BLOOD COMPONENTS:
OXYGEN-CARRYING PRODUCTS
THE WHOLE BLOOD AND ITS COMPONENTS:
WHOLE BLOOD
- ___
- ___ - ___
- mother / primary component
- unmodified - directly from the donor
WHOLE BLOOD
Indications:
Indications:
Active bleeding
Hemorrhagic shock
Exchange Transfusion
Both oxygen-carrying capacity and volume expansion required
WHOLE BLOOD
Shelf-life:
21 DAYS:
35 DAYS:
42 DAYS:
WHOLE BLOOD
Shelf-life:
21 DAYS: CPD, ACD, CP2D

21 DAYS: CPD, ACD, CP2D
35 DAYS: CPD-A1
42 DAYS: CPD-AS-1 (Adsol), AS/3 (Nutricel), AS-5 (Optisol)
WHOLE BLOOD
Characteristics:
* WBCs and Platelets - no longer viable after ____
* LABILE FACTORS (FACTORS ___ & ___) - significant ___ AFTER ___
- 24 HOURS
- V & VIII, decrease, 2 DAYS
WHOLE BLOOD
Storage Temp:
1-6 degC (monitored temp)
WHOLE BLOOD
Transport:
WET ICE w/ cloth & paper; do not put directly in ice
WHOLE BLOOD
Immediate Effect of one unit:
Post-transfusion CBC:
ABOUT 30% INCREASE Hct PER 1 UNIT WB
AFTER 6 HOURS
ASSOCIATED PROBLEMS AFTER WB TRANSFUSION
- Circulatory overload in patients that require only oxygen-carrying capacities in the RBC
PRBC - anemia or oxygen-carrying capacity
WB - both oxygen-carrying capacity and volume expansion; only if there is a shortage of component - Not indicated to correct anemia for normal volemic patients - the additional volume of plasma is unnecessary and may cause volume-related complications
CONTENTS:
PRBC -
LEUKODEPLETED RBCs -
WASHED RBCs -
CONTENTS:
PRBC - Hct should be 80% or less
LEUKODEPLETED RBCs - Residual WBCs
WASHED RBCs - Removal of plasma proteins, platelets, leukocytes and cellular debris

PRBC
Open System: Transfused within 24 hours; can be stored in refrigerator depending on the anticoagulant
Increased probability of product contamination; no integrally attached collection needles in the satellite bag
Closed System: Should NOT be exposed to air
If no PRBC → centrifuge WB to separate plasma and keep PRBC
LEUKODEPLETED RBCs
Closed System: depend on anticoagulant; same with other RBC components
Open System: 24 hours
REJUVENATED RBCs
Can be prepared 3 days after expiration of blood
Use of anticoagulant → New shelf life of rejuvenated RBC after addition of rejuvesol will be 24 HOURS
WASHED RBCs
Open System: valid for 24 hours
FROZEN > THAWED > DEGLYCEROLIZED RBCs
Frozen: 10 years
Deglycerolized: already gone thawing process; 24 hours
