摘　　要：目的：了解麻醉机螺纹管，呼气活瓣的细菌污染状况。方法：采用横断面研究方法，分两次对本院18台（共36台／次）麻醉机螺纹管．呼气活瓣进行采样；采用普通细菌培养法对样本进行细菌培养．菌落计数．使用纲菌鉴定分析仪对细菌进行鉴定。结果：2台，／次麻醉机螺纹管检出细菌，均为洛菲不动杆菌（菌落计数〉200cfu）麻醉机呼气活瓣未检出细菌。结论：麻醉机螺纹管可能是全麻手术患者术后感染的危险因素之一。Objective：Test the contamination of the corrugated tubes and expiratory valves of anesthesia machines. Methods：Adopt the cross-sectional study, take samples from corrugated tubes and expiratory valves of 18 anesthesia machines in our hospital twice（totally 36）.Samples were cultured with conventional culture ways,and bacterial colonies were counted. Bacterial identify analyzer was applies to identify bacterium. Results：Bacterium was detectived on two samples of corrugated tubes,all are Iwoffl（bacterial colonies〉200cfu）.No bacterium was detectived on expiratory valves. Conclusions：Corrugated tubes maybe one cause of the infections for patients who received general anesthesia.
