NCT04018469

Brief Summary

  1. 1.This study is a pilot feasibility study to determine treatment effects to estimate sample size for future studies that evaluate wound bacteria colonization.
  2. 2.The secondary objective of this study aims to observe the effect of PED on an open wound and its effects in wound bacteria colonization.

Outcome Measures

Primary Outcomes (2)

  • Bacterial colonization & culture

    Bacteria colonization (cultures results high, moderate, low or negative).

    3 weeks or until amputation, whichever comes first

  • Necrotic tissue assessed through light microscopy of tissue biopsies

    Hematoxylin and Eosin staining of tissue sections to measure extent of tissue necrosis at baseline and compared to tissue obtained at surgery after PED treatment.% necrotic tissue will be measured.

    3 weeks or until amputation, whichever comes first

Secondary Outcomes (3)

  • Wound area measured before and after wound treatment

    3 weeks or until amputation, whichever comes first

  • Bacterial biofilm through Scanning Electron Microscopy analysis

    3 weeks or until amputation, whichever comes first

  • Bacterial contamination assessed through Colony Forming Units

    3 weeks or until amputation, whichever comes first

Sampling MethodNon-Probability Sample
Study Population

In this study 30 patients receiving a below the knee amputation with at least one open wound on the limb will be enrolled. Patients are identified through medical records. The patients will be selected based on inclusion and exclusion criteria through pre-screening through the Comprehensive Wound Center's Limb Preservation Program and wound physicians/providers at Indiana University. Patients enrolled in the study will wear the Patterned Electric Dressing (PED) on the wound(s) for up to 3 weeks or until amputation, whichever comes first and will have up to a total of 4 study visits.

You may qualify if:

  • Ages 18 years and older
  • Patients identified to be receiving a non-traumatic below the knee amputation within 3 weeks of enrollment
  • The affected limb to be amputated must have at least one open wound
  • Wound(s) must be able to be covered by 3x3 dressing
  • Subjects willing and able to provide informed consent

You may not qualify if:

  • Pregnant women
  • Prisoners
  • Individuals lacking consent capacity
