Kaliumchlorid + Glucose B. Braun (Potassium Chloride, Glucose)

Kaliumchlorid + Glucose is an intravenous electrolyte solution used in conditions that require potassium repletion and an energy substrate.

• Hypokalemia: restores low serum potassium levels and prevents cardiac complications.
• Potassium supplementation: provides controlled potassium delivery during surgery or critical care.
• Energy provision during IV therapy: glucose supplies calories to patients unable to eat orally.

• The potassium chloride component dissociates to release potassium ions that are taken up by cells, helping to re‑establish normal membrane potential and cardiac electrophysiology. The glucose portion is metabolized via glycolysis, delivering immediate energy and supporting cellular function during periods of fasting or stress associated with intravenous treatment.

Adverse reactions may occur with any intravenous electrolyte preparation. Monitoring and prompt management are essential.

Common Side Effects

• Pain or irritation at the injection site.
• Mild hyperkalemia causing transient ECG changes.
• Phlebitis or inflammation of the vein.
• Transient hyperglycemia.
• Electrolyte imbalance such as sodium shift.

Serious or Rare Side Effects

• Severe hyperkalemia leading to life‑threatening arrhythmias.
• Cardiac arrest due to electrolyte disturbance.
• Anaphylactic or severe hypersensitivity reaction.
• Metabolic acidosis from rapid infusion.
• Pulmonary edema secondary to fluid overload.

Careful patient assessment and monitoring reduce the risk of complications.

• Serum potassium monitoring: check levels before and during infusion.
• Blood glucose monitoring: especially in diabetic patients.
• Renal impairment: adjust dose or infusion rate.
• Avoid rapid infusion: infuse over the recommended time to prevent cardiac events.
• Contraindicated in existing hyperkalemia.
• Store at 2‑8°C: keep refrigerated, protect from light, do not freeze or shake.

Potassium chloride and glucose can interact with several drug classes, requiring vigilance.

Major Interactions (Avoid)

• ACE inhibitors or ARBs: may potentiate hyperkalemia.
• Potassium‑sparing diuretics (e.g., spironolactone): increase risk of excess potassium.
• Trimethoprim‑containing antibiotics: can raise serum potassium.

Moderate Interactions (Monitor Closely)

• Insulin: may cause rapid intracellular shift of potassium.
• Beta‑blockers: can mask signs of hypoglycemia and affect potassium balance.
• Digoxin: elevated potassium can enhance digoxin toxicity.
