MANAGEMENT OF SEVERE HYPERKALEMIA

Life-threatening hyperkalemia in a patient with normal renal function

With media focus on benefits from reducing sodium intake, there is increased popularity of salt substitutes, typically potassium chloride. While viewed by the public as a healthy alternative to standard table salt, less appreciated is the severe risk with certain comorbidities and medications. We report the case of an elderly female with chronically high salt substitute intake, normal renal fun...

Arrhythmias and ECG changes in life threatening hyperkalemia in older patients treated by potassium sparing drugs.

BACKGROUND Severe hyperkalemia is a life threatening condition that can cause fatal rhythm disturbance and terminal heart arrest. The most common cause of hyperkalemia in older patients is that of iatrogenic medication-related etiology due to associated polymorbidity, polypharmacy and reduced reserve metabolic capacity. The aim of this paper is to increase awareness in the clinicians of the ris...

Life threatening hyperkalemia in a neonate with pseudo-hypoaldosteronism.

Pseudohypoaldosteronism type 1 is a rare disorder characterized by renal resistance to aldosterone which may present with a salt wasting crisis in infancy. We report a neonate with hyponatremia, severe dehydration and refractory life threatening hyperkalemia who was treated with dietary sodium chloride supplementation, potassium binding resins and fluid replacement therapy which proved to be li...
