The successful use of polylactide wound dressings for chronic lower leg wounds: A retrospective analysis.

Chronic wounds are a challenging medical entity for patients, medical professionals and healthcare systems. Frequently, patients present themselves to wound specialists after months or even years of unsuccessful treatment. Recent developments have resulted in a multitude of different advanced wound dressings created to treat complex, chronic wounds, one of which is the polylactide dressing Suprathel. This study aimed at investigating the healing potential of Suprathel in chronic wounds and differentiating between old and "young", diabetic and non-diabetic chronic wounds. A prospective, multicentric, non-controlled intervention study was conducted, treating patients with chronic lower leg ulcers (>3 months) with Suprathel and assessing them weekly. Afterwards, a retrospective analysis was performed analysing the wound size initially, after 4 and after 8 weeks of treatment. Furthermore, a differentiation between diabetic and non-diabetic, and chronic wounds older and younger than 12 months, was assessed. A significant reduction in wound size was observed in the study population after 8 weeks of treatment. The effect size in the diabetic wound and the old chronic wound group even reached more than one, with the other groups still showing a large effect of the intervention. This study shows that Suprathel is a valuable tool in the armamentarium of a wound specialist. Not only could we show a positive effect on chronic wounds, we could even demonstrate a significant wound size reduction in chronic wounds of old and young, as well as diabetic wounds, with the treatment of older chronic and diabetic wounds yielding an even larger effect size. Further randomised, controlled studies are necessary to show the full potential of advanced wound dressing materials in large patient cohorts.

Porcine Xenograft and Epidermal Fully Synthetic Skin Substitutes in the Treatment of Partial-Thickness Burns: A Literature Review.

Background and Objectives: Porcine xenografts have been used successfully in partial thickness burn treatment for many years. Their disappearance from the market led to the search for effective and efficient alternatives. In this article, we examine the synthetic epidermal skin substitute Suprathel® as a substitute in the treatment of partial thickness burns. Materials and Methods: A systematic review following the PRISMA guidelines has been performed. Sixteen Suprathel® and 12 porcine xenograft studies could be included. Advantages and disadvantages between the treatments and the studies' primary endpoints have been investigated qualitatively and quantitatively. Results: Although Suprathel had a nearly six times larger TBSA in their studies (p < 0.001), it showed a significantly lower necessity for skin grafts (p < 0.001), and we found a significantly lower infection rate (p < 0.001) than in Porcine Xenografts. Nonetheless, no significant differences in the healing time (p = 0.67) and the number of dressing changes until complete wound healing (p = 0.139) could be found. Both products reduced pain to various degrees with the impression of a better performance of Suprathel® on a qualitative level. Porcine xenograft was not recommended for donor sites or coverage of sheet-transplanted keratinocytes, while Suprathel® was used successfully in both indications. Conclusion: The investigated parameters indicate that Suprathel® to be an effective replacement for porcine xenografts with even lower subsequent treatment rates. Suprathel® appears to be usable in an extended range of indications compared to porcine xenograft. Data heterogeneity limited conclusions from the results.

BurnCase 3D software validation study: Burn size measurement accuracy and inter-rater reliability.

OBJECTIVE: The aim of this study was to compare the accuracy of burn size estimation using the computer-assisted software BurnCase 3D (RISC Software GmbH, Hagenberg, Austria) with that using a 2D scan, considered to be the actual burn size. METHODS: Thirty artificial burn areas were pre planned and prepared on three mannequins (one child, one female, and one male). Five trained physicians (raters) were asked to assess the size of all wound areas using BurnCase 3D software. The results were then compared with the real wound areas, as determined by 2D planimetry imaging. To examine inter-rater reliability, we performed an intraclass correlation analysis with a 95% confidence interval. RESULTS: The mean wound area estimations of the five raters using BurnCase 3D were in total 20.7±0.9% for the child, 27.2±1.5% for the female and 16.5±0.1% for the male mannequin. Our analysis showed relative overestimations of 0.4%, 2.8% and 1.5% for the child, female and male mannequins respectively, compared to the 2D scan. The intraclass correlation between the single raters for mean percentage of the artificial burn areas was 98.6%. There was also a high intraclass correlation between the single raters and the 2D Scan visible. CONCLUSION: BurnCase 3D is a valid and reliable tool for the determination of total body surface area burned in standard models. Further clinical studies including different pediatric and overweight adult mannequins are warranted.

What's in a Name? Recent Key Projects of the Committee on Organization and Delivery of Burn Care.

The Committee for the Organization and Delivery of Burn Care (ODBC) was charged by President Palmieri and the American Burn Association (ABA) Board of Directors with presenting a plenary session at the 45th Meeting of the ABA in Palm Springs, CA, in 2013. The objective of the plenary session was to inform the membership about the wide range of the activities performed by the ODBC committee. The hope was that this session would encourage active involvement within the ABA as a means to improve the delivery of future burn care. Selected current activities were summarized by key leaders of each project and highlighted in the plenary session. The history of the committee, current projects in disaster management, regionalization, best practice guidelines, federal partnerships, product development, new technologies, electronic medical records, and manpower issues in the burn workforce were summarized. The ODBC committee is a keystone committee of the ABA. It is tasked by the ABA leadership with addressing and leading progress in many areas that constitute current challenges in the delivery of burn care.

The potential impact of wrong TBSA estimations on fluid resuscitation in patients suffering from burns: things to keep in mind.

INTRODUCTION: Accurate estimation of burn size is of critical importance, as it is incorporated in every resuscitation formula. The aim of this study was to investigate total burn surface area (TBSA) accuracy among burn specialists, evaluate the potential impact of incorrect evaluation on variations of resultant fluid resuscitation volumes and to discuss future possibilities to estimate or measure TBSA more precisely. METHODS: In a poll during two international burn meetings in 2010 and 2011 demonstrating three pictures of patients with different burn wound patterns and sizes we asked participants to estimate the total surface area burned in percentages. We then calculated resultant fluid volume differences based on established resuscitation formulas. RESULTS: In the polled 80 participants, the estimations for three patients demonstrated the following differences (DIF=MAX-MIN): for patient 1, 2 and 3 they were 22.5 (25-2.5), 16.5 (20-3.5) and 31.5 (40-8.5) %TBSA, respectively. Based on these differences we calculated the volume differences for patients 1,2 and 3, which were 1080ml (Cincinnati Formula), 5280ml (Parkland Formula) and 2016ml (Cincinnati Formula), respectively. CONCLUSIONS: The analysis showed high deviations of total body surface area among participants, also resulting in large variations of initial fluid resuscitation volumes. One option to address estimation variances is to perform more accurate assessments; also incorporating new technologies aiding to improve the quality of body surface estimations and related decisions.
