1998年 ,对济宁市市直医院使用中的含 0 75 %有效碘碘酊溶液采样 ,测定其有效碘含量 ,并以 0 5 %硫代硫酸钠溶液中和后 ,检测其污染细菌总数及致病菌。结果 ,使用至 3天 ,近 1 / 3溶液有效碘含量 0 75 % ,2 1 4%样本污染细菌总数超标 ( 1 0 0ｃｆｕ/ｍｌ) ,致病菌检出率 In 1998, the iodine solution containing 0 75 % of iodized iodine used in the municipal hospital of Jining City was sampled and its effective iodine content was measured. After neutralization with a solution of 0.5% sodium thiosulfate, the total number of contaminating bacteria and pathogenic bacteria were detected. . As a result, the effective iodine content in nearly 1/3 of the solution was 0 75% after 3 days of use, and the total number of contaminated bacteria in 2 1 4% samples exceeded the standard ( 1 0 0 cfu/ml). The detection rate of pathogenic bacteria was
