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

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°Ｃ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°Ｃ条件下ＣＰＤＡ全血保存有效期为５ｄ。

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.
