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.

Clavicular fractures are commonly encountered in the emergency department (ED). Fracture pain is usually treated with nonsteroidal anti-inflammatory drugs (NSAID) and opioids; however, both of these drug classes have potentially significant side effects that limit their use in certain patient populations. Hematoma blocks are safe and effective alternatives for pain control. ⋯ We present the case of a 39-year-old healthy man that presented to the ED with a clavicular fracture after a fall from a motorized scooter. He received minimal pain relief from hydrocodone-acetaminophen. A hematoma block was subsequently performed, with significant improvement in his pain. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Hematoma blocks are safe and effective treatments for clavicular fracture pain in the ED without the potentially significant side effects of NSAIDs and opioids.
