Parkland Formula Burn Fluid Calculator
x402
Parkland Formula Burn Fluid Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-12).
Calculates Parkland formula crystalloid resuscitation volume for adult burn patients (4 mL × kg × %TBSA for 24 hours, with half given in the first 8 hours from time of injury), per Baxter 1974.

How this service works
Adult Parkland crystalloid volume: 4 mL × kg × %TBSA for 24 hours, half in the first 8 hours from the time of injury. Baxter 1974. Deterministic published arithmetic with citation; not a treatment order, IV prescription, or urine-output titration.
Output
Returns the computed total 24-hour crystalloid volume in mL, the first 8-hour aliquot, and the second 16-hour aliquot, based on the deterministic Parkland formula (4 mL × weight in kg × %TBSA), with citation to Baxter 1974. Result is a reference calculation only, not a treatment order.
Example use cases
ED burn resuscitation fluid calculation
“I have a 75 kg patient who came in with 28% total body surface area burns. Run the Parkland formula and tell me the total fluid volume for 24 hours and how much to give in the first 8 hours.”
Prehospital transport fluid planning
“We're transporting a burn victim who weighs 165 pounds with approximately 40% TBSA burns. What does the Parkland formula say about fluid requirements for the first 8 hours versus the full 24?”
Medical education burn scenario
“For a 60 kg patient with 20% TBSA burns, calculate the Parkland formula fluid volumes so I can walk through the Baxter 1974 resuscitation math with my students.”

Endpoint
GEThttps://api.magentlab.com/api/calc/parklandWhen to prefer
Use this endpoint when you need a fast, deterministic, citable Parkland formula calculation for adult burn resuscitation volume. Prefer it over manual arithmetic when accuracy and citation traceability (Baxter 1974) matter. Accepts weight in either kilograms or pounds, making it flexible for clinical workflows. Not intended for pediatric-specific formulas (e.g., Galveston) or real-time titration guidance.
Side effects
- Missing required tbsa_percent parameter returns validation error
- tbsa_percent of 0 is explicitly invalid and rejected
- Negative or out-of-range weight values may return error or unexpected results
- Neither weight_kg nor weight_lb provided results in missing input error
- Non-numeric query parameter values cause schema validation failure
