PSA Flashcards
daily requirements of water
25-30ml / kg/ 24 hr
70kg person needs 1750ml-2100ml per day
daily requirement of Na
1mmol/kg/24h
70mmol per day
daily requirement of K
1mmol/kg/24h
70mmol per day
daily requirement of glucose per day
50-100g / 24h glucose
whats important to remember about replacing potassium ?
don’t replace it faster than 10mmol/h
how many mmol is NaCl 0.9% 1000ml?
150mmol
how many mmol is KCl 0.3% 1000ml?
40mmol
how many mmol is KCl 0.15% 1000ml?
20mmol
how many g is 5% glucose 1000ml?
50g
emergency resus fluids to prescribe ?
NaCl 0.9% solution, 500ml over 15 minutes
emergency hypoglycaemia what to prescibe in infusion?
glucose 20%, 100ml over 15mins
emergency hypercalcaemia fluids to prescribe ?
NaCl 0.9%, 1000ml, over 4h
emergency hypokalaemia fluid resus
NaCl 0.9% / KCl 0.3%, 1000ml, 4h
maintenance fluids without defifict or losses
25-30ml/kg/24h water
1mmol/kg/24h Na and K
50-100g/24h glucose
(aim 1000ml 9-12h)
maintenance fluids with deficits or losses e.g. Na/K
low, vomiting, diarrhoea
minimum 30ml/kg/24h water
ensure electrolytes replaced
note aim for 1000ml 4-6h
(quicker replacing time compared to if there were no defiicits)
