含氯消毒剂对手术器械残余血清洗效果观察

目的 探讨既经济又方便的方法解决手术器械的残余血问题,减少院内感染.方法 把术后手术器械分为4组,分别采用4种方法清洗术后器械:传统清洗方法;传统方法清洗后,放入含有效氯334 mg/L的健之素消毒液中浸泡10 min;传统法清洗后,放入含有效氯250 mg/L的健之素消毒液中浸泡10 min;传统法清洗后,放入含有效氯250 mg/L的健之素消毒液中浸泡15 min.手术器械按上述4种方法清洗冲净擦干后分别对器械表面、轴关节、咬合齿、管腔进行隐血测试.结果 传统方法清洗后,放人含有效氯334 mg/L的健之素消毒液中浸泡10 min或放入含有效氯250 mg/L的健之素消毒液中浸泡15 min,手术器械各个部位合格率均为100%,而传统方法清洗合格率全部为0,而传统法清洗后,放入含有效氯250 mg/L的健之素消毒液中浸泡10min,只有器械表面的合格率是100%,其他部位均存在不合格的情况.结论 用含有效氯334 mg/L的健之素消毒液浸泡传统方法清洗后的手术器械10 min或含有效氯250 mg/L的健之素消毒液浸泡15 min,能有效去除残余血.

The Effect of Chlorine Disinfectants in Cleaning Remaining Blood on Operation Apparatus

Objective To find an economical and convenient method to clean remaining blood on operation apparatus to reduce nosocomial infections.Methods The used operation apparatus was divided into 4 groups,each cleaned with a respective blood cleaning method: conventional method alone;conventional method plus soaking in 334 mg/L chlorine disinfectant(Jianzhisu) for 15 min;conventional method plus soaking in 250 mg/L chlorine disinfectant for 10 min and conventional method plus soaking in 250 mg/L cholorine disinfectant for 15 min.Then occult blood test was performed on the surface,axis,occlusion and lumen.Results The apparatus cleaned with conventional method plus soaking with 334 mg/L chlorine disinfectant for 10 min or with 250 mg/L chlorine disinfectant for 15 min amounted to a checkout rate of 100% at all tested parts.The checkout rate for the conventional method alone was zero and that for the conventional method plus 250 mg/L chlorine disinfectant of 10 min reached a checkout rate of 100% only on the surface but unsatisfactory at other parts.Conclusion The cleaning methods of conventional method plus soaking in 334 mg/L chlorine disinfectant for 15 min or soaking in 250 mg/L cholorine disinfectant for 15 min may effectively clean the remaining blood on the apparatus.
