红细胞制剂血辫质量的监测分析

Monitoring and analysis of red blood cell braided samples quality

目的:通过红细胞制剂血辫质量的调查分析,探讨血辫质量对临床用血安全的重要性。方法:统计分析血站供应红细胞制剂10902 U共计6953份血辫的长度、抗凝情况、溶血情况及对输血前相容性检测试验的影响,判断血辫质量。结果:6953份血辫总长度均符合要求,其中分段<5 cm占1.47%(102/6953);不抗凝血辫占5.55%(386/6953);保存第30天血辫溶血率为6.70%(466/6953)。结论:抗凝良好、足够长度的血辫能反映血袋中血液的免疫性状态,满足输血前相容性检测试验要求,确保临床输血安全。

Objective To explore the importance of blood braid quality for clinical blood safety by investigating and analyzing the quality of red blood cell braided samples.Methods The quality of 6953 blood braided samples from 10902 U red blood cell preparation was judged by analyzing and comparing the length,anticoagulation and hemolysis.Results The total length of blood braids in 6953 cases met the requirements,and the proportion of subsections length<5 cm was 1.47%(102/6953).The proportion of non-anticoagulant was 5.55%(386/6593).The hemolysis rate was 6.70%(466/6593)after 30 days of storage.Conclusion Adequate length of blood braids and good anticoagulation can reflect the immune status of blood in blood bags,meet the requirements of compatibility test before transfusion,can ensure the safety of clinical blood transfusion.
