Daytime fatigue and sleep disturbance are frequent complaints in patients with amyotrophic lateral sclerosis (ALS). However, polysomnographic data are sparse. Nocturnal respiratory insufficiency may occur despite nearly normal daytime pulmonary function. We describe the clinical presentation and polysomnographic findings in two patients with clinically and electrophysiologically confirmed ALS with minimal ...

We studied the effect of abrupt discontinuation of inhaled nitric oxide (iNO) in patients receiving this drug for treatment of acute hypoxemic respiratory failure (AHRF), in order to determine the need for continued therapy, the incidence and nature of adverse events, and the risk factors predicting these adverse events. Thirty-one ...

Chemical control of breathing in obstructive sleep apnoea (OSA) patients has been studied by many authors. The results of previous studies, especially those dealing with hypoxic drive, are discordant. Respiratory responses were studied during hypercapnic and hypoxic stimulation in a group of 37 normocapnic patients with OSA during wakefulness. The ...

Non invasive ventilation refers to the technique of providing ventilatory support without a direct conduit to the airway. It is a promising new technique, which is particularly useful in patients with COPD. Patients with COPD are prone to develop acute exacerbations, which pushes them into acute respiratory failure. Under these ...

INTRODUCTION: Prone ventilation improves oxygenation in selected patients with acute respiratory distress syndrome (ARDS). However, prone positioning of critically ill patients with multiple invasive lines and tubes is potentially dangerous. Trauma patients, in particular, may require special consideration because of skeletal fixation devices or prior operative procedures. Our objective was ...

Miliary coccidioidomycosis indicates hematogenous or lymphatic spread of Coccidioides immitis and is characterized by the development of multiple small granulomas throughout the lungs and other organs. Previous reports have suggested that this disorder occurs almost exclusively in immunocompromised patients, with most patients succumbing to progressive respiratory failure. In this article, ...

Routine turning of critically ill patients is a standard of care. In recent years, specialized beds that provide automated turning have been introduced. These beds have been reported to improve lung function, reduce hospital-acquired pneumonia, and facilitate secretion removal. This trial was designed to measure the physiological effects of routine ...

Noninvasive ventilation refers to any form of ventilatory support applied without the use of an endotracheal tube. It offers the potential to provide primary treatment for acute respiratory failure while avoiding complications associated with mechanical ventilation with endotracheal intubation. Noninvasive ventilation has been most commonly studied in hypercapnic respiratory failure. ...

The heat shock/stress proteins (HSP), and, in particular, the inducible, cytosolic Hsp70, represent an extremely conserved response to many different cellular injuries, including reactive oxygen species (ROS). Hsp70 has been shown to confer to cells and tissues protection against the deleterious effects of ROS or cytokines, both in vitro and ...

NPPV is useful in decreasing the intubation rate in carefully selected patients with acute respiratory failure--particularly in patients with COPD. The results of some studies also suggest a survival benefit for use of NPPV with acute respiratory failure associated with COPD. Heliox therapy may be beneficial for selected patients with ...

Laparoscopy can be performed while patients are under total intravenous anesthesia (TIVA), or sedated and breathing spontaneously through the normal airway. Respiratory monitoring is difficult when patients are sedated or anesthetized, however. The purposes of this study were to evaluate the reliability of end-tidal carbon dioxide (ETCO2) measurement for monitoring ...

In this project we evaluate the dynamic changes during expiration at different levels of positive-end-expiratory pressure (PEEP) in ventilated patients. We wanted to discriminate between normal lung function and acute respiratory distress syndrome (ARDS). After approval by the local Ethic Committee we studied two ventilated patients: (one with normal lung ...

OBJECTIVE: Intensivists generally view patients with hematological malignancies as poor candidates for intensive care. Nevertheless, hematologists have recently developed more aggressive treatment protocols capable of achieving prolonged complete remissions in many of these patients. This change mandates a reappraisal of indications for ICU admission in each type of hematological disease. ...

Actin-scavenging proteins, e.g., plasma gelsolin, counteract the pathophysiological consequences of actin leaked into the circulation from dying cells, but the capacity of this defense system can be overwhelmed by massive tissue injury. We examined the prognostic implications of plasma gelsolin levels obtained near the time of admission to our level ...

We describe a patient who developed tetany with sudden respiratory arrest after the infusion of intravenous diltiazem. The administration of calcium chloride rapidly resolved the patient's tetany with prompt recovery of respiratory function, averting the need for more aggressive airway management and ventilatory support. The emergency physician should be aware ...
