Lancet haemat:输注储存35天以上的红细胞是否会影响患者院内死亡的风险?

输注储存35天以上的红细胞是否会给患者带来危害?尚没有这方面的随机试验。现研究人员对INFORM试验里的输注储存35天以上的红细胞的患者的院内死亡的风险进行评估。

输注储存35天以上的红细胞是否会给患者带来危害?尚没有这方面的随机试验。现研究人员对INFORM试验里的输注储存35天以上的红细胞的患者的院内死亡的风险进行评估。

研究人员对INFORM试验进行二次分析,该试验是在多个国家的6所医院进行的一个实用性的、多中心的、随机对照试验,受试者是年满18岁的需输注红细胞的患者。研究人员根据受试者在医院每天输注的任何血液单位的最长储存时间将其分成3组:≤7天、8-35天、>35天。主要评估项目是与输注储存≤7天的红细胞的患者相比,输注储存35天以上的红细胞的患者发生院内死亡的风险。

2012年4月2日-2015年10月21日,共招募31 497位受试者,24 736位被纳入本次分析。10位患者因信息缺失而排除。4480位(18%)患者暴露于最长储存时间的红细胞,1392位(6%)患者暴露于最短储存时间的红细胞,18854位(76%)患者暴露于储存8-35天的红细胞。中位随访时间11天(IQR6-20)。根据人口统计学变量、诊断类别和血液制品使用历史校正后,与输注新鲜血制品的人群相比,输注储存35天以上的红细胞的患者院内死亡的风险无明显改变(输注A或O型血的人群:危险比0.94,95% CI 0.73-1.20,p=0.60;所有人群:0.91,0.72-1.14,p=0.40)。输注储存8-35天的红细胞的患者和储存不多于7天的红细胞的患者之间院内死亡的风险无差别(0.92,0.74-1.15,p=0.48;0.90,0.73-1.10,p=0.29)。

输注储存35天以上的红细胞不会影响院内死亡率,表明现有的血液储存管理是合理的。
