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.

Educational use only. This tool does not replace clinical judgment or local protocols.

使い方

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.

計算式

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

Calculation Examples

1. **5kg Infant**: 5 * 4 = **20 mL/hr**. 2. **25kg Child**: (10*4) + (10*2) + (5*1) = **65 mL/hr**.

Why use this tool in your daily life?

This service ensures hydration safety for the most vulnerable patients. By automating the tiered calculation, it eliminates the risk of dehydration or fluid overload in pediatric care, making it an indispensable tool for pediatric nurses and residents.
