Understanding Pediatric IV Fluid Calculations

In pediatric medicine, fluid administration is strictly calculated based on the child's body weight to prevent fluid overload or dehydration. The gold standard for determining maintenance fluid requirements is the Holliday-Segar Method, often referred to as the 4-2-1 rule for hourly calculations.

The Holliday-Segar Formula (Daily)

• First 10 kg: 100 ml per kg
• Next 10 kg (11-20 kg): 50 ml per kg
• Each kg above 20 kg: 20 ml per kg

How to Calculate IV Drip Rate

If an infusion pump is unavailable, clinicians must calculate the manual drip rate. The formula used is:

(Hourly Rate in ml/hr × Drop Factor in gtt/ml) ÷ 60 minutes = Drops per Minute (gtt/min)

Practical Example

For a child weighing 15 kg:

1. First 10 kg: 10 kg × 100 ml = 1,000 ml
2. Remaining 5 kg: 5 kg × 50 ml = 250 ml
3. Total Daily Maintenance: 1,250 ml / 24 hours
4. Hourly Rate: ~52 ml/hr
