Management of Trauma
Hemorrhage – Standards of Care16




Consider TXA early (bleeding or at risk)
Correct hypothermia, acidosis, hypotension
Maintain Hgb (7-9 g/dL), plts (50-100k)
Fibrinogen – maintain > 1.5 – 2 mg/dL19

Depleted earlier than blood factors


Risk factors for low fibrinogen level on admission14:


at 142% blood loss vs. 200-240% before fII, fVII critically low13
injury severity score, shock, SBP<90, prehospital fluid volume
Calcium – maintain iCa > 0.920
PCC in Trauma Hemorrhage

Evidence-supported benefit?




Thrombosis risk: low (0-1.4% for current 4fPCCs)



Lack of prospective trials demonstrating mortality benefit
Retrospective reports demonstrate decreased INR,
bleeding, need for PRBCs, stabilized blood pressure22-25
Guidelines differ16,17; local use positive
Exclusion criteria: DIC, HIT
optimal Kcentra dose: unclear. (?25-50 un/kg; max 100kg)
Possibly consider Kcentra for:



Massive hemorrhage unresponsive to conventional tx
TEG-guided: ongoing bleed with CT > 90s15
Hgb-driven “Coagulation Box” model: Hgb < 5.526
Kcentra – Nursing Considerations



Verbal orders

Clarify which “PCC”, what un/kg dose (fIX), indication

Contact blood bank or pharmacy to alert of STAT order
Administration

Concentration, dose and rate vary (~10-20 min)

Emergent reversal. Give ASAP (expires 4hrs after mixed)

Document lot numbers (blood product)

Monitor for allergic reactions and thrombosis (0.9-1.4%)
