PLATELET TRANSFUSION Meaning and
Definition
-
Platelet transfusion refers to the medical procedure of intravenously administering platelets to a patient in need. Platelets are tiny, disc-shaped blood cells that play a critical role in clot formation, preventing excessive bleeding. They are produced in the bone marrow and circulate in the bloodstream.
Platelet transfusion becomes necessary when an individual's platelet count is too low, a condition known as thrombocytopenia. Thrombocytopenia can occur due to various reasons, such as bone marrow disorders, certain medications, chemotherapy, or as a result of blood loss or injury. When platelet levels drop significantly, the body's ability to form blood clots is compromised, potentially leading to severe bleeding or hemorrhage.
The platelet transfusion procedure involves collecting blood from a donor and isolating the platelets using a centrifugation process. After processing, the platelets are concentrated, and any unnecessary components are removed. The platelets are then suspended in a small volume of plasma or a specially designed storage solution to maintain their viability.
During the transfusion, the prepared platelets are infused into the patient's bloodstream through an IV catheter. This allows the donor platelets to help restore the recipient's platelet count and improve their blood clotting ability. Platelet transfusions are typically performed in a hospital or clinical setting, being closely monitored by medical professionals to prevent adverse reactions and ensure an appropriate response.
Platelet transfusions are a vital treatment modality for individuals with thrombocytopenia, particularly those who are critically ill or undergoing chemotherapy. They help to prevent or manage bleeding episodes and provide necessary clotting factors to protect against excessive blood loss.

Etymology of PLATELET TRANSFUSION
The word "platelet" comes from the French word "plaquettes", meaning "little plates". It was first used in medicine in the early 19th century to describe the small, disc-shaped cells found in the blood that help in blood clotting. The term "transfusion" has Latin origins, derived from the words "trans", meaning "across", and "fusio", meaning "a pouring". It refers to the process of transferring blood or blood products from one individual to another. Therefore, the term "platelet transfusion" combines these two words to describe the procedure of transferring platelets from a donor to a recipient in order to increase the platelet count in the recipient's blood.
