床单元消毒法预防医院感染的效果评价

Effect of bed-unit area disinfection on prevention of nosocomial infections

目的探讨医院ICU疑似或发生耐药鲍氏不动杆菌暴发流行时应用床单元区域消毒法进行消毒的效果。方法疑似泛耐药鲍氏不动杆菌暴发流行时,立即对ICU常态环境下进行第1次采样检测目标菌;腾空病房按常规方法终末消毒后进行第2次采样检测;改进方法采用床单元区域消毒法重新消毒,并第3次采样检测目标菌。结果 ICU环境鲍氏不动杆菌第1次常态下总检出率45.5%,其中床单元组70.0%;第2次常规方法终末消毒后总检出率25.0%,床单元组62.5%;第3次采取床单元区域消毒法消毒后检出率0。结论采取床单元区域消毒法可使环境消毒更为彻底有效,在疑似或发生鲍氏不动杆菌医院感染暴发时,对切断传播途径有着积极的意义,是加强干预措施的重要组成部分。

OBJECTIVE To explore the effect of bed-unit disinfection on prevention of suspected or confirmed Acinetobacter baumannii infections.METHODS When the suspected pandrug-resistant A.baumannii outbroke,the first sampling was conducted under the normal environment of ICU to detect the targeted bacteria;then the second sampling was carried out in the vacated ward after terminal disinfection with routine method,the bed-unit area disinfection method was employed for re-disinfection,and the third sampling was performed to detect the targeted bacteria.RESULTS The overall detection rate of A.baumannii was 45.5% in the first sampling under the normal environment of ICU,the bed-unit area disinfection group 70.0%;the total detection rate was 25.0%after the terminal disinfection with routine method,the bed-unit area disinfection group 62.5%;the detection rate was 0in the third sampling after the application of bed-unit area disinfection method.CONCLUSIONThe bed-unit area disinfection method can achieve more thorough effect on environmental disinfection;it is of positive significance in cutting off the transmission routes as the suspected or confirmed A.baumannii infection prevails,playing as a part of intervention measures.
