To investigate the mechanism(s) responsible for the depletion of corticosteroid-binding globulin (CBG) activity in serum in septic shock, we developed a radioimmunoassay (RIA) for human CBG, using a monospecific antiserum to human CBG raised in rabbits. CBG was purified from pooled human serum by precipitation with ammonium sulfate and successive affinity(More)
STUDY OBJECTIVES Contrast transthoracic echocardiography (TTE) is currently used to identify intrapulmonary shunt (IPS) in patients with end-stage liver disease. The aim of this study was to compare the use of contrast TTE and transesophageal echocardiography (TEE) in detecting IPS. DESIGN Thirty-seven consecutive outpatients with severe liver disease(More)
To explore the main factors which could be involved in the fluid retention induced by continuous positive pressure ventilation (CPPV), hemodynamics, renal, and hormonal parameters were measured in seven intensive care patients during three consecutive 60-min periods; one of intermittent positive pressure ventilation (IPPV), one of CPPV (PEEP 10 cmH2O), and(More)
STUDY OBJECTIVE To assess the usefulness of quantification of infected cells (ICs) in BAL fluid for the diagnosis of ventilator-associated pneumonia (VAP). DESIGN A prospective study. SETTING A medico-surgical ICU in a tertiary health-care institution. PATIENTS One hundred thirty-two patients (mean age, 52 +/- 19 years). The suspicion of nosocomial(More)
We examined end-tidal CO2 tension (PETCO2) and pulmonary CO2 elimination of CO2 (VECO2) during CO2 insufflation under general anesthesia for three surgical procedures: gynecologic laparoscopy (intraperitoneal CO2 insufflation for 43 +/- 4 min), laparoscopic cholecystectomy (intraperitoneal CO2 insufflation for 125 +/- 14 min), and pelviscopy(More)
This study was designed to determine the significance of changes in mixed venous oxygen saturation (SVO2) associated with aortic surgery. In 12 patients undergoing aortic aneurysm repair, SVO2 was monitored using a fiberoptic pulmonary arterial catheter, and oxygen uptake (VO2) was measured at 2-min intervals by a mass-spectrometer system. Excluding the(More)
The oxygen cost of breathing and the time integral of the transdiaphragmatic pressure were measured at the onset of the weaning period in eight patients with chronic obstructive pulmonary disease requiring mechanical ventilation. Measurements were achieved during continuous positive airway pressure ventilation and during 15 cmH2O pressure support(More)
Fat embolism syndrome (FES) is a rare but serious complication occurring after long bone fractures. Presence of fat droplets in cells obtained by bronchoalveolar lavage has been proposed as a specific tool for FES diagnosis in trauma patients. We evaluated this technique over a 15-month period in 85 patients. Twenty-eight patients were excluded. The(More)
It is well established that muscle-relaxant drugs may be responsible for anaphylactoid reactions during anesthesia. In this study, we developed an in vitro test with a commercially available solid phase for the detection of specific IgE directed to the tertiary or quaternary ammonium groups of neuromuscular-blocking drugs. The solid-phase complex was(More)
