Abstract

Research over the last 50 years has led to significant improvements in outcomes for burn victims. Advances in infection control, attenuation of the hypermetabolic response, and new improved surgical approaches have led to decreased morbidity and mortality. Early wound excision eliminates the devitalized tissue, which is the main reservoir for pathogen propagation. Immediate autografting reestablishes the natural barrier of the skin, which blocks pathogen access to the host. Advances in burn care have increased treatment options for patients with devastating injuries presenting with multiple comorbidities. Over the last 20 years, negative pressure assisted wound therapy (NPWT) has shown to improve wound management and healing as well as decrease the length of recovery in burn patients. As NPWT applications evolve, the development of negative pressure wound therapy with instillation and dwell time (NPWTi-d) for the management of complex and infected wounds has proven vital for patient care.

We present the case of a 68-year-old male patient presenting with a three-day-old third-degree burn wound spanning 46% of the total body surface area (TBSA). After the infected wound was treated unsuccessfully with the standard of care (excision, debridement, and grafting), the team utilized NPWTi-d in order to mitigate the infection and promote the formation of granulation tissue, leading to the successful grafting of the burn wound.

NPWTi-d was a useful adjunct in treating and stimulating wound healing in a complex patient. This is the first case report of its kind, utilizing a whole-body vacuum assisted closure (VAC) with NPWTi-d, with successful results showing a decreased bacterial burden, decreased morbidity and mortality, and patient wound closure.

Negative Pressure Wound Therapy With Instillation (NPWTi) Better Reduces Post-debridement Bioburden in Chronically Infected Lower Extremity Wounds Than NPWT Alone.

S G Goss, J A Schwartz, F Facchin … (2012)

An overabundance of bacteria in the chronic wound plays a significant role in the decreased ability for primary closure. One means of decreasing the bioburden in a wound is to operatively debride the wound for wound bed optimization prior to application of other therapy, such as Negative Pressure Wound Therapy (NPWT). We undertook a prospective pilot study to assess the efficacy of wound bed preparation for a standard algorithm (sharp surgical debridement followed by NPWT) versus one employing sharp surgical debridement followed by Negative Pressure Wound Therapy with Instillation (NPWTi).

Negative Pressure Wound Therapy With Instillation: Review of Evidence and Recommendations.

Paul J. Kim, Christopher Attinger, Olayinka Olawoye … (2015)

Negative pressure wound therapy with instillation (NPWTi) and dwell time is an adjunctive treatment modality for selected complex wounds. Because of the greater amount of research now available, a multidisciplinary expert panel comprising the fields of podiatry, plastic and general surgery, burn treatment, infectious diseases, and orthopedics was convened on July 11, 2015, to produce a summary of the data and recommendations on the use of NPWTi. The panel members each reviewed available published literature on NPWTi in the PubMed, Cochrane, and Google Scholar databases from 1 January 2012 up until 20 July 2015 using the string search term negative pressure wound therapy instillation provided by the panel moderator; there were no restrictions on the language or type of publication. Panel members discussed their experiences and worked to reach consensus on several predefined topics. NPWTi was found to be most appropriate for properly selected complex hosts or wounds such as patients with multiple comorbidities, patients with an American Society of Anesthesiology Classification ≥ 2, severe traumatic wounds, diabetic foot infections, and wounds complicated by invasive infection or extensive biofilm. NPWTi should not be used routinely to treat simple wounds or hosts without comorbidities.There is evidence that when NPWTi is added to standard of care in properly selected cases it provides better overall clinical outcomes than standard of care alone, even when including NPWT. Based on published evidence and panel member experience, the Panel recommends a dwell time - fluid briefly instilled into the wound and allowed to diffuse for a user-specified time - of 10-20 minutes followed by 2-4 hours of negative pressure at -125 mmHg, although larger wounds may need times of up to 6 hours. Normal saline (0.9%) is the preferred solution for NPWTi, except in special situations. NPWTi with dwell time is an adjunct to other standard principles of appropriate wound assessment and treatment (e.g., debridement, pressure offloading, systemic antibiotic therapy, vascular assessment and revascularization when needed, or glycemic control).

A prospective randomized controlled trial comparing negative pressure dressing and conventional dressing methods on split-thickness skin grafts in burned patients.

Kiran Petkar, Prema Dhanraj, Paul M Kingsly … (2011)

Split-thickness skin grafting (SSG) is a technique used extensively in the care of burn patients and is fraught with suboptimal graft take when there is a less-than-ideal graft bed and/or grafting conditions. The technique of Negative Pressure Dressing (NPD), initially used for better wound healing has been tried on skin-grafts and has shown to increase the graft take rates. However, comparative studies between the conventional dressing and vacuum assisted closure on skin grafts in burn patients are unavailable. The present study was undertaken to find out if NPD improves graft take as compared to conventional dressing in burns patients. Consecutive burn patients undergoing split-skin grafting were randomized to receive either a conventional dressing consisting of Vaseline gauze and cotton pads or to have a NPD of 80 mm Hg for four days over the freshly laid SSG. The results in terms of amount of graft take, duration of dressings for the grafted area and the cost of treatment of wound were compared between the two groups. A total of 40 split-skin grafts were put on 30 patients. The grafted wounds included acute and chronic burns wounds and surgically created raw areas during burn reconstruction. Twenty-one of them received NPD and 19 served as controls. Patient profiles and average size of the grafts were comparable between the two groups. The vacuum closure assembly was well tolerated by all patients. Final graft take at nine days in the study group ranged from 90 to 100 per cent with an average of 96.7 per cent (SD: 3.55). The control group showed a graft take ranging between 70 and 100 percent with an average graft take of 87.5 percent (SD: 8.73). Mean duration of continued dressings on the grafted area was 8 days in cases (SD: 1.48) and 11 days in controls (SD: 2.2) after surgery. Each of these differences was found to be statistically significant (p<0.001). Negative pressure dressing improves graft take in burns patients and can particularly be considered when wound bed and grafting conditions seem less-than-ideal. The negative pressure can also be effectively assembled using locally available materials thus significantly reducing the cost of treatment. Copyright © 2011 Elsevier Ltd and ISBI.
