目的考察滤除白细胞对全血保存质量和功能的影响。方法 1袋(2 U=400 mL)新鲜全血均分为滤除白细胞全血(简称滤白)组:按照去白滤器的使用说明书操作,在采血<6 h过滤制备去白细胞全血;对照组:不滤除白细胞。过滤及未过滤的全血均采用...目的考察滤除白细胞对全血保存质量和功能的影响。方法 1袋(2 U=400 mL)新鲜全血均分为滤除白细胞全血(简称滤白)组:按照去白滤器的使用说明书操作,在采血<6 h过滤制备去白细胞全血;对照组:不滤除白细胞。过滤及未过滤的全血均采用无菌方式分别分为6小袋[(30～40)mL/袋],(4±2)℃常规保存,分别于保存1、7、14、21、28、35 d各取1小袋,检测血常规、pH、游离血红蛋白(FHb)、氧亲和力(P50)、ATP、2,3-二磷酸甘油酸(2,3-DPG)、电解质、红细胞膜表面PS、CD47表达、葡萄糖、乳酸等指标,比较过滤与未过滤全血质量的差异。结果实验组1 U全血过滤后剩余白细胞数为(0.32±0.05)×106个;滤白组和对照组比较,保存35 d时血红蛋白(Hb)(g/L)为149.00±11.53 vs 137.20±3.96、MCV(fL)为98.90±3.23 vs 98.96±2.10、pH为6.78±0.02 vs6.75±0.02、P50(mmHg)为15.36±0.63 vs 15.18±0.22、ATP(μmol/gHb)为3.57±0.15 vs 3.61±1.02、2,3-DPG(mmol/L)为0.13±0.09 vs 0.22±0.2、PS阳性率(%)为0.96±0.08 vs 1.19±0.03、CD47阳性率(%)为47.65±3.92 vs 48.37±4.35(P>0.05),溶血率(%)为0.08±0.02 vs 0.12±0.03(P<0.05);保存28 d时乳酸(mmol/L)为15.76±0.19 vs 18.73±0.97、葡萄糖(mmol/L)为20.21±0.55 vs 18.57±0.46(P<0.05)。结论全血离体保存期间会发生一系列质量和功能的变化,滤除白细胞全血的溶血率、乳酸、葡萄糖等指标略优于未过滤的全血,二者的携释氧功能及其他生理生化指标均无明显差异,说明滤除白细胞未对全血保存期间的质量产生不良影响,并可能有利于血液保存。展开更多
