为了解壁式氧气管道装置的污染状况及污染原因。分别对壁式氧气管道装置、吸氧连接管及备用湿化液进行采样检测 ;同时设观察组与对照组 ,将吸氧装置消毒后 ,观察组使用消毒后存放 2 4h内的湿化液 ,更换吸氧连接管 ,对照组使用消毒后存放 48h的湿化液 ,不更换吸氧连接管 ,使用 2 4h后比较两组吸氧装置的污染程度。结果1湿化瓶盖、送氧管出口污染率为 81.0 % ,通气管内腔污染率为 89.0 % ;2吸氧连接管污染例数随使用时间的延长而增加 ;3无菌湿化液存放 2 4h,液体及容器内壁细菌培养为阴性 ,存放 48h细菌培养为阳性 ;4观察组污染率为 10 .0 % ,对照组为 73.3% ,两组比较 ,差异有极显著性意义 (P<0 .0 1)。提示壁式氧气管道装置的消毒应引起重视 ,备用湿化液存放应 <2 4h,吸氧连接管 3d更换 1次
In order to understand the pollution situation of wall oxygen pipeline device and the pollution reason. Respectively, the wall oxygen pipeline device, oxygen connection pipe and standby wetting fluid sampling and detection; while the observation group and the control group, the oxygen device disinfection, the observation group after disinfection storage within 24 hours of wetting fluid, Replace the oxygen connection pipe, the control group used after disinfection 48h wetting fluid, do not replace the oxygen connection pipe, the use of 2 4h after comparing the degree of contamination of oxygen inhalation devices. The results showed that: 1, the rate of contamination at the outlet of the humidification bottle cap and oxygen delivery tube was 81.0% and the contamination rate of the vent tube was 89.0%; 2, the number of pollution cases of oxygen connection tube increased with the extension of the use time; 3, 4h, the bacterial culture of the liquid and the inner wall of the container was negative, and the bacterial culture was positive 48h after storage; the contamination rate of the observation group was 10.0% and that of the control group was 73.3%. There was significant difference between the two groups (P <0. 0 1). Tips wall disinfection of oxygen pipeline device should pay attention to standby wetting fluid storage should be <24h, oxygen tube 3d replacement 1
