细菌污染血液成分是导致输血感染和死亡的主要原因,为明确血小板浆的污染情况,作者对5617份血小板浆输用前后及储存4～5天后,进行细胞培养和革兰氏染色,以综合评价血小板浆有无细菌污染及细菌污染程度。这5617份血小板浆中,有3141份为混合血小板浆。单供者血小板浆输血前后均无细菌污染,而随机献血的混和血小板浆有6例发生细菌污染。在检查1437例输用随机献血的混合血小板浆中。发现了输血前无细菌污染而输血后出现细菌感染的情况。对6例细菌污染的输血袋进行细
Bacterial contamination of blood components is the leading cause of blood transfusion infection and death. To clarify the contamination of platelet pulp, the authors performed cell culture and Gram stain before, after, and for 4 to 5 days after transfusion of 567 platelets, Whether there is bacterial contamination of bacterial platelets and bacterial contamination levels. Of the 5,617 platelettes, 3141 were mixed platelets. Single donor platelet plasma before and after transfusion without bacterial contamination, and randomly donated mixed platelet plasma in 6 cases of bacterial contamination. A total of 1437 patients randomized to mixed blood platelets were randomized. No bacterial contamination was found before transfusion and bacterial infection was found after blood transfusion. 6 cases of bacterial contamination of the blood transfusion bag fine
