3Historical perspectives Remember germs and how to combat them was discovered in the mid 1800sInitially ill family members were cared for at homeNow ill members of society are cared for in the hospitalChances of cross contamination are high
4Application Medical aseptic technique- “Practices intended to confine a specific microorganisms to a specific areaProtective – reduces the numbers of potentially infectious organismsClean – absence of almost all microorganismsDirty – soiled, denotes the likely presence of microorganisms some of which could cause an infection .”(Kozier)
5Surgical Asepsis Sterile technique “those practices that keep an area free of all microorganisms” (Kozier)Including pathogens & spores
6Application 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)
10Principles of S.A.T.The nurse must follow certain principles in order to maintain surgical asepsisFailure to do could result in placing the client at risk for infectionThese principles are same in all situations that requiring sterility.Injections, insertion of catheters etc.
11A Sterile Object Remains Sterile Only When Touched by Another Sterile Object Sterile touching sterile remains sterileUse of sterile gloves & sterile forcepsSterile touching clean becomes contaminated
12A Sterile Object Remains Sterile Only When Touched by Another Sterile Object Sterile touching contaminated becomes contaminatedSterile touching questionable is contaminatedWhen in doubt discard !

16When a Sterile Surface Comes Into Contact With a Wet, Contaminated Surface, the Sterile Object or Field Becomes Contaminated by Capillary ActionPackages must be intactNote the water proof barriersWork on a dry surface
17Fluids Flow in the Direction of Gravity Surgical hand scrubHold forceps with tip down
18Edges of the Sterile Field or Container Are Considered Contaminated I inch all the way aroundPour liquid off open bottle discard and then pour the liquid
