Comparative StudyDifferential expression in markers for thrombin, platelet activation, and inflammation in cell saver versus systemic blood in patients undergoing on-pump coronary artery bypass graft surgery.
Elimination of cardiotomy suction increases reliance on cell-saver blood-conservation techniques. Reinfusion of processed cell-saver blood (PCSB) even without using cardiotomy field suction may contribute to thrombin, cytokines, platelet activators, and hemolytic factors measured systemically. ⋯ Reinfusion of PCSB directly and independently contributes to systemic elevations in interleukin-8, polymorphonuclear elastase, neuron-specific enolase, and S-100beta, augmenting and perhaps accentuating the postoperative inflammatory response. Further evaluation and improvement in cell-salvaging technology and processing techniques are warranted.

Randomized Controlled Trial Comparative StudyCerebral near-infrared spectroscopy in adult patients after cardiac surgery is not useful for monitoring absolute values but may reflect trends in venous oxygenation under clinical conditions.
Cerebral near-infrared spectroscopy (NIRS) was evaluated for use in monitoring global oxygenation in adult patients after cardiac surgery. ⋯ Cerebral NIRS in adult patients might not be the tool to replace mixed venous oxygen monitoring. Further work has to be done to assess its potential to reflect intraindividual trends.

Comparative StudyInferior vena cava diameter and central venous pressure correlation during cardiac surgery.
The purpose of this study was to determine whether a relationship exists between the inferior vena cava diameter (IVCD) or the superior vena cava diameter (SVCD) measured at the point of entry into the right atrium using transesophageal echocardiography (TEE) and the central venous pressure (CVP) under different experimental conditions. ⋯ A strong correlation between TEE-derived IVCD measured at the point of entry into the right atrium and CVP was observed in cardiac surgical patients when CVP was
