    Abstract:
    OBJECTIVE: Fresh whole blood (WB) has been used in military applications and cardiac surgery. We undertook a study of the coagulation properties of refrigerated WB stored for 21 days and compared them with the properties of reconstituted WB. STUDY DESIGN AND METHODS: Ten WB units were obtained from healthy volunteer donors and stored at 4 ± 2°C. Samples were obtained on Days 1, 2, 4, 6, 8, 10, 14 and 21 from the WB units. Ten units of reconstituted WB were prepared with a ratio of red cells, platelets and plasma of 1:1:1. Tests included complete blood count, electrolyte, routine coagulation, blood coagulation factor and thromboelastography. RESULTS: There was a progressive decline in Hb, WBC, PLT, sodium and coagulation factors but a progressive increase in APTT, PT and potassium in WB. The concentrations of factor (F)V and FVIII as well as FII and FX of WB were higher before Days 4, 2, 8 and 14, respectively, compared with the concentrations of reconstituted WB. The concentrations of FVII, FIX, FXI and FXII in WB were found to be equal to or higher than those in reconstituted WB throughout the course of 21 days. TEG variables in all WB units were normal throughout the course of 10 days. The mean PT and APTT of WB were lower than those of reconstituted WB before Days 14 and 10, respectively. CONCLUSION: This study suggests that the coagulation properties of refrigerated WB were equal to or superior to those of reconstituted WB for a minimum of 10 days.
