为探讨改良环境清洁消毒方案在重症监护室的消毒效果,在传统的环境物体表面清洁消毒方案的基础上,通过延长每次清洁消毒时间、增加每天清洁消毒次数来改良环境清洁消毒方案,采用改良方案与传统方案分别对各20名患者周围环境中12种物体表面进行清洁消毒,计算两种方案清洁消毒前后6个时间点各种物体表面的菌落数,并进行比较。在实施两种清洁消毒方案1~6 d后分别统计患者医院感染的发生率。经Repeated Measures和Multivariate过程进行重复测量方差分析和多元方差分析,两种清洁消毒方案的时间、时间×清洁消毒方案的P值均<0.05,提示时间因素以及时间因素和分组的交互作用有统计学意义。用改良方案清洁消毒4.5 h和8.5 h后,83.3%物体表面的菌落数明显低于传统方案组(P<0.05),用改良方案清洁消毒12.5~16.5 h后,所有物体表面的菌落数两组间均明显低于传统方案组(P<0.05)。在改良方案清洁消毒后3~6 d时,患者医院感染率明显低于传统方案组(P<0.05)。说明改良方案清洁消毒效果更为显著,并可能更有助于控制重症监护室医院感染的发生。
In order to explore the disinfection effect of the improved environment cleaning and disinfection program in the intensive care unit, on the basis of the traditional cleaning and disinfection program of environmental objects, the environment cleaning and disinfection program was improved by prolonging the time of cleaning and disinfection and increasing the number of cleaning and disinfection every day. Solutions and Traditional Solutions The surface of 12 objects in each of 20 patients were cleaned and disinfected respectively. The number of colonies on various objects before and after cleaning and disinfection were calculated and compared. In the implementation of two kinds of cleaning and disinfection programs 1 ~ 6 d after the statistics of the incidence of nosocomial infections. Repeated measures of variance and multivariate analysis of variance were performed by Repeated Measures and Multivariate analysis. The time and time of two cleaning and disinfection programs and the P value of cleaning and disinfection programs were all less than 0.05, which indicated that the time factor and the interaction of time factor and grouping were statistically significant significance. After cleaning and disinfecting 4.5 h and 8.5 h with the improved scheme, the number of colonies on the surface of 83.3% was significantly lower than that of the traditional scheme (P <0.05). After cleaning and disinfecting for 12.5-16.5 h with the improved scheme, the number of colonies on all the objects was two groups Were significantly lower than the traditional program group (P <0.05). In the improved program 3 ~ 6 d after cleaning and disinfection, the hospital infection rate was significantly lower than the traditional program group (P <0.05). Indicating that the improved program cleansing and disinfecting effect is more significant, and may be more helpful to control the incidence of nosocomial infections in intensive care unit.
