Abstract:
PURPOSE: Pseudomonas aeruginosa is an etiologic agent in serious wound infection. Pseudomonas aeruginosa infection is problematic because this organism is resistant to many antimicrobial drugs. The purpose of this study was to compare the bactericidal effect of commonly used topical agents and their effect on wound healing. METHODS: Pseudomonas aeruginosa-infected full- thickness skin defect was developed on the mouse to compare 3 commonly used topical agents-Betadine, 2% Gentamicin solution and 0.3% Acetic acid with the control group. Wound size change, bacterial colony counts and histologic findings of each groups were analyzed. RESULTS: The wound size decreased in all treated groups as compared with the control group. However, there was no statistical difference. Gentamicin solution group was showed the lowest bacterial colony count and statistically significant difference compared with the control group(p=0.032). Other treated groups were also effective against Pseudomonas aeruginosa, but not different statistically. Histologic findings revealed that epithelialization, granulation tissue formation and microvessel proliferation were increased and necrosis and inflammation were decreased in all treated groups compared to the control group, but not different statistically. Betadine group significantly increased granulation tissue formation compared to the control group (p= 0.041). CONCLUSION: There is no universal topical agent that enhances most aspects of wound healing while simultaneously decreasing the bacterial concentration. However, Gentamicin solution may be an optimal topical agent for Pseudomonas aeruginosa infected wound. Further study should experiment on human with Gentamicin solution to confirm a effect on Pseudomonas aeruginosa infected wound for clinical applications.
