An Evidence-Based Narrative Review of the Emergency Department Management of Acute Hyperkalemia.
The normal range for potassium is within narrow limits. Hyperkalemia is an electrolyte disorder that frequently affects patients in the emergency department (ED), and can result in significant morbidity and mortality if not identified and treated rapidly. ⋯ Hyperkalemia is a frequent electrolyte disorder in the ED. Because of the risk of fatal dysrhythmia due to cardiac membrane instability, hyperkalemia is a medical emergency. There is a lack of scientific evidence on the optimal management of hyperkalemia and more research is needed to establish optimal strategies to manage acute hyperkalemia in the emergency department.

Telemetry monitoring in patients with low-risk chest pain continues to be highly used despite a 2011 literature review and recommendations by the Clinical Practice Committee (CPC) of the American Academy of Emergency Medicine that did not find quality data to support its use. ⋯ No further quality data were identified to support the use of telemetry monitoring in patients with low-risk chest pains. Telemetry monitoring is unlikely to benefit patients with low-risk chest pain with a low-risk HEART Score.
