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)
![Page 5: Surgical Aseptic Technique N001. See SLOs in Syllabus](https://reader033.vdocuments.site/reader033/viewer/2022061604/5517ca4d550346892b8b4ca8/html5/thumbnails/5.jpg)
Surgical Asepsis
Sterile technique “those practices that keep an area free of
all microorganisms” (Kozier) Including pathogens & spores
![Page 6: Surgical Aseptic Technique N001. See SLOs in Syllabus](https://reader033.vdocuments.site/reader033/viewer/2022061604/5517ca4d550346892b8b4ca8/html5/thumbnails/6.jpg)
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)

Principles of S.A.T.
The nurse must follow certain principles in order to maintain surgical asepsis
Failure to do could result in placing the client at risk for infection
These principles are same in all situations that requiring sterility. Injections, insertion of catheters etc.
![Page 11: Surgical Aseptic Technique N001. See SLOs in Syllabus](https://reader033.vdocuments.site/reader033/viewer/2022061604/5517ca4d550346892b8b4ca8/html5/thumbnails/11.jpg)
A Sterile Object Remains Sterile Only
When Touched by Another Sterile Object
Sterile touching sterile remains sterile Use of sterile gloves & sterile forceps Sterile touching clean becomes contaminated
![Page 12: Surgical Aseptic Technique N001. See SLOs in Syllabus](https://reader033.vdocuments.site/reader033/viewer/2022061604/5517ca4d550346892b8b4ca8/html5/thumbnails/12.jpg)
A Sterile Object Remains Sterile Only When Touched by Another Sterile Object
Sterile touching contaminated becomes contaminated
Sterile touching questionable is contaminated
When in doubt discard !

![Page 15: Surgical Aseptic Technique N001. See SLOs in Syllabus](https://reader033.vdocuments.site/reader033/viewer/2022061604/5517ca4d550346892b8b4ca8/html5/thumbnails/15.jpg)
A Sterile Object or Field Becomes Contaminated by Prolonged Exposure to Air Limit air currents Do not laugh, sneeze, or talk over a sterile
field- minimize movement around the sterile field
Reach around the sterile field When opening sterile equipment hold it as
close as possible without touching the field
![Page 16: Surgical Aseptic Technique N001. See SLOs in Syllabus](https://reader033.vdocuments.site/reader033/viewer/2022061604/5517ca4d550346892b8b4ca8/html5/thumbnails/16.jpg)
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
