    Abstract:
    Topical antimicrobials are frequently used for local control of infections in burn patients. It has been postulated that these agents retard wound healing. There are limited data about the effects of topical antimicrobial agents on skin graft healing. In this study, we aimed to evaluate the effects of nitrofurazone, 1% silver sulfadiazine, and povidone-iodine on skin graft healing. Forty male rats were used in this study. A meshed skin graft, placed on an excised burn wound, was used as a model to compare topical agents with a control group. Skin graft survival rates, closure of meshed graft interstices (based on physical parameters, namely epithelialization and wound contraction), and histological changes were analyzed. Graft take was more than 85% in all groups. There was no difference between the mean values of the percent graft survival for each group (P > .05). Epithelialization occurred significantly earlier in animals in the nitrofurazone group (P < .05). There was no significant difference between groups in wound contraction rates (P >.05). There was no histological difference between the biopsy specimens of skin grafts. In specimens obtained from the interstices of the meshed graft, no significant differences were found among the groups regarding the wound healing parameters (P > .05). We found that nitrofurazone, silver sulfadiazine, and povidone-iodine had no negative effect on graft healing and take in noncontaminated burn wounds.
