New technologies in the field of burn wound and scar assessment are continually being evaluated. Accurate estimation of total body surface area (TBSA) burn wound is of paramount importance in fluid resuscitation to prevent complications which are associated with morbidity and mortality. Estimating the TBSA is performed by a multitude of different methods, however a gold standard would be ideal. The aim of this study was to compare the estimation of burned TBSA% between 3D photography by Panasonic FZ-M1 Toughpad in conjunction with WoundCare Lite software and expert opinion volunteered by burns doctors. ⋯ This study has demonstrated that the wound mapping software WoundCare Lite in conjunction with the Panasonic FZ-M1 Toughpad 3D camera compares well with expert opinion in determining burn surface area on a mannequin. Further research is needed to establish whether this is the case in burns on patients in an acute setting.

Methylene blue reduces progression of burn and increases skin survival in an experimental rat model.
Following burn, increased nitric oxide (NO) combine with superoxide anion forming peroxynitrite. Methylene blue (MB) has NO blocking and antioxidant effects. Male Wistar rats (250g) were burned bilaterally in dorsum with a comb metal plate heated inside boiling water and applied during 30s, creating four rectangular 10×20mm full-thickness burned areas separated by three 5×20mm unburned interspaces (stasis zone). 30 rats were randomized into three groups (n=10): treated groups received one dose of intraperitoneal (IP) MB injections (2mg/kg), one or six hours after injury, and control group received saline. ⋯ Interspace's NOx increased in both MB groups (P=0.0130) with no difference in burned areas. No MDA difference was observed. IP MB injection one or six hours after injury reduced necrosis progression in stasis area in the rat comb burn model suggesting an antioxidant effect reducing oxidative stress.
