Russell et al reported equations for estimated total blood volume in pediatric patients based on body weight.
Parameters:
(1) body weight in kilograms
total blood volume in mL =
= (85.27 * (body weight in kilograms)) - 25 mL
|
Body Weight
|
Total Blood Volume in mL =
|
|
3 to 10 kg
|
(58.2 * (body weight)) + 142
|
|
10 to 12 kg
|
(82.7 * (body weight)) + 17
|
|
20 to 30 kg
|
(95.7 * (body weight)) - 274
|
where:
• Lean body weight should probably be used instead of actual body weight.
• Gender is not distinguished.
