FLEXIBLE ENDOSCOPES
For the cleaning of flexible endoscopes – consult manufacturer’s instructions, AS/NZ 4187 and GENCA Guidelines. The is also a Queensland Health web site on Endoscopic Reprocessing which is interactive.
Endoscopes should be cleaned as soon as possible so that secretions do not dry and harden which makes cleaning much harder.
Manufacturer’s instructions should always be followed as well and AS/NZ 4187.
Staff should be familiar with the structure of the endoscope and be trained in cleaning techniques and practices.
