Product Name: Cutinova Hydro
Classification Name: Polyurethane dressing with superabsorbent
Manufacturer: Smith & Nephew Healthcare Ltd



Cutinova Hydro is an absorbent self-adhesive wafer containing a polyacrylate superabsorbent.

The dressing, which is about 2 mm thick, consists of a hydrophilic polyurethane matrix containing particles of polyacrylate, bonded to a semipermeable polyurethane membrane that acts as a carrier and provides a bacterial barrier.

Exudate is taken up by the superabsorbent particles to form a gel, which is not released from the dressing but retained within its structure, leaving no residue upon the wound surface following removal of the dressing. The superabsorbent preferentially absorbs the aqueous component of exudate, effectively increasing the concentration of enzymes, growth factors and other proteins in the exudate that remains within the wound.

Cutinova Hydro swells as it absorbs liquid; eventually taking up the contours of the wound and the affinity of the superabsorbent for water is such that it is retained by the dressing even when subjected to pressure.


Cutinova Hydro is indicated for use on most types of exuding wounds, but is most suited to low-to-moderately exuding wounds. It can be used on leg ulcers, pressure sores, diabetic foot ulcers and superficial and partial thickness burns.


Cutinova Hydro is contra-indicated for full thickness wounds with exposed muscle, bone or tendon or dry wounds such as those covered with black necrotic eschar. The dressing should also not be applied to wounds surrounded by fragile skin.

Method of use

Wherever possible a dressing should be selected that is large enough to ensure that it overlaps the wound edges by approximately 2 cm. Prior to application, the backing paper is removed and the dressing is rolled over the wound and gently pressed into position. Should the wound be larger than a single dressing, two or more dressings can be applied ensuring a minimum overlap of 2 cm.

Because of the tacky nature of the edges of the Cutinova Hydro a suitable secondary dressing may be required to prevent it from sticking to clothing or bedding.

Frequency of Change

The frequency of dressing changes depends upon the condition of the wound and the amount of exudate produced. During the initial cleaning phase the dressing may require changing every 1-3 days but subsequently the intervals between changes can be extended to up to 7 days. The formation of a pronounced white blister or bubble, visible through the back of the dressing, indicates that it needs replacing.


Cutinova Hydro should not be used with solutions of hypochlorites or peroxides as these will chemically degrade the product.


Cutinova Hydro is presented in a paper peel pouch, sterilised by gamma irradiation.
