چکیده
PVA foam has been used as a temporary skin substitute since 1977. PVA is a white, monolayered, microporous sponge. In animal experiments it was shown that cell detritus, fibrin-fur and microorganisms were taken in and kept inside the material. This effectively cleans the wound surface, the so-called “microdebridement” process. The effect is due to a strong adherence and a high capacity to absorb fluids, just at the time that the wound is infected.

Analysis of Effective Interconnectivity of DegraPol-foams Designed for Negative Pressure Wound Therapy
Many wounds heal slowly and are difficult to manage. Therefore Negative Pressure Wound Therapy (NPWT) was developed where polymer foams are applied and a defined negative pressure removes wound fluid, reduces bacterial burden and increases the formation of granulation tissue. Although NPWT is used successfully, its mechanisms are not well understood. In particular, different NPWT dressings were...
متن کاملChanges of anabolic processes at the cellular and molecular level in chronic wounds under topical negative pressure can be revealed by transcriptome analysis
Chronic wounds--as defined by the World Union of Wound Healing Societies (WUWHS)--are a considerable worldwide health care expense and impair quality of life. In order for chronic wounds to heal, these wounds must be transformed to a more acute state to begin the healing process. Topical negative pressure (TNP) with reticulated open cell foam (ROCF) is known to promote healing in certain types ...
متن کاملA blinded, prospective, randomized controlled trial of topical negative pressure wound closure in India.
Wound closure using topical negative pressure (TNP) has been reported to be effective, but equipment costs can be prohibitive in resource-challenged countries. Because nonhealing wounds are exceedingly common in developing countries such as India, the ability to optimize wound care with limited resources is very important. To investigate the feasibility and efficacy of providing TNP in an India...
متن کاملAdvances in wound healing: topical negative pressure therapy.
In clinical practice many wounds are slow to heal and difficult to manage. The recently introduced technique of topical negative pressure therapy (TNP) has been developed to try to overcome some of these difficulties. TNP applies a controlled negative pressure to the surface of a wound that has potential advantages for wound treatment and management. Although the concept itself, of using suctio...
متن کاملSkin graft fixation in severe burns: use of topical negative pressure.
Over the last 50 years, the evolution of burn care has led to a significant decrease in mortality. The biggest impact on survival has been the change in the approach to burn surgery. Early excision and grafting has become a standard of care for the majority of patients with deep burns; the survival of a given patient suffering from major burns is invariably linked to the take rate and survival ...
