Something About Fresh Plasma

The phrase fresh frozen plasma (FFP) refers to the liquid portion of human blood that has been frozen and preserved after a blood donation[1] and will be used for blood transfusion. The capitalized phrase Fresh Frozen Plasma in the United States can refer to the fluid portion of one unit of human blood that has been centrifuged, separated, and frozen solid at −18 °C (−0 °F) or colder within eight hours of collection. The phrase "FFP" is often used to mean any transfused plasma product. The other commonly transfused plasma, PF24, has similar indications as those for FFP with the exception of heat-sensitive proteins in the plasma such as factor V.

The use of plasma and its products has evolved over a period of four decades. The use of FFP has increased tenfold from between the years 2000-2010 and has reached almost 2 million units annually in the United States. This trend may be attributable to multiple factors, possibly including decreased availability of whole blood due to widespread acceptance of the concept of component therapy. FFP contains the labile as well as stable components of the coagulation, fibrinolytic and complement systems; the proteins that maintain oncotic pressure and modulate immunity; and other proteins that have diverse activities. In addition, fats, carbohydrates and minerals are present in concentrations similar to those in circulation. Although well-defined indications exist for the use of FFP in single or multiple coagulation deficiencies, indications for many of its other uses may be empiric.
