Platelettranszfúzió

Platelettranszfúzió refers to the medical procedure of transfusing platelets into a patient's bloodstream. Platelets, also known as thrombocytes, are small, irregular-shaped cells that play a crucial role in hemostasis, the process of stopping bleeding. They aggregate at the site of injury to form a plug and release factors that initiate the coagulation cascade, ultimately leading to the formation of a blood clot.

This transfusion is typically administered to individuals with thrombocytopenia, a condition characterized by a low platelet count. This can be caused by various factors, including certain cancers and their treatments (like chemotherapy and radiation), bone marrow disorders, autoimmune diseases, and severe infections. Patients undergoing major surgery or suffering from significant bleeding also often receive platelet transfusions to prevent or manage hemorrhage.

The procedure involves collecting donated platelets from healthy individuals, processing them to isolate the platelet-rich plasma, and then infusing them into the recipient. The effectiveness of the transfusion is monitored by checking the patient's platelet count and observing their bleeding status. While generally safe, platelet transfusions carry potential risks, such as allergic reactions, fever, and the transmission of infections, although these are minimized through rigorous screening and processing of donated blood products. The decision to perform a platelettranszfúzió is based on a careful assessment of the patient's clinical condition and platelet levels.
