Steps to donate blood in Uruguay

To donate blood we must have the following considerations before, during and after donating:

Before donating

Your pulse and blood pressure will be checked and your hemoglobin level will be measured in a small sample of blood taken from one of the fingers of the hand with single-use, sterile, disposable material.
If everything is favorable, you can donate, otherwise, the health personnel will inform you immediately and advise you on the possible anomaly found.

It is a really easy process, so the most important thing is the desire to want to help those who need it most. As recommendations, we advise you to have rested and sleep well the night before, and not come fasting. If you have a tendency to have low iron levels, you can prepare yourself by eating iron-rich foods such as red meat, liver, fish and eggs. Also legumes and nuts are rich in this nutrient.

during the donation

The extraction is usually carried out from a vein in the elbow flexure, lasting about 10 minutes, until obtaining approximately 450 ml. Of blood. Sterile, single-use and disposable material is used at all times, so there is no risk of contracting any disease during blood donation.

At the same time, blood samples will be taken which will later be rigorously analyzed to rule out any possible communicable disease. In case of finding any positive result, you will be informed of it and you will be excluded for future donations temporarily or permanently as appropriate. Likewise, your drawn blood will be withdrawn from use.

after donating

After the donation it is necessary to remain at rest for about 10-15 minutes.

You should drink plenty of fluids and avoid smoking and drinking alcohol for two hours after donating.

You should avoid hot environments or sports or strenuous activities at least until the next day

After donating, most donors are fine, however you need to be aware of some of the Adverse effects that may occur during or after donation.

  1. Dizziness or vasovagal reaction.

    It is a rare problem, easy to recover from, it is more frequent in the 1st donation. It is accompanied by a drop in blood pressure, and is prevented by drinking plenty of fluids before donating.

  2. Puncture point problems.

    During the donation we can find problems at the puncture point that lead to the formation of a hematoma. This problem may be due to the channeling of a vein that is too fine. When this happens, we cannot continue the donation. The nurse will recommend the appropriate measures for the care of the affected area. It is important not to carry weight and maintain a compression bandage for 24 hours to avoid the extension of the hematoma, which in some cases can be severe.

  3. nerve injury

    It is a very rare side effect that occurs if a nerve root adjacent to the puncture site is accidentally punctured. In these cases, the donor usually reports hand numbness, which resolves quickly and spontaneously.
    In the event that after the donation, you present some complication or disease or remember any relevant information not stated during the interview, it is very important that you inform us about it in order to assess whether the products obtained are unsuitable for transfusion.

Who can’t donate blood?

For no reason should patients with insulin-dependent diabetes, who have injected drugs through the skin or veins, donate blood. Carriers of infections such as AIDS, hepatitis B or C, or Chagas disease cannot be donors either.

People who have chronic kidney, lung, heart and/or high blood pressure diseases, among others, in addition to those who are being treated for epilepsy, cannot donate blood.

Finally, those who have had risky behaviors in their sexual behavior should not donate blood.

Benefits of donating blood

  • Free health check:
    You can only donate blood if you are completely healthy and free of any type of disease. . Before donating blood, you have to go through some simple tests that are totally free. For example, you can know if you have too high or low blood pressure, detect anemia, hepatitis or others. This will help diagnose any possible disease in its early stage, before it develops. In addition, you can choose to be informed if they find any abnormalities.
  • Reduces the risk of heart disease:
    Regular blood donations help keep iron levels in the body under control, especially in men. This has been shown to reduce heart disease. Although iron is an essential element for the proper functioning of the body, excess iron accumulation can lead to excessive oxidative damage, which is the main culprit in premature aging, heart attacks , strokes, etc. According to the data, if you donate blood every 6 months for about 6 years, you can reduce the probability of contracting cardiovascular disease by up to 90%.
  • Burn calories:
    A blood donation helps burn 650 kilocalories, thus helping you lose weight. However, blood can only be donated once every two to three months. This will depend on your state of health and your iron and hemoglobin levels.
  • Promotes the elimination of harmful substances:
    Although a person suffering from cholesterol, for example, will not completely eliminate triglycerides, they do have the opportunity to regenerate lower values ​​more quickly. The concentration in blood will be the same, but if the donation is followed by an adequate diet it will be easier to achieve improvements than if you had not donated blood.
  • Reduces the risk of cancer:
    According to a study published in the Journal of the National Cancer Institute, iron increases free radical damage in the body and has been linked to increased risk of cancer and premature aging. People who donate have lower iron levels and therefore a lower risk of cancer.
  • Higher quality and duration of life:
    According to a study in Health Psychology, those volunteers who altruistically donated blood had a significantly lower risk of mortality. These could even reach 4 more years of life, compared to those who did so for other reasons, such as economics.
    As for the side effects that could appear, they are quite infrequent, such as: dizziness or a bruise from a bad puncture, but nothing serious. Even so, if the person meets certain parameters and those conditions are ensured, there will be no negative effect on their health.
  • increase your empathy
    Various scientific studies show that the act of donating activates oxytocin, the pleasure hormone, therefore our reward mechanism is activated.

How much blood is donated?

Doubts about the amount of blood that a person can donate were explained by the national coordinator of the hemotherapy program and blood banks of the Ministry of Health (Minsa) ensured that a person between 65 and 70 kilos you can donate a little less than half a liter of blood.

We donate 450 cubic centimeters of blood, a little less than half a liter, which allows to prepare three components: red blood cells, plasma and platelets. This does not weaken the person because the amount of blood that an average person between 65 and 70 kg in weight can donate is medically proven. This is not going to affect you at all.

How often is blood donated?

Taking blood for donation can be done Every two monthswith a maximum of four donations a year in the case of men and three donations in the case of women. This difference by gender has been established by the blood that women already lose periodically due to menstruation.

How much blood is donated depends on the donor’s weight. By law, no more than 13% of your blood volume can be removed. But the usual thing is to take out 450cc which is the capacity of standard bags and anyone over 50Kg can donate that amount without prejudice.

It is an aspect in which the bodies in charge are very strict and therefore Is there a blood donor card?. Through it, the donor can see how often blood can be donated. And the professionals who work in the places where you donate blood, check that the established deadlines are being met.

There is no discrimination of this type related to the blood types. Although some are less frequent, the deadlines must be respected equally.

Why donate blood?

Blood donations help save lives and improve health. Here are some examples of people who need transfusions:

  • Women with obstetric complications (ectopic pregnancies, bleeding before, during or after childbirth, etc.);
  • Children with severe anemia, often caused by malaria or malnutrition;
  • People with severe injuries caused by natural and man-made catastrophes; Y
  • Many patients undergoing complex medical and surgical interventions, and cancer patients.

Blood is also required for periodic transfusions in people affected by diseases such as thalassemia or sickle cell disease; likewise, it is used to make various products, for example coagulation factors for hemophiliacs.

There is a constant need for regular donations, as blood can only be kept for a limited time and then it is no longer usable. Regular blood donations by a sufficient number of healthy people are essential to ensure the availability of safe blood when and where it is needed.

Blood is the most valuable gift we can offer another person: the gift of life. The decision to donate blood can save a life, or even several if the blood is separated into components – red blood cells, platelets and plasma – that can be used individually for patients with specific diseases.

Do they pay to donate blood?

In Uruguay, blood donations are not paid for or collected, but whether or not the storage and transportation of the blood to where it is needed generates expenses, expenses that will have to be paid for by the institution where the donation is needed.

Said cost cannot be disputed directly between merchants or in a global market as an item since this would lead to very serious legal charges.

Risks of donating blood

In itself there is no risk of donating blood, other than due to some negligence of those in charge of treating the rest, there is no possibility of you getting infected or causing any damage. The system of interconnected bags and the rest of the material is for single use, and after this, it is completely useless.

Even for the safety of the recipient of the donation, there is the first security barrier that would be the questionnaire that is carried out at the beginning of the process.

Because although the analyzes are very reliable, there is a moment called the ‘window period’ in which a certain disease has not manifested itself. In this period, the person is infected but the antibodies to fight the infectious agent have not yet appeared. This phase cannot be detected in the laboratory and that is why it is important that you be clear and sincere when stating whether or not you have participated in practices considered risky for donation.

in this the interval of time elapsed between an infection produced by any pathogenic agent and the capacity of detection by current diagnostic methods. This means that during a variable period of time depending on the case, «contaminated» blood could theoretically not be detected before being used on a patient.

What is done with the blood that is donated?

Blood is processed within 24 hours of donation, as follows:

  1. Division:

    It consists of the separation of blood into its three fundamental components; concentrated red blood cells, plasma and platelets.

  2. Red blood cells:

    They carry oxygen. They are used to treat acute anemia secondary to blood loss after surgery or trauma and chronic anemia. Store at 4ºC for up to 42 days.

  3. Plasma: It is the liquid part of the blood and contains the coagulation factors. It is used to correct bleeding problems due to coagulation defects. It is also used by the pharmaceutical industry to make vaccines and some medicines. Stores up to 2 years frozen.
  4. Platelets:

    They are small cellular corpuscles that initiate the coagulation process. They are mainly used in patients with cancer and organ transplants. It is stored at 22 degrees for 7 days.

  5. Analysis:

    At the same time that the blood is divided, tests are carried out to identify the blood group, Rh, and detection of infectious diseases. HIV, HBV, HCV, Syphilis.

Donating blood implies a highly pleasant and necessary well-being and health benefit, it contributes to recurring accidents which require blood transfusions or diseases in which blood components are needed in greater quantities. Either out of consideration or support, DONATE BLOOD.

We hope we have fully clarified the Requirements to donate blood and other necessary aspects.
