Clinical TrialClinical and economic effects of pulmonary artery catheterization in nonemergent coronary artery bypass graft surgery.
To examine the association between use of pulmonary artery catheterization with hospital outcomes and costs in nonemergent coronary artery bypass graft (CABG) surgery. ⋯ In the setting of nonemergent CABG surgery, pulmonary artery catheterization was associated with an increased risk of in-hospital mortality, greater length of stay, and higher total costs, particularly in hospitals with low volume of PAC use.

Clinical TrialBlood loss from coronary angiography increases transfusion requirements for coronary artery bypass graft surgery.
To determine the blood loss associated with coronary angiography and its impact on hemoglobin and transfusion requirements for subsequent coronary artery bypass graft (CABG) surgery. ⋯ Coronary angiography contributes to a 1.8 g/dL reduction in hemoglobin concentration before CABG surgery and was associated with increased transfusion of allogeneic blood products. Measures aimed at maintaining red cell volume during coronary angiography, increasing erythropoiesis, or delaying surgery beyond 2 weeks may result in a decrease in transfusion requirements for patients undergoing CABG surgery.

Clinical TrialThe effects of transesophageal echocardiography on hemodynamic variables in small infants undergoing cardiac surgery.
To assess the effects of transesophageal echocardiography (TEE) on hemodynamic variables during cardiac surgery in small infants. ⋯ Although hemodynamic compromise can occur in small infants, this study suggests that it is infrequent. Fear of hemodynamic compromise should not prevent use of intraoperative TEE in small infants when otherwise indicated.

Randomized Controlled Trial Clinical TrialRenal effects of amino acid infusion in cardiac surgery.
To evaluate effects of amino acids on renal function and oxygen consumption and the role of individual amino acids on renal blood flow (RBF) changes. ⋯ The increase in RBF from a mixed amino acid infusion was associated with increased glomerular filtration rate and renal consumption of oxygen. Changes in RBF of a mixed amino acid infusion could not be linked to plasma level or renal uptake of any individual amino acids.
