Clinical TrialIntraoperative transesophageal ultrasonography can measure renal blood flow.
To determine the feasibility of acquiring Doppler-derived indices of renal blood flow by transesophageal ultrasonography in the perioperative period. ⋯ This study demonstrates the ability to acquire two-dimensional images of kidney and renal arterial Doppler velocities using transesophageal ultrasonography during cardiac surgery. Transesophageal renal arterial Doppler waveform analysis can follow changes in renal blood flow patterns secondary to interventional therapy.

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.

Randomized Controlled Trial Clinical TrialEffect of subarachnoid morphine administration on extubation time after coronary artery bypass graft surgery.
To determine the effects of 2 low doses of intrathecal morphine on extubation time and on postoperative analgesic requirements after coronary artery bypass graft (CABG) surgery. ⋯ Despite decreased postoperative morphine requirements, intrathecal morphine administration did not have a clinically relevant effect on extubation time after CABG surgery. This study suggests that 250 microg is the optimal dose of intrathecal morphine to provide significant postoperative analgesia without delaying tracheal extubation.

Randomized Controlled Trial Comparative Study Clinical TrialFast-track cardiac anesthesia: a comparison of remifentanil plus intrathecal morphine with sufentanil in a desflurane-based anesthetic.
To compare the effects of an intravenous remifentanil infusion plus intrathecal morphine with intravenous sufentanil infusion with respect to intraoperative hemodynamic variables, extubation times, and recovery profiles when administered as part of a desflurane-based fast-track anesthetic regimen for cardiac surgery. ⋯ Use of remifentanil in combination with intrathecal morphine did not facilitate earlier tracheal extubation or improve intraoperative hemodynamic stability compared with sufentanil alone for fast-track cardiac anesthesia.
