Comparative StudyTransmitral flow propagation velocity and assessment of diastolic function during abdominal aortic aneurysm repair.
In the perioperative arena, pronounced changes in cardiac loading conditions can make assessment of diastolic parameters difficult. A number of Doppler techniques have been introduced to assess perioperative diastolic function. ⋯ Vp assessment identified the majority (93%) of cases of diastolic dysfunction identified by traditional methods. Furthermore, the incidence of diastolic dysfunction increased with application of the AXC but returned to baseline after removal.

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

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.
