Formula
Total 24 h = 4 mL × kg × %TBSA; ½ in first 8 h from injury, ½ over next 16 h.
Clinical pearls
- Count only partial- and full-thickness burns (not superficial/erythema); formal resuscitation is generally used for ≥20% TBSA in adults (≥10–15% in children).
- Time starts at the burn, not at ED arrival: subtract fluid already given and shorten the first-8-h window accordingly.
- The formula is a starting point; titrate hourly to urine output (0.5 mL/kg/h adults, 1 mL/kg/h children <30 kg). Current ABA guidance favours starting at 2 mL/kg/%TBSA in adults to avoid "fluid creep". Children also need maintenance fluid with dextrose.

FAQ
When does the 8-hour clock start in the Parkland formula?
From the time of the burn, not from hospital arrival.
Is the Parkland formula still used?
Yes as a starting estimate, but many burn centres now start at 2–4 mL/kg/%TBSA and titrate to urine output to avoid over-resuscitation.
