Randomized Controlled Trial
Chair-sitting exercise intervention does not improve respiratory muscle function in mechanically ventilated intensive care unit patients.
Chair-sitting may allow for more readily activated scalene, sternocleidomastoid, and parasternal intercostal muscles, and may raise and enlarge the upper thoracic cage, thereby allowing the thoracic cage to be more easily compressed. ⋯ Six days of chair-sitting exercise training did not significantly improve respiratory muscle function in mechanically ventilated patients.

The data available to guide clinical management of acute lung injury and acute respiratory distress syndrome are much more limited for infants and children than for adult patients. This paper reviews the available medical data and the pertinent physiology on the management of pediatric patients with acute lung injury. With the collaboration of multicenter investigation networks, definitive pediatric data may be on the horizon to better guide our clinical practice.

A simple method for effective bronchodilator aerosol delivery while administering continuing continuous positive airway pressure (CPAP) would be useful in patients with severe bronchial obstruction. ⋯ CPAP bronchodilator delivery decreases the work of breathing as effectively as does standard nebulization, but produces a greater oxygenation improvement in patients with airway obstruction. To optimize airway humidification, a heat-and-moisture exchanger could be used with the Boussignac CPAP system, without modifying aerosol delivery.

Rhodococcus equi is an emerging opportunistic pathogen in immunocompromised patients. A lung-transplant recipient developed weight loss, nonproductive cough, dyspnea, and somnolence. ⋯ Our patient developed R. equi infection soon after a course of high-dose corticosteroids for acute allograft infection and animal exposure. A course of intravenous vancomycin followed by single-agent long-term therapy with oral ciprofloxacin was successful.
