| 摘 要： | 目的评估一种新型稳定中性电位水的理化性质,观察其对烧伤科院内感染常见多重耐药病原菌的灭活作用。方法选择新鲜配制(配制1个月)和保存8个月的新型稳定中性电位水作为待测样液,以有效氯含量、氧化还原电位(ORP)值和pH值等指标评估理化性质,观察长时间保存对其理化性质的影响;采用活菌培养计数的方法观察烧伤科院内感染常见的多重耐药病原菌(耐甲氧西林金黄色葡萄球菌、铜绿假单胞菌和鲍曼不动杆菌流行克隆株)在添加新型稳定中性电位水的培养皿上的菌落生长情况,以无菌生理盐水代替中性电位水作为阳性对照进行平行试验。结果新鲜配制和保存8个月的新型稳定中性电位水待测样液的pH值为6.0~7.0,有效氯含量为50~100 mg/L,ORP值>800 mV,理化性质无明显变化。活菌培养计数结果显示:添加新鲜配制和保存8个月的新型稳定中性电位水的培养皿上均未见菌落生长。结论新型稳定中性电位水的刺激性小,理化性质稳定,灭菌效果理想,可作为烧伤科环境及与患者密切接触物品的消毒剂。 |
