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.

Eligibility

Inclusion Criteria:

Group A (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 B (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 C (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 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.

Intervention

Procedure:
• Intervention: Remote Ischemic Preconditioning
Remote Ischemik Preconditioning is performed using a Blood Pressure Cuff with a pressure slightly above patients' blood pressure on the upper arm.
