# Burn Fluid Resuscitation (Parkland/Brooke) Calculate the 24-hour crystalloid for moderate-to-severe burns using Parkland (4 mL/kg/%TBSA LR) or Brooke (2 mL/kg/%TBSA LR), accounting for elapsed time since burn. Titrate to urine output. Derived from Baxter 1974, ABA 2008, MDCalc, and ISBI 2016.

It splits the volume between the first 8 hours and the following 16 hours. This calculator is not medical advice. ## Inputs - **Formula** (select) - **Weight (kg)** (number): Patient body weight (kg). - **TBSA Burned (%)** (number): Total Body Surface Area burned (%), 2nd and 3rd degree only. Use Rule of Nines (adult), Lund-Browder (children), or palm method. - **Hours Since Burn** (number): Hours elapsed since the TIME OF BURN (not admission). Used to compute the remaining first-8-h volume. - **Decimal Places** (number) ## When to use - Estimate initial crystalloid volume for burns using the Parkland or Brooke formula. - Calculate how much of the first-8-hour volume remains after time has elapsed since the burn. - Compare Parkland and Brooke estimates for a documented weight and TBSA percentage. ## How it works - Enter the patient’s weight in kilograms, the percentage of second- and third-degree TBSA burned, and hours since the burn occurred. - Choose Parkland at 4 mL/kg/%TBSA or Brooke at 2 mL/kg/%TBSA. - The calculator estimates the total lactated Ringer’s volume for 24 hours, with half assigned to the first 8 hours and half to the next 16 hours. - It accounts for elapsed time and returns the remaining first-8-hour volume, hourly rates, and selected formula in JSON format. ## Use cases - Emergency and burn-unit teams can estimate initial 24-hour crystalloid requirements from weight, TBSA, and burn time. - Medical students can compare the volume and hourly rates produced by the Parkland and Brooke formulas. - Clinicians can recalculate the remaining first-8-hour volume when a patient presents after the burn occurred. ## Frequently asked questions ### Which burns should be included in the TBSA percentage? Include second- and third-degree burns. Do not include first-degree burns. ### Does the timer start at admission? No. Enter the hours since the burn occurred, not the hours since hospital admission. ### What is the difference between Parkland and Brooke? Parkland uses 4 mL/kg/%TBSA, while Brooke uses 2 mL/kg/%TBSA. ### What fluid does the calculator use? The estimates are for lactated Ringer’s crystalloid solution. ### Can this calculator replace clinical judgment? No. Fluid administration must be assessed and titrated by qualified clinicians, including monitoring urine output.

Unit selectable: cells/µL or ×10⁹/L (1 ×10⁹/L = 1000 cells/µL). Adult reference ≥ 1500 cells/µL. Neutropenia risk strata: mild 1000–1500, moderate 500–1000, severe < 500 (agranulocytosis < 200) — high risk of serious infection, and febrile neutropenia is a medical emergency. Clinical uses: chemotherapy cycles typically require ANC ≥ 1500 to proceed and ≥ 500 for discharge from protective isolation; carbimazole/clozapine monitoring; congenital neutropenia workup. Neutrophilia > 7500 suggests bacterial infection, inflammation, steroids, or a myeloproliferative neoplasm. If only segmented % is reported, set band % to 0; if the instrument reports an absolute neutrophil count directly (NE#), this tool is not needed. Based on ASCO/IDSA neutropenia guidance, Boxer ASH 2012, and MDCalc.

Standard formula AG = Na⁺ − Cl⁻ − HCO₃⁻ (mmol/L), or AG = Na⁺ + K⁺ − Cl⁻ − HCO₃⁻ with optional potassium. A high AG (≈ >12, or >20 with K⁺) indicates accumulation of unmeasured anions (lactic acidosis, ketoacidosis, renal failure, and toxins such as methanol/ethylene glycol, salicylates — mnemonic GOLD-MARK). A normal AG (8–12) during metabolic acidosis points to a hyperchloremic (normal-anion-gap) acidosis: diarrhea, renal tubular acidosis, saline resuscitation. A low AG (<3–6) is usually hypoalbuminemia, also hypercalcemia/hypermagnesemia, lithium, cationic IgG paraproteins, or bromide pseudo-hyperchloraemia. Optional albumin correction AG_corrected = AG + 2.5 × (4.0 − albumin g/dL) avoids missing a high-AG acidosis in hypoalbuminemia. Derived from Kraut CJASN 2007, Figge 1998, and MDCalc.

Conventional formula (calcium mg/dL, albumin g/dL): Ca_corr = Ca + 0.8 × (4.0 − Albumin). SI formula (calcium mmol/L, albumin g/L): Ca_corr = Ca + 0.02 × (40 − Albumin). Roughly 40% of circulating calcium is albumin-bound, so low albumin lowers the measured total without changing the physiologically active ionized fraction. Corrected reference range ≈ 8.5–10.5 mg/dL (2.15–2.60 mmol/L). Low → true hypocalcemia (hypoparathyroidism, vitamin-D deficiency, CKD, hypomagnesemia, citrated transfusion, pancreatitis, sepsis); high → true hypercalcemia (primary hyperparathyroidism, malignancy/PTHrP, myeloma, vitamin-D intoxication, thiazides, immobilization, granulomatous disease). When albumin is markedly abnormal or acid-base is deranged, ionized calcium remains the gold standard. Based on Payne BMJ 1973 and MDCalc.

Bazett (1920): QTc = QT/√RR (classic; over-corrects at high HR, under-corrects at low HR). Fridericia (1920): QTc = QT/RR^(1/3) — more accurate across a wide HR range, preferred for drug/QT studies. Framingham (1992): QTc = QT + 0.154×(1 − RR) — simple linear regression. RR is derived from heart rate (RR = 60/HR) when not provided; QT and QTc in ms. Thresholds: men > 450 ms borderline / > 480 ms prolonged; women > 460 ms borderline / > 480 ms prolonged; > 500 ms markedly prolonged. Derived from Bazett 1920, Fridericia 1920, Sagie/Framingham 1992, AHA 2009, ICH E14, and MDCalc.

Classic Katz (1973) formula Na_corr = Na + 1.6 × (Glucose − 100)/100 (glucose mg/dL), or Hillier (1999) Na_corr = Na + 2.4 × (Glucose − 100)/100 which is more accurate at very high glucose (Katz tends to underestimate). Glucose unit selectable: mg/dL or mmol/L (reference 5.5 mmol/L). Hyperglycemia shifts water extracellularly and dilutes sodium; the corrected value reflects the real water balance. Corrected Na < 135 indicates true hyponatremia (DKA/HHS with free-water excess, SIADH, GI/renal losses); > 145 indicates true hypernatremia (common in HHS, signals free-water deficit and guides replacement). Derived from Katz NEJM 1973, Hillier 1999, Adrogué NEJM 2000, and MDCalc.

Choose the weight basis: Actual Body Weight (ABW), Ideal Body Weight (IBW, Devine 1974), or Adjusted Body Weight (AdjBW = IBW + 0.4 × (ABW − IBW), for obese patients). Optional SCr floor at 1.0 mg/dL for elderly / low-muscle-mass patients. Returns an UN-indexed CrCl in mL/min — the value drug-dosing tables use (for BSA-indexed eGFR use MDRD or CKD-EPI). Derived from Cockcroft & Gault, Nephron 1976. Valid for stable renal function in adults. Not medical advice. - [eGFR Calculator (MDRD Simplified)](https://elysiatools.com/en/tools/egfr-mdrd): Estimate glomerular filtration rate (eGFR) with the simplified 4-variable MDRD equation (2006 re-expressed, IDMS-traceable): eGFR (mL/min/1.73 m²) = 175 × SCr^−1.154 × Age^−0.203 × (0.742 if female) × (1.212 if Black). The 175 constant replaced the original 186 after IDMS-standardized creatinine calibration. The legacy race coefficient 1.212 is OFF by default (the 2021 CKD-EPI race-free equation removed it) and is provided only for historical comparison. Returns a BSA-INDEXED eGFR for CKD staging (G1–G5); for drug dosing use un-indexed CrCl (Cockcroft-Gault). Derived from Levey AS et al., Ann Intern Med 2006. Valid for stable adults, not AKI/pregnancy/extremes.
