Remember that this fluid management formula is only a guideline.   Furthermore, this fluid regimen does not include normal maintenance fluids.   Fluid management must be individualized.  Additional parameters for fluid management include urine output & systemic blood pressure. 

The 24 hour formula is
fluids for 24 hours = (4 х kg х  %burn) [2^nd & 3^rd added together]
with 1^st 50% of that total in the first 8 hours and the 2^nd 50% over the following 16 hours.
