Parkland Formula (Burn Resuscitation) — free guideline decision tool

Estimate 24-hour fluid resuscitation for major burns with the Parkland formula.

Total = 4 mL × weight(kg) × %TBSA (2nd/3rd degree); give half in the first 8 hours from the time of the burn. Multiply 4 mL × body weight (kg) × %TBSA (second-degree and deeper only); plan half of the 24-hour total in the first 8 hours counted from the time of injury.

Initial crystalloid resuscitation in significant burns.

Use the calculated volume as a starting crystalloid estimate, then titrate to urine output (~0.5 mL/kg/h in adults; higher targets in children or electrical injury per local burn protocol).

A starting estimate — titrate to urine output (~0.5 mL/kg/h adults). Time runs from the burn, not from arrival. Exclude superficial (first-degree) burns from %TBSA.

Exclude first-degree burns from %TBSA; overestimation drives fluid creep and oedema. Clock starts at the burn, not at ED arrival — subtract already-given fluid. Escalate early for inhalation injury, delayed presentation, or oliguria despite titration. For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
