OBJECTIVE To determine the usefulness of systematic intraoperative transesophageal echocardiography in a cardiac surgical unit. DESIGN Open prospective observational survey. SETTING University Hospital. PARTICIPANTS Consecutive adult patients (n = 203) undergoing elective or urgent cardiac operations. MEASUREMENTS AND MAIN RESULTS(More)
BACKGROUND In patients after lung transplantation, dysfunction of pulmonary venous and artery anastomoses leading to reoperation is described. METHODS AND RESULTS Pulmonary artery and vein anastomoses were evaluated intraoperatively by monoplane transesophageal echocardiography (TEE) in 18 patients undergoing lung transplantation (nine right, five left(More)
To evaluate the clinical utility of a new device for continuous noninvasive cardiac output monitoring (NICOM) based on chest bio-reactance compared with cardiac output measured semi-continuously by thermodilution using a pulmonary artery catheter (PAC-CCO). Prospective, single-center study. Intensive care unit. Consecutive adult patients immediately after(More)
INTRODUCTION This study was designed to test the hypothesis of equivalence in cardiac output (CO) and stroke volume (SV) monitoring capabilities of two devices: non invasive transthoracic bioreactance (NICOM), and a pulse contour analysis (PICCO PC) coupled to transpulmonary thermodilution (PICCO TD). METHODS We included consecutive patients of a single(More)
To study the feasibility of predicting fluid responsiveness (FR) by passive leg raising (PLR) using a Bioreactance-based noninvasive cardiac output monitoring device (NICOM). This prospective, two-center study included 75 consecutive intensive care unit (ICU) adult patients immediately after cardiac surgery. NICOM was used to continuously record cardiac(More)
The purpose of this study was to assess the efficacy of clonidine in achieving perioperative hemodynamic stability in patients undergoing coronary artery bypass grafting performed under high-dose alfentanil anesthesia. Twenty-four patients with left ventricular ejection fraction greater than 0.5 were prospectively studied in a double-blind manner; those(More)
BACKGROUND Right ventricle (RV) preload assessment remains controversial because the complexity of RV geometry is an obstacle to wall stress modeling. We developed a method to evaluate end-diastolic RV elastic energy (EL), a variable that integrates all the stretching effects of venous return and that can be easily estimated at the bedside from the area(More)
The hemodynamic effects of enoximone and nicardipine were compared during the early postcardiac surgery period in 40 patients with systemic hypertension and moderate cardiac dysfunction. Patients were prospectively randomized into two groups. Mean right atrial pressure was maintained above 7 mm Hg. The drug infusion rate was adjusted to maintain mean(More)
