Using the Holliday-Segar method, what is the daily maintenance fluid requirement for a 12-kg child?

• A. 900 mL/day
• B. 1100 mL/day
• C. 1400 mL/day
• D. 1700 mL/day

Answer: (B)

Holliday-Segar maintenance fluids are based on weight in three tiers: 100 mL/kg per day for the first 10 kg, 50 mL/kg per day for the next 10 kg (11–20 kg), and 20 mL/kg per day for each kg over 20. For a 12-kg child, you calculate 100 mL/kg × 10 kg = 1000 mL for the first 10 kg, plus 50 mL/kg × 2 kg = 100 mL for the remaining 2 kg. Total maintenance runs to 1100 mL per day. So the daily maintenance fluid requirement is 1100 mL/day.
