Introduction: The fresh frozen plasma (FFP) is frequently prescribed either for therapeutic or prophylactic transfusion. The international normalised ratio (INR) value of 1.50 and above is frequently reported to be a transfusion trigger for FFP prior to interventional procedure. This study aimed to evaluate the efficacy of prophylactic FFP transfusion in normalising the INR and to determine the post-transfusion outcomes. Methods: A prospective cross-sectional study involved 81 patients who received prophylactic FFP transfusion over a period of three months. All demographic, clinical data and outcomes of FFP transfusion were captured and filled in the research proforma. Results: The proportion of patients achieved posttransfusion INR below 1.51 was 30.30% (n=27). The majority of patients underwent the interventional procedures with posttransfusion INR > 1.50 (n=52) without experiencing any bleeding episodes. Overall, FFP transfusion resulted in significant median INR difference from 1.89 (IQR, 0.53) to 1.60 (IQR, 0.25); p< 0.001. The greater median INR difference was observed in group with pretransfusion INR > 2.00 and who received FFP doses between 10.00 to 20.00 ml kg-1 (p < 0.001). The INR difference showed the significant, positive correlation with pretransfusion INR values (rs= 0.83, p < 0.001) and FFP doses (rs= 0.72, p< 0.001). Conclusions: The interventional procedures were safely carried out despite abnormal posttransfusion INR. The prophylactic FFP transfusions could be avoided in patients with mild coagulopathy (INR 1.50 - 2.00) prior interventional procedures.
