Give about 8,400 mL of lactated Ringer’s over 24 hours, half in the first 8 hours.

  • Run the first 8 hours at roughly 525 mL/hr, then 263 mL/hr for the next 16 hours.
  • The 24-hour window begins at the time of the burn, so subtract any time already elapsed when setting the initial rate.
  • Titrate to a urine output of 35-70 mL/hr (the formula is only a starting estimate).

Next stepPlace a urinary catheter and reassess the rate hourly against urine output and vital signs.
