N2 - An important clinical potential of cold atmospheric plasma (CAP) lies in tumor and wound treatment, whereby the last-mentioned is well-referenced already. However, the underlying mechanisms of improved wound healing have not been sufficiently clarified yet, in particular the influence of CAP on microcirculation. Hyperspectral imaging (HSI) enables the visualization of microcirculation of large tissue areas, thus this technique seems to be a candidate to examine CAP effects on perfusion and oxygen saturation in wounds. During clinical wound management, one chronic wound caused by peripheral arterial occlusive disease and one acute wound after surgical removal of cervical lymph nodes were examined using HSI before and after CAP treatment. HSI was able to demonstrate CAP effects on microcirculation showing a relevant increase of superficial and deeper cutaneous oxygen saturation together with elevated hemoglobin concentration in treated and also surrounding wound area. For the first time, it was shown that CAP improves the superficial and deeper oxygenation and hemoglobin perfusion in and around the treated area of acute and chronic wounds. This effect may contribute to healing support by CAP in wounds. HSI seems suitable for evaluating and monitoring CAP effects in clinical settings.
