About this trial

This is an interventional basic science trial for Burn Injury

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

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.

Exclusion Criteria:

General exclusion criteria

  • below 18 years of age
  • wounds requiring artificial respiration, since consent for the study participation is unobtainable

Exclusion Criteria Groups A, B, D:

  • peripheral arterial occlusive disease
  • vasculitis

5. Study Description

Brief 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.
