Summary

To answer the question: "Do Prontosan instillations decrease time to wound and fracture healing and decrease bacterial load compared to wound vac treatment without Prontosan?," we will enroll up to 30 subjects (for an anticipated 20 complete data sets) into this trial. The subjects will be split equally into two different groups by randomization. One groups will have wound vac therapy with Prontosan, and one group will have wound vac therapy without Prontosan. Data related to wound and fracture healing and bacterial load will be assessed between the two groups to determine if wound vac therapy with Prontosan speeds up healing time and decreases bacterial load.

Detailed description

Surgical site infections (SSIs) are a devastating and relatively common surgical complication, occurring in 2% to 5% of patients undergoing surgery in the United States. SSIs can significantly increase patient morbidity, hospital stay duration, healthcare costs, and patient mortality (Anderson 2011). Negative Pressure Wound Therapy (NPWT) with Vacuum-Assisted Closure (VAC) is an established adjunctive treatment option for open wounds that offers the ability to promote healing. However, there is limited evidence for its utility with active infections. Wounds that are acutely infected or that contain an adherent biofilm present a challenging problem (Kim et al 2015). Wound VAC therapy involves cleaning the wound, applying a custom-fit foam to cover the wound, placing a transparent drape over the wound and adjacent skin, and attaching tubing to connect the foam to a VAC suction canister. NPWT is achieved with a pulling force supplied by the VAC suction canister. Typically, suction will remain at a constant pressure until the dressing is removed. Continuous VAC therapy was recently reported to be more effective than standard moist wound care in surgical site infection after ankle surgery (Zhou et al. 2015). VAC therapy with instillations is a novel treatment option that provides the combination of negative pressure with intermittent instillation of a solution. Polihexanide (Prontosan®) is a modern antiseptic that combines a broad antimicrobial spectrum with low toxicity, high tissue compatibility, no reported adsorption and good applicability as solution, gel, ointment, foam and in wound dressing. Unlike other antiseptics, the antimicrobial efficacy of Prontosan® is not impaired in human wound fluid, human tissue or by high loads of blood or albumin. Furthermore, Prontosan® blocks the microbial attachment to surfaces and has been shown to effectively remove biofilms in vitro and in vivo (Hubner et al 2010).
