moisture, nutrients (surfaces that are contaminated with organic matter), 98.6F (room temp), darkness, neutral pH (7), oxygen
reduces the number of microorganisms on an inanimate object to a safe/relatively safe level. Clean instruments with warm, soapy water w/ mechanical action to remove organic matter and other residue. Lowest Level.
Autoclave, gases (ethylene oxide), dry heat ovens, immersion in certain chemical agents. Destroys all forms of microorganisms, including spores or inanimate surfaces. Highest Level.
3 levels, highest level destroys most forms of microbial life except certain bacterial spores. Intermediate destroys many viruses, fungi and some bacteria including the one that causes TB. Middle Level
wash hands, use alcohol based hand scrub, wear clean/nonsterile examination gloves, change gloves between procedures, wear PPE to protect your eyes/nose/mouth/clothes, dispose of single use items, avoid 'sharps' injuries, do not manipulate used needles and use barrier devices
destroys microorganisms after they leave the body and prevents transmission of microbes from one person to another, hands and wrists washed for one to two minutes
destroys microorganisms before they enter the body/ prevents entry of microbes into the body during invasive procedures, hands and forearms washed 5-10 minutes w/ a brush
How does the autoclave work/sterilize?
cleans using steam and pressure, water above boiling, pressure all in inner chamber
applied to the outside of the material used to wrap instruments and indicates if the item has been exposed to steam
used to help properly sterilize and maintain sterilization
Autoclave Culture Strips
used to ensure that spores have been killed
Maintaining a sterile field
do not let sterile packages get damp or wet, always face the sterile field to ensure that the area has not been contaminated, hold all sterile items above waist level, place sterile items in the middle of the sterile field, 1 inch border is considered to be contaminated, do not spill any kinds of liquids onto the sterile field, do not cough/sneeze/talk over the sterile field, do not reach over the sterile field
have an opening to expose the operative site while covering adjacent areas
Phase 1 of Wound Healing
1-4 days, body increases circulation. Serum and RBC brought by extra blood form to close the wound and form a scab. Warmth, redness and pain signify the phase is working
Phase 2 of Wound Healing
several days to several weeks, scab from phase 1 continues to dry and pull the edges of the wound as closely together as possible
Phase 3 of Wound Healing
weeks to years, fibroblasts build scar tissue to guard the area
