RESUMEN
Acute respiratory failure (ARF) is the leading cause of intensive care unit admission in patients with hematologic malignancies and is associated with a high mortality. The main causes of ARF are bacterial and opportunistic pulmonary infections and noninfectious lung disorders. Management consists of a systematic clinical evaluation aimed at identifying the most likely cause, which in turn determines the best first-line empirical treatments. The need for mechanical ventilation is a major determinant of prognosis. Beneficial outcomes have been demonstrated with early use of noninvasive ventilation (NIV) in selected patients with hematologic malignancies. However, most of these studies did not control the time between onset of ARF to NIV implementation nor accounted for the etiology of ARF or the presence of associated organ dysfunction at the time of NIV initiation. Moreover, the benefits demonstrated with NIV in these patients were derived from studies with high mortality rates of intubated patients. Additional studies are therefore warranted to determine the appropriate patients with hematologic malignancy and ARF who may benefit from prophylactic or curative NIV.
RESUMEN
Foreign body aspiration (FBA) is more common in children than adults with about 80% occurring in children aged less than 15 years. FBA in adults is often overlooked as a potential cause of airway obstruction especially if there is no asphyxiation. We present a case of a 45-year-old male with alcohol abuse who presented with post-obstructive pneumonia secondary to aspiration of tooth of unknown duration. The tooth was removed via flexible bronchoscopy (FBr) and we will discuss the use of FBr for foreign body (FB) removal, which FB can be easily removed by FBr, and the different techniques and devices used for FB removal via FBr.
