The purpose of our study was to verify the benefits of chitosan (CTS) and polylactide (PLA)-based nanofiber wound dressings on a porcine model of a naturally contaminated standardized wound and compare them with the conventional dressings, i.e., gauze and Inadine. Material and Methods The study group included 32 pigs randomized into four homogeneous groups according to the wound dressing type. Standardized wounds were created on their backs, and wound dressings were regularly changed. We evaluated difficulty of handling individual dressing materials and macroscopic appearance of the wounds. Wound swabs were taken for bacteriological examination. Blood samples were obtained to determine blood count values and serum levels of acute phase proteins (serum amyloid A, C-reactive protein, and haptoglobin). The crucial point of the study was histological analysis. Microscopic evaluation was focused on the defect depth and tissue reactions, including formation of the fibrin exudate with neutrophil granulocytes, the layer of granulation and cellular connective tissue, and the reepithelialization. Statistical analysis was performed by using SPSS software. The analysis was based on the Kruskal-Wallis H test and Mann-Whitney U test followed by Bonferroni correction. Significance was set at P < .05. Results Macroscopic examination did not show any difference in wound healing among the groups. However, evaluation of histological findings demonstrated that PLA-based nanofiber dressing accelerated the proliferative (P = .025) and reepithelialization (P < .001) healing phases, while chitosan-based nanofiber dressing potentiated and accelerated the inflammatory phase (P = .006). No statistically significant changes were observed in the blood count or acute inflammatory phase proteins during the trial. Different dynamics were noted in serum amyloid A values in the group treated with PLA-based nanofiber dressing (P = .006). Conclusion Based on the microscopic examination, we have documented a positive effect of nanofiber wound dressings on acceleration of individual phases of the healing process. Nanofiber wound dressings have a potential to become in future part of the common wound care practice.
