==[[Cryoprecipitate Transfusion]]==
===Features===
#Cold insoluble protein fraction of FFP
#Contains: fibrinogen, vWF, and factor VIII
#1 bag (10ml) has 50-500 units of factor 8 activity
 
===Indications===
#Bleeding with fibrinogen level of <100 milligrams/dL
#Dysfibrinogenemia
#Bleeding in vWD that is unresponsive to DDAVP and Factor VIII is unavailable (can also use Humate-P, FFP doesn't work well)
 
===Dose===
#1 unit/5kg (usually 10 units are given at a time)
##Will raise fibrinogen level by 75
 
==Humate-P==
===Features===
#Contains: vWF and factor VIII
 
===Indications===
#Hemophilia A (can also use factor VIII, FFP doesn't work well)
#vWD that is unresponsive to DDAVP (can also use cryo, FFP doesn't work well)
 
===Dose===
Depends on condition and severity of bleeding

Special Considerations

Leukocyte Irradiated and Reduced (Depleted) Blood Products[2]

  • Leukocyte reduced: Prevents sensitization in patients who may require bone marrow transplant
  • Irradiated: Eliminates capacity of T-cells to proliferate (prevents Transfusion-associated graft-versus-host disease)
  • If tranfusion required for crashing patient, do not delay tranfusion of uncrossed blood to irradiate products beforehand
  • Requires minimum 25 Gy irradiation, not to exceed 50 Gy for all:
    • Packed red cells
    • Platelets
    • Granulocyte components, regardless of immunocompetency
    • First or second degree relatives, regardless of immunocompetency
    • HLA-selected components, regardless of immunocompetency
  • Irradiated products should be administered shortly after irradiation
  • Those products not used for intended recipient may be returned safely to stock for others not requiring irradiated components, though with reduced shelf life
  • Not necessary to irradiate FFP, cryoprecipitate, fractioned plasma products
Generally Accepted Indications For Irradiated Blood Products[3][4]
  • Immunocompromised stem cell recipients
  • Organ transplant recipients
  • Patients undergoing marrow transplantation
  • Intrauterine transfusion
  • Neonatal exchange transfusions
  • Premature and low birthweight neonates
  • Hodgkin lymphoma
  • Congenital cell-mediated immunodeficiencies (DiGeorge, Wiskott-Aldrich, Leiner's, 5'-nucelotidase deficiency)
  • Acquired immunodeficiencies to include:
    • Leukemia, CLL
    • Aplastic anemia
    • Neutropenia
  • Patients receiving:
    • Purine analogue chemotherapies (fludarabine, cladribine, deoxycoformicin, bendamustine, clofarabine, etc.)
    • Certain biologic immunosuppresants (alemtuzumab)
  • Donations from biologic relatives
  • Donations from HLA-matched donors
  • Genetically homogenous populations
  • Probably indicated int:
    • Hematologic malignancies other than Hodgkin lymphoma
    • Solid tumors treated with cytotoxic agents
Indications For Leukoreduced Blood Products[5]
  • Chronically transfused
  • Cardiac surgery
  • Solid organ or stem cell transplant recipients, before and after
  • Previous febrile nonhemolytic transfusion reactions
  • CMV seronegative patients at risk

Not Routinely Needing Irradiated Products

  • HIV, AIDS
  • Concurrent, non-severe common viral infection
  • Rituximab treatment
  • Routine solid organ transplant
  • Routine infant cardiac surgery
