1. What is Pediatric Fluid Calculation?

The pediatric fluid calculator determines appropriate daily fluid intake for children based on weight, using the Holliday-Segar method for maintenance fluids with optional adjustments for specific clinical conditions.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where Maintenance is calculated by:

• 100 ml/kg/day for first 10 kg
• 50 ml/kg/day for next 10 kg (11-20 kg)
• 20 ml/kg/day for each kg above 20 kg

Explanation: This method accounts for decreasing metabolic demands per kg as children grow larger.

3. Importance of Fluid Calculation

Details: Accurate fluid calculation is essential for maintaining hydration, electrolyte balance, and preventing both dehydration and fluid overload in pediatric patients.

4. Using the Calculator

Tips: Enter weight in kg, age in years, and any clinical adjustments needed. Adjustments can be positive (additional fluids needed) or negative (fluid restriction required).

5. Frequently Asked Questions (FAQ)

Q1: When should I use adjusted fluids?
A: Use adjustments for conditions like fever (+12% per °C above 38°C), diarrhea, burns, or fluid restriction in renal/cardiac conditions.

Q2: What about neonates?
A: This calculator is for children >1 month. Neonates have different requirements (60-100 ml/kg/day initially).

Q3: How often should fluids be recalculated?
A: Recalculate daily with weight changes, or more frequently with rapid clinical changes.

Q4: Are there exceptions?
A: Yes, critically ill children or those with SIADH, diabetes insipidus, or major electrolyte imbalances need individualized plans.

Q5: What's the maximum safe fluid intake?
A: Generally don't exceed 2400 ml/m²/day without careful monitoring to avoid fluid overload.
