NEJM:危重病患者应该输注新鲜红细胞还是陈旧红细胞?

2017-12-03 杨中华 脑血管病及重症文献导读

红细胞输注在危重病人中很常见,红细胞贮存时间一般为42天。贮存期间,红细胞经历结构、生化和代谢的变化,称为“贮存损害”,这可能是有害的。然而,在实际临床实践中血库往往把贮存时间最长的陈旧红细胞提供给患者。


红细胞输注在危重病人中很常见,红细胞贮存时间一般为42天。贮存期间,红细胞经历结构、生化和代谢的变化,称为“贮存损害”,这可能是有害的。然而,在实际临床实践中血库往往把贮存时间最长的陈旧红细胞提供给患者。

有研究发现输注陈旧红细胞可能会增加危重病患者、外科患者以及创伤患者的死亡率。与其他疾病相比,危重病可能对贮存红细胞不良作用更加敏感。ABLE试验纳入了2430例高死亡风险的危重病成人患者,INFORM试验纳入了10578例入住ICU的患者。这两个试验显示输注新鲜红细胞和陈旧红细胞对预后没有影响。ABLE试验中,随机到首次输血的时间间隔为10h,这将影响输血的效果,降低了组间的差异。在INFORM试验中,死亡率较低,提示这些患者病情较轻。此外,最近一项纳入了这两项试验的meta分析也没有排除输注新鲜红细胞的害处。

2017年11月来自澳大利亚的D. James Cooper等在NEJM上公布了TRANSFUSE试验结果,目的在于比较危重病成人患者输注新鲜和陈旧红细胞的差异。

该研究为国际多中心随机双盲临床试验。纳入的患者随机给予最新鲜的相容同种异体红细胞(compatible, allogeneic red cells)(短期贮存组)或最陈旧的相容同种异体红细胞(长期贮存组)。主要终点为90天死亡率。

五个国家59家中心共随机了4994例患者,其中4919例纳入主要分析。短期贮存组2457例,平均贮存期为11.8天;长期贮存组2462例,平均贮存期未22.4天。90天时,短期贮存组和长期贮存组的死亡率分别为24.8%和24.1%((absolute risk difference, 0.7 %; 95% CI, ?1.7 - 3.1; P = 0.57)。180天时,绝对风险差异为0.4%(95% CI,-2.1 - 3.0;P = 0.75)。大部分预先设定的二级终点两组都没有显著性差异。

最终作者认为输注新鲜和陈旧红细胞不会影响危重病患者90天死亡率。
