手术室环氧乙烷灭菌生物监测方法的改进

Biomonitoring Ethylene Oxide Sterilization Process and Reason of Sterilization Failure

目的通过环氧乙烷生物灭菌监测方法的改进与分析,找出监测的影响因素及正确使用方法,指导今后更好地开展此项工作。方法对2007年5-12月手术室环氧乙烷灭菌生物指示剂监测结果进行分析。结果监测环氧乙烷灭菌包共计210例,合格202例,占96.1%,不合格8例,占3.9%。结论操作人员必须严格执行操作规程,掌握灭菌器的使用方法,确保生物指示剂监测合格,从而保证环氧乙烷、灭菌器的安全使用,提高环氧乙烷消毒物品的灭菌质量。

OBJECTIVE Through biomonitoring the effect of ethylene oxide sterilization process, to discuss the precision usage and management of the technology in operating room, and instruct the sterile job in operating room in the future. METHODS The process of ethylene oxide sterilization was monitored by biological indicators to realize the whole controlling of sterilization effects. RESULTS In the whole 210 sterile articles, 202 were qualified, and 8 were disqualified. CONCLUSIONS With correct procedures of sterilization and assurance the qualification of the biomonitoring indicators, the optimal quality of sterilization would be achieved.
