Background: The major morbidity of split skin graft is donor site pain, soaking and delayed healing. Numerous donor site dressing modalities are available, but the ideal material remains elusive. Method: We compared the effect of bovine type 1 collagen dressing to conventional paraffin impregnated gauze dressing in 20 patients. After harvesting graft by standard technique, one-half was covered by collagen sheet and other half by paraffin gauze. Pain was assessed daily by Visual Analog Scale. Any soaking of dressing was noted. The dressing was removed on 10th day and both areas were inspected for the amount of epithelization. Results: The pain was less in the collagen area when compared to the paraffin gauze area. The difference was highest for the first 3 days (2.16 vs. 5.86, P < 0.01) reduced for the next 4 days (0.4 vs. 3.4, P < 0.01) and was minimal for the last 3 days (0 vs. 1, P > 0.02). Seven patients had soaking limited to paraffin gaze area whereas two patients had soaked in both areas. On removal of dressing on 10th day, average epithelization was slightly higher in collagen area (98%) compared with the paraffin gauze area (95%). Conclusion: Bovine type 1 collagen reduces pain and soaking at skin graft donor site with minimal effect on the rate of epithelization.
