Blood TransfusionA blood transfusion is a medical procedure that involves the transfer of blood from one individual to another. Previous blood transfusion practices used whole blood as the transfusion product, that is, all components of the blood. But modern technology and discoveries allow doctors to transfer specific blood components such as red blood cells or plasma. Attempts at blood transfusions date back to the 17th century, but it wasn't until an Austrian-American doctor discovered blood types that blood transfusions became more stable and safe. Blood transfusion is important both scientifically and medically, since a blood transfusion can save the life of the patient who has lost a lot of blood and prevent his heart from working too hard due to lack of blood. Various blood transfusion applications like this will save patients from the clutches of death. The applications of science in blood transfusion and the importance of blood transfusion for us humans will be covered. Last but not least; the problems that societies have faced with regards to blood transfusions will be analyzed in depth. A blood transfusion requires delicate scientific knowledge, otherwise many factors in the transfusion will go wrong, such as infections or blood allergies. One of the main elements that determine the safety of a blood transfusion is the blood type of both the person donating the blood and the person receiving the blood. In 1901, an Austrian American physician and biologist Karl Landsteiner discovered the different blood groups and organized them into the ABO blood grouping system. The theory is that there are four types of blood: A, B, AB and O; and that a person can only...... middle of paper...... blood transfusion is death in extreme cases. However, to conclude, the discovery of blood transfusion represents a major breakthrough in medical science as well as in the sustained campaign to extend human lifespan. Especially after the discovery of blood group types, blood transfusions have helped countless patients and the possibility of something going wrong, such as infection, passed through blood close to 0. The importance of blood transfusion is recognized in around the world after observing the wonders it could do to bloodless people. Although some religious groups do not accept blood transfusion, most people will recognize the usefulness of blood transfusion, especially in life-or-death emergency situations. Patients who survived car accidents and blood diseases owe many thanks to the discovery and improvement of blood transfusion.
