title: Practical guidelines for the clinical use of plasma.
abstract: Despite differences in the composition of fresh frozen plasma (FFP) and solvent/detergent-treated plasma, prospective controlled clinical trials have not revealed any significant difference in clinical efficacy and tolerance between the two types of plasma. Evidence of the clinical efficacy of plasma is mainly based on expert opinion, case reports, and on controlled and uncontrolled observational studies. The application of plasma without laboratory analysis to verify the coagulopathy is normally not justified. With the exception of emergency situations when timely clotting assay results are not available, the administration of plasma in coagulopathy must be verified both clinically and by laboratory analysis before plasma is administered. The rapid infusion of at least 10 ml plasma/kg of body weight is required to increase the respective plasma protein levels significantly. Based on the present state of knowledge, plasma is indicated for complex coagulopathy associated with manifest or imminent bleeding in massive transfusion, disseminated intravascular coagulation, and liver disease. Therapeutic plasma exchange with 40 ml plasma/kg of body weight is the treatment of first choice in acute thrombotic-thrombocytopenic purpura-adult hemolytic uremic syndrome (TTP-HUS). A rare indication is the treatment or prevention of bleeding in congenital factor V or factor XI deficiency, plasma exchange in neonates with severe hemolysis or hyperbilirubinemia, and filling of the oxygenator in extracorporeal membrane oxygenation (ECMO) in neonates. Prothrombin complex concentrates should be preferred to plasma for the reversal of oral anticoagulation in emergency situations, since controlled studies have shown a minor efficacy of plasma. Side effects resulting from the administration of plasma are rare but have to be considered.
