Platelet transfusion. Platelet transfusion, also known as platelet concentrate, is used to prevent or treat bleeding in people with either a low platelet count or poor platelet function. [1] Often this occurs in people receiving cancer chemotherapy. [1] Preventive transfusion is often done in those with platelet levels of less than 10 x 10 9 /L ...
Platelet transfusion refractoriness. Platelet transfusion refractoriness is the repeated failure to achieve the desired level of blood platelets in a patient following a platelet transfusion. The cause of refractoriness may be either immune or non-immune. Among immune-related refractoriness, antibodies against HLA antigens are the primary cause.
Plateletpheresis (more accurately called thrombocytapheresis or thrombapheresis, though these names are rarely used) is the process of collecting thrombocytes, more commonly called platelets, a component of blood involved in blood clotting. The term specifically refers to the method of collecting the platelets, which is performed by a device ...
Disseminated intravascular coagulation (DIC) is a condition in which blood clots form throughout the body, blocking small blood vessels. [1] Symptoms may include chest pain, shortness of breath, leg pain, problems speaking, or problems moving parts of the body. [1] As clotting factors and platelets are used up, bleeding may occur. [1]
Intraoperative blood salvage (IOS), also known as cell salvage, is a specific type of autologous blood transfusion. Specifically IOS is a medical procedure involving recovering blood lost during surgery and re-infusing it into the patient. It is a major form of autotransfusion. It has been used for many years and gained greater attention over ...
Platelets or thrombocytes (from Ancient Greek θρόμβος (thrómbos) 'clot' and κύτος (kútos) 'cell') are a blood component whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot. [1] Platelets have no cell nucleus; they are fragments of ...
Perfusion scanning. Perfusion is the passage of fluid through the lymphatic system or blood vessels to an organ or a tissue. [1] The practice of perfusion scanning is the process by which this perfusion can be observed, recorded and quantified. The term perfusion scanning encompasses a wide range of medical imaging modalities.
002923. [edit on Wikidata] An exchange transfusion is a blood transfusion in which the patient 's blood or components of it are exchanged with (replaced by) other blood or blood products.
