Guidelines for reversal of anticoagulants in intracranial hemorrhage

Neurocritical Care Society and Society for Critical Care Medicine recommendations for reversal of antithrombotic agents in patients with intracranial hemorrhage

Guideline for Reversal of Antithrombotics in Intracranial Hemorrhage : A Statement for Healthcare Professionals from the Neurocritical Care Society… – PubMed – NCBI http://www.ncbi.nlm.nih.gov/pubmed/26714677

Here’s my breakdown of Table V from that article – I will try to find a way to post a downloadable PDF of this!

Antithrombotic: Timing, Antidote, Factor Replacement, antifibrinolytics

Vitamin K antagonists (warfarin) If INR > 1.3 then Vitamin K 10 mg IV, plus 3 or 4 factor PCC IV

(dosing based on weight, INR and PCC type) OR FFP 10–15 ml/kg IV if PCC not available

Direct factor Xa inhibitors: activated charcoal (50 g) within 2 h of ingestion, activated PCC (FEIBA) 50 units/kg IV OR 4 factor PCC 50 units/kg IV

Direct thrombin inhibitors (dabigatran): Activated charcoal (50 g) within 2 h of ingestion, AND Activated PCC (FEIBA) 50 units/kg IV OR 4 factor PCC 50 units/kg IV                                                                Idarucizumab 5 g IV (in two 2.5 g/50 mL vials) consider hemodialysis or idarucizumab redosing for refractory bleeding after initial administration if 1) dabigatran was taken with 3-5 half lives and NO evidence of renal insufficiency or 2) dabigatran was taken beyond 3-5 half lives WITH renal insufficiency

For other DTIs: Activated PCC (FEIBA) 50 units/kg IV OR 4 factor PCC 50 units/kg IV

Unfractionated heparin: Protamine 1 mg IV for every 100 units of heparin administered in the previous 2–3 h (up to 50 mg in a single dose)

LMWH

Enoxaparin: Dosed within 8 h: Protamine 1 mg IV per 1 mg enoxaparin (up to 50 mg in a single dose) Dosed within 8–12 h: Protamine 0.5 mg IV per 1 mg enoxaparin (up to 50 mg in a single dose)       Minimal utility in reversal >12 h from dosing

Dalteparin, Nadroparin and Tinzaparin: Dosed within 3–5 half-lives of LMWH: Protamine 1 mg IV per 100 anti-Xa units of LMWH (up to 50 mg in a single dose) OR rFVIIa 90 mcg/kg IV if protamine is contraindicated

Danaparoid: rFVIIa 90 mcg/kg IV

Pentasaccharides: Activated PCC (FEIBA) 20 units/kg IV or rFVIIa 90 mcg/kg IV

Thrombolytic agents (plasminogen activators): Cryoprecipitate 10 units IV OR antifibrinolytics (tranexamic acid 10–15 mg/kg IV over 20 min or e-aminocaproic acid 4–5 g IV) if cryoprecipitate is contraindicated

Antiplatelet agents: DDAVP 0.4 mcg/kg x 1, if neurosurgical intervention, transfuse one apheresis unit
