1. What is Pediatric Fluid Maintenance Calculation?

Definition: This calculator estimates the daily fluid requirements for children based on the Holliday-Segar method.

Purpose: It helps healthcare professionals determine appropriate intravenous or oral fluid administration for pediatric patients.

2. How Does the Calculator Work?

The calculator uses the Holliday-Segar formula:

Where:

• First 10 kg: 100 mL/kg/day
• Next 10 kg (11-20 kg): 50 mL/kg/day
• Above 20 kg: 20 mL/kg/day

Explanation: The formula accounts for decreasing metabolic demands per kg as body weight increases.

3. Importance of Pediatric Fluid Calculation

Details: Proper fluid calculation prevents dehydration while avoiding fluid overload, which is particularly important in children.

4. Using the Calculator

Tips: Enter the child's weight in kilograms. The calculator will automatically apply the appropriate formula based on weight ranges.

5. Frequently Asked Questions (FAQ)

Q1: Why does the formula change at different weights?
A: Metabolic rate per kg decreases as body size increases, so fluid needs per kg decrease accordingly.

Q2: Is this for IV or oral fluids?
A: The calculation applies to both, though clinical context may require adjustments.

Q3: When would I use a different calculation?
A: For neonates or special conditions (burns, renal failure, etc.), different formulas may be needed.

Q4: Does this include replacement fluids?
A: No, this is only for maintenance. Additional fluids may be needed for deficits or ongoing losses.

Q5: What about electrolytes?
A: This calculates water requirements. Electrolyte composition should be determined separately.
