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

Objective: To compare the efficacy of a bio-cellulose dressing (BWD) versus a non-adherent wound contact layer in venous leg ulcer (VLU) outpatients. Method: In a prospective, randomised, controlled multicentre study, 48 VLU patients were randomised to receive compression bandages and either standard care (non-adherent dressing; n=23) or a BWD (Suprasorb X; n=25). VLUs were evaluated for debridement efficacy, time to 75-100% granulation and ≥ 50% re-epithelialisation, reduction of ulcer size and patient-reported ulcer pain, comparing the status at day 0 and weekly, over a 12-week study treatment period. Results: Thirty-three patients (n=18 BWD and n=15 control dressing) were included in the analysis. Autolytic debridement was significantly faster in the BWD group, with an 84% removal of yellow tissue compared with 26% in the control group, over the 12-week period (p < 0.0001). A median of 25 days were required to achieve 75-100% granulation in the BWD group vs 36 days for controls. A median of 36 days was...
