NPWT

BACKGROUND: We encountered a case of infected soft tissue defect of the fingertip treated using negative pressure wound therapy (NPWT). The development of NPWT was started in the early 1990s, and it is a relatively new treatment method included in insurance coverage in Japan in 2010. NPWT is used for intractable wounds; some reports have examined its use on infected wounds. However, to the best of our knowledge, no study has examined its use on infected fingertip wounds. METHODS: A patient with an infected soft tissue defect in the fingertip whose epithelialization period was prolonged despite continued antibiotic therapy was treated using NPWT in combination...

Background: Surgical site complications (SSCs) are common, yet preventable hospital-acquired conditions. Single-use negative pressure wound therapy (sNPWT) has been shown to be effective in reducing rates of these complications. In the era of value-based care, strategic allocation of sNPWT is needed to optimize both clinical and financial outcomes. Materials and Methods: We conducted a retrospective analysis using data from the Premier Healthcare Database (2017-2021) for 10 representative open procedures in orthopedic, abdominal, cardiovascular, cesarean delivery, and breast surgery...

BACKGROUND: NPWT has been used to treat various wounds. Scant evidence exists on the use of custom-made NPWT for infected wounds. NPWT dressings promote wound healing by increasing local blood flow and antibiotic concentration, and by removing exudates from the wound. OBJECTIVE: To report the use of custom-made NPWT dressings to manage complex infected wounds of the lower limb. MATERIALS AND METHODS: The authors retrospectively reviewed the records of 43 patients with complex infected wounds of the lower limb treated with debridement and low-cost, custom-made NPWT dressing connected to wall suction from January 1, 2018 to December 31, 2020, at PSG Medical College Hospital, Coimbatore, India...

BACKGROUND: NPWTi-d of a topical wound solution has been shown to benefit healing in a variety of wound types. This therapy has traditionally been applied via a standard ROCF-V. In 2017, a new ROCF-CC was introduced at the practice of the authors of the current manuscript for adjunctive management of patients with wounds with thick exudate and/or nonviable tissue and in cases in which surgical debridement is not available or not appropriate. OBJECTIVE: To compare the efficacy of NPWTi-d with ROCF-CC dressing (treatment) vs NPWTi-d with ROCF-V dressing (control)...

Negative pressure wound therapy (NPWT) is extensively employed in clinical settings to enhance the healing of wounds. Despite its widespread use, the molecular mechanisms driving the efficacy of NPWT have not been fully elucidated. In this study, skin wound-healing models were established, with administration of NPWT. Vimentin, collagen I, and MMP9 of skin tissues were detected by immunofluorescence (IF). Gene expression analysis of skin wound tissues was performed by RNA-sequencing (RNA-seq). Protein expression was assayed by a western blotting or IF assay, and mRNA levels were quantified by quantitative PCR...

Introduction: Negative pressure wound therapy (NPWT) alone or with the addition of a split-thickness skin graft (STSG) are 2 reconstructive options available after surgical excision of axillary hidradenitis suppurativa (HS). The aim of this study was to retrospectively examine patients undergoing these treatments and to assess clinical and patient-related outcome measures. Methods: A single-centre, retrospective analysis was conducted, evaluating surgical excision of axillary HS, with STSG and NPWT, or NPWT alone...

Burn injuries are the fourth most common type of trauma worldwide, after traffic injuries, falls and interpersonal violence. Vascular endothelial growth factor (VEGF) is one of the most critical proangiogenic factors. Failure in angiogenesis is often associated with chronic, non-healing wounds. This study aimed to compare the effect of sterile gauze with normal saline (NaCl) 0.9%, intermittent negative pressure wound therapy (NPWT), continuous NPWT, and silver sulfadiazine dressing on increasing VEGF and angiogenesis in deep dermal burn injury...

Background : Negative pressure wound therapy (NPWT) is an intensely investigated topic, but its mechanism of action accounts for one of the least understood ones in the area of wound healing. Apart from a misleading nomenclature, by far the most used diagnostic tool to investigate NPWT, the laser Doppler, also has its weaknesses regarding the detection of changes in blood flow and velocity. The aim of the present study is to explain laser Doppler readings within the context of NPWT influence. Methods : The cutaneous microcirculation beneath an NPWT system of 10 healthy volunteers was assessed using two different laser Dopplers (O2C/Rad-97® )...

SIGNIFICANCE: Since the introduction of the first commercial negative pressure wound therapy (NPWT) system nearly three decades ago, several key technological innovations have led to wide adoption of the therapy. This is a review of the history and innovation of commercial NPWT systems for adjunctive management of open wounds. RECENT ADVANCES: Technical modifications have broadened NPWT options to include innovative dressing interfaces, tubing configurations, power sources, capability of topical wound solution instillation or irrigation, canister versus canister-free configurations, smart technology, and disposable versus larger reusable therapy units...

OBJECTIVE: Negative pressure wound therapy (NPWT) and oxidized regenerated cellulose (ORC)/collagen/silver-ORC (OCSO) dressings have individually demonstrated effectiveness in supporting wound healing, but few studies have examined their combined use. This retrospective data analysis compared wound outcomes following outpatient NPWT with and without OCSO dressings. APPROACH: A search of de-identified records from the U.S. Wound Registry resulted in 485 cases of wounds managed with NPWT with OCSO dressings...

BACKGROUND: Surgical site infections (SSIs) are a common cause of morbidity after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal malignancy. Negative pressure wound therapy (NPWT) has been proposed as a method to reduce the rates of SSIs; however, there is paucity in the literature on the efficacy in this population. The goal of this study was to determine whether routine use of NPWT in patients undergoing CRS/HIPEC could reduce the risk of developing SSI...

Negative pressure injury is one of the auxiliary methods of treating diabetes foot ulcers. It has been shown to be superior to conventional techniques in randomized controlled trials (RCTs). Nevertheless, the results of observational research are still scarce. A systematic review of RCTs and observations was carried out to evaluate the effectiveness and security of negative pressure wound therapy (NPWT) treatment for diabetes foot ulcers. Three English e-databases have been found for NPWT research. The meta-analyses of the comparative studies provided point estimates of results...

Introduction Negative-pressure wound therapy (NPWT) has been used for decades as an established treatment modality for complex wounds, now commonplace in hospitals and various clinical and outpatient settings. Several studies have noted improved healing outcomes with this device, but the current state of literature is in debate on both clinical and economic effectiveness. The use of NPWT can become expensive, largely because of the complexity of wounds and the need for outpatient management, from which a majority of the benefit is derived...

A meta-analysis was conducted to comprehensively explore the effects of platelet-rich plasma (PRP) combined with negative pressure wound therapy (NPWT) in treating patients with chronic wounds. Computer searches were conducted, from database infection to November 2023, in EMBASE, Google Scholar, Cochrane Library, PubMed, Wanfang and China National Knowledge Infrastructure databases for randomized controlled trials (RCTs) on the use of PRP combined with NPWT technology for treating chronic wounds. Two researchers independently screened the literature, extracted data and conducted quality assessments according to the inclusion and exclusion criteria...

BACKGROUND: Each year, millions of Americans develop truncal pressure ulcers (PUs) which can persist for months, years, or until the end of life. Despite the negative impact on quality of life and escalating costs associated with PUs, there is sparse evidence supporting validated and efficacious treatment options. As a result, treatment is based on opinion and extrapolation from other wound etiologies. The ideal reconstructive plan maximizes the patient's nutritional status, incorporates the basic tenets of wound bed preparation (debridement, offloading, proper moisture balance, reduction of bacterial burden), and employs diagnostics to guide therapeutic intervention...

BACKGROUND: Vascular surgical site infections have been reported with an overall incidence of 5-10% for patients undergoing arterial interventions and as high as 10-20% for lower-limb bypass grafting procedures. Given that vascular surgery patients are known to be at a higher risk of postoperative wound infections and other complications, our objective was to evaluate a potential method to reduce such complications. This study compares the rate of wound healing complications between incisional negative pressure wound therapy (NPWT) and conventional dressings in vascular surgery patients with infra-inguinal incisions...

Background : Distal lower extremity reconstruction is challenging. This study aims to propose a protocol for the treatment of traumatic soft tissue defects. The key concept is to combine the surgical armamentarium of the reconstructive surgeon with the advantages provided by hyperbaric oxygen therapy. Methods : This retrospective study analyzed data of 57 patients affected with unilateral or bilateral lower extremity trauma distal to the knee and involving soft tissues with no indication of immediate reconstruction between 2010 and 2021...

BACKGROUND: Negative Pressure Wound Therapy (NPWT) is a therapeutic technique of applying sub-atmospheric pressure to a wound to reduce inflammation, manage exudate, and promote the formation of granulation tissue. It aims to optimise the natural physiological processes of wound healing for more effective recovery, and NPWT has emerged as a promising alternative to traditional dressings. METHODS: The protocol followed in the study was prospectively registered. Appropriate search terms and Boolean operators were used to search electronic databases for relevant articles...

Negative pressure wound therapy (NPWT) is effective in repairing serious skin injury. The dressing used in the NPWT is important for wound healing. In this paper, we develop biodegradable amphiphilic polyurethanes (PUs) and fabricate the PUs into sponges as wound dressings (Bi@e ) with Janus pore architectures for NPWT. The Bi@e is adaptive to all the stages of the wound healing process. The Janus Bi@e sponge consists of two layers: the dense hydrophobic upper layer with small pores provides protection and support during negative pressure drainage, and the loose hydrophilic lower layer with large pores absorbs large amounts of wound exudate and maintains a moist environment...
