Study Notes
Infection Control and Sterilization
- The Spalding classification system categorizes patient care items into critical, semi-critical, and non-critical based on infection risk.
- Critical items must be sterilized before use, as they penetrate skin or mucous membranes.
- Semi-critical items require high-level disinfection to ensure safety after coming into contact with mucous membranes or non-intact skin.
- Non-critical items are disinfected at a low level since they do not enter sterile areas but may have contact with skin.
Disinfection Methods
- Pasteurizers utilize heated water for disinfection.
- Phenolics are categorized as intermediate to low-level disinfectants.
- Alcohol requires 5 to 10 minutes of wet contact for effective disinfection.
Instrument Handling and Testing
- High-level disinfectants include glutaraldehyde and ortho-phthalaldehyde.
- Electronic testing for laparoscopic insulation should take place in the clean assembly area before assembly.
- Scissors over 4 inches in length should be tested with red material for functionality.
Cleaning and Maintenance
- Arthroscopic instruments are primarily used in joint surgeries and require specific cleaning protocols.
- Robotic instruments cannot be disassembled for cleaning, contain mechanical components, and are heavier than standard instruments.
Surgical Instrument Characteristics
- Hemostats have a box lock mechanism that locks and holds them in position.
- Ratchets are the pivot points where two parts of a ring-handled instrument meet.
- Scissors are surgical instruments intended for cutting or dissecting tissue, while forceps are used for grasping.
Sterilization and Safety Practices
- Passivation is a process that builds a protective chromium layer on instruments during manufacturing.
- Instrument lubrication must align with the manufacturer's instructions to ensure proper care.
- The humidity level for sterilization preparation and packaging should be maintained between 30% and 60%.
Disinfection Terminology
- Disinfectants kill most pathogenic organisms but do not eliminate spores.
- Anti-septics are used on living tissues to slow down microbial growth.
- Thermal disinfection effectively kills microorganisms, except spores.
Practical Applications
- Clean multi-part instruments must be disassembled and sterilized following the manufacturer's guidelines.
- Implants and surgical instruments fall under the critical items category, necessitating rigorous sterilization protocols.
- Table tops and similar surfaces are classified as non-critical items, requiring routine disinfection.
Medical Device Classification
- Sterilization packaging is categorized as Class 2 medical devices within regulatory frameworks.
- Envelope fold is the predominant wrapping technique used for small packs in most surgical trays.
