Historical perspectives
Remember germs and how to combat
them was discovered in the mid 1800s
 Initially ill family members were cared for
at home
 Now ill members of society are cared for in
the hospital
 Chances of cross contamination are high

Application

Medical aseptic technique“Practices intended to confine a specific
microorganisms to a specific area
 Protective – reduces the numbers of
potentially infectious organisms
 Clean – absence of almost all microorganisms
 Dirty – soiled, denotes the likely presence of
microorganisms some of which could cause
an infection .”(Kozier)

Surgical Asepsis
Sterile technique
 “those practices that keep an area free of
all microorganisms” (Kozier)


Including pathogens & spores
Application of Surgical Asepsis
During procedures that require internal
perforation of a client's skin (IM or IV)
 When the skin’s integrity is broken
(surgical incisions or burns)
 During procedures that involve the
insertion of catheters or surgical
instruments into sterile body cavities
 (Potter & Perry 6thp. 802)

A Sterile Object Remains Sterile Only

sterile field
 Reach around the sterile field
 When opening sterile equipment hold it as
close as possible without touching the field

When a Sterile Surface Comes Into
Contact With a Wet, Contaminated
Surface, the Sterile Object or Field
Becomes Contaminated by Capillary
Action
Packages must be intact
 Note the water proof barriers
 Work on a dry surface

Fluids Flow in the Direction of
Gravity
Surgical hand scrub
 Hold forceps with tip down

Edges of the Sterile Field or
Container Are Considered
Contaminated
I inch all the way around
 Pour liquid off open bottle discard and
then pour the liquid

Opening Sterile Packages

Be sure and review
