Calculation Formula

Fluid (mL) = 20 mL/kg + 20 mL for each 100 mL of previous intake

Where:
- 20 mL/kg: The base amount of fluid to give per kilogram of body weight
- 20 mL for each 100 mL of previous intake: Additional fluid based on the child's previous fluid intake

Understanding Cowlings Rule

Cowlings Rule is a simple formula used to estimate the amount of fluid a child needs when they are unable to take fluids by mouth. The formula is based on the child's weight and their previous fluid intake. It is important to note that this is an estimation and medical advice should be sought for precise fluid management.

Example Calculation

If a child weighs 10 kg and has previously consumed 200 mL of fluids, the calculation would be:

Fluid (mL) = 20 mL/kg + 20 mL for each 100 mL of previous intake

Fluid (mL) = (20 * 10) + (20 * (200 / 100))

Fluid (mL) = 200 + 40 = 240 mL
