What is the primary disadvantage of ethylene oxide sterilization?

• A. It requires high temperatures to be effective
• B. It leaves toxic residues on instruments
• C. It necessitates a lengthy aeration time to remove gas residuals
• D. It is ineffective for certain types of plastic

Answer: (C)

The primary disadvantage of ethylene oxide sterilization lies in the necessity for a lengthy aeration time to effectively remove gas residuals. This process is critical because ethylene oxide (EtO) is a potent alkylating agent that can pose health risks if not properly eliminated from sterilized items. After the sterilization cycle, instruments must undergo a significant aeration period to ensure that all EtO has dissipated, making them safe for use. This aeration step is time-consuming, which can delay the availability of sterile items and impact workflow in healthcare settings. The lengthy aeration time is considered a significant drawback compared to other sterilization methods that may not require such extensive preparation before use. It highlights the importance of balancing sterilization effectiveness with practicality in a clinical environment.
