BACKGROUND ARDS is a heterogeneous syndrome that encompasses lung injury from both direct and indirect sources. Direct ARDS (pneumonia, aspiration) has been hypothesized to cause more severe lung epithelial injury than indirect ARDS (eg, nonpulmonary sepsis); however, this hypothesis has not been well studied in humans. METHODS We measured plasma(More)
RATIONALE Hypoxemia is common during endotracheal intubation of critically ill patients and may predispose to cardiac arrest and death. Administration of supplemental oxygen during laryngoscopy (apneic oxygenation) may prevent hypoxemia. OBJECTIVES To determine if apneic oxygenation increases the lowest arterial oxygen saturation experienced by patients(More)
BACKGROUND The storage duration of red blood cells transfused to critically ill patients is associated with increased morbidity and mortality. Whether the association exists between storage duration of red blood cells transfused to patients with sepsis and the risk of developing ALI/ARDS is unknown. We aimed to determine the association of the storage(More)
INTRODUCTION Plasma levels of cell-free hemoglobin are associated with mortality in patients with sepsis; however descriptions of independent associations with free hemoglobin and free heme scavengers, haptoglobin and hemopexin, are lacking beyond their description as acute phase reactants. We sought to determine the association of plasma levels of(More)
OBJECTIVES Atrial fibrillation has been associated with increased mortality in critically ill patients. We sought to determine whether atrial fibrillation in the ICU is an independent risk factor for death. A secondary objective was to determine if patients with new-onset atrial fibrillation have different risk factors or outcomes compared with patients(More)
OBJECTIVES This trial evaluated the efficacy of acetaminophen in reducing oxidative injury, as measured by plasma F2-isoprostanes, in adult patients with severe sepsis and detectable plasma cell-free hemoglobin. DESIGN Single-center, randomized, double-blind, placebo-controlled phase II trial. SETTING Medical ICU in a tertiary, academic medical center.(More)
OBJECTIVES Platelet activation plays an active role in the pathogenesis of acute respiratory distress syndrome. In our prior study of 575 patients at high risk for acute respiratory distress syndrome, concurrent statin and aspirin use was associated with reduced acute respiratory distress syndrome. However, the largest study (n = 3,855) to date found no(More)
INTRODUCTION Despite recent modifications, the clinical definition of the acute respiratory distress syndrome (ARDS) remains non-specific, leading to under-diagnosis and under-treatment. This study was designed to test the hypothesis that a biomarker panel would be useful for biologic confirmation of the clinical diagnosis of ARDS in patients at risk of(More)
OBJECTIVE To determine the association of circulating cell-free hemoglobin with poor clinical outcomes in patients with sepsis and to characterize the potential protective effects of acetaminophen, an inhibitor of hemoprotein-mediated oxidation. DESIGN Retrospective observational study. PATIENTS A total of 391 critically ill patients with sepsis in(More)
BACKGROUND Millions of patients who survive medical and surgical general intensive care unit care every year experience newly acquired long-term cognitive impairment and profound physical and functional disabilities. To overcome the current reality in which patients receive inadequate rehabilitation, we devised a multifaceted, in-home, telerehabilitation(More)
