摘要
目的 调查某医院麻醉机管路污染情况,并探讨去除污染的方法。方法 采用现场采样和细菌定量检测方法,对某医院手术室麻醉机管路进行细菌污染调查和消毒效果评价。结果 共调查13台麻醉机内部管路呼气端口和活瓣内口,细菌污染超标率分别为31.03%和57.69%。使用后的麻醉机管路采用过氧化氢汽化熏蒸消毒,以及用有效氯1 000 mg/L的含氯消毒液对管路外口处擦拭消毒,麻醉机管路呼气口和活瓣口的卫生合格率均高于消毒前(P<0.05)。患者年龄、经腔镜手术和俯卧位通气是污染麻醉机内部呼吸管路的高危因素。结论 所调查的麻醉机管路细菌污染超标严重,采用熏蒸和擦拭消毒可有效降低细菌污染。
Objective To investigate the contamination of anesthesia machine pipeline in a hospital and discuss the methods to remove contamination.Methods Field sampling and quantitative bacterial detection method were used to investigate bacterial contamination and assess the disinfection effect of the anesthesia pipeline in the operating room of a hospital.Results A total of 13 internal pipeline expiration ports and the inner port of the living valve was examined,and the excess rate of bacterial contamination was 31.03%and 57.69%,respectively.The anesthesia machine tubing was disinfected by hydrogen oxide vaporization fumigation,and the outer opening of the tubing was wiped and disinfected with chlorine containing disinfectant solution containing 1000 mg/L available chlorine.The hygiene qualification rates of the exhalation and valve openings of the anesthesia machine tubing afer disinfection were higher than that before disinfection(P<0.05).Age,laparoscopic surgery,and prone ventilation are all risk factors for contaminating the breathing circuits inside the anesthesia machine.Conclusion The bacterial contamination of the investigated anesthesia machine internal pipeline is serious,and the fumigation and cleaning disinfection can effectively reduce the bacterial contamination.
