Clinical Assessment of the Efficacy of a Single-Use Negative Pressure Wound Therapy System, Compared to Traditional Negative Pressure Wound Therapy in the Treatment of Venous Leg Ulcers and Diabetic Foot Ulcers: A Randomized Controlled Trial
At least 70% of leg ulcers are the result of chronic venous insufficiency1
Diabetic foot ulcers (DFUs) affect 15 – 25% of all diabetic subjects during their lifetime1,3,4 and precede 84% of all lower leg amputations.5 For DFUs that fail to improve (>50% wound area reduction) after four weeks of standard wound therapy it is recommended to consider the use of adjunctive wound therapy options, including Negative Pressure Wound Therapy (NPWT)6
Equivalent clinical outcomes have been noted in comparative studies of traditional Negative Pressure Wound Management (tNPWT) systems.7,8 tNPWT may be complicated to apply and use, and the size of the pump and the canister may be intrusive and limit patient mobility2,8,9
Single Use Negative Pressure Wound Therapy (sNPWT) systems are based on the same principles of action as tNPWT systems, but are smaller and disposable.8 Therefore, for approved indications, sNPWT systems are expected to simplify the application and management of NPWT, at the same time making the therapy accessible to more patients, including active and homebound individuals10
