Platelets Relative CIITP
Platelets Absolute CITTP, HIT
Platelets Storage20-24 C with constant gentle agitation 5 days (may go 24 hours w/o agitation) 4 hours after pooling
Pooled platelets in closed system5 days or shortest outdate of RDP in pool, room temp
Apheresis plateletsPlts. (> 3 x 10^11), reduced amount of plasma, WBC (< 5 x 10^6 if leukoreduced), RBC (< 2 mL) 300 cc
Apheresis platelets Isame as random donor plts. Minimizes alloimmunization
Apheresis platelets storage20-24 C with constant gentle agitation 5 days (may go 24 hours w/o agitation)
FFP Imultiple factor deficiencies, PT/PTT > 1.5x midrange of normal
FFP Relative CIIgA def. pts
FFP storage-18 C 1 year, 7 years if stored at -65 C, expires in 24 hours after thawing (relabeled as "thawed plasma" after 24 hours)
Thawed plasma shelf life5 day, refrigerated
CryoCold insoluble portion of plasma; must have 150 mg of fibrinogen and 80 IU of fVIII; also has fXIII, vWF
Cryo PreparationFFP thawed and centrifuged at 1-6 C. After removing thawed plasma, precipitate must be placed at  -18 C to make cryo 15 cc

Question Answer
CCI (BSA x Observed platelet increment) / Number of platelets transfused
BSA(Height in cm x weight in kg / 3,600)^1/2
Number of platelets transfused1 pheresis unit has 3x10^11 platelets, 2 for 4 random donor units, 3 for 6 random donor units
CCI cut offCCI > 10,000/uL is considered adequate. CCI of 5,000 considered evidence of refractoriness

warfarin reversal

Question Answer
INR < 5lower the dose
INR 5-9 with no significant bleedhold warfarin
INR 5-9 with increased risk or minor bleedinghold warfarin, give vita K 1-2.5 mg orally
INR 5-9 with scheduled surgerygive vita K 2.5-5 mg orally, expect drop in INR in 24 hours, if not give lower dose vita K 1-2.5 mg
INR >9 with no bleedgive vita K 2.5-5 mg orally, monitor for INR in 24 hours, if not give additional vita K
INR > 20give vita K 10mg slow IV infusion, supplement with FFP as needed, consider prothrombin complex concentrate (FVIIa) for life threatening bleeding
