摘　　要：目的观察气管插管全麻手术医院内下呼吸道感染的相关因素,作好消毒管理。方法采用现场采样和实验室检验方法,对麻醉机内部元件及相关麻醉用品自然菌污染和人工菌杀灭效果进行了检测。结果患者呼出的气体经过一次性病毒/细菌过滤器过滤后进入呼吸回路的管道,细菌明显减少,一次性呼吸回路管道未能检出细菌。麻醉机内部的螺纹管、气阀均未检出致病菌。麻醉机内部的二氧化碳吸收剂(钠石灰)对细菌繁殖体、结核分枝杆菌和细菌芽孢均具有一定杀灭作用。结论麻醉用品的病毒/细菌过滤器对进入病人的呼吸道微生物具有一定过滤效果,管路中的二氧化碳吸收剂具有一定杀菌作用。Objective To observe the risk factor for the nosocomial lower respiratory tract infections resulting from general anesthesia with tracheal intubation. Methods On - the - spot sampling and laboratory examination method were used to examine the efficacy in killing the natural and artificially contaminating bacteria collected from the anesthesia supplies and anesthesia machines. Results The microorganisms in gas exhaled by patients in the breathing passage way were reduced significantly after filtration with disposable virus/bacterial filter and could note be detected in disposable respiratory circuit pipe. Also, in the thread pipes and valves in the anesthesia machine the pathogens could not be detected. Conclution The CO2 absorbent （ soda lime ） in anesthesia machines had certain killing effect on the vegetative form of bacteria, Myeobacterium tuberculosis and bacterial spores. Conclusion The virus / bacterial filter possesses certain filtering efficacy. CO2 absorbent in passage way possesses certain germicidal effect.
