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)
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)
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)
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)
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)
OBJECTIVES To assess the association between smoking and survival with a good neurologic outcome in patients following cardiac arrest treated with mild therapeutic hypothermia (TH). METHODS We conducted a retrospective observational study of a prospectively collected cohort of 188 consecutive patients following cardiac arrest treated with TH between May(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)
OBJECTIVE To determine whether higher levels of PaO2 are associated with in-hospital mortality and poor neurological status at hospital discharge in patients treated with mild therapeutic hypothermia after sudden cardiac arrest. DESIGN Retrospective analysis of a prospective cohort. PATIENTS A total of 170 consecutive patients treated with therapeutic(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)
