Severe post-traumatic bleeding remains a major challenge in trauma management . The effectiveness and safety of PCC in the treatment of major traumatic bleeding is controversial, and the indications for use are not clear. Studies on the status of PCC use and the efficacy evaluation of PCC adhere to recommendations are lacking.

Post-traumatic severe bleeding and associated traumatic coagulopathy remains a challenge.

The use of prothrombin complex concentrate (PCC) is being explored in the management of on-going coagulopathy following trauma, with the cited purpose of boosting thrombin generation. Clinical data on the efficacy of PCC as part of a coagulation factor concentrate-based haemostatic strategy showed initial promising results in retrospective studies and meta-analysis.

Certainly, the utility of PCC was a residual question in the management of traumatic coagulopathy. Uncertainty remains on the indication of use.The 2019 guideline on management of major bleeding and coagulopathy following trauma suggest that PCC should be administered to the bleeding patient based on evidence of delayed coagulation initiation using VEM, provided that fibrinogen levels are normal. The recommendation Grade is 2C.Studies on the status of PCC use and the efficacy evaluation of PCC adhere to recommendations are lacking.
