Renal failure: electrolytes

From My wiki

Jump to: navigation, search

Renal failure is often complicated by elevations in potassium, phosphate, and magnesium and decreases in sodium and calcium. Additionally, chronic renal failure patients often present with an anion gap metabolic acidosis. Urea, creatinine, uric acid, sulfate, phosphate, phosphorus, lipids, cholesterol, neutral fats, and some amino/organic acids may accumulate, while albumin levels fall

Renal Failure: Electrolytes

  • Elevated Electrolytes: potassium, phosphate, and magnesium
  • Decreased Electrolytes: sodium, calcium
  • Other Increases: urea, creatinine, uric acid, sulfate, phosphate, phosphorus, lipids, cholesterol, neutral fats, and some amino/organic acids
  • Other Decreases: albumin
  • Acid/Base: anion gap metabolic acidosis
