Parkland Baxter Formula:
| From: | To: |
The Parkland Baxter Formula is used to calculate fluid resuscitation requirements for burn patients during the first 24 hours after injury. It provides an estimate of the total fluid volume needed to maintain adequate circulation and prevent shock.
The calculator uses the Parkland Baxter formula:
Where:
Explanation: The formula calculates the total fluid requirement in milliliters for the first 24 hours after burn injury. Half of this amount is typically administered in the first 8 hours, with the remaining half given over the next 16 hours.
Details: Accurate fluid resuscitation is critical in burn management to prevent hypovolemic shock, maintain organ perfusion, and support recovery. Under-resuscitation can lead to renal failure, while over-resuscitation may cause pulmonary edema.
Tips: Enter patient weight in kilograms and burn area as a percentage of total body surface area. All values must be valid (weight > 0, burn area between 0-100%).
Q1: When should the Parkland Formula be used?
A: The formula is used for major burns (>20% TBSA in adults or >10% in children) during the first 24 hours after injury.
Q2: What type of fluid is typically used?
A: Lactated Ringer's solution is commonly used for initial resuscitation, as it most closely matches the electrolyte composition of plasma.
Q3: Are there adjustments for pediatric patients?
A: Yes, children may require additional maintenance fluids beyond the Parkland calculation due to their higher metabolic rates and body surface area to weight ratio.
Q4: What are the limitations of the Parkland Formula?
A: The formula provides an estimate only. Actual fluid needs should be guided by clinical response, urine output, and other hemodynamic parameters.
Q5: How is the fluid administered over time?
A: Typically, half of the calculated volume is given in the first 8 hours post-burn, and the remaining half is administered over the next 16 hours.
