Sanitization: fancy word for CleaningRemoving of foreign material
Dirt, body fluids, lubricants
Using detergents, soap & H2O, scrubbing, ultrasonic
1st step in the disinfection and/or sterilization process
Temperature of the water is important.

UltrasonicBath of special solution through which sound
waves pass loosing debris from instrumentsUsed for sanitization of
Sharp objects: scalpels, or those with sharp edges
Be aware that instruments made of different metals should be separated
Always place instruments in open position

NoteFor instruments contaminated with blood or
protein these need to be rinsed in cool water to remove contamination before sanitization
This step is not necessary if usingSpecialized detergents that are neutral ph,
low sudsing, formulated to dissolve blood and blood products

After CleaningRinse individuallyPlace on clean towelDry thoroughlyInspect for damage and smooth operationIf instruments do not require further
disinfection or sterilization they can be stored

Disinfection: Second LevelProcess that eliminates many or all
microorganisms except sporesEither with liquid chemicals or boiling
(instruments placed into room temperature water that is raised to boiling for a period of time and then allowed to cool)

Sterilization: Third StageRequired for all instruments or supplies that
will penetrate a client’s skin or come in contact in areas below the integumentary level.
Any instrument that will come in contact with a sterile field

AutoclavePrimary method of
sterilizing instrumentsSteam operate at lower
temperature Moist steam permeates
the wrapping Moisture causes
coagulation of proteins causing cells to burst and killing them.

Microorganisms
Other Methods of SterilizationChemical – using chemicals
solutions (Chemiclave) when heat can’t be used
Dry heat – used when can’t use moist heat or chemicals
Gas – used in hospitals takes longer than steam
Microwave – low pressure steam with radiation to produce localized heat that kills microorganisms.

Apply Your KnowledgeWhat is the difference between sanitization and sterilization?
Sanitization is the cleaning and scrubbing instruments and equipment to remove contaminated materials and microorganisms.
Sterilization is the complete destruction of all microorganisms -pathogenic, beneficial, and harmless - from the surface of instruments and equipment.
