Answer:
The Holliday-Segar Method is used to calculate the daily maintenance fluid requirements for children based on their weight. The formula is as follows:
1. For the first 10 kg of body weight: 100 mL/kg/day
2. For the next 10 kg of body weight: 50 mL/kg/day
3. For any weight above 20 kg: 20 mL/kg/day
Let's calculate the daily maintenance fluid volume for a child who weighs 12 kg:
1. For the first 10 kg: 10 kg × 100 mL/kg = 1000 mL
2. For the remaining 2 kg: 2 kg × 50 mL/kg = 100 mL
Total daily fluid requirement:
1000 mL + 100 mL = 1100 mL/day
To find the hourly infusion rate:
\[ \frac{1100 \text{ mL}}{24 \text{ hours}} = 45.83 \text{ mL/hour} \]
Therefore, for a child who weighs 12 kg:
- The daily maintenance fluid volume is **1100 mL**.
- The hourly infusion rate is approximately **45.83 mL/hour**.
