Abstract
The objective of this study was to investigate the healing effect of five different products on split-thickness skin graft (STSG) donor sites and full-thickness cutaneous wounds (FTCWs) using an occlusive dressing model. Six groups were included: 1 control and 5 experimental groups, with a total of 24 rats, using an occlusive dressing model. STSG donor sites and FTCWs were established in two separate areas, to the right and left on the animals' backs. Wound sites were dressed with one of the following materials: fine mesh gauze, microporous polysaccharide hemosphere (MPH), clinoptilolite, alginate, hydrogel or biosynthetic wound dressing (Biobran(®) ). These materials were compared in terms of healing rate, healing quality and histopathological findings. Occlusive dressings were applied to each wound on days 0, 3, 5, 7, 10 and 14. Area measurements were taken using images of each dressing. The alginate and clinoptilolite groups gave the best healing rate results for both STSG donor sites (P = 0·003) and FTCWs (P = 0·003). MPH came third in each group. The alginate group produced better results in terms of healing quality criteria, followed by hydrogel, MPH, clinoptilolite and Biobran(®) , in that order. Statistically significant results were obtained in all groups compared to the control group (P < 0·0007). Rapid and good healing quality for both the STSG donor sites and FTCWs were obtained with alginate. Healing with clinoptilolite and MPH was rapid, but poor quality, while slower but good healing quality was obtained with hydrogel. Slower and worse quality healing was obtained with Biobran(®) .
