Which type of sterilization is commonly used for heat-sensitive items?

Ethylene oxide sterilization is the correct choice for heat-sensitive items because it utilizes a gaseous form of ethylene oxide to achieve sterilization at low temperatures. This method is particularly beneficial for items that might be damaged by high heat or moisture, such as certain plastics, electronic devices, and delicate instruments. Ethylene oxide is effective in penetrating materials and inactivating a broad spectrum of pathogens, including bacteria, viruses, and fungi, making it suitable for delicate medical equipment that must maintain its functional integrity.

Steam sterilization is effective but relies on high temperatures and moisture, which can damage heat-sensitive items. Radiation sterilization, while effective, is not commonly used for routine sterilization in many healthcare settings and may not be suitable for all types of materials. Dry heat sterilization also requires high temperatures for extended periods, making it inappropriate for heat-sensitive items as well.
