Which statement best describes optimal perioperative electrolyte management?

• A. Avoidance of severe hyponatremia or hyperkalemia; maintain euvolemia
• B. Aggressive correction of all electrolyte abnormalities
• C. Focus only on potassium management
• D. Routine saline for all patients

Answer: (A)

Optimal perioperative electrolyte management focuses on preventing dangerous electrolyte disturbances, particularly severe hyponatremia and hyperkalemia, while preserving euvolemia to ensure adequate organ perfusion and stable hemodynamics. Sodium and potassium imbalances have immediate implications for brain function and heart rhythm, and maintaining appropriate volume status helps with renal function and drug handling during surgery. This approach emphasizes monitoring and tailoring fluids and electrolytes rather than reflexively correcting every abnormal value; overzealous correction can cause harmful shifts and instability. Routine saline for all patients ignores individual needs and can contribute to fluid overload or electrolyte disturbances. So the best stance is to avoid severe hyponatremia or hyperkalemia and maintain euvolemia.
