Combination of photodynamic therapy and phototherapy for the treatment of cutaneous open wounds in dogs - case reports

The evolution of cutaneous open wounds was evaluated in five client-owned dogs treated with photodynamic therapy (PDT), mediated by methylene blue and phototherapy light-emitting diodes (LED) as the light source. On first day treatment, wound irrigated sterile 0.9% sodium chloride solution, surface dried, 3% solution hydrogen peroxide soaked for 1 minute. mechanically removed and, immediately after, 0.01% used minutes, after which a cluster red LEDs (650 - 670 nm wavelength, 350 mW power, irradiance 200 mW/cm2) used. Subsequently, single sessions, every 48 hours or more, were applied until healing. In general, 24J PDT 12J phototherapy. all cases, associated healed without complications, it may be considered treatment option, especially extensive lesions.
