摘　　要：目的加强病房氧气吸入治疗器具的消毒监测管理,避免医院获得性呼吸道感染。方法对医院32个临床科室正在使用的氧气湿化瓶及湿化液进行采样,检测细菌菌落数及菌种,将氧疗器具依使用方式不同分为两组,即长期给氧组及间断给氧组,分析氧疗装置的细菌污染情况与氧疗方式的关系。结果共采样748份,其中长期给氧组386份,合格率为90.67%,间断给氧组362份,合格率为61.88%;病原菌以革兰阴性菌为主,凝固酶阴性葡萄球菌、大肠埃希菌及类产碱假单胞菌较多。结论重视病房氧气吸入治疗器具的规范化管理,加强氧气吸入治疗器具的消毒监测,对预防控制医院获得性呼吸道感染至关重要。OBJECTIVE To strengthen the monitoring of disinfection of ward oxygen inhalation therapy apparatus so as to avoid the hospital-acquired respiratory tract infections.METHODS The sampling of the oxygen humidifier bottles and wet fluid were performed in 32 clinical departments,the bacterial colony counts and the species were detected,the oxygen therapy apparatuses were divided into two groups according to approaches,the long-term oxygen therapy group and the intermittent oxygen therapy group,the correlation between the bacterial contamination of oxygen therapy devices and oxygen therapy approach was analyzed.RESULTS There were totally 748 samples including 386 samples with long-term oxygen therapy with the qualified rate of 90.67% and 362 samples of intermittent oxygen therapy with the qualified rate of 61.88%;gram-negative bacteria were the predominant pathogens,followed by the coagulase-negative Staphylococci,Escherichia coli and Pseudomonas alcaligenes.CONCLUSION It is of great significance to focus on the standardized management of oxygen inhalation therapy apparatus and strengthen the monitoring of disinfection of oxygen inhalation therapy apparatus.
