摘要
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
In order to investigate the pollution of mural oxygen tube equipment and reasons, sampling inspection of some mural oxygen tube equipment, the one off joints of oxygen tube, and the spare humectant was performed separately. In the observation group, the humectant with preservation not more than 24 h after sterilization was used and the one off joints of oxygen tube replaced after the oxygen inhalation equipment was sterilized. In the control group, the humectant with preservation for 48 h was used and the one off joints of oxygen tube was not replaced. Twenty four h later, the pollution state of the oxygen inhalation equipment was compared between the two groups. The results showed that the pollution rate of the cap on the humectant bottle and the exit of oxygen tube was 81 0%, and that of the inner wall of the air tube was 89 0%. The occurrence of polluted joints was increased as the time passed by. Germiculture of the sterile humectant stored for 24 h and its container showed negative, but it showed positive for that stored for 48 h. The observation had a pollution rate of 10 0%, while the control group had a pollution rate of 73 3%, there was very significant difference between the two groups ( P <0 01). It was suggested that the mural oxygen tube equipment sterilization should be emphasized, spare humectant be stored less than 24 h, and the one off joints of oxygen tube replaced every 3 d.
