ABSTRACT
OBJECTIVE To apply a low temperature hydrogen peroxide gas plasma sterilization for the heat intolerant orthopedic instruments.METHODS A comparison of the sterilizing effects of the orthopedic(instruments) was made among the low temperature hydrogen peroxide gas plasma sterilization,the ethylene oxide sterilization and the 2% glutaraldehyte(GTA).RESULTS Twelve hours were spent in the sterilization to the undurable(orthopedic) instruments when the ethylene oxide was used,and 10h were needed using the 2%GTA.but,55 min were enough using the low temperature hydrogen peroxide gas plasma.CONCLUSIONS The low temperature(hydrogen) peroxide gas plasma sterilization is applicable to rapidly sterilizing the heat undurable orthopedic(instruments) characteristically with the high effects,quick speed and convenient.
ABSTRACT
Objective To evaluate the efficacy of STERRAD (r) 100S (low temperature hydrogen peroxide gas plasma sterilization system) by comparing with formaldehyde steam. Methods From 2005.1 to 2005.3, totally sterilization of 2 760 pieces of operating tools were carried out with formaldehyde steam. From 2005.1 to 2005.3, totally sterilization of 4 950 pieces of operating tools in 180 circles were carried out with STERRAD (r) 100S. The instrument damage rate, operating infection rate and satisfaction rate of medical workers of 2 groups were compared. Results All data were in favor of the efficacy of STERRAD (r) 100S. Conclusions STERRAD (r) 100S is a safe, effective, low temperature, and cost-effective sterilization system..
ABSTRACT
OBJECTIVE To monitor the sterilization effect of hydrogen peroxide gas plasma sterilizer with process challenge derice(PCD).METHODS Hydrogen peroxide gas plasma sterilizer was used to sterilize different material and structure items in simulation field sterilization trial.The test pieces have been cultured for 7 days at 37 ℃.Make the test records in detail.RESULTS The hemostatic forceps,surface of lines and biological indicators,as well as 300 mm stainless steels tube and 2000 mm Teflon tube were sterilized successful.But 600 mm and 300 mm stainless steels of low temperature did not past the challenge tests.The results of test surface and test lumen were inconsistent.CONCLUSIONS PCD is need to be introduced in monitoring sterilization effect of hydrogen peroxide gas plasma sterilizer.
