Hygiene and Antisepsis

Why the formula 2% CHG + 70% IPA?

This formula is the only formula internationally recommended. According to the New England Journal of Medicine (2010), it reduces the incidence of surgical site infection by 41% compared to PVP.
This significant difference in efficacy is due to a superior residual effect along with the fact that PVP has a higher tendency to inactivate itself in the presence of organic matter. Other studies have shown that CHG is more effective in preventing bacteremia due to catheterization. It is also the only solution recommended by the WHO for antisepsis prior to blood sample collection.

Why is it recommendable to use a CHG solution with a concentration of 2% rather 0.5%?

As these concentrations suggest it, a 2% CHG solution is 4 times more powerful than a 0.5% CHG solution. As a result, one would need 4 layers of a 0.5% CHG in order to get the same antiseptic effect as a single layer of 2% CHG.
Moreover, due to is low concentration, 0.5% CHG solutions tend to inactivate themselves more easily in the presence of organic matter. Most guidelines recommend that the CHG solution used should have a concentration superior to 0.5%.

What are the advantages of Bactiseptic Orange’s tint?

– It enables a clear visualization of the disinfected area.
– Orange is a color that cannot be mistaken for any other skin condition.
– The tint is easily removed from skin, which allows for an effective post-operation wound observation.

What is the advantage of CHG solutions over PVP solutions?

According to the British Journal of Surgery, the preoperative skin antisepsis with CHG is superior to the PVP one for reducing surgical site infection in clean-contaminated surgery. Indeed, PVP has a higher tendency to inactivate itself in the presence of organic matter and because of CHG’s superior residual effect.

Why is Aquaseptic the best antiseptic available for Neonatology, Obstetrics and Gynecology?

1) PVP solutions are highly contraindicated for these specialties due to iodine absorption and its negative effects in children.
2) Alcohol is also contraindicated on sensitive skins. The use of a aqueous CHG solution is therefore the only appropriate option.
3) The 2% concentration of CHG is ideal (see above).
4) The product is available with or without its orange tint.


Surface disinfectants

What are the advantages of Kit Surfaces compared to other formats?

Unlike packages of pre-impregnated wipes, Kit Surfaces allows you to totally customize your disinfection of surfaces.
From a single Kit, you can choose the disinfectant, its concentration and the total impregnation volume per wipe, in order to optimize Kit Surface for your specific application. When circumstances will change, your customization will be very easily modified.

When should I use NDP Med Surfaces+?

NDP Med Surfaces+ is the ideal disinfectant for large critical and semi-critical surfaces such as operating theaters and ICU. It has an excellent cleaning action, and is effective in reduced times, which is essential for a disinfectant for surfaces. Its high concentration of active ingredients gives the product and broad spectrum of action.
The product’s ingredients allow it to be efficient even in the presence of organic load and contamination. NDP Med Surfaces+ isn’t only safe for the user; it also has a very high material compatibility, even though it is not recommend using it on transparent surfaces because the Iodine it contains could blur it.

If I first need to normally clean the place, why should I use Air Total+?

Air Total+ has a wider range of efficacy than most surface disinfectants, and most importantly, it reaches areas that are hardly reachable (or totally unreachable) through traditional cleaning and disinfection.

How exactly should I use Air Total+?

Place the bottle on an even surface and unseal. Press and rotate the discharge valve. The product forms a cloud in 1-3 minutes. Once the discharge is completed, leave for 1hour. Ventilate before entering the room. Apply in absence of people.


Instrument desinfection

Is NDP Med Foam compatible with every material?

The formulation in NDP Med Foam has been specifically tested for its compatibility with stainless steel, aluminium, polypropylene, polystyrene and silicone. After 24 hours of immersion, none of the materials suffered noticeable changes. Moreover, the formulation has been tested and used for years with a wide range of medical devices and no incompatibilities have been reported until now.

The application of NDP Med Foam on an ultrasound transducer is indeed really quick. How can I assure its efficacy in such short timing?

The microorganisms most transmitted through skin contact are Staphylococcus for bacteria and Candida for fungi. NDP Med Foam has been tested for its efficacy against both microbes according to the most stringent European Norms, EN 14561 and EN 14562 respectively, in times as short as 30 seconds: this is therefore the minimum contact time that has to be observed in order to guarantee the product’s efficacy.
