This study reviews free tissue transfer (FTT) surgery for both acute wound and reconstructive scar management of burn injuries at a UK burns unit over a 10-year period. Thirty eight patients underwent 46 FTTs, or free flaps, as part of their burn injury pathway. For the cohort of patients, there was one flap failure, which occurred for a secondary scar reconstruction. It is noted that FTT was successful for all seven acute or primary interventions. Anterolateral thigh flap was the most frequently performed (57%); followed by parascapular flaps (22%) of which 43% were pre-expanded. A method of pre-expansion for neck contractures and a novel technique of anchoring this flap to the pre-tracheal fascia are described here. This can provide the patient with good neck contouring by using the capsule to hitch the flap into a good position. It is clear that further work is required to study the prevention of hypertrophic scarring that can occur at the interface between flap and adjacent skin, where occurrence rate in this cohort was 17%. It is proposed that FTT now provides a viable solution both to the coverage of complex burn wounds and to the revision of scar contractures. Consensus over an FTT protocol for the primary management of open burn wounds is seen as the logical next step for this surgical intervention. [ABSTRACT FROM AUTHOR]

Thermal disease presents a major burden to individual patient morbidity, healthcare cost as well as to over all economy. Burns also also represent a significant per-patient utlilisation of finite healthcare resources. Secondary complications in these patients, such as multiple drug resistant organisms, may have a devastating effect. Laser surgery has recently come of age as an optimal tool in the secondary reconstruction of burn injury, that is able to simultaneously address significant sheet scar tightness, hypertrophic, atrophic, and keloid complications, pruritus, microstomia, ectropion, skin graft honeycombing, and improve range of movement whilst reducing the risk of infection to <1%. Yet, cutaneous laser surgery is often underutilised due to the perceived concerns about the sustainability of a new service with relatively high startup cost. We present a dual methodology to explore this concern: an evidence-based background review of the last 5 years of current best evidence, and a 22-year cost-analysis comparison at an established, high volume UK Centre of reconstructive surgery. We report that fiscal viability for laser surgery services for secondary burn reconstruction is supported by: level 2 (one systematic review) level 4 evidence (2 studies) and level 5 evidence (expert reports). Evidence over 22 years from an established super-regional NHS laser centre shows that introduction of this service led to sustained and substantial cost saving, producing excellent surgical results at a fraction of the cost of traditional surgery. Analysis of the potential dollar-effect of these advantages to the general population supports state investment in expertise and capital equipment as a medium to long-term cost saving strategy, which may also aid re-integrating patients into the workforce making a meaningful contribution to the economy.

Abstract: Background: The use of topical negative pressure (TNP) dressings with dermal regeneration template (DRT), Integra, has improved outcomes and simplified aftercare. Previous clinical studies have suggested accelerated vascularisation; with a reduction in the duration of the 1st stage after the application of Integra, from 2 to 4 weeks to as little as 4 days, but with no histological evidence. However, histological studies, without TNP, have shown that vascularisation occurs between the second and the fourth week. This study set out to examine histologically the rate of DRT neovascularisation when combined with TNP. Methods: Eight patients with nine reconstruction sites were enlisted. Unmeshed Integra and fibrin sealant to promote adherence were used. TNP was applied for the duration between the 1st and the 2nd stages. Patients underwent serial biopsies on days 7, 14, 21 and 28 post-application. The biopsies were stained with H&E and endothelial markers CD31 and CD34. Template vascularisation was assessed as a percentage of the template depth in which patent, canalised vascular channels could be demonstrated. Results: The median percentage of the template depth which demonstrated canalised channels was 0%, 20%, 61% and 80% for days, 7, 14, 21 and 28, respectively. Conclusion: The application of TNP dressings to dermal templates can reduce shearing forces, restrict seroma and haematoma formation, simplify wound care and improve patient tolerance. However, this study could not demonstrate that TNP accelerates neovascularisation as verified by the presence of histologically patent vascular channels. [ABSTRACT FROM AUTHOR]

Abstract: Pressure garments have been used prophylactically and to treat hypertrophic scars, resulting from serious burns, since the early 1970s. They are custom-made from elastic fabrics by commercial producers and hospital staff. However, no clear scientifically established method has ever been published for their design and manufacture. Previous work identified the most commonly used fabrics and construction methods for the production of pressure garments by hospital staff in UK burn units. These methods were evaluated by measuring pressures delivered to both cylinder models and to human limbs using I-scan® pressure sensors. A new calibration method was developed for the I-scan® system to enable measurement of low interface pressures to an accuracy of ±2.5mmHg. The effects of cylinder/limb circumference and pressure garment design on the pressures exerted were established. These measurements confirm the limitations of current pressure garment construction methods used in UK hospitals. A new method for designing pressure garments that will exert specific known pressures is proposed and evaluated for human thighs. Evaluation of the proposed design method is ongoing for other body parts. [Copyright &y& Elsevier]
