AbstractThe estimation of burn depths is still a challenge, and even experienced surgeons often fail. In search of an objective method for differentiation between deep- and partial-thickness burns, we investigated the use of orthogonal polarization spectral (OPS) imaging to visualize the microcirculation in burn wounds. Twenty-seven burned patients were included in the study, 81 burn areas were investigated at day 1 and 4 post burn. The final therapy was compared with the therapy that would have been carried out as a consequence of the OPS imaging result. The patients were treated conservatively with dressings or surgically with necrectomy and split skin grafts. A comparison of the estimation of the burn depths of OPS imaging with the final therapy showed a correlation of 76.5%, about 5% less than the clinical assessment. It has proved a useful tool in particular for the prognosis as to whether the burn will heal spontaneously within 14 days or not. The presented OPS-Imaging device provides additional qualitative and quantitative information about the perfusion of the skin and therefore facilitates decisions about the follow on therapy. It is not an alternative to an experienced burn surgeon but provides important additional information.
