Parkland Formula Calculator

The Parkland Formula is a clinical guideline used to estimate the volume of IV fluid required by a burn patient in the first 24 hours after injury. The formula is: Total Fluid (mL) = 4 × Weight (kg) × TBSA Burned (%). It uses Ringer's Lactate as the preferred solution due to its physiologic properties.

Only 2nd degree (partial thickness) and 3rd degree (full thickness) burns are included when calculating TBSA for the Parkland Formula. Superficial 1st degree burns, such as mild sunburn, are excluded because they do not cause significant fluid loss.

50% of the calculated total fluid is given in the first 8 hours post-burn, and the remaining 50% is administered over the following 16 hours. Note that the 8-hour clock starts from the time of the burn injury, not from when treatment begins.

Ringer's Lactate (also called Lactated Ringer's) is the IV solution of choice for burn resuscitation because its electrolyte composition closely resembles plasma, making it more physiologically appropriate than normal saline. It helps minimize the risk of hyperchloremic acidosis that can occur with large volumes of normal saline.

No. The Parkland Formula estimates only the additional fluid required to replace losses from the burn injury itself. It does not account for routine daily maintenance fluid requirements, which must be calculated and added separately for the patient's overall fluid management plan.

It is purely an estimate and a starting point for fluid resuscitation. Continuous monitoring of vital signs, urine output (targeting 0.5–1 mL/kg/hr in adults), and hemodynamic status is required. The calculated volumes should be titrated based on the patient's clinical response.

Fluid resuscitation is generally indicated for burns covering greater than 20% TBSA in adults and greater than 15% TBSA in children or elderly patients. Smaller burns may be managed with oral hydration, but any significant burn should be assessed by a clinician.

The standard Parkland Formula is designed for adults. For pediatric patients, the modified Parkland or Galveston Formula is typically used, which also incorporates maintenance fluid requirements. Always consult burn care guidelines or a specialist when treating pediatric burn patients.
