A great variety of patient- and product-related factors influence the outcome of platelet transfusions. The patient-related factors are numerous, either physical factors as weight and height, or related to pathological being as splenomegaly, fever, infection, disseminated intravascular coagulation, previous HLA allo-immunization, or related to the treatment, as amphotericin. Major platelet factors that are associated with impaired responses are giving a decreased dose of platelets, ABO incompatible products, and platelets stored for more than 48 hours. When trying to prevent or to treat refractoriness and to finely tune platelet transfusions, all these factors have to be taken into account, and a good coordination between the blood bank and the clinician team is essential.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...

A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...
Factors Affecting Protein-Drug Binding: Drug-Related Factors
One crucial factor in drug-protein binding is the drug's lipophilicity or its affinity for fat. More lipophilic drugs tend to have higher binding extents. For example, highly lipophilic drugs like cloxacillin exhibit substantial protein binding, with as much as 95% of the drug binding to proteins. In contrast,...
