目的研究两种不同的消毒包装方法对氧气湿化瓶的消毒效果和保存期限影响,选择一个最佳消毒包装方案,降低医院感染的发生率。方法采用棉拭涂抹采样和细菌定量检测方法,对集中清洗消毒包装常规流程法和集中消毒包装优化流程法消毒保存氧气湿化瓶的效果进行了对比观察。结果经优化流程法消毒干燥后的氧气湿化瓶消毒合格率100%,保存7 d后的氧气湿化瓶保持良好率98.3%。经常规流程法消毒干燥后的氧气湿化瓶消毒平均合格率为95%,保存7 d后的氧气湿化瓶保持良好率平均为75%。结论优化流程法对氧气湿化瓶的消毒和保存效果明显优于常规流程法,前者消毒效果有保证,保存期限长。
Objective To study the effects of two different methods of disinfection and packaging on the disinfection effect and shelf life of oxygen humidification bottles and choose an optimal sterilization package to reduce the incidence of nosocomial infections. Methods Cotton swab smear sampling and bacterial quantitative detection methods were used to compare the effects of conventional cleaning and sterilizing packaging process and concentrated disinfection packaging process. Results The oxygen humidification bottle disinfection and drying rate was 100% after optimized and disinfected, and the oxygen humidification bottle maintained good rate of 98.3% after 7 days of storage. The average pass rate of the disinfection of oxygen humidification bottles disinfected and dried by the conventional method was 95%, and the oxygen humidification bottles maintained a good rate of 75% on average after 7 days of storage. Conclusion Optimization of the method of disinfection and preservation of oxygen bottles was significantly better than the conventional flow method, the former disinfection effect is guaranteed, long shelf life.
