedure affects their well-being. Although a person sometimes feels noticeably weak and tired in the first few hours or even days, this condition soon passes. What is this connected with?

The body of any person is capable of recovery. If no more than 450 ml is taken at a time, this volume is replenished in approximately 2-4 weeks. For the procedure, biomaterial is taken from a vein.

Precautionary measures

Before determining whether donating blood is beneficial for the body, it is important to consider some pitfalls and understand when to be careful with such a procedure.

If you agree to take biomaterial when the procedure is contraindicated, you can cause serious harm to your health. Donating blood: good or bad? It all depends on the person’s health status before the procedure.

Donating donor biomaterial is contraindicated in the following situations:

If the person wishing to donate blood has recently consumed alcohol large quantities or long time abuses it, the procedure should be abandoned. If hepatitis is suspected, the donor fluid becomes a source of infection for the future recipient.

Important! IN last years Hepatitis virus infection often occurs through donated blood. There is no laboratory equipment capable of 100% accurately determining the absence of this virus. The risk of infection can be reduced to zero only if there is no transfusion of human blood or plasma.

If a woman has begun menopause, it is also better not to donate biomaterial. Why? During this period, her body is weakened, so some negative process may be triggered by exhaustion protective forces caused by blood donation.

A cold is another contraindication to manipulation. Athletes should approach the process with caution. Of course, they can donate biomaterial. However, after this you will not be able to withstand high physical activity for some time.

Any colds are considered a contraindication. As long as a person is sick, there is a constant risk of transmission of infection through the blood to the recipient.

Allergy sufferers should also be careful. Specific antibodies can be transmitted through blood. As a result, what was an allergen for the donor will affect the well-being of the recipient.

Iron deficiency is also considered a contraindication to collecting biomaterial for donation. A person already lacks the formation of new red blood cells, which is why anemia develops. Taking blood can only make you feel worse.

Other contraindications

There are other situations when the procedure is prohibited. Is it necessary to donate blood, and why do it? Sometimes the cause of infection with serious diseases lies in the entry of the pathogen into the body through donor blood. Even healthy man may not suspect that he is a carrier severe infections. Will this blood become life for someone or fatal disease, no one can predict.

Pregnancy is considered a separate contraindication. The procedure is not performed in the first, second or third trimester. If screening does not show pathologies, blood sampling is still contraindicated. At this time, a woman should think about the well-being of her unborn child, and not about donating biomaterial. During the period of breastfeeding, such manipulations should also be avoided.

Even those who previously tolerated blood sampling well may sooner or later experience complications. For example, men may notice that after the procedure, potency decreases for some time.

Advantages

At the same time, the procedure is practically painless. The injection made when taking blood fluid is no more painful than a regular mosquito bite. According to some doctors, taking donor blood fluid is good prevention from some diseases of the hematopoietic organs.

The advantages include the fact that various fractions are made from several grams of donor blood, isolating proteins that can fight various diseases, for example, immunoglobulins.

Blood donation: benefit or harm?

There has been debate for quite some time about the benefits of losing a certain amount of blood. But doctors are in a hurry to reassure everyone and confidently assert that it is useful to donate blood after a certain time and under certain restrictions. In this case we're talking about that blood is donated by certain rules, after examining the donor.

The main thing is to carry out all the preparatory measures that will allow the fence to be carried out for the benefit of the person and without harming him. This is especially true for women, because women need to donate blood a little less often, since their loss is taken into account due to monthly menstruation.

Before delivery

As has already been noted above, preliminary preparation is needed before taking the analysis. Be sure to check for Rh factor and determine the group. It's also useful to do general analysis blood on possible content viral cells. It can be HIV infection, hepatitis B and C, syphilis and others. Regardless of who needs this help, age does not matter. Therefore, older people can also donate blood for children. Our plasma is ageless.

Why can't you donate blood without additional examinations? This is explained by the fact that our body may contain cells that are dangerous to the patient’s health and thus can cause harm to the donor. Therefore, a preliminary examination and testing is simply necessary. You will also need to go through general examination doctor to determine general condition health, it may turn out that your blood cannot be taken due to certain indicators. This is especially true for those who have had operations, have tattoos on their bodies, or piercings.

In order to become a donor, you also need a certain weight – at least 50 kilograms. In particular, this applies to children who are low in weight and cannot be tested for a donor. Also, who else needs to be careful is pregnant and breastfeeding women. In some cases, it is still useful to make a fence, but not in large quantities.

Does blood sampling have a beneficial or harmful effect on the body?

Many people are interested in this issue, and some are even indignant - why not? It must be said that the information that periodically donating blood is useful has been confirmed a long time ago. Also, in more serious situations, many do not even think about their health, because for some this blood is much more important. Therefore, the question of whether it is harmful to donate blood is completely absent.

And so let’s determine what exactly are the advantages of periodic delivery:

Stimulates overall recovery of the body and normalizes blood circulation;
prevention of cardiovascular diseases occurs;
the body activates independently and develops the immune system, because in this case the reception special drugs will be harmful compared to transfusion;
the liver unloads on its own and the work of the spleen is prevented - why not do this without drugs;
If you periodically donate blood, the body will independently resist subsequent excessive bleeding.

Why still can’t donate blood often?

Despite the many advantages of this procedure, there are some limitations:

It is not recommended to donate blood to men more than 5 times a year, and to women more than 4 times;
you can't burden yourself physical activity two days before the procedure;
there are some dietary restrictions - do not eat fatty and fried food, alcohol, eggs. It is better to donate blood after a diet;
it is harmful to carry on after the collection active image life, in particular, we are talking about the fact that it is better to relax and not go on long journeys.

Is it free or paid to donate blood?

It is worth noting that today (03/2/2014) all such procedures should be carried out free of charge. IN mandatory this should occur at designated transfusion sites with prior examination by a physician. Thus, the doctor must determine whether it is harmful for you to donate blood or not. It is not recommended to agree to a fence without tests and examination.

We can confidently say that today donating blood is free, especially since after the procedure you yourself should receive a reward and additional days off for rehabilitation. As for the size of the remuneration itself, this is a matter for local authorities. Therefore, do not be afraid and, if necessary and able, feel free to donate blood in order to help people who really need donation. Your doctor should warn you about rehabilitation period, balanced diet and other features.

Now you can make your own conclusion about whether it is useful to donate blood periodically, in order not only to help the patient, but also your body with recovery. You will become an irreplaceable donor, because sometimes things happen rare group and requires careful selection the right person. This also applies directly own health, because in this way you help cleanse blood vessels, increase immunity and restore the overall balance of your body.

Please note that quite often people themselves are called for the fence and this really helps. After all, not everyone just wants to go into the hospital and get a transfusion. This requires compelling reasons. And finding a donor is exactly what you need. You get a double benefit from this - you help the patient and your body. In just half an hour, you can become a little healthier, and a sick patient gets a chance to live.

Is it dangerous to be a donor?

A new study has confirmed that blood donation is not harmful to health and does not cause cancer. "You don't have to worry that if you donate blood frequently, you'll get cancer," said study leader Gustave Etgarn from Stockholm. “In fact, donating blood can even be beneficial.” A new study has confirmed that blood donation is not harmful to health and does not cause cancer. "You don't have to worry that if you donate blood frequently, you'll get cancer," said study leader Gustave Etgarn from Stockholm. “In fact, donating blood can even be beneficial.”

“People who donate blood frequently are less likely to develop cancer than those who don’t,” Dr. Etgarn and colleagues wrote in the Journal of the National Cancer Institute.

However, due to the fact that general health donors tend to have better health, then frequent blood donations can mask emerging diseases. The scientist also said in his interview that there are certain prerequisites that donating blood can affect health.

Loss of blood from the body leads to activation bone marrow, which stimulates the active production of blood cells. Increased cell division, so-called “mitotic stress,” may increase the likelihood of malignant disease of the hematopoietic system. Blood loss causes immune changes in the donor's body, and this can cause cancer.

The positive side of donation is the fact that iron reserves in the body are reduced. Excess iron can cause various diseases, so people who donate blood frequently can improve their health by reducing these excess supplies.

Dr. Etgarn and his colleagues decided to find out how donation actually affects the human body. They examined archival data from Swedish and Danish blood banks, which contained data on more than 1 million donors from 1968 to 2002. The researchers concluded that there is no link between frequent blood donation and risk cancer diseases. Moreover, among male donors there was a decrease in cancers such as liver, lung, colon, stomach and larynx cancer. The risk of cancer decreased the more often men donated their blood. As already mentioned, scientists explain the reduced risk of cancer by a decrease in iron reserves in the body.

However, among donors more often than among ordinary people non-Hodgkin's lymphoma occurred ( malignant disease blood). However, this disease was recorded only in those donors who donated blood before 1986. Therefore, these data should be treated with caution, Dr. Etgarn said.

Additional study of the reasons for the development of lymphoma in donors is now required. Since many people donate their blood, the message that it may be in any way dangerous should be seriously examined. Still, Dr. Etgarn believes that “our study shows quite clearly that donors do not have an increased risk of developing malignant diseases.”

The Moscow Main Territorial Administration (MSTU) of the Central Bank of the Russian Federation called on banks to strengthen control over the condition of banknotes and coins arriving at the cash desks of credit institutions. On this occasion, a circular was sent out, which refers to the discovery of signs of radioactive contamination of banknotes in packages that banks hand over to MSTU branches, writes Novye Izvestia.

More than 1,500 people have died from a cholera outbreak in Nigeria this year, Reuters reports. That is more than four times the death toll released by the government in August, the UN said in a statement on Monday.
