1. What is the Glucose Infusion Rate (GIR)?

The Glucose Infusion Rate (GIR) calculates the rate of glucose administration to neonates, expressed in mg/kg/min. It's crucial for managing neonatal hypoglycemia and ensuring appropriate glucose delivery.

2. How Does the Calculator Work?

The calculator uses the GIR equation:

Where:

• \( Infusion\ Rate \) — Intravenous fluid rate (mL/hr)
• \( Dextrose\ Concentration \) — Dextrose concentration (g/dL)
• \( Weight \) — Patient weight (kg)

Explanation: The equation converts the infusion parameters into mg of glucose per kg of body weight per minute.

3. Importance of GIR Calculation

Details: Accurate GIR calculation is essential for managing neonatal glucose homeostasis, preventing both hypoglycemia and hyperglycemia, particularly in preterm infants.

4. Using the Calculator

Tips: Enter the IV infusion rate in mL/hr, dextrose concentration in g/dL, and patient weight in kg. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical GIR range for neonates?
A: Term infants typically start at 4-6 mg/kg/min, while preterm infants may require 6-8 mg/kg/min initially.

Q2: How often should GIR be recalculated?
A: GIR should be recalculated whenever infusion rates or concentrations change, or if the infant's clinical status changes.

Q3: Does this account for other sources of glucose?
A: No, this calculates only the IV glucose infusion rate. Enteral feeds or other glucose sources must be considered separately.

Q4: What dextrose concentrations are typically used?
A: Common concentrations range from D5W (5 g/dL) to D25W (25 g/dL) depending on clinical needs.

Q5: How does weight affect GIR?
A: GIR is weight-normalized (mg/kg/min), so the same infusion parameters will deliver different GIRs to infants of different weights.
