保存人红细胞的新策略一抗氧化剂保养液保存效果的研究

塑料血袋盛义务献血员的静脉血（含适量保养液）并置4℃冰箱保存。在保存前、后不同时间检查各项指标,旨在研究抗氧化剂保养液延长人血红细胞在4℃条件下的保存时间,以缓解血液保存供应的压力,为输血抢救创造有利条件。实验分3组：ACD组,GMA组和抗氧化剂（SOD）组）。研究结果表明,在4℃条件下保存75天后SOD组红细胞血红蛋白回收率为87．2％,血浆血红蛋白（mg/L)为193．2,P50（mmHg)为34．0（正常值为33．1）,最大变形指数（DImax）为0．2413,即为正常值的74．3％,外观检查无明显溶血、变色、气泡和凝块。结论提示,用抗氧化剂保养液保存红细胞在4℃条件下可延长75天,其红细胞血红蛋白和血浆血红蛋白回收率附合国家《血站基本标准》规定要求。

New tactics of human red blood cells stored at 4 degrees C-protective effect of antioxidant solution on red blood cells damage]

Aliquots of venous blood from healthy donor were collected in plastic blood storage bags with ACD, GMA or antioxidant solution (superoxide dismutase, SOD), respectively, and stored at 4 degrees C. After storage for varying periods, the parameters of the blood were detected in the blood samples. Results showed that the parameters of the blood stored at 4 degrees C for 75 days in SOD group were following: the recovery of RBC-Hb was 87.2%, plasma-Hb (mg/L) was 193.2, P50 (mmHg) was 34.0 (normal value was 33.1); deformability (DImax) was 0.2413 (74.3% of normal value). There was no evident hemolysis, color change, air bubble and clots. It was concluded that human RBC stored at 4 degrees C for 75 days with SOD solution, recovery of levels of RBC-Hb and plasma-Hb were accorded with the requirements of "Basic Demands of Blood Station" in China.
