Recombinant Factor VIIa (rFVIIa, NovoSeven) is a procoagulant that might limit bleeding and improve trauma outcomes.METHODS:We performed a phase 3 randomized clinical trial evaluating efficacy and safety of rFVIIa as an adjunct to direct hemostasis in major trauma. We studied 573 patients (481 blunt and 92 penetrating) who bled 4 to 8 red blood cell (RBC) units within 12 hours of injury and were still bleeding despite strict damage control resuscitation and operative management. Patients were assigned to rFVIIa (200 μg/kg initially; 100 μg/kg at 1 hour and 3 hours) or placebo. Intensive care unit management was standardized using evidence-based trauma "bundles" with formal oversight of compliance. Primary outcome was 30-day mortality. Predefined secondary outcomes included blood products used. Safety was assessed through 90 days. Study powering was based on prior randomized controlled trials and large trauma center databases.RESULTS:Enrollment was terminated at 573 of 1502 planned patients because of unexpected low mortality prompted by futility analysis (10.8% vs. 27.5% planned/predicted) and difficulties consenting and enrolling sicker patients. Mortality was 11.0% (rFVIIa) versus 10.7% (placebo) (p = 0.93, blunt) and 18.2% (rFVIIa) versus 13.2% (placebo) (p = 0.40, penetrating). Blunt trauma rFVIIa patients received (mean ± SD) 7.8 ± 10.6 RBC units and 19.0 ± 27.1 total allogeneic units through 48 hours, and placebo patients received 9.1 ± 11.3 RBC units (p = 0.04) and 23.5 ± 28.0 total allogeneic units (p = 0.04). Thrombotic adverse events were similar across study cohorts.CONCLUSIONS:rFVIIa reduced blood product use but did not affect mortality compared with placebo. Modern evidence-based trauma lowers mortality, paradoxically making outcomes studies increasingly difficult. Now… Evolving plan… Viscoelastic testing • TEG or ROTEM provide a real-time graphic representation of clot formation enabling clinicians to individualize correction of coagulopathy more accurately and substantially faster than standard coagulation tests Viscoelastic Testing • Excellent to assess coagulopathy in trauma. • Performed at the bedside using whole blood (not plasma) samples so the contribution of platelets and fibrinogen to the clot kinetics can be assessed. • Provide a timely assessment of the initiation of coagulation AND of the clot formation process and the maximal clot strength • Considered the gold standard for diagnosing premature dissolution of the clot, which has been identified as an important contributor to mortality Trauma-induced coagulopathy (TIC) Multifactorial etiology: – – – – – – – – Blood loss Hypothermia Acidosis Loss coagulopathy Dilutional coagulopathy Consumption coagulopathy Hyperfibrinolysis Metabolic changes Recommendations • Stop surgical bleeding • Warm fresh whole blood or best practice component therapy in a ratio of 1:1:1:1 (plasma:platelets:cryoprecipitate:RBCs) • TXA • PCC • Fibrinogen concentrate • Point of care TEG directed care Management of Trauma Hemorrhage: Possible Role of Kcentra, a 4-factor Prothrombin Complex Concentrate Joli Dace, PharmD, BCPS Mercy Hospital and Trauma Center Objectives Define PCC and availability in US Compare Kcentra with plasma Brief overview of coagulation cascade Review possible Kcentra use in trauma: Emergent reversal of oral anticoagulants Management of trauma hemorrhage Discuss Kcentra nursing considerations What are PCCs? “Prothrombin complex concentrates” Concentrated clotting factors Derived from pooled human plasma PCC Products Available in US Therapeutic Clotting Factors Profilnine SD® II, IX, X Kcentra® II, IX, X, VII Feiba® NF II, IX, X, aVII Alternative Names 3f-PCC 4f-PCC BeriPlex® P/N (outside US) Activated 4f-PCC Factor VIII Inhibitor Bypassing Activity 3-6,18 Comparison: Kcentra and FFP Kcentra® FFP Clotting Factors II, VII, IX, X II, V, VII – XIII; fibrinogen Anticoagulants AT, heparin, protein C & S protein C & S Preparation Dilute each 500mg vial with 20mL Thaw; ABO match Volume Average 40 -100 mL/dose Average 30 mL/kg Each unit over 30-60 min Administration Rate •Weight-based (~820min) •7x faster than FFP3 Less volume and faster administration = faster Dilutional coagulopathy Risk of transfusion- Coagulation Cascade Image borrowed from AnaesthesiaUK at http://www.frca.co.uk/images/clotting_cascade.gif Action of oral anticoagulants: Warfarin inhibits factors II, VII, IX, and X (vitamin K dependent clotting factors).
