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.
