parkland_burn_formula: Parkland Formula for Burn Resuscitation

Description

Calculates the fluid resuscitation requirements for burn patients within the first 24 hours of injury using the Parkland Formula. It determines the total volume of Lactated Ringer's solution required, split into the first 8 hours (50%) and the subsequent 16 hours (50%).

Usage

parkland_burn_formula(weight_kg, tbsa_percent)

Value

A list containing:

Total_Fluid_24h_mL

Total estimated fluid requirement for the first 24 hours.

First_8h_Volume_mL

Volume to be administered in the first 8 hours.

First_8h_Rate_mL_hr

Infusion rate for the first 8 hours.

Next_16h_Volume_mL

Volume to be administered in the next 16 hours.

Next_16h_Rate_mL_hr

Infusion rate for the next 16 hours.

Arguments

weight_kg

Numeric. Patient weight in kilograms.

tbsa_percent

Numeric. Total Body Surface Area burned as a percentage (e.g., enter 20 for 20%).

Details

The formula used is: $$Total\_Fluid (mL) = 4 \times Weight (kg) \times TBSA (\%)$$ Half of this total is administered in the first 8 hours from the time of injury, and the remaining half is administered over the next 16 hours.

Examples

# Example 1: 75kg adult with 20% TBSA burn
# Total = 4 * 75 * 20 = 6000 mL
# First 8h = 3000 mL (375 mL/hr)

# Example 2: 50kg patient with 40% TBSA burn
# Total = 4 * 50 * 40 = 8000 mL
