Traditional Technologies in Sterile Processing

Traditional technologies have formed the backbone of sterile processing for decades. Their longstanding use is a testament to their effectiveness. Some of the hallmark traditional methods include:

  1. Steam Sterilization: This method uses pressurized steam to kill microorganisms. Its efficacy, simplicity, and speed make it a widely adopted method, especially for heat-resistant instruments.
  2. Ethylene Oxide (EtO) Sterilization: Ideal for heat-sensitive instruments, EtO is a gas that destroys microorganisms by disrupting their cellular metabolism. However, it requires longer cycle times and post-processing aeration.
  3. Dry Heat Sterilization: This method exposes instruments to high temperatures for an extended period. It’s primarily used for materials that might corrode with steam sterilization.

Emerging Technologies in Sterile Processing

Innovation in sterile processing has brought forward a range of new technologies, aiming to address the limitations of traditional methods and to optimize the sterilization process.

  1. Hydrogen Peroxide Gas Plasma Sterilization: This technology uses hydrogen peroxide vapor and an electric field to create a plasma cloud. The reactive species in this cloud effectively destroy microorganisms. It’s faster than EtO sterilization and doesn’t leave toxic residues.
  2. Peracetic Acid Immersion Sterilization: This method immerses instruments in a solution of peracetic acid, offering rapid sterilization without the need for aeration.
  3. Ultrasonic Cleaning: While not a sterilization method per se, ultrasonic cleaning uses sound waves to produce tiny bubbles in a liquid, effectively dislodging contaminants from instruments. This method enhances the effectiveness of subsequent sterilization.

Comparative Overview: Traditional vs. Emerging Technologies

  • Speed and Efficiency: While traditional methods like steam sterilization are relatively fast, some emerging technologies offer quicker turnaround times. For instance, hydrogen peroxide gas plasma sterilization can be significantly faster than EtO sterilization.
  • Environmental Impact: Traditional methods, especially EtO, have been associated with environmental concerns due to toxic residues. Newer methods, like hydrogen peroxide gas plasma, are more environmentally friendly.
  • Instrument Longevity: Some traditional methods, like dry heat, can cause corrosion or reduce the lifespan of delicate instruments. In contrast, certain emerging technologies are gentler, ensuring prolonged instrument longevity.
  • Safety: While traditional methods are tried and tested, there’s always a potential risk, especially with methods like EtO, which is flammable. Emerging technologies often focus on reducing such inherent risks.

The Path Forward: Integrating Traditional and Emerging Technologies

The choice between traditional and emerging technologies isn’t binary. Instead, healthcare facilities can look to integrate both, selecting the most appropriate method based on instrument type, volume, and specific sterilization needs.

Moreover, ongoing training and education are paramount. As new technologies are adopted, sterile processing professionals must be well-versed in their operation, benefits, and limitations.


The realm of sterile processing is dynamic, with both traditional and emerging technologies offering unique advantages. By understanding the strengths and weaknesses of each method, healthcare institutions can make informed decisions, ensuring optimal patient safety and operational efficiency. As technological advancements continue to shape the industry, a blend of the old and the new is likely to define the future of sterile processing.
