Gas plasma: Medical uses and developments in wound care

Abstract

(Figure Presented) Non Thermal gas Plasmas (NTGPs) are a promising emergent medical technology. Unlike thermal plasmas, they generate a complex room temperature mix of reactive species which interact with tissues. The characterization of candidate plasmas and their interaction with tissues has shown that they produce a variety of broadly dose dependent effects ranging from fibroblast proliferation to angiogenesis and bacterial destruction. These findings, supported by recent experiments using skin models, suggest that NTGP's could potentially play an important role in both decontaminating acute and chronic wounds and accelerating healing. However, important issues over toxicological and environmental safety remain unanswered and a number of regulatory and technical hurdles will need to be overcome before a NTGP medical device is released. © 2010 WILEY-VCH Verlag GmbH 81 Co.
