1.3
Precautions
•
Failure to properly clean and high-level disinfect or sterilize
endoscopic equipment after each examination can
compromise patient safety. To minimize the risk of
transmitting diseases from one patient to another, after each
examination the endoscope must undergo thorough the
manual cleaning followed by high-level disinfection or
sterilization.
•
ALL channels of the endoscope MUST be cleaned and
high-level disinfected or sterilized during EVERY
reprocessing cycle, even if the channels were not used
during the previous patient procedure. Otherwise, insufficient
cleaning and disinfection or sterilization of the endoscope
may pose an infection control risk to the patient and/or
operators performing the next procedure with the endoscope.
•
If the endoscope is not cleaned meticulously, effective
disinfection or sterilization may not be possible. Clean the
