FFP: fresh frozen plasma
The liquid portion of the blood, separated and frozen within 8 hours of collection
It comes in 250ml bags, and it contains pretty much all the factors:
- Factor VII of the EXTRINSIC pathway (so, it decreases your PT)
- Factors XI and IX of the INTRINSIC pathway (so, it decreases your aPTT)
- Factors X and II (Prothrombin) of the COMMON pathway (so, it decreases both PT and aPTT)
Thus, it replaces all of the factors which go missing in warfarin therapy or Vitamin-K deficient liver disease. Unfortunately, there isn't much factor VIII.
Its solubility is too low at low temperatures, and FFP (once thawed) doesn't contain enough of it.
