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. The average perfusion levels for wounds that healed spontaneously in fewer than 21 days was significantly higher than the average perfusion levels for wounds that required excision and grafting or were not healed by day 21 after burn injury. 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.
