|Whole blood||Stored @ 4º C. Must be used within 30 minutes.|
|Cryoprecipitate||Made by thawing
FFP at 4° C, then collecting the formed precipitate. The fraction is
then stored at -30° C, with one year shelf life. It is rich in factor VIIIc,
Von Willebrand factor, and fibrinogen.|
|Fresh Frozen Plasma||Prepared from whole units of blood by
centrifugation and separation of the plasma within 6 hours of blood donation.
A unit of FFP contains 150-300 ml of plasma, stored at -30° C, and has shelf
life of one year.
Indicated for replacement of coagulation factors when coagulation
abnormalities found eg, liver disease. Starting dose is 10-15 ml/kg, and must
be group compatible. Standard locally prepared FFP is not virally
inactivated, so not as safe as saline, gelatin, or human albumin solutions.
|Human Albumen Solutions||Sterilized by filtration and heat. No
known instances of viral transmission. HAS 4.5% is used as a plasma expander,
and HAS 20% for hypoproteinaemic patients. HAS products are no more effective
than cheaper colloid and crystalloid products.|
|Platelets||Stored at 22° C in plastic bags to permit gas exchange,
and kept moving in an agitator. Shelf life is 3-5 days. For patients with acute
leukaemia or undergoing bone marrow transplantation.|
|Red Blood Cells||Available in various volumes and concentrations.|
