Policies and Procedures on Infection Control

7. Using a syringe, flush all channels with detergent which is diluted according to the
manufacturer’s instruction to remove the debris.
8. For endoscopes with elevators or auxiliary-water feeding, flush detergent solution
into elevator-wire channel/auxiliary-water channel.
9. Rinse all channels (including elevator-wire/auxiliary-water channels, if applicable)
and removable parts under running clean water thoroughly as to remove residual
debris and detergent.
10. Expel the water as much as possible by forced air through all channels.
11. Dry the exterior of the endoscope with gauze to prevent dilution of the liquid chemical.

Manual Disinfection
1. Immerse the endoscope in a basin of high-level disinfection (HLD), prepared according
the manufacturer’s instructions in term of dilution and temperature.

2. Using a syringe, irrigate all channels (including elevator-wire/auxiliary-water channels,
if applicable) with disinfection. For complete microbial destruction, make sure there
is no air pockets remain within the channels.
3. Soaked the endoscope in the HLD according to the disinfectant manufacturer’s
recommended time and temperature.
4. Flush each channel (including elevator-wire/auxiliary-water channels, if applicable)
with air before removing the endoscope from the HLD.

Rinsing After Manual Procedure
1. Rinse the endoscope internally and externally with clean water as to prevent exposure
and potential injury of skin/mucous membrane from chemical residue.
2. For endoscopes with elevators or auxiliary-water feeding, flush water into elevator-
wire channel/auxiliary-water channel.
3. Rinse all the removal parts of the endoscope with water.

Drying

1. Use syringe to inject air through air, water and suction channels, expelling the rinse
water.
2. For endoscopes with elevators or auxiliary-water feeding, inject air to flush water
from elevator-wire channel/auxiliary-water channel.

3. Flushed the channels (including auxiliary-water/elevator-wire channels, if applicable)
with 70-90% alcohol to assist in drying the interior channel surfaces.
4. Purge again all channels (including auxiliary-water/elevator-wire channels, if applicable)
with air. Air assists alcohol in evaporating any retained moisture.
5. Wipe the exterior surface of endoscope, eye, light guide connector, plugs and all
removal parts before connecting the endoscope to the light source.
6. The endoscope is ready to use after fitting back the valves and active air/suction
channels as well as the suction channel.
