Podcast 749: PCC for Me?

Contributor: Nick Tsipis, MD

Educational Pearls:

  • Prothrombin complex concentrate (Kcentra)  and Vitamin K are used to reverse life-threatening bleeds in patients on warfarin (Coumadin)
  • Factors II, VII, IX, and X are included in four-factor PCC
  • PCC/Kcentra dosing is 500-2000 units based on INR and patient weight
  • PROPER3 RCT was a non-inferiority trial done to evaluate standardized dosing of PCC/Kcentra versus variable dosing based on INR and weight
  • Looked at end-points to assess hemostasis, but ultimately this trial did not show non-inferiority of standardized dosing compared to variable dosing
