Using the Holliday-Segar method, what is the maintenance fluid requirement for a 60 kg child per day?

• A. 1800 mL/day
• B. 2100 mL/day
• C. 2600 mL/day
• D. 2400 mL/day

Answer: (B)

Holliday-Segar uses weight-based tiers to estimate daily maintenance fluids: 100 mL/kg for the first 10 kg, 50 mL/kg for the next 10 kg, and 20 mL/kg for every kilogram over 20 kg. For a 60 kg child, calculate: 10 kg × 100 = 1000 mL, plus 10 kg × 50 = 500 mL, plus 40 kg × 20 = 800 mL. Sum = 2300 mL per day. While rounding or using the 4-2-1 rule can yield around 2400 mL/day in practice, the Holliday-Segar method gives 2300 mL/day for a 60 kg child.
