What this is
Compute initial fluid resuscitation for major thermal burns using the Parkland (4 mL/kg/%TBSA over 24 hours, half in the first 8 hours) and Modified Brooke (2 mL/kg/%TBSA) formulas. Sophie Well takes patient weight in kilograms, the estimated percent total body surface area burned (using the Rule of Nines for adults or the Lund-Browder chart for pediatrics), and the time of injury, then returns the initial drip rate and the 8-hour and 24-hour cumulative volumes for each formula.
When to use it
Use this when accepting a burn transfer or starting initial resuscitation in the field or ED on a patient with greater than 20% TBSA partial- or full-thickness burns. The formulas estimate starting fluid; ongoing titration follows urine output (0.5 mL/kg/hr in adults, 1 mL/kg/hr in pediatrics, higher in electrical injury) and hemodynamics, and over-resuscitation ("fluid creep") is a recognized harm. Both formulas count from the time of injury, not the time of arrival - if the patient is two hours post-burn on arrival, the first 8-hour window is already two hours in.
