Abstract: The orientation rate of flowing erythrocytes was studied by electron spin resonance spectroscopy as a function of time on blood samples stored either in the classical anticoagulant solution CPD or in the new SAG resuspension medium. The maximum orientation rate decreases quickly and the critical shear rate increases strongly in CPD. These parameters are much more stable in SAG. These results indicate that the red blood cell deformability and rheological properties are well better preserved with the SAG storage procedure.
