Primary Outcome Measures:
  • Change in skin microbial colonization over 7-day period of antimicrobial dressing application [ Time Frame: Assessed after 4 days and 7 days of dressing application ]
    Mean number of Colony Forming Units (CFUs) per square centimetre (cm²) of skin prior to treatment (baseline), following prepping with 70% isopropyl alcohol and following post treatment samplings of IV Clear™, Tegaderm™ CHG and Silicone control dressings collected.

Enrollment: 37
Study Start Date: April 2011
Study Completion Date: July 2011
Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: IV Clear™ Device: IV Clear™ Dressing
Polyurethane film, silicone adhesive dressing with chlorhexidine and silver
Active Comparator: Tegaderm CHG™ Device: Tegaderm CHG™
Polyurethane film, polyacrylate adhesive and a polyol hydrogel containing 2% w/w chlorhexidine gluconate
Placebo Comparator: Vehicle Control Dressing Device: Silicone Vehicle Control Dressing
Polyurethane film with silicone adhesive dressing, without antimicrobials

Detailed Description:

A single center, within-subject randomized study design in healthy adult subjects with a history of high bacteria counts on their upper back, meeting the inclusion criteria.

Antimicrobial efficacy will be measured by determining the mean number of Colony Forming Units (CFUs) per square centimetre (cm²) of skin prior to treatment (baseline measurement), following preparation with 70% isopropyl alcohol, and following post treatment samples.

The goal of this study is to demonstrate that IV Clear™ is as effective as or better than Tegaderm™ CHG dressing in preventing regrowth of cutaneous microbial flora on test subjects.


Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All

  • Are willing to refrain from using antimicrobial soaps for bathing and showering during the entire study
  • Are willing to refrain from swimming in chemically treated pool or hot tub for duration of study
  • Are willing to refrain from using antimicrobial/medicated lotions and creams for duration of study, unless prescribed by a physician for an intercurrent illness
  • Are willing to refrain from using topical or systemic antibiotic medication for duration of study, unless prescribed by a physician for an intercurrent illness

Exclusion Criteria:

Subjects will not be enrolled in the study if they:

  • Have any medical condition which in the opinion of the Investigator prelude participation
  • Have swam in chemically treated pools or hot tubs two weeks prior to any microbial sampling
  • Have used UV tanning lamps two weeks prior to any microbial sampling
  • Have tattoos, dermatoses, abrasions, cuts, lesions or other skin disorders on test sites
  • Have bathed or showered less than 48 hours prior to any microbial sampling
  • Have known sensitivity to adhesive products, or to materials used in test articles
  • Have participated in any type of back wash study within 7 days prior to study
  • Have a known sensitivity to latex products
  • Are not willing to fulfill the requirements of the protocol
