Glucose Infusion Rate (GIR) Calculator

Description

Calculates the Glucose Infusion Rate (GIR) in mg/kg/min. This calculation is essential in neonatal and pediatric care to ensure adequate glucose delivery for metabolic needs while preventing hypoglycemia or hyperglycemia.

Usage

glucose_infusion_rate(iv_rate_ml_hr, dextrose_conc_percent, weight_kg)

Arguments

iv_rate_ml_hr	Numeric. The rate of intravenous fluid administration in mL per hour.
dextrose_conc_percent	Numeric. The concentration of dextrose in the fluid (e.g., 10 for D10W, 5 for D5W).
weight_kg	Numeric. The patient's weight in kilograms.

Value

A list containing:

GIR_mg_kg_min	The calculated glucose infusion rate.
Interpretation	General clinical context regarding standard maintenance ranges (typically 4-6 mg/kg/min for neonates).

Examples

# Example 1: Normal Maintenance
# 3 kg neonate, D10W running at 9 mL/hr
# GIR = (9 * 10) / (6 * 3) = 90 / 18 = 5.0 mg/kg/min
glucose_infusion_rate(9, 10, 3)

# Example 2: High Requirement
# 4 kg infant, D12.5W running at 15 mL/hr
# GIR = (15 * 12.5) / (6 * 4) = 187.5 / 24 = 7.81 mg/kg/min
glucose_infusion_rate(15, 12.5, 4)
