保存前去除白细胞对浓缩红细胞保存质量影响研究

为了研究保存前去除白细胞对不同方法制备的浓缩红细胞 (RCC)保存质量的可能影响 ,分别取分离血浆后所得浓缩红细胞 (RCC1)和分离富含血小板血浆后所得含少量血浆的浓缩红细胞 (RCC2 )各 8袋 ,每袋等量分为两份 :过滤组和对照组。过滤组在保存当天用去白细胞滤器过滤 ,然后按常规方法 4℃保存 35天 ;对照组直接 4℃常规保存 5周。每周取样本测定平均红细胞体积 (MCV)、平均红细胞血红蛋白含量 (MCH)和平均红细胞血红蛋白浓度 (MCHC) ,血浆K+浓度和乳酸脱氢酶 (LDH) ,游离血红蛋白 (FHb)和红细胞ATP水平 ,同时做细菌培养污染监测。结果表明 :两种方法制备的RCC在过滤组与对照组中MCV ,MCH和MCHC无显著差别 ;红细胞ATP水平在保存第 0 ,1,2和 3周过滤组与对照组无显著差异 ,第 4和 5周过滤组红细胞ATP水平低于对照组 (P <0 .0 5 ) ;在保存过程中过滤组K+水平低于对照组 ,除了RCC1在保存第 0 ,1,2和 3周与对照组无显著差别外 ,均有显著差异 (P <0 .0 5 )。过滤组血浆LDH释放量显著低于对照组 (P <0 .0 1) ,在分离血小板后制备的RCC2这种差别更为明显。在保存期间RCC2组血浆的FHb水平过滤组显著低于对照组 (P <0 .0 5 ) ,而RCC1两组间FHb水平无显著差异。各组细菌培养均为无细菌生长。结论 :保存前去白细胞过

Effects of Leukocyte Elimination before Storage on Quality of Red Blood Cell Concentration

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.
