    Despite the long history of skin grafting, there is no standardized treatment for split-thickness skin graft donor sites. These sites cause a notable amount of pain and discomfort to the patients and open wounds also introduce a risk for infection. There is an extensive need for treatment options promoting the fastest and least painful healing possible while also being infection-free. The treatment of split-thickness skin graft donor sites is constantly studied and there is plenty of scientific literature available about this topic. In the theory section of this Master’s thesis, the structure of skin, the process of wound healing, skin grafting surgery and wound care products for split-thickness skin graft donor sites are briefly introduced. Additionally, the method of systematic review is described. In the empirical section, a systematic review is performed to compare animal- and non-animal-based wound care products in the treatment of split skin graft donor sites. The methodological quality of the included studies is reviewed. In the literature search, 3552 references were found. In this systematic review a total of 23 articles were included comprising of 21 comparative clinical studies and two previous literature reviews. Of the original studies, 20 reviewed healing, 14 infection and 17 pain of the split-thickness skin graft donor sites. Based on the results of the systematic review, animal-based wound care products might promote healing and reduce pain experienced by patients in the treatment of split-thickness skin graft donor sites when compared with non-animal-based wound care products. The results concerning infection were inconsistent. Generally, the reporting of the clinical original studies was not comprehensive enough for proper evaluation of methodological quality. Some defects, mostly in the blinding of the patients, study personnel and the assessors of outcomes, were also found. Moreover, the studies were heterogeneous in their definitions and measuring of the reported outcomes. Therefore, there is substantial uncertainty in the results of this systematic review. The systematic and transparent way of conducting the literature search, the review of the methodological quality and the reporting of the outcomes can be considered as a strength of this thesis. The main weakness is, that only one person performed the critical steps of this study, which might increase the risk of bias and reduce the repeatability of the study.
