Manual Cleaning…Is it really that important?
SGNA states, “Manual cleaning of endoscopes is necessary prior to
automated or manual disinfection. This is the most important step in
removing the microbial burden from an endoscope.” (SGNA, Standards of Infection
Control in Reprocessing of Flexible Gastrointestinal Endoscopes , 2012., 14)
Manual cleaning:
-Reduces the number of microorganisms and organic load on an endoscope
(bioburden).
• Reduces the potential of biofilm growth.
• Biofilms consist of colonies of organisms that form
structures with potential to have maximum growth.
• Biofilms adhere to the internal channels of endoscopes.
• This growth potential is an important factor because they
interfere with disinfection.
-Reduces the burden on the high-level disinfectant.
(i.e. Rapicide or Rapicide PA)
- Starts at the bedside, immediately after withdrawal.
Step 1 – Pre-cleaning at Bedside
1) Immediately – Wipe down scope’s
exterior with a detergent-soaked cloth
like Intercept or with an Intercept Wipe.
**Detergent solution should be diluted
per manufacturer’s label. **
Intercept Solution Dilution
1 oz = 1 full pump per 3 gallons of water
Step 1 – Pre-cleaning at Bedside continued…
2) Suction detergent through the
scope, then air. Alternate suctioning
of air and detergent to create
agitation.
3) If applicable, install the air/water
cleaning adapter. Flush with water,
then air, through air/water channel.
4) Clear the air and water channels
according to the manufacturer’s
instructions.
2
Step 1 – Pre-cleaning at Bedside continued…
5) Flush detergent, then air
through ANY SPECIAL FEATURE
CHANNELS, such as auxiliary
water inlet , elevator wire
channel, etc.
6) Detach all removable parts
and cleaning equipment and
place in accessory bag.
Step 1 – Pre-cleaning at Bedside continued…
7) Ensure water-resistant cap (soaking
cap) is attached, if applicable.
Step 2
Transport Enclosed Contaminated Scope to Reprocessing Area
Contain the scope and transport
to reprocessing area.
3
Step 3 – Leak Testing
Purpose: To detect a hole or leak in an endoscope.
Why leak test?
1) To prevent cross contamination of patient matter or chemicals.
2) To prevent fluid invasion.
3) To prevent very costly & lengthy repair.
Always:
- Leak test after EVERY procedure and PRIOR to immersing the endoscope
in any fluid.
- Test for leaks according to the endoscope manufacturers’ instructions.
Step 3 – Leak Testing continued…
Leak test methods can be WET, DRY or AUTOMATIC
DRY LEAK TEST
•Attach leak tester to scope.
•Squeeze bulb to level of desired pressurization.
•Confirm bending section has inflated slightly.
•Observe the gauge continuously for 90 seconds.
•While observing the gauge, angulate the scope fully in each direction
at least once.
•A steady drop in pressure on the gauge indicates a leak.
•If this fails, check integrity of water resistant cap connection and reconnect, if necessary.
4
Step 3 – Leak Testing continued…
WET LEAK TEST
•Remove all valves and/or buttons from the endoscope.
•Turn on air supply (i.e. maintenance unit or light source).
•Depress pin in leak tester connector to ensure all is flowing through tubing.
•Attach the leak tester connection to the scope.
•Confirm bending section has inflated slightly.
•Carefully place the scope in a basin of water full enough to completely cover the scope,
ensuring the knobs are covered.
•Observe the scope for at least 90 seconds.
•Angulate the scope fully in each direction at least once during the observation period.
•Depress each of the switches to observe for leaks.
•If testing a duodenoscope, activate the elevator wire both up and down as well.
•A steady stream of bubbles indicates a leak. If a leak is found, keep scope on leak tester
and finish manual cleaning.
•Bubbles escaping at an irregular rate usually indicates trapped air.
•If no leak found, remove the scope from the basin.
•Turn off the air supply.
•Unplug the leak tester from the air supply, and release all of the air pressure in the scope.
•Remove the leak test connector from the scope.
Step 3 – Leak Testing continued…
VERISCAN LT AUTOMATIC LEAK TEST
The Veriscan LT features:
•Detect leaks with 99% accuracy.
•Lowers cross-contamination risk due to undetected leaks.
•Detects endoscope leaks early when repairs are minor and
less costly.
•Unsurpassed leak detection compared to visual observation
methods.
•Dry endoscope leak test – no fluid submersion required.
•Utilizes highly sensitive, innovative leak sensing technology.
•Compatible will all flexible endoscopes.
•Simple to operate.
•Ensures compliance with endoscope leak test protocols.
•Provides consistent, repeatable endoscope leak testing.
•Printed confirmation of leak test results.
•Computerized endoscope leak test records and reports.
Step 3 – Leak Testing continued…
- If a leak is found, the endoscope needs to be taken out of service and
sent for repairs. Follow the manufacturer’s instructions for
decontamination to avoid further damage.
- For smaller leaks, the Medivators Advantage and DSD-LT reprocessors
can be used to reprocess the endoscope prior to being sent for repair by
keeping the scope pressurized with air for the entire reprocessing cycle to
avoid fluid invasion.
- Contaminated scopes should never be placed in a suitcase and sent off
for repair.
5
Step 4 – Manual Cleaning
BRUSH then FLUSH
BRUSH…
-
Scrub, brush, and soak scope and all removable parts.
Ensure the correct brush size is being used.
Do not reuse single-use brushes.
Valves also should be depressed and the exposed areas brushed.
Immerse scope in freshly prepared detergent solution like Intercept.
Thoroughly clean exterior of endoscope.
Brush distal tip and elevator, if applicable.
Brush the entire suction/biopsy channel system.
- Clean brush each time it exits distal tip
and umbilical cord.
- Brushing should be repeated until
no debris is visible on the brush.
Step 4 – Manual Cleaning
BRUSH then FLUSH
FLUSH…either manually or with SCOPE BUDDY,
an Endoscope Flushing Aid.
Flush:
1st) with detergent
2nd) purge with air
3rd) with clean water
4th) purge with air
Step 4 – Manual Cleaning
Flush all channels with Detergent, followed by an air purge:
1. Attach cleaning adapters or Scope Buddy connectors and
channel plugs to endoscope.
2. For manual flushing, push the required amount of Intercept
Detergent solution through all channels (suction, air/water,
accessory water, elevator wire).
3. For Scope Buddy flushing, push the START button.
4. Remove filter from detergent solution and flush air
through all channels to purge detergent from channels.
6
Step 5 – Rinsing with Water; Purging with Air
FLUSH…all channels with clean water; then purge with air.
-The scope’s exterior and removable parts need to be rinsed thoroughly
under water to remove residual detergent.
- All internal channels need to be flushed with water.
- This can be accomplished with SCOPE BUDDY by placing the intake filter
in clean water and pressing START.
- If no SCOPE BUDDY, then manual flushing
of all channels with clean water needs to be done
(including auxiliary-water/elevator-wire, if applicable).
-Remove water from all channels by purging with air.
-Use a soft, lint-free cloth to remove excess moisture
from the exterior of endoscope and cleaning accessories
in reparation for disinfection.
Step 6 – High Level Disinfection
