BLOOD TRANSFUSION

Abstract

Blood transfusion is one of the most important and widely used medical procedures worldwide. It involves the transfer of blood or its components from a healthy donor to a patient in need. Blood transfusions are essential in surgeries, trauma care, treatment of chronic illnesses such as anemia, hemophilia, and certain cancers, as well as in emergencies caused by accidents or childbirth complications. The procedure requires careful donor selection, blood typing, and crossmatching to avoid adverse reactions. Despite its benefits, blood transfusion carries risks, including immune reactions, infection transmission, and other complications. This article reviews the methods, benefits, risks, and modern innovations in blood transfusion practices, highlighting its role in saving lives and improving patient outcomes.
