Crit Care larger volumes of transfused plasma. 14 FPP was also associated with an increased risk of acute lung injury in patients in the intensive care unit 15 and of multiple organ failure in patients with critical injuries. 16 In a study of patients undergoing coronary artery bypass, transfusion of FPP correlated with a higher long-term mortality. 17 Finally, FPP showed to be ineffective to correct mildly prolonged coagulation values in non-bleeding patients; 18,19 however, another study showed that plasma therapy reduced mortality rates in cases of massive transfusions when it was implemented at an early stage. 20 These results were not verified by a meta-analysis of randomised controlled trials evaluating FPP for anticoagulation reversal or for the prevention and treatment of bleeding associated with invasive interventions or specific pathologies. 21 Whereas the transfusion of FPP is associated with increased incidence of nosocomial infections in patients undergoing surgery for conditions other than traumatic injuries, 22 goal-directed therapy with coagulation factor concentrates has a lower potential for infectiousness and incidence of multiple organ failure compared with FFP, although no significant differences in mortality rates have been observed with the two approaches. 23 Prothrombin complex concentrates (PCCs), traditionally used in the treatment of haemophilia and other congenital bleeding disorders, are recommended in the emergency reversal of vitamin K-dependent oral anticoagulants. 2 A recent systematic review and meta-analysis of randomised and observational studies demonstrated a lower rate of all-cause mortality and risk of post-transfusion volume overload, accompanied by rapid INR reduction, compared with FFP in patients receiving treatment with warfarin who experienced a major bleeding event or who needed urgent surgery. 24 Unlike FPP, PCCs require small infusion volumes and can be promptly administered to patients without the need for blood group matching or thawing, which can be particularly relevant is urgent cases of patients with intracranial haemorrhage who receive oral anticoagulants, 25 but their use is associated with an increased risk of thrombosis and should therefore be carefully analysed for trauma patients. Fibrinogen supplementation, by contrast, is superior to FPP in the reversal of severe trauma- induced coagulopathy, but because fibrinogen is a critical haemostatic factor for efficient local clot formation it reaches its critical lower reference values before all the other factors. 26,27 Rescue therapy with recombinant activated FVIIa, commonly used in the treatment of haemophilia, may be considered for life-threatening bleeding events that cannot be controlled with standard surgical interventions or coagulation therapy, although its cost and risk of arterial thromboembolic events associated with higher doses, especially among the elderly, should be taken into consideration in treatment decision making. Finally, replacement therapy with FXIII concentrate does not seem to have an effect in reducing transfusion needs. 2,4 Med 2006;34(6):1608–16. 7 Weber CF, Zacharowski K.

Increased 14 HHE 2018 | hospitalhealthcare.com Conclusions In light of the current evidence in the management of perioperative bleeding, prompt and goal-directed therapy is the key element in the implementation of haemotherapy for patients with coagulopathies. This involves a rapid and comprehensive diagnosis of the existing coagulation deficits and the use of coagulation factor concentrates to restore function. Nevertheless, the question of superiority of factor concentrates versus. allogenic blood products cannot be definitely answered at this time because allogenic blood products are still indicated for particular conditions, mainly for the management of extensive blood loss with massive transfusions, and in situations where the use of factor concentrates cannot correct the underlying pathology. In conclusion, goal-directed therapy with coagulation factor concentrates is preferred, but in some rare cases clinicians may have to resort to allogenic blood products. of fresh frozen plasma vs coagulation factor concentrates on morbidity and mortality in trauma-associated haemorrhage and massive transfusion.
