Abstract:
Objective To observe the effects of Class 5 and 6 chemical indicative cards used for monitoring pressure steam sterilization to standardize the procedure for selecting the monitoring substance of pressure steam sterilization. Methods Several pieces of Class 5 and 6 cards were placed at the four corners and center of the clave to undergo sterilization with the conventional parameters of 134 ℃, 240 s and 220 kPa as well as the simulation critical parameters of 134 ℃, 120 s and 220 kPa.The two kinds of cards had their qualification rates compared with two sets of parameters.SPSS 19.0 software was used for data analysis and Chi-square test was applied to comparison.Results The two kinds of cards had the qualification rates being 100% with the conventional parameters;with the simulation critical parameters,Class 5 card had the qualification rate being 100%,while Class 6 card had the rate of 66.67%,and there were significant difference between the qualification rates of the two cards(P<0.05).Conclusion Class 6 chemical indicative card has higher resistance and efficiency with the same conditions when compared with Class 5 card,which can be combined with the tube cavity challenger to execute mass monitoring with unstable parameters.
