目的重复使用的氧气湿化装置与一次性氧气湿化装置进行使用后细菌学分析.方法随机抽取老年科6个病区用后的可重复使用的氧气湿化装置与一次性氧气湿化瓶,将吸氧患者随机分为3组,A组用冷开水作为氧气湿化液,B组用蒸馏水作为氧气湿化液,C组用AQUAPAK一次性氧气湿化装置.A组和B组在每周一和周四更换湿化瓶前采样,C组在每瓶一次性氧气湿化装置使用结束后采样,按<医院消毒卫生标准>消毒液的采样方法采样后送检验科检验.结果 A组61个样本中带菌率为81.97%,B组71个样本中带菌率为47.89%,C组52个样本中带菌率为0.3种湿化瓶使用后的污染率比较差异显著.A,B组间进行比较,A组细菌平均严重等级高于B组,A组革兰阴性菌种类的等级及革兰阳性菌的带菌率均高于B组.结论无论是用冷开水还是蒸馏水作为氧气湿化液,湿化液均有不同程度的污染,在目前各医疗机构尚无统一湿化液选择标准以及消毒规范的背景下,对长期吸氧的患者,建议选择一次性氧气湿化装置,以期减少患者院内感染的发生率.

Objective To carry out bacteriological analysis between re-used and disposable oxygen humidification devices. Methods Reused oxygen equipment and disposable oxygen moisture bottles from 6 randomly selected elderly wards were collected, patients who used oxygen will be randomized into 3 groups, group A used cold water as the oxygen humidification liquid, group B used distilled water as humidification liquid, group C used AQUAPAK disposable oxygen humidification devices, sample taking in group A and group B happened on every Monday and Thursday before the replacement of sample moisture bottles, sample was taken in group C after the use of disposable oxygen humidification devices, according to "hospital disinfection health standards" (GB5982-1995)sampling method of disinfection liquid sample was taken and sent to test in the disinfectant laboratory. Results Of 61 samples in group A bacteria cartier rate was 81.97%, bacteria carrier rate of 71 samples in group B was 47.89%, of 52 samples in group C the carrier rate was 0. The comparing of bacterial contamination rate of three kinds of oxygen moisture bottles after using was statistically significant. Take group A, B for comparison, the average severity level of bacteria in group A is higher than group B. In group A, the level of the Gram-negative bacteria as well as Gram-positive bacteria colonization was higher than group B. Conclusions Whether use of cold water or distilled water, oxygen humidification liquids have different degrees of pollution. Currently there is no general criteria and norms in the context of sterilization of oxygen humidification, for patients on long-term oxygen using, to choose disposable oxygen humidification device to reduce the incidence of hospital infections is recommended.
