Acute respiratory distress syndrome (ARDS) is characterized by the presence of fibrin-rich inflammatory exudates in the intra-alveolar spaces and the extensive migration of neutrophils into alveoli of the lungs. Tissue factor (TF)-dependent procoagulant properties of bronchoalveaolar lavage fluid (BALF) obtained from ARDS patients favor fibrin deposition,(More)
BACKGROUND Separation from mechanical ventilation is a difficult task, whereas conventional predictive indices have not been proven accurate enough, so far. A few studies have explored changes of breathing pattern variability for weaning outcome prediction, with conflicting results. In this study, we tried to assess respiratory complexity during weaning(More)
OBJECTIVE To investigate the respiratory, metabolic and hemodynamic effects of clonidine in ventilated patients presenting with withdrawal syndrome after sedation interruption. DESIGN Prospective, interventional, single-center study in 30 ventilated ICU patients. INTERVENTIONS Metabolic [oxygen consumption (VO(2)), CO(2) production (VCO(2)), resting(More)
OBJECTIVE To determine whether selective decontamination locally in the subglottic area (SDSA) reduces tracheal colonization and prevents ventilator-associated pneumonia (VAP) in patients with multiple trauma. DESIGN AND SETTING A prospective randomized, controlled, clinical study in a 14-bed general intensive care unit of a university hospital. (More)
The purpose of this study was to evaluate right ventricular (RV) loading and cardiac output changes, by using the thermodilution technique, during the mechanical ventilatory cycle. Fifteen critically ill patients on mechanical ventilation, with 5 cmH(2)O of positive end-expiratory pressure, mean respiratory frequency of 18 breaths/min, and mean tidal volume(More)
BACKGROUND Sepsis is associated with systemic inflammatory responses and induction of coagulation system. Neutrophil extracellular traps (NETs) constitute an antimicrobial mechanism, recently implicated in thrombosis via platelet entrapment and aggregation. METHODOLOGY/PRINCIPAL FINDINGS In this study, we demonstrate for the first time the localization of(More)
Cold-stored arteries, tissues or organs are transferred in vascular, reconstructive and transplantation surgery. The function of transferred vessels and tissues diminishes when infection complicates transplantation, thereby contributing to morbidity. To evaluate the mechanisms involved, the effects of cold storage on basal vascular reactivity and the(More)
INTRODUCTION Sputum Gram stain and culture have been said to be unreliable indicators of the microbiological diagnosis of bacterial pneumonia. The etiological diagnosis of pneumonia is surrounded by great degree of uncertainty. This uncertainty should be and can be calculated and incorporated in the diagnosis and treatment. STUDY OBJECTIVES To determine(More)
Ventilator-associated pneumonia is the most common nosocomial infection in the intensive care unit, and it is associated with prolonged hospitalization, increased health care costs, and high attributable mortality. During the past several decades, numerous studies focused on the crucial role of the endotracheal tube (ETT) in the pathogenesis of(More)
