OBJECTIVES To determine whether peak systolic velocity of tricuspid annular motion assessed by tissue Doppler echocardiography (Sta), a right ventricular function parameter, can discriminate patients with true- and false-positive pulse pressure variation. Pulse pressure variation is used to predict fluid responsiveness in mechanically ventilated patients.(More)
OBJECTIVES Enterococci may increase morbidity and mortality in elderly patients with intra-abdominal infections (IAIs) hospitalized in the intensive care unit (ICU). PATIENTS AND METHODS A single-centre, retrospective evaluation of an ICU database (1997-2007) of elderly ICU patients (≥75 years) with a severe IAI was performed. Demographics, severity(More)
INTRODUCTION We have almost no information concerning the value of inferior vena cava (IVC) respiratory variations in spontaneously breathing ICU patients (SBP) to predict fluid responsiveness. METHODS SBP with clinical fluid need were included prospectively in the study. Echocardiography and Doppler ultrasound were used to record the aortic velocity-time(More)
OBJECTIVES The passive leg-raising maneuver is a reversible fluid-loading procedure used to predict fluid responsiveness in mechanically ventilated patients. The aim of the present study was to determine whether intra-abdominal hypertension (which impairs venous return) reduces the ability of passive leg raising to detect fluid responsiveness in critically(More)
Dear Editor, Respiratory variation of pulse pressure (DPP) has been demonstrated to accurately predict fluid responsiveness in mechanically ventilated patients [1, 2]. Unfortunately, determination of DPP requires offline calculation or a dedicated device [1]. A new algorithm included in the Philips IntelliVue MP 70 monitor has been recently developed for(More)
The measurement of transcutaneous PtcO2 in eight normal adults prove a comparable efficacy of 50 l.min-1 O2 through facial "small mask" (61.5 kPa; 463 mmHg) and 20 l.min-1 O2 through head tent (65.1 kPa; 490 mmHg). First procedure, inexpensive, is very simple to use.
When tracheal intubation is conducted with traditional laryngoscope PtcO2 fall during the first minute after intubation; when continuous O2 supplied laryngoscope (Laryng O2) is used PtcO2 rise; the difference is statistically significant (p less than 0.001) either the subjects are in curarisation apnea or in spontaneous ventilation. With traditional(More)
OBJECTIVES Resistance to all β-lactams is emerging among Pseudomonas aeruginosa (PA) clinical isolates. Aztreonam and cefepime act synergistically in vitro against AmpC overproducing PA isolates. The objective of this study was to evaluate the clinical efficacy of this treatment in ICU patients infected with multidrug-resistant PA. MATERIAL AND METHODS(More)
