“…Video microscopy was assessed by McGill et al [66] on patients admitted within 72 h after burn. Microvascular features were observed: ''intact or nearly intact dermal vasculature, progressing through to large amounts of capillary destruction and haemoglobin deposition in deep partial thickness injuries and complete destruction in full thickness injuries''.…”

“…While superficial and full-thickness burns types are relatively straightforward for clinicians to diagnose based on appearance, it is more difficult to categorize partial thickness burns (second-degree) that can fall in between the superficial or deep category. The accuracy of diagnosing these partial thickness burns by clinicians is typically 60-80% when the diagnosis is done several days after the burn injury [2][3][4]. However, when clinicians attempt to make the diagnosis within the first 24-48 hours of the occurrence of a burn, the accuracy of the diagnosis decreases to 50% [5].…”

“…LDI allows a clinician to visualize the spatial variation of perfusion, a key indicator of burn depths and eventual healing times. One of the issues associated with LDI, however, is that the analysis often measures relatively superficial blood flow, when quantitative, deeper analysis would be more informative to burn management, particularly with respect to differentiating superficial partial thickness burns from deep partial thickness burns [2,3]. In addition, for many of the LDI systems that are currently available, the laser is mechanically scanned over the patient for up to 5 minutes per image, resulting in movement artifacts and long data collection times for large surface area burns [3].…”

The detection of blood flow alone does not provide the definitive information regarding tissue health, particularly in the case of partialthickness burns [2,3]. LDI is less accurate when utilized within the first 24-48 hours of injury [5,11] and healing studies indicate that it is not until post-burn day 3 that severity assessment using LDI becomes significantly better than clinical assessment [5].…”

Accurate and timely assessment of burn wound severity is a critical component of wound management and has implications related to course of treatment. While most superficial burns and full thickness burns are easily diagnosed through visual inspection, burns that fall between these extremes are challenging to classify based on clinical appearance. Because of this, appropriate burn management may be delayed, increasing the risk of scarring and infection. Here we present an investigation that employs spatial frequency domain imaging (SFDI) and laser speckle imaging (LSI) as non-invasive technologies to characterize in-vivo burn severity. We used SFDI and LSI to investigate controlled burn wounds of graded severity in a Yorkshire pig model. Burn wounds were imaged starting at one hour after the initial injury and daily at approximately 24, 48 and 72 hours post burn. Biopsies were taken on each day in order to correlate the imaging data to the extent of burn damage as indicated via histological analysis. Changes in reduced scattering coefficient and blood flow could be used to categorize burn severity as soon as one hour after the burn injury. The results of this study suggest that SFDI and LSI information have the potential to provide useful metrics for quantifying the extent and severity of burn injuries.

To investigate the effectiveness of early depth assessment of local burns, the depth of which is difficult to assess with the naked eye, by dermoscopy. Design:The morphological findings of burn wounds were prospectively evaluated by dermoscopy and videomicroscopy. Prior to dermoscopic and videomicroscopic measurement, clinical assessment was performed. All patients received conservative treatment for 21 days after injury.Setting: A burns unit at a primary care hospital.Participants: Thirty-two patients with 41 intermediatedepth local burn wounds were included. Inclusion criteria were time to presentation greater than 24 hours after injury and total burn size greater than 1% and less than 10% of the total body surface area.Main Outcome Measures: Primary healing within 21 days (superficial partial thickness) and failure of primary healing within 21 days (deep partial thickness). The accuracy, sensitivity, and specificity of the assessment ac-cording to the algorithm proposed in this study were evaluated by dermoscopy, and the accuracy of the dermoscopic measurements was compared with videomicroscopic measurements and clinical assessments. Results:The results of dermoscopic measurements according to the proposed algorithm showed an accuracy of 93%, sensitivity of 86%, and specificity of 100%. The dermoscopic measurements were significantly more accurate compared with clinical assessment (P =.01).Conclusions: Dermoscopy is a noninvasive, portable, relatively inexpensive, and effective approach for assessment of the burn wound healing potential. It is more accurate if compared with clinical observation in burn depth assessment. It has a broader utility and is equally or more accurate compared with the more expensive videomicroscopy.
