Abstract:
The objective of this study was to explore the possible effects of leukocyte elimination by filteration before storage on the quality of red blood cell concentrations (RCC) that prepared through two procedures. Eight units of red blood cell concentrations derived from whole blood after plasma separated (RCC1) and eight units of red blood cell concentrations derived from whole blood after platelet-rich plasma separated (RCC2) were divided randomly into filtered group and control group respectively. The RCC of filtered group were filtered by leukocyte deplete filter before storage. The control group didn't have any other treatments. These two groups were stored for five weeks at 4 degrees C according to AABB standard. Mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and plasma concentration of K(+) and lactate dehydrogenase (LDH), free hemoglobin (FHb), adenosine triphosphate (ATP) of red blood cell of all RCC were evaluated weekly, and bacteria contamination of all RCC was also detected after five weeks of storage. The results showed that there was no difference of MCV, MCH and MCHC and ATP level of red blood cell in all RCC of two groups, the ATP of red blood cell was lower than the control group on week 4 and 5. The average concentration of K(+) of the filtered group was less than the control group. The differences are significant except that of RCC1 stored till the third week. The plasma LDH concentration of filtered group was less than the control group, and the differences were exacerbate during the storing time prolonged. FHb release in the filtered group of RCC2 was significant less than that of control, but no significant difference was found between the two groups of RCC1. It was concluded that leukocyte elimination by filter before storage could be benefit to RCC preservation.
