Planimetry study of the percent of body surface represented by the hand and palm: sizing irregular burns is more accurately done with the palm.
Sizing irregular burns is commonly done with use of the patient's hand as a template representing 1% of the body surface. To verify that this is accurate over a broad range of ages or to see if the surface of the palm is a more consistent template, a planimetry study was done. This revealed that the surface area of the palm averaged 0.52% total body surface area (+/- 0.07) and the palmar surface of the hand 0.85% total body surface area (+/- 0.08). The surface of the palm was a more consistent template and represented 0.5% of the body surface over a broad range of ages.

Clinical TrialBurn depth estimation by use of indocyanine green fluorescence: initial human trial.
Indocyanine green dye (ICG) fluoresces when illuminated by infrared light. After successful trials in a porcine model and with approval of the Massachusetts General Hospital's human studies committee, 10 adult patients with burn injuries were given 0.2 mg/kg ICG intravenously, and 825 nm fluorescence images were obtained with 780 nm excitation at 5 minutes after injection in the initial five patients and at 1, 2, 3, 4, 5, and 10 minutes in the subsequent five patients. Fluorescence intensities at burned and unburned sites were determined and images were correlated with burn depth as determined by healing or intraoperative assessment. ⋯ Imaging within 5 minutes of injection resulted in optimal contrast between injured and uninjured tissue. In this initial pilot trial it is apparent that ICG fluorescence has potential value as an aid in the early estimation of burn depth. In subsequent trials we will attempt to refine our ability to correlate ICG fluorescence images with burn depth.

Early assessment of pediatric burn wounds by laser Doppler flowmetry.
Evaluation of burn wound depth in pediatric patients is often difficult. A Laser Doppler Flowmeter with a temperature-controlled multichannel probe was used to measure burn wound perfusion as a tool to predict wound outcome. ⋯ Laser Doppler Flowmetry showed high positive predictive values for "nonhealing" wounds on postburn days 1, 2, and 3. These results suggest that Laser Doppler Flowmetry is a useful tool for burn wound assessment in pediatric patients.
