[目的]通过规范空气层流洁净病房内人员流动与物质流动,探讨洁净ICU区域人物流管理对医院内感染发生率的影响。[方法]制定ICU人物流进出的相关制度并严格执行,每月两次不定期对洁净ICU病区进行空气培养,与采取传统模式管理的专科ICU病区的空气培养进行对比分析。[结果]2009～2010年对洁净ICU及普通ICU各进行48次的空气培养,每月2次,洁净ICU细菌超标1次,合格率97.9%;普通ICU细菌超标7次,合格率85.4%两组的合格率相比差异有统计学意义(χ2=5.79,P﹤0.05)。[结论]规范的人员流动与物质流动管理能有效降低层流洁净环境的空气污染程度,控制或降低医院内感染发生。
[Objective] To discuss the influence of logistics management in clean ICU area on the incidence of nosocomial infection by regulating the flow of people and material flow in the clean room of air laminar flow. [Method] The system of ICU logistics entering and exiting was established and implemented strictly. The air of the intensive ICU ward was air-conditioned from time to time twice a month, and compared with the air culture of specialist ICU ward adopting traditional model management. [Result] The air samples were collected from clean ICU and ordinary ICU 48 times every year from 2009 to 2010, twice a month. The bacteria in the clean ICU exceeded the standard by 1 time with the pass rate of 97.9%. The bacteria in the common ICU exceeded the standard by 7 times and the pass rate was 85.4% The qualified rate of the group was statistically significant (χ2 = 5.79, P <0.05). [Conclusion] The standardized management of staff turnover and material flow can effectively reduce the air pollution in laminar flow clean environment and control or reduce the occurrence of nosocomial infection.
