BACKGROUND In the later stages of circulatory shock, monitoring should help to avoid fluid overload. In this setting, volume expansion is ideally indicated only for patients in whom the cardiac index (CI) is expected to increase. Crystalloids are usually the choice for fluid replacement. As previous studies evaluating the hemodynamic effect of crystalloids(More)
BACKGROUND The applicability of pulse pressure variation (ΔPP) to predict fluid responsiveness using lung-protective ventilation strategies is uncertain in clinical practice. We designed this study to evaluate the accuracy of this parameter in predicting the fluid responsiveness of septic patients ventilated with low tidal volumes (TV) (6 ml kg(-1)). (More)
OBJECTIVE To evaluate the presence of diabetes mellitus and impaired glucose tolerance in intensive care unit inpatients. METHODS The study included patients in post-surgical care for elective and emergency surgery and excluded those patients with known diabetes mellitus. To diagnose prior serum glucose level disorders, we considered the value of glycated(More)
OBJECTIVE The aim of this study was to evaluate the impact of increased positive end-expiratory pressure on the sublingual microcirculation. METHODS Adult patients who were sedated, under mechanical ventilation, and had a diagnosis of circulatory shock and acute respiratory distress syndrome were included. The positive end-expiratory pressure level was(More)
The growing population of solid organ transplant (SOT) recipients is at a significantly increased risk for developing infections. In some patients, the infection can lead to a dysregulated systemic inflammatory response with acute organ dysfunction. SOT recipients with sepsis tend to have less fever and leukocytosis instances. Moreover, they have diminished(More)
PURPOSE The objective of our study was to assess the reliability of the distensibility index of the inferior vena cava (dIVC) as a predictor of fluid responsiveness in postoperative, mechanically ventilated patients and compare its accuracy with that of the pulse pressure variation (PPV) measurement. MATERIALS AND METHODS We included postoperative(More)
OBJECTIVES The purpose of this study was to test if venous blood drawn from femoral access can be used to estimate the central venous oxygen saturation and arterial lactate levels in critically ill patients. METHODS Bland-Altman analysis and Spearman correlations were used to compare the femoral venous oxygen saturation and central venous oxygen(More)
OBJECTIVES To evaluate the serum concentrations of vitamin D and their variations in patients with severe sepsis or septic shock and in control subjects upon admission and after 7 days of hospitalization in the intensive care unit and to correlate these concentrations with the severity of organ dysfunction. METHODS This case-control, prospective,(More)
