A prolonged and fulminant inflammatory state, with high levels of pro- and anti-inflammatory mediators, is seen after extensive thermal injury. Blood purification techniques including plasma exchange, continuous venovenous hemofiltration, and adsorbing membranes have the potential to modulate this response, thereby improving outcomes. This article describes the scientific rationale behind blood purification in burns and offers a review of literature regarding its potential application in this patient cohort.

Free tissue transfer is a rarely indicated procedure in burns. However, in well selected cases it may play a pivotal role in optimizing outcomes in both primary and secondary burn reconstruction. We undertook a systematic review, based on the PRISMA statement for systematic reviews, of all published literature relating to the use of free flaps in acute burns and in secondary reconstructive procedures. ⋯ We present the indications, timing, complications and failure rates for free flaps in primary and secondary reconstruction based on the available literature. We also provide a list of the various free flap options for the commonest sites undergoing reconstruction following burns. Finally an algorithm to ensure optimal success of free flaps when used in primary and in secondary burn reconstruction is presented.

The standard of care for deep burns is autologous split thickness skin grafting. Although adequate to resurface a deep wound, the resulting skin is chronically abnormal. The purpose of this study was to describe the experience of patients with split thickness skin grafts to help guide future investigations related to skin regeneration. ⋯ Eight male patients and four female patients 20-62 years old ranging 2-29 months post-skin grafting were enrolled in the study. The most significant concerns voiced by patients were identified and organized into five themes: (1) a new normal, (2) split thickness skin graft symptoms, (3) appearance of new skin, (4) coping, and (5) participation in future clinical trials. Participants reported that the abnormalities related to their split thickness skin grafts were significant enough that they would be willing to participate in a future clinical trial investigating new cell-based therapies.

Traditional wound dressings, including cotton gauze, absorbent pads and bandages, can cause trauma and pain to wounds during dressing changes, leading to a variety of physical and psychosocial sequelae. The aim of this study was to adapt an in vitro model of adherence to evaluate the effects of various methods to theoretically reduce the adherence of wound dressings. Gelatin in liquid form was cast onto poly(ethylene terephthalate) (PET) fabric and allowed to solidify and progressively dry to simulate wound desiccation in the clinical setting. ⋯ As a long-term strategy for decreasing adherence, a thin layer of polyacrylamide (PAM) hydrogel was deposited onto PET fabric via UV irradiation. This resulted in a much lower peeling energy without severely compromising fabric flexibility. This hydrogel layer could also serve as a reservoir for bioactive and antimicrobial agents which could be sustainably released to create a microbe-free microenvironment for optimized wound healing.
