SMTL Dressings Datacard

Product Name: Unitulle
Classification Name: Dressing Paraffin Gauze BP (Light Loading)
Manufacturer: Hoechst Marion Roussel Ltd


Unitulle consists of a leno-weave fabric of cotton or cotton and viscose, which has been impregnated with white soft paraffin. The dressing is used as a primary wound contact layer and the paraffin is present to reduce the adherence of the product to the surface of a granulating wound. Two formulations of Paraffin Gauze Dressing are described in the British Pharmacopoeia: they differ in the weight of paraffin base present on the gauze. Unitulle, which is an example of a `light loading' product, contains between 90 and 130 grams of paraffin base per square metre of cloth. The alternative formulation bears a higher loading of paraffin, not less than 175 g/m (see Jelonet ).


Unitulle is used as a primary wound contact layer in the treatment of burns, ulcers, skin grafts (both donor and receptor sites), and a variety of traumatic injuries.


Although there are no absolute contra-indications to the use of Unitulle, if the dressing is placed upon a heavily exuding wound its semi-occlusive nature may cause tissue maceration by preventing the free movement of exudate away from the surface of the wound. This is less likely to occur than if a dressing bearing the higher loading of paraffin were to be used.

Method of use

Unitulle is applied directly to the surface of the wound and covered with an absorbent pad held in place with tape or a bandage, as appropriate.

Frequency of Change

The frequency of dressings changes will depend entirely upon the nature of the wound. If Paratulle is left in position for prolonged periods of time, it can become adherent and cause tissue damage upon removal.


Pack Shot Unitulle is presented individually wrapped in a paper/polyethylene peel pouch, sterilised by irradiation.


Paratulle should be stored in a cool place.
