过氧化氢等离子低温灭菌效果观察

目的观察过氧化氢等离子低温灭菌技术、灭菌效果和临床应用情况。方法对157次使用美国强生STERRAD100S过氧化氢等离子低温灭菌系统进行监测。结果134次灭菌循环运行完成,23次循环被取消,完成灭菌循环的生物检测培养均为阴性,所有化学指示卡均变色完全。结论STERRAD100S过氧化氢等离子低温灭菌系统具有安全可靠的性能,在灭菌周期、药物残留、毒性等方面具有明显的优势,灭菌效果检测方法方便、有效,但过氧化氢等离子灭菌有一定局限性。

Efficiency of Low-temperature Sterilization Using Hydrogen Peroxide Plasma

OBJECTIVE To observe the efficiency of new low-temperature sterilization method using(hydrogen) peroxide gas plasma sterilization system.METHODS The hydrogen peroxide gas plasma sterilization system of STERRAD 100S was monitored for 157 sterilization cycles.RESULTS From them 134 cycles were(completed,) 23 cycles were(cancelled.) All cycles were completed with negative results either in biological culture or in chemical indicators.CONCLUSIONS The STERRAD Sterilization System involves the combined use of hydrogen peroxide and low-temperature gas plasma to sterilize most medical devices and materials rapidly and safely without leaving any toxic residues.As nursing develops,the new sterilization system is efficient and convenient.However,it also has own limitations.Therefore,it is desirable to fully understand the normal procedure of system according to the operation instruction.
