Microcurrent Dressing to Treat Infections, Before, During and After Surgery

September 16, 2020 updated by: Bruce Miller, University of Michigan

Evaluation of a Microcurrent Dressing for Prophylaxis Against Perioperative Prosthetic Joint Infection

Deep periprosthetic infection following total joint arthroplasty is a major complication. Although it only occurs in a small percentage of patients (~1%), it results in substantial morbidity and a decline in functional outcome. A two stage revision and exchange is commonly required in order to clear the infection and provide the best opportunity for prosthetic replantation. Following removal of the infected components, a minimum course of six weeks of parenteral antibiotics is given and resolution of the infection confirmed through the ESR, CRP, and repeated aspiration of the joint. In most instances a temporary spacer of antibiotic-loaded cement is inserted at the first stage and removed at the second operation.

Propionibacterium Acnes is a gram-positive, non-spore-forming, anaerobic bacillus found in lipid-rich areas, including hair follicles, sebaceous glands, and moist areas of the shoulder and axilla. Because of its low virulence, infections caused by P. acnes typically have a low-grade, indolent course, with shoulder pain often the only presenting symptoms after prosthetic replacement. P. acnes is particularly challenging to both diagnose and to eradicate, and is a substantial source of morbidity with shoulder arthroplasty.

JumpStart™ is a wireless, advanced microcurrent generating, dressing used for the management of surgical incision sites. Microcell batteries made of silver and zinc, generate an electrical current when activated by conductive fluids, such as saline, hydrogel or wound exudate. These microcells create low voltage electrical fields to stimulate the surrounding area and to provide antimicrobial protection to assist with wound healing. JumpStart has demonstrated superior broad spectrum bactericidal activity of a wound dressing against antibiotic-resistant strains of wound isolates within 24 hours.

The use of JumpStart as a prophylactic preoperative dressing to alter the skin flora and thereby decrease the risk of prosthetic infection has not been investigated to-date. Given the morbidity of a prosthetic infection, this would be a remarkably valuable intervention for any joint replacement procedure.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Measurement of Change in Cutibacterium Acnes
Time Frame: 2 days pre-operatively and at the time of surgery

All topical and deep tissue specimens were planned to be cultured for Propionibacterium Acnes. The type and number of colony forming units (CFU) will be recorded. Propionibacterium was renamed during the course of the trial, so the actual bacteria culture was Cutibacterium.

Swabs for topical bacteria collections were taken 48 hours apart; biopsies to check on bacterial depth were taken at time of surgery.

Bacteria CFU counts were classified into 5 categories: None, Minimal, (1-5 colonies) Few, (6-15 colonies) Moderate (16-99 colonies) and Numerous (100 or greater).

Participants are categorized by their initial count categories and their change (expressed as reduction, no change, or increase) in CFU count (categorized) as measured by skin swabs; Biopsy count category discrepancies from time of surgery swab are only shown if they were a more than 1 category difference.
2 days pre-operatively and at the time of surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cosmesis and Apposition
Time Frame: At 7 days and then again 10-14 days postoperatively
Investigator determined from a small number of collected images that because of the number of arthroscopies rather than arthroplasties performed, the surgical wound was not large enough to evaluate the wound healing effect of dressings. Photo collection was discontinued and that data was not analyzed
At 7 days and then again 10-14 days postoperatively
