Brief Summary

In plastic and reconstructive surgery, treatment strategies of second-degree burns, superficial wounds, burn scars, flaps and chronic wounds aim at reducing infection and improving microcirculation. Although previous studies indicate that Plasma Therapy can accelerate wound healing, only a few studies focused on the elucidation of its mechanisms of action. Therefore, the aim of this study is to evaluate the microcirculatory effects of Plasma Therapy on second-degree burns, superficial wounds, burn scars, flaps and chronic wounds in a human in-vivo setting for the first time.

Group D (n=20): Consent-capable healthy male and female probands ≥18 years of age serving as sham group. None of the the criteria of groups A-C must be evident. No soft tissue injury must be evident.

Group E (n=20): Consent-capable male and female patients ≥18 years of age who have sustained a second-degree burn on ≥1% and ≤30% of the surface of the body.

Group F (n=20): Consent-capable male and female patients ≥18 years of age who require a skin excision for the purpose of a skin graft. The minimal size of the skin-graft donor site must not be less than 1% of TBSA.

Group G (n=20): Consent-capable male and female patients ≥18 years of age suffering from a wound that has not yet healed ≥3 weeks. The minimal size of the wound site must not be less than 1% of TBSA.

Group H (n=20): Consent-capable healthy male and female probands ≥18 years of age serving as sham group. None of the the criteria of groups E-G must be evident. No soft tissue injury must be evident.

Group J (n=20): Consent-capable male and female patients ≥18 years of age suffering from a hypertrophic burn wound.

Group K (n=20): Consent-capable male and female patients ≥18 years of age received a flap.

Group L (n=20): Consent-capable male and female patients ≥18 years of age received a flap.
