Parkland Formula

This is a starting estimate, not a prescription. Titrate to urine output — 0.5 mL/kg/hr in adults, 1 mL/kg/hr in children — and to clinical perfusion, adjusting the rate up or down as required. Over-resuscitation carries real harm (compartment syndrome, pulmonary oedema, “fluid creep”), so the figures above should not be infused unchanged regardless of response. The clock runs from the time of the burn. Formal resuscitation is generally reserved for burns ≥15–20% TBSA in adults and ≥10% in children. Some centres now start at 2 mL/kg/%TBSA for non-electrical adult burns and titrate upward; follow local protocol. Electrical burns and inhalational injury commonly require more.
