胆道镜低温等离子灭菌失败原因分析

Causes of failure of sterilization of choledochoscopes with low temperature plasma

目的对应用低温等离子灭菌系统灭菌胆道镜运行情况进行统计分析,探讨失败原因及对策,以期提高胆道镜一次通过灭菌程序的成功率,提高胆道镜使用率。方法对手术室2010年10月-2012年9月325次使用低温等离子灭菌系统灭菌胆道镜进行回顾性统计分析,对循环终止发生的时段、类型、频率等进行分析,查找失败的原因。结果 325次灭菌胆道镜中303次灭菌成功,成功率93.2%,失败22次,失败率6.8%,失败原因与胆道镜的清洗不彻底、潮湿、包装和装载不符、等离子灭菌器机械故障等有关。结论通过采取严格规范清洗、高压气枪汽化干燥、加强包装、装裁、仪器保养和维护等相应的管理对策,可以提高低温等离子灭菌器用于灭菌胆道镜的成功率。

OBJECTIVE To investigate the running state of low temperature plasma sterilization system used for sterilization of choledochoscopes sterilization and expolore the causes of failure of sterilization so as to improve the success rate of first time sterilization as well as the utilization rate of choledochoscopes .METHODS From Oct 2010 to Sep 2012 ,totally 325 times of sterilization of choledochoscope with low temperature plasma sterilization systems were retrospectively analyzed ,then the time of circular termination ,types ,and frequency were analyzed ,and the causes of failure were found out .RESULTS Of the 325 times of sterilization of choledochoscopes ,303 times have succeeded with the success rate of 93 .2% ,while 22 times failed with the failure rate of 6 .8% ,and the causes of the failure of sterilization included the incomplete cleaning of choledochoscopes ,wet packaging ,unmatched load-ing ,and mechanical failure of plasma sterilizer .CONCLUSION The strict and standard cleaning ,high pressure air gun boiling dry ,standard packaging and loading ,and intensified care and maintenance of instruments can improve the success rate of sterilization of choledochoscopes .
