Variables affecting simulated use determination of residual ethylene oxide in medical devices.
In autumn 1993, AAMI/ST/WG 63, Sterilization Residuals Working Group undertook the task of studying factors involved in determining the amount of residual ethylene oxide in medical devices after sterilization and developing a protocol for controlling the relevant variables. The protocol was evaluated by conducting a round robin study consisting of 8 participating laboratories from around the co...
متن کاملReaction of the sterilant, ethylene oxide, on plastics.
Ethylene oxide (ETO) in the form, "Cryoxcide,"' is used to sterilize surfaces and objects that cannot be treated with heat or corrosive chemicals. Cryoxcide is a gaseous formulation consisting of 11 per cent of ethylene oxide, 44.5 per cent of trichloromonofluoromethane (Freon 11), and 44.5 per cent of dichlorodifluoromethane (Freon 12). Cryoxcide is used at this laboratory to sterilize sensiti...
متن کاملEthylene oxide sterilization of medical devices: a review.
Ethylene oxide (EO) is a well-known sterilizing agent. However, only recently has its use significantly emerged, based on its range of applications in the field of new medical device development and sterilization. This paper describes the progress in terms of EO sterilization and concludes that it remains a promising field to explore and develop. The EO action mechanism and toxicity are analyze...
متن کاملDetermination of low-level residual ethylene oxide by using solid-phase microextraction and gas chromatography.
Current methods of analysis for ethylene oxide (EO) in medical devices include headspace and simulated-use extractions followed by gas chromatography with either a packed or a capillary column. The quantitation limits are about 0.5-1.0 microg/g for a packed column and about 0.1-0.2 microg/g for a capillary column. The current allowable levels of EO on medical devices sterilized with EO gas as o...
متن کاملEffect of Ethylene Oxide Functional Groups in PEBA-CNT Membranes on CO2/CH4 Mixed Gas Separation
Poly (ether-block-amide) /poly (ethylene glycol)/ carbon nanotubes mixed matrix membranes have been successfully fabricated using solvent evaporation method to determine the effect of ethylene oxide groups on the performance of produced membranes. The effects of CNTs (2-8 wt%) and PEG (up to 50 wt%)were investigated in both single and mixed gas test setup in different temperature and pressure. ...
