This article investigates the application values of Xenogenic (porcine) acellular dermal matrix (XADM) in preparation of a Fournier gangrene wound bed. Thirty-six consecutive cases of patients with Fournier gangrene between 2002 and 2012 were enrolled in our department of our hospital. The patients were divided into two groups according to different methods of wound bed preparation after surgical débridement, including the experimental group (17 cases) and the control group (19 cases). The wounds in the experimental group were covered with XADM after surgical wound débridement, whereas the wounds were cleaned with hydrogen peroxide and sodium hypochlorite solution (one time/day) in the control group. The wound bed preparation time and hospital stay were then compared in the two groups. The wound preparation time was 13.64 ± 1.46 days and hospitalization period was 26.06 ± 0.83 days in the experimental XADM group. In the control group, the wound bed preparation time and hospitalization period were 22.37 ± 1.38 and 38.11 ± 5.60 days, respectively. The results showed statistical differences between these two groups. When used in wound débridement after Fournier gangrene, XADM protects interecological organizations, promotes the growth of granulation tissues, and maximally retains function and morphology of the perineum and penis.

Porcine acellular dermal matrix (pADM) was modified by N-(2-Hydroxy) propyl-3-Trimethyl Ammonium Chitosan Chloride (HTCC) with varied concentration, pH, time and temperature. The absorption of HTCC, surface state, hydrophilicity, antibacterial properties and cytotoxicity of pADM were researched before and after modification. Results show that the optimum experimental condition of modification is pH 6.4, 37°C, treated for 48 hours, and the concentration of HTCC 0.7%. The contact angle of modified pADM reduces and the water absorption ratio increases, but the tensile strength and moisture permeability falls. Obvious antibacterial action is observed on Escherichia Coli and Staphylococcus Aureus, and cytotoxicity is grade 2. This work suggests the feasibility of HTCC to modify pADM.
