Glucose Infusion Rate

Calculate the total glucose infusion rate from up to three concentrations of dextrose.

Input Weight  kg lb
D5 Rate   mL/hr
D10 Rate   mL/hr
D Rate   mL/hr
 
 
Total GIR = 
 mg/kg/min

 

This calculation is a simple conversion of units (into mg/kg/min):

GIR =  IV Rate (mL/hr) * Dextrose Conc (g/dL) * 1000 (mg/g)
Weight (kg) * 60 (min/hr) * 100 (mL/dL)

where the dextrose concentration is expressed as a whole number, e.g. 5 or 10.

A GIR of 5-8 mg/kg/min is typical. Infants who are not feeding should not be allowed a rate less than 5 mg/kg/min for any significant period of time. The GIR needed to optimize nutrition in neonates is 14 mg/kg/min.
