Using the Holliday-Segar method, what is the maintenance fluid requirement for an 18 kg child per day?

• A. 1400 mL/day
• B. 1200 mL/day
• C. 1800 mL/day
• D. 1000 mL/day

Answer: (A)

Maintenance fluids for children follow the Holliday-Segar method: 100 mL/kg/day for the first 10 kg, then 50 mL/kg/day for the next 10 kg (and 20 mL/kg/day for weight above 20 kg). For an 18 kg child, that’s 10 kg × 100 = 1,000 mL plus 8 kg × 50 = 400 mL, totaling 1,400 mL per day. So the maintenance fluid requirement is 1,400 mL/day.
