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.

- The secondary objective of this study aims to observe the effect of PED on an open wound and its effects in wound bacteria colonization.
Read the detailed description
This study is designed as a pilot study where 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. The decision of amputation is made independently of the study and is solely made by the patient and their physician/provider. The provider decides based on the severity of the limb's condition if/when the limb should be amputated and will schedule this surgery with the patient based on current clinical standard of care. Study participation is decided independent of clinical decision. 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Bacterial colonization & culture
Bacteria colonization (cultures results high, moderate, low or negative).
Measured: 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.
Measured: 3 weeks or until amputation, whichever comes first
Secondary outcomes (3)
Wound area measured before and after wound treatment
To determine the effect of PED on % wound closure based on wound measurements at baseline and end of PED treatment.
Measured: 3 weeks or until amputation, whichever comes first
Bacterial biofilm through Scanning Electron Microscopy analysis
Perform scanning electron microscopy to detect bacterial biofilm (high, moderate, low or negative) before and after PED treatment.
Measured: 3 weeks or until amputation, whichever comes first
Bacterial contamination assessed through Colony Forming Units
Colony forming units will be measured from tissue samples and dressings to quantitate bacterial contamination levels at baseline and after PED treatment.
Measured: 3 weeks or until amputation, whichever comes first

Questions about this trial
What is this clinical trial studying?
An observational study of Amputation and Open Wound, run by Gayle Gordillo at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 19 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Bacterial colonization & culture (time frame: 3 weeks or until amputation, whichever comes first). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04018469, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Apr 2022.
