摘要
目的探索医院普通病房连续使用中的氧驱动雾化器污染的原因,并制定预防措施。方法随机检测连续使用中的氧驱动雾化器的面罩、储药杯和通气管,并追查污染的原因。结果在检测的50副雾化器中,面罩污染最严重,污染率为48.0%,其中14只检测出致病菌,主要有表皮葡萄球菌、肺炎克雷伯菌、大肠埃希菌;储药杯的污染率为30.2%,其中7只检出白色念珠菌、甲型溶血性链球菌;通气管污染率为18.0%,其中2只检测出肺炎克雷伯菌、白色念珠菌。雾化器各部件用洗洁精刷洗干净后,经1000 mg/L的含氯消毒剂浸泡30 min,清水冲洗15 min,晾干后,随机抽取30副雾化器各部件检测,其结果全部符合医院Ⅱ类环境物品卫生标准要求。结论清洁、消毒观念错误以及用后存放不当是引起雾化器污染的主要原因;严格消毒,正确存放,定期进行细菌检测,在规定的期限内使用是避免细菌污染的可靠措施。
Objective To explore contamination reasons of oxygen-driving atomizers used continuously in ordinary sickrooms of hospital, and formulate preventing measures. Methods Veils, medicine cups and air pipes of atomizers that used continuously were detected randomly, contamination reasons were further tracked down. Results Among 50 atomizers detected, veils were con- taminated most severely with a rate of 48.0% , 14 of them showed pathogenic bacteria, mainly Staphylococcus epidermidis, K. pneumoniae and Escherichia coll. The contamination rate of medicine cups was 30.2%, 7 cups infected with Candida albicans and （x-hemolytic streptococcus. Air pipes＇ contamination accounted for 18.0% ,2 pipes existed K. pneumoniae and Candida albicans. All parts of atomizers were scrubed with cleanser essence, then were soaked in 1 000 mg/L chlorine-releasing disinfectant 30 minutes, and then were washed with water for 15 minutes. After dry,30 atomizers＇ parts were drawn at random, and their detect results completely met the hygienic standard requirement of hospital type Ⅱ environment. Conclusion The main contamination reasons of atomizer were misconception of clean and sterilization, improper storage. Correct sterilization, proper storage, bacterial detection regularly and use in specified period were the reliable methods refraining from bacteria contamination.
