In vitro effects of thawing fresh-frozen plasma at various temperatures.
Thawing fresh-frozen plasma (FFP) in South Africa is uncontrolled because the plasma is issued frozen from the blood bank and thawing techniques and temperatures are at the discretion of the clinician. Following anecdotal reports of disseminated intravascular coagulation (DIC) developing in patients who received FFP thawed in an uncontrolled manner, the effects of various thawing temperatures on coagulation parameters were studied. Fifteen adult units of FFP were each divided into 4 satellite units by the South African Blood Transfusion Service before freezing at -25 degrees C. ⋯ D-dimers are elevated in thawed FFP. Fibrinogen levels are markedly decreased in FFP thawed at 60 degrees C compared with that thawed at 37 degrees C. FFP should be thawed at 37 degrees C in a strictly controlled environment.
