1. What is the Maintenance Fluid Calculator?

The Maintenance Fluid Calculator for Pediatrics uses the Holliday-Segar formula to estimate daily fluid requirements for children based on body weight. This calculation is essential for proper hydration management in pediatric patients.

2. How Does the Calculator Work?

The calculator uses the Holliday-Segar formula:

\[ Fluid\ (mL/day) = 1000 \times first\ 10kg + 50 \times next\ 10kg + 20 \times over\ 20kg \]

Where:

First 10 kg: 100 mL/kg/day
Next 10 kg (11-20 kg): 50 mL/kg/day
Over 20 kg (>20 kg): 20 mL/kg/day

Explanation: The formula accounts for decreasing fluid requirements per kilogram as body weight increases, reflecting the body's changing metabolic needs.

3. Importance of Maintenance Fluid Calculation

Details: Accurate maintenance fluid calculation is crucial for preventing dehydration or fluid overload in pediatric patients, especially during illness, surgery, or when oral intake is inadequate.

4. Using the Calculator

Tips: Enter the child's weight in kilograms. The weight must be a positive value. The calculator will automatically apply the appropriate formula based on the weight category.

5. Frequently Asked Questions (FAQ)

Q1: What is the Holliday-Segar formula used for?
A: It's used to calculate daily maintenance fluid requirements for children based on body weight, commonly applied in hospital settings for intravenous fluid therapy.

Q2: Are there any adjustments needed for specific conditions?
A: Yes, fluid requirements may need adjustment for fever, dehydration, renal failure, cardiac conditions, or other special circumstances under medical supervision.

Q3: How accurate is this calculation?
A: The Holliday-Segar formula provides a good estimate for most healthy children but should be individualized based on clinical assessment and specific patient needs.

Q4: Can this be used for neonates?
A: Different formulas are typically used for neonates, as their fluid requirements differ significantly from older infants and children.

Q5: How should the calculated fluid be administered?
A: Maintenance fluids are typically administered evenly over 24 hours, but the rate and composition should be determined by healthcare providers based on individual patient needs.
