Definition
Hyperkalemia is best defined as a serum potassium concentration greater than 5.5 mEq/L in adults; levels higher than 7 mEq/L can lead to significant hemodynamic compromise
Causes
Life-Threatening Causes
Immediate life-threatening causes are conditions which result in immediate death or disability if left untreated.
- Acute Renal Failure
- Rhabdomyolysis
- Rapid tissue necrosis
- Tumor Lysis syndrome
- Metabolic acidosis, diabetic ketoacidosis
- Massive hemolysis
- large IV doses of Calcium chloride or calcium gluconate
- Adrenal insufficiency
Common Causes
- Pseudoyperkalemia
- Renal insufficiency
- Adrenal insufficiency
- Medications; ACE inhibitors, Angiotensin receptor blockers, amiloride,spironolactone, NSAIDS, ciclosporin, Tacrolimus, Trimethoprim, Pentamidine
- Renal tubular acidosis
- Iatrogenic
Management
Please find below an algorithm that summarizes the approach to hyperkalemia

Do's and Don'ts
- Place the patient on a closely monitored bed
- Repeat basic metabolic panels frequently
- may want to avoid Kayexalate in patients who are already having diarrhea
- Remove the offending medications that are associated with Hyperkalemia
- Keep the patient well hydrated
- Check levels of other electrolytes as it may be abnormal as well.
- Avoid over treating with IV Bicarbonate as it may lead to rebound metabolic alkalosis
- Consider consultation with nephrology
