Objective: To assess the efficacy, safety and acceptability of a new
silver poly absorbent dressing (UrgoCleanAg) in the local management
of exudative chronic wounds at risk of infection, with inflammatory
signs suggesting heavy bacterial load.
Method: This prospective, multicentre, non-comparative clinical trial
was conducted in French hospital wards (dermatology and vascular
medicine) or specialised private-practice physicians. Patients were
considered at high-risk of infection when presenting with at least three
of five selected inflammatory clinical signs, suggesting a heavy
bacterial load (pain between two dressing changes, erythema, oedema,
malodorous wound and presence of a heavy exudate). They were
treated for a maximum period of four weeks, and followed by the
physician on a weekly basis, including a clinical examination, area
tracings and photographs. The primary efficacy criterion of the trial was
the relative wound surface area reduction at the end of the four weeks
of treatment. Acceptability was documented by the nursing staff at
each dressing change between the weekly evaluations.
Results: We recruited 37 patients with chronic wounds. Wound
surface area, mostly covered by sloughy tissue, was reduced by 32.5%
at the end of the treatment (median value), while the clinical score
(maximum value of 5, based on inflammatory clinical signs) decreased
from 4.0 to 2.0. Effective debridement properties were documented
(62.5% relative reduction of sloughy tissue at week 4; 58.8% of
debrided wounds at week 4) and improvement of the periwound skin
status was noted (healthy for 28.6% of the patients at week 4 versus
2.7% at baseline). In addition, the tested wound dressing presented a
good safety profile associated to a high level of acceptability, noted by
both patients and nursing staff.
Conclusion: These clinical data support that the tested dressing is a
credible therapeutic alternative for the management of chronic
wounds at risk of infection with inflammatory signs suggesting heavy
bacterial load.

Objective: A description of wounds treated with a poly-absorbent silver dressing (with technology lipido-colloid with silver ions, TLC-Ag), and evaluation of the short-term clinical impact of the dressing on the wound healing process, under real-life conditions.Method: A large, prospective, multicentre, observational study of patients in 81 centres in Germany, presenting with an exuding wound at risk or with clinical signs of local infection for whom the evaluated TLC-Ag dressing (UrgoClean Ag, Laboratoires Urgo, France) has been prescribed. Main outcomes included: reduction in number of wound infections diagnosed and clinical signs of local infection, wound healing rate, clinical assessment of wound healing progression, relative wound area reduction (RWAR), local tolerability, handling and acceptance of the dressing.Results: A total of 2270 patients with acute and chronic wounds of various aetiologies were treated with the evaluated dressing for a mean duration of 22±13 days. All clinical signs of local infection and the diagnosed wound infections were substantially reduced at two weeks after the treatment initiation. All wound infection parameters continued to reduce until the last visit. In the meantime, clinical improvement in wound healing was reported in 98.9% of acute wounds, with a wound closure rate of 68.5%. In chronic wounds, a median RWAR of 57.4% was achieved, with an improvement in healing process documented by clinicians in 90.6% of cases, stabilisation in 6.1% and worsening in 3.2%. Similar results were reported, regardless of exudate level and proportion of sloughy and granulation tissues in the wound bed at baseline. The dressing was well tolerated and well accepted by both patients and health professionals.Conclusion: These results, documented in a large cohort of patients treated in current practice, support and complete the clinical evidence on the healing properties and safety prole of the TLC-Ag dressing in the management of wounds at risk or with clinical signs of local infection, regardless of wound and patient characteristics.Declaration of interest: This study was supported by a grant from Laboratoires Urgo.
