CONTEXT Although electrophysiologic and histologic neuromuscular abnormalities are common in intensive care unit (ICU) patients, the clinical incidence of ICU-acquired neuromuscular disorders in patients recovering from severe illness remains unknown. OBJECTIVES To assess the clinical incidence, risk factors, and outcomes of ICU-acquired paresis (ICUAP)(More)
RATIONALE AND OBJECTIVES The respective influence on the incidence of ventilator-associated pneumonia of currently available systems used for warming and humidifying the gases delivered to mechanically ventilated patients, that is, heated humidifiers and heat and moisture exchanger filters, remains controversial. METHODS We addressed this question in a(More)
OBJECTIVE Pulse oximetry (SpO2) is a standard monitoring device in intensive care units (ICUs), currently used to guide therapeutic interventions. Few studies have evaluated the accuracy of SpO2 in critically ill patients. Our objective was to compare pulse oximetry with arterial oxygen saturation (SaO2) in such patients, and to examine the effect of(More)
UNLABELLED Patients with pseudocholinesterase (BChE) variants may exhibit markedly prolonged paralysis after the administration of succinylcholine or mivacurium. We sought to evaluate to what extent molecular biology may contribute to the biological assessment of such patients. We conducted a prospective cohort study in patients referred to our center(More)
OBJECTIVES To assess whether the presence and severity of intensive care unit-acquired paresis are associated with intensive care unit and in-hospital mortality. DESIGN Prospective, observational study. SETTING Two medical, one surgical, and one medico-surgical intensive care units in two university hospitals and one university-affiliated hospital. (More)
OBJECTIVE Although critical illness neuromyopathy might interfere with weaning from mechanical ventilation, its respiratory component has not been investigated. We designed a study to assess the level of respiratory muscle weakness emerging during the intensive care unit stay in mechanically ventilated patients and to examine the correlation between(More)
The clinical pulmonary infection score-original or modified-has been proposed for the diagnosis and management of ventilator-associated pneumonia. In 79 episodes of suspected pneumonia, we prospectively assessed the diagnostic accuracy of the physicians' clinical assessment of probability and of the modified clinical pulmonary infection score, both measured(More)
OBJECTIVE Sampling techniques for microbiological diagnosis of ventilator-associated pneumonia (VAP) remain debated, and it is unclear to what extent invasive diagnostic techniques impact the management of patients. DESIGN A prospective observational study of 68 first episodes of suspected pneumonia in which specimens were obtained blindly (endotracheal(More)
BACKGROUND The pathogenesis of intensive care unit-acquired paresis (ICUAP), a frequent and severe complication of critical illness, is poorly understood. Since ICUAP has been associated with female gender in some studies, we hypothesized that hormonal dysfunction might contribute to ICUAP. OBJECTIVE To determine the relationship between hormonal status,(More)
OBJECTIVE Neutrophil function impairment is common in nonneutropenic critically ill patients. Whether granulocyte colony-stimulating factor (G-CSF) may be useful for preventing nosocomial infection in these patients is debated. The response of blood neutrophils from critically ill patients to G-CSF was investigated in vitro. DESIGN AND SETTING Prospective(More)
