Parkland Formula for Burns Calculator

Calculate IV fluid resuscitation requirements for burn patients using the Parkland (Baxter) formula.

Inputs

lb

Parkland formula: 4 mL × kg × %TBSA Lactated Ringer's over 24 hours (½ in first 8 hr)

%

Fluid resuscitation indicated for TBSA >15–20% in adults; Rule of Nines for estimation

Results

Total Fluid (24 hr)

0.1cup

≈ 16 soda cans

Next 16 Hours0.05cup
Rate (First 8 hr)350mL/hr
Rate (Next 16 hr)175mL/hr
How to Use This Calculator
  1. Enter patient weight (kg), total body surface area burned (%), and time since injury (hours).
  2. Review total Lactated Ringer's in 24 hours, first 8-hour volume, and next 16-hour volume.
  3. Adjust resuscitation based on urine output (target 0.5 mL/kg/hr in adults).

What each input means

Patient Weight
Patient body weight in kilograms. Parkland (Baxter) formula: Total fluid = 4 mL × weight (kg) × %TBSA. Lactated Ringer's is the standard resuscitation fluid per ABA guidelines.
TBSA Burned
Percentage of total body surface area burned (second- and third-degree burns only). Use Rule of Nines: head 9%, each arm 9%, each leg 18%, trunk anterior 18%, trunk posterior 18%, perineum 1%.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Patient Weight = 70, TBSA Burned = 20 = 2 input(s) provided
  2. Calculate Total Fluid
    Total Fluid
    5600 = 5600
  3. Calculate First 8 Hours
    First 8 Hours
    2800 = 2800
  4. Calculate Next 16 Hours
    Next 16 Hours
    2800 = 2800
  5. Calculate Rate
    Rate
    350 = 350
