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.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of fentanyl and sufentanil in patients undergoing coronary artery bypass graft surgery.
To compare fentanyl and sufentanil, administered in equipotent concentrations by target-controlled infusion, as components of a balanced anesthetic in patients undergoing coronary artery bypass graft (CABG) surgery. ⋯ When administered in a constant 10:1 concentration ratio, fentanyl and sufentanil do not differ in their ability to facilitate pre-CPB hemodynamic control. Although both opioids were relatively inexpensive, the acquisition cost of fentanyl was less than sufentanil. A recommendation regarding the opioid of choice for routine use in patients undergoing CABG surgery awaits more rigorous studies of recovery and cost after equipotent doses of fentanyl and sufentanil. When combined with isoflurane, effect-site opioid concentrations near the IC50 for electroencephalographic effect provide excellent pre-CPB hemodynamic control in patients undergoing CABG surgery.
