  Chapter 8

4
Objectives

• Define terms related to the terminal
  sterilization/disinfection process
• Identify the methods of processing items during
  terminal sterilization and/or disinfection
• Understand the process of instrument
  decontamination
• Understand Standard Precautions as they apply to
  decontamination

5
Decontamination

• Cleaning precedes all disinfection processes
• Cleaning is the physical removal of bioburden
  from instruments, furniture and equipment
• Purpose is to prevent cross-contamination between
  patients and between patients and personnel

6
Processing Area

• PPE
• Fully sort instruments
• Detachable parts are disassembled, keep together
• Sharps pointing down
• Heavy on bottom, delicate on top
• Separate if needed immediately
• Hinges open

7
Considerations

• Submersible/non-submersible
• Heat sensitive/non-heat-sensitive
• lumens

Cycle of Equipment Processing

• Point of use- the surgical procedure
• Transport to decontamination area
• Sort and disassemble
• Clean- manual or ultrasonic
• Decontamination- washer/decontaminator or
  washer/sterilizer
• Inspect
• Assemble and wrap
• Sterilize
• Storage
• Point of use

10
Manual Washing/Disinfection

• Detergents
• Neutral pH
• Slightly alkaline detergent when using automatic
  machines
• Low-sudsing detergents must be used in mechanical
  equipment to avoid damage to the equipment

11
Manual Cleaning

• PPE
• Three-sink arrangement
• 1st Sink- wash sink with water and detergent or
  disinfectant detergent solution
• 2nd Sink- intermediate rinse with distilled water
• 3rd Sink- final rinse with distilled water

12
Ultrasonic Cleaner

• Washer works by cavitation (sound waves)
• Cleans only, does not disinfect
• Removes bioburden from areas hard to reach by
  mechanical or manual cleaning
• Facility policy dictates the order of use for the
  Ultrasonic

13
Washer-Decontaminator

• Prerinse cycle
• Cleaning cycle
• Final rinse
• Dry phase
• At the conclusion of cycle, items are considered
  clean and have been exposed to an intermediate
  level of disinfection safe for handling

14
Washer-Sterilizer

• Follow manufacturers instructions
• Majority of stainless steel instruments and
  heat-tolerant items
• Gross bioburden must be removed prior to
  placement in WS
• Free-rinsing, low-sudsing detergent with a
  neutral pH should be used
• Do not mix metals

15
Washer/Sterilizer Cycles

• Prerinse
• Automatic detergent injection
• Fill phase
• Wash phase
• Postrinse
• Sterilization phase
• Lubrication
• Dry phase
• Items NOT ready for patient use
