Comparative StudyThe agreement between ventricular volumes and ejection fraction by transesophageal echocardiography or a combined radionuclear and thermodilution technique in patients after coronary artery surgery.
To study the reproducibility of and agreement between perioperative transesophageal echocardiographic (TEE) and radionuclide (RN) assessment of ventricular volumes and ejection fraction (EF). ⋯ EF measured by TEE area length and Simpson's rule method are as reproducible as TEE FAC and are more accurate estimates of RN EF. Poor agreement between methods of measuring end-diastolic volume was observed.

Randomized Controlled Trial Comparative Study Clinical TrialThe effect of midazolam at two plasma concentrations of hemodynamics and sufentanil requirement in coronary artery surgery.
In this study, the hemodynamics and sufentanil requirement were compared at two midazolam target plasma concentrations in patients undergoing coronary artery bypass grafting (CABG). ⋯ In patients undergoing CABG, good hemodynamic control with a similar incidence of hemodynamic interventions was observed at midazolam target plasma concentrations of 150 and 300 ng/mL when coadministered with sufentanil. The sufentanil requirement was identical in both groups. This study suggests that a midazolam plasma concentration of 150 ng/mL is sufficient to provide satisfactory hemodynamic control and to avoid intraoperative awareness.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of hetastarch with albumin for postoperative volume expansion in children after cardiopulmonary bypass.
Hetastarch has been studied as a volume expander in adults after cardiopulmonary bypass (CPB) and in recommended dosages has not altered coagulation studies or increased clinical bleeding. Hetastarch was compared with albumin in children after CPB to determine whether hetastarch use was associated with increased clinical bleeding or alteration of coagulation studies. ⋯ This study demonstrated that 6% hetastarch is safe and an effective plasma volume expander in the postoperative management of children, using volumes up to 20 mL/kg. Close laboratory monitoring and careful evaluation of clinical bleeding are suggested when larger doses of hetastarch are administered because of prolongation of the prothrombin time with more than 20 mL/kg of hetastarch.
