摘　　要：为检测医院应用中消毒液微生物污染情况及聚维酮碘和碘酊的杀菌效果 ,采用随机抽检和载体定量杀菌试验进行了观察。结果 ,使用中消毒液细菌总数超标率为 1.7%～ 14 .17% ,消毒液中污染菌以洋葱假单胞菌和微球菌为主。含有效碘 5 0 0 0mg/L的聚维酮碘和 2 0g/L有效碘的碘酊作用 10min ,对大肠杆菌和金黄色葡萄球菌杀灭率为 10 0 %。二者杀菌效果无显著性差异。结果显示 ,临床科室应用的消毒液存在污染情况 。In order to examine microorganism contamination of disinfectant solutions in use in hospital and the germicidal efficacy of povidone iodine and iodine tincture, random sampling examination and carrier quantitative germicidal test were used for observation. The results showed that the rate of total bacterial count exceeding the allowable limit in disinfectant solutions in use was 1.7%～14.17%. The contaminating bacteria in the disinfectant solutions were mainly Pseudomonas cepacia and Micrococcus. Povidone iodine containing available iodine 5000 mg/L and iodine tincture containing available iodine 20 g/L with a 10 min contact time killed 100% of Escherichia coli and Staphylococcus aureus. The germicidal efficacy of these two disinfectants did not differ significantly from each other. The results indicated that the disinfectant solutions in use in clinical departments were contaminated. The germicidal efficacy of povidone iodine and iodine tincture used clinically was essentially identical.
