AF-A低噪音阻菌式输氧器和传统氧气湿化瓶使用分析

目的 探讨传统的氧气湿化瓶导致医院感染的途径,选择安全、有效控制医源性感染的吸氧设施. 方法 分别对51例呼吸道感染患者痰液、37例使用传统氧气湿化瓶吸氧的湿化瓶、98例使用一次性AF-A低噪音阻菌式输氧器,使用1～6 d后进行细菌培养. 结果 51例医院感染患者中使用传统氧气湿化瓶的细菌培养与患者痰液培养的病原菌结果有明显的一致性,痰培养检测到铜绿假单胞菌、肺炎克雷伯菌、大肠埃希菌、鲍氏不动杆菌,分别占21.43%、21.43%、10.71%、3.57%;湿化瓶检测到铜绿假单胞菌、肺炎克雷伯菌、大肠埃希菌、鲍氏不动杆菌,分别占34.78%、21.74%、8.69%、13.05%,而AF-A低噪音阻菌式输氧器使用4 d内无细菌生长,安全使用期为5 d. 结论 传统氧气湿化瓶易被细菌污染,是导致医源性呼吸系统感染的危险因素,而使用一次性AF-A低噪音阻菌式输氧器可防止因氧气湿化瓶污染引起的医院感染.

Analysis and Discussion of AF-A Low-noise Bacteria-resistant Oxygen Device and Traditional Oxygen-humidified Bottles

OBJECTIVE To explore the methods of the traditional bottle of oxygen-humidified bottles leading to the nosocomial infection,and to choose a safe and effective oxygen facilities of controlling hospital infection.METHODS Sputum culture was conducted for 51 respiratory tract infection patients with nosocomial infections,among which,the bacteriological culture of all parts of traditional oxygen-humidified bottles therapy were taken.Meanwhile the samples of bacteriological culture were collected from 98 cases of...
