Definitions
Sterilization
The act or process, physical or chemical, which
destroys or eliminates all
forms of life, especially microorganisms and their spores.
Disinfection
The use of a chemical procedure that eliminates
virtually all recognized pathogenic
microorganisms but not necessarily all microbial forms (i.e.,
bacterial spores) on inanimate objects.
Sanitation
A chemical process that reduces the number of
bacterial contaminants to
safe levels as judged by
public health requirements. Sanitation
does not eradicate. The term is commonly used for substances
applied to inanimate objects.
Antisepsis
A substance that prevents or arrests the growth or
action of microorganisms
either by inhibiting their
activity or by destroying them.
Usually applies to preparations applied to living tissue.
In
order to determine what items in an electrologist’s treatment
room should be sterilized, disinfected
or sanitized, we need to
first classify these items as Critical,
Semi-Critical or Non-Critical.
Critical Item
Instruments or objects that come in direct contact
with the bloodstream or
other normally sterile areas
of the body. Critical items require
sterilization before use.
Semi-Critical Item
Instruments that may come in contact with mucous
membranes and non-intact
skin, but do not ordinarily
penetrate body surfaces. Semi-critical
items require high-level disinfection or sterilization.
Non-Critical Item
Items that will come into direct contact with the
client, but only with intact
skin. Depending on the
particular item and nature of contamination
during use, simple washing or scrubbing with a detergent
and warm
water may be adequate or chemical disinfection with an
intermediate or low level disinfectant
may give added assurance.
