RESUMO
A prospective analytic study was performed at the Division of Plastic and Reconstructive Surgery, Department of Surgery, King Chulalongkorn Memorial University Hospital and the Department of Surgery, Chiang Mai University Hospital to compare among Polyvinyl chloride film (PVC film), Op-site and tulle gauze in the treatment of skin graft donor site. From October 1998 to January 2000, 81 donor sites in the same number of patients were treated by three different methods; tulle gauze (26 patients), Op-site (27 patients) and PVC film (28 patients). Each wound was followed until it was completely healed and visual analogue scale was used for pain evaluation. Donor site dressed with PVC film had a healing time of 10.44 days which was not different from Op-site (10.54 days) but significantly faster (p<0.001) than tulle gauze (17.84 days). Pain as measured with visual analogue scale in the group of PVC film (1.48) was not different from Op-site (1.34) but significantly less than (p<0.001) tulle gauze (5.45). There was no difference in the rate of infection between each group. In conclusion, the authors found no difference between Op-site and PVC film in healing time and pain. Both of them were better than tulle gauze. The results demonstrate the usefulness of PVC film as a donor site dressing as it promises relatively rapid healing, less pain and is inexpensive.
