滤除白细胞的血液成分质量与临床应用研究

目的探讨滤除白细胞(滤白)血液成分,尤其是悬浮少白细胞红细胞的品质及临床应用效果。方法随机收集全血91袋、滤白细胞全血90袋、悬浮红细胞(悬红)76袋和悬浮少白细胞红细胞(少白悬红)82袋(无缝接驳法34袋、连袋法48袋),检测并比较全血与滤白全血、2种方法制备的滤白全血、悬红与少白悬红的理化指标;随机收集4家医院近10年间的145名输注悬红与329名输注少白悬红(包括2种方法制备的少白悬红)患者的输血资料,对疗效做对比分析。结果滤白全血未见红细胞溶血现象,其血浆FHb和血液pH、K+、Na+较全血无明显变化分别为(0.19±0.10)g/L、6.88±0.06、(19.78±4.01)mmol/L和(141.62±8.10)mmol/L];无缝接驳法与连袋法制备的滤白全血的血浆FHb分别为(0.10±0.097)、(0.16±0.13)g/L(P>0.05);无缝接驳法、连袋法制备的少白悬红及悬红三者的容量和Hct比较:分别为(144.01±11.54)、(152.45±15.39)和(158.71±10.69)m l,0.48±0.03、0.50±0.03、0.53±0.05,差异具统计学意义(P<0.05);过滤法白细胞清除率高达3 log10,残余白细胞可低至10-6。内科、外科和非出血性等输血患者比较,输注少白悬红者与输注悬红者的输后RBC和Hb的中位数(M)分别为(0.55vs0.42)、(0.37vs0.28)、(0.62vs0.50)×1012/L和(14.5vs13.5)、(12vs8)、(18.43vs15.86)g/L。结论无缝接驳法与连袋滤器法制备的滤白全血和少白悬红品质稳定可靠,少白悬红细胞的输注效果好于悬红。

Detect and characterize platelet-reactive antibodies in patients who were refractory to platelet transfusions

Objective To investigate the quality and clinical effect of leucocyte-depleted blood components,especially leukocyte-depleted suspension RBC.Method The physicochemical indexes of the following specimen were determined: 91 bags of whole blood,90 bags of leukocyte-depleted whole blood,76 bags of suspension RBC,82 bags of leukocyte-depleted suspension RBC.The clinical data of 145 suspension RBC transfusion recipients and 329 leukocyte-depleted suspension RBC transfusion recipients was analyzed retrospectively....
