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.

Clinical TrialPreliminary report on high thoracic epidural analgesia: relationship between its therapeutic effects and myocardial blood flow as assessed by stress thallium distribution.
To extend the duration of high thoracic epidural analgesia (HTEA) treatment compared with the authors' previous studies, to test the hypothesis that the mechanism by which HTEA reduces angina during long-term treatment includes an improvement in myocardial blood flow distribution and a reduction in stress-induced ischemia, and to show that new myocardial infarctions are not masked or missed in patients receiving HTEA. ⋯ The authors previously showed that HTEA is safe and effective in relieving refractory angina pectoris. The current study shows that this therapeutic effect persists and does not appear to be related to a change in myocardial blood flow; rather the improvement in symptoms probably results, in part, from an anesthetic effect. HTEA does not mask the development of new myocardial infarctions.

Thoracic epidural analgesia: its role in postthoracotomy atrial arrhythmias.
To determine the effects of thoracic epidural analgesia (TEA) management on the incidence of atrial arrhythmias (AAs) after thoracotomy for lung resection. ⋯ AAs after thoracotomy were common. These AAs were associated with increased age, cardiac history, abnormal ECG, increased cost, increased length of hospital stay, and time of epidural catheter removal. Although a cause-and-effect relationship cannot be inferred from this study, the presence or absence of TEA was found to have a temporal relationship with the incidence of AAs.

The effects of aprotinin on blood product transfusion associated with thoracic aortic surgery requiring deep hypothermic circulatory arrest.
To compare the effects of aprotinin on blood product use and postoperative complications in patients undergoing thoracic aortic surgery requiring deep hypothermic circulatory arrest. ⋯ Low-dose aprotinin administration significantly decreases blood product transfusion requirements in the setting of thoracic aortic surgery requiring deep hypothermic circulatory arrest, and it does not appear to be associated with renal or myocardial dysfunction.
