Study Notes
Cleaning and Decontamination Terms
- Cleaning: Involves removing all visible and non-visible soil from medical devices.
- Decontamination Area: A specified location for collecting and cleaning soiled items within a healthcare facility.
- Relative Humidity: The percentage of water vapor in the atmosphere compared to its total capacity without condensation.
- Biohazardous Waste: Waste containing infectious agents that risk human health.
- Deionized Water: Water cleaned of all minerals through an ion exchange process.
- Distilled Water: Water gained through boiling and condensing steam, removing impurities.
- Reverse Osmosis: Water purification process that removes impurities by forcing water through a semipermeable membrane.
- Pyrogen: Substances that induce fever when introduced to the blood.
- Cavitation: A cleaning method where low-pressure bubbles burst to dislodge soil from instruments.
- Impingement: A cleaning method using pressurized water spray to remove bioburden.
Cleaning Agents and Techniques
- Emulsifier: Ingredients that combine substances like oil and water, aiding cleaning.
- Surfactant: Lowers water surface tension, enhancing the solubility of organic compounds.
- Chelating Agents: Chemicals that prevent hard water minerals from impairing soap or detergent efficacy.
- Toxic Anterior Segment Syndrome (TASS): Inflammatory reaction caused by noninfectious substances damaging intraocular tissues.
Decontamination Procedures
- Horizontal surfaces in the decontamination area must be cleaned daily, ideally at shift changes.
- Instruments should be rinsed with cool water to prevent protein coagulation before cleaning.
- Powered surgical instruments must not be immersed.
- The optimal temperature for the decontamination area is 60-65°F; humidity levels should be 30%-60%.
- Decontamination cleaning procedures include prompt cleaning of spills, daily floor cleaning, and frequent biohazard waste removal.
Mechanical Cleaning Devices
- Ultrasonic Cleaners: Utilize cavitation for detailed cleaning, effective in removing debris from difficult areas.
- Washer-disinfectors: Use a three-step process including pre-rinse, detergent wash, and final rinse using high-temperature water.
- Automated Endoscope Reprocessors (AERs): Must clean items prior to processing, utilizing specific approved cleaning chemicals.
Enzymatic Cleaners
- Lipase Enzymes: Target fatty material such as bone marrow for breakdown.
- Protease Enzymes: Attack proteins found in blood and tissue remnants.
- Amylase Enzymes: Responsible for breaking down starch.
Instrument Cleaning Practices
- Three-Sink Arrangement: For manual cleaning, includes a wash sink with detergent, an intermediate rinse sink with plain water, and a final rinse sink with deionized water.
- Use low-foaming detergents in ultrasonic cleaners to maintain cleaning efficacy.
- Avoid abrasive cleaners and substances like saline or hydrogen peroxide, unless recommended by device manufacturers.
Safety and Protocols
- Emergency Eyewash Stations: Should be reachable within 10 seconds or 30 meters from chemical exposure areas.
- Cleaning tools for the decontamination area must not be used elsewhere to maintain cleanliness.
- New staff in the decontamination area require thorough orientation about safety and procedures.
Miscellaneous Facts
- Compressed air used for medical devices must be free from contaminants such as oil and water.
- Proper preparation and constant maintenance of a clean work area are critical for effective decontamination.
