目的研究环氧乙烷灭菌体灭菌失败的原因,探讨相应的改进措施。方法统计2013年9月-2014年12月医院使用环氧乙烷灭菌的情况,综合分析灭菌失败的原因,对存在的问题进行计划、实践、检查、反馈及持续改进。结果持续应用PDCA循环法15个月中,环氧乙烷灭菌失败率由14.0%下降至0。结论 PDCA循环法可以帮助管理者确定灭菌失败的真正原因,解决包内化学指示物变色不合格现象,保证灭菌质量,为临床提供安全可靠的无菌物品。
Objective To study the reason of sterilization failure of ethylene oxide sterilizers and to discuss the corresponding improvement measures. Methods Statistics of hospital use of ethylene oxide sterilization from September 2013 to December 2014 were conducted. The causes of sterilization failure were comprehensively analyzed, and the existing problems were planned, practiced, checked, feedbacked and continually improved. Results In the 15 months after continuous application of the PDCA cycle method, the failure rate of ethylene oxide sterilization decreased from 14.0% to 0%. Conclusions The PDCA cycle method can help managers to determine the true cause of sterilization failure, resolve the discoloration of chemical indicators in the package, ensure the quality of sterilization, and provide safe and reliable sterile products for clinical use.
