Flow dependency of error in thermodilution measurement of cardiac output during acute tricuspid regurgitation.
To evaluate the effect of variable degrees of tricuspid regurgitation on thermodilution cardiac output measurements during changes in venous return. ⋯ These data show that acute tricuspid regurgitation may produce underestimation of cardiac output by thermodilution when flow is relatively high, produce overestimation when flow is relatively low, or have minimal effect when flow is in the midrange.

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.
