BACKGROUND AND OBJECTIVE: Tissue Doppler echocardiography is proposed to be a relatively preload independent tool for assessment of diastolic function. No data exist on anaesthetized patients in whom myocardial contractility, vascular tone and baroreceptor reflexes are depressed. The aim of this study was to evaluate the effects of preload alterations ...
Mayer J - - 2007
Thermodilution technique using a pulmonary artery catheter (PAC) is a widely used method to determine cardiac output (CO). It is increasingly criticized because of its invasiveness and its unclear risk-benefit ratio. Thus, less invasive techniques for measuring CO are highly desirable. We compared a new, semi-invasive device (FloTrac/Vigileo) using arterial ...
Schiller Wolfgang - - 2007
BACKGROUND: In coronary artery bypass surgery the detection of the target vessels can be difficult due to their intramural location, coverage by adipose tissue, calcification, or fibrous tissue formation. Their identification is especially critical during off-pump coronary artery bypass (OPCAB) and minimally invasive direct coronary artery bypass (MIDCAB) surgeries. Our ...
