Cold plasma in wound healing

Even today, not all wounds can be healed. Treatment, which often takes many years, is a burden for patients and is very cost-intensive. Therefore, additional procedures such as cold plasma are becoming increasingly popular. Active components of cold plasma include electromagnetic radiation and free radicals. The active principle is based on, among other things, damage to bacterial cells and positive interaction with epithelial and endothelial cells. Angiogenesis and cellular oxygen metabolism are stimulated. The evidence base is still limited and heterogeneous, as some results are contradictory and comparability is difficult. However, new, well-designed studies have confirmed previous findings. In order to create a solid database, further studies are needed.
