Objectives/Interrogation: The most common diagnostic method for the evaluation of burn depth is the clinical inspection and the tactile examination. The conventional histological analysis is still considered the gold standard, but due to its invasiveness and time expenses it is not suitable in acute diagnostics.

Currently, Hyperspectral Cameras with specially programmed software are occasionally used to support the burn depth evaluation. It needs to be determined to what extent these devices can facilitate and objectify the assessment of burn depth, especially in hand burns.

Methods: The physical measurement principle of the so-called remissions spectroscopy is to irradiate the burn wound with white light and to evaluate the reflected light with a special spectral camera unit.

In the superficial wound layers (up to 6 mm deep), the light is reflected differently due to the inhomogeneity of the tissue. Remitted light contains information about tissue structures and especially tissue damage.

Using a proprietary software, the parameters tissue oxygenation (sO2), tissue hemoglobin index (THI) and near-infrared perfusion (NIR perfusion) are recorded. A recently available advanced software is able to extract even more accurate data from the recorded spectra.

The procedure is non-contact, unburdening for the patient and in the current implementation quickly and easily applicable.

Results and Conclusions: In selected cases, the spectral camera is used to aid in the evaluation of burn wounds.

With ongoing data acquisition and now extended software, certain correlations can already be deduced from the recordings and linked to a "burn index".

Burns of a deeper degree clearly show lower levels in the superficial and in the deep blood circulation.

Ideally, the use of these spectral cameras should not only make it possible to objectify the evaluation, but in addition, the deeper wound layers can also be assessed.

This is particularly important in the differentiation of deeper burns and differently affected burn degrees, so that sufficient surgical treatment can be initiated early on.

Currently, it is important to optimize the respective reference values of the individual burn degrees for an objectified assessment.
