Lund and Browder chart—modified versus original: a comparative study

Background: The Lund and Browder (LB) chart is currently the most accurate and widely used chart to calculate total body surface area affected by a burn injury. However, it is not easy to use charts to calculate burn percentages because of the difficulty in performing mathematical calculations with the percentages attributed to various body regions that are only partially burned. It is also cumbersome to have to perform mental calculations, especially in emergency situations. Methods: We compared results from the LB chart with a modified Lund and Browder (MLB) chart using 10 assessors on five different burn wounds each drawn on both charts. Results: Variability of results was significantly reduced using the MLB chart compared to the LB chart. Conclusions: Assessments performed using the MLB chart are less variable than those using the LB chart. Using this chart will help burn care providers rapidly, accurately, and reliably estimate burn extent.
