The relationship between cerebral oxygen saturation changes and postoperative cognitive dysfunction in elderly patients after coronary artery bypass graft surgery.
The aim of this study was to evaluate the predictive value of cerebral regional oxygen saturation (rSO(2)) in the occurrence of postoperative cognitive dysfunction (POCD) in elderly patients undergoing coronary artery bypass graft (CABG) surgery. ⋯ Intraoperative cerebral oxygen desaturation is associated with early and late POCD in elderly patients. Cerebral oximetry is a promising tool in the prediction of subtle neuropsychologic deficits and further studies are needed.

Randomized Controlled TrialMyocardial protection with isoflurane during off-pump coronary artery bypass grafting: a randomized trial.
To analyze the hemodynamic effects and myocardial injury using troponin-T and creatine phosphokinase (CPK-MB) with isoflurane and compare it with a control group in patients undergoing off-pump coronary artery bypass (OPCAB) surgery. ⋯ Isoflurane provides protection against myocardial damage in a clinically used dosage as documented by lower levels of troponin-T in patients undergoing OPCAB surgery.

Usefulness of monitoring platelet function by multiple electrode aggregometry in primary coronary artery bypass surgery.
Antiplatelet therapy commonly is used for the prevention of cardiovascular complications but increases the risk of perioperative bleeding. Multiple-electrode aggregometry (MEA) was investigated for monitoring platelet inhibition by acetylsalicylic acid (ASA) and clopidogrel in patients undergoing elective coronary artery bypass graft (CABG) surgery with regard to clinical outcome as measured by postoperative blood loss and transfusion requirements. ⋯ MEA is a suitable method for the detection of platelet inhibition by ASA and clopidogrel in patients undergoing CABG surgery. In these patients, preoperative ADP MEA seems to indicate patients at risk for postoperative transfusion requirements.

Transfusion requirements in 811 patients during and after cardiac surgery: a prospective observational study.
To identify patients at risk for intra- and postoperative blood product transfusion in a mixed adult cardiac surgical patient population. ⋯ The identification of high-risk patients is necessary to optimize the perioperative management of bleeding complications. Because of the high variability in transfusion requirements, a specifically tailored patient intervention based on the individual's risk profile appears more likely to improve patient outcome compared with general interventions given to the entire patient group.

Randomized Controlled TrialThe effect of nasogastric tube application during cardiac surgery on postoperative nausea and vomiting--a randomized trial.
Postoperative nausea and vomiting (PONV) are significant morbidities following cardiac surgery. The purpose of this study was to determine if application of a nasogastric (NG) tube during cardiac surgery can reduce the prevalence of postoperative PONV. ⋯ Use of an NG tube during cardiac surgery may reduce the incidence of postoperative vomiting.
