Risk assessment of the application of tissue-tolerable plasma on human skin

The results of the risk assessment of the tissue-tolerable plasma (TTP) jet kINPen med® and first results of pilot clinical studies are presented. Producing an atmospheric pressure plasma, this plasma jet entails no risk for humans in terms of temperature increase, UV radiation or free radical formation by the plasma. The antiseptic efficacy in vitro on porcine skin and in vivo on human skin was compared to that of octenidine. TTP could significantly reduce the bacterial load in comparison to untreated skin. However, the slightly reduced antiseptic properties of TTP are attributed to the current parameter set-up and technical limitations.
