Cleaning Flashcards
(25 cards)
Critical
Anything used to cut open the skin
Semi critical
anything that comes in contact with mucosal tissue
Non critical
anything on the outside of the body
Pre cleaning
Flushing and wiping down the scope as soon as the procedure is done to prevent the start of biofilm
Transport
Transport the scope to the reprocessing room with a hard scope transport system or other acceptable containers usually with a disposable lining such as a “Cinch” system to cover the scope
reprocessing room
Clean and dirty areas
Dirty- where the manual cleaning happens
Clean- high level disinfection
Enzymatic Detergent and sponge
used to wipe down the scope
Brushes
dual or single ended brushes
techs make sure that all channels and ports are throughly brushed through until there is no soil visible on the bristles
Visual inspection
happens after the manual cleaning
at a minimum the scope must be inspected by the naked eye
also can use a borescope which is a scope where you “scope the scope” and check for retained debris and damages
Leak tester
leak testing should be performed right after pre clean and before manual clean
mechanical flushing system
used to flush the inside of the endoscope with enzymatic detergent or water
Automated endoscope reprocessor (AER)
25-35 minute process to perform high level disinfection
high level disinfection chemistries
glutaraldehyde, peracetic acid and orthopthalalde hyde (OPA)
drying
After HLD (high level disinfection) outside of the endoscope is dried using a dry cloth
internal channels are dried using pressurized intstrument grade air
Endoscope must be bone dry to prevent biofilm
supplemental measures
Repeat HLD
Liquid chemical sterilization (LCS) reprocessing system can be used to destroy all life forms of microbial life
Ethylene Oxide Gas (EtO)
storage room
scopes must be dry and stay dry
must be hung vertical so that no fluid collects in the scope and shouldnt touch other scopes or floors or walls to prevent damage
cabinet should be closed to prevent contamination from dust and microbes
Biofilm
community of microorganisms with a layer of protection
pathogens
microorganisms that cause infection
ingredients for biofilm development
nutrients, water, a surface, bacteria
3 stages of biofilm
attachment, growth, detachment
protective layer of biofilm
slimy forcefield
EPS
extra polymeric substance
MRDO or superbugs
resistant to multiple anti biotics
CRE (carbapenem-resistant enterobacteriaceae)
MDROS
sometimes fatal
difficult to treat
