Assessing the Rationale and Effectiveness of Frozen Plasma Transfusions: An Evidence-based Review.

Frozen plasma is a commonly used blood product. The primary indications for frozen plasma are the treatment and prevention of bleeding in patients with prolonged coagulation tests. However, there is a lack of well-conducted clinical trials to determine the appropriate indications for frozen plasma. The rationale and evidence for frozen plasma transfusions are reviewed, including the evidence or lack of evidence supporting common indications. Targeting indications in which frozen plasma transfusions are clearly not beneficial as supported by the current evidence provides an opportunity to improve the current use of frozen plasma and reduce adverse transfusion events.
