What is a disadvantage of using ethylene oxide for sterilization?

Ethylene oxide is commonly used for sterilization, particularly for complex medical devices that cannot withstand high temperatures. One of the significant disadvantages of using ethylene oxide for sterilization is its long cycle time. The process often requires several hours to complete, as it not only includes the exposure phase but also necessitates a thorough aeration phase to ensure that residual gas is eliminated before items are safe for handling. This lengthy process can hinder efficiency in settings where rapid turnaround of sterilized instruments is essential, making scheduling and workflow more challenging.

In contrast, the other characteristics listed highlight advantages rather than disadvantages. Ethylene oxide does not require special handling during the actual sterilization cycle, which can simplify the process. It also has a relatively short exposure time during the cycle, although the overall process is lengthy due to the required aeration period. Furthermore, ethylene oxide is considered non-flammable when used correctly, adding to its safety profile when handled in a controlled environment. Therefore, the disadvantage of ethylene oxide sterilization clearly centers around the long cycle time it imposes.
