Blood transfusion is a procedure to provide blood to an individual or a patient, who has lost blood due to an injury or a surgery.
Blood transfusions are also common for people with blood insufficiency. According to the National Center for Biotechnology Information (NCBI), RBC (red blood cell) donations improve arterial oxygen content and oxygen delivery to tissues.
Experts also caution that there could be negative effects of blood transfusion if the blood is not compatible with the recipient.
In such cases the recipient’s body produces antibodies which destroy the donor’s blood cells and it leads to transfusion reaction.
This may cause rashes, itching and fever or even in severe cases injury to lungs or kidney.
In certain cases human errors during blood transfusion may also cause serious consequences for blood recipients.
Human error can be avoided by proper test for a perfect match between the blood groups of the donor and the recipient before the transfusion.
Correct labeling of the transfused blood in storage can also help to prevent such errors.
