Studies were conducted to examine whether an experimental additive solution (EAS-2) containing, in mM: 20 NH4Cl, 30 Na2HPO4, 2 adenine, 110 dextrose, 55 mannitol, pH 7.15, would be useful to extend the storage shelf life of human RBCs. With 6 pairs of split units, ATP concentrations were better maintained for 12 weeks with EAS-2 than with Adsol (1.8 vs. 1.1 mumol/g Hb, respectively, p = 0.002). Autologous 24-hours 51Cr viability values for split units in the same donors were: on 6 paired units at 8 weeks, EAS-2 87.0 +/- 4.5%, Adsol 72.6 +/- 2.3%, p = 0.004; on 11 paired units at 9 weeks, EAS-2 79.5 +/- 7.1%, Adsol 68.2 +/- 10.1%, p = 0.0003. The data suggest that packed RBCs stored for 9 weeks with EAS-2 will be suitable for transfusion following the removal of supernatant with a single washing step.
开展了多项研究,以检验一种实验性添加剂溶液(EAS-2)是否有助于延长人红细胞的储存保质期,该溶液含有(以毫摩尔计):20氯化铵、30磷酸氢二钠、2腺嘌呤、110葡萄糖、55甘露醇,pH值为7.15。使用6对分离单位进行研究,结果显示,与Adsol相比,使用EAS-2可使ATP浓度在12周内得到更好的维持(分别为1.8与1.1微摩尔/克血红蛋白,p = 0.002)。同一供体的分离单位的自体24小时51铬活力值如下:在8周时对6对单位进行检测,EAS-2为87.0 +/- 4.5%,Adsol为72.6 +/- 2.3%,p = 0.004;在9周时对11对单位进行检测,EAS-2为79.5 +/- 7.1%,Adsol为68.2 +/- 10.1%,p = 0.0003。数据表明,使用EAS-2储存9周的浓缩红细胞,在经过单步洗涤去除上清液后将适合用于输血。
