目的 分析多功能空气消毒机在普通内科病房的动态消毒效果，为病房空气质量的控制提供参考依据。 方法 2010年9月－2011年4月对普通内科病房在动态状态下进行细菌检测并使用多功能空气消毒机消毒，并就消毒前后的空气细菌菌落总数进行分析比较。 结果 在动态状态下，病房关门关窗并开启空调机时，使用多功能空气消毒机消毒前的空气细菌菌落总数显著高于消毒后，差异有统计学意义（P＜0.05）；病房在开门开窗时，使用多功能空气消毒机消毒前后的空气细菌菌落总数比较，差异无统计学意义（P＞0.05）。 结论 普通内科病房在关门关窗并开启空调机动态状态下，使用多功能空气消毒机可以降低空气细菌菌落总数，改善房间空气质量。
In recent years, pathogenic metagenomic next-generation sequencing (mNGS) technology has become more and more widely used in the field of clinical infection. Driven by clinical needs, mNGS technology is constantly being optimized and developed. From manual operation to automated process, from simple qualitative detection to quantitative monitoring, from infection identification to multi-dimensional diagnosis of “infection+tumor”, certain research results have been achieved. Of course, there are still some limitations in clinical application of this technology. For example, there are many mNGS detection related reagents in China, but a systematic and complete quality management control and evaluation system has not been established. Further research is needed. This article summarizes the development and application of pathogen metagenomic sequencing technology in recent years, as well as the standardization and normalized process of mNGS detection, in order to provide a reference for pathogen mNGS sequencing to better assist clinical infection diagnosis.
