Blood transfusion: goals and procedures

Blood transfusions can delay the death of many people who are bleeding and those who are warm to bone marrow disease or other congenital health problems.

Blood transfusion is one of the pillars of today’s medicine because it saves many lives by replacing the blood of an individual that was lost through an injury.

The first ever blood transfusion in history was carried out in the 17th century. However, it was not until the 20th century that scientists identified different blood types. Thus, up to this point, blood transfusions could be life-threatening.

Blood groups is a system for classifying blood according to the characteristics of red blood cells and their serum. When a person receives blood and a group other than the one he has, dangerous reactions are caused by this incompatibility, which can even lead to death.

This issue played a key role in the development of blood transfusion technologies, which now make them a safe and effective medical procedure. Read on to find out everything there is to know about this topic.

Blood transfusion – procedure

Blood transfusions are a routine medical procedure these days. It consists of giving the patient blood or certain blood components that are obtained from another person. There are the following elements in the blood:

  • Red blood cells, which transport oxygen and help remove waste.
  • White blood cells that help your body fight infection.
  • Platelets that are involved in blood clotting.
  • Plasma, which is the liquid part of blood.

To perform a blood transfusion, someone must donate blood first. A blood donor is obviously a volunteer who does not receive any payment for donating blood.

Donating blood is a very simple procedure that can help save another person’s life. To become a blood donor, you must be in good health, weigh over 50 kilograms, and not suffer from anemia or other blood disorders.

If you want to donate blood, you have to go to a specialized medical unit or use mobile blood donation stations during various health promotion campaigns. They usually take place in public places such as schools, universities and town halls.

Blood transfusions are generally assumed to be safe. Of course, complications can sometimes arise, but the risk of them occurring is small. Most often, there is a minor and minor allergic reaction that causes hives and fever.
