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.

Randomized Controlled Trial Clinical TrialThe effects of fenoldopam on coronary conduit blood flow after coronary artery bypass graft surgery.
To quantify the effects of fenoldopam, 0.1 microg/kg/min, on left internal mammary artery (LIMA) and saphenous vein blood flow after coronary anastomosis. ⋯ The findings indicate that fenoldopam, 0.1 microg/kg/min, did not influence coronary conduit blood flow to a clinically significant extent. The small increase in LIMA blood flow may be of greater importance in high-risk patients or in the prevention of coronary arterial spasm.

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.
