1. What is the Glucose Infusion Rate Calculator?

The Glucose Infusion Rate (GIR) Calculator estimates the rate of glucose administration using the Starship Hospital formula. It helps healthcare providers monitor and adjust glucose infusion in clinical settings, particularly in neonatal and pediatric care.

2. How Does the Calculator Work?

The calculator uses the Starship Hospital formula:

Where:

• \( mL/kg/day \) — Milliliters per kilogram per day
• \( \% Dextrose \) — Percentage of dextrose solution
• \( 14.4 \) — Conversion factor

Explanation: The formula converts the volume and concentration of dextrose solution into glucose infusion rate in mg/kg/min.

3. Importance of GIR Calculation

Details: Accurate GIR calculation is essential for maintaining appropriate glucose levels in patients receiving intravenous glucose, preventing both hypoglycemia and hyperglycemia.

4. Using the Calculator

Tips: Enter mL/kg/day and % Dextrose values. Both values must be positive numbers to calculate the glucose infusion rate.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal GIR range?
A: Normal GIR varies by age and clinical condition, but typically ranges from 4-8 mg/kg/min in neonates and may be higher in specific clinical scenarios.

Q2: Why is the conversion factor 14.4?
A: The factor 14.4 converts mL/kg/day of dextrose solution to mg/kg/min, accounting for time and concentration units.

Q3: When should GIR be monitored?
A: GIR should be monitored in patients receiving intravenous glucose therapy, particularly in neonatal intensive care and pediatric settings.

Q4: Are there limitations to this calculation?
A: This calculation assumes constant infusion and may need adjustment for variable rate infusions or changing clinical conditions.

Q5: Can this calculator be used for adult patients?
A: While the formula is primarily used in pediatric care, it can be applied to adult patients with appropriate clinical judgment.
