An evaluation of a non-adhesive hydropolymer* foam dressing and silicone border hydropolymer* dressing on patients with differing wound aetiologies


Introduction: The primary aim was to evaluate a non-adhesive hydropolymer foam dressing and a silicone border hydroploymer dressing with LiquaLock® Advanced Absorption Technology on patients with low to highly exuding wounds. The secondary aim was to review the conformability of this cuttable non-adhesive foam dressing on patients with fragile skin integrity surrounding the wound edge.


Method: Patients recruited into the case series evaluation had wounds of varying aetiology which presented predominantly with low to moderate exudate levels and had no clinical features of infection. They were considered suitable for the application of a non-adhesive foam dressing over any adhesive foam backed dressing due to the fragile integrity of the surrounding skin. Patients were reviewed over a four week period where standard care was provided and objective measures, including wound tracings and photographs, were performed once a week.

Results & Discussion:  Ten patients with wounds of various aetiologies were recruited according to the criteria. There was a serial decrease in wound size over the four week evaluation period. Two patients achieved complete re-epithelialisation between baseline and endpoint. A significant reduction in over-granulation was observed in all cases. Furthermore the dressings demonstrated good conformability on a range of anatomical sites which are often considered challenging to dress with other products.  Dressing absorption was retained over a seven day period in low exuding wounds and wounds with moderate exudate levels often required dressing changes every three days. This suggests that the non-adhesive polymer dressing may be suitable for treatment of venous leg ulceration in conjunction with compression bandage systems given that no episodes of wound related infections were experienced and patients did not report any increase in pain over the case series evaluation period. The silicone border hydroploymer is suitable for patients with fragile skin as no patients experienced any complications with the surrounding skin.

Conclusion: The preliminary findings from this case series evaluation suggest that the wound healing potential may be accelerated with the use of both the non-adhesive and the silicone border hydropolymer foam dressing with LiquaLock® Advanced Absorption Technology. The dressings were conformable and retained low to moderate exudate levels over a maximum of seven days which suggests a substantial economic gain in reducing the frequency of redressing visits. One interesting finding was the significant reduction in over-granulation tissue that was observed in all cases. The reason for this is unclear but it does provide preliminary evidence for further research.
