Sodium (Na

1 mmol/kg/24 hours |
Potassium (K
) |
0.5 mmol/kg/24hours |
Therefore maintenance for average 70 kg adult
- 3 litre H
O / 24 hr
- 80-100 mmol Na
/ 24hr
- 60 mmol K
/ 24hr
Common daily regimen for maintenance requirements (each litre is infused over
eight hours or at 125 ml/hour)
- 1L 5% Dextrose + 20 mmol KCl
- 1L NaCl 0.9% + 20 mmol KCl
- 1L 5% Dextrose + 20 mmol KCl
Alternative daily regimen for maintenance requirements (each litre is infused
over eight hours or at 125 ml/hour)
- 3L Solution 18 + 20 mmol KCl per litre
CAUTION with KCl
- Avoid concentration of 40 mmol/500 ml
- Avoid infusion rate of 15 mmol/hour
- Avoid potassium immediate post-op due to Cushing's response
