Split thickness skin grafting is a common reconstructive technique for the treatment of patients with deep burns and other traumatic injuries. Various types of dressing materials are available for the management of donor site after harvesting a split thickness skin graft such as semi permeable film dressings, semi permeable foam dressings, hydrogels, hydrocolloids, alginate dressings, bioactive wound dressings such as collagen, hyaluronic acid, chitosan and elastin or tissue engineered, medicated and composite dressings. Selection of an ideal dressing in such vast variety is a challenge. Thus, this study is aimed at most common presentation of the patient which is pain as primary outcome and similarly surgical site infection and time of epithelialization as secondary outcomes.

Vaseline gauze is a sterile, occlusive dressing consisting of fine mesh, absorbent gauze impregnated with approximately three times its weight of white petrolatum. 

Collagen sheet is a biological dressing derived from bovine source, comprising mostly type I and type III collagen which is retained in the tissue and gradually absorbed. 

Both dressings are commonly used and there is no ethical issue associated with their usage.

The primary objective of my study is to compare severity of pain with use of each dressing based on numerical pain rating scale where patient will rate the severity of his/her pain out of 10 (10 being most severe) on post-operative days 01, 07, 14 and 21. I have considered pain as primary objective because that is what the patient is most considered about. Similarly, my secondary objectives are to compare the number of days for epithelialization which is the number of days required for healing of the wound and presence or absence of surgical site infection. Thus, the study will also compare and analyze with usage of which dressing material the wound will heal faster and in which group surgical site infection is common.
