Maintenance fluid volume requirements based on body weight are as follows:


Weight (kg)

Volume per day

Volume per hour

0–10

100 ml/kg

4 ml/kg per hour

10–20

1000 ml + 50 ml/kg for each kg > 10

40 ml + 2 ml/(kg > 10)

20+

1500 ml + 20 ml/kg for each kg > 20

60 ml + 1 ml/(kg > 20)

More accurate estimations of the maintenance requirements can be made if the surface area is known; 1500 ml per square metre of surface area is required.

Note:

  • this method can be further simplified to provide maintenance ORT at home:
    • 1 oz per hour for infants
    • 2 oz per hour for toddlers
    • 3 oz per hour for older children (2) .
