1. What is Fluid Deficit Calculation?

Fluid deficit calculation in pediatrics estimates the volume of fluid needed to correct dehydration in children. It is based on the child's weight and the estimated percentage of dehydration.

2. How Does the Calculator Work?

The calculator uses the fluid deficit formula:

\[ \text{Deficit (ml)} = \text{Weight (kg)} \times \text{Percentage deficit (\%)} \times 10 \]

Where:

Explanation: The formula calculates the total fluid deficit in milliliters based on the child's weight and the severity of dehydration.

3. Importance of Fluid Deficit Calculation

Details: Accurate fluid deficit calculation is crucial for proper rehydration therapy in dehydrated children, helping to prevent complications and ensure appropriate treatment.

4. Using the Calculator

Tips: Enter the child's weight in kilograms and the estimated percentage of dehydration. All values must be valid (weight > 0, percentage > 0).

5. Frequently Asked Questions (FAQ)

Q1: How is percentage of dehydration estimated?
A: Percentage of dehydration is typically estimated based on clinical signs such as skin turgor, mucous membranes, fontanelle, and overall appearance.

Q2: What are common percentages used for dehydration?
A: Mild dehydration: 3-5%, Moderate: 6-9%, Severe: ≥10% dehydration.

Q3: When should this calculation be used?
A: This calculation is used when planning rehydration therapy for dehydrated pediatric patients, either orally or intravenously.

Q4: Are there limitations to this calculation?
A: This is an estimation and should be used in conjunction with clinical assessment. Individual patient factors may require adjustment of fluid therapy.

Q5: How should the deficit be administered?
A: The calculated deficit is typically replaced over 24 hours, with half given in the first 8 hours and the remainder over the next 16 hours.
