Laser Doppler imaging as a tool in the burn wound treatment protocol

INTRODUCTION: The main treatment of burns is early excision of injured tissues. AIM: To compare two different methods of examination of burned patients: clinical burn depth examination (CDE) and laser Doppler imaging (LDI). MATERIAL AND METHODS: A prospective randomized study of 57 burn patients treated in 2009–2011 was carried out. The burned patients were randomized into a CDE group and an LDI group. The CDE and LDI scan were performed 72 h after injury, with the second and third CDE and LDI scan on the 7(th) and 14(th) day after the burn. Age, sex, length of inpatient stay, cost of burn treatment, burn depth, cause and localization of the burns were analyzed between the two groups. RESULTS: Fifty-seven patients were treated during 2 years. Thirty-two patients were in the CDE group and 25 patients were in the LDI group. Most of the patients were male (45 male vs. 12 female, p < 0.001). The age was similar between the males and the females (female: 46.4 ±16.9 years vs. male: 46.3 ±12.5 years; p = 0.11). The mean length of stay in hospital was significantly higher in the CDE group (47 ±34.4 day vs. 25 ±10.8 day; p = 0.005). The mean cost of treatment of burned patients was significantly higher in the CDE group. CONCLUSIONS: The length of stay and cost of treatment of burn patients depends upon early diagnosis of the deep burns and well-timed surgical treatment of burn wounds.
