Cleaning and disinfection
SOPRO does not recommend the use of Cidex
temperature for periods of 28 days for manual high-level disinfection, because such solutions
and agents contain high concentrations of surfactants, which may dry and crystallise on devices
if they are not carefully rinsed off. Solutions containing glutaraldehyde at a concentration of
more than 2.4% must be avoided, because a higher percentage of glutaraldehyde may damage
devices.
The user should be adequately trained in the decontamination and disinfection of semi-critical
medical devices and the handling of liquid chemical germicides.
Read the instructions for use provided by the manufacturer of the disinfectant for more detailed
information about the use of the disinfectant solution, particularly appropriate rinsing techniques.
6.3.2 Materials and conditions
• 0.55% ortho-phthalaldehyde (e.g. Cidex OPA) high disinfectant solution
• temperature: 20 °C ± 2 °C (60 °F ± 3 °F)
• sterile water
• protective gloves, eye protection, fluid-resistant gowns and a mask
6.3.3 Steps to follow
1. Place the devices in approved plastic containers. Do not soak the devices with other
instruments to prevent any potential damage.
2. Prepare the disinfectant solution for use. No activation is required. Use (Cidex) activated
dialdehyde solution test strips to check that the solution is above the minimum effective
concentration. Test the solution prior to every use. Note the date on which the solution was
poured into the original container.
3. Fully immerse the device in the Cidex OPA solution for about 5 minutes, for no longer than 1
hour.
You must take care to eliminate all air bubbles adhering to the surface of the immersed
device.
4.Once disinfection is complete, remove the devices from the disinfectant solution and rinse
them, immersing them completely in a large quantity of sterile water (e.g. 8 litres).
Keep the devices fully immersed for at least 1 minute.
5. Rinse with a minimum 500 ml of water through all openings during each individual rinse.
Repeat this procedure for a total 3 rinses by immersion. Dispose of the water between each
rinse, as it will have been contaminated with disinfectant. Use fresh sterile water for each
rinse by immersion. Meticulous rinsing of the devices is essential to prevent the toxic effects
of any residual disinfectant solution.
Incomplete rinsing can seriously hamper light transmission.
