Check if the regular maintenance IV fluid has potassium chloride in the solution.

Maintenance IV fluid containing potassium may be adequate.
Parenteral maintenance dose can be provided in maintenance IV fluids as:

Not greater than 4 mmol/100 mL (20 to 40 mmol/L) of potassium chloride in peripheral IV fluids;

Not greater than 8 mmol/100 mL (80 mmol/L) of potassium chloride in central IV fluids
The daily parenteral maintenance dose of potassium:

Weight	Dose
<1500 g	2 to 5 mmol/kg/day
≥1500 g	1.5 to 3.0 mmol/kg/day

Severe (Serum potassium <1.5 mmol/L) or symptomatic hypokalaemia with ECG changes (2)

Discuss with clinician in-charge prior to rapid IV correction of hypokalaemia. Dose and administration may be altered as the clinical condition dictates.

0.3 to 0.5 mmol/kg potassium chloride diluted with 2 mL/kg of sodium chloride 0.9% over 2 to 3 hours. Do not exceed rate of 0.2 mmol/kg/hour

Repeat dose if serum potassium level is not corrected.
