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.

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.

Clinical TrialThe effects of recent aspirin ingestion on platelet function in cardiac surgical patients.
To examine the effects of the preoperative aspirin-free interval on platelet function in cardiac surgical patients. ⋯ Cardiac surgical patients who ingest aspirin < or =2 days preoperatively have greater impairment of platelet function than patients who have a longer preoperative aspirin-free interval.

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.

Clinical TrialPlatelet glass bead retention predicts bleeding after cardiac surgery.
To determine if the platelet glass bead retention assay can predict bleeding after cardiac surgery. ⋯ The platelet glass bead retention assay measures dynamic platelet function and is sensitive to the CPB-induced adhesion and aggregation defect and correlates with postoperative blood loss. Modification of this platelet function assay used with the prothrombin time may provide a simple and effective diagnostic approach to bleeding after CPB.
