The amount of fluid per kg varies based on weight ranges, as described by the Holliday-Segar method for estimating daily fluid requirements. Here's a breakdown:
Holliday-Segar Method for Fluid Requirements
The Holliday-Segar nomogram provides a way to approximate daily fluid needs, considering different weight ranges. It outlines the amount of fluid needed per kilogram of body weight:
- First 10 kg: 100 ml/kg
- Second 10 kg: 50 ml/kg
- Remaining weight: 20 ml/kg
Practical Examples
To illustrate, here are a few examples demonstrating how to calculate the total daily fluid requirements:
-
Example 1: 8 kg Child
- The child weighs 8 kg, which falls within the first 10 kg.
- Fluid requirement: 8 kg * 100 ml/kg = 800 ml
-
Example 2: 15 kg Child
- First 10 kg: 10 kg * 100 ml/kg = 1000 ml
- Remaining 5 kg: 5 kg * 50 ml/kg = 250 ml
- Total fluid requirement: 1000 ml + 250 ml = 1250 ml
-
Example 3: 25 kg Child
- First 10 kg: 10 kg * 100 ml/kg = 1000 ml
- Second 10 kg: 10 kg * 50 ml/kg = 500 ml
- Remaining 5 kg: 5 kg * 20 ml/kg = 100 ml
- Total fluid requirement: 1000 ml + 500 ml + 100 ml = 1600 ml
Summary Table
| Weight Range | Fluid Requirement |
|---|---|
| First 10 kg | 100 ml/kg |
| Next 10 kg | 50 ml/kg |
| Remaining kg | 20 ml/kg |
