1. What is the IT Ratio?

The IT (Insulin to Total) ratio is a calculation used in neonatal care to adjust insulin therapy based on the infant's weight. It helps determine the appropriate insulin dosage for newborns.

2. How Does the Calculator Work?

The calculator uses the IT ratio formula:

Where:

• \( IT_{decimal} \) — Insulin to total ratio in decimal form
• \( Weight_{kg} \) — Newborn weight in kilograms

Explanation: The equation adjusts the insulin dosage proportionally to the newborn's weight to ensure appropriate therapy.

3. Importance of IT Ratio Calculation

Details: Accurate IT ratio calculation is crucial for managing neonatal diabetes or hyperglycemia, preventing both hypoglycemia and hyperglycemia complications.

4. Using the Calculator

Tips: Enter the IT ratio in decimal form (e.g., 0.05 for 1:20 ratio) and the newborn's weight in kilograms. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical IT ratio for newborns?
A: Common starting ratios range from 0.02 to 0.1 (1:50 to 1:10), but this should be determined by a healthcare provider.

Q2: How often should the IT ratio be recalculated?
A: The ratio should be reassessed whenever the newborn's weight changes significantly or if glycemic control is inadequate.

Q3: When is IT ratio adjustment needed?
A: Adjustment is needed for very low birth weight infants or when standard insulin protocols don't achieve glycemic targets.

Q4: Are there limitations to this calculation?
A: This is a starting point - clinical judgment and frequent glucose monitoring are essential for safe insulin therapy.

Q5: Should this be used for preterm infants?
A: Extreme caution is needed for preterm infants who may have greater insulin sensitivity - consult a neonatologist.
