INTRODUCTION Inadequate initial treatment and delayed hemodynamic stabilization (HDS) may be associated with increased risk of death in severe sepsis patients. METHODS In order to compare the hemodynamic efficacy and safety of 6% HES 130/0.4 and NaCl 0.9% for HDS in patients with severe sepsis, we designed a prospective, multicenter, active-controlled,(More)
IMPORTANCE Evidence supporting the choice of intravenous colloid vs crystalloid solutions for management of hypovolemic shock remains unclear. OBJECTIVE To test whether use of colloids compared with crystalloids for fluid resuscitation alters mortality in patients admitted to the intensive care unit (ICU) with hypovolemic shock. DESIGN, SETTING, AND(More)
OBJECTIVES To confirm early, marked decrease in plasma selenium concentrations in patients admitted to a surgical and medical intensive care unit (ICU), and to study this decrease according to the presence or absence of systemic inflammatory response syndrome (SIRS), sepsis, or direct ischemia-reperfusion. DESIGN Prospective, observational study. (More)
INTRODUCTION Sepsis is associated with the generation of oxygen free radicals and (lacking) decreased selenium plasma concentrations. High doses of sodium selenite might reduce inflammation by a direct pro-oxidative effect and may increase antioxidant cell capacities by selenium incorporation into selenoenzymes. We investigated the effects of a continuous(More)
PURPOSE OF REVIEW To assess the current role of selenium supplementation in critically ill patients. RECENT FINDINGS Studies consistently demonstrate decreased selenium concentration in plasma and whole blood in some critically ill patients, especially those with septic shock, and have suggested that persistent low concentrations may be associated with(More)
RATIONALE The occurrence of ventilator-associated pneumonia (VAP) is linked to the aspiration of contaminated pharyngeal secretions around the endotracheal tube. Tubes with cuffs made of polyurethane rather than polyvinyl chloride or with a conical rather than a cylindrical shape increase tracheal sealing. OBJECTIVES To test whether using polyurethane(More)
BACKGROUND The risk of bacterial contamination related to epidural analgesia in patients cared for in the intensive care unit has not been assessed. Thus the authors studied patients who received care in the intensive care unit who were given epidural analgesia for more than 48 h to determine the rates of local, epidural catheter, and spinal space infection(More)
RATIONALE A decade after drotrecogin alfa (activated) (DAA) was released on the market worldwide, its benefit-to-risk ratio remains a matter of debate. OBJECTIVES The current investigator-led trial was designed to evaluate the efficacy and safety of DAA, in combination with low-dose steroids, in adults with persistent septic shock. METHODS This was a(More)
Administration of sodium selenite in septic shock has been associated with apparently conflicting results that may be related to different dosing schedules. Bolus administration, leading to a transient pro-oxidative effect, could limit the inflammatory reaction and improve outcomes. We studied 21 anesthetized, mechanically ventilated, invasively monitored,(More)
BACKGROUND/AIMS Oxidative stress is involved in sepsis-related endothelium dysfunction. Selenoprotein-P (Sel-P), the main plasma selenoprotein, may have high antioxidant potential, and binds to endothelium. We hypothesize that, in septic shock, and similar syndromes such as systemic inflammatory response syndrome (SIRS), Sel-P binds massively to(More)
