Randomized Controlled Trial Comparative Study Clinical TrialThe effect of high-frequency ventilation of the lungs on postbypass oxygenation: A comparison with other ventilation methods applied during cardiopulmonary bypass.
To compare the effect of high-frequency ventilation versus other ventilation methods applied during cardiopulmonary bypass on postbypass oxygenation. ⋯ The alveolar-arterial oxygen gradient was lower, and the PaO(2) was higher 5 minutes after bypass in patients receiving CPAP (100% O(2)) as compared with those ventilated with high-frequency ventilation.

A case series of low-dose fenoldopam in seventy cardiac surgical patients at increased risk of renal dysfunction.
To evaluate the usefulness of low-dose fenoldopam mesylate in patients at risk of developing renal dysfunction after cardiac surgery requiring cardiopulmonary bypass. ⋯ These findings suggest that renal function was preserved in patients at increased risk for renal dysfunction after cardiac surgery when low-dose fenoldopam was used in the perioperative period. However, a randomized, controlled trial is required to establish efficacy.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of three remifentanil dose-finding regimens for coronary artery surgery.
To identify the remifentanil dosing regimen providing safe and optimal anesthetic conditions during coronary artery bypass graft surgery and to evaluate postoperative recovery characteristics. ⋯ After lorazepam premedication, remifentanil infusion (2-4 microg/kg/min) supplemented intermittently with low inspired concentrations of isoflurane provided an effective anesthetic regimen for coronary artery bypass graft surgery. Early extubation times were feasible after remifentanil continuous infusions (1-5 microg/kg/min) used as the primary anesthetic component intraoperatively and for analgesia (

Comparative Study Clinical TrialThe effects of remifentanil and thoracic epidural on oxygenation and pulmonary shunt fraction during one-lung ventilation.
To compare the effects of remifentanil and thoracic epidural analgesia on the hemodynamic changes and pulmonary shunt fraction during one-lung ventilation (OLV) for thoracotomy. ⋯ Both remifentanil infusion and TEA are suitable for analgesia during thoracic surgery when OLV is used. There was no significant difference in PaO(2) and Qs/Qt during each administration.
