Hemicellulose dressing versus rayon dressing in the re-epithelialization of split-thickness skin graft donor sites: a multicenter study.

The aim of this study was to compare the effectiveness of a hemicellulose dressing with that of rayon dressing in the healing of split-thickness skin graft donor sites. Twenty-eight patients were selected from five different hospitals and randomized into two groups: hemicellulose dressing group and rayon dressing group. All patients underwent split-thickness skin grafting for various reasons, and the skin graft donor site wounds were covered with hemicellulose dressing (n=14) or rayon dressing (n=14). The donor site was assessed on postoperative days 1, 7, 14, 21, and 28 for hyperemia, pruritus, pain, exudate level, and adherence of the wound dressing. At the 60-day follow-up visit, the donor site was assessed again for pruritus and pain. Touch-pressure, thermal, and pain sensibility tests were performed preoperatively and on postoperative day 60 together with the assessment of color and texture of the re-epithelialized area. In all patients, re-epithelialization was completed between 14 and 21 days after surgery. There were no significant differences between the two groups with regard to pain, hyperemia, pruritus, exudate, and final appearance (color and texture) of the skin graft donor site. The rayon dressing provided significantly better adherence than the hemicellulose dressing, and both dressings showed similar results with regard to the parameters evaluated when used in the treatment of split-thickness skin graft donor sites.
