Fluids

Method 1 — Maintenance fluid volume for a 24-hour period:

<ul >

<li>Weight less than 10 kg — 100 mL/kg</li>

<li>Weight >10 kg to 20 kg — 1000 mL for first 10 kg of body weight plus 50 mL/kg for any increment of weight over 10 kg</li>

<li>Weight >20 kg to 80 kg — 1500 mL for first 20 kg of body weight plus 20 mL/kg for any increment of weight over 20 kg, up to a maximum of 2400 mL daily</li>

</ul>

Method 2 — Maintenance fluid needed on an hourly basis:

<ul >

<li>Weight less than 10 kg — 4 mL/kg per hour</li>

<li>Weight >10 kg to 20 kg — 40 mL/hour for first 10 kg of body weight plus 2 mL/kg per hour for any increment of weight over 10 kg</li>

<li>Weight >20 kg to 80 kg — 60 mL/hour for first 20 kg of body weight plus 1 mL/kg per hour for any increment of weight over 20 kg, to a maximum of 100 mL/hour, up to a maximum of 2400 mL daily</li>

</ul>
