全血室温保存8和24小时对所制备血液成分中细菌生长的影响

全血采集后在室温保存的最长时间从8小时延长到24小时,有多方面的益处。欲作上述变更,除需表明经室温保存24小时后的全血所制备的血液成分仍保持其功能外,还需证明延长室温保存时间不增加细菌的繁殖。为此,将2单位全血混合,接种细菌后再分成2个单位,分别室温保存8小时和24小时,然后分离血液成分;在血液成分的贮存过程中,检查其中所含细菌的水平。结果表明,对所试验的5种常见血液污染菌,全血在室温保存24小时并不增加这些细菌在血液成分贮存过程中的繁殖速率。

ENGLISH ABSTRACTS OF ORIGNAL ARTICLES Effect of whole Blood Storage at Room Temperature for 8 and 24 Hours on Bacterial Growth in Prepared Blood Components

The increase in the maximum time of collected whole blood storage at room temperature from 8 to 24 hours should bring about the versatile benefits. For making the mentioned above change it was necessary not only to demonstrate the blood components prepared from the whole blood stored at room temperature for 24 hours should still keep their functions, but also to indicate that the increase in the time of whole blood storage at room temperature couldn't accelerate the bacterial proliferation. Therefore, the two units of whole blood were pooled,inoculated with bacteria, split again into two units,stored at room temperature for 8 and 24 hours, respectively,and then the blood components were separated. The levels of the bacteria found in the blood components were measured in the process of their storage, indicating that the whole blood stored at room temperature for 24 hours couldn't accelerate the proliferation rate of 5 common contaminating bacteria existed in the blood components in their storage process.
