The Rh(D) negative patients received the transfusion of CSRBC or whole blood stored at -80 ℃ for 180 to 360 days. The changes in the indexes, such as blood TB, DB, K +, Na +, BUN, Cr, urine protein (URPO), UOB, Hb, HCT, serum total protein, relative to hemolytic reaction and blood volume before and after transfusion were observed. The results showed that after transfusion of CSRBC or whole blood 27 cases were negative for urine protein and UOB, and the levels of BUN and Cr were normal (P>0.05). Blood TB, DB, Hb, and HCT were increased, while pH, blood K + and blood Na + was normal with the difference being not significant before and after operation (P>0.05). Plasma protein was decreased, but there was no significant difference before and after operation (P>0.05). It was suggested that CSRBC or whole blood at -80 ℃ could be safely infused to the Rh(D) negative patients without side effects during the surgical operation.展开更多
目的：探讨直接抗人球蛋白试验（DAT）阳性患者的交叉配血方法。方法采用 DAT 法筛查红细胞表面的不规则抗体，微柱凝胶法进行血型鉴定，凝聚胺法和抗人球蛋白法交叉配血。结果共计5例 DAT 阳性的疑难配血患者，其血型分别为 A-DCcEe，O...目的：探讨直接抗人球蛋白试验（DAT）阳性患者的交叉配血方法。方法采用 DAT 法筛查红细胞表面的不规则抗体，微柱凝胶法进行血型鉴定，凝聚胺法和抗人球蛋白法交叉配血。结果共计5例 DAT 阳性的疑难配血患者，其血型分别为 A-DCcEe，O-DCCee，O-DCcee，A-DCCee 和 A-DCcee。选择相应血型抗原阴性的供者血样进行交叉配血，凝集强度均弱于自身对照，建议观察输注洗涤红细胞，患者未发生不良反应。结论对于 DAT 阳性的患者，可配合性输注相应血型抗原阴性的洗涤红细胞。展开更多
目的探究在冰冻红细胞解冻洗涤液中添加适宜浓度的木糖醇,提高解冻红细胞回收率的可行性。方法选择6 d内制备的400 ml去白细胞悬浮红细胞20袋,离心去浆后分装等量(100 ml)浓缩红细胞作为实验组和对照组,实验组在解冻第1次洗涤液(80 ml 9...目的探究在冰冻红细胞解冻洗涤液中添加适宜浓度的木糖醇,提高解冻红细胞回收率的可行性。方法选择6 d内制备的400 ml去白细胞悬浮红细胞20袋,离心去浆后分装等量(100 ml)浓缩红细胞作为实验组和对照组,实验组在解冻第1次洗涤液(80 ml 9%Na Cl)和第2次洗涤液(200 ml 0.9%Na Cl)中分别加入终浓度为1.2%、0.2%的木糖醇,比较两组的RBC回收率、红细胞渗透脆性、甘油残留量,同时测定冰冻红细胞解冻洗涤过程中各阶段的游离血红蛋白含量,明确提高解冻红细胞回收率的关键步骤。结果实验组RBC回收率显著高于对照组(t=-10.222,P<0.05),而红细胞渗透脆性、甘油残留量与对照组相比差异无统计学意义(P>0.05)。解冻第1次洗涤后血浆游离血红蛋白含量以实验组显著低于对照组(t=24.496,P<0.05),其余洗涤步骤的差异则无统计学意义(P>0.05)。结论冰冻红细胞经第1次洗涤液(80 ml 9%Na Cl)的解冻洗涤过程为RBC回收率提高的关键步骤。展开更多
