摘　　要：目的　探讨氧气湿化瓶导致医院感染的途径和预防措施。方法　采集10个氧气湿化瓶使用前、中、后各部位样品进行细菌培养检查,同时对湿化水、室内空气和医护人员的手进行细菌培养检测,并采集患者痰液进行培养检查。结果　10个氧气湿化瓶使用前各部位、室内空气和医护人员的手未检到患者感染细菌,患者使用后40%的氧气湿化瓶的内芯、内壁、出气口及管道检到与患者痰液培养结果相同的致病菌。结论　氧气湿化瓶易被患者污染,其内芯是导致医院感染的最危险因素,应对其各部位进行彻底消毒。OBJECTIVE To investigate the route of nosocomial infection induced by oxygen moisture bottles and preventive measures in ICU. METHODS Several parts of 10 oxygen moisture bottles, moistured water, ward air, and hands of doctors and nurses were detected by bacteriology methods, and the sputa of patients were cultured. RESULTS Before inhaling oxygen, the bacteria were not detected from every parts of 10 oxygen moisture bottles, ward air, and hands of doctors and nurses; after inhaling oxygen, the pathogens identified with isolates from the patients′ sputa were detected from 40% oxygen moisture bottles, including the inner core, inner wall, exit, and tube. CONCLUSIONS Oxygen moisture bottle is easily contaminated by patients. Its inner core is the most dangerous factor of nosocomial infection and its every parts must be thoroughly disinfected.
