What is Ethylene Oxide primarily used for in surgical settings?

• A. A chemical for high-temperature sterilization
• B. B general purpose sterilant for heat or moisture-sensitive items
• C. C a gas used for disinfection of surfaces
• D. D a preservative for surgical instruments

Answer: (B)

Ethylene Oxide is primarily used as a general-purpose sterilant for heat or moisture-sensitive items due to its effective ability to sterilize these materials without causing damage. This is particularly crucial in surgical settings where instruments and equipment made of plastics or other sensitive materials require disinfection but cannot withstand the high temperatures of autoclaving or traditional steam sterilization methods.

The gas penetrates packaging materials and is capable of reaching the surfaces of instruments even within complex configurations. This ensures a thorough sterilization process, making Ethylene Oxide a valuable option for sterilizing items like delicate surgical instruments, electronic devices, and other materials that may be adversely affected by heat or moisture.

Its use is well-regulated, and safety precautions are necessary due to the toxic nature of Ethylene Oxide. Nonetheless, its efficiency in sterilization, paired with its compatibility with a wide range of materials, firmly establishes its role in maintaining surgical sterility while protecting sensitive instruments and devices.
