Ch 8 (reprocessing) Flashcards
3 levels of disinfection?
-Low level
-High level
-Sterile
When would we use low level disinfection?
-Used to clean equipment in place
-Used for equipment that does NOT come into contact with mucous membranes/open wounds
-Used when there is no evidence of biological contamination on the equipment
What cleaning product do we use with low level disinfection?
Cavi-Wipe (or similar product)
When would we use high level disinfection?
-Used to clean equipment that HAS come into contact with mucous membranes, blood + bodily fluids
-Used to eliminate many or all pathologic organisms
What types of equipment would require high level disinfection?
-EV transducers
-Endocavitary probes
-Probes used during biopsies
Where do probes get cleaned with high level disinfection?
In a reprocessing room
(purpose built to ensure the cleanliness of the process)
What cleaning agents are used with high level disinfection?
Enzymatics, CIDEX, CIDEX OPA, Revital-OX, UV light
When would we use sterile disinfection?
-Used to clean reusable equipment that comes DIRECTLY into contact with mucous membranes, blood + bodily fluids
-Used to destroy all forms of microbial life
What types of equipment would require sterile disinfection?
In u/s department:
-Biopsy guns
-Metal biopsy trays
-Glassware
-Biopsy guides
What is the process of sterile disinfection?
Items are pre-washed with soap + water to remove gross solids before being placed in a bin to be picked up by the CPS/MDR staff
(central processing services/medical device reprocessing)
What is the low level disinfection process?
-Wipe off gel from probe
-Use cavi wipe to disinfect probe/machine + leave to air dry
-Ensure we wipe equipment within 5-10 mins of contact time to be fully effective
What happens if we use a wipe on equipment that is not an approved product?
We will VOID our warranty. The wipe can damage the equipment + u/s crystals
If there is blood or bodily fluids on our probe, what level of disinfection should we do?
High level
(can put any type of probe in the cleaning solution in the reprocessing room, not just EV)
If a probe has been covered with a probe cover, what level of disinfection should we do?
High level
What is the high level disinfection process?
-Wipe gel + blood off probe
-Scrub probe with an enzymatic sponge for 1-2 min in the dirty sink
-Rinse probe in dirty sink
-Dry probe with lint free cloth + place it into the cleaning solution/device (for 5-7 min)
-Rinse probe in clean sink + wipe with lint free cloth
-Place probe in plastic container or negative pressure storage (if available)
What must we check before we can place a probe into the cleaning solution?
-Test solution to ensure it is active
-Check temp to ensure it is warm enough
(some processes don’t require these steps)
How long should a probe soak in the cleaning solution?
5-7 mins
Equipment that requires sterilization will be processed where?
In a central reprocessing department of a hospital
3 sterile processes used?
-Autoclave (steam)
-Gas (ethylene oxide)
-Liquid chemicals
What type of process would be used for probes if they require sterile disinfection?
Gas or liquid chemicals used
(do not send a probe to the autoclave as they are sensitive to high heat!)
What must be done to the equipment before it can undergo the sterile disinfection process?
Equipment must have an enzymatic presoak/scrub to remove all biosolids prior to the sterilization procedure
4 steps in transporting clean probes?
-Wash hands + don gloves
-Clean probe removed from storage cabinet + placed in clean bin (with green cover over it)
-Probe now transported in the bin to the exam room
-Probe removed from bin + covered with probe cover to perform exam (for EV + biopsy procedures)
4 steps in transporting dirty probes?
-Remove probe cover + wipe gel off
-Place probe into bin + cover with red cover
-Transport bin to reprocessing room
-Place bin on dirty side next to dirty sink
What type of chemical disinfectant does camosun use?
Revital-Ox resert brand
