1. What is the Pediatric Fluid Rate Calculator?

Definition: This calculator estimates the hourly fluid requirements for pediatric patients using the Holliday-Segar formula.

Purpose: It helps healthcare professionals determine appropriate intravenous or oral fluid rates for children based on their weight.

2. How Does the Calculator Work?

The calculator uses the Holliday-Segar formula:

Where:

• \( W_{10} \) — Weight up to 10 kg
• \( W_{10-20} \) — Weight between 10-20 kg
• \( W_{20+} \) — Weight above 20 kg

Explanation: The formula calculates daily fluid requirements (ml/day) then converts to hourly rate (ml/hr):

• 100 ml/kg/day for first 10 kg
• 50 ml/kg/day for next 10 kg (11-20 kg)
• 20 ml/kg/day for remaining weight (>20 kg)

3. Importance of Accurate Fluid Calculation

Details: Proper fluid management is critical in pediatrics to prevent dehydration or fluid overload, especially in hospitalized patients.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the Holliday-Segar formula used for?
A: It estimates maintenance fluid requirements for pediatric patients based on weight.

Q2: When should I adjust the calculated rate?
A: Adjust for clinical conditions like fever, dehydration, renal or cardiac disease, as directed by a physician.

Q3: Does this include replacement fluids?
A: No, this calculates maintenance fluids only. Additional fluids may be needed for deficits or ongoing losses.

Q4: Can I use this for neonates?
A: No, different calculations are used for neonates (typically 60-80 ml/kg/day for term infants).

Q5: How precise should the rate be?
A: In clinical practice, rates are typically rounded to the nearest whole number for practicality.
