Ever thought the Parkland Formula was a secret spell from Hogwarts? Plot twist! It’s actually a calculation used in the medical field to estimate the amount of fluid required for burn victims. (Mind blown, right?)

The Parkland Formula
Here’s the magical not-so-magical formula:
Fluid requirement = 4 ml x body weight (lbs) x % of total body surface area burned
Remember, this formula provides an estimate for the first 24 hours after a burn.
Categories of Parkland Formula Calculations
| Category | % of total body surface area burned | Fluid requirement (Imperial) |
|---|---|---|
| Minor | Less than 15% | Less than 2.03 oz |
| Moderate | 15-25% | 2.03 – 3.38 oz |
| Severe | More than 25% | More than 3.38 oz |
Examples of Parkland Formula Calculations
| Person | Body weight (lbs) | % of total body surface area burned | Fluid requirement |
|---|---|---|---|
| John Doe | 150 lbs | 20% | 4 ml x 150 lbs x 20% = 1200 oz |
| Jane Doe | 120 lbs | 15% | 4 ml x 120 lbs x 15% = 720 oz |
Evolution of Parkland Formula Over Time
| Year | Changes to the formula |
|---|---|
| 1960s | The birth of the formula |
| 1980s | Grew up to consider patient’s age and size |
| 2000s | Matured with modifications to improve accuracy |
Limitations of Parkland Formula
- Accuracy: This formula provides an estimate, not an exact measurement.
- Individual Factors: It doesn’t consider individual factors such as pre-existing health conditions.
Alternative Methods
| Method | Pros | Cons |
|---|---|---|
| Modified Brooke Formula | Better for kiddos | Not so great for grown-ups |
| Consensus Formula | Considers more individual factors | Needs a math whiz to calculate |
FAQs
- What is the Parkland Formula? The Parkland Formula is a calculation used to estimate the amount of fluid required for burn victims.
- How accurate is the Parkland Formula? The Parkland Formula provides an estimate, not an exact measurement.
- What are the categories of Parkland Formula calculations? They are minor, moderate, and severe, classified based on the % of total body surface area burned.
- What are some examples of Parkland Formula calculations? For example, for a person weighing 150 lbs with 20% of body surface area burned, the fluid requirement is 1200 oz.
- How has the Parkland Formula evolved over time? It was first developed in the 1960s, modified in the 1980s to consider patient’s age and size, and further refined in the 2000s for improved accuracy.
- What are the limitations of Parkland Formula? It provides an estimate, not an exact measurement and does not consider individual factors such as health conditions.
- What are some alternative methods to the Parkland Formula? The Modified Brooke Formula and Consensus Formula are some alternatives.
- What are the pros and cons of these alternative methods? The Modified Brooke Formula is more accurate for children but less so for adults. The Consensus Formula considers more individual factors but is more complex to calculate.
- Where can I learn more about the Parkland Formula? You can refer to reliable government and educational resources such as the CDC and NIH.
- How can I use the Parkland Formula Calculator? Simply input the body weight and the percentage of total body surface area burned to get an estimated fluid requirement.
