1. What is the NICU Fluid Calculator?

Definition: This calculator estimates the total daily fluid requirements for neonates in the NICU based on their weight and standard fluid ranges.

Purpose: It helps healthcare professionals determine appropriate fluid volumes for neonatal care, ensuring proper hydration while avoiding fluid overload.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Fluid = 100-150 \times Weight \]

Where:

\( Fluid \) — Total daily fluid requirement (ml/day)
\( Weight \) — Neonatal weight (kg)
\( 100-150 \) — Standard fluid range (ml/kg/day)

Explanation: The neonatal weight is multiplied by the selected fluid range (typically 100-150 ml/kg/day) to calculate total daily fluid requirements.

3. Importance of Fluid Calculation in NICU

Details: Accurate fluid calculation is critical in neonates to maintain electrolyte balance, support organ function, and prevent complications like dehydration or fluid overload.

4. Using the Calculator

Tips: Enter the neonate's weight in kilograms and select the appropriate fluid range (100 ml/kg/day for restricted fluids or 150 ml/kg/day for standard maintenance). Weight must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the fluid range 100-150 ml/kg/day?
A: This range accounts for maintenance needs while allowing adjustment based on clinical status (e.g., 100 ml/kg/day for fluid restriction, 150 ml/kg/day for standard needs).

Q2: When would I use 100 vs 150 ml/kg/day?
A: Use 100 ml/kg/day for neonates requiring fluid restriction (e.g., ELBW infants, PDA, renal impairment). Use 150 ml/kg/day for stable neonates with normal fluid requirements.

Q3: Does this include all fluid sources?
A: Yes, this calculation represents total daily fluids including IV, enteral feeds, and medications.

Q4: How often should fluid requirements be recalculated?
A: Daily, as neonatal weight and clinical status can change rapidly in the NICU.

Q5: What adjustments might be needed?
A: Consider clinical factors like insensible water losses, phototherapy, renal function, and specific conditions (e.g., NEC, PDA) that may require fluid modification.
