Brief Summary

Chronic wounds represent a growing challenge in medical care. Part 1: The aim of this part of the study was to collect wound swabs and to answer the question whether the rapid diagnostic tool using enzyme activities can display an infection prematurely. This means that an increased enzyme activity (especially MPO, NHE, LYS, gelatinase, pH) measured overed 3 days, would indicate a change in the wound bed (infection, Inflammation) earlier than the regularly performed clinical assessment. Part 2: The aim of this part of the study was to evaluate (I) the possibility of wound fluid acquisition by means of an "additional collector" during ongoing NPWT and to answer if (II) this secretion can be biochemically analyzed for enzyme activities in order to be able to detect a change in the wound situation at an early stage.

Conditions

Wound; Wound Infection; Wound Contamination; Diagnostic Techniques and Procedures; Negative Pressure Wound Therapy; Biomarker

Keywords

wound infection; negative pressure wound therapy; diagnostic tool; biomarker

Outcome Measures

Primary Outcomes (2)

• Part 1: biochemical analysis of wounds

  Elevated enzyme activities (biochemical analysis of wound swabs) give information of the condition of the wound bed (infection, inflammation).

  during hospitalization

• Part 2: Descriptive assessment of the feasibility of collecting wound fluid during ongoing negative pressure wound therapy

  The aim is to answer the question if it is feasible to collect wound fluid during ongoing negative pressure wound therapy and analyze this wound fluid biochemically.

  during negative pressure wound therapy

Secondary Outcomes (1)

• Part 2: Evaluating changes in enzyme activities in the collected wound fluid

  Starting immediately after installation of the negative-pressure dressing and lasting for 3 days.
