What are the 4 types of fluids you need to know for the PSA?
- NaCl 0.9% 1000ml – 150mmol Na
- KCl 0.3% 1000ml – 40mmol K
- KCl 0.15% 1000ml – 20mmol K
- glucose 5% 1000ml – 50g glucose
How many mmol of Na are in NaCl 0.9% 1000ml?
150 mmol
How many mmol of K are in KCl 0.3% 1000ml?
40 mmol
How many grams of glucose are in glucose 5% 1000ml?
50 grams
How many mmol of KCl are in KCl 0.15% 1000ml?
20 mmol
What are the daily electrolyte requirements for maintenance fluids?
- 25-30ml/kg/24h water
- 1mmol/kg/24h Na and K
- 50-100g/24h glucose
What is the maximum rate of K per hour?
Max rate of 10mmol/h
How much and how long should maintenance only fluid be given over?
1000ml in 8-12 hours
How much and how long should maintenance and deficits (e.g. Na or K low, vomiting, diarrhoea) fluid be given over?
1000ml in 4-6 hours
What fluid is used for emergency resuscitation?
sodium chloride 0.9% 500ml over 10 mins
What fluid is used for emergency hypoglycaemia?
glucose 20% 100ml over 15 mins
What fluid is used for emergency hypokalaemia?
sodium chloride 0.9% / potassium chloride 0.3% 1000ml over 4 hours
What fluid is given for emergency hypercalcaemia?
sodium chloride 0.9% 1000ml over 4 hours
What fluid is given for emergency resuscitation in children?
NaCl 0.9% 10ml/kg over 10 minutes
How is maintenance fluid calculated in children and what is the fluid of choice?
100ml/kg/24h for <10kg
50ml/kg/24h for 10-20kg
20ml/kg/24hr for >20kg
100-50-2- rule
NaCl 0.9% / glucose 5%
