Plasma Transfusion History

1. Blood Substitutes: Salt Solutions/Ringers 18592. 1870s Bowditch and Luciani infused Sheep Serum into Frog Heart3. By 1884 Pre-Clinical Studies established the presence of vaso-active substances released by blood clotting4. 1917-19 Replace 96% of dog blood with horse plasma5. WWI Advantage of citrated plasma over whole blood recognized6. 1918 First use of human plasma (fresh) transfusion – Influenza Antitoxin7. 1930’s citrated plasma (fresh) routinely used for transfusion8. 1935 plasma used as a hemostatic agent for the first time9. WWII Frozen and Dried Plasma developed10.1932-41 Cryoprecipitate/Labile Factors Present in Plasma

FFP Use in Children

1. 1934 First Description FFP use in Child (sepsis)2. 1936-1963 Case Reports and Small Series3. 1964 First Randomized Controlled Trial4. 1968 First Large Neonatal Series

• 53 Subjects (13/40)with Heart Disease• Surgery with Extracorporeal Circulation• Randomized FFP or Standard Care• 250/500 mls FFP• No reduction in bleeding

• 286 Consecutive Low Birth Weight Neonates• Coagulation Status Assessed By The Thrombotest• 59 Died; 21 Had ICH• Thrombotest < 10% increased risk for Death/ICH• Plasma 10 ml/kg lower risk of death p=0.07• 10 ml/kg plasma “usually raises the thrombotestlevel to about 30%.”

Thrombotest: Designed to Monitor CoumadinDeveloped in late 1950s by OwrenBovine Plasma Deficient to II,VII,IX and XCan Use Capillary Specimen

Coagulation Factors

Normal Range 50-150 % or 50-150 u/dl (units per deciliter)

What is a unit ?

The amount of coagulation factor activity present in 1 ml of normal plasma

Normal factor IX activity = 1 u/ml X 100 ml/dl = 100 u/dl = 100%

Target factor activity for bleeding hemophilia patient is 40-50%

10 ml/kg FFP increase factor IX level by 10% - inadequate for hemostasis(need 40 ml/kg)

3,252,149 Admissions Overall

92,731 FFP Admissions

The Percent of FFP Admissions (2.85)Did Not Change Between 2002-2009 (p = 0.10)

54% Infants

34% CPB Code

Overall: Venous Thrombosis 10% Arterial Thrombosis 5%

Rate of Venous Thrombosis With FFP Admissions Increased Tenfold

• 12 y.o. male with O.M.• Developed Mastoiditis and Septicemia• Treated with Antimicrobials and Surgery• Supported with FFP• Developed Venous Sinus Thrombosis• Completely Recovered
