To evaluate the performance and safety of this fibre wound dressing incorporating Hydrolock technology, in the management of highly exuding diabetic foot ulcers (DFUs).
This research puts
emphasis on an antiseptic, nonwoven fibre dressing which can be applied on a
vast range of exuding wounds like pressure ulcers, surgical wounds, leg and
foot ulcers etc. This dressing has proved to be beneficial as it has the
ability to absorb, heal the wound and retain exudate.
To evaluate the
performance and safety of this fibre wound dressing incorporating Hydrolock
technology, in the management of highly exuding diabetic foot ulcers (DFUs).
The study was
conducted over a 12-week period involving a total of 21 patients with DFUs. A
number of parameters were measured to monitor the change in condition of the
peri-wound skin from baseline assessments. The evaluation of dressing-related
pain was measured using a 100mm visual analogue scale (VAS). Wound status
(measured by changes in wound size and healing phase) was recorded.
Clinician/patient opinions of the test product and technical performance
(measured by the presence of dressing residue following removal and handling of
wound exudate) were also recorded.
The number of
patients with healthy/intact peri-wound skin increased from baseline to the
final visit. There was also a steady decrease in wound exudate volume
throughout the study. Pain levels were very low throughout the investigation
period, bearing in mind issues with neuropathy. A gradual decline in all wound
size parameters from baseline to the final visit was noted; there was a
statistically significant reduction in both wound area (cm2), p=0.0094,
and wound volume (cc), p=0.0056, from baseline to the final visit. Throughout
the study, a small decline in the mean percentage of granulation tissue within
the wound paralleled a gradual increase in the mean percentage of
epithelialization tissue, while the percentage of non-viable tissue remained
very low. The primary endpoints of product performance and safety were measured
by the changes from baseline in the condition of the peri-wound skin. Results
showed that the number of patients with healthy/intact peri-wound skin
increased from baseline to the final visit, increasing from 6 patients (28.6%)
at baseline to 14 patients (66.7%) at the final visit. There were no
occurrences of product degradation on the skin and no reported adverse events
(AE)/adverse device effects (ADE) during the course of the study that were judged
to be related to the investigational product.
This study has
demonstrated the capacity for the test dressing to minimize damage to the
peri-wound skin and dressing-associated pain. Despite the majority of wounds
remaining unhealed at the final visit, improvements were noted in terms of
tissue type and a significant reduction in wound area and volume. The technical
performance of the dressing was demonstrated by an ability to absorb and retain
exudate. Product safety was also demonstrated by an increase in the number of
patients with healthy/intact peri-wound skin and the lack of identified
product-related AE/ADEs.
