Inputs
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
First 8 Hours
0.05cup
≈ 8 soda cans
How to Use This Calculator
- Enter patient weight (kg), total body surface area burned (%), and time since injury (hours).
- Review total Lactated Ringer's in 24 hours, first 8-hour volume, and next 16-hour volume.
- Adjust resuscitation based on urine output (target 0.5 mL/kg/hr in adults).
How the result changes with Patient Weight
| Patient Weight | Total Fluid (24 hr) | First 8 Hours |
|---|---|---|
| 31 | 2,480mL | 1,240mL |
| 106 | 8,480mL | 4,240mL |
| 195 | 15,600mL | 7,800mL |
| 270 | 21,600mL | 10,800mL |
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%.
