Which method is preferred for sterilizing heat-sensitive items?

Chemical sterilization is the preferred method for sterilizing heat-sensitive items because it uses chemical agents to achieve sterilization without exposing the items to high temperatures. Many heat-sensitive medical and dental instruments, such as those made of plastic or certain delicate electronics, cannot withstand the high heat of autoclaves or dry heat sterilization, which can cause damage or degradation of the materials.

In chemical sterilization, substances such as ethylene oxide or hydrogen peroxide gas are employed. These chemicals can penetrate packaging, ensuring that even intricate instruments are effectively sterilized while maintaining their integrity. This method is particularly useful in settings where sterilization needs to occur without compromising the function of the devices or instruments being used.

Other methods like autoclaving, dry heat sterilization, and steam sterilization are effective for items that can handle high temperatures and moisture but are not suitable for heat-sensitive materials. Each of these methods targets different types of materials and requires specific conditions that may not be safe for all types of equipment.
