pressure ulcer,NPWT

Kristian Arvesen, Camilla Bak Nielsen, Karsten Fogh
Negative pressure wound therapy (NPWT) and intermittent pneumatic compression (IPC) have traditionally been used in patients with chronic complicated non-healing wounds. The aim of this study (retrospective case series) was to describe the use of NPWT in combination with IPC in patients with a relatively short history (2-6 months) of ulcers. All wounds showed improved healing during the treatment period with marked or moderate reduction in ulcer size, and granulation tissue formation was markedly stimulated...

Negative pressure wound therapy (NPWT) consists in applying subatmospheric pressure to a wound that is sealed off by a specially designed dressing and connected by a tube to a suction pump and drainage collection system. Skin defects are extremely common in orthopaedic and trauma surgery. NPWT is valuable across a range of indications. Proven effects include an increase in blood flow, stimulation of angiogenesis, and a decrease in wound surface area. NPWT can be used to treat post-traumatic and surgical wounds, burns, and chronic wounds such as pressure sores and ulcers...

Complex pressure ulcer wound sites often present with a wide scope of barriers to healing ranging from high colonization of multi-drug-resistant pathogens to tortuous internal anatomy which make the wound recalcitrant to traditional wound care including standard negative pressure wound therapy (NPWT). Negative pressure wound therapy with instillation (NPWTi-d) provides an opportunity to manage and heal wounds with indications not met by standard NPWT such as cavitating wounds with complex undermining and tunneling...

Negative-pressure wound therapy (NPWT) applies vacuum pressure to a wound bed sealed by an adhesive dressing to improve wound healing. A cleansing solution, often antibiotics or saline, may be instilled into the wound bed concurrently and removed via suction, thus enhancing the therapeutic effect. The therapeutic effect results from improved blood flow and removal of inflammatory factors. Since 1995, the FDA has approved NPWT for medical use. Since then, this technology has been applied to different types of wounds, including diabetic and decubitus ulcers and postsurgical incisional wounds...

Objective: Evaluate the therapeutic properties of a peroxy pyruvic acid (PPA)-containing topical anti-infective in a human ex-vivo model that replicates the natural conditions of a human chronic wound. Approach: Wound material was extracted from patients with nonhealing diabetic ulcers, venous stasis ulcers, and arterial wounds. Microbial species were identified, and wound colonization was quantified. Extracted samples were then exposed to a PPA-containing topical anti-infective as an instillation solution with negative pressure wound therapy NPWT at concentrations of 1,000, 1,500, or 2,500 ppm for a period of 1, 5, or 10 min to determine the effect of exposure on isolated pathogens, including effect on proteins...

OBJECTIVE: Negative-pressure wound therapy (NPWT) has become a common wound care treatment modality for a variety of wounds. Several previous studies have reported that NPWT increases blood flow in the wound bed. However, NPWT might decrease tissue oxygenation in the wound bed because the foam sponge of NPWT compresses the wound bed under the influence of the applied negative pressure. Adequate tissue oxygenation is an essential consideration during diabetic foot management, and the foot is more sensitive to ischemia than any other region...

Exact data regarding the clinical role of negative pressure wound therapy (NPWT) for wound care in a specific country are not available. Thus, we analysed the use of NPWT in hospitalised patients in Germany. Detailed lists of all hospitalised cases treated with NPWT in Germany for each of the years from 2005 to 2014 were obtained from the Federal Statistical Office, as well as lists of the 15 most frequent principal and additional diagnoses documented with NPWT in 2014. Within the 10-year time period of the study, the number of cases treated with NPWT increased by 349%, from 37 053 in 2005 to 129 269 in 2014...

Major wound complications of the extremities, following wide tumor resection and reconstruction for soft-tissue sarcomas (STSs), remain a challenge for limb-sparing surgery. Furthermore, STSs with ulceration or impending ulceration predispose patients to an increased risk of post-operative infection. The present study was conducted to assess the efficacy of negative pressure wound therapy (NPWT) in preventing wound complications associated with surgical treatment of STSs with ulceration or impending ulceration, in patients treated between February 2012 and January 2013...

Current embodiments of negative pressure wound therapy (NPWT) create a hermetically sealed chamber at the surface of the body using polyurethane foam connected to a vacuum pump, which is then covered by a flexible adhesive drape. Commercially available NPWT systems routinely use flexible polyethylene films that have a sticky side, coated with the same acrylate adhesives used in other medical devices such as ECG leads and grounding pads. Severe reactions to the acrylate adhesives in these other devices, although uncommon, have been reported...

OBJECTIVE: Diabetic ulcers are the most common foot injuries leading to lower-extremity amputation and the most common cause of non-traumatic lower extremity amputations in the industrialised world. Approximately 85% of all diabetes-related lower-extremity amputations are preceded by foot ulcers. When foot ulcers develop despite preventive measures, early and appropriate treatment should be initiated to help reduce the burden of diabetes-related amputations. Recent advances now offer these patients a regenerative process of restoring the wound with human integument by replacing damaged or missing tissue with similar tissue rather than scar formation...

Diabetic foot wounds present a great challenge to surgeons. They are difficult to heal and are a significant risk factor for non-traumatic foot amputation besides being a huge financial burden. NPWT systems commercially available (VAC™ system, KCI Inc., USA) are costly precluding widespread use. To determine whether negative-pressure wound therapy (NPWT) would afford quicker wound recovery as compared to saline-moistened gauze in the treatment of diabetic foot wounds. Sixty patients were randomized into either the experimental NPWT group or conventional dressing group (control)...
