Non-invasive cardiac output determination by two-dimensional independent Doppler during and after cardiac surgery.
PURPOSE This study was to compare noninvasive measurement of cardiac output (CO) using a novel Doppler technique with invasive CO measurements in the postcardiac surgical intensive care unit. DESCRIPTION Thirty-six patients (67.2 +/- 10 years, New York Heart Association functional class 3.1 +/- 0.3) undergoing coronary revascularization were prospectively examined postoperatively. One hundred...
متن کاملNon-invasive ventilation after cardiac surgery
Anaesthesia and surgery induce major changes in respiratory function, in particular when the thorax or the upper abdomen are involved. Pulmonary volumes decrease, and atelectasis can develop. Postoperative pain and diaphragm dysfunction further worsen the respiratory function, contributing to the risk of acute respiratory failure. non-invasive ventilation proved to be beneficial in the postoper...
متن کاملNon-invasive cardiac output monitoring.
Outcomes in the management of critically ill patients may be improved using goal-directed peri-operative haemodynamic monitoring. A conservative approach may no longer be acceptable but in view of the significant morbidity associated with balloon tipped flow directed pulmonary artery catheters a non-invasive approach would be preferable. In this review we consider the different non-invasive tec...
متن کاملLess invasive indicators of changes in thermodilution cardiac output by ventilatory changes after cardiac surgery.
BACKGROUND AND OBJECTIVE We studied whether changes in less invasive, noncalibrated pulse-contour cardiac output (by modified ModelFlow, COmf) and derived stroke volume variations (SVV), as well as systolic and pulse pressure variations, predict changes in bolus thermodilution cardiac output (COtd), evoked by continuous and cyclic increases in intrathoracic pressure by increases in positive end...
متن کاملPrediction of fluid responsiveness using a non-invasive cardiac output monitor in children undergoing cardiac surgery.
BACKGROUND This study evaluated the ability of a non-invasive cardiac output monitoring device (NICOM) to predict fluid responsiveness in paediatric patients undergoing cardiac surgery. METHODS Children aged <5 yr undergoing congenital heart surgery were included. Once the sternum had been closed after repair of the congenital heart defect, 10 ml kg(-1) colloid solution was administered for v...
