Combination of a Polymeric Membrane Dressing Plus Negative Pressure Wound Therapy Against Negative Pressure Wound Therapy Alone

In surgical units negative pressure wound therapy (NPWT) is often used to facilitate wound healing. The recommended frequency of change every third to fourth day causes an immense workload. The purpose of this study is to evaluate the effect of an additional polymeric membrane interface dressing (PolyMem® WIC) as primary wound contact layer in NPWT in comparison to NPWT alone on the number of required dressing changes until wound closure as the primary endpoint. Secondary endpoints are: time to heal and wound associated pain.
