STEP 1. Determine the total body surface area (TBSA) that is burned.
STEP 2. Calculate the casualty's weight in kilograms. (Divide pounds
STEP 3. Calculate and replace fluids using this formula:
Fluid = Ringer's X TBSA
* is the fluid to replace in the first 24 hours after the burn.
Use the TBSA number without the percent when working the formula. For
example, the TBSA is 45 percent; multiply by 45. The TBSA is 70 percent;
multiply by 70.
STEP 4. Replace the amount of fluid determined in Step 3 as follows:
(a) During the first 8 hours give one-half of the total calculated fluids.
(b) During the second 8 hours, give one-fourth of the total calculated
During the third 8 hours, give one-fourth of the total calculated
