Clinical Trial Summary

In plastic and reconstructive surgery, treatment strategies of second-degree burns, superficial wounds and chronic wounds aim at reducing infection and improving microcirculation. Although previous studies indicate that remote ischemic preconditioning (RIPC) 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 remote ischemic preconditioning on second-degree burns, superficial and chronic wounds in a human in-vivo setting for the first time.
