[Objective burn depth assessment of hand burns].

The depth assessment of thermal wounds is subject to many variables. Therefore, technical systems are increasingly being used to determine severity. Particularly hand burns can have clinically relevant consequences in terms of function and aesthetic appearance. Hence, a secure assessment for an adequate treatment is necessary.Technical analyzes such as Hyperspectral Imaging, Laser-Doppler-Imaging or Laser-Speckle-Imaging are intended to simplify and objectify the examination by helping to determine the necessary depth of necrectomy and thus to define the skin transplantation area. Furthermore, the diverse technical devices are to improve the functional result, reduce the severity of scarring and cosmetic complaints, and facilitate the evaluation of inexperienced personnel in the field of burn medicine.Therefore, various technical approaches have been pursued, which are largely based on optical principles. The respective devices are not yet used in the standard diagnosis of burn wounds.In future studies it will be necessary to determine an algorithm for the measurement intervals based on the wound dynamics and to evaluate which methodology is superior to the specificity and sensitivity.
