Name two commonly used sterilization modalities in ASCs.

• A. Steam sterilization (moist heat) and low-temperature sterilization such as ethylene oxide or hydrogen peroxide plasma
• B. Ethylene oxide only
• C. Steam sterilization only
• D. Ultraviolet sterilization

Answer: (D)

In ASCs, sterilization relies on two main approaches: steam sterilization (moist heat) and low-temperature sterilization for heat- or moisture-sensitive instruments. Steam sterilization uses autoclaves with saturated steam under pressure, which is fast, reliable, and cost-effective for a wide range of instrument sets once they’re properly cleaned and wrapped. Biological indicators confirm sterility, and cycles are designed to handle typical packs and lumened instruments. For devices that can’t withstand heat or moisture, low-temperature modalities are used, such as ethylene oxide gas or hydrogen peroxide plasma. These options sterilize without high temperatures, though they require longer cycles and careful handling of residues and aeration. Ultraviolet sterilization is primarily a surface-disinfection method and has limited penetration; it can’t reliably sterilize wrapped loads or complex instruments. So it’s not considered a primary sterilization modality in most ASC settings.
