全效型多酶清洁剂在全自动清洗消毒器中的最佳程序选择

The exploration of optimum cycle of automatic washer disinfector for endozime auto wash triple plus with advanced proteolytic action

目的 探讨全效型多酶清洗剂在全自动清洗消毒器中的最优程序选择,以保证机械清洗质量,提高复用器械再次使用的安全性. 方法 对新升级的4号清洗消毒器,使用目测、STF清洗效果监测卡和三磷酸腺苷(ATP)荧光检测技术的方法验证其清洗效果,并每周次改进其关键参数,如预洗温度、预洗时间、清洗剂浓度、主洗温度、主洗时间、总漂洗时间,记录清洗结果,共3周次完成实验,依次记录为初始程序组、优化程序1组、优化程序2组.使用Χ2检验方法比较3组数据差异.结果 优化调整后的优化程序2组器械达到清洗效果最佳目测合格率为100.00%,ATP荧光检测合格率为100.00%,STF清洗效果监测卡全部通过.清洗效果较前2组明显改善,充分发挥了该清洁剂的效用.结论 清洗设备的程序参数能够提高手术器械的清洗质量,特定耗材需要进行验证,寻找其最佳清洗程序.

Objective To explore optimum cycle of Automatic Washer Disinfector for endozime auto wash triple plus with advanced proteolytic action to ensure mechanical cleaning quality and improve safety of reusable medical instruments. Methods Visual inspection, STF cleaning efficacy monitoring test and Adenosine Triphosphate (ATP) test were used to verify cleaning quality of the newly updated No.4 automatic washer disinfector, and changed key parameters on weekly basis, such as pre-cleaning temperature, pre-cleaning time, detergent concentration, main cleaning temperature, and main flushing time, recorded cleaning results for three weeks:Group test of initial procedure, Group test 1 of optimization procedure and Group test 2 of optimization procedure.Χ2 test was used to compare differences of the three groups and determine the optimum cycle. Results Group test 2 of optimization procedure had the highest visual inspection and ATP test qualification rate (both were 100.00%), and pass all the STF tests. Cleaning quality was significantly better than the other two groups, and the cycle made full use of the tested detergent. Conclusions Cycle parameters of cleaning machine have great impact on medical instruments cleaning quality; Specific consuming products need to be verified to determine the optimum cleaning cycle.
