Clinical TrialTransesophageal echocardiography values for left ventricular end-diastolic area and pulmonary vein and mitral inflow Doppler velocities in patients undergoing coronary artery bypass graft surgery.
To determine left ventricular end-diastolic area (EDA) and pulmonary vein and mitral inflow Doppler velocities in patients undergoing coronary artery bypass graft (CABG) surgery using transesophageal echocardiography (TEE). To examine the effects of age, sex, and left ventricular function on these values. ⋯ Values are presented for a predominantly white population undergoing cardiac surgery. Left ventricular dysfunction is associated with increased left ventricular EDA measurements.

Clinical TrialSubtle brain damage cannot be detected by measuring neuron-specific enolase and S-100beta protein after carotid endarterectomy.
To assess whether subtle brain damage after carotid endarterectomy could be detected using serum levels of neuron-specific enolase (NSE) or S-100beta protein. ⋯ Subtle brain damage after carotid artery surgery could not be detected by measuring blood levels of NSE and S-100beta protein. The NSE level was significantly higher before carotid artery surgery and decreased postoperatively to the level observed in aortic surgery.

Clinical TrialReactive hyperemia in skin after cardiopulmonary bypass.
To study reactive hyperemia (RH) using a transcutaneous PO2/PCO2 combination electrode heated to 37 degrees C and tissue reflectance spectrophotometry in patients before and after cardiopulmonary bypass (CPB) to determine whether microcirculatory function of skin is altered. ⋯ Cutaneous microcirculation assessed by RH is well preserved during the immediate postoperative period in patients undergoing uncomplicated coronary artery surgery with CPB.

Clinical TrialIs the placement of a pulmonary artery catheter still justified solely for the measurement of cardiac output?
The authors compared four clinical techniques of measuring cardiac output (CO) in critically ill patients: pulmonary artery thermodilution (CO[PA]), transpulmonary aortic thermodilution (CO[AORTA]), Fick principle-derived (CO[FICK]), and continuous pulmonary artery (CCO) measurements. ⋯ The correlations among the four CO techniques were high and similar, with CO(PA) and CO(AORTA) techniques showing the highest agreement. Because CO with similar accuracy can be obtained from transpulmonary aortic thermodilution in a less-invasive manner, it appears that the placement of a pulmonary artery catheter solely for the measurement of CO is no longer justified, unless continuous CO measurements are needed.

Comparative Study Clinical TrialBeat-to-beat measurement of cardiac output by intravascular pulse contour analysis: a prospective criterion standard study in patients after cardiac surgery.
To evaluate the accuracy of a new pulse contour method of measuring cardiac output in critically ill patients. ⋯ Bias and precision are acceptable, and the system provides results that agree with conventional thermodilution. This study demonstrates the clinical applicability of the pulse contour cardiac output monitoring system.
