Common Sterilization Methods And Techniques Used By Sterile Processing Professionals

Sterilization is a critical aspect of healthcare and medical services, and it is the responsibility of sterile processing technicians to ensure that medical equipment and instruments are free from contaminants and pathogens. In this article, we’ll explore the various sterilization methods and techniques used by sterile processing technicians to maintain a safe and healthy environment for patients and healthcare workers.

Steam Sterilization

Steam sterilization, also known as autoclaving, is one of the most common sterilization methods used in healthcare facilities. This process involves subjecting medical instruments and equipment to high-pressure steam at a temperature of 121°C (250°F) for a specific period of time, which kills all microorganisms, including bacteria, viruses, and spores. Sterile processing programs teach students that steam sterilization is highly effective and is suitable for most types of medical equipment.

Ethylene Oxide Sterilization

Ethylene oxide sterilization is a low-temperature sterilization method that is commonly used for heat-sensitive equipment and materials, such as plastics, electronics, and textiles. This process involves exposing the items to a mixture of ethylene oxide gas and other gasses at a temperature of 37°C (99°F) for several hours, which kills all microorganisms. Proper use of ethylene oxide is taught in the central service technician program. Ethylene oxide sterilization is highly effective but requires specialized equipment and handling procedures.

Hydrogen Peroxide Sterilization

Hydrogen peroxide sterilization is a low-temperature sterilization method that uses a vaporized hydrogen peroxide gas to sterilize medical instruments and equipment. This process involves exposing the items to the gas at a temperature of around 55°C (131°F) for several hours, which kills all microorganisms. Sterile processing students learn to work with hydrogen peroxide in a sterile processing program. Hydrogen peroxide sterilization is highly effective and is commonly used for heat-sensitive equipment and materials.

Plasma Sterilization

Plasma sterilization is a low-temperature sterilization method that uses plasma gas to sterilize medical instruments and equipment. This process involves exposing the items to a low-pressure plasma gas at a temperature of around 45°C (113°F) for a short period, which kills all microorganisms. Plasma sterilization is highly effective and is suitable for most types of medical equipment. The Central service technician program teaches students the process of plasma sterilization.

Gamma Radiation Sterilization

Gamma radiation sterilization is a high-energy radiation method that is commonly used for medical instruments and equipment that are heat-sensitive or cannot withstand other sterilization methods. This process involves exposing the items to gamma radiation, which damages the DNA of microorganisms, rendering them unable to reproduce. Gamma radiation sterilization is highly effective but requires specialized equipment and handling procedures. Students learn how to handle the specialized equipment in the sterile processing program. 

Chemical Sterilization

Chemical sterilization is a sterilization method that uses chemical agents to sterilize medical instruments and equipment. This process involves immersing the items in a chemical solution or gas, which kills all microorganisms. Chemical sterilization is highly effective and is commonly used for heat-sensitive equipment and materials. Sterile processing training is important to avoid hazards while working with heat with chemicals.

Ultraviolet (UV) Sterilization

Sterile processing training teaches UV sterilization to the students in a supervised environment. Ultraviolet (UV) sterilization is a low-temperature sterilization method that uses ultraviolet light to kill microorganisms. This process involves exposing the items to UV light at a specific wavelength, which damages the DNA of microorganisms, rendering them unable to reproduce. UV sterilization is effective for surface disinfection but is not suitable for sterilizing medical equipment and instruments.

Dry Heat Sterilization

Dry heat sterilization is a sterilization method that uses high temperatures to sterilize medical instruments and equipment. This process involves subjecting the items to dry heat at a temperature of around 160°C (320°F) for a specific period of time, which kills all microorganisms. Dry heat sterilization is highly effective but is not suitable for all types of medical equipment and instruments.

Conclusion

Sterile processing technicians must know the different sterilization methods. With advancement in technology sterilization methods have evolved. Sterile processing technician certification at PTTI helps sterile processing fiends stay up to date.
