两种不同含氯消毒剂对手术器械的锈蚀反应及消毒效果观察

摘要

Objective To observe the corrosion reaction and disinfection effect of the two different chlorine disinfectants toward the surgical instruments, to prevent the corrosion of instruments and the professional infection risk of cleaning staffs during washing the infectious disease-contaminated medical instruments manually in the primary hospitals. Methods The surgical instruments were soaked in the diluted chlorine effervescent tablets and the diluted chlorine disinfection powder, respectively. The corrosion of the two disinfectants to the equipment at different times was observed. The bloody surgical instruments were soaked in the diluted chlorine effervescent tablets and the chlorine disinfection powder for 4 hrs, respectively. The instruments' surfaces status was observed,and the bacterial reproduction status after soaking the instruments in the diluted liquid for 48 hrs was monitored.Results The diluted liquid of effervescent chlorine tablets had corrosion reaction after only 5- 10 minutes,but the diluted liquid of chlorine disinfection powder had no corrosion reaction after 48 hours. The dilution liquid of effervescent tablets and the dilution liquid of disinfection powder had a significant statistic difference in the rate of instruments corrosion. The bloody instruments' surface had difference after immersed for 4 hrs,and the pass rates of bacteria monitor was 100% after 48 hrs of immersion. Conclusions For the primary hospitals without cleansing and disinfection equipments,using the chlorine disinfection powder to soak the medical instruments before cleaning the infectious disease-contaminated medical instruments manually not only has no equipment corrosion but also achieves the disinfection effect.%目的 观察两种不同含氯消毒剂对手术器械的锈蚀反应及消毒效果.使基层医院在手工清洗传染病污染器械过程中,既可防止器械产生锈蚀,又可避免清洗人员职业感染风险.方法 分别采用含氯泡腾片、含氯消毒粉稀释液浸泡手术器械.观察两组消毒剂不同时间对器械产生锈蚀情况;分别采用含氯泡腾片、含氯消毒粉稀释液浸泡血液污染器械4 h,观察器械表层情况及其两组消毒液存放48 h细菌监测情况.结果 含氯泡腾片稀释液浸泡器械仅5-10 min开始起锈蚀反应,而含氯消毒粉稀释液浸泡器械48 h则无锈蚀反应;泡腾片稀释液与消毒粉稀释液相比较其器械锈蚀率差异有统计学意义;两组消毒液分别浸泡血液污染器械4 h,其器械表层情况有差异;其两组消毒液存放48 h细菌监测合格率均达100%.结论 基层医院无清洗消毒设备时.用手工清洗传染病污染的器械前,使用含氯消毒粉稀释液浸泡器械,既不使器械产生锈蚀.又可达到消毒效果.
