The biomechanics of negative-pressure wound therapy
Despite the success of negative-pressure wound therapy, its mechanism of action remains unclear. The common perception that it reduces tissue pressure and increases perfusion has recently been challenged following the observation that tissue necrosis can be caused as a result of its application. A …

INTERACTION OF NEGATIVE PRESSURE WOUND THERAPY AND COMPOSITE BIOMATERIALS FOR SPINAL FUSION
… 2014, Rajaee et al. 2012, Stranges et al. 2009). Negative pressure wound therapy (NPWT) or vacuum assisted closure (VAC) has shown superior clinical results when used in combination with biomaterials to accelerate wound healing in treating complicated wound with exposed bone (Wijewardena et al. …

Negative Pressure Wound Therapy - Effects on Sternotomy Wounds and the Intrathoracic Organs
Negative pressure wound therapy (NPWT) has been widely adopted for the treatment of deep sternal wound infections due to its excellent clinical outcome. However, the mechanisms of action and effects on hemodynamics have not been thoroughly elucidated. The aims of the work presented in this thesis …

Design and development of a smart, self-contained, portable negative pressure wound therapy device
Negative pressure wound therapy (NPWT) is a commonly used treatment in which the application of a low vacuum (-20kPa) is used to accelerate the recovery of chronic, hard-to-heal wounds. Costs of chronic wounds such as diabetic foot ulcers are estimated to be $25 billion, with 6.5 million patients …

Negative Pressure Wound Therapy - Mechanisms of Action and Protecting Exposed Blood Vessels in the Wound Bed
… severe complications and bleeding when used in wounds with exposed blood vessels. The aims of this work were to investigate the mechanisms of action of NPWT and to explore the possibility of using thin plastic discs to protect exposed blood vessels in the wound bed during NPWT. Three different …

Cefazolin Concentration in Surgically Created Wounds Treated with Negative Pressure Wound Therapy Compared to Surgically Created Wounds Treated with Nonadherent Wound Dressings
… tissue samples collected from surgically created wounds treated with negative pressure wound therapy to those collected from surgically created wounds treated with nonadherent dressings. The study design was a prospective, controlled, experimental study. The animal population included 12 female …

Development of a simplified negative pressure wound device
… For these reasons, a successful, chronic wound treatment, known as negative pressure wound therapy (NPWT), has not been readily used, although many patients would benefit. Aiming to expand this therapy, the viability of inexpensive, purely mechanical simplified negative pressure wound …

Continuous High-Pressure Negative Suction Drain: New Powerful Tool for Closed Wound Management: Clinical Experience
… performed, there still are difficult wound complications, such as seroma formation, wound margin necrosis, delayed wound healing, and even flap failures. The negative-pressure wound therapy has been described in detail in the literature to assist open chronic/complex wound closure in …

UNDERSTANDING ANATOMICAL PERFUSION AND STRATEGIES TO OPTIMIZE VASCULARITY IN FREE TISSUE TRANSFER FOR AUTOLOGOUS BREAST RECONSTRUCTION USING THE DEEP INFERIOR EPIGASTRIC ARTERY PERFORATOR (DIEP) FLAP
… of pretreatment of perforator flaps with negative pressure wound therapy to augment vascularity of perforator flaps prior to flap harvest. The vascular territories of individual perforator within hemi-DIEP flaps demonstrated variable patterns with unique patterns of perfusion. Concepts …
