Comparative StudyOff-pump coronary artery bypass grafting reduces postoperative neurologic complications.
Complications occurring after coronary artery bypass graft (CABG) surgery, particularly neurologic damage, have been mainly correlated with the use of cardiopulmonary bypass (CPB). The aim of this work was to compare postoperative outcomes of patients undergoing CABG surgery, with or without the use of CPB, focusing on neurologic events. ⋯ In the authors' experience, off-pump CABG surgery offers some benefits compared with CPB in respect to major neurologic complications.

Comparative StudyImmediate extubation after aortic valve surgery using high thoracic epidural analgesia or opioid-based analgesia.
Fast-track anesthesia has gained widespread use in cardiac centers around the world. No study has been published focusing on immediate extubation after aortic valve surgery. This study examines the feasibility and hemodynamic stability of immediate extubation after simple or combined aortic valve surgery using either thoracic epidural analgesia or opioid-based analgesia. ⋯ Immediate extubation is feasible after aortic valve surgery using either high thoracic epidural analgesia or opioid-based analgesia; both techniques maintain hemodynamic stability throughout surgery. TEA provides superior pain control.

The mechanisms of the direct vascular effects of fentanyl on isolated human saphenous veins in vitro.
The purpose of this study was to determine the mechanism of the direct effects of fentanyl on human veins in vitro. ⋯ The present results show that fentanyl causes vasodilatation via both endothelium- and opioid receptor-independent mechanisms in the human saphenous vein. The relaxant effects of fentanyl are probably via activation of K+ channel and Na+K+-adenosine trisphosphatase and inhibition of Ca++ channel.
