(Redirected from Dabigatran (Pradaxa) reversal)
Contents
Background
- If aPTT is <1.5 x control, it is unlikely that significant drug effect is present
- Thrombin Time (TT) is most sensitive; normal TT excludes presence of significant dabigatran
Mild Bleeding
- Local control measures: direct pressure
- Delay next 1-2 doses OR discontinue (as appropriate)
Moderate-Severe Bleeding
- Local control measures: direct pressure/surgical intervention
- Resuscitate with intravenous fluid and / blood products
- Oral charcoal administration if drug taken <2 hours before presentation
- Hemodialysis will remove ~60% of drug taken over prior 2-3 hours
- Consider Idarucizumab (Praxbind): 5 grams IV
Life-Threatening Bleeding
- Idarucizumab (Praxbind): 5 grams IV
In addition, consider above PLUS
- Consider FEIBA[1]
- Consider Recombinant Factor VIIa (no good data)
- Consider Kcentra (PCC): 50 IU/kg IV bolus[2]
- Consider Tranexamic acid
