Telfa consists of a thin layer of absorbent cotton fibres, enclosed in a sleeve of poly(ethylene terephthalate) that is perforated in a regular pattern and sealed along two edges. The plastic film is present to prevent the dressing adhering to the surface of the wound, and is perforated to allow the passage of exudate from the wound into the body of the pad.
Telfa may be used on its own to dress dry sutured wounds, superficial cuts and abrasions, and other lightly exuding wounds. It may also be used as the primary wound contact layer for more heavily exuding wounds, if backed by a second absorbent dressing.
In common with other perforated plastic film dressings, Telfa should be used with caution in the treatment of leg ulcers that produce copious quantities of very viscous exudate. Under these circumstances, the exudate may become trapped under the dressing, leading to maceration and inflammation of the surrounding skin.
Method of use
Telfa has a low absorbent capacity and is therefore intended for use on lightly exuding wounds. Under these circumstances, a single dressing may simply be secured in position with surgical tape. On more heavily exuding wounds, Telfa may be used as a wound contact layer, beneath a secondary absorbent pad held in position with tape or a bandage.
Frequency of Change
The frequency with which the dressing should be changed depends entirely upon the nature and condition of the wound.
