title: Impact of ischemia on tissue oxygenation and wound healing: improvement by vasoactive medication.
abstract: The influence of vasoactive medication on tissue oxygenation and wound healing was investigated in the ear model of the hairless mouse. Ischemia was induced to the ears by ligating 2 of the 3 main vessel bundels and verified by measurements of tcpO2. Reduced tissue oxygenation was followed by a prolongation of the time required for complete healing of standardized wounds. Treatment with the vasoactive drug Buflomedil (3 mg/kg/day iv.) resulted in enhanced recovery of the tissue from reduced oxygenation and likewise reversed the adverse effects of ischemia on wound healing. These results warrant the use of the drug in patients suffering from delayed wound healing due to peripheral arterial disease.
