Plasma transfusion for bedside, radiologically guided, and operating room invasive procedures

Area of Science:

• Hematology
• Transfusion Medicine

Background:

• Frozen plasma (FP) is frequently administered to correct coagulation defects before medical procedures.
• Its use is often guided by standard laboratory coagulation tests, such as prothrombin time.

Purpose of the Study:

• To evaluate the evidence supporting the prophylactic use of FP before procedures.
• To assess the effectiveness of FP in correcting coagulation test abnormalities.
• To challenge the routine pre-procedure prophylactic administration of FP.

Main Methods:

• Review of randomized controlled trial literature on FP effectiveness.
• Analysis of the predictive value of standard coagulation tests for bleeding.
• Consideration of risks associated with FP transfusion.

Main Results:

• Limited evidence supports the prophylactic use of FP.
• FP has minimal impact on correcting mild to moderate coagulation abnormalities.
• Standard coagulation tests have poor predictive value for bleeding risk.

Conclusions:

• The prophylactic use of FP lacks robust evidence of clinical effectiveness.
• Risks of FP transfusion (e.g., TRALI, TACO) outweigh benefits in many prophylactic scenarios.
• Clinical decisions regarding FP should integrate bleeding history and other markers, prioritizing therapeutic over prophylactic use.
