Comparative Study Clinical TrialA comparison of neuropsychologic deficits after extracardiac and intracaradiac surgery.
To compare the incidence of neuropsychologic deficits 1 week and 6 months after coronary artery bypass graft (CABG) surgery (extracardiac) and valve surgery with or without CABG surgery (intracardiac) using reliable change indices to define the incidence of neuropsychologic deficits. ⋯ There are some differences in the neuropsychologic outcome of extracardiac and intracardiac surgery. Patients undergoing isolated CABG surgery showed a greater reduction in the incidence of persisting deficits at 6 months than patients undergoing valve surgery with or without CABG surgery. This finding warrants further investigation, with particular attention to patients undergoing combined valve and coronary artery procedures.

Randomized Controlled Trial Clinical TrialCorrelation of peripheral venous pressure and central venous pressure in surgical patients.
To determine the degree of agreement between central venous pressure (CVP) and peripheral venous pressure (PVP) in surgical patients. ⋯ Under the conditions of this study, PVP showed a consistent and high degree of agreement with CVP in the perioperative period in patients without significant cardiac dysfunction. PVP -2 was useful in predicting CVP over common clinical ranges of CVP. PVP is a rapid noninvasive tool to estimate volume status in surgical patients.

Randomized Controlled Trial Clinical TrialElectric impedance for evaluation of body fluid balance in cardiac surgical patients.
To evaluate whether electric impedance can be used to monitor body fluid balance and fluid distribution in cardiac surgical patients. ⋯ Alterations in electric impedance closely follow changes in fluid balance during the perioperative period. This method can be used in clinical practice to control postoperative body fluid balance in cardiac surgical patients.

Comparative Study Clinical TrialEarly neurobehavioral disorders after cardiac surgery: a comparative analysis of coronary artery bypass graft surgery and valve replacement.
To analyze neurobehavioral disorders in the early postoperative period after valve replacement and coronary artery bypass graft (CABG) surgery. ⋯ These results indicate that patients after valve replacement surgery have a higher risk of postoperative neuropsychologic alterations mainly attributable to temporal lobe dysfunction. This finding corresponds to a specific vulnerability of hippocampal structures to transient hypoxia.

Comparative Study Clinical TrialComparison of two sites of inflow pressure measurement during retrograde cerebral perfusion.
To determine whether internal jugular venous valves influence inflow pressure during retrograde cerebral perfusion. ⋯ Internal jugular venous valves can obstruct retrograde cerebral perfusion inflow, manifest by an inflow pressure difference between the superior vena cava and internal jugular vein. In the presence of competent internal jugular venous valves, measurement of inflow pressure in the superior vena cava may be an inaccurate estimate of actual cerebral perfusion pressure. Internal jugular vein pressure should be monitored to avoid inadvertent cerebral hypoperfusion.
