Comparing Outcomes for Prontosan Versus Normal Saline for Negative Pressure Wound Therapy With Instillation

Summary

This is a prospective, randomized trial comparing the outcomes for Prontosan versus normal saline as the solution for negative pressure wound therapy with instillation (NWPTi). Negative pressure wound therapy (NPWT) is a well established method of treatment for acute and chronic wounds. The combination of negative pressure with instillation of a solution is a relatively novel concept that has gained popularity and is currently used nationally and internationally. NPWTi is the standard of care for our division. Despite the growing use, there is limited information regarding the selection of the ideal instillation solution. This is a single site, investigator initiated, NPWTi study comparing the use of Prontosan with normal saline for the adjunctive treatment of the acutely infected wound that requires hospital admission. A total of 100 subjects will be included with 50 subjects in each treatment arm. The outcomes that will be measured are 1) number of operations, 2) length of hospital stay, 3) % of wounds closed prior to discharge, 4) time to closure prior to discharge, 5)% remained closed at 30 day follow-up, and 6) reduction of qualitative bacterial cultures. The results from this study will better characterize the most appropriate use of NPWTi.

Conditions

• Wound Infection

Interventions

DRUG

Normal saline

Normal saline (0.9% NaCl) is an isotonic solution that is widely used for intravenous application but is also used as our SOC for wound irrigation. This solution has high tolerability. Normal saline has been used as the instillation solution for NPWTi. The dwell setting for this solution is 20 minutes. The volume of solution to be used is dependent on the size of the wound hence varies

DEVICE

Prontosan

Prontosan (B Braun, Bethlehem, PA) is 0.1% polyhexanide, 0.1% betaine, sodium hydroxide, and purified water. The polyhexanide is an antiseptic and betaine is a surfactant. This solution is an FDA approved device indicated for topical irrigation. This solution has high tolerability with robust antimicrobial activity. Polyhexanide has been utilized as the instillation solution for NPWTi with positive clinical results. Prontosan is currently being used as the instillation solution for NPWTi in this facility as the SOC. The dwell setting for this solution is 20 minutes. The volume of solution to be used is dependent on the size of the wound hence varies.
