Definition:Definition:

• Blood products: any theraeutic

substance prepared from humanblood.

• Whole blood: Unseparated bloodcollected into an approved container

containing an anticoagulant-preservative solution.

2. Plasma or platelets collected by apheresis

3. Cryoprecipitate, prepared from freshfrozen plasma rich in FVIII and

fibrinogen.

Historical note:1665

The first recorded successful lood transfusion occurs in England

(dogs to dogs)

Richard Lower, performed the firstsuccessful animal transfusion in 1665,

when he transferred blood from the carotid

artery of one dog to the jugular vein ofanother.

Historical Note:1667Historical Note:1667

• In November 1667, Lower

transfused Mr. Arthur Coga, "amildly melancholy insane man,"with the blood of a lamb. Mr.Coga, described his experience to

the Royal Society of Medicine andstated that he was much better."cracked a little in his head.“

• Denis’ fourth attempt endedfatally, he was charged withmurder

Historical Note

• For the next 150 years, there was littleinterest in transfusion.

Historical Note:1818

•• JAMES BLUNDELL 1818JAMES BLUNDELL 1818

– interest in transfusionwas revived by James

Blundell in 1818, it wason the basis of replacement of lostblood in puerperal

hemorrhage and afterseries of experiments.

Historical Note:1818

• Blundell failed in hisfirst four desperate

attempts to savewomen on the pointof death frompostpartal

hemorrhage, but

• he succeeded in fiveof the next six

attempts…….

• Patient’sselection……early

stage of PPH.

1. To maintain viability & function of relevant constituent.2. To prevent physical changes detrimental to constituent.3. Minimize bacterial proliferation.

Blood is collected as whole blood.

Blood destined for component preparation is drawn into bags with integrallyattached transfer container (closed system)

FFP Packed RBCplatelets

a single donation of whole blood has supplied three separate components(packed red blood cells, platelets, fresh frozen plasma) that can potentially

benefit three different patients.

CRYOPRECIPITATE:

Melt FFP between 1-6oC Cold insoluble portion of plasma remaining is called cryoprecipitate

Platelet collection using

apheresis system yield

higher concentration of

platelets.
