Guidelines for the Use of Potassium Chloride

Recommended Neonatal Dose, Route, and Interval

Initial oral replacement Therapy:

  • 5-1 mEq/kg/day in divided doses
  • Small, more frequent aliquots preferred (every feed or every other feed)
  • Adjust dosage based on monitoring of potassium concentrations
  • 1mEq K = 74.6 mg KCl

Acute treatment of symptomatic Hypokalemia

  • Begin with 0.5 to 1 mEq/kg IV to infuse at 0.3-0.5mEq/kg/hr (Max rate = 1mEq/kg/hr)
  • Maximum concentration: 40 mEq/L for peripheral & 80 mEq/L for central venous infusions.

Chief Indications

  • Treatment of Hypokalemia
  • Adjunct to diuretic therapy
  • Prevention of digoxin toxicity potentiated by hypokalemia

Possible Adverse Reactions:

  1. Hyperkalemia
  2. PO administration may cause GI irritation, vomiting, diarrhea, bleeding.
  3. IV administration may cause irritation, pain or phlebitis at the infusion site.
  4. Rapid IV infusion may cause cardiac arrhythmias.

Contraindications & Precautions

  • Hypersensitivity to potassium chloride products
  • Severe renal impairment or hyperkalemia
  • Use with caution in patients with cardiac disease

Nursing Implications

  • Monitor serum potassium concentrations. If serum potassium level is not rising with effective potassium supplementation, consider checking a magnesium level.
  • Continuous cardiac monitoring is mandatory for IV replacement especially for central infusions
  • Peripheral Line Concentration = 0.1mEq/mL; Central Line Concentration = 0.2mEq/mL
  • Watch IV site for signs of irritation or phlebitis.
  • KCl oral supplementation will be diluted by pharmacy to a concentration of 1mEq/mL
  • Give oral doses with the nearest feed.
