Comparing Chitosan Sponge With Hydrocolloid as Dressing for Split-thickness Skin Graft Donor Site Wounds

The goal of this clinical trial is to compare whether chitosan sponge have same clinical efficacy as a hydrocolloid dressing in treating skin graft donor site wounds. The main questions it aims to answer are: Does chitosan sponge show comparable clinical efficacy as a split-thickness skin graft donor site dressing compared with a conventional hydrocolloid dressing? Participants will: The skin graft donor site wound will be divided into equal halves, and a chitosan sponge and hydrocolloid dressing will be applied to the same patient. The rate of epithelialization will be assessed on days 10, 15, and 20 pain score, pruritus score, ease of removal, exudate level, and bleeding will be assessed on days 10, 15, and 20 The scar outcome will be assessed 2 months and 6 months post-procedure
