ABSTRACT
Introduction: The treatment of chronic wounds constitutes a massive financial burden to society and our health-care system. Therefore, efficient wound care is of great importance to all kinds of medical fields. The implementation and modification of negative-pressure wound therapy can be seen as a major improvement in wound healing. Many different NPWT applications evolved trying to address various wound etiologies.
Areas covered: This review aims to give an overview of various NPWT applications, show its effects on wound healing, and discuss future modifications.
Expert opinion: NPWT as a delivery device for cold plasma, growth factors, or targeted stem cells to the wound bed and the ability to monitor the inflammatory activity, bacterial load and wound healing factors can be seen as possible future steps to individualized wound care. In addition, it requires high-quality experimental studies to develop the ideal foam in terms of microstructure, pore size, and material properties.
Article Highlights
Negative-pressure wound therapy has shown to be an effective treatment modality for various types of wounds.
Closed incision negative-pressure wound therapy shows improved tissue perfusion close to the wound edges and reduced infection and wound dehiscence rates.
Negative-pressure wound therapy with instillation and dwell time possesses huge potential especially for infected wounds.
The enhancement of various foam properties (such as biological degradability) can broaden the clinical use of NPWT in the future.
The delivery of various wound-specific substances such as stem cells and growth factors at a desired rate and dose using NPWT with instillation can play an important role in future wound management.
