Pediatric calculations are ok until I got stuck on my last question regarding fluid maintenance. Can someone explain it? I have the following problem.
The child weighs 17kg. would need how many ml/day of fluids for maintenance? and how many ml/hr?
I thought it was 1000 ml/24hrs plus 50/kg/day????? I am so stuck it's making my head spin.
Please help. Thanks...

[QUOTE=ADPIE10;2943975]We were given the following formula for 100% maintenance in 24 hour fluid requirements in Pediatrics:
[INDENT]1st 10 Kg of body weight, give 100 ml/Kg
2nd 10 Kg of body weight, give 50 ml/Kg
Above 20 Kg of body weight, give 20 ml/Kg
Just being curious, as I don't do pediatrics, I do neonates, But..trying to work out your formula out of interest.
If you had for example, a kid who weighed 30 kgs, would you give
150ml/kg, ....Plus another 20ml/kg?
If it weighed 40 kgs, would it be the same???
Or if the kid was 30kgs would it just be 20ml/kg, which doesn't sound a lot of fluid replacement?
In our NICU, we go 60 mls/kg: 90 mls/kg; 120mls/kg; and take it from there. Sometimes we start on 75 mls/kg..eg hypoglycaemia, or can go from 60-75 if conservative management of say cardiac babies.
Usually end up at 180mls /kg on long term preemies who are not yet demand feeding.

Hi Adpie10, I dont quite know, i was a bit flummoxed by the formula.
Just interested in how to work out that paeds formula, as opposed to neonates, where it seems so simple!
if it were the case that you had a 40kg kid, then yes, would you give 150mls/kg for the first 20kg...(ok, easy!)
but would you then add 20mls/kg over the weight or would you go with just 20mls/kg which seems such a little
