CAM201 Transfusion and blood products Flashcards
What are the Indications for Blood Transfusions?
Only if the expected benefit will outweigh the potential risks
The decision to transfuse RBCs, for instance, depends on clinical judgement for the individual patient’s circumstance. Also depends on reactions to possible previous transfusion, and rare ABs present, etc.
Guidelines for RBC Transfusion based on Hb:
Hb >100mg/L - transfusion is unlikely to be appropriate
Hb 70-100mg/l - may be appropriate, especially if blood loss involved. If no other serious issues are present, treatment with iron may be appropriate to raise Hb levels (unless patient hypoxic, etc)
Hb s medical record
Record andy adverse effects
What are the types of transfusion products?
PC - Packed Cells (RBCs)
Platelets
FFP - Fresh Frozen Plasma
Cryoprecipitate
What is PC (Packed Cells) and what are indications?
PC = Packed RBCs without plasma
Used when patient required RBCs for O2 carrying (e.g. massive blood loss)
Must be ABO compatible
What is ‘Platelets’ what are indication?
Just platelets.
Used if decreased Plt count, or if platelets are abnormal
E.g. bone marrow disease
*May contain RBCs so use ABO compatible
What is ‘FFP’ and what are indications?
FFP = Fresh Frozen Plasma.
Contains plasma fluid, without blood cells
Contains all soluble coagulation factors
Used if need to replace coagulation factors
E.g. in liver disease, in massive transfusion where factors will need to be replaced, in DIC, to reverse Heparin/Warfarin overdose
What is Cryoprecipitate?
Cryoprecipitate contains concentrated FVIII, VWF, FXIII and FI (fibrinogen)
Used when these factors need to be replaced, e.g. liver disease, DIC, massive transfusion.
Can be used to treat FVIII deficiency (Haemophilia A) or VWF deficiency if no better alternative
