SMTL Dressings Datacard

Product Name: Contreet Non-Adhesive
Classification Name: Polyurethane Foam/Film dressing containing silver
Manufacturer: Coloplast



Contreet Non-Adhesive dressing consists of soft, absorbent polyurethane foam bonded to a semipermeable film that regulates moisture vapour loss, prevents strike through and acts as a bacterial barrier. A silver complex is dispersed homogeneously throughout the foam. In the presence of exudate, this complex provides sustained release of ionic silver to exert an antibacterial effect within the wound. Depending on the amount of exudate present, the dressing will continue to release ionic silver for up to seven days. The properties of the dressing are such that it maintains a bactericidal, warm, moist environment that facilitates healing.


Contreet Non-Adhesive dressing is indicated for the management of moderate to highly exuding wounds. These include venous leg ulcers, pressure ulcers, superficial burns, partial-thickness burns, donor sites, postoperative wounds, skin abrasions and diabetic ulcers, particularly those that are malodorous or failing to progress towards healing at the expected rate due to the presence of a significant bioburden. Contreet Non-Adhesive can be used on patients with wound infection at the discretion of the physician.


Contreet Non-Adhesive dressings are not recommended for use with hypochlorite solutions or hydrogen peroxide. They are also not recommended for use on exposed muscle or bone, and should not be applied to patients who are known to be sensitive to silver or any other ingredient of the dressing.

Method of use

If clinically indicated, the wound should be cleansed in accordance with normal practice.A dressing should be selected that provides a 1-2 cm overlap around the wound and applied with the plain (non printed side) in contact with the tissue. The dressing may be secured with tape or a bandage as required.

Frequency of Change

Contreet Non-Adhesive may be left in place for up to 7 days depending upon the production of exudate and the condition of the wound, but it should be changed when the exudate approaches the edge of the dressing from the dressing margin. Depending on the nature of the wound Contreet Non-Adhesive can be used throughout the healing process but for long-term use of silver containing products, a clinical assessment by a health care professional is recommended every 2 months. Diabetic ulcers, or wounds that are solely or mainly caused by an arterial insufficiency, should also be monitored frequently by a healthcare professional.


Contreet Non-Adhesive may cause a transient discolouration of the wound bed, which can be removed by gentle washing. Contreet Non-Adhesive should be removed prior to radiation therapy or procedures that include x-rays, ultrasonic treatment, diathermy, microwaves or MR scanning. In case of an allergic reaction, the manufacturer should be contacted for information on the identity of the components.


Contreet Non-Adhesive is presented individually wrapped in a peel pouch, sterilised by beta irradiation. The dressings are available in the form of square or round pads.
