An RCT to compare a bio-cellulose wound dressing with a non-adherent dressing in VLUs

Area of Science:

• Wound Healing
• Dermatology
• Regenerative Medicine

Background:

• Venous leg ulcers (VLUs) represent a significant clinical challenge.
• Effective wound management is crucial for patient outcomes and reducing healthcare burden.

Purpose of the Study:

• To compare the efficacy of a bio-cellulose wound dressing (BWD) against a non-adherent wound contact layer in treating VLUs.
• To evaluate debridement, granulation, re-epithelialization, ulcer size reduction, and pain in VLU outpatients.

Main Methods:

• A prospective, randomized, controlled multicenter study involving 48 VLU patients.
• Patients received compression bandages with either standard care (non-adherent dressing) or BWD (Suprasorb X).
• Outcomes assessed weekly over 12 weeks included debridement efficacy, time to granulation and re-epithelialization, ulcer size, and pain.

Main Results:

• Autolytic debridement was significantly faster with BWD (84% tissue removal vs. 26% for controls, p < 0.0001).
• Median time to 75-100% granulation was 25 days for BWD vs. 36 days for controls.
• Median time to ≥50% re-epithelialization was 36 days for BWD vs. 50 days for controls.
• Patient-reported pain reduced significantly faster with BWD, with 100% reporting no pain by week 7 compared to 63% of controls.

Conclusions:

• BWD demonstrated faster and more effective autolytic debridement compared to standard care.
• Pain reduction was significantly more rapid in the BWD group.
• While BWD showed a shorter time to healing, this difference did not reach statistical significance.
