2种灭菌器在消毒供应中心的应用比较

Comparison on application value of two kinds of sterilizers in central sterile supply department

目的探讨过氧化氢等离子低温灭菌与环氧乙烷灭菌在消毒供应中心的应用效果。方法 300个待灭菌包随机分为A、B组,各150个。A组采用过氧化氢等离子灭菌,B组采用环氧乙烷灭菌器灭菌,对比2种灭菌方法的灭菌效果、灭菌成本、灭菌时间。结果 2组均成功灭菌,灭菌合格率100%,A组灭菌耗时55 min,单个灭菌包成本73.16元人民币,B组灭菌耗时18 h,单个灭菌包成本17.58元人民币。结论过氧化氢等离子低温灭菌用时短,腔体小,更适合急需使用的手术器械的灭菌,环氧乙烷灭菌腔体容积大,装载物品多,灭菌成本低,适用于灭菌周转相对较慢的物品。

Objective To compare the application of two kinds of low temperature sterilizers in central sterile supply department （ CSSD） . Methods Atotal of 300 sterilization packages randomly selected in CSSD were divided into group A and group B, with 150 sterilization packages in each group. The hydrogen peroxide plasma and ethylene oxide low temperature sterilization were used into group A and group B, respectively. The sterilization effect, costs and sterilization time of the two groups were compared. Results Both group A and B can conform to the requirements of the steriliza-tion, with a 100% of eligible sterilization rate. In group A, the sterilization time was 55 minutes and cost of each packs was 73. 16 RMB. In group B, the sterilization time was 18 h and cost of each packs was 17.58 RMB. Conclusion The sterilization time of Forhydrogen peroxide low temperature plasma sterilizer is comparatively shorter and cavity is relatively smaller, which makes it more suitable for e-mergent sterilization of surgical instruments. While ethylene oxide sterilization have longer process time and larger cavity, which makes it suitable for items with relatively slow sterilization cycle.
