Four things you need to prescribe specifically in children, when prescribing fluids?

- Fluid type (concentration)
- Volume (e.g. 500mL bag)
- Rate (mL/hour)
- Additives if required

- Need daily U&Es

3

How do you calculate fluids based on weight, over 24 hours?

• For every kg up to 10kg 100mL/kg/day
• For every kg between 10‐20 kg 50mLkg/day
• For every kg over 20kg 20mL/kg/day

How do you calculate fluid deficit in dehydrated children?

%dehydration x weight x 10= total fluid deficit (mls)

This represents the extra fluid that is needed so should be added to total maintenance requirements.

The usual fluid for neonates?

10% dextrose

6

Two types of adverse drug reactions?

Type A: pharmacological mechanism of drug causing an effect e.g. badycardia caused by Beta-Blockers, predictable and related to dose.
