Surfactant-replacement therapy is a life-saving treatment for preterm infants with respiratory distress syndrome, a disorder characterized by surfactant deficiency. Repletion with exogenous surfactant decreases mortality and thoracic air leaks and is a standard practice in the developed world. ⋯ Two of these disorders, meconium aspiration syndrome and bronchopulmonary dysplasia, might also be amenable to surfactant-replacement therapy. This paper discusses the use of surfactant-replacement therapy beyond respiratory distress syndrome and examines the evidence to date.

Comprehensive management of chronic obstructive pulmonary disease (COPD) includes proper assessment, monitoring of disease, reduction of risk factors, the management of stable COPD, and the prevention and management of exacerbations. The 2007 COPD guidelines from the Global Initiative for Chronic Obstructive Lung Disease address each of these aspects of COPD management in detail and provide evidence-based recommendations for patients and health-care professionals. Reduction of risk factors emphasizes the importance of smoking cessation and control of environmental indoor and outdoor pollutants. ⋯ Since exacerbations influence lung function and clinical decline in patients with COPD and contribute to the cost of caring for this disease, efforts must be directed at prevention and management of exacerbations. In addition to controlled oxygen therapy, antimicrobials, brief courses of systemic corticosteroids and, on occasion, noninvasive or invasive mechanical ventilation may play a role. The role of respiratory therapists in the prevention, diagnosis, and management of stable COPD and exacerbations is absolutely essential if the goals of the 2007 Global Initiative for Chronic Obstructive Lung Disease guidelines are to be attained.

Ventriculopleural shunts are uncommonly used for the treatment of normal pressure hydrocephalus in adults. Pleural effusion has been reported to complicate the course of these ventriculopleural shunts in children. The pleural effusion should typically resemble the cerebrospinal fluid unless frankly infected. ⋯ We discuss the possible mechanisms in the development of the effusion. It is important to be aware of this unlikely complication of an uncommon procedure. Recognizing the origin of the pleural effusion can help in instituting close follow-up and early referral for revision of the ventriculopleural shunt.

Spirometric testing is one of the oldest clinical tests still in use today. It is a straightforward test that has the patient maximally exhale from total lung capacity. The key measurements are the forced expiratory volume in the first second (FEV(1)) and the maximum exhaled volume (vital capacity [VC]). ⋯ Using this measurement can diagnose the presence and severity of airway obstruction. This can be used to guide therapies and predict outcomes. Using spirometry to screen for obstructive lung disease, however, can be problematic, and the effect of screening on outcomes has yet to be demonstrated.

Although existing evidence confirms that no pharmacologic agent ameliorates the decline in the lung function or changes the prognosis of chronic obstructive pulmonary disease (COPD), inhaled pharmacotherapy is a critical component of the management for patients suffering with COPD. Inhaled agents are directed to provide immediate relief of symptoms and to restore functional capacity in treatment of stable COPD. ⋯ Respiratory therapists play an important role in the implementation of these guidelines, since they are often responsible for educating patients on the correct use of the inhalers. This paper reviews current evidence regarding the use of inhaled pharmacotherapy in the treatment of COPD and provides a guided approach to the use of different agents in stable COPD.
