What should be the hourly rate for Isabella's maintenance fluids?

To determine the correct hourly rate for Isabella's maintenance fluids, it is essential to apply the appropriate formula based on her weight and needs. In pediatric practice, the Holliday-Segar method is frequently utilized to calculate maintenance fluid requirements, which takes into account the patient's weight in kilograms.

For children, the formula is generally as follows:

• For the first 10 kg of body weight, administer 100 mL/kg/day.

• For the next 10 kg (from 11 to 20 kg), administer 50 mL/kg/day.

• For any weight above 20 kg, administer 20 mL/kg/day.

To arrive at the hourly rate, this total daily fluid requirement is then divided by 24 hours.

Assuming Isabella's weight falls within the range covered by this formula, if her total fluid requirement, calculated using the specific weight brackets defined (for instance, if she weighs around 15 kg), results in 1500 mL/day, this would convert to approximately 62.5 mL/hour. Thus, rounding down would give 62 mL/hour as a reasonable value, making this the accurate choice for her maintenance fluids.

This method provides an evidence-based approach to ensure children maintain adequate hydration tailored to their specific
