过氧化氢低温等离子灭菌器对消毒供应室器械的灭菌效果研究

摘要

目的 分析过氧化氢低温等离子灭菌器对消毒供应室器械的灭菌效果。方法 选择2020年1月-2023年1月消毒供应室器械包一共200份，将其按照随机数表方式分组，分为对照组（n=100，环氧乙烷气体灭菌法)和观察组（n=100，过氧化氢低温等离子灭菌器灭菌），对比两组灭菌效果。结果 观察组灭菌监测合格率明显高于对照组（P<0.05）为差异显著，有统计学意义。观察组灭菌循环周期明显短于对照组，24h内器械使用率和周转率明显高于对照组（P<0.05）为差异显著，有统计学意义。观察组灭菌时间明显更短，（P<0.05）为差异显著，有统计学意义。结论 过氧化氢低温等离子灭菌器对消毒供应室器械的灭菌效果较显著，能够提高灭菌效果，提高24h内器械使用率和周转率，值得积极应用。

Abstract

Objective To analyze the sterilization effect of hydrogen peroxide low temperature plasma sterilizer on the equipment in the disinfection supply room.
Methods A total of 200 equipment kits in the disinfection supply room from January 2020 to January 2023 were selected and divided into control group (n=100, ethylene oxide gas sterilization) and observation group (n=100, hydrogen peroxide low-temperature plasma sterilization) according to a random number table, and the sterilization effect of the two groups was compared.
Results The qualified rate of sterilization monitoring in the observation group was significantly higher than that in the control group (P<0.05), indicating a significant difference with statistical significance. The sterilization cycle of the observation group was significantly shorter than that of the control group, and the utilization rate and turnover rate of instruments within 24h were significantly higher than those of the control group (P<0.05), indicating significant differences with statistical significance. The sterilization time in the observation group was significantly shorter (P<0.05), indicating a significant difference and statistical significance.
Conclusion   Hydrogen peroxide low temperature plasma sterilizer has significant sterilization effect on disinfection supply room instruments, which can improve the sterilization effect, increase the utilization rate and turnover rate of instruments within 24h, and is worthy of active application.
