Randomized Controlled TrialEffects of thoracic epidural anesthesia on flow and endothelium of internal thoracic artery in coronary artery bypass graft surgery.
The internal thoracic artery (ITA) is the preferred conduit for coronary artery bypass graft (CABG) surgery. The authors investigated whether thoracic epidural anesthesia (TEA) as an adjunct to general anesthesia (GA) can increase the blood flow of the ITA. ⋯ The results of this study indicated that TEA increased ITA free blood flow significantly via increased VEGF, i-NOS, and adenosine-A2B receptor expressions. Therefore, the use of TEA as an adjunct to GA might be considered as an alternative to vasoactive agents for increasing ITA flow in CABG surgery.

Predictive value of the additive and logistic EuroSCOREs in patients undergoing aortic valve replacement.
The purpose of this study was to evaluate the accuracy of the additive and logistic EuroSCOREs in predicting the operative mortality in patients undergoing aortic valve replacement (AVR) with or without coronary artery bypass graft (CABG) surgery. ⋯ Although the additive and the logistic EuroSCOREs had good discriminatory power, they were not able to predict the actual operative mortality accurately. Both EuroSCOREs overestimated the operative mortality, especially in low-risk patients.

The effect of retrograde autologous priming of the cardiopulmonary bypass circuit on cerebral oxygenation.
The aim of this study was to investigate the effect of retrograde autologous priming (RAP) of the cardiopulmonary bypass (CPB) circuit on cerebral oxygenation. ⋯ The application of RAP to CPB limits the degree of hemodilution and improves cerebral oxygenation during CPB. The present findings suggest a potential benefit of RAP from a neurologic aspect.

Comparative StudyComparison of 5 different remifentanil strategies against myocardial ischemia-reperfusion injury.
The purpose of this study was to investigate the effects of various remifentanil strategies (preconditioning, postconditioning, or continuous infusion) against myocardial ischemia-reperfusion injury. ⋯ Preconditioning or postconditioning by remifentanil and the continuous infusion of remifentanil effectively reduce myocardial infarction, whereas reperfusion targeting ischemic targeting or reperfusion targeting remifentanil does not. Remifentanil preconditioning better preserves myocardial function, especially LVDP, than other remifentanil strategies.
