Zimmermann et al. (2020) Cold atmospheric plasma (CAP) for reduction of bacteria with a handheld device (not published)

This retrospective randomized placebo-controlled study included 11 patients with chronic wounds (22 wound areas) that had been present for an average of 2 years. It was designed to show that the reduction in bacterial load in chronic skin wounds is greater when treatment with CAP is carried out in addition to standard treatment. Patients were treated with 2-3 plasma or placebo treatments per week for 1-3 minutes until healing or a maximum of 8 weeks. The treatment was well accepted by all patients, no pain or side effects were reported. In addition, a germ reduction of up to 33.32% was demonstrated in the plasma group compared to the placebo group. Due to the developing COVID-19 pandemic, the study was terminated prematurely.
