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 manual

cleaning followed by high-level disinfection or sterilization.

•

ALL channels of the endoscope, including auxiliary water

channel where fitted, 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

endoscope and accessories thoroughly before disinfection or

sterilization to remove microorganisms or organic material

that could reduce the efficacy of disinfection or sterilization.

•

Olympus confirms validation of the endoscope reprocessors

recommended by Olympus only. If using endoscope

reprocessor that are not recommended by Olympus, the

endoscope reprocessor manufacturers are responsible for

validation of the endoscope reprocessor with the endoscope

models listed in its intended use statement. If using an

endoscope reprocessor, confirm that it is capable of

reprocessing endoscope including all channels. If there are

channels and/or other parts which cannot be cleaned and

high-level disinfected by the endoscope reprocessor, have to

undergo manual cleaning and high-level disinfection or

sterilization as described in Chapter 3, “Cleaning,

Disinfection and Sterilization Procedures” after using the

endoscope reprocessor. 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 you are

uncertain as to the ability of your endoscope reprocessor to

clean and high-level disinfect endoscope including all

channels, contact the endoscope reprocessor supplier for

specific instructions and/or connectors.

•

Patient debris and reprocessing chemicals are hazardous.

Wear personal protective equipment to guard against

dangerous chemicals and potentially infectious material.

During cleaning and disinfection or sterilization, wear

appropriate personal protective equipment, such as eye

wear, face mask, moisture-resistant clothing and

chemical-resistant gloves that fit properly and are long

enough so that your skin is not exposed. Always remove

contaminated personal protective equipment before leaving

the reprocessing area.

•

Thoroughly rinse off the disinfectant solution. Rinse the

external surfaces of the endoscope, channels and cleaning

equipment thoroughly with clean water to remove any

disinfectant solution residue.

•

The disinfection/sterilization room must be adequately

ventilated. Adequate ventilation protects against the buildup

of toxic chemical fumes.

•

Store alcohol in an air-tight container. Alcohol stored in an

open container is a fire hazard and will lose its efficacy due to

evaporation.

Chapter 2 Compatible Reprocessing Methods and Chemical Agents

Endo-therapy accessories which are marked by the words

“AUTOCLAVE” or “AUTOCLAVABLE”, or accessories with a

green model reference label, are compatible with

autoclaving.

2.2

Detergent solution

Use a medical-grade, low-foaming, neutral pH detergent or enzymatic detergent

and follow the manufacturer’s dilution and temperature recommendations.

Contact Olympus for the names of specific brands that have been tested for

compatibility with the endoscope. Do not reuse detergent solutions.

Excessive detergent foaming can prevent fluid from

adequately contacting internal lumens (e.g. channels).

2.3

Disinfectant solution

In the U.S., agents used to achieve high-level disinfection are defined as liquid

chemical germicides registered with the U.S. Food and Drug Administration as

“sterilant/disinfectants” which are used according to the time, temperature and

dilution recommended by the disinfectant manufacturer for achieving high-level

disinfection. These conditions usually coincide with those recommended by the

disinfectant manufacturer for 100% kill of mycobacterium tuberculosis.

In general, 2.0 – 3.5% glutaraldehyde solutions, when used according to the

manufacturer’s instructions for achieving high-level disinfection, are compatible

with Olympus endoscopes. Contact Olympus for the names of specific brands

that have been tested for compatibility with the endoscope.

If the disinfectant solution is reused, routinely check its efficacy with a test strip

recommended by the manufacturer. Do not use solutions beyond their expiration

date.

Alcohol is not a sterilant or high-level disinfectant.

2.4

Rinsing water

Once removed from disinfectant solution, the instrument must be thoroughly

rinsed with sterile water to remove any disinfectant residue. If sterile water is not

available, clean potable tap water or water which has been processed (e.g.

filtered) to improve its microbiological quality may be used.

When non-sterile water is used after disinfection, wipe the endoscope and flush

the channels with 70% ethyl or isopropyl alcohol, then air-dry all internal

channels to inhibit the growth of residual bacteria. Do not reuse rinsing water.

2.5

ETO gas sterilization

This instrument and other accessories listed as compatible with ethylene oxide

(ETO) gas sterilization in Table 2.1 can be sterilized by ETO gas and aerated

within the parameters given in Table 2.2. When performing sterilization, follow

the hospital’s protocol and the sterilization equipment manufacturer’s

instructions.

•

Before sterilization, the instrument must be thoroughly

cleaned and dried. Residual moisture inhibits sterilization.

•

The results of sterilization depend on various factors such as

how the sterilized instrument was packed or the positioning,

method of placing and loading of the instrument in the

sterilization device. Please verify the sterilization effects by

using biological or chemical indicators. Also follow the

guidelines for sterilization issued by medical administrative

authorities, public organizations or the infection management

sections at each medical facility, as well as the instruction

manual of the sterilization device.

•

All instruments must be properly aerated following ETO gas

sterilization to remove toxic ethylene oxide residuals.

•

Exceeding the recommended parameters may cause

equipment damage.

•

When reprocessing EVIS videoscope models, remove the

water-resistant cap before ETO gas sterilization (see Figures

2.1 and 2.2). When reprocessing OES fiberscope models,

install the ETO cap on the venting connector of the

endoscope’s light guide connector section before ETO gas

sterilization (see Figure 2.3). If ETO gas sterilization is

performed while the water-resistant cap is installed or the

ETO cap is not attached, air inside the endoscope will

expand and could rupture the covering of the bending

section.

•

Repeated ETO gas sterilization procedures will gradually

deteriorate the instrument. Do not perform ETO gas

sterilization to the instrument unnecessarily.

Steam sterilization (autoclaving) of accessories

The accessories listed as compatible with steam sterilization (autoclaving) in

Table 2.1 can be sterilized by steam within the parameters given in Table 2.3.

When steam sterilizing, follow the hospital’s protocol and the sterilization

equipment manufacturer’s instructions.

•

The results of sterilization depend on various factors such as

how the sterilized instrument was packed or the positioning,

method of placing and loading of the instrument in the

sterilization device. Please verify the sterilization effects by

using biological or chemical indicators. Also follow the

guidelines for sterilization issued by medical administrative

authorities, public organizations or the infection management

sections at each medical facility, as well as the instruction

manual of the sterilization device.

•

Exceeding the recommended parameters may cause

equipment damage.

•

Do not steam sterilize the endoscope. Steam sterilization

(autoclaving) will severely damage the endoscope.

•

Effective sterilization will not be possible if items are packed

tightly together in the autoclave; always pack items loosely.

•

Inspect each instrument package for openings, tears or other

damage. If an instrument package is opened or damaged,

seal the components in a new package and sterilize again.

•

Allow the packages to dry within the autoclave, using the

autoclave’s drying cycle (if available) or by opening the door

of the autoclave and allowing the packages to air-dry.

Handling a wet package can compromise its sterility.

•

Endo-therapy accessories and other items which are marked
