Study Notes
Microbiological Monitoring
- Microbiological monitoring in the IAP room is vital for maintaining sterile conditions and preventing infections.
- Monitoring involves placing contact or settle plates in pre-planned locations and sending them to the lab for analysis.
- The analysis compares results to baseline counts of microorganisms, which are pre-determined acceptable levels.
- The goal is for test results to be the same or better than the baseline.
- Microbiological monitoring also helps alert staff when environmental quality is slipping out of control, acting as an early warning system.
Staff Movement and Protective Clothing
- Staff movement between dirty and clean areas must go through a clothing change and hand-wash area.
- Protective clothing is worn by personnel entering the IAP room to reduce the risk of contamination to medical devices and the environment.
Manager Responsibilities and Dress Code
- Managers are responsible for providing protective clothing and ensuring it’s correctly used and disposed of.
- The dress code in the IAP zone dictates freshly laundered scrub suits.
- Scrub suits minimize bacterial shedding, provide comfort, maintain a professional appearance, and are changed daily or whenever soiled.
Standard and Tray Weight
- ANSI/AAMI ST77 and ST79 recommend a maximum weight of 25 pounds for surgical instrument trays.
- This weight limit includes the instruments and their containers.
Metal Basin Handling
- Ensure adequate drainage for metal basins during sterilization to prevent condensation.
- Use wicking material like surgical towels to facilitate drainage and drying, and maintain a 1-inch size difference between multiple basins.
The IAP Process
- The IAP process includes:
- Checking that the washer-disinfector cycle is successful.
- Removing the tray of devices from the washer carriage.
- Placing the tray on a clean workbench surface.
- Inspecting each device for cleanliness and functionality.
- Assembling the devices that were disassembled for washing.
- Laying out the tray in a manner that ensures good presentation and protection against damage.
Packaging Considerations
- The goal of packaging is to hold and protect devices for sterilization and maintain sterility.
- Key considerations include:
- The type of wrap used.
- The packaging techniques applied.
Types of Wrapping Techniques
- Sequential Wrapping: Two layers of wrap material are wrapped individually using a fold technique.
- Simultaneous Wrapping: Both layers of wrap material are wrapped together simultaneously.
- Square Fold Technique: The items are placed on the table parallel to the wrapper.
- Envelope Fold Technique: The items are placed on the table in a diamond shape to the wrapper.
- The square and envelope fold techniques can be used with sequential and simultaneous wrapping.
Rigid Containers
- Rigid reusable containers are becoming popular again, offering advantages like:
- Durability and sterility.
- User-friendliness with improved technology.
- Cost-effectiveness when used properly.
- Rigid containers are:
- Easily disassembled for cleaning, drying, and storage.
- Suitable for sterilization and cleaning methods.
- Compatible with cleaning agents.
- Suitable for storage configurations.
- Lockable, tamperproof, and non-resealable.
- Packed in a manner that allows for sterilizing agent penetration.
- Able to remove contents without contamination risk.
Rigid Container Checks Before Sterilization
- Filter and valve systems on rigid containers must be in proper working order before sterilization.
- Examine the filter plate for integrity before and after the sterilization process.
- Damaged or dislodged filters mean the contents are contaminated.
- Clean containers between each use and check the seal for damage.
- Containers require regular servicing by the manufacturer.
Disadvantages of Rigid Containers
- They present an ergonomics challenge due to their weight.
- They require additional storage space.
- They may necessitate longer cycle times to prevent wet packs.
- They entail extra cleaning effort.
- They pose a risk of filter dislodgement and instrument contamination.
Sealing Peel-Apart Pouches
- Sealing peel-apart pouches is crucial to maintain sterility after autoclaving.
Self-Sealing Pouches
- Self-sealing pouches have adhesive in the open end and require a heat sealing machine or autoclave tape to create a seal.
See-Through Peel Packaging Advantages
- See-through peel packaging is time-saving, fast, and easy to pack.
- It provides clear identification of the packed device(s) due to the transparent film.
Peel Pouch Use and Materials
- Peel pouches are used to pack small, lightweight, single instruments.
- They are made of medical-grade craft paper/plastic or spunbond polyolefin-plastic (Tyvek pouch).
Pouch Selection
- The choice of pouch depends on the sterilization method.
- Paper pouches are used for steam and ethylene oxide sterilization.
- Tyvek pouches are used for hydrogen peroxide sterilization.
Peel Pouch Availability and Packing
- Peel pouches are available in rolls or precut sizes.
- They can be heat sealed or have self-adhesive seals.
- Instruments are packed with the hinge open to ensure complete sterilant contact.
- Leave a 1/4-inch space around the package for air removal and sterilant penetration.
Air Removal
- Removing excessive air from the pouch before sealing is essential to prevent interference with sterilization.
