What is the 4-2-1 rule for pediatric fluids?

It's a shortcut for the Holliday-Segar method: 4 mL/kg for the first 10 kg, 2 mL/kg for the next 10 kg, and 1 mL/kg for every kg over 20 kg.

Pediatric Maintenance Fluids Calculator

Calculate daily fluid requirements for pediatric patients based on weight, essential for hydration management.

Proper hydration is vital for hospitalized children who cannot take fluids by mouth. Pediatric fluid requirements are not linear; they are based on the Holliday-Segar method, which estimates caloric expenditure and the resulting water needs. This calculator uses the '4-2-1 rule' to provide both the hourly infusion rate and the total 24-hour fluid volume required.

Nasıl Çalışır

The tool applies a tiered calculation based on the child's weight, ensuring that smaller infants receive proportionally more fluid per kilogram than older children or teenagers.

Hesaplama Formülü

Tiered: 4ml/kg (1st 10kg) + 2ml/kg (2nd 10kg) + 1ml/kg (rest)

Hesaplama Örnekleri

1. **25kg Child**: (10*4)+(10*2)+(5*1) = **65 mL/hr**.
