【摘要】：目的评价键盘保护膜对降低ICU键盘微生物污染的效果,以预防医院感染。方法 2014年2-4月某医院两个ICU的109个键盘配备键盘保护膜为研究对象,根据对键盘保护膜的清洗消毒方式分为两组,外科重症监护病房(SICU)50个键盘保护膜采用有效氯消毒液进行擦拭,外科重症监护病房A(SICU-A)59个键盘保护膜用流动水冲洗,对清洗前后的键盘及键盘保护膜进行采样,监测和计算污染菌落数。结果两组ICU采集键盘样本,清洗干预前后键盘菌落均数分别为349.3CFU/10键、226.2CFU/10键,两者比较差异有统计学意义(P0.05);SICU-A清洗后的菌落均数173.5CFU/10键,远低于清洗前的458.6CFU/10键(P=0.01),SICU擦拭前后的菌落数差异无统计学意义。结论键盘保护膜可降低电脑键盘的微生物污染程度,对键盘保护膜的清洗消毒,水洗比擦拭更有效。
[Abstract]:Objective To evaluate the effect of the keyboard protective film on the reduction of the microbial contamination of the keyboard of the ICU in order to prevent the infection of the hospital. Methods From February to April,2014,109 keyboards in two ICU of a hospital were equipped with a keyboard protective film as the research object. The cleaning and disinfection methods of the keyboard protective film were divided into two groups. The 50 keyboard protective films of the surgical intensive care unit (SICU) were wiped with effective chlorine disinfectant. The 59 keyboard protective films of the surgical intensive care unit A (SICU-A) were rinsed with flowing water, and the keyboard and the keyboard protective film before and after cleaning were sampled, and the number of contaminating colonies was monitored and calculated. Results The number of microcolonies in the two groups was 349.3 CFU/10 and 226.2 CFU/10, respectively. The average number of colonies after cleaning was 173.5 CFU/10, which was much lower than that of the 458.6 CFU/10 (P = 0.01) before cleaning. There was no statistical difference in the number of colonies before and after exposure to the SICU. Conclusion The keyboard protective film can reduce the microbial contamination level of the computer keyboard, and can be used to clean and disinfect the protective film of the keyboard, and the water washing is more effective than the wiping.
