Quick Reference
Asepsis: Practices used to prevent contamination by microorganisms.
Medical Asepsis (Clean Technique)
Reduces the number and spread of microorganisms.
- Perform hand hygiene.
- Use appropriate PPE.
- Clean and disinfect equipment and surfaces.
- Handle soiled linens and waste safely.
- Avoid cross-contamination between clean and dirty items.
Surgical Asepsis (Sterile Technique)
Prevents microorganisms from contaminating a sterile field or sterile equipment.
- Use sterile instruments and supplies.
- Maintain sterile barriers and fields.
- Prevent contamination during sterile procedures.
- Replace supplies if sterility is compromised.
Important Considerations
- Clean does not mean sterile.
- Disinfection reduces or inactivates many pathogens; sterilization destroys all forms of microbial life, including bacterial spores.
- Sterile procedures require specific training and authorized responsibilities.
- CNAs primarily use medical asepsis during routine patient care.
- Follow facility policies for contaminated equipment, specimens, and spills.
