Asthma is a chronic inflammatory illness with acute exacerbations, which often is encountered in the ED setting. Knowledge of the presentation and treatment of asthma is crucial for any physician treating patients with this disease. Beta-agonist, anticholinergic, and corticosteroid therapy continue to be the mainstay of emergency therapy despite advances in newer medications. Proper attention to long-term treatment of asthma and aggressive treatment of acute exacerbations should help reduce morbidity and mortality.

ReviewAcute exacerbations of chronic obstructive pulmonary disease.
This article discusses the definition, pathophysiology, cause, clinical presentation, laboratory work-up, and treatment of chronic obstructive pulmonary disease (COPD) exacerbation. The focus is on the presentation of acute exacerbations of COPD in the emergency department and the available evidence for testing and treatment.

ReviewCommunity-acquired pneumonia in the emergency department: a practical approach to diagnosis and management.
Pneumonia is one of the most common conditions for which patients seek emergency care. It is a challenging infection in that the spectrum of illness ranges from the nontoxic patient appropriate for outpatient antibiotics to the critically ill patient requiring intensive care hospitalization. Current data and diagnostic technology provide the emergency physician with the tools for an appropriately rapid evaluation and consideration of the differential diagnosis. ⋯ Although antibiotic-resistant organisms increasingly are being identified, patients continue to benefit from early institution of standard ED treatment. Coverage for atypical organisms improves patient response and outcome. Finally, identification and treatment of the complications of pneumonia and accompanying sepsis must be considered by the ED physician when evaluating critically ill patients.

ReviewManagement of the difficult airway: alternative airway techniques and adjuncts.
Rapid-sequence intubation using conventional laryngoscopic technique remains the standard of airway management in emergency medicine and continues to have a success rate of approximately 98%. Preparation and proper intubation technique must be optimized at the initial attempt using direct laryngoscopy. Failure causes multiple repeated attempts, leading to a failed airway. ⋯ Without proper technique, even with proper positioning, the glottic opening cannot be visualized. Laryngeal pressure to maneuver the larynx into position should be exerted initially by the laryngoscopist's right hand and, when in view, maintained by an assistant to free the laryngoscopist's hand for ETT insertion. With preparation and proper technique, the first attempt is the best attempt, and the vicious cycle of multiple attempts and complications will be averted.
