Sterilization and Processing of Metal Basins

Processing Metal Basins

• When processing metal basins, ensure they are positioned to allow moisture to drain during sterilization to prevent water droplets from forming.
• Use wicking material, such as surgical towels, to facilitate drainage and drying.
• Maintain a 1-inch size difference between multiple basins to avoid condensation accumulation.

Packaging

• The purpose of packaging is to hold and protect devices during sterilization and maintain sterility.
• Key requirements for packaging materials include:
  • Providing an adequate barrier to microorganisms and particulates
  • Being suitable for the items being sterilized
  • Maintaining sterility of contents until opened
  • Allowing sterilants to penetrate and contact surfaces
  • Permitting removal of sterilants and aseptic delivery of contents
  • Protecting contents from physical damage
  • Ensuring complete and secure enclosure
  • Being resistant to tears, abrasions, and punctures
  • Ensuring tamper-proof sealing and air removal

Sterilization Flat Wrap

• Made of nonwoven Spunbond-meltblown-spunbond (SMS) fabrics and designed as a single-use product.
• Available in various sizes and weights.
• Wrapping techniques include:
  • Sequential Wrapping: two layers of wrap material wrapped individually using a fold technique
  • Simultaneous Wrapping: both layers of wrap material wrapped together simultaneously

Folding Techniques

• Square Fold Technique: used for heavier items
• Envelope Fold Technique: used for smaller items

Containers

• Rigid reusable containers are making a comeback due to improved technology and cost-effectiveness.
• Key considerations for using containers include:
  • Easy disassembly for cleaning, drying, and storage
  • Compatibility with sterilization and cleaning methods
  • Lockable, tamperproof, and non-resealable
  • Packed to allow penetration of sterilizing agents
  • Ability to remove contents without contamination
• Filter and/or valve systems must be secure and in proper working order before sterilization.
• Disadvantages of using containers include:
  • Ergonomic challenges due to heaviness
  • Additional space required for storage
  • Longer cycle time required
  • Extra effort for cleaning and maintenance
  • Potential risk of filter dislodge leading to instrument contamination

Pouches and Reels

• Various packaging materials available for individual surgical instruments.
• Peel-apart pouches with a see-through front and paper backing are often used for single devices or small loads.
• Sealing peel-apart pouches is essential to ensure sterility after autoclaving.
• Self-sealing pouches have adhesive manufactured into the open end and require a heat sealing machine or autoclave tape to create a seal.
• The see-through peel packaging is a time-saving concept.
