Acute Wound, Burn Injury, Burn Scar, Chronic Wound, Flap Disorder
Conditions
Brief summary
In plastic and reconstructive surgery, treatment strategies of second-degree burns, superficial wounds, hypertrophic burn scars, flaps and chronic wounds aim at reducing infection and improving microcirculation. Although previous studies indicate that extracorporeal shock wave therapy (ESWT) 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 extracorporeal shock wave therapy on second-degree burns, superficial wounds, hypertrophic burn scars, flaps and chronic wounds in a human in-vivo setting for the first time.

Eligibility
Inclusion criteria

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.
