Clinical case study of the efficacy of a hydrocellular polyurethane foam dressing with a silicone adhesive in the treatment of a diabetic foot ulcer

Introduction: The 4 basic aspects of Wound Bed Preparation (WBP)  can now be represented by an acronym, TIME. T= tissue (non-viable or deficient), addressed clinically via debridement. I= infection or inflammation, addressed clinically via antimicrobial agents. M= moisture control, addressed clinically via absorbent dressings and/or compression. E= epidermal margin, addressed clinically via tissue engineered constructs/grafts. Hydrocellular

polyurethane foam dressings with a silicone adhesive is a wound care technology with the ability to maintain a moist wound environment while protecting the periwound skin from adhesive trauma.

 

Purpose/Objective:

The purpose of this study is to investigate the efficacy of a hydrocellular polyurethane foam dressing in a patient with a silicone adhesive as per its ability to address the M of the TIME principle of WBP while protecting the periwound skin from adhesive trauma.

Method: A variety of parameters were evaluated in this case, such as wound progress towards wound closure & appearance of the wound and surrounding skin. Also product performance parameters (wear time, ease of use, conformabilty, pain upon removal , patient comfort, clinician satiscftion, etc. were also evaluated.

 

Results: 87 y/o female with a DFU. The patient’s wound was 5 months duration upon admittance. The ulcer was 6.8 cm² in area and 0.4 cm in depth, contained yellow slough. The level of pain and exudate were moderate. The condition of the periwound skin was macerated and fragile. Over a period of 22 days the wound completely healed. The periwound skin improved and was considered healthy at the end of the study.

Conclusion: The hydrocellular polyurethane foam dressing with a silicone adhesive was beneficial in maintaining a moist wound environment which helped the wound to close. In addition the periwound skin improved over the course of treatment. The dressing performed as expected.
