Successful airway management is critical to the practice of emergency medicine. Emergency physicians must be ready to optimize and prepare for airway management in critically ill patients with a wide range of physiologic challenges. Challenges in airway management commonly encountered in the emergency department are discussed using a pearl and pitfall discussion in this first part of a 2-part series. ⋯ This narrative review discusses the pearls and pitfalls of commonly encountered physiologic high-risk intubations with a focus on the emergency clinician.

Knowing the distinctive features of patients with the highest utilization of the emergency department (ED) is paramount to finding adequate alternatives to ED care for selected patients and improving health care quality and efficiency. ⋯ High-frequency users are an aged and heterogeneous group, requiring tailored interventions to improve care.

Stimulant poisoning frequently causes altered mental status (AMS) and can result in severe cerebral vascular complications. The role of noncontrast brain computed tomography (CT) in acute stimulant-poisoned patients presenting with AMS remains unclear. ⋯ Nontrauma stimulant-poisoned patients presenting with AMS and without focal neurologic symptoms were unlikely to have acute abnormalities on brain CT. Patients who underwent brain CT scans had worse consciousness and greater disease severity.

Primary carnitine deficiency (PCD) is a rare but potentially life-threatening genetic disorder if left untreated. Although some patients remain asymptomatic lifelong, a few patients present with hepatic encephalopathy, hypoglycemia, cardiomyopathy, dysrhythmia, and even sudden death. ⋯ A 25-year-old woman with PCD collapsed suddenly while eating lunch. Bystander cardiopulmonary resuscitation (CPR) was performed for 8 min, with automated external defibrillation once before admission. Upon arrival at our emergency department (ED), she was unresponsive without a pulse or spontaneous breathing. The initial heart rhythm on the electrocardiogram monitor was ventricular fibrillation (VF). The medical staff continued CPR with defibrillation for sustained VF. Return of spontaneous circulation (ROSC) was achieved after a total resuscitation time of 14 min, with defibrillation twice after cardiac arrest. The heart rhythm after ROSC was atrial fibrillation, with a rapid ventricular rate initially and subsequent progression to sinus tachycardia with diffuse ST segment depression and a prolonged QT interval. Her low carnitine level was consistent with her underlying disease. Cardiac magnetic resonance imaging and sonography for detection of cardiomyopathy showed no significant findings. With carnitine supplementation for a few days, her plasma carnitine level returned to 30 μM, with no recurrence of ventricular dysrhythmia. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: PCD is rare but could be life-threatening, and compiling detailed histories may help emergency physicians to determine the cause of sudden cardiac death after resuscitation. This information may be used to correct potential underlying problems and prevent recurrence of the condition after treatment.
