1. What is a Neonatal Glucose Infusion Rate Calculator?

Definition: This calculator determines the glucose infusion rate (GIR) for neonates based on the glucose concentration, infusion rate, and patient weight.

Purpose: It helps healthcare professionals maintain appropriate glucose levels in newborns, especially preterm infants or those with glucose regulation issues.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( GIR \) — Glucose infusion rate (mg/kg/min)
• \( C \) — Glucose concentration (mg/mL)
• \( R \) — Infusion rate (mL/h)
• \( W \) — Patient weight (kg)

Explanation: The formula converts the total glucose delivery rate into a weight-normalized value per minute.

3. Importance of GIR Calculation

Details: Proper GIR calculation is critical for preventing hypoglycemia or hyperglycemia in neonates, which can both have serious consequences.

4. Using the Calculator

Tips: Enter the glucose concentration (typically 5-15%), infusion rate in mL/h, and the neonate's weight in kg. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal GIR range for neonates?
A: Typically 4-8 mg/kg/min for most neonates, but may vary based on gestational age and clinical condition.

Q2: How do I convert percentage to mg/mL?
A: Multiply percentage by 10 (e.g., 10% glucose = 100 mg/mL).

Q3: Why is the denominator 6 in the formula?
A: The factor of 6 converts hours to minutes (60 min/h) and accounts for the mg to kg relationship.

Q4: When would I need to adjust GIR?
A: Based on blood glucose monitoring results, clinical condition, and the neonate's metabolic needs.

Q5: Does this calculator account for other IV fluids?
A: No, this calculates GIR only. Total fluid requirements should be calculated separately.
