The electrical defibrillator has been proven to be a life-saving device in the treatment of cardiac arrest due to ventricular tachycardia or ventricular fibrillation. An understanding of the physiology and technology behind this device is useful for providers of emergency care. ⋯ The physiology and the technical considerations will make up the bulk of the discussion. The latest developments in electrical defibrillation also will be reviewed.

A 51-yr-old woman was transferred to the emergency department with nonspecific interscapular pain and a progressive right-sided hemiparesis. Physical examination and laboratory examination revealed moderate right-sided hemiparesis, with no other focal neurologic deficits. A computed axial tomography scan of the brain was negative. ⋯ Subsequently, the patient developed a left-sided sensory deficit, and magnetic resonance imaging of the cervical spine revealed a C5-T2 epidural hemorrhage. The patient underwent emergent surgical evacuation of the clot and recovered without incident. Spinal epidural hematomas are rare and typically present as cord compressions with or without pain rather than as unilateral hemiplegia.

Previous studies have suggested that most emergency department (ED) patients who leave without being seen by a physician (LWBS) are nonurgent. Our institution developed a fast-track process to reduce length of stay (LOS) for these patients. The present study was conducted to determine the effect of reducing LOS on the number of ED patients who leave without seeing a physician and the acuity of this subset of ED patients. ⋯ Of these, 35 were nonurgent and 16 were urgent. There was a significant decrease in the LWBS proportion after the CQI process was implemented. We conclude that (1) reducing LOS is associated with a decrease in the number of ED patients who leave without seeing a physician and (2) many patients who leave without being seen are classified as urgent at presentation.

Review Case Reports
Mediastinal teratoma presenting as massive hemoptysis in an adult.
Massive hemoptysis is a rare but potentially life-threatening presentation in the emergency department (ED). We describe a case of massive hemoptysis caused by a mediastinal teratoma in an otherwise healthy young man. ⋯ A differential diagnosis for massive hemoptysis is presented. The initial management of these patients in the ED and the diagnostic options are discussed.
