Use of topical negative pressure with a lipidocolloid dressing: results of a clinical evaluation

To evaluate the protection and acceptability of Urgotul wound dressing in the local management of acute or chronic wounds receiving topical negative pressure (TNP) therapy.

This was a prospective multicentre non-comparative open-label trial. At each dressing change the investigating physician clinically evaluated and photographed the wound. Planimetric measurement was undertaken and wound depth was assessed at the start and end of the treatment. Follow-up was undertaken until deemed clinically unnecessary by the investigator.

Sixty-six patients were included (42 acute wounds and 24 chronic wounds) and followed up for an average of 17 days. Dressing changes were deemed entirely painless in 52% of cases (compared with 18% at baseline) and pain between two consecutive dressing changes was absent in 66% of cases (34% at baseline). Removal of the TNP-interface dressing combination was considered'very easy' or 'easy' in 94% of cases and adherence to the wound was recorded as 'absent' in 88%. On average, the dressings were changed every 3.8 +/- 1.1 days (all wounds were considered), and wound area and depth were reduced by 19% and 54% respectively by the end of the follow-up period.

Use of the interface dressing in combination with TNP substantially reduced the pain caused by dressing changes. It therefore makes more acceptable the use of this technique, which aims to optimise the management of wounds that are sometimes considered to be in a therapeutic impasse.
