The Parkland Formula Calculator is designed to provide quick and accurate calculations of fluid requirements for burn patients. By simplifying this critical process, the calculator helps medical professionals make swift, informed decisions that are crucial in the early stages of burn treatment.
The Formula of Parkland Formula Calculator
The cornerstone of effective burn treatment is the precise calculation of fluid needs. The Parkland Formula is expressed as:
Here, each component holds significant value:
- 4 mL: This is the amount of fluid require per kilogram of body weight per percentage of total body surface area (%TBSA) burn.
- Body weight in kg: Patient’s weight is crucial as it directly influences the volume of fluids needed.
- %TBSA burned: Represents the percentage of the body affected by burns, critical for calculating the necessary fluid volume.
Understanding and applying each of these elements accurately ensures effective treatment.
Table of Normal Values Using the Parkland Formula for Different Age Groups
| Age Group | Average Weight (kg) | %TBSA Burned | Fluid Volume for First 24 hrs (mL) |
|---|---|---|---|
| Infants (0-1 yr) | 10 | 20 | 800 |
| Children (2-12 yrs) | 20 | 20 | 1600 |
| Teenagers (13-19 yrs) | 50 | 20 | 4000 |
| Adults (20-50 yrs) | 70 | 20 | 5600 |
| Older Adults (>50 yrs) | 70 | 20 | 5600 |
Explanation:
- Infants (0-1 yr): Infants typically have lower body weights, and the fluid volume is calculate on a smaller scale.
- Children (2-12 yrs): Children vary in size, but a median weight is use here for general estimation.
- Teenagers (13-19 yrs): Teenagers, as they approach adult size, have fluid requirements closer to those of smaller adults.
- Adults (20-50 yrs): This group represents the general adult population with an average adult weight.
- Older Adults (>50 yrs): Older adults may have the same calculation as younger adults, but clinical adjustments might be necessary based on health status.
Example of Parkland Formula Calculator
Consider a scenario where a patient weighing 70 kg has sustained burns covering 25% of their body. Using the Parkland Formula:
Fluid volume = 4 mL × 70 kg × 25% = 7000 mL
This calculation shows the fluid requirement for the first 24 hours post-burn.
Most Common FAQs
%TBSA can be estimate using tools like the ‘Rule of Nines’ which divides the body into sections that represent 9% or multiples of the total body surface area.
Calculations should start as soon as possible, ideally within the first hour post-injury, to ensure timely fluid administration.
Adjustments may be necessary based on specific patient needs and clinical judgment. It’s crucial to consult specialized pediatric or geriatric guidelines in these cases.
