1. What is the Parkland Formula?

The Parkland Formula is a medical guideline used to calculate the fluid replacement requirements for burn patients during the first 24 hours after injury. It's widely used in emergency and critical care settings.

2. How Does the Calculator Work?

The calculator uses the Parkland Formula:

\[ Fluid = TBSA \times Weight \times 4 \]

Where:

\( TBSA \) — Total Body Surface Area burned (percentage)
\( Weight \) — Patient's weight in kilograms
\( 4 \) — Constant multiplier (mL per %TBSA per kg)

Explanation: Half of the calculated fluid volume is administered in the first 8 hours post-burn, and the remaining half over the next 16 hours.

3. Importance of Fluid Calculation

Details: Proper fluid resuscitation is critical in burn management to prevent hypovolemic shock, maintain organ perfusion, and support recovery. The Parkland Formula provides a standardized approach to fluid replacement.

4. Using the Calculator

Tips: Enter TBSA as a percentage (0-100%) and weight in kilograms. Both values must be positive numbers. The result represents the total fluid requirement for the first 24 hours.

5. Frequently Asked Questions (FAQ)

Q1: When should the Parkland Formula be used?
A: The formula is used for major burns (typically >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 most commonly used, 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 and glucose-containing solutions to prevent hypoglycemia.

Q4: What are the limitations of the Parkland Formula?
A: It's a guideline, not an absolute rule. Individual patient factors (age, comorbidities, inhalation injury) may require adjustments. Clinical response should guide therapy.

Q5: How is the fluid administered?
A: Half of the calculated volume is given in the first 8 hours post-burn (from time of injury), with the remainder given over the next 16 hours.
