1. What is the Holliday-Segar Formula?

Definition: The Holliday-Segar method calculates daily maintenance fluid requirements for pediatric patients based on body weight.

Purpose: It helps healthcare providers determine appropriate intravenous or oral fluid administration for children.

2. How Does the Calculator Work?

The calculator uses the 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: This formula accounts for decreasing metabolic rates and fluid requirements per kg as children grow larger.

3. Importance of Pediatric Fluid Calculation

Details: Accurate fluid calculation prevents dehydration or fluid overload, both of which can be dangerous in pediatric 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: Why does the formula change at different weights?
A: Metabolic rate per kg decreases as children grow, so they require relatively less fluid per kg at higher weights.

Q2: Is this formula used for all children?
A: It's for healthy children. Adjustments may be needed for special conditions like renal failure or heart disease.

Q3: Does this include fluid for deficits or ongoing losses?
A: No, this is only for maintenance. Additional fluids may be needed for dehydration or abnormal losses.

Q4: What about neonates?
A: Different calculations are typically used for newborns (first 28 days of life).

Q5: How should the fluids be administered?
A: Typically given evenly over 24 hours, but clinical judgment is required based on the patient's condition.
