1mmol/kg/24h Na and K
50-100g/24h Glucose
(Aim 1000ml 8-12h)
Maintenance fluids with deficits or losses
eg Na or K low, Vomiting, diarrhoea
Minimum 30ml/kg/24h water
ensure electrolytes replaced

Childrens Emergency resuscitation
Nacl 0.9% 10ml/kg 15mins
Childrens maintenance no deficits/losses
<10Kg = 100ml/kg/24h
10-20kg = 50ml/kg/24h
>20kg = 20ml/kg/24h
usually Nacl 0.9%/Glucose 5%
When should IV fluid therapy be reviewed
- After each bolus in shocked pts
- every 12 hrs if req > 3litres a day
- daily in Stable pts
When to use 250ml bolus in 15 mins for resuscitation
