28°C对血液保存质量影响的研究

Effects of air temperature 28°C on the quality of blood preservation

摘要: 目的：本文作者进行异常温度条件下血液保存的研究，其中对28℃条件下CPDA保存血的质量作了观察。方法：分别在0d、1d、2d、3d、4d、5d、6d和7d对ATP、游离血红蛋白（FHB）、葡萄糖（GLU）和pH进行测定。结果：ATP开始升高，而后下降；FHB持续升高，5d时明显升高；GLU和pH持续下降，开始较快，后明显减慢。几个指标都在5d时发生明显变化，其中红细胞ATP降至1.5μmol/gHb达到红细胞存活要求的最低水平。结论：我们的研究结果显示，28℃条件下CPDA全血保存有效期为5d。

Abstract: Objective: While studying blood transfusion at normal temperature, we observed CPDA blood quality at 28°C.Methods: The values of ATP, FHB, GLU and pH were measured after d1.2.3.4.5.6 and 7 preservation.Results: The results showed that ATP increased at the early time and then decreased rapidly; FHB increased progressively and GLU and PH gradually decreased. All of the above indicators changed significantly after 5 days. Among them, ATP decreased to 1.5 μmol/gHb,the minimum acceptable ATP level for 70% post-transfusion survival rate of red cells stored in CPDA preservatives. Conclusion: The limit preservation time of CPDA blood at 28°C is about 5 days.
