Abstract:
BACKGROUDNS: In Korea, CPDA-1 solution is currently used for blood preservation and by this anticoagulant solution, RBCs can be preserved for up to 35 days at the refrigerate temperature. RBC additive solutions (AS-1, AS-3, AS-5, SAG-M, SAG-PM) are widely used in the other countries for longer preservation of RBCs (42 days). We studied the survival of transfused RBCs preserved in SAG-M additive solution. MATERIALS AND METHODS: 400 mL of whole blood were collected from 8 healthy volunteers, Plasma was removed by centrifugation separation method at 2,960g, 10 minute and replaced by 100 mL of SAG-M additive solution. Autologous transfusions were done in two groups on day 20 and 42 with Na51CrO4 (Dupont, USA) labelled RBCs. After 3, 10, 15, 20, 30 minutes and 1, 2, 24 hours, 20 days, the venous blood samples were collected from the volunteers, and their radioactivities were measured by the Gamma-counter (Cobra II, Germany), and 24 hour survival rate were calculated by Moroff's method. RESULTS: The mean 24 hour survival rate was 89.0% in 20 days preservation group and 71.8% in 42 days preservation group. The mean half life of transfused RBCs were 27.8 days (n=2)and 24.3 days (n=4) in 20 days and 42 days preservation group, respectively. No complications were observed during the study period. CONCLUSIONS: The RBCs preserved in SAG-M additive solution were near within allowable survival rates for transfusion.
